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.

California continues to lead the way in the battle against climate change with expanded climate legislation backed by Governor Jerry Brown. Legislative negotiations on a plan to extend <a href="https://www.earth.com/news/california-become-wetter-century/">California's</a> climate initiative has been expanded beyond air quality and climate change to include the state’s shortage of affordable housing.

A bill to extend the initiative for another decade is scheduled to go before state legislative committees today. A possible vote in the California Assembly and Senate, which had been scheduled for Thursday night, has been pushed back to Monday, <a href="http://hosted.ap.org/dynamic/stories/U/US_CALIFORNIA_CLIMATE_CHANGE?SITE=AP&amp;SECTION=HOME&amp;TEMPLATE=DEFAULT&amp;CTIME=2017-07-12-00-45-51">AP</a> reported.

Progressive Democrats in the California Assembly said they would not approve an extension to the state’s landmark cap and trade program to fight climate change, without also addressing housing problems, the <a href="http://www.latimes.com/politics/la-pol-sac-cap-trade-housing-20170713-story.html">Los Angeles Times</a> reported.

“Housing is the biggest problem facing the state of California,” said Assemblyman Todd Gloria (D-San Diego), the Times reported. “While climate change, of course, is an existential threat, we can do both. We need to do both”. 

High-profile housing bills introduced this year include a new $75 fee on real estate transactions to raise roughly $250 million a year in low-income housing subsidies and a $3 billion low-income housing bond to be put before voters in 2018, the Times said.

Funding bills require two-thirds votes to pass. While Democrats hold supermajorities in both houses of the legislature, some Democrats are losing interest in the housing bills after raising fuel taxes in April, the Times said.

<a href="https://www.earth.com/news/effective-steps-battle-climate-change/">Climate change</a> is a current and gradually increasing problem for our planet, which is likely not news to you. But some of the consequences of climate change may catch you by surprise. When the air gets warmer, its density decreases. Air with less density (also known as “thin” air) makes it harder for airplanes to generate lift from their wings. Because of this, rising global temperatures due to climate change may actually make it harder for airplanes to take off in the not-to-distant future.

A new study in the journal <a href="https://link.springer.com/journal/10584">Climate Change</a> presents a global analysis that looked at how rising temperatures affect airplanes and airports. Researchers estimate that if our current emissions continue at this rate, fuel capacities and payload weights on airplanes may have to be reduced by as much as 4 percent on particularly hot days. For the average aircraft (roughly 160 seats), a 4 percent weight reduction is equal to about 12 to 13 passengers. Such temperature-related issues could cause major delays and travel headaches for airports and passengers in many countries.

Airplanes with lower temperature tolerances will also be at a greater risk for these problems, and airports located in hotter parts of the world with shorter runways or at high elevations will also see these issues exacerbated. For example, researches estimate that on LaGuardia’s short runways, a Boeing 737-800 may have to offload weight half of the time during New York’s hottest days.

“As the world gets more connected and aviation grows, there may be substantial potential for cascading effects, economic and otherwise,” says study coauthor Radley Horton, a climatologist at Columbia University.

Average global temperatures have risen nearly 1 degree Centigrade since 1980, and may already be having an effect on certain areas of the planet. Just this past June, American Airlines canceled more than 40 flights out of Phoenix when temperatures hit highs of almost 120 degrees. These high temperatures made it dangerous for smaller regional jets to take off.

Besides simple safety issues, this also negatively impacts the airline industry, which generally operates on a razor-thin margin to begin with. Modifications to airplane engines and body designs could help mitigate the heat problem, but they would come at great cost. This study just shows another example of how climate change has consequences that reach far across the planet and touch almost every part of our lives.

Stress raises the chances that pregnant women exposed to toxic chemicals will have a low birth weight baby, a new study found.

"It appears that stress may amplify the health effects of toxic chemical exposure, which means that for some people, toxic chemicals become more toxic," said Tracey Woodruff, a <a href="http://berkeley.edu/">University of California - Berkeley</a> professor and lead author of the study.

This is the first study to examine the combined effects of <a href="https://www.earth.com/news/marijuana-low-doses-relieve-stress/">stress</a> and environmental toxic chemical exposures on fetal growth, researchers said.

High-stress pregnant women who smoked were about twice as likely to have a low birth weight baby as low-stress smokers, the study found. Stress was quantified by factors such as socioeconomic status or years of paternal education. 

The effects of air pollution on low birth weight were heightened when combined with stress, the researchers found. Exposure to ambient fine particulate matter, a type of air pollution, increased the risk of African-American women having a low birth weight baby compared to those who were white.

The study, published in the journal <a href="http://journals.plos.org/plosone/">PLOS ONE</a>, was based on a systematic review of 17 human studies and 22 animal studies examining the links between chemicals, stress and fetal development.

"While the evidence on the combined effects of chemicals and stress is new and emerging, it is clearly suggestive of an important question of social justice," said co-author Rachel Morello-Frosch at UC Berkeley.

Poverty-related stress may make people more susceptible to the negative effects of environmental hazards, she said. 

"That needs to be a consideration for policymakers and regulators," Morello-Frosch said.

A massive iceberg weighing over 1 trillion tons has broken off the Larsen C ice shelf in Antarctica, scientists announced Wednesday morning.

The iceberg, which most likely will be named A68, has been described as twice the size of Lake Erie and measures 2,240 square miles in size.

The event was anticipated by researchers from Project MIDAS and <a href="http://www.swansea.ac.uk/">Swansea University,</a> who had been monitoring Antarctica ever since the Larsen A ice shelf collapsed in 1995 and the Larsen B shelf dissolved in 2002.

"We have been anticipating this event for months, and have been surprised how long it took for the rift to break through the final few kilometers of ice," said Adrian Luckman, researcher from <a href="http://www.swansea.ac.uk/">Swansea University</a>. "We will continue to monitor both the impact of this calving event on the Larsen C Ice Shelf, and the fate of this huge iceberg."

The event has completely reshaped the <a href="https://www.earth.com/video/massive-iceberg-larsen-c-ice-shelf/">Larsen C</a> ice shelf, reducing it by 12%, which will require maps to be redrawn.

While the team noted that this was a natural event not caused by human-induced climate change, it still leaves the ice shelf in danger of further dissipation. 

From here, the iceberg is likely to break into smaller chunks, with some pieces remaining in the water for decades, while others will make their way into warm waters and melt.

The new iceberg is about half the size of the largest iceberg ever recorded. B15 broke off Antarctica’s Ross ice shelf in 2000 and measured a whopping 4,250 square miles.

Nearly 90 percent of American households use <a href="https://www.earth.com/news/summer-air-conditioning-pollution/">air conditioning</a> during the hot summer months. That’s understandable, but the planet pays a price. All of those air conditioners release 100 million tons of carbon dioxide into the atmosphere -- and that, of course, contributes to climate change. It can also overload the power grid when everyone is blasting their ACs full power. 

You’re not going to toss your air conditioner (and anyway, that burdens landfills and can leak hydrofluorocarbons). But there are ways you can reduce your reliance on window units or central air and save money -- without significantly increasing your discomfort. Here are a few tips.

Dress for the weather. Sure, you spend your downtime in shorts and flip flops. But how do you dress for work? Is your company old school when it comes to dress code? If the requirements are dress casual or even more formal, you might not be dressed for the weather. Tell your boss that the business could save on energy costs with a more relaxed summer dress code. If you’re the boss, comfortable attire could increase morale and boost productivity while cutting costs. Win win.

Don’t chill out. We’ve all seen (or been) restaurant diners bringing sweaters into the establishment during an August heat wave. Many homes and commercial spaces air condition well beyond the comfort needs of visitors and occupants. Try dropping your home or business thermostat setting a notch or two. Back off if you feel uncomfortable or others complain, but you just might save money and increase comfort with this easy step.

Use the heat cycle. It’s rarely uniformly warm on even the hottest summer days. It’s generally cooler early in the day and after the sun goes down. Can you use that time better? Dial up the AC and step out to do your gardening, walk the dog, cut the grass or run errands during these relatively cool dayparts.   

Hug a tree. Or at least get on a first name basis with a few. Trees strategically placed around your property can keep the radiant sun out of your house and cool your yard. Take a few ticks off of your AC setting at home and bring the kids to the park. Or sit in the shade with a book or a laptop to get some work done. Trees rock during the sweltering summer months.

‘Summerize’ your home. Make sure you have screens in place, then open windows and use or install ceiling fans to stir up whatever breezes can be found. Also, it might sound counterintuitive, but better insulating your home blocks the summer heat as well as it keeps the icy air out in the winter. Add plantings or window shades outside to reduce the sun’s impact.  All of these steps can help reduce the time you need your air conditioner or at least allow you to use it more efficiently. 

Stay temp aware. Is the AC running 24/7 simply because it’s summer and probably hot out? Find out if that’s true. Step outside or get a current temp reading on your phone. If you can adjust the AC setting or even turn it off altogether and open the windows you’ll save money while doing the planet a solid.

Rising temperatures that result from global warming may lead to major losses for the European wine industry. New research is shedding light on the potential impact of warmer weather in <a href="https://www.earth.com/image/the-western-mediterranean-sea/">Mediterranean</a> countries. The study reveals that labor and productivity could suffer as agricultural workers try to adjust to the heat.

Unlike most other major industries, the production of wine is still largely operated by manual workers. Because of this, experts believe the wine industry is likely to take a direct hit from the effects of global warming. The researchers set out to examine the influence of heat on the productivity and labor output of manual grape-picking workers in Cyprus to test this theory. These laborers work in temperatures that reach over 96 degrees Fahrenheit. 

The researchers used an innovative technique known as time-motion analysis to evaluate labor output and productivity of seven workers. Time-motion analysis is a reliable method of discovery, as it can account for every second spent by each worker during every shift.

The study established that hot summer temperatures coincided with labor loss up to 27 percent. The workers felt they were exerting more energy due to the impact of the heat on their metabolic and cardiovascular systems and labor output suffered as well. The hotter temperatures caused a need for irregular breaks, and the workers engaged in working activities for 15 percent less time. 

The findings of this study, published in the journal <a href="http://www.tandfonline.com/loi/ktmp20">Temperature</a>, suggest that workplace heat is directly related to labor and productivity losses, particularly in European agricultural workers. The wine industry makes up 0.2% of all the goods and services produced worldwide, which means increased temperatures are a potential source of economic losses on a global scale.

The study is an unprecedented assessment of the impact of workplace heat on European agriculture workers. However, the authors express a need for expansion of this study to accurately predict the scope of global warming’s influence on agricultural laborers in the wine industry. Further research is needed that will include wine production workers in other countries.

Billions of gallons of <a href="https://www.earth.com/news/oklahoma-earthquake-wastewater-injection/">wastewater</a> result from hydraulic fracturing. While this technique has produced a wealth of energy resources for the United States, researchers are taking a look at the environmental impact of this unconventional process. According to a new report, the release of wastewater in Pennsylvania has contaminated a watershed with radioactive material and endocrine-disrupting chemicals.

Hydraulic fracturing, or “fracking,” is a method of extracting gas and oil. According to the U.S. Energy Information Administration, this practice accounted for over half of oil production and two-thirds of gas production in the United States in 2015, and these numbers are expected to grow. Hydraulic fracturing has led to a major shift away from relying on coal, which could significantly reduce greenhouse gas emissions. However, environmental risks also come along with the process such as ground and surface water contamination. 

Fracking produces large amounts of wastewater containing radioactive material, salts, metals, endocrine-disrupting chemicals and polycyclic aromatic hydrocarbons that pose environmental and health risks. A recent report in Pennsylvania estimates that 10,000 oil and gas wells in the Marcellus Shale produced 1.7 billion gallons of wastewater in 2015. The water is collected in facilities to be treated before it is released, but the treatment is limited. 

Bill Burgos led a team of experts from Penn State, Colorado State, and Dartmouth in an effort to determine how effective these water facilities are in treating the wastewater from hydraulic fracturing. They sampled water and sediment from a lake located downstream from two of the treatment facilities. The analysis revealed peak concentrations of radium, alkaline earth metals, salts and organic chemicals present in the same sediment layer.

Two classes of organic chemicals were detected including endocrine-disrupting chemicals known as nonylphenol ethoxylates and carcinogens known as polycyclic aromatic hydrocarbons. The highest concentrations were detected in sediment layers deposited 5 to 10 years ago, which was a peak period of wastewater disposal. High levels of radium were also present in water as far as 12 miles downstream from the treatment plants.

The researchers say that the threats to human health and the environment associated with this contamination are unknown. They express a need for modified regulations of wastewater disposal. The study is published by the <a href="https://www.acs.org/">American Chemical Society</a> in the journal <a href="http://pubs.acs.org/journal/esthag">Environmental Science &amp; Technology</a>.

Seaside sparrows usually live in tidal marshes and build their nests just above normal high tide where they can stay hidden from predators in the vegetation. Rising sea levels may put these birds in a predicament, as unusually high tides will destroy their nests. However, moving their nests up makes them more vulnerable to predators. A new study  from <a href="http://www.americanornithologypubs.org/loi/cond">The Condor: Ornithological Applications</a> reveals that despite the increasing risk of flooding, the nests of these saltmarsh birds face much more of a threat from predation.

Elizabeth Hunter of the <a href="http://www.uga.edu">University of Georgia</a> developed a model to simulate the nesting behavior and success rates of seaside sparrows on the coast of Georgia. Her model revealed that predation poses a much greater threat to the survival of seaside sparrows.  

The study established that flooding risk did not influence predation rates, but predation risk did impact flooding risk - due to the fact the sparrows move their nests lower for safety. Despite this increased risk of flooding paired with a projected spike in sea levels, predation risk remains almost seven times more menacing to seaside sparrows than flooding.

"Nest predation rates are so high right now that even under extreme sea level rise conditions, more nests are likely to be eaten than flooded," explained Hunter. "However, predation and flooding threats act synergistically, meaning that any estimates of the negative effects of sea level rise on the nesting success of Seaside Sparrow or other species are likely underestimates if they do not also consider the negative effects of predation on flooding risk. The flip side of this is that management actions to reduce nest predation could also reduce the risk of nest failures from flooding." 

If conservation strategies are used to protect seaside sparrows from predators, they can overcome the threats of both flooding and predation. The birds could place their nests higher up to stay clear of extreme high tides if their nesting sites were fenced in, for example.

Chris Elphick of the <a href="http://uconn.edu">University of Connecticut</a> is an expert on tidal <a href="https://www.earth.com/news/saltmarsh-sparrow-may-go-exctinct/">marsh birds</a> who commented on Hunter’s study. 

"The study nicely illustrates the importance of understanding the behavior of individual birds when trying to devise strategies to mitigate threats such as predation and tidal flooding,” said Elphick. “Regardless of the threat, it is increasingly clear that tidal marsh birds and their habitats are in trouble, and that we need to explore a range of potential solutions to find ways to help them persist in light of the many ways that humans are changing coastal habitats."

In teaching people about how to reduce their carbon footprints, governments and schools aren’t highlighting the most effective steps, according to a new study.

The four steps that most substantially decrease carbon footprint are eating a plant-based diet, avoiding air travel, living car-free, and having smaller families, the <a href="http://www.lunduniversity.lu.se/">Lund University</a> study said.

However, many governments are still promoting strategies like comprehensive <a href="https://www.earth.com/news/plastic-bottle-threatens-environment/">recycling</a>, which is four times less effective than a plant-based diet, or changing household light bulbs, the study said.

The research analyzed 39 peer-reviewed papers, carbon calculators, and government reports to develop the potential of a range of individual lifestyle choices to reduce greenhouse gas emissions.

The researchers found that government resources from the EU, United States, Canada and Australia don’t highlight these actions, instead focussing on incremental changes with much smaller potential to reduce emissions.

"We recognize these are deeply personal choices,but we can't ignore the climate effect our lifestyle actually has,” study co-author Kimberly Nicholas said. “Personally, I've found it really positive to make many of these changes. It's especially important for young people establishing lifelong patterns to be aware which choices have the biggest impact.”

The most effective individual steps to battle climate change

In teaching people about how to reduce their carbon footprints,...

Warmer Arctic temperatures have triggered cooler winters and springs in North America, which has weakened vegetation growth and lowered carbon uptake capacity in its ecosystems, according to a new study. 

Researchers analyzed an index of sea surface temperatures from the Bering Sea and found that in years with higher-than-average <a href="https://www.earth.com/news/delay-antarctic-ozone-recovery/">Arctic</a> temperatures, changes in atmospheric circulation affected climate throughout North America. 

In years of intense cold and low precipitation, the team found that the unfavorable conditions adversely affected vegetation growth—including crop yields—which decreased carbon uptake capacity by about 14 percent, the study said.

“If current warming trends continue, it is feasible to conclude that the ecosystems in regions affected by the anomalous climate will suffer greater damages due to the cold and dry spells,” the authors saId.

Further research is needed to obtain a “general conclusion” on the matter, but the research “delivers important implications for climate adaptation,” the authors added.

The study was conducted by Jin-Soo Kim and Jong-Seong Kug at <a href="http://www.postech.ac.kr/">Pohang University of Science and Technology</a> (POSTECH), in collaboration with Su-Jong Jeong from <a href="http://www.sustc.edu.cn/en/">South University of Science and Technology </a>in China. It  is published in the journal <a href="http://www.nature.com/ngeo/"> Nature Geoscience.</a>

Home batteries used to store power from solar panels in individual houses could become commercially competitive in the 2030s, a new study found.

The findings from <a href="https://www.imperial.ac.uk/">Imperial College London</a> are based on a new analysis tool that predicts how much consumers will have to pay in the future for energy storage technologies.

"Energy storage has been recognized by leading figures such as Barack Obama and Bill Gates as one of the key technologies of a low-carbon 21st century,” said lead author Oliver Schmidt. “With this analysis tool we can quantify when energy storage becomes competitive and identify where to invest to make it happen, thereby minimizing investor and policy uncertainty."

Renewable energy sources like solar or wind only produce power intermittently and if excess amounts are not stored, they are wasted, the researchers said. Currently, most energy storage technologies are still very new and have a high cost, the study said.

As more units are produced, costs usually fall, researchers said, citing renewable power generators, such as <a href="https://www.earth.com/news/tesla-solar-roof-tiles/">solar panels</a>.

With reasonable investment, energy storage technologies could soon become much cheaper, with electric cars leading the way as battery technology costs fall, the new study says.

The Hinkley Point C nuclear power plant in Great Britain is projected to cost £19.6bn, and produce 3.2 gigawatt (GW) of power on demand when it is completed in 2025, the study said.

If the same amount of money were invested in large-scale lithium-ion batteries, they would be able to deliver 21-41 GW of power when charged, the analysis said. That is more than ten times the UK's current electricity storage capacity, enabling the use of significantly more wind and solar energy.

"This tool allows us to combat one of the biggest uncertainties in the future energy system, and use real data to answer questions such as how electricity storage could revolutionize the electricity generation sector, or when high-capacity home storage batteries linked to personal solar panels might become cost-effective," said study co-author Iain Staffell.

Most air and water pollution in Europe is from coal-powered plants, with Great Britain among the worst polluters, the European Union said.

Half of the plants responsible for the largest releases of air and water pollution were in Britain, with a total of 14, <a href="https://www.eea.europa.eu/">The European Environment Agency</a> reported. Second was Germany with 7, followed by France and Poland, each with 5.

The report was based on 2015 data, the latest available, from 35,000 industrial plants including power stations, petrochemical refineries and metal processing units from the 28 EU members plus Iceland, Liechtenstein, Norway, Switzerland and Serbia.

The report noted progress by the EU in reaching its climate and energy policy objectives for 2020 and 2030, but said <a href="https://www.earth.com/news/obama-protect-streams-forests-coal-mining/">coal</a> is still the most highly used fuel in large combustion plants despite a tripling in the use of biomass from 2004 to 2015.

Coal is still responsible for the largest releases of carbon dioxide, sulfur dioxide and nitrogen oxides, although some plants have significantly decreased their emissions in recent years, the report said.

Plants with the highest emissions in 2015 were the Belchatow power plant in Poland, the Drax power station in Britain, Jaenschwalde in Germany, and Kozienice in Poland, the agency said.

<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.

<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.

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."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.
