Wildfires in the western U.S. have become a growing crisis. They’re lasting longer, burning hotter, and spreading into areas that rarely burned in the past. 



But another danger is rising, beyond heatwaves and droughts. Lightning - sudden, fierce, and incredibly powerful - is becoming one of the biggest wildfire risks.



In the coming decades, scientists warn that lightning will become an increasingly dominant spark for <a href="https://www.earth.com/news/climate-change-is-making-wildfire-smoke-more-deadly/">wildfires</a>, adding to the already mounting risks across the West.



<h2 class="wp-block-heading" id="h-lightning-is-fueling-more-wildfires">Lightning is fueling more wildfires</h2>



Wildfires need a few things to get going: dry fuel, hot temperatures, low humidity, and a spark. <a href="https://www.earth.com/news/lightning-is-changing-the-atmosphere-in-surprising-ways/">Lightning</a> is one of the most powerful natural igniters.



In the western U.S., lightning already causes more than two-thirds of the area burned by wildfires. And now, new research shows that number is going to rise sharply due to climate change. 



Warmer air holds more moisture, which means more unstable weather patterns. Those patterns, in turn, set the stage for more lightning.



A recent study has revealed that virtually all of the western U.S. - 98 percent of the region - will have more days with a greater likelihood of lightning-ignited wildfires starting as early as the 2030s. 



For regions already accustomed to such fires, such as Oregon, Idaho, and Montana, the risk is even greater. As early as 2060, those states may have as many as 12 additional lightning-filled days per summer.



<h2 class="wp-block-heading" id="h-a-model-to-forecast-lightning">A model to forecast lightning</h2>



Traditional <a href="https://www.earth.com/news/climate-models-underestimate-sea-ice-melt-and-global-warming/">climate models</a> don’t really track lightning. That’s why a team of researchers led by Dmitri Kalashnikov built their own system to fill in the gaps.



“The first step was to project lightning,” said Kalashnikov, a research scientist at the <a href="https://www.ucmerced.edu/" target="_blank" rel="noreferrer noopener">University of California Merced</a>. “The typical climate models don’t directly simulate lightning. It’s too small a process.”



The researchers applied machine learning to forecast where lightning would hit based on variables that we can quantify - such as temperature, humidity, and the level of <a href="https://www.earth.com/news/moisture-in-the-atmosphere-causes-extreme-weather-to-last-longer/">moisture in the air</a>. 



The team merged those results with the Fire Weather Index (FWI), a mechanism that was developed back in 1968 to monitor how probable wildfire initiation and spread is from local weather.



The result is a forecast model tailored to the western U.S., designed to project conditions from 2030 to 2060 - decades earlier than most studies, which typically look only to the end of the century.



<h2 class="wp-block-heading" id="h-more-lightning-in-the-northwest">More lightning in the Northwest</h2>



The northwestern states of Idaho, Oregon, and Montana are projected to experience the greatest growth in lightning days. But strangely, they may not experience the most rapid expansion in wildfires. 



Although lightning will grow, the conditions favoring fires (such as extreme heat or dryness) are not expected to worsen as quickly in the Northwest compared to other regions.



That doesn’t mean northwestern states are off the hook. Cloud-to-ground lightning, the kind that hits trees or grass directly, is still expected to rise significantly in those areas.



<h2 class="wp-block-heading" id="h-less-lightning-greater-wildfire-risk">Less lightning, greater wildfire risk</h2>



In contrast, the Southwest - including Colorado, Wyoming, Arizona, and New Mexico - won’t see as much of a jump in lightning strikes. But the fire risk will still climb. 



This is because even a small spark becomes a big threat when the land is extra dry, the heat is intense, and there’s little rain to cool things off.



The researchers found that these southern states are likely to experience the biggest increases in wildfires caused by lightning, despite the smaller bump in lightning activity. That’s because climate change is pushing up the number of fire-prone days overall.



<h2 class="wp-block-heading" id="h-dry-and-wet-lightning">Dry and wet lightning</h2>



Kalashnikov said the next steps could involve separating the kinds of lightning events. “You can’t help but wonder what the future will look like, especially if you dig in and you realize that there’s actually a lot that we don’t understand,” he said.



One key factor will be figuring out how to distinguish between "dry lightning" and "wet lightning." Dry lightning happens without much rain, making it a fire hazard. 



Wet lightning brings <a href="https://www.earth.com/news/heavy-rainfall-poses-extreme-risks-in-the-western-us/">heavy rain</a>, which can reduce fire risk but increase flood danger. Understanding that difference could help emergency services respond more precisely to fire threats.



<h2 class="wp-block-heading" id="h-wildfire-risks-are-rising-fast">Wildfire risks are rising fast</h2>



As climate patterns shift, the West isn’t just getting warmer and drier - it’s getting stormier in a dangerous way. Lightning is expected to spark more fires, and fires are expected to find more dry fuel waiting. It’s a feedback loop that could reshape fire seasons in the U.S.



This isn’t about something that might happen a hundred years from now. The changes are coming within the next few decades - some may already be happening. 



And for the people living in <a href="https://www.earth.com/news/double-hazard-wildfire-zones-identified-in-the-american-west/">high-risk areas</a>, that means more heat, more smoke, and a greater need for preparation.



The full study was published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025EF006108" target="_blank" rel="noreferrer noopener">Earth's Future</a>.

Lightning will ignite even more wildfires as the climate heats up

Wildfires in the western U.S. have become a growing crisis. They’re lasting longer, burning hotter, and spreading into areas that rarely burned in the past. But another danger is rising, beyond heatwaves and droughts. Lightning - sudden, fierce, and incredibly powerful - is becoming one of the biggest wildfire risks.

<a href="https://www.earth.com/news/air-pollution-crime-behavior/">Air pollution</a> comes from many sources, from factories, to cars, to cigarette smoke. But when we think about air pollution, we generally think of the smog in major cities caused by heavy traffic and proximity to industrial factories. It’s not often that we consider the contributions of the day-to-day products we use.

But now, a new study led by the <a href="http://www.noaa.gov/">National Oceanic and Atmospheric Administration</a> (NOAA) has found that chemical products that contain certain compounds refined from petroleum – such as pesticides, paints, perfumes, and household cleaners, now rival motor vehicle emissions as the biggest source of urban air pollution.

Although people use about 15 times more fuel by weight than they do petroleum-based compounds in chemical products, these products contribute about as much air pollution as the transportation sector does. In particular, particle-forming emissions from chemical products – which contain tiny particles than can damage people’s lungs – are roughly twice as high as those from the transportation sector.

“As transportation gets cleaner, those other sources become more and more important,” says Brian McDonald, a scientist at the Cooperative Institute for Research in Environmental Sciences (CIRES) working in the NOAA’s Chemical Sciences Division, and lead author of the study. “The stuff we use in our everyday lives can impact air pollution.”

In this new assessment, researchers zeroed in on volatile organic compounds (VOCs), which can move into the atmosphere and react to produce either ozone or particulate matter. Both products of these reactions are regulated in the U.S. and other countries due to their health hazards.

The researchers assessed recent chemical production statistics gathered by industries and regulatory agencies, and made atmospheric chemistry measurements of the air in Los Angeles. They found that in the U.S., the amount of VOCs emitted by consumer and industrial products is actually two to three times greater than previously estimated by current air pollution inventories. 

They also determined that these same inventories overestimate vehicular sources of air pollution. The Environmental Protection Agency estimates that about 75 percent of VOC emissions come from vehicular sources, with the remaining 25 percent coming from chemical products. These new findings have the split closer to 50/50.

So why does this disproportionate air quality impact of chemical product emissions occur? It’s due in part to a fundamental difference between these products and fuels. 

“Gasoline is stored in closed, hopefully airtight, containers and the VOCs in gasoline are burned for energy,” explains Jessica Gilman, an atmospheric scientist at the NOAA and co-author of the paper. “But volatile chemical products used in common solvents and personal care products are literally designed to evaporate. You wear perfume or use scented products so that you or your neighbor can enjoy the aroma. You don’t do this with gasoline.”

Part of the reason that consumer and industrial chemical products have now been found to have this larger contribution is that, in recent years, cars have gotten cleaner. This means that we now have to focus our efforts on reducing emissions from these products in much the same way we did with cars. 

“It’s worked so well that to make further progress on air quality, regulatory efforts would need to become more diverse,” says Joost de Gouw, a CIRES chemist and co-author of the paper. “It’s not just vehicles any more.”

<a href="https://www.earth.com/news/self-driving-cars-sensors/">Autonomous vehicles</a> are quickly becoming more of a reality in the developed world, as some major companies have already put hundreds of vehicles on the road. This new technology could eventually save you the trouble of driving yourself everywhere, but could it also save the environment?

A new study published in the journal <a href="https://pubs.acs.org/journal/esthag">Environmental Science &amp; Technology</a> has found that the added weight, electricity demand, and aerodynamic drag of the sensors and computers used in these vehicles are major contributors to their lifetime energy use and greenhouse gas emissions. 

However, when savings from the driving efficiencies of autonomous vehicles are factored into these calculations, the net result is a reduction in lifetime energy use and greenhouse gas emissions of as much as 9 percent compared to conventional vehicles. 

“This study explored the tradeoffs between the increased environmental impacts from adding autonomous vehicle equipment with the expected gains in driving efficiency,” explains Gregory Keoleian, director of the Center for Sustainable Systems at the <a href="https://www.umich.edu/">University of Michigan</a> School for Environment and Sustainability, and co-author on the study.

In the study, the researchers assess the lifetime contributions of the sensing and computing subsystems in autonomous vehicles to energy use and greenhouse gas emissions. Autonomous vehicles – formally known as connected and automated vehicles (CAVs) – usually include multiple cameras, radar, sonar, LiDAR, a GPS navigation system, a computer, and support structures.

The vehicles the researchers analyzed for the study are Level 4 CAVs, which are vehicles that can operate without human input or oversight under select conditions. They assessed two types of CAVs: those powered by internal combustion engines and battery-powered electric vehicles. The two vehicle types were paired with sensing and computer subsystems of three sizes (small, medium, and large) to create six scenarios. To estimate lifetime energy use and greenhouse gas emissions for each scenario, they utilized life-cycle assessment methodology.

The results showed that autonomous vehicles with electric powertrains have 40 percent lower lifetime greenhouse gas emissions than vehicles powered by internal-combustion engines. “We’ve shown in this paper that a battery-electric vehicle is a better platform for CAV components compared to the internal-combustion engine vehicle in terms of minimizing environmental impacts,” says study lead author Jim Gawron, a graduate student at the U-M School for Environment and Sustainability and at the Ross School of Business.

Their findings also showed that the sensing and computing subsystems in CAVs could increase a vehicle’s energy use and greenhouse gas emissions by between 3 and 20 percent, as a result of increases in power consumption, weight, and aerodynamic drag. This includes the added weight and power demand of the onboard computer – roughly 45 percent of the weight and 80 percent of the power – and the drag caused by exterior-mounted CAV components. Luckily, the operational benefits of these vehicles are expected to outweigh these increases in the majority of cases. 

However, the conclusions of this study are based on the assumption that the operational efficiencies of CAVs can result in a 14 percent reduction in fuel consumption over conventional vehicles. But if the reduction ends up being significantly lower than 14 percent, the environmental benefits could disappear.

“Our findings highlight the need to focus on energy efficiency when designing autonomous vehicles so that the full environmental benefits of this emerging, transformative technology can be realized,” says Keoleian. “We hope this work contributes to a more sustainable mobility ecosystem.”

Autonomous vehicles would have environmental benefits

A new report from <a href="https://www.stanford.edu/">Stanford University</a> has revealed that global warming will lead to a higher frequency of extreme weather events, even if the global temperature goal set forth at the <a href="https://www.earth.com/news/country-paris-agreement/">Paris Agreement</a> is reached.

The research team analyzed historical climate data to estimate the probability of extreme weather events under two scenarios. The experts modeled future weather with a global average temperature increase of 1.5 to 2 degrees, which is the target agreed upon in Paris. They also modeled global warming of 2 to 3 degrees, which would be the outcome of commitments made by individual countries.

“The really big increases in record-setting event probability are reduced if the world achieves the aspirational targets rather than the actual commitments,” said co-author Noah Diffenbaugh. “At the same time, even if those aspirational targets are reached, we still will be living in a climate that has substantially greater probability of unprecedented events than the one we're in now.”

A previous study by the research team in 2017 demonstrated that human-induced global warming has increased the odds of record-setting hot events across more than 80 percent of the planet, while also promoting the occurrence of both wet and dry extremes. 

For the current study, the researchers expanded the number of climate models that they used to investigate the two different future global temperature rise scenarios. 

The researchers found that, if countries met their individual goals and limited warming to between 2 and 3 degrees, this would result in three times as many extremely wet days in North America, Europe, and East Asia. Record-breaking warm nights would increase by five times across half of Europe and 25 percent of Asia, and the number of hot days would likely increase as well.

If the Paris Agreement target is reached and global warming is limited to less than 2 degrees, regions of the world exposed to record-setting events would be reduced by as much as three times. Regardless, the world will likely experience more record-setting events than before, according to the study authors.


“Damages from extreme weather and climate events have been increasing, and 2017 was the costliest year on record,” said Diffenbaugh. “These rising costs are one of many signs that we are not prepared for today's climate, let alone for another degree of global warming.”


“But the good news is that we don't have to wait and play catch-up. Instead, we can use this kind of research to make decisions that both build resilience now and help us be prepared for the climate that we will face in the future.”

The study is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

Extreme weather will occur more frequently

A new report from Stanford University has revealed that global...

Researchers at the <a href="https://sydney.edu.au/">University of Sydney</a> have discovered a previously unknown connection between atmospheric <a href="https://www.earth.com/news/humans-avoid-carbon-dioxide/">carbon dioxide</a> cycles and the shifting amount of carbon dioxide stored in ocean crust.

The slow carbon cycle is the transfer of carbon between the Earth and the atmosphere. For tens of millions of years, this cycle has been driven by a series of chemical reactions and volcanic activity.

Hot, volcanic ocean crust is subject to weathering from the circulation of seawater through cracks and holes. The invasion of seawater allows minerals that capture carbon to gradually form within the ocean crust.

A recent study demonstrated that the temperature of the water at the seafloor makes a big difference throughout the weathering process. Ultimately, the hotter this water is, the more carbon dioxide gets stored in the ocean crust.

“To find out how this process contributes to the slow carbon cycle, we reconstructed the average bottom water temperature of the oceans through time, and plugged it into a global computer model for the evolution of the ocean crust over the past 230 million years,” explained study co-author Dietmar Müller. “This allowed us to compute how much carbon dioxide is stored in any new chunk of crust created by seafloor spreading.”


“Our plate tectonic model also allows us to track each package of ocean floor until it eventually reaches its final destination--a subduction zone,” said co-author Dr. Adriana Dutkiewicz. “At the subduction zone, the crust and its calcite are recycled back into the Earth's mantle, releasing a portion of the carbon dioxide into the atmosphere through volcanoes.”

The study revealed that the capacity of the ocean crust to store carbon dioxide changed consistently throughout time every 26 million years. Previous studies have documented 26 million-year cycles in other geological events as well including extinctions, volcanism, salt deposits, and atmospheric carbon dioxide fluctuations.

“Our model suggests that characteristic 26 million-year periodicity in the slow carbon cycle is instead driven by fluctuations in seafloor spreading rates that in turn alter the capacity of the ocean crust to store carbon dioxide,” said Miller. “This raises the next question: what ultimately drives these fluctuations in crustal production?”

Gaining a better understanding of the slow carbon cycle is critical for predicting how the Earth will respond to rising atmospheric carbon dioxide that results from human activities.

The study is published in the journal <a href="http://advances.sciencemag.org/">Science Advances</a>.

Slow carbon cycle driven by weathering on the seafloor

Researchers at the University of Sydney have discovered a previously...

<a href="https://www.earth.com/news/rare-species-tropical-forests/">Tropical forests</a> are a crucial ecosystem that hold more than half all of the species in the world. These lush forests also play an important role in the carbon cycle by absorbing and storing carbon dioxide from the atmosphere. 

However, tropical forests around the world have diminished dramatically, particularly due to forest fragmentation, which is the process of breaking apart or splitting up large swaths of forest into smaller pieces. 

Now, a new study by researchers from the <a href="https://www.ufz.de/index.php?en=33573">Helmholtz Centre for Environmental Research</a> (UFZ) has calculated the amount of tropical forest fragmentation across the globe.

Their findings, published in the journal Nature, show how tropical forest fragmentation in Africa, Central and South America, and Southeast Asia is at a critical tipping point. If tropical forest fragmentation continues at its going rate, it will decrease biodiversity and carbon storage capacity.

In order to reach this conclusion, the researchers first had to find a way to measure and analyze patterns of forest fragmentation around the world. 

Remote sensing data was used to quantify forest cover in the tropics from which the researchers found more than 130 million forest fragments. All three continents showed consistency in frequency and size of fragments. 

The reason for this similarity has to do with the power law in physics and the percolation theory. 

“This theory states that in a certain phase of deforestation the forest landscape exhibits fractal, self-similar structures, i.e., structures that can be found again and again on different levels,” said Andreas Huth, the leader of the research. 

The remote sensing data was compared to different predictions of the percolation theory, and the results showed that fragmentation could be calculated with the theory. As the calculations matched the data in size distribution, fractal dimension, and length distribution of the fragment edges. 

The researchers also found that the percolation theory could be used to predict future fragmentation over the next decade. At its current rate in Central and South America, the number of fragments will increase 33 fold, and the fragments will only get smaller and smaller. 

Forest fragmentation is a major concern for several reasons. The loss of habitat will affect biodiversity and many rare species could go extinct. The loss of forest cover could increase carbon emissions thereby worsening the impacts of climate change. 

The new data allows researchers to measure and predict global tropical forest fragmentation, which could help dictate future policies and conservation efforts.

Scientists are warning that an underwater supervolcano off the coast of Japan may be building toward a massive eruption. The Kikai Caldera, which is submerged just south of Kyushu Island, is responsible for one of the most explosive supereruptions of the last 10,000 years.

Researchers at the <a href="http://www.k-obec.kobe-u.ac.jp/">Kobe Ocean-Bottom Exploration Center</a> (KOBEC) have found evidence that the Kikai volcano is collecting lava in its 6.2-mile-wide dome. 

The giant dome appears to be growing and already contains approximately 7.68 cubic miles of <a href="https://www.earth.com/news/philippines-volcano-spewing-lava/">lava</a>. The KOBEC team confirmed that this dome was created after the volcano’s earth-rumbling eruption 7,300 years ago.

Six of the samples collected at the caldera site since 2015 turned out to be rhyolites, which form during the cooling of lava or magma. In addition, the scientists documented several intrusions on the dome’s surface, indicating the presence of lava.

The experts also observed bubbling gas and superheated water columns in the vicinity. The team made these observations using underwater robots, underwater seismographs, and by collecting and analyzing rock samples.

On their next mission, the scientists will use seismic reflection and underwater robots to explore how the caldera formed and to investigate what leads up to a massive caldera eruption. The researchers will also attempt to capture high resolution images of magma build-up in the Earth’s crust.

Yoshiyuki Tatsumi is a magma specialist at KOBEC and the study's first author. Professor Tatsumi told <a href="https://mainichi.jp/english/">The Mainichi</a> , “Although the probability of a gigantic caldera eruption hitting the Japanese archipelago is 1 percent in the next 100 years, it is estimated that the death toll could rise to approximately 100 million in the worst case scenario.”

Experts fear that the Kikai Caldera could erupt without warning. They say the event could significantly alter the climate, triggering a volcanic winter.

In an effort to speed up the construction of his proposed wall across the Mexican border, <a href="https://www.earth.com/news/trump-cut-clean-energy/">President Trump</a> is waiving over 30 environmental regulations. He has also announced a new infrastructure plan that will make building permits easier to acquire despite any environmental threats that may be posed by the projects.

As he unveiled the White House’s $200 billion dollar infrastructure proposal, President Trump promised to “speed the permit approval process from 10 years to two years, and maybe even to one year.” Trump intends to limit environmental reviews of building projects to 21 months and hopes to restrain federal agencies from objecting to new construction.

Twenty-eight environmental organizations, including the Animal Welfare Institute, issued the following joint statement:

“President Trump’s proposal is an unprecedented giveaway to the wealthy and powerful that would allow his administration and its special interest allies to unilaterally sidestep bedrock conservation, public health, and worker safety laws that keep our families and communities out of harm’s way.”

Conservationists are also outraged that the Trump administration is attempting to evade critically significant policies to construct the border wall including the National Environmental Policy Act, the Endangered Species Act, and the Clean Water Act.

The Department of Homeland Security claims that there is an immediate need for the wall, specifically to stop a large amount of illegal entry in El Paso.

A notice published in the government's Federal Register stated: “The Secretary of Homeland Security has determined, pursuant to law, that it is necessary to waive certain laws, regulations and other legal requirements in order to ensure the expeditious construction of barriers and roads in the vicinity of the international land border of the United States.”

The Center for Biological Diversity is reporting that the border wall threatens the habitats of dozens of species. The nonprofit organization is considering taking legal action against the construction of the wall for the second time.

Researchers at <a href="https://www.rockefeller.edu/">Rockefeller University</a> have quite literally made a groundbreaking discovery. While analyzing soil samples from all over the United States, the experts found a new class of antibiotics that may be capable of killing strains of bacteria which have become drug resistant, or <a href="https://www.earth.com/news/hospital-superbugs-antibiotic-resistant/">superbugs</a>.

Antibiotics and other microbial agents have saved millions of lives over the last 70 years, but the rapid emergence of antibiotic-resistant bacteria has become a global crisis.

According to the <a href="https://www.cdc.gov/">Centers for Disease Control and Prevention</a> (CDC), over 2 million people are infected with antibiotic-resistant bacteria every year in the United States, and at least 23,000 of those infected die as a direct result.

Globally, at least 700,000 people die each year as a result of drug resistance, and that number is predicted to reach 10 million by the year 2050.

Dr. Sean Brady is a researcher and microbiologist at Rockefeller University and lead author of the current study. Dr. Brady and his team set out to investigate the bacteria and microorganisms abundantly found in soil.

“Every place you step, there’s 10,000 bacteria, most of which we’ve never seen,” Dr. Brady told <a href="https://www.washingtonpost.com/">The Washington Post</a>. “Our idea is, there’s this reservoir of antibiotics out in the environment we haven’t accessed yet.”

The researchers used a gene sequencing technique to analyze over 1,000 soil samples contributed by scientists from all over the United States. One sequence contained a gene with a known association to the production of calcium-dependent antibiotics.

The team cloned the DNA and cultured it, and the microorganisms began producing the new antibiotics which were named malacidins. 

The team tested the compounds on rats with methicillin-resistant Staphylococcus aureus (MRSA) and found that the malacidins successfully killed the infections. The team will now investigate whether the antibiotics are safe for humans.

Dr. Brady told the <a href="https://www.bbc.co.uk/">BBC</a>: “It is impossible to say when, or even if, an early stage antibiotic discovery like the malacidins will proceed to the clinic. It is a long, arduous road from the initial discovery of an antibiotic to a clinically used entity.”

The study is published in the journal <a href="https://www.nature.com/nmicrobiol">Nature Microbiology</a>.

Researchers at Rockefeller University have quite literally made a groundbreaking...

Researchers at <a href="https://www.wvu.edu/">West Virginia University</a> are reporting that songbird populations in the central Appalachian Mountains are struggling with a greater presence of shale gas development. An investigation has revealed that the nesting success of the Louisiana Waterthrush, in particular, has declined at sites impacted by the extraction of natural gas.

The most rapid growth of hydraulic fracturing in the country is taking place in northwestern West Virginia. Prior to this study, little was known about how this <a href="https://www.earth.com/news/shale-gas-inefficient-electricity/">shale gas</a> industry boom may be affecting bird populations in the region.

A team of researchers led by Mack Frantz mapped territories of the waterthrush and monitored nests along 14 streams from 2009-2011 and also from 2013-2015. Using aerial photographs and satellite imagery, the experts measured disturbances to both the streams and the forest canopy, and then determined which of these disturbances were caused by shale gas development.

The results of the study showed that nest survival and reproductive success declined as shale gas development expanded. Experts also noted that the size of individual waterthrush territories increased, which indicates that the birds had to range farther in order to access a sufficient amount of resources.

“I hope our findings lead to robust protections of our forested headwater stream ecosystems, which are currently overlooked for regulation despite their critical role in providing nutrients and organic matter downstream, not to mention as an important source for drinking water,” said Frantz. 

“Waterthrushes are a modern-day 'canary in the coal mine,' and there are many more opportunities to study how anthropogenic disturbance affects and entangles food webs at the aquatic-terrestrial interface.”

The study is one of the first to demonstrate that shale gas development can affect songbird reproductive success and productivity. Leesia Marshall is a waterthrush expert who was not involved in the research. 

“This paper should serve as a call for all scientists to redouble efforts across all related disciplines to document the present impacts of shale gas extraction and to develop strategies for mitigation and avoidance of potential impacts in the future,” said Marshall.

The study is published in <a href="http://americanornithologypubs.org/loi/cond">The Condor: Ornithological Applications</a>.

According to a new study from the <a href="https://www.york.ac.uk/">University of York</a>, carefully managed fire can optimize mammal and bird diversity in African savannas. 

The research, which is the first of its kind to examine the “pyrodiversity" of an entire continent, revealed that this strategy can improve the number of mammal species by 20 percent and the number of bird species by 30 percent with adequate rainfall.

“Fire is often viewed as homogeneous, but in reality there is a range of different fires characterized by variation in size, intensity, season and frequency of burning,” said lead author Dr. Colin Beale. “We found that in wet savanna increasing the range of different types of fire in an area allows a wider number of species to thrive.”

“Fire is widely thought to have a negative impact on the environment, but in African savannas hominids have been setting a variety of fires for around a million years so fire is something the ecosystem has co-evolved with and adapted to.”

The researchers gathered 15 years of satellite data on fires and accessed distribution maps of all the bird and mammal species in protected areas across <a href="https://www.earth.com/news/african-savannahs-climate-change/">Africa's savannas</a>. The study revealed that savannas with abundant rainfall and the most varied types of fire contained significantly more bird and mammal diversity.

The experts found that a range of fire types allowed rare species of birds, such as the Rufous-tailed Weaver and the Black-bellied Sunbird, to cohabitate with more common bird species. The study findings indicate that fires alter the conditions within savanna habitats and increase the availability of nutrients, terrain, and shelter for a greater number of species to thrive.

As a result of the investigation, the researchers hope to provide land managers and conservationists with guidance on how to use carefully managed fire as a tool to boost biodiversity.

“Pyrodiversity is particularly important for biodiversity in wet savanna landscapes, but this isn't the only reason people light fires: different goals require different burning patterns,” said Dr. Beale. “We want to develop tools to help the managers of conservation areas articulate what they want to achieve and help them to use fire to do it.”

The study is published today in <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1461-0248">Ecology Letters</a>.

<a href="https://www.earth.com/news/deadly-heatwaves-rise-emission/">Heat stress</a> can have a devastating effect on plant growth and development, and can greatly reduce crop yields. Researchers at the <a href="https://www.cam.ac.uk/">University of Cambridge</a> set out to gain a better understanding of how plants sense and respond to heat stress.

Plants respond to heat differently during the day compared to night time, and plants have a much better chance of survival when they are exposed to heat during the day. This is because they have adapted a cycle of resistance that helps them to endure the hottest hours of the day.

Plants use their sense of temperature to activate the production of protective heat shock proteins (HSP), yet the signaling process involved in this activation process is a mystery. Previous research has indicated that heat resistance is triggered in plants when they are exposed to light and then deactivated in the darkness.

“I was quite interested in how plants respond to their environment and was surprised that there was so much to be learned about how plants sense and respond to temperature,” said study co-author Patrick Dickinson. “There is a lot known about how plant and animal cells respond to extreme heat stress, but not much was known about their response to ambient heat or how they regulate their response to heat between day and night."

Dr. Dickinson found that chloroplast genes are linked to plant stress response. He discovered that the chloroplast sends a signal in response to light, and this signal activates gene expression in the nucleus which protects the plant from heat stress.

“There is some sort of signal coming initially from the photosynthetic electron transport chain, which is communicated to the nucleus to activate the gene expression, but what that signal is is not clear yet,” explained Dr. Dickinson.

“It could possibly be hydrogen peroxide because that has been shown to move from the chloroplast to the nucleus to initiate signalling, but there is still a lot more that needs to be looked at to confirm the nature of the signalling.”

Study supervisor Dr. Phil Wigge stressed the importance of identifying the genes that are involved in the heat resistance of plants.

“Many of the crops being grown around the world today are already being grown at the top of their comfort zone in terms of temperature,” said Dr. Wigge. “There is actually an estimate that for major crops like wheat, rice and maize, that every degree Celsius rise in temperature above current temperatures could potentially decrease crop yields by between 3-7% due to thermal stress.”

“The contribution that we are trying to make in the lab is to understand the molecules and the underlying mechanisms that control how a plant senses temperature and the genes that are required for a plant to adapt to higher temperatures. And we hope that we can then use that information to discover the same genes in crop plants and see if those genes can be used to make crop plants more resilient to heat stress."

The study is published in the journal <a href="http://www.cell.com/cell-reports/home">Cell Reports</a>.

How plants protect themselves from heat stress

Heat stress can have a devastating effect on plant growth...

A new study has found that contrary to many previous climate studies, lightning strikes will occur much less frequently even under the worst case climate change scenarios where temperatures increase by five degrees Celsius by the year 2100. 

Researchers from the Universities of <a href="https://www.ed.ac.uk/">Edinburgh</a>, <a href="http://www.leeds.ac.uk/">Leeds</a>, and <a href="http://www.lancaster.ac.uk/">Lancaster</a> found that many <a href="https://www.earth.com/news/worst-case-climate-unlikely/">climate change</a> studies that project an increase in lightning strikes don’t take into account the decrease in cloud ice. 

Climate change is predicted to increase storms and extreme weather events, cause drought, wildfires, heat waves, and sea level rise as well as habitat degradation and coastal flooding. 

However, in a new study published in the journal Nature Climate Change, the researchers found that decreased cloud ice due to increased temperatures will likely lead to a 15 percent decrease in lightning strikes. 

As tiny ice particles form and move within the clouds, it builds up an electrical charge in the particles. When it rains or storms, the release of the particles causes the electrical charge to create lighting and thunder.

For the study, the researchers created a method that calculated cloud ice and factored in the cloud ice relationship on future lightning strikes under worst-case scenario conditions. 

Fewer lightning strikes mean fewer natural wildfires and damage to power lines and buildings. 

According to the <a href="http://www.dailymail.co.uk/sciencetech/article-5381867/Global-warming-reduce-lightning-strikes.html">Daily Mail</a>, in the US alone lightning strikes cause anywhere between $5 to $6 billion in damage each year.

The results show how worst-case scenarios and climate change projections, while important to understanding the effects of warming temperatures, don’t always consider all the factors that should be accounted for. 

“'In previous studies of the impact of climate change on lightning, researchers often didn't include consideration of changes in cloud ice,” Declan Finney, a member of the researcher team, told <a href="http://www.dailymail.co.uk/sciencetech/article-5381867/Global-warming-reduce-lightning-strikes.html">Daily Mail</a>.  “This research questions the reliability of previous projections of lightning, and encourages further study into the effects of climate change on cloud ice and lightning.”

<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.

<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.

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.

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">

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."
