Balancing cleaner air with rising incomes is not a luxury question for developing countries. It is a real-world, and real-life, policy problem that shapes health, jobs, and the future of their cities.



A new <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">study</a> lays out when zero emissions can go hand in hand with steady <a href="https://www.earth.com/news/rising-temperatures-will-cut-world-gdp-by-a-staggering-40-percent-if-nothing-changes/">growth</a>, even when governments rely on foreign aid.



<h2 class="wp-block-heading" id="h-zero-emissions-and-economic-growth">Zero emissions and economic growth</h2>



The work comes from <a href="https://tus.elsevierpure.com/en/persons/hideo-noda" target="_blank" rel="noreferrer noopener">Hideo Noda</a> at the Tokyo University of Science (<a href="https://www.tus.ac.jp/en/" target="_blank" rel="noreferrer noopener">TUS</a>) with coauthor Fengqi Fang, a Ph.D. candidate in Business Administration from the Graduate School of Business Administration at TUS. 



The team builds a simple but testable way to check if a country can hit zero net <a href="https://www.earth.com/news/global-trade-is-fueling-a-dangerous-rise-in-methane-emissions/">emissions</a> while its economy keeps expanding.



They also verify the model numerically using real world style parameters so it is not just a chalkboard exercise. 



The paper connects theory to a specific United Nations target on decoupling growth from <a href="https://www.earth.com/news/limiting-global-warming-to-1-5c-is-almost-certainly-out-of-reach/">environmental damage</a>.



<h2 class="wp-block-heading" id="h-zero-emissions-models">Zero emissions models</h2>



First, the authors define a zero-emissions <a href="https://www.un.org/en/climatechange/net-zero-coalition" target="_blank" rel="noreferrer noopener">policy</a> as keeping net pollution at zero at every point in time, by matching abatement to emissions. That requires money, technology, and clear rules to assign who pays.



They run two versions of the economy. 



One is a public goods <a href="https://scholar.harvard.edu/files/stantcheva/files/lecture8.pdf" target="_blank" rel="noreferrer noopener">model</a> where government services like roads or schools lift private production for everyone at once, a standard growth <a href="https://www.journals.uchicago.edu/doi/10.1086/261726" target="_blank" rel="noreferrer noopener">model</a> introduced by Robert Barro in 1990. 



The second adds <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">congestion</a>, where more people share the same public services so the boost per person shrinks.



<h2 class="wp-block-heading" id="h-minimum-income-rule">Minimum income rule</h2>



The key test is whether gross domestic product (<a href="https://data.worldbank.org/indicator/NY.GDP.PCAP.CD" target="_blank" rel="noreferrer noopener">GDP</a>) per capita rises above a minimum income threshold so a country can fully clean what it emits. 



The authors call this the kindergarten rule level of abatement, as in: “clean-up what you make dirty.”



"Following the Kindergarten rule means implementing zero emission technologies in either finite time or asymptotically," noted M. Scott Taylor and William Brock in their related <a href="https://www.nber.org/papers/w9597" target="_blank" rel="noreferrer noopener">study</a>. 



This frame anchors the new threshold concept for developing countries.



<h2 class="wp-block-heading" id="h-aid-supports-clean-income-growth">Aid supports clean income growth</h2>



Many low income governments fund services with official development assistance (<a href="https://www.oecd.org/en/topics/policy-issues/official-development-assistance-oda.html" target="_blank" rel="noreferrer noopener">ODA</a>), so the model lets outside aid pay for both cleaning and public services. 



That design reflects classic work showing how aid aimed at productive public services can shift long run growth.



In related <a href="https://www.sciencedirect.com/science/article/abs/pii/S0304387806000290" target="_blank" rel="noreferrer noopener">theory</a>, flexible labor and aid tied to public capital influence the path of output and welfare. The new paper extends this logic to pollution control that must be paid for every year.



<h2 class="wp-block-heading" id="h-changing-income-threshold">Changing income threshold</h2>



The threshold depends on clean technology, population size, and how much aid is fixed to environmental <a href="https://www.earth.com/news/expanding-oil-and-gas-fields-threaten-global-climate-goals/">uses</a>. Better abatement technology lowers the income bar because each dollar of cleanup removes more pollution.



Population matters differently across the two models. In the public goods case, a larger labor force can raise growth because services scale with the economy, while in the congestion case that scale effect drops out as services get diluted.



<h2 class="wp-block-heading" id="h-taxes-and-zero-emissions-targets">Taxes and zero emissions targets</h2>



The model also looks at tax policy, focusing on a labor income tax that finances services. 



There is a tax rate that maximizes the growth of income per person, and under both models governments can reach the needed income threshold in finite time if they choose that growth maximizing rate.



Public services that complement private capital are the link. When governments tax and spend on those services efficiently, private firms produce more and the <a href="https://www.earth.com/news/climate-action-economies-can-grow-while-cutting-emissions/">economy climbs</a> to the income level that makes full abatement feasible.



"Both models indicate that implementing the zero-emissions policy is compatible with sustainable economic growth," wrote Noda. 



They also show the kindergarten rule threshold is higher with congestion than without it, so crowding of public services slows the crossing.



"We call this threshold the kindergarten rule level of pollution abatement in terms of GDP per capita," wrote Noda. The result gives policymakers a clear income target, not just a slogan about decoupling.



<h2 class="wp-block-heading" id="h-income-growth-and-sdgs">Income growth and SDGs</h2>



Target 8.4 of the Sustainable Development Goals (<a href="https://www.undp.org/sustainable-development-goals" target="_blank" rel="noreferrer noopener">SDGs</a>) asks countries to decouple growth from environmental degradation. 



The authors argue their framework helps explain when that is possible in practice, and how policy levers change the timing.



The UN defines the <a href="https://metadata.un.org/sdg/8.4" target="_blank" rel="noreferrer noopener">target</a> as improving resource efficiency and decoupling growth from environmental harm through 2030. The paper’s threshold view fits that mandate with a concrete yardstick.



<h2 class="wp-block-heading" id="h-why-results-still-matter">Why results still matter</h2>



Earlier <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959652621009112" target="_blank" rel="noreferrer noopener">work</a> in the same research stream focused on developed, innovation-driven economies and showed that zero emissions could be achieved alongside continued growth. 



That study examined whether sustained economic expansion could occur while also maintaining <a href="https://www.earth.com/news/a-net-zero-world-will-require-75-trillion-of-investment-and-1-billion-electric-cars/">zero net pollution emissions</a>.



The new paper shows the same compatibility can hold in aid dependent settings where innovation is not the main growth engine. 



That extension fills a real gap, because many low income countries face tighter fiscal and technological limits.



Build or buy cleaner technology so the threshold falls. Treat tied aid for environmental programs as a growth tool and not just a cost center.



Set tax policy to raise the growth rate of income per person, then sustain it long enough to pass the threshold. Guard against congestion by scaling services with population, so gains are not diluted.



The study is published in <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">The Singapore Economic Review</a>.

Net-zero emissions and rising income levels can both be achieved simultaneously

Balancing cleaner air with rising incomes is not a luxury question for developing countries. It is a real-world, and real-life, policy problem that shapes health, jobs, and the future of their cities. A new study lays out when zero emissions can go hand in hand with steady growth, even when governments rely on foreign aid. Zero emissions and economic growth The work comes from Hideo Noda at the Tokyo University of Science (TUS) with coauthor Fengqi Fang, a Ph.D. candidate in Business Administration from the Graduate School...

People on a fishing boat in the Aegean Sea had an unsettling experience when they noticed square waves creating a chessboard-like pattern all around them. This phenomenon, which quickly drew concern, is an unusual sight in the ocean.



Square waves, also known as a cross sea, are caused by two interacting <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">wave systems</a> traveling at different speeds and trajectories.



This activity was examined by <a href="https://iris.cnr.it/cris/rp/rp12539" target="_blank" rel="noreferrer noopener">Dr. Silvio Davison</a> from the Consiglio Nazionale delle Ricerche (<a href="https://www.cnr.it/" target="_blank" rel="noreferrer noopener">CNR</a>), Istituto di Scienze Marine (<a href="https://www.ismar.cnr.it/web-content/" target="_blank" rel="noreferrer noopener">ISMAR</a>) in Venice, Italy.



<h2 class="wp-block-heading" id="h-understanding-waves-the-basics">Understanding waves - the basics</h2>



Ocean waves are nature’s way of keeping the sea in constant motion. Wind blows across the surface, transferring its energy to the water and creating waves that can travel thousands of miles.



The size and strength of a wave depend on three things: wind speed, how long the wind blows, and the distance it travels over open water (also called fetch). The longer and stronger these forces act, the bigger the waves get.



But not all waves come from the wind. Some, like <a href="https://www.earth.com/news/lake-tsunamis-are-an-emerging-climate-linked-hazard/" target="_blank" rel="noreferrer noopener">tsunamis</a>, are triggered by underwater earthquakes, volcanic eruptions, or landslides.



Then there are tidal waves, which are actually caused by the gravitational pull of the Moon and Sun, not wind or sudden underwater events.



Next we have <a href="https://www.earth.com/news/most-extreme-rogue-wave-recorded-in-the-pacific-ocean/" target="_blank" rel="noreferrer noopener">rogue waves</a>, which are are massive, unpredictable walls of water that seem to appear out of nowhere. 



Rogue waves happen due to complex interactions between ocean currents, wind, and smaller waves merging at just the right moment. Some can reach over 100 feet (30 meters) tall, powerful enough to sink even large ships.



Finally, we have square waves, which is the reason that we're all here right now.



<h2 class="wp-block-heading" id="h-causes-behind-the-grid">Causes behind the grid</h2>



Ocean dynamics can sometimes lead to waves from separate storms merging at sharp angles. When that overlap happens, the surface arranges itself into a repeating, square-like shape.



This can vanish quickly if the wind shifts or if one wave set loses energy. On other occasions, the pattern remains long enough for unwary surfers or vessels to run into trouble.



<a href="https://www.frontiersin.org/journals/marine-science/articles/10.3389/fmars.2022.1002806/full" target="_blank" rel="noreferrer noopener">Researchers</a> have noted that such interactions are more common in open waters with multiple strong weather systems. 



Storm tracks crossing each other can spark chaotic <a href="https://www.earth.com/news/ocean-warming-broke-records-for-450-straight-days/" target="_blank" rel="noreferrer noopener">wave</a> fields that keep everyone on edge.



<h2 class="wp-block-heading" id="h-impact-on-maritime-travel">Impact on maritime travel</h2>



Large <a href="https://www.noaa.gov/jetstream/ocean/rip-currents/rip-current-safety" target="_blank" rel="noreferrer noopener">cross seas</a> can reach heights of nearly 10 feet (3 meters), which is problematic for smaller boats. Faced with perpendicular waves, even a ship may roll unpredictably.



According to the <a href="https://business.esa.int/maritime" target="_blank" rel="noreferrer noopener">European Space Agency</a>, data collected between 1995 and 1999 showed that a large proportion of ship accidents occurred in cross seas. This highlights the threat posed by these shifting forces.



Sailors in these conditions report abrupt lurches and sudden veering. Cargo ships can also face cargo shifts when waves slam from two different angles.



<h2 class="wp-block-heading" id="h-swimmers-should-avoid-square-waves">Swimmers should avoid square waves</h2>



“Swimmers are at risk of being swept away, while boaters can experience navigational problems.” This note of caution from <a href="https://nhess.copernicus.org/articles/21/115/2021/nhess-21-115-2021.html" target="_blank" rel="noreferrer noopener">maritime observers</a> is especially relevant in unpredictable waters.



Opposing currents make it hard for people to fight the pull toward deeper areas. Sections of the sea floor can slope in unexpected ways, which compounds the danger.



Checkered wave events have drawn attention in certain tourist destinations. In places where the phenomenon is less intense, onlookers sometimes gather to watch the spectacle.



A noteworthy location is Île de Ré, near France, where visitors sometimes ascend a lighthouse to see the square pattern. They might not recognize that, out in deeper waters, the same sight can be much more powerful.



<h2 class="wp-block-heading" id="h-precautions-and-advice">Precautions and advice</h2>



Maritime authorities suggest that if a grid-like sea surface is spotted, smaller crafts should stay nearer to shore. Rapid changes can make it tough for seafarers to maneuver.



Some wave specialists recommend altering course to avoid perpendicular wave trains entirely, while others suggest that slowing down can minimize the stress on a vessel’s structure.



Swimmers are urged to exit the water if they notice conflicting currents. Strong swimmers often underestimate lateral pushes that can tire them quickly.



<h2 class="wp-block-heading" id="h-new-technology-to-study-square-waves">New technology to study square waves</h2>



Scientists are examining ways to forecast cross seas more accurately. They hope better models will help shipping routes avoid high-risk zones.



Advanced radar networks are collecting data on wave heights, angles, and directions. These tools might enhance warnings about any abrupt formation of intersecting waves.



Some labs now rely on <a href="https://www.baslerweb.com/en/cameras/basler-stereo-camera/?srsltid=AfmBOoojjrrNlPY291861Z4Kfl0bmQMlssog8JwjcqK_fNtpUb4kFR8Q" target="_blank" rel="noreferrer noopener">stereo camera systems</a> to capture wide surface areas. This technology allows them to document the biggest crests in cross <a href="https://www.earth.com/news/north-atlantic-ocean-has-a-memory-that-lasts-up-to-20-years/" target="_blank" rel="noreferrer noopener">seas</a> with more accuracy.



Digital simulations, like the <a href="https://www.sciencedirect.com/science/article/pii/S246801331730044X" target="_blank" rel="noreferrer noopener">High-Order Spectral method</a>, add another layer of understanding. They reveal how separate swells interact in real time, helping experts refine safety recommendations.



<h2 class="wp-block-heading" id="h-visually-intriguing-yet-dangerous">Visually intriguing yet dangerous </h2>



Cross seas are visually intriguing yet dangerous for unaware travelers. They remind us that the <a href="https://www.earth.com/news/earths-oceans-are-rapidly-changing-colors-matching-climate-predictions/" target="_blank" rel="noreferrer noopener">ocean</a>’s complexity sometimes slips under the radar.



Predicting the square waves calls for close attention to wind shifts and storm paths. Such vigilance may keep mariners and beachgoers out of harm’s way.



Researchers continue to emphasize caution when these wave patterns arise, especially in open oceans.



The study is published in <a href="https://www.frontiersin.org/journals/marine-science/articles/10.3389/fmars.2022.1002806/full" target="_blank" rel="noreferrer noopener">Frontiers in Marine Science</a>.

Square waves: The deadly chessboard pattern threatening sailors

People on a fishing boat in the Aegean Sea had...

Clothes dryers are a standard fixture in the average American home, but they have associated costs. They use a lot of energy, which is expensive and has consequences in terms of carbon dioxide (CO2) emissions into the atmosphere. 



In reality, domestic dryers in the United States consume about 3% of domestic energy use, which is six times more than the consumption by washing machines.



Annually, operating clothes drying appliances in the U.S. costs more than $7 billion and releases the energy equivalent of 27 million tons of CO2. In contrast, drying clothes in the air is a cheap and efficient alternative.



Although American homes have dryers as a standard appliance, this is much less common in other nations. More than 80% of U.S. homes use a dryer, while in South Korea it is less than 30%, in Germany it is slightly over 40% and in the U.K. it is slightly below 60%. 



This imbalance prompted researchers to wonder if Americans might gain from switching to air drying.



<h2 class="wp-block-heading" id="h-the-energy-cost-of-dryers">The energy cost of dryers</h2>



Researchers from the University of Michigan’s School for Environment and Sustainability (<a href="https://seas.umich.edu/">SEAS</a>) wanted to explore the financial and environmental impact of clothes drying. Under the guidance of Shelie Miller, co-director of the UM's Center for Sustainable Systems, the researchers examined different drying methods and their long-term costs.



"In most other places in the world, it's hard to find a <a href="https://www.earth.com/news/clothes-dryers-release-millions-of-microfibers-into-the-air/" target="_blank" rel="noreferrer noopener">clothes dryer</a>," said Zhu Zhu, lead author of the study. "We know dryers consume a lot of energy, so what if you used line drying instead? How much could you save? How many CO2 emissions could you avoid?"



The findings revealed a clear picture: over the lifetime of a dryer, switching entirely to air drying could save households more than $2,100. 



At the same time, this simple change could cut <a href="https://www.earth.com/news/global-carbon-dioxide-emissions-hit-a-record-high-in-2023/" target="_blank" rel="noreferrer noopener">carbon dioxide emissions</a> by over three tons per household. Given the stark contrast in energy use and environmental impact, these results weren’t entirely unexpected.



"We knew that line drying was going to be zero and dryers were going to be a bunch," said Miller.



<h2 class="wp-block-heading" id="h-using-a-mix-of-drying-methods">Using a mix of drying methods</h2>



While some may find it impractical to completely eliminate dryer use, the study found that a combination of line drying and occasional dryer use was the second most cost-effective and eco-friendly option. 



Surprisingly, investing in an energy-efficient dryer didn’t always guarantee savings in the long run.



"We tend to focus on technological improvements, but a lot of the time, behavioral changes can have larger impacts," Miller said. "If we are going to tackle climate change, we have to think about both cultural and technical solutions."



The study also highlighted how the impact of clothes dryers varies by region. In areas where electricity is generated primarily from <a href="https://www.earth.com/news/coal-use-is-not-declining-fast-enough-to-slow-global-warming/" target="_blank" rel="noreferrer noopener">coal</a>, dryers contribute significantly to CO2 emissions in comparison to regions powered by renewable sources like hydroelectric energy.



In some places, switching from a gas dryer to an electric one can either reduce emissions by more than 90% or increase them by over 220%, depending on the energy mix.



<h2 class="wp-block-heading" id="h-small-changes-can-make-a-big-difference">Small changes can make a big difference</h2>



While a transition to <a href="https://www.earth.com/news/refrigeration-will-finally-get-an-upgrade-with-cleaner-energy/" target="_blank" rel="noreferrer noopener">cleaner energy</a> sources would help mitigate the environmental impact of dryers, individuals can take immediate action by adopting more energy-conscious habits. For example, running a dryer at night during off-peak hours can reduce emissions by 8%.



For those who are hesitant about fully embracing air drying, small adjustments can help ease the transition. Some fabrics become stiff when air dried, but a short spin in the dryer - rather than a full cycle - can restore their softness. 



Many also assume they need an outdoor space for air drying, but as long as a room isn’t too humid or cold, air drying works just as well indoors.



"You don't need a big balcony or a huge backyard," Zhu said. "Based on my personal experience, you have more capacity than you imagine."



<h2 class="wp-block-heading" id="h-is-your-dryer-worth-the-energy-cost">Is your dryer worth the energy cost?</h2>



At its core, the study challenges consumers to question whether their habits truly add value to their daily lives.



"A lot of this is asking ourselves whether the consumption we're doing is serving our lives in meaningful ways. The lowest carbon option is always the thing that you don't do," said Miller.



While dryers are convenient, their energy costs and <a href="https://www.earth.com/news/dryers-are-detrimental-to-the-environment-and-human-health/" target="_blank" rel="noreferrer noopener">environmental impacts</a> are hard to ignore.



Whether by embracing full air drying or simply reducing dryer use, small changes can lead to big savings - both for households and for the planet.



The full study was published in the journal <a href="https://linkinghub.elsevier.com/retrieve/pii/S0921344925000916" target="_blank" rel="noreferrer noopener">Resources Conservation and Recycling</a>.

Clothes dryers are not worth the financial and environmental cost

Clothes dryers are a standard fixture in the average American...

Many of us enjoy a banana without a second thought, but new research suggests that rising global temperatures could make this simple pleasure harder to come by.



Researchers have determined that large parts of Latin America and the Caribbean could be unable to sustain banana <a href="https://www.earth.com/news/agroforestry-could-transform-farming-in-the-midwest/" target="_blank" rel="noreferrer noopener">production</a> for export by 2080. The study was led by <a href="https://experts.exeter.ac.uk/22744-dan-bebber" target="_blank" rel="noreferrer noopener">Dan Bebber</a> from the University of Exeter.



<h2 class="wp-block-heading" id="h-shifting-supply-landscape">Shifting supply landscape</h2>



Bananas are a key export crop worth $11 billion. They power the economies of many nations that rely on steady harvests and predictable trade relationships.



These recent projections show that climate change threatens about 60% of current growing regions. Economic setbacks and job losses in these areas could follow if swift action is not taken.



Producers face multiple uncertainties, from rising temperatures to unpredictable rainfall. Some farmers are already noticing shifts in planting schedules and increased difficulties in keeping fields <a href="https://www.earth.com/news/robotic-insects-may-be-the-future-of-farming-and-plant-pollination/" target="_blank" rel="noreferrer noopener">productive</a>.



Experts warn that these changes could create a chain reaction for global markets. This scenario is particularly concerning for people who depend on bananas for both nutrition and income.



Scientists note that shifting temperatures could also allow pests to flourish. This change puts more pressure on growers who have to adapt to new threats.



<h2 class="wp-block-heading" id="h-economic-ripple-effects">Economic ripple effects</h2>



Banana exports are a major source of revenue in certain countries. Without them, families and entire communities would be forced to seek new ways to earn a living.



Traders and distributors also stand to lose if volumes drop or if producers relocate to different areas. Businesses that rely on a consistent supply risk losing profit margins.



Transportation networks near ports highlight how reliant this industry is on accessible shipping. Any disruption in that setup could prolong delivery times and raise costs.



Analysts highlight that this fruit’s supply chain has always balanced on slim margins. A sudden climate-related shortfall can send waves across multiple markets.



Money for new technology often goes to bigger operations first. Smaller farms lack the resources to handle sudden shifts in weather or market demands.



<h2 class="wp-block-heading" id="h-rising-temperatures-hurt-bananas">Rising temperatures hurt bananas</h2>



Rising temperatures are a central factor behind banana production declines. Many varieties cannot thrive when daytime heat moves beyond their comfort zone.



Intense heat can reduce pollination and slow growth, forcing higher water usage and more stress on plants. Some farmers implement irrigation, but that introduces extra costs.



These difficulties have already prompted fears about productivity. Some areas might become completely unsuitable if average temperatures continue to climb.



Researchers have tied these temperature spikes to broader global warming <a href="https://www.ipcc.ch/report/ar6/wg1/" target="_blank" rel="noreferrer noopener">patterns</a>. They say more extreme heat events may appear if <a href="https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emissions" target="_blank" rel="noreferrer noopener">greenhouse gas emissions</a> remain high.



Some producers explore shade-grown systems to reduce scorching, but this method can limit large-scale operations due to space and management <a href="https://www.earth.com/news/mixed-cover-crops-may-be-the-future-of-sustainable-farming/" target="_blank" rel="noreferrer noopener">requirements</a>.



<h2 class="wp-block-heading" id="h-socioeconomic-stumbling-blocks">Socioeconomic stumbling blocks</h2>



Adaptation is not simply a matter of finding new farmland. Many plantations are located in densely populated areas where labor is available.



Moving operations to less populated zones sounds logical, but shipping routes and basic infrastructure remain essential. Building new roads and port facilities is no small feat.



Limited finances often block these developments. Wealthier regions might upgrade quickly, while smaller producers struggle to keep up.



Efforts like training programs could help, but they require financial backing and stable governance. Local workers also need assurance of fair pay and good working conditions.



Community-based projects might ease tensions over land use. These initiatives can support shared resources, but they hinge on cooperative planning.



<h2 class="wp-block-heading" id="h-bananas-adapting-to-temperature-shifts">Bananas adapting to temperature shifts</h2>



One approach involves breeding heat-tolerant bananas. This strategy aims to keep yields stable even in warmer climates.



Irrigation systems play a key role in mitigating dryness. Some regions have turned to drip irrigation and water-saving technology, but these solutions often come with a hefty price tag.



Experts emphasize the importance of preventing disease outbreaks as well. Emerging pathogens can strike when crops are stressed by temperature swings or water scarcity.



“Our findings are a stark reminder that climate change is not just an environmental issue but a direct threat to global food security and livelihoods. Bananas are one of the world's most important fruits, not only for consumers but for millions of workers in producing countries,” said Bebber.



Combining traditional knowledge with modern science could offer practical responses that keep bananas viable in rising temperatures.



Local governments may encourage water management training. This approach helps people learn efficient techniques that preserve scarce resources.



<h2 class="wp-block-heading" id="h-sustainable-farming-and-funding">Sustainable farming and funding</h2>



Some research groups partner with communities to test pilot projects on sustainable <a href="https://www.earth.com/news/disease-resistant-banana-may-change-the-future-of-farming/" target="_blank" rel="noreferrer noopener">farming</a>. The results often show that early planning can ward off major disruptions.



Industry groups are focusing on ways to preserve farmland while cutting emissions. Some growers explore renewable energy options to power equipment.



Alternative financing, such as <a href="https://www.sba.gov/funding-programs/loans/microloans" target="_blank" rel="noreferrer noopener">microloans</a>, can help farmers upgrade equipment. This step ensures that no one is left behind.



The study is published in the journal <a href="https://www.nature.com/articles/s43016-025-01130-1" target="_blank" rel="noreferrer noopener">Nature Food</a>.

Rising temperatures threaten the future of banana farming

Many of us enjoy a banana without a second thought,...

Earth's climate is changing fast, and scientists are racing to understand how plants will respond. As temperatures rise and carbon dioxide levels increase, plants face new challenges and opportunities.



Some may grow larger, while others might struggle to maintain their natural processes. Understanding these shifts is essential for predicting future agricultural yields and ecosystem stability.



Researchers at the MSU-DOE Plant Research Laboratory (<a href="https://prl.natsci.msu.edu" target="_blank" rel="noreferrer noopener">PRL</a>) Sharkey lab are studying how plant metabolism reacts to high light and high CO2 (HLHC) conditions.



The findings reveal that plants photosynthesize more in these conditions, which can result in larger <a href="https://www.earth.com/news/plants-may-stop-absorbing-carbon-if-temperatures-continue-to-rise/" target="_blank" rel="noreferrer noopener">plants</a> and higher crop yields. However, this process comes with a cost - plants also lose carbon, a key component for making food.



These results, published in Scientific Reports, highlight the complexity of plant responses to environmental changes.



<h2 class="wp-block-heading" id="h-the-future-of-plant-metabolism">The future of plant metabolism </h2>



Scientists predict two major environmental shifts will affect plant metabolism. First, atmospheric carbon dioxide levels will continue rising. 



Second, global brightening will alter light conditions, as more solar radiation reaches the Earth's surface than in previous decades.



These <a href="https://www.earth.com/news/natures-climate-solutions-mixed-forests-store-more-carbon/" target="_blank" rel="noreferrer noopener">shifts</a> will impact how plants grow and process carbon. Understanding these effects is crucial for future agricultural and ecological planning.



<h2 class="wp-block-heading" id="h-increasing-photosynthesis-rates">Increasing photosynthesis rates</h2>



“Our work demonstrates that it’s very important to study photosynthesis and the carbon metabolism in plants,” said Yuan Xu, postdoctoral researcher in the <a href="https://bmb.natsci.msu.edu/labs/sharkey-lab/sharkey-lab.aspx" target="_blank" rel="noreferrer noopener">Sharkey lab</a> and first author of the study. 



“Especially when we think about conditions for the future based on predictions. If you want to do bioengineering in the future, to make a plant that can better adapt to these future conditions, you need to focus on these areas.”



The experts found that in future conditions, photosynthesis rates increase, but light respiration rates remain unchanged. This means plants can produce more sucrose and starch, which are vital for their survival and growth.



<h2 class="wp-block-heading" id="h-how-plants-store-carbon">How plants store carbon</h2>



“Most carbon fixed in photosynthesis becomes either starch [to use later] – like putting money in your bank account – or sucrose (table sugar) to use now – like buying an ice cream cone,” said Thomas D. Sharkey, University Distinguished Professor in the PRL. 



“The most surprising observation was that extra carbon at high light and high carbon dioxide went much more to starch (76% increase) rather than sucrose (41% increase). This may help plants become more resilient because they will have extra carbon for growth or defense.”



Larger plants and increased crop yields could result from this higher rate of photosynthesis. However, a challenge remains: plants also lose carbon during the <a href="https://www.earth.com/news/plants-absorb-31-more-co2-than-previously-estimated/" target="_blank" rel="noreferrer noopener">process</a>, reducing the total available food.



<h2 class="wp-block-heading" id="h-resilience-of-future-plants">Resilience of future plants</h2>



During photosynthesis, plants release CO2 through a process called respiration in light (RL). 



The researchers found that RL remains constant under both current and future conditions. Despite increased photosynthesis, the rate at which plants release CO2 through RL does not change.



This suggests that while plants may grow larger, they still lose a steady amount of carbon. Understanding this balance is essential for improving plant resilience in changing environments.



<h2 class="wp-block-heading" id="h-measuring-plant-carbon-loss">Measuring plant carbon loss</h2>



To analyze RL under HLHC conditions, researchers used a unique approach. Traditional methods like the Laisk or Kok techniques only work in low light <a href="https://www.earth.com/news/earths-carbon-sinks-are-being-pushed-to-their-limits/" target="_blank" rel="noreferrer noopener">conditions</a>.



“That’s why this study is unique,” Xu explained. “We used a new approach to measure the RL in the high light condition that cannot be measured using the old method.”



Xu applied a technique known as isotopically nonstationary metabolic flux analysis (INST-MFA). This method, commonly used in bacteria and fungi studies, has rarely been applied to <a href="https://www.earth.com/news/planting-diverse-crops-traps-carbon-and-boosts-soil-health/" target="_blank" rel="noreferrer noopener">plant research</a>.



<h2 class="wp-block-heading" id="h-future-research-directions">Future research directions</h2>



The Sharkey lab plans to continue exploring respiration in light using advanced research techniques. Their goal is to deepen the understanding of how plants take in and release carbon dioxide.



“We know from this study that many things are changed [under future conditions] including photosynthesis, photorespiration and respiration in the light,” Xu said. “This gave a hint for future work.”



The research was funded by the Division of Chemical Sciences, Geosciences, and Biosciences, Office of Basic Energy Sciences at the U.S. Department of Energy.

How future climate conditions will transform plant growth

Earth's climate is changing fast, and scientists are racing to...

The end-Permian mass extinction, 252 million years ago, was devastating to life on Earth. Massive volcanic eruptions unleashed 100,000 billion metric tons of carbon dioxide, triggering a severe climate crisis.



This led to extreme global warming, deoxygenated oceans, and widespread extinction. However, many plants survived, leaving fossil records that help scientists understand a dramatic 10-degree rise in <a href="https://www.earth.com/news/scientists-predict-how-and-when-humans-and-mammals-will-face-extinction/" target="_blank" rel="noreferrer noopener">global temperatures</a>.



“While fossilized spores and pollen of plants from the Early Triassic do not provide strong evidence for a sudden and catastrophic biodiversity loss, both marine and terrestrial animals experienced the most severe mass extinction in Earth’s history,” explained Dr. Maura Brunetti of the <a href="https://www.unige.ch/en/" target="_blank" rel="noreferrer noopener">University of Geneva</a>. 



“Life on Earth had to adjust to repeated changes in climate and the carbon cycle for several million years after the Permian-Triassic Boundary.”



<h2 class="wp-block-heading" id="h-reconstructing-the-ancient-climate">Reconstructing the ancient climate</h2>



The scientists studied five geological stages on either side of the Permian-Triassic Boundary. These included the Permian Wuchiapingian and Changhsingian, the early Triassic Induan and Olenekian, and the middle Triassic Anisian.



Using maps of Earth’s ancient geography and plant fossil data, the researchers identified six major biomes and estimated local climates based on fossil distributions.



The identified biomes ranged from tropical, humid regions to seasonal temperate and desert areas. 



Cold climates featured desert in the tropics and tundra at higher latitudes, while warm <a href="https://www.earth.com/news/public-concern-over-species-extinctions-fades-quickly/" target="_blank" rel="noreferrer noopener">climates</a> had temperate vegetation near the poles and deserts near the equator. Increased carbon dioxide levels led to warmer and wetter conditions.



<h2 class="wp-block-heading" id="h-climate-and-ecosystem-shifts-after-extinction">Climate and ecosystem shifts after extinction</h2>



Using statistical models, the scientists compared plant fossil records with simulated biomes under different climate conditions. Their findings revealed dramatic shifts in ecosystems at the Permian-Triassic Boundary.



Before the extinction, the Permian had a colder climate. The early Triassic Induan period showed <a href="https://www.earth.com/news/how-forests-rose-again-after-the-planets-most-extreme-extinction/" target="_blank" rel="noreferrer noopener">unstable conditions</a> that scientists could not clearly classify. 



This uncertainty may be due to sampling biases, poor fossil preservation, or short-term climate variations. More fossil data is needed for clarity.



Later Triassic periods saw significantly warmer conditions. The Olenekian and Anisian stabilized at temperatures 10 degrees higher than the Permian.



<h2 class="wp-block-heading" id="h-a-hotter-future">A hotter future</h2>



“This transition from the colder climatic state to the hotter state is marked by an increase of approximately 10⁰C in the mean global surface air <a href="https://www.earth.com/news/half-of-the-worlds-heliconia-species-are-at-risk-of-extinction/" target="_blank" rel="noreferrer noopener">temperature</a> and an intensification of the water cycle,” said Dr. Brunetti.



“Tropical everwet and summerwet biomes emerged in the tropics, replacing predominantly desertic landscapes. Meanwhile, the warm-cool temperate biome shifted towards polar regions, leading to the complete disappearance of tundra ecosystems.”



Dr. Brunetti noted that the shift in vegetation cover can be linked to tipping mechanisms between climatic steady states, providing a potential framework for understanding the transition between Permian and Triassic.



“This framework can be used to understand tipping behavior in the climate system in response to the present-day CO2 increase. If this increase continues at the same rate, we will reach the level of emissions that caused the Permian-Triassic mass extinction in around 2,700 years — a much faster timescale than the Permian-Triassic Boundary emissions.”



<h2 class="wp-block-heading" id="h-uncertainties-and-future-research">Uncertainties and future research</h2>



More data and refined models are necessary for clearer conclusions. “The comparison between simulated biomes and the dataset is influenced by uncertainties, arising from paleogeographic reconstructions and the classification of fossil assemblages into biomes,” said Dr. Brunetti.



“Furthermore, our climate modeling setup relies on offline coupling between models — the vegetation model uses the final outputs of the climatic model for biome reconstruction. This could be enhanced using a dynamic vegetation model.”



The Permian-Triassic extinction reshaped life on <a href="https://www.earth.com/news/saving-earths-most-endangered-plants-from-extinction-proving-difficult-botanic-gardens/" target="_blank" rel="noreferrer noopener">Earth</a>. Studying its causes and consequences may provide valuable insights into the ongoing climate crisis.



<h2 class="wp-block-heading" id="h-climate-lessons-from-past-extinctions">Climate lessons from past extinctions</h2>



The Permian-Triassic extinction reshaped the planet, erasing entire ecosystems and paving the way for new ones. 



By studying how life responded to these changes, scientists can better predict how today’s ecosystems will react to rising temperatures and shifting climate patterns.



Understanding the past is crucial for preparing for the future. If history is any indication, life on Earth will survive - but whether human civilization can adapt as effectively remains an open question.



The study is published in the journal <a href="https://www.frontiersin.org/journals/earth-science/articles/10.3389/feart.2025.1520846/full" target="_blank" rel="noreferrer noopener">Frontiers in Earth Science</a>.

Climate chaos: The mass extinction that reshaped life on Earth

The end-Permian mass extinction, 252 million years ago, was devastating...

A new study has found that, contrary to previous claims, the ocean is not a significant source of microplastics to the atmosphere, but rather a major sink.&nbsp;



The research team used a global chemical transport model to evaluate how tiny plastic particles, known as microplastics, move around the world. 



The finding challenges past assumptions about the ocean’s role in releasing plastic fragments into the air.



<h2 class="wp-block-heading" id="h-the-journey-of-airborne-microplastics-nbsp">The journey of airborne microplastics&nbsp;</h2>



Plastic debris in dust form is increasingly recognized as a worldwide contaminant. <a href="https://www.earth.com/news/microplastics-in-the-brain-alarming-new-details-revealed/" target="_blank" rel="noreferrer noopener">Microplastics</a> (particles less than 5 mm in diameter) have been detected in soils, freshwater, the ocean, and even in the air that we breathe.&nbsp;



Scientists warn that microscopic plastic bits pose risks for human health, since they can easily enter the respiratory system and the bloodstream.&nbsp;



Once airborne, these tiny pieces can travel large distances and eventually settle in remote or sensitive regions, harming wildlife and potentially impacting human populations.



But how do these particles enter the atmosphere in the first place? The planet’s primary sources of microplastics are typically found on land, from everyday materials such as vehicle tires shedding particles on roads, or synthetic clothing fibers washed out in domestic wastewater.&nbsp;



However, earlier models had suggested that there might be an additional large source at sea. Microplastics often accumulate in the <a href="https://www.earth.com/news/microplastics-pose-a-greater-threat-to-some-ocean-animals/" target="_blank" rel="noreferrer noopener">oceans</a>, carried there by rivers and other waterways. Then, once present in the marine environment, it was believed that they could be lofted into the air by sea spray or wind-driven wave action.



<h2 class="wp-block-heading" id="h-what-is-the-ocean-s-contribution">What is the ocean's contribution?</h2>



Prior reports pointing to a large marine source relied on an inverse modeling technique. That method uses atmospheric measurements of particular substances and attempts to infer their origin by matching observed concentrations with predicted distributions.&nbsp;



Applied to microplastics, inverse modeling suggested the ocean might contribute hundreds of millions - or even billions - of kilograms of these fragments to the air each year.



Such massive figures were then tested experimentally, with scientists using wave tanks and other controlled setups to see how vigorously wave action or bursting bubbles could transfer plastics from the water surface into the atmosphere.&nbsp;



Those studies, however, hinted that only tens or hundreds of thousands of kilograms of plastic might plausibly be introduced into the air - orders of magnitude smaller than the figures derived from inverse modeling.



<h2 class="wp-block-heading" id="h-a-global-chemical-transport-model">A global chemical transport model</h2>



In an effort to reconcile these contradictory outcomes, a group led by researchers at the <a href="https://mpimet.mpg.de/en/homepage" target="_blank" rel="noreferrer noopener">Max Planck Institute for Meteorology</a> (MPI-M) ran a global chemical transport model. This computer model simulates the movement of substances, such as microplastic particles, through the atmosphere.&nbsp;



By prescribing a minor oceanic emission of microplastics - consistent with the low estimates from laboratory work - they were able to predict how microplastic concentrations should appear in the air at various locations around the globe.



The results aligned well with real-world measurements. Based on the model, the ocean in fact took up some of these airborne particles instead of emitting them in large quantities.&nbsp;



The scientists learned that rather than being a source, the ocean appeared to be a sink, in which 15 percent of all airborne microplastics are deposited.&nbsp;



In other words, waves, spray, and wind may occasionally lift small amounts of plastic out of the sea, but far more of the material is settling onto the water rather than emanating from it.



<h2 class="wp-block-heading" id="h-how-airborne-microplastics-travel">How airborne microplastics travel</h2>



The study also uncovered the significant influence of particle size on how microplastics travel. Larger plastic fragments drop out of the atmosphere relatively quickly, often landing in coastal areas or not far from their point of emission.&nbsp;



By contrast, smaller particles can remain suspended for up to a year. That extended flight time allows them to cross entire oceans or continents and reach distant regions such as the <a href="https://www.earth.com/news/citizen-scientists-uncover-microplastics-in-the-remote-arctic/" target="_blank" rel="noreferrer noopener">Arctic</a>, where they land on ice or snow.



These discoveries highlight the global character of plastic contamination, showing that microplastic dust can be widespread in places typically considered pristine.&nbsp;



They also clarify that stopping microplastic pollution at its land-based sources may be the most efficient approach, as the ocean itself is neither the greatest emitter nor the root cause.



<h2 class="wp-block-heading" id="h-a-roadmap-for-pollution-reduction">A roadmap for pollution reduction</h2>



Given that airborne microplastics reach faraway corners of the planet, the research team’s results have immediate practical value. Any broad plan to cut plastic pollution should focus on terrestrial origins: tire wear on roads, textiles shedding fibers, and insufficiently treated wastewater.&nbsp;



Additionally, lessening single-use plastics and improving waste management at landfills can help limit microplastics before they disperse into the environment.



These findings show that ocean waters, already burdened by plastic accumulations, are predominantly sinks - taking in plastic particles from the air. They also emphasize that microplastics do not stay put in the environment: large ones settle nearby, while smaller ones can travel global distances.&nbsp;



Future models aimed at <a href="https://www.earth.com/news/plastic-pollution-is-changing-the-entire-earth-system/" target="_blank" rel="noreferrer noopener">plastic pollution</a> will need to consider these dynamics in more detail, particularly when mapping out strategies to protect vulnerable ecosystems, reduce human exposure, and maintain cleaner oceans.



By settling this debate over whether the ocean is more of a source or a sink, scientists can now direct their attention to mitigating the true origins of airborne microplastics, thus improving targeted policies to help address this pressing environmental concern.



The study is published in the journal <a href="https://dx.doi.org/10.1038/s41612-025-00914-3" target="_blank" rel="noreferrer noopener">npj Climate and Atmospheric Science</a>.

Airborne microplastics: Where they come from and where they go

A new study has found that, contrary to previous claims,...

Pure,Michigan,-,Marquette,Landscape,Photos

Rock formations can appear to be static, silent observers of the passage of time. But under their apparently immovable form, they are in a state of constant change, molded by immense natural forces.



Mountains form over millions of years, as tectonic plates crush into each other. Glaciers, persistent rain, and constant winds, on the other hand, slowly erode the mountains away.



These forces shape the landscapes we observe today, but there is one often-forgotten factor that is important in this process: the rock's strength.



To learn more about this aspect of landscape evolution, scientists from the <a href="https://www.utm.utoronto.ca/" target="_blank" rel="noreferrer noopener">University of Toronto Mississauga</a> undertook a detailed investigation of rock strengths and how these affect erosion rates.



Their work, which appeared recently in Science Advances, uncovered a surprising revelation - rock type alone can result in a whopping 20-fold contrast in erosion rates. 



This is something that has been underappreciated in past geological models.



The researchers centered on a 200-kilometer section of the southeastern coast of Brazil, an area with a stable climate and little tectonic activity, which made it a perfect natural lab.



By separating rock strength from the other factors, they obtained new knowledge about how landscapes change through time.



<h2 class="wp-block-heading" id="h-measuring-erosion-and-rock-strength">Measuring erosion and rock strength</h2>



To determine how quickly different types of rock erode, the scientists took a multi-faceted approach, analyzing both <a href="https://www.earth.com/news/soil-erosion-rates-have-exploded-in-the-midwestern-us/" target="_blank" rel="noreferrer noopener">erosion rates</a> and the physical properties of the rocks themselves.



They studied river sediments to track landscape changes over time, and provided a clearer picture of long-term geological transformations.



A key part of their research involved measuring the concentration of beryllium-10, a rare radioactive isotope that forms when cosmic rays strike Earth’s surface. 



This isotope acts as a natural geological clock - similar to how tree rings reveal a tree’s age - which allows scientists to estimate how long a rock has been exposed to erosion.



The more beryllium-10 present, the longer the rock has remained at the surface.



The team also used a specialized tool called a <a href="https://www.earth.com/news/stone-tool-flint-discovery-challenges-theory-of-human-cultural-evolution/" target="_blank" rel="noreferrer noopener">Schmidt hammer</a> to measure rock strength. This device works by striking the rock with a spring-loaded mass and recording the force of its rebound. 



Stronger rocks produce a higher rebound, much like a basketball bouncing higher on a hard court than on soft grass. 



<h2 class="wp-block-heading" id="h-role-of-rock-type-in-erosion">Role of rock type in erosion</h2>



"The hypothesis is that, if rock strength matters, we ought to see a correlation between rock strength and erosion rates," explained Lindsay Schoenbohm, a professor of Earth sciences at the University of Toronto Mississauga, and the study’s lead researcher.



"Harder rocks should equal slower erosion rates," she noted.



The study confirmed this pattern, showing that rock type plays a crucial role in shaping landscapes. Softer rocks erode quickly, influencing the formation of valleys, <a href="https://www.earth.com/news/human-activities-threaten-rivers-far-more-than-climate-change/" target="_blank" rel="noreferrer noopener">river systems</a>, and even mountain structures.



<h2 class="wp-block-heading" id="h-database-named-thor">Database named "Thor"</h2>



To make their findings widely accessible, the researchers compiled their rock strength data into a publicly available database, nicknamed "Thor."



Launched in December, this resource offers valuable data for scientists studying climate, <a href="https://www.earth.com/news/plate-tectonics-active-beginning/" target="_blank" rel="noreferrer noopener">tectonics</a>, and landscape evolution.



"We created it for people like us, initially - people who are looking at erosion rates in landscapes," one scientist noted. "But I think the applications could be extremely broad."



By emphasizing the role of rock strength in shaping landscapes, this research lays the foundation for future studies. 



Scientists can now better predict how <a href="https://www.earth.com/news/animals-secretly-reshape-landscapes-in-powerful-ways/" target="_blank" rel="noreferrer noopener">landscapes</a> will evolve by factoring in not only external forces like climate and tectonics but also the physical properties of the rocks themselves.



<h2 class="wp-block-heading" id="h-rock-strength-and-land-management">Rock strength and land management</h2>



Understanding how rock strength influences erosion isn’t just about reconstructing the past - it has real-world implications for the future.



As climate change accelerates weathering processes, areas with softer rocks may undergo more rapid landscape transformations, increasing sediment flow into rivers and coastal ecosystems. 



This, in turn, can affect water quality, agriculture, and infrastructure stability.



The findings could also help guide land management and conservation efforts. By identifying regions with highly erodible rock types, policymakers can develop strategies to prevent excessive soil loss and protect ecosystems. 



The Thor database offers a valuable tool for scientists and environmental planners to anticipate landscape changes and make informed decisions about land use and conservation.



With these insights, researchers are not only refining our understanding of Earth’s ever-changing landscapes but also offering practical solutions for managing and protecting them.



The full study was published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.adr2610" target="_blank" rel="noreferrer noopener">Science Advances</a>.

The world is changing, and so is the climate. Sudden temperature drops, unexpected frosts, and shifting weather patterns challenge ecosystems in many ways. 



For plants, these changes are especially harsh. Unlike animals, they cannot migrate, seek shelter, or generate body heat in cold weather. Instead, they rely on internal <a href="https://www.earth.com/news/climate-warming-alters-plant-germination-and-disrupts-ecosystem-balance/" target="_blank" rel="noreferrer noopener">adaptations to survive</a>.



Varvara Dikaya at <a href="https://www.umu.se/en/" target="_blank" rel="noreferrer noopener">Umeå University</a> explored this challenge in her doctoral research. She studied a protein which plays a key role in plant adaptation to low temperatures.



The findings reveal that this protein participates in multiple signaling pathways, enabling plants to survive harsh conditions.



<h2 class="wp-block-heading" id="h-cold-response-strategies-of-plants">Cold response strategies of plants </h2>



Unlike animals, <a href="https://www.earth.com/news/shaded-plants-capture-light-beyond-the-visible-spectrum/" target="_blank" rel="noreferrer noopener">plants</a> cannot seek warmth or migrate. Their survival depends on internal mechanisms that adjust to temperature shifts. 



Past research focused on molecules like amino acids and sugars, which help prevent freezing. Scientists also studied core temperature-response mechanisms, but many crucial components remained unknown.



Dikaya’s <a href="http://umu.diva-portal.org/smash/record.jsf?pid=diva2:1933796" target="_blank" rel="noreferrer noopener">research</a> uncovers a missing piece of this puzzle - RNA splicing. This process determines which proteins are produced in plant cells, directly impacting cold response strategies.



<h2 class="wp-block-heading" id="h-understanding-rna-splicing-the-basics">Understanding RNA splicing - the basics</h2>



<a href="https://www.earth.com/news/human-cells-communicate-with-each-other-through-rna/" target="_blank" rel="noreferrer noopener">RNA</a> splicing is like an editing process for your genes, making sure your cells get the right instructions to build proteins. 



When a gene gets copied into RNA, it includes extra sections called introns that don’t actually code for anything useful. 



Before the <a href="https://www.earth.com/news/rna-world-unraveling-mysteries-life-origin/" target="_blank" rel="noreferrer noopener">RNA can do its job</a>, the cell cuts out these introns and stitches together the remaining pieces, called exons. 



This process turns a raw RNA transcript into a polished, ready-to-go messenger RNA (mRNA) that cells can use to make proteins.



Sometimes, cells splice RNA in different ways, mixing and matching exons to produce multiple proteins from the same gene. 



This alternative splicing is why our relatively small number of genes can make such a huge range of proteins. When splicing goes wrong, though, it can lead to diseases like cancer and genetic disorders.



<h2 class="wp-block-heading" id="h-the-role-of-splicing">The role of splicing </h2>



"Splicing acts as a central hub controlling the information flow from DNA to RNA, defining which proteins are synthesized from a certain gene," explained Dikaya, who is a doctoral student in the Department of Plant Physiology at Umeå University and <a href="https://www.upsc.se" target="_blank" rel="noreferrer noopener">Umeå Plant Science Center</a>.



Her research focused on PORCUPINE, a protein discovered when scientists observed that plants with a mutation in this gene became unusually cold-sensitive. The mutation's spiky shoot tips inspired the name.



<h2 class="wp-block-heading" id="h-impact-of-temperature-drops">Impact of temperature drops</h2>



"The PORCUPINE mutant appears normal under ambient temperature conditions but cannot develop properly in the case of even a mild temperature drop," the team noted.



"Already at 16 degrees, the mutant grows shorter roots with increased root hair density and much smaller rosettes than normal. This is very special,."



Dikaya’s work reveals that cold temperatures trigger an increase in PORCUPINE RNA in cells. This suggests that the plant produces more of this protein to cope with the stress. 



However, PORCUPINE is not just a passive responder. It actively participates in the spliceosome, a complex that processes RNA before it transforms into proteins.



<h2 class="wp-block-heading" id="h-key-player-in-rna-processing">Key player in RNA processing</h2>



PORCUPINE is not just a responder to cold; it is an active participant in RNA processing. 



This protein is part of the spliceosome, a complex molecular machine that modifies RNA before it is translated into proteins. Without proper RNA splicing, plants cannot produce the proteins they need to survive.



By studying PORCUPINE’s role in the spliceosome, Dikaya and her team discovered that it influences multiple genetic pathways. 



Some of these pathways control how plants sense and react to cold temperature shifts. Others regulate growth patterns that determine whether a <a href="https://www.earth.com/news/predicting-how-climate-change-will-alter-plant-growth-cycles/" target="_blank" rel="noreferrer noopener">plant</a> can withstand stress.



<h2 class="wp-block-heading" id="h-a-network-of-cold-responses">A network of cold responses</h2>



Dikaya and her colleagues identified several genes controlled by PORCUPINE, all of which influence how plants respond to temperature changes. Her research highlights how intricate these responses are, involving multiple overlapping pathways.



"Our findings show the complexity of the cold response in plants. It is important to understand all aspects and identify fundamental mechanisms that could be applied later on in a practical manner," Dikaya noted.



"Such knowledge will be essential to create more resilient <a href="https://www.earth.com/news/bioelectric-future-harnessing-the-natural-energy-of-plants/" target="_blank" rel="noreferrer noopener">plants</a> capable of withstanding environmental challenges in the future, even though it is still a long way to go."



Her work provides a deeper understanding of how plants adjust to fluctuating temperatures. This knowledge could pave the way for crops that can better withstand future climate uncertainties.



<h2 class="wp-block-heading" id="h-future-of-cold-resistant-plants">Future of cold-resistant plants</h2>



The challenges of climate change are not going away, and neither is the need for <a href="https://www.earth.com/news/phantom-nutrient-the-secret-force-that-fuels-plant-growth/" target="_blank" rel="noreferrer noopener">resilient crops</a>. 



If researchers can harness the knowledge gained from studies like Dikaya’s, they may be able to develop plant varieties that thrive despite temperature fluctuations.



Although there is still much to learn, this research brings us one step closer to understanding the intricate mechanisms that allow plants to survive. In the years ahead, discoveries like this could reshape agriculture and help ensure food security in a changing world.

Plants have an amazing ability to 'rewire' themselves to survive winter

The world is changing, and so is the climate. Sudden...

A recent study confirmed that the Antarctic ozone layer is currently healing, as a result of global efforts to reduce ozone-depleting substances.&nbsp;



The study demonstrates that joint international measures - in particular, the phase-out of chemicals that damage the ozone layer - have led to a meaningful restoration of this critical atmospheric shield.



Scientists, including the <a href="https://www.mit.edu/" target="_blank" rel="noreferrer noopener">MIT</a> team that led the current study, have previously detected indications of <a href="https://www.earth.com/news/burning-up-of-satellites-severely-harms-ozone-recovery/" target="_blank" rel="noreferrer noopener">ozone recovery</a>.



However, this new study is the first to provide strong statistical evidence that the improvement is primarily driven by the reduction of ozone-depleting substances, rather than factors like natural weather fluctuations or rising greenhouse gas levels in the stratosphere.



<h2 class="wp-block-heading" id="h-recovery-of-the-ozone-hole">Recovery of the ozone hole</h2>



“There’s been a lot of qualitative evidence showing that the Antarctic ozone hole is getting better. This is really the first study that has quantified confidence in the recovery of the ozone hole,” said study co-author Susan Solomon, a professor of environmental studies and chemistry at MIT.&nbsp;



“The conclusion is, with 95 percent confidence, it is recovering. Which is awesome. And it shows we can actually solve environmental problems.”



Solomon worked on this project with lead author and graduate student Peidong Wang and contributors from multiple other research institutions.&nbsp;



The team’s findings offer strong support for the success of international policy interventions - specifically the <a href="https://www.earth.com/news/1987-ozone-treaty-had-an-unexpected-benefit-for-the-environment/" target="_blank" rel="noreferrer noopener">Montreal Protocol</a>, which curbed the production of ozone-depleting substances such as chlorofluorocarbons (CFCs).



<h2 class="wp-block-heading" id="h-seasonal-ozone-hole-over-antarctica-nbsp">Seasonal ozone hole over Antarctica&nbsp;</h2>



Within the Earth’s stratosphere, ozone is a naturally occurring gas that acts as a sort of sunscreen, protecting the planet from the sun’s harmful ultraviolet radiation.&nbsp;



However, in 1985, scientists discovered that a seasonal “hole” in the ozone layer developed over Antarctica each austral spring - letting in greater quantities of dangerous UV rays.&nbsp;



By 1986, Solomon, then a scientist at the <a href="https://www.noaa.gov/" target="_blank" rel="noreferrer noopener">National Oceanic and Atmospheric Administration</a> (NOAA), led expeditions that identified CFCs as the chief culprit in stratospheric ozone loss. The Montreal Protocol, enacted in 1987, aimed to gradually eliminate these chemicals worldwide.



<h2 class="wp-block-heading" id="h-natural-and-human-caused-changes-nbsp">Natural and human-caused changes&nbsp;</h2>



“While detecting a statistically significant increase in ozone is relatively straightforward, attributing these changes to specific forcings is more challenging,” Wang said.&nbsp;



In past studies, although ozone levels in the Antarctic region seemed to be improving, scientists struggled to confirm just how much of that recovery was driven by reductions in CFCs as opposed to natural weather variability - such as <a href="https://www.earth.com/news/el-nino-climate-shifts-date-back-250-million-years/" target="_blank" rel="noreferrer noopener">El Niño</a>, La Niña, or the polar vortex - or the effects of rising greenhouse gases.



To tackle these uncertainties, the researchers adopted a “fingerprinting” method, originally developed by Nobel Prize-winning scientist Klaus Hasselmann for distinguishing the impacts of human-caused climate change from natural fluctuations in the climate system.&nbsp;



The MIT-led team adapted this fingerprinting to separate human-driven ozone gains from other atmospheric noise.



They began by running climate simulations for various scenarios: a hypothetical world where greenhouse gases did not rise, a world where ozone-depleting substances were not phased out, and other alternative pathways.&nbsp;



In these virtual settings, they examined how ozone levels would shift, both over time and with seasonal changes. By comparing these model outcomes, the scientists identified a characteristic signal of ozone healing - an unmistakable pattern that occurred only when CFCs were curbed.



<h2 class="wp-block-heading" id="h-distinct-fingerprint-in-the-data">Distinct “fingerprint” in the data</h2>



The researchers then combed through 15 years’ worth of satellite observations of the Antarctic ozone hole. 



Step by step, they tested whether the actual data exhibited the predicted pattern of recovery - a fingerprint tied specifically to the global phase-out of CFCs. The match was impressively strong.



“After 15 years of observational records, we see this signal to noise with 95 percent confidence, suggesting there’s only a very small chance that the observed pattern similarity can be explained by variability noise,” Wang said.&nbsp;



“This gives us confidence in the fingerprint. It also gives us confidence that we can solve environmental problems. What we can learn from ozone studies is how different countries can swiftly follow these treaties to decrease emissions.”



<h2 class="wp-block-heading" id="h-lessons-from-the-healing-ozone-hole">Lessons from the healing ozone hole</h2>



The study’s findings imply that if these trends persist, the Antarctic ozone hole could eventually close for good.&nbsp;



“By something like 2035, we might see a year when there’s no ozone hole depletion at all in the Antarctic. And that will be very exciting for me,” Wang said. “And some of you will see the ozone hole go away completely in your lifetimes. And people did that.”



From a broader perspective, the ozone hole’s gradual healing stands as a success story for international cooperation on an environmental crisis.&nbsp;



At the height of <a href="https://www.earth.com/news/use-of-banned-ozone-depleting-chemicals-is-increasing/" target="_blank" rel="noreferrer noopener">CFC use</a>, aerosol propellants, refrigerants, and other industrial processes threatened to erode Earth’s UV shield to dangerous levels. Rapid science-based policymaking in the form of the Montreal Protocol turned the tide, demonstrating that even large-scale environmental challenges can be confronted.



The researchers consider this a timely lesson for today’s leaders, as the world grapples with complex ecological problems, including climate change.&nbsp;



By illustrating how robust, evidence-based treaties can drive positive, global-scale outcomes, the current work highlights both the vulnerability of Earth’s atmosphere and the power of coordinated human action.



The study is published in the journal <a href="http://dx.doi.org/10.1038/s41586-025-08640-9" target="_blank" rel="noreferrer noopener">Nature</a>.

The ozone layer is healing - will the hole disappear for good?

A recent study confirmed that the Antarctic ozone layer is...

The fashion industry has long operated on a system of take, make, and waste, where resources are extracted, turned into garments, and eventually discarded - often far too soon.



Clothing is produced at a rapid pace, sold in mass quantities, worn for a short period, and frequently tossed aside, which contributes to the growing problem of textile waste.



Many of these discarded garments end up in landfills or incinerators, adding to pollution and resource depletion.



This linear approach is not just wasteful - it’s a major environmental burden. The fashion industry is responsible for about 10% of global greenhouse gas emissions, making it one of the most polluting industries in the world.



The heavy reliance on raw materials, energy-intensive production, and short product lifecycles all contribute to its massive footprint.



Now, a new guide is offering a practical way forward, helping brands transition to a circular design model that prioritizes sustainability, longevity, and waste reduction.



<h2 class="wp-block-heading" id="h-roadmap-to-circular-fashion">Roadmap to circular fashion</h2>



Scientists at <a href="https://www.rmit.edu.au/" target="_blank" rel="noreferrer noopener">RMIT University</a> have partnered with brands to create <a href="https://refashioning.org/download/" target="_blank" rel="noreferrer noopener">Refashioning: Accelerating Circular Product Design at Scale</a>. 



This is a guide that is aimed at eliminating wasteful design practices and promoting durable fashion.



The goal is to help brands transition from linear production models to circular design - where products are created with reuse, <a href="https://www.earth.com/news/global-recycling-day-creating-a-healthier-planet-for-all/" target="_blank" rel="noreferrer noopener">recycling</a>, and longevity in mind.



Professor Alice Payne, project lead and Dean of the University’s school of fashion and textiles, explained that the guide challenges traditional design thinking and offers practical steps for businesses looking to make a change.



“This guide provides a systematic approach to implementing circular <a href="https://www.earth.com/news/people-were-already-making-clothing-120000-years-ago/" target="_blank" rel="noreferrer noopener">clothing</a> design in a way that all organizations can implement, regardless of their size,” Payne explained.



“Based on extensive research with the industry, we’ve created practical steps businesses can take to improve the circularity of their outputs," she added. 



"Although other circular design guides are available, Refashioning is unique in providing a systematic methodology that enables designers to both slow the flow and close the loop.”



<h2 class="wp-block-heading" id="h-why-circular-fashion-is-the-future">Why circular fashion is the future</h2>



Most fashion brands still rely on a production system that encourages short-lived clothing. 



Products are made quickly and cheaply, with little thought about what happens to them once consumers are finished wearing them.



A circular approach changes that. It considers key factors early in the design process - material choices, product durability, intended use, and what happens to the product at the end of its useful life.



By making these decisions upfront, brands can create garments that last longer and can be repaired, reused, or recycled rather than sent to landfills.



<h2 class="wp-block-heading" id="h-industry-and-government-collaboration">Industry and government collaboration</h2>



The project was funded by Sustainability Victoria and developed in partnership with Country Road Group brands and two independent circular design experts, Courtney Holm and Julie Boulton.



Sustainability Victoria’s CEO, Matt Genever, highlighted the importance of collaboration between industry, government, and researchers to address <a href="https://www.earth.com/news/the-dark-side-of-donating-clothes-to-charity/" target="_blank" rel="noreferrer noopener">textile waste</a>.



“It’s an example of how effective cross-sector collaboration can generate impactful results in the transition to a circular economy,” he said.



“By fostering partnerships across sectors, Sustainability Victoria enables meaningful change that moves beyond theory and into real, actionable solutions.”



<h2 class="wp-block-heading" id="h-testing-circular-fashion-in-the-real-world">Testing circular fashion in the real world</h2>



One of the key strengths of the guide is that it was tested on real products before being finalized. 



Over the course of a year, eight product and design teams from four brands - Country Road, Trenery, Witchery, and Politix - applied the guidelines in a commercial setting.



This hands-on approach ensured the guide was practical and adaptable for real-world use.



Erika Martin, Head of Sustainability at Country Road Group, explained how working on the guide has helped unify their approach to circular design.



“This project delivered a clear vision for circular design, and leveraged the expertise in the industry, academia and our own business,” she said.



“The opportunity to help create guidelines based on real life feedback and challenges and not just academic theory was a key driver for our involvement, alongside our commitment to building a better future.”



<h2 class="wp-block-heading" id="h-shift-towards-a-sustainable-future">Shift towards a sustainable future</h2>



With the <a href="https://www.earth.com/news/eco-friendly-vegan-leather-could-transform-the-fashion-industry/" target="_blank" rel="noreferrer noopener">fashion industry</a> under increasing pressure to reduce its <a href="https://www.earth.com/news/why-fast-fashion-jeans-bad-for-environment/" target="_blank" rel="noreferrer noopener">environmental impact</a>, practical tools like Refashioning offer businesses a clear way to take action. 



By rethinking how clothes are designed from the start, brands can reduce waste, lower emissions, and contribute to a more sustainable future.



The shift to circular design won’t happen overnight. But with collaboration, research, and practical steps, the industry is moving in the right direction - one product at a time.

Trends: How fashion brands are cutting waste and extending product lifespan

The fashion industry has long operated on a system of...

Coastal cities worldwide are confronted with surging waters that threaten properties, infrastructures, and entire regional economies. People living in these areas face new risks every year, making it vital to understand how sea level rise affects both local communities and global markets.



Many experts now point to rising sea levels as a major financial risk. A recent study indicates that losses for global coastal cities could reach well over $3 trillion by the end of this century as coastal cities grapple with flooding and erosion. 



<h2 class="wp-block-heading" id="h-studying-sea-level-rise">Studying sea level rise</h2>



This analysis stems from a team that investigated the potential financial repercussions under a high emissions scenario across 271 global regions.



This project involved Ignasi Cortés Arbués, Theodoros Chatzivasileiadis, Tatiana Filatova, and their team. 



Through a careful evaluation of 155 flooding events in Europe between 1995 and 2016, the researchers uncovered patterns of how sea level rise might affect different parts of the continent, especially <a href="https://www.earth.com/news/coastal-cities-are-increasingly-vulnerable-to-hurricanes/" target="_blank" rel="noreferrer noopener">those close to the shore</a>.



<h2 class="wp-block-heading" id="h-climate-factors-driving-the-tide">Climate factors driving the tide</h2>



Rising sea levels often trace back to the rapid melting of polar ice caps and glaciers, along with the expansion of warming seawater. 



Scientific data shows that the rate of sea level rise has been <a href="https://www.earth.com/news/hawaii-is-sinking-faster-than-expected/" target="_blank" rel="noreferrer noopener">accelerating in recent years</a>. One of the most concerning elements is that the momentum behind this process could make it difficult to halt, unless overall temperatures stop climbing.



<h2 class="wp-block-heading" id="h-projected-impact-on-european-regions">Projected impact on European regions</h2>



Analysts noted serious risks for areas near the coast. The study found an estimated 872 billion Euros in combined economic losses for the UK and EU by 2100 under a high emissions scenario, contrasting sharply with a hypothetical situation where sea levels remain stable. 



Coastal regions like Veneto and Emilia-Romagna in Italy and Zachodniopomorskie in Poland may see GDP reductions of up to 21% by 2100. 



Some areas around the Baltic Sea, the Belgian coast, parts of western France, and Greece might also experience significant setbacks.



Researchers noticed that inland locations, including regions in Germany, Austria, and Hungary, could potentially see economic increases of up to 1% of regional GDP by 2100. 



Their assessment suggests that production may move away from coastal areas prone to frequent floods and toward these safer regions, helping local industries thrive in places less <a href="https://www.earth.com/news/major-coastal-cities-around-the-world-could-disappear-under-rising-seas-by-2100/" target="_blank" rel="noreferrer noopener">exposed to rising seas</a>.



<h2 class="wp-block-heading" id="h-combating-sea-level-rise-with-investment">Combating sea level rise with investment</h2>



Another part of the study involved looking at how focused funding in economic sectors such as logistics, construction, and public services might ease some of the damage. 



The authors saw limited effects on the broader UK and EU economies, yet certain spots could experience modest relief at relatively low cost. 



Lincolnshire, East Yorkshire, and Kent in the UK, along with Bremen and Weser-Ems in Germany, plus West-Vlaanderen in Belgium, stood out as prime examples of where such measures might offer noticeable improvements.



<h2 class="wp-block-heading" id="h-north-american-cities-feeling-the-heat">North American cities feeling the heat</h2>



Across the Atlantic, North American coastal hubs like Miami, New York City, and Vancouver are already witnessing visible <a href="https://www.earth.com/news/sea-level-warnings-what-coastal-cities-must-prepare-for/" target="_blank" rel="noreferrer noopener">impacts of rising seas</a>. 



In Miami, neighborhoods flood more often during high tides, disrupting daily life. 



New York City has launched stronger coastal defenses, drawing on lessons from Hurricane Sandy in 2012. 



Vancouver makes sea level rise a central factor in its urban planning, aiming to protect core infrastructure before flooding becomes impossible to manage.



<h2 class="wp-block-heading" id="h-critical-infrastructure-and-preparedness">Critical infrastructure and preparedness</h2>



Bridges, roads, and power systems in <a href="https://www.earth.com/news/sinking-cities-on-u-s-coast-face-a-double-threat-as-sea-levels-rise/" target="_blank" rel="noreferrer noopener">coastal areas</a> are at greater risk, and the resulting damage has a ripple effect on local and national economies. 



People in these communities rely on well-functioning facilities for day-to-day life, so disruptions can bring operations to a halt. 



Elevated roads and bolstered drainage systems offer some protection, but there is a clear need for sustained strategies to avoid overwhelming losses.



<h2 class="wp-block-heading" id="h-mitigating-and-adapting-to-sea-level-rise">Mitigating and adapting to sea level rise</h2>



Engineers and city planners talk about adaptation - physical changes like sea walls or raised foundations that limit damage - as a key approach. 



Mitigation measures, which reduce the underlying <a href="https://www.earth.com/news/un-the-world-is-on-track-for-a-catastrophic-level-of-global-warming/" target="_blank" rel="noreferrer noopener">causes of global warming</a>, also play a part. Lower greenhouse gas emissions may slow the pace of rising waters, making it simpler for local governments to handle gradual changes.



Cooperation among policymakers, businesses, and researchers is essential for managing long-term threats. 



While region-specific tactics vary, the study highlights the importance of policies that address uneven effects on different communities. 



This means that officials in coastal zones, inland areas, and national governments should look for ways to balance resources and safeguard <a href="https://www.earth.com/news/climate-experts-predict-global-warming-will-far-exceed-paris-goals/" target="_blank" rel="noreferrer noopener">at-risk populations</a>.



<h2 class="wp-block-heading" id="h-what-happens-next">What happens next?</h2>



Findings from this research underscore a critical need for policies that respond to <a href="https://www.earth.com/news/climate-models-underestimate-sea-ice-melt-and-global-warming/" target="_blank" rel="noreferrer noopener">climate pressures</a> while taking regional differences into account. 



“The study reveals that inland regions, including areas in Germany, Austria, and Hungary, might experience economic gains of up to 1% of regional GDP by 2100,” the authors report. 



That shift could carry both positive and negative impacts, underscoring the importance of thinking ahead.



<h2 class="wp-block-heading" id="h-global-sea-level-rise-and-the-future">Global sea level rise and the future</h2>



The potential scale of damage offers a stark picture of how climate change affects local economies, international commerce, and everyday life. 



“A key finding of the study is the estimated 872 billion Euros in combined economic losses for the UK and EU alone by 2100,” the research team notes, emphasizing that preparation and innovative planning may help limit setbacks. 



North American coastal cities also grapple with their own risks, investing in forward-looking policies and resilience measures.



In the end, each region’s mix of natural features and economic strengths calls for unique strategies. The comprehensive study, published in Scientific Reports, shines a light on the need to plan thoughtfully as sea levels continue to rise. 



By taking steps to protect homes, industries, and infrastructure, communities can reduce the dangers linked to shifting coastlines.

Study: Coastal cities will spend over $3 trillion on damage from sea level rise

Coastal cities worldwide are confronted with surging waters that threaten...

In September 2022, a catastrophic event unfolded beneath the Baltic Sea. The Nord Stream gas pipelines, which transport natural gas from Russia to Europe, suffered severe ruptures. What followed was an unprecedented emission and release of methane, one of the most potent greenhouse gases.



At the time, experts scrambled to estimate the scale of the damage. Initial assessments suggested a significant but relatively contained leak. However, new research published in the journal Nature has revealed a much graver reality.



The methane emission was over twice the first estimates, making it one of the biggest leaks ever. This discovery has sparked fresh concerns about the environmental impact of fossil fuel infrastructure failures and the urgency of global <a href="https://www.earth.com/news/massive-new-source-of-methane-emissions-discovered-glacial-fracking-arctic/" target="_blank" rel="noreferrer noopener">methane</a> reduction efforts. 



The study, coordinated by the United Nations Environment Programme (<a href="https://www.unep.org" target="_blank" rel="noreferrer noopener">UNEP</a>), offers a more precise understanding of the emissions and the role of advanced satellite technology in detecting such events.



<h2 class="wp-block-heading" id="h-nord-stream-methane-emission">Nord Stream methane emission</h2>



The Nord Stream pipelines ruptured in September 2022, leading to an uncontrolled release of <a href="https://www.earth.com/news/top-10-global-methane-emissions-hotspots-spotted-by-satellites/" target="_blank" rel="noreferrer noopener">methane</a> into the atmosphere. The research shows the leak did more damage than experts first thought.



According to the study, the total volume of methane leaked ranged between 445,000 and 485,000 tonnes. This sharply contrasts with earlier estimates, which suggested a much lower figure of 75,000 to 230,000 tonnes.



Methane traps heat in the atmosphere much faster than carbon dioxide, making it a powerful driver of global warming. Releasing so much of it at once speeds up climate change in ways we can’t ignore.



<h2 class="wp-block-heading" id="h-advanced-satellite-data-collection">Advanced satellite data collection</h2>



To determine the true extent of the <a href="https://www.earth.com/news/rapid-reductions-in-methane-emissions-are-possible/" target="_blank" rel="noreferrer noopener">leak</a>, the researchers used data from multiple sources.



This included several Earth observation satellites such as Copernicus Sentinel-1 and Sentinel-2, along with the Infrared Atmospheric Sounding Interferometer (<a href="https://www.esa.int/Applications/Observing_the_Earth/Meteorological_missions/MetOp/About_IASI" target="_blank" rel="noreferrer noopener">IASI</a>) instrument on Eumetsat’s MetOp-B satellite. Additional data came from ESA’s third-party missions, <a href="https://landsat.gsfc.nasa.gov/satellites/landsat-8/" target="_blank" rel="noreferrer noopener">Landsat 8</a>, and <a href="https://www.ghgsat.com/en/" target="_blank" rel="noreferrer noopener">GHGSat</a>.



The researchers also incorporated marine observations, atmospheric in-situ measurements, aerial monitoring, and engineering calculations. These diverse data sources allowed for a much more accurate analysis of the methane emissions.



Stephen Harris, a scientist at UNEP’s International Methane Emissions Observatory (<a href="https://www.unep.org/topics/energy/methane/international-methane-emissions-observatory" target="_blank" rel="noreferrer noopener">IMEO</a>), emphasized the importance of this approach. 



“Satellite observations were just one component of a broader set of measurement approaches, which together enabled the study to provide a comprehensive and accurate assessment of methane emissions from the event – highlighting the importance of integrating diverse, complementary methane measurement methods,” noted Harris.



<h2 class="wp-block-heading" id="h-tracking-methane-emissions">Tracking methane emissions</h2>



The study involved 70 scientists from 30 research organizations. It was partially funded by two ESA Earth Observation Science for Society initiatives: <a href="https://methanecamp.fmi.fi" target="_blank" rel="noreferrer noopener">MethaneCamp</a> and Methane+.



“This study shows the benefits and importance of methane concentrations provided by satellites on a regular basis,” said Edward Malina, an ESA Earth Observation Atmosphere Scientist.



Diego Fernandez Prieto, Head of ESA’s Earth Observation Science Section, explained the significance of satellite advancements in tracking methane emissions.



“Sustained ESA support to scientific advances on methane measurements from satellites have improved our ability to characterize methane leaks globally. I believe this is a good example of how science is transferred into climate action as we are now better equipped to monitor <a href="https://www.earth.com/news/rising-methane-emissions-threaten-earths-habitability/" target="_blank" rel="noreferrer noopener">progress</a> and respond to the Global Methane Pledge,” said Fernandez Prieto.



<h2 class="wp-block-heading" id="h-extent-of-the-methane-leak">Extent of the methane leak </h2>



The Nord Stream methane leak is now one of the biggest ever recorded. At its highest estimate, it released more than four times the methane from the 2015–2016 Aliso Canyon leak in the United States, which was previously one of the largest known emissions.



However, despite its scale, the Nord Stream event accounted for just 0.1% of all human-caused methane emissions in 2022. 



“This is equivalent to only two days of the oil and gas industry’s annual methane emissions. This highlights the vast number of other human-caused <a href="https://www.earth.com/news/climate-extremes-will-boost-methane-emissions-in-the-amazon/" target="_blank" rel="noreferrer noopener">methane</a> sources that still require global mitigation efforts,” said Harris.



<h2 class="wp-block-heading" id="h-methane-emissions-are-a-global-issue">Methane emissions are a global issue</h2>



The International Energy Agency estimates that the production and use of fossil fuels resulted in nearly 120 million tonnes of methane emissions in 2023.



Another 10 million tonnes came from bioenergy. Methane levels have remained consistently high since peaking in 2019.



The findings of this study reinforce the need for stronger global efforts to track and reduce methane emissions. The <a href="https://www.globalmethanepledge.org" target="_blank" rel="noreferrer noopener">Global Methane Pledge</a>, which aims to cut methane emissions significantly, relies on improved monitoring and scientific advancements to drive climate action.



<h2 class="wp-block-heading" id="h-understanding-the-leak-s-impact">Understanding the leak’s impact</h2>



Before this study, there was significant uncertainty about the actual volume of methane released from the Nord Stream leak. The latest research offers the most accurate assessment to date, using extensive data analysis and satellite-based measurements.



“The initial estimates, including those from UNEP’s IMEO, were based on data from a limited number of studies, many of which relied on incomplete sources available at the time. Furthermore, these estimates varied widely, each capturing only part of the story from a different perspective,” noted Harris.



”This study presents the first updated estimate that incorporates all available data to account for every aspect of the emission event: the methane present in the pipeline before and after the ruptures, the amount dissolved in the Baltic Sea, and the portion ultimately released into the <a href="https://www.earth.com/news/study-reveals-previously-unknown-sources-of-methane-production/" target="_blank" rel="noreferrer noopener">atmosphere</a>."

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air">Invisible threat in urban air</h2>



City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge">Disturbing connections emerge</h2>



Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.



<h2 class="wp-block-heading" id="h-timing-matters">Timing matters</h2>



The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns">Genetic vulnerability patterns</h2>



Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.



<h2 class="wp-block-heading" id="h-public-health-implications">Public health implications</h2>



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.



As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



<h2 class="wp-block-heading" id="h-implications-for-astrobiology">Implications for astrobiology</h2>



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.



<h2 class="wp-block-heading" id="h-the-discovery">The discovery</h2>



Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.



Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.



Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



<h2 class="wp-block-heading" id="h-a-contrasting-climate-response">A contrasting climate response</h2>



Most coastal towns are <a href="https://www.earth.com/news/sinking-land-will-intensify-the-effects-of-rising-sea-levels/" target="_blank" rel="noreferrer noopener">preparing for higher sea levels</a>, but <a href="https://www.earth.com/news/greenland-no-longer-has-to-worry-about-rising-sea-levels/" target="_blank" rel="noreferrer noopener">Greenland presents</a> a different scenario during climate change. The ground there is rising at a remarkable rate. Over the past decade, some areas have lifted about 20 centimeters, which translates to roughly 2 meters per century. This rate significantly exceeds current projections for sea level rise.



<h2 class="wp-block-heading" id="h-geological-rebound-process-through-climate-change">Geological rebound process through climate change</h2>



The mechanism behind this phenomenon is straightforward. As the ice sheet melts, the immense weight is removed from the bedrock, causing the land to rebound upward. This process resembles the way compressed material springs back when pressure is released.



<h2 class="wp-block-heading" id="h-scientific-monitoring-networks">Scientific monitoring networks</h2>



Researchers at the <a href="https://www.dtu.dk/english/" target="_blank" rel="noreferrer noopener">Technical University of Denmark</a> are documenting this uplift using the GNET network, consisting of 61 GPS stations positioned around Greenland's coast. These sensors can detect movement with millimeter precision, providing detailed measurements of the ongoing changes.



The data reveal that current uplift rates exceed the gradual rebound occurring since the last ice age ended approximately 12,000 years ago. This acceleration corresponds directly with increased ice sheet melting rates.



<h2 class="wp-block-heading" id="h-coastal-transformation">Coastal Transformation</h2>



This uplift is actively reshaping Greenland's coastline. New islands and rocky formations, called "skerries," are emerging as previously submerged land surfaces rise above the water level. This represents a notable contrast to global concerns about rising seas.



The study, published in Geophysical Research Letters, demonstrates the varied regional impacts of climate change. While many locations face rising water levels, Greenland's bedrock is literally rising above the surrounding seas.



The full study was recently published in <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL104851" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a>.

<h2 class="wp-block-heading" id="h-ai-agent-training-transforms-the-workplace-fear-factor-into-a-competitive-advantage">AI agent training transforms the workplace 'fear factor' into a competitive advantage</h2>



Organizations that offer comprehensive artificial intelligence training to their workers find remarkable value that extends well beyond basic <a href="https://www.earth.com/news/mind-wandering-might-be-more-productive-than-you-think/" target="_blank" rel="noreferrer noopener">productivity improvements</a>. Emerging research demonstrates that carefully crafted AI training programs <a href="https://www.earth.com/news/ai-does-not-replace-human-creativity-but-enhances-it/" target="_blank" rel="noreferrer noopener">enhance</a> corporate performance, lower operational costs, and dramatically improve employee psychological well-being by turning workplace uncertainty into professional empowerment.



<h2 class="wp-block-heading" id="h-addressing-the-widespread-ai-anxiety-crisis-among-us">Addressing the widespread 'AI anxiety' crisis among us</h2>



A staggering 53% of employees expressed concern that the use of AI tools to automate work tasks could make them appear disposable to their employers, according to <a href="https://www.microsoft.com/" target="_blank" rel="noreferrer noopener">Microsoft</a>'s 2024 workplace survey. Such pervasive worry about being substituted by machines has caused what researchers have termed "AI technostress" – a psychological state that can result in occupational burnout and poorer mental well-being.



Data published in <a href="https://www.nature.com/palcomms/" target="_blank" rel="noreferrer noopener">Humanities and Social Sciences Communications</a> showed that belief in AI learning ability was a moderator in the link between technology adoption and work pressure, and higher confidence significantly lowered negative psychological responses. Workers provided ample training to become competent with AI software have significantly lower stress.



Companies like <a href="https://www.mindstudio.ai/" target="_blank" rel="noreferrer noopener">MindStudio</a> have platforms for building what are known as "AI Agents". In essence, AI Agents are simply tools that employees can build for themselves or their teams quickly and inexpensively. MindStudio will even train entire companies, from the CEO on down, at no cost. By letting MindStudio empower employees, companies avoid hiring more IT staff, buying more software, and implementing solutions to problems that do not exist.



MindStudio even has partners locally for companies, like <a href="http://www.dominnus.com" target="_blank" rel="noreferrer noopener">Dominnus</a> with offices in the Carolinas, California, and Denver, to help build AI Agents and support employees as they become resident AI experts for their organization. The training provided by MindStudio is applicable across other AI Agent building platforms as well.



<h2 class="wp-block-heading" id="h-revolutionary-productivity-through-focused-learning">Revolutionary productivity through focused learning</h2>



Organizations that implement large-scale AI training programs achieve dramatic outcomes. Employees performed tasks significantly better when they utilized AI support compared to when they didn't, according to <a href="https://www.nngroup.com/" target="_blank" rel="noreferrer noopener">Nielsen Norman Group</a> research findings. Their study documented productivity increases of 66% for a variety of professional tasks.



Federal Reserve Bank of St. Louis research finds workers record 33% higher productivity in time working with generative AI tools. The benefit is equivalent to 5.4% of work time savings for AI users – around 2.2 hours per week for full-time workers.



<h2 class="wp-block-heading" id="h-psychological-well-being-benefits-through-ai-competence">Psychological well-being benefits through AI competence</h2>



The emotional transformation when employees are provided with proper technology training is a fundamental transformation from fear to professional confidence. A survey of 600 employees across industries, carried out by ScienceDirect, proved that AI capabilities strengthen work environment commitment and improve job satisfaction.



A <a href="https://www.lut.fi/en" target="_blank" rel="noreferrer noopener">LUT University</a> study discovered that AI adoption has no direct effect on workers' well-being but does so indirectly through working conditions like task optimization and safety protocols. Strategically deployed AI that involves correct training can actually increase workplace mental well-being.



<h2 class="wp-block-heading" id="h-from-replacement-anxiety-to-partnership-confidence">From 'replacement anxiety' to 'partnership confidence'</h2>



Although 35% of those interviewed in recent McKinsey studies were concerned about workforce displacement, firms with large-scale training initiatives witness such fears dissipate quickly. The World Economic Forum found that two out of three respondents believe AI competencies will enhance their career prospects and job marketability.



This shift from fear to trust has measurable implications for job satisfaction. Applied Sciences research indicates AI can create tailored wellness programs based on individual employee requirements.



<h2 class="wp-block-heading" id="h-financial-benefits-of-increased-retention">Financial benefits of increased retention</h2>



The mental health advantages of AI learning have a direct impact on organizational bottom lines in the form of a positive feedback cycle with high retention of employees. Recent ROI research validates that artificial intelligence learning has a beneficial impact on employee turnover and satisfaction levels.



PriceWaterhouseCoopers' research documents 20% to 30% improvements in productivity, market speed, and revenue in organizations that attempt systematic AI adoption through comprehensive training.



<h2 class="wp-block-heading" id="h-environmental-advantages-of-ai-enabled-teams">Environmental advantages of AI-enabled teams</h2>



AI training has unforeseen environmental benefits as it makes the work environment more efficient. According to a study in Scientific Reports, the carbon footprint in writing and illustrating work is significantly lower when AI performs it compared to humans. AI software produces 130 to 1,500 times less CO2 equivalent per page of text created than human authors.



In addition, AI-driven remote work functionality significantly reduces environmental impact. Research by Cornell University and Microsoft indicates that remote workers reduce greenhouse gas emissions by up to 54% by not commuting daily to offices. Hybrid workers working remotely two to four days a week can reduce their carbon footprint by 11% to 29%.



<h2 class="wp-block-heading" id="h-cumulative-organizational-advantages">Cumulative organizational advantages</h2>



The compounding gains of better mental well-being, reduced turnover, increased productivity, and environmental benefits flow to enterprises from the pairing. McKinsey analysis estimates the long-term AI potential at $4.4 trillion in incremental productivity growth opportunity from business use cases.



As of now, 75% of knowledge workers globally utilize generative AI, mirroring widespread adoption patterns. Organizations that provide organized training and assistance see the most favorable results in productivity, worker satisfaction, and ecological sustainability.



The research overwhelmingly indicates that companies that invest in proper AI education, like that offered through <a href="https://www.mindstudio.ai" target="_blank" rel="noreferrer noopener">MindStudio</a>, establish win-win scenarios where employees are both more empowered and less stressed, and companies enjoy the gains of increased productivity, reduced turnover, and improved mental health outcomes throughout their workforce.

<h2 class="wp-block-heading" id="h-a-natural-solution-to-disease-through-crop-modification">A natural solution to disease through crop modification.</h2>



The agricultural industry stands at a crossroads between productivity and environmental responsibility, and crop modification often carries a negative connotation. While chemical pesticides have long been the go-to solution for crop protection, their harmful effects on ecosystems and human health have prompted scientists to seek alternatives. The recent breakthrough by <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> researchers offers a promising path forward through the precise manipulation of plant-associated microbial communities.



<h2 class="wp-block-heading" id="h-the-science-behind-microbial-partnerships">The science behind microbial partnerships</h2>



Plants naturally harbor diverse ecosystems of bacteria, fungi, and other microorganisms that function as biological allies. These microscopic partners contribute to disease resistance, nutrient absorption, and stress tolerance. However, until now, scientists lacked the tools to deliberately reshape these communities to enhance crop protection.



The Southampton team's approach centered on <a href="https://www.earth.com/news/engineered-plant-microbiomes-the-future-of-crop-protection/" target="_blank" rel="noreferrer noopener">modifying lignin biosynthesis genes in rice plants</a>. This strategic intervention altered the plant's metabolic output, creating conditions that favored beneficial bacterial populations while suppressing harmful ones. The result was a living defense system embedded within the plant itself.



<h2 class="wp-block-heading" id="h-implications-for-global-food-security">Implications for global food security</h2>



The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.



<h2 class="wp-block-heading" id="h-the-path-forward">The path forward</h2>



As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.

<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Wildlife tunnels save millions of amphibians

https://youtu.be/XYgiPzmNBTU?si=eFYY7gPHU1JznLvU A new long-term study in Monkton, Vermont, reveals that...

Scientists are transforming chocolate into a functional food by infusing it with probiotics and prebiotics, aiming to create a treat that satisfies cravings while supporting gut health. 



The challenge lies in maintaining chocolate's beloved texture and flavor while adding health benefits.



<figure class="wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio"><div class="wp-block-embed__wrapper">

</div></figure>



Probiotics - beneficial microbes that balance gut bacteria and aid digestion - are typically fragile and can be destroyed by stomach acid or processing. 



Prebiotics act as food for these microbes, helping them thrive. Together, they form "synbiotics," a powerful health combination.



Researchers Smriti Gaur and Shubhi Singh from India's Jaypee Institute of Information Technology took an innovative approach, using natural prebiotics like corn and honey instead of complex processing methods. 



They created five chocolate varieties: a control and four synbiotic versions containing different combinations of prebiotics, probiotics (Lactobacillus strains), and flavor enhancers (cinnamon or orange).



Laboratory simulations of human digestion showed the probiotics remained viable for over five hours, suggesting they could survive long enough to benefit gut health.



Taste tests were positive, with researchers particularly enjoying the orange-flavored variety, describing it as having "vibrant citrus notes" complementing the "rich cocoa" with a "luxurious" texture.



This research represents just the beginning. With further refinement of strains, textures, and flavors, chocolate could evolve beyond mere indulgence to become a functional food that nourishes while it delights.



The study is published in the journal <a href="https://pubs.acs.org/doi/10.1021/acsfoodscitech.4c00741" target="_blank" rel="noreferrer noopener">ACS Food Science &amp; Technology</a>.

Today’s Video of the Day from <a href="https://www.igb.illinois.edu/">Carl R. Woese Institute for Genomic Biology</a> reveals how scientists can modify common crops like soybean, rice, and wheat to protect them from heat stress.



“We need to double crop production by 2050 to feed a growing global population, and not only are we not on track to do that, but climate change is further complicating things,” said Amanda Cavanagh, a lecturer at the University of Essex. 



The study is part of Realizing Increased Photosynthetic Efficiency (RIPE), an international research project that aims to develop food crops that turn the sun’s energy into food more efficiently.



“Using an engineering approach we designed multiple alternative metabolic pathways to photorespiration. Testing them in the field showed increases in productivity which led Amanda to significantly move the project forward by showing our engineered plants can withstand pretty extreme temperature stress,” said study co-author and RIPE researcher Paul South.&nbsp;



“As the climate changes and temperature stresses increase the pressure on our global food supply, farmers will need every tool available including engineering approaches like the synthetic biology used here to maintain safe and productive harvests.”



The experts tested plants modified to have more efficient photorespiration to see if they were better adapted to warmer temperatures.&nbsp;



The team found that the engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures, and had 15 percent less yield loss under the higher temperatures.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes the first comprehensive estimate of carbon density in the Saharan, Sahel, and Sudanian zones of Africa. In an effort to measure the amount of carbon stored across these drylands, a team of scientists used high-resolution satellite images and artificial intelligence to map nearly 10 billion individual trees. 



"The high spatial resolution (50 cm) combined with AI and field measurements used in this study is key to improving tree inventories in drylands," said Pierre Hiernaux, a French researcher working for NASA. "The ever-increasing availability of very high-resolution satellite imagery will make it possible to assess carbon pools and their dynamics at the individual tree level on a global scale."



"This study is exceptional because it is pioneering a type of approach that will revolutionize the monitoring of trees and forests on a global scale: in the short term, it will be possible to map the world's trees from the centre of the Amazon to our schoolyards," said <a href="https://www.inrae.fr/en">INRAE</a> researcher Jean-Pierre Wigneron.



"Many fields of application will become much more efficient and accurate, such as tracking carbon stocks, biodiversity, monitoring logging and protection against illegal forest degradation, in near real time.”

Lesotho: Africa's "Kingdom in the Sky" Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features northwest Lesotho in South Africa.



According to ESA, Lesotho is the only nation in the world that lies completely above 1,000 m in elevation. The country is famous for its tall mountains and narrow valleys, and is known as Africa's "Kingdom in the Sky."



Out of a population of around two million people, about 80 percent live in rural areas. More than 75 percent of these people are engaged in <a href="https://www.earth.com/news/climate-change-will-have-a-global-impact-on-agriculture/">agriculture</a>, including rainfed cereal production and animal grazing.&nbsp;



ESA reports that the country’s agricultural system faces a growing number of issues, with climate-related vulnerabilities such as drought, floods and extreme temperatures occurring more frequently. 



Diamonds are amongst the minerals found in the mountains. Indeed, Lesotho can truly be called the Kingdom in the Sky. Beautiful, culturally rich, safe, affordable, and easily accessible from Durban and Johannesburg, mountainous Lesotho is a vastly underrated travel destination. the Kingdom of Lesotho (Sotho: 'Muso oa Lesotho) is an enclaved country in southern Africa. It is just over 30,000 km2 (11,583 sq mi) in size and has a population of around 2 million.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> features a visual dataset of.methane emissions from wetlands across the globe. Atmospheric methane levels have reached record highs in recent years, and wetlands are a major source of these emissions.&nbsp;



"Methane is an important greenhouse gas that contributes substantially to global warming. On a molecule by molecule basis, methane is much more efficient at trapping heat than carbon dioxide, the main driver of warming," says NASA.



"Though human activities, including agriculture, oil and natural gas production and use, and waste disposal, collectively contribute the majority of methane to the atmosphere, about a third of total methane emissions comes from wetlands."&nbsp;



According to NASA, understanding methane emissions from wetlands and other natural sources is critically important for scientists and policymakers who are working to combat climate change by reducing emissions from human activities.

Today’s Video of the Day from <a href="https://earthobservatory.nasa.gov/">NASA Earth Observatory</a> reveals the evolution of the Columbia Glacier in southeastern Alaska. Columbia is among the fastest shrinking glaciers in the world, and the video documents its rapid retreat over the years.&nbsp;



Columbia Glacier is a large, multi-branched calving glacier that flows out of the Chugach Mountains to the Prince William Sound.&nbsp;



According to USGS, Columbia had a long history of stability prior to 1980, with a length 41 miles, and small, short-lived advances or retreats.



In the years since 1980, however, satellite images have captured Columbia’s alarming retreat. By using false-color images, scientists can distinguish between snow and ice, open water, vegetation, and rocky debris on the glacier’s surface.



The series of false-color images featured in today's video were acquired over the span of 35 years. You can see that by 2021, the glacier’s main branch had retreated about 15 miles from its initial position.



The Columbia Glacier has also lost more than 50 percent of its volume, mostly due to calving. <a href="https://www.earth.com/video/nasa-reveals-3d-visual-of-an-atmospheric-river/">NASA</a> reports that while climate change likely started the retreat, mechanical processes kept the disintegration going.



The NASA images are provided by Jesse Allen, Robert Simmon, Joshua Stevens, and Lauren Dauphin using data from Landsat satellites, from the U.S. Geological Survey, and data from MODIS on NASA’s Terra satellite. The structure of Columbia’s moraine played a large role in the stability of the glacier before 1980. 



Like other tidewater glaciers, the Columbia built up a moraine over time, and the mixture of ice and rock functioned like a dam keeping out the sea. It was supported on one end by the shoreline and by the underwater terminal moraine at the other.

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."
