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.

During the Eocene epoch in the Paleogene period, an asteroid collided with Earth that caused the highest temperatures ever felt on the planet.

According to new research, the event caused cubic zirconia to form, meaning temperatures must have reached 2,370 degrees Celsius or higher. 

The collision formed the Mistastin Lake crater in Canada, which measures over 17 miles in diameter. This study was a revolutionary one as it used the presence of zirconia and rock melt in the Mistastin Lake crater in Canada to measure temperatures at the time of the impact. 

“Nobody has even considered using zirconia as a recorder of temperatures of impact melts before. This is the first time that we have an indication that real rocks can get that hot,” Dr. Nicholas Timms, lead author of the research, told <a href="https://www.newscientist.com/article/mg23531433-600-found-the-hottest-place-ever-found-on-earths-surface/">New Scientist</a>. 

Researchers from <a href="http://www.curtin.edu.au/">Curtin University</a> in Australia and <a href="https://www.westernu.edu/">Western University</a> in Ontario conducted the study that examined how the Earth’s crust was shaped and changed after collisions with rocks from space.

Calculating exact temperatures during early <a href="https://www.earth.com/video/spot-asteroids-earth/">asteroid</a> strikes was difficult, as many rocks and minerals evaporate in extreme heat. But the formation of zirconia and its presence in the crater sheds new light on what conditions were like billions of years ago. 

The new study will help geologists and scientists gain a better understanding of what Earth was like during its early periods, and sheds new light on the impact of asteroid strikes.

The queen conch, famous for its majestic shell, is on the decline, threatening local fisheries in the Caribbean. The high demand for queen conch has now led to a trade restriction by the <a href="https://www.cites.org/eng/disc/what.php">Convention on International Trade in Endangered Species of Wild Fauna and Flora</a>. 

Several countries have even closed their queen conch fisheries in order to help the conservation of the species. But scientists and conservationists have struggled to find the best ways to revitalize conch populations. 

But now, new research has found that the key to recovering queen conch populations lies in understanding the wide variance within the species. Looking at the queen conch as one mass group doesn’t aid the species, as conch are unlikely to travel to rehabilitate other areas of the ocean. 

Researchers even discovered distinct genetic differences among isolated pockets of queen conch, suggesting that there is very little mingling or mixing among them. 

Understanding how the conch are fragmented throughout the Caribbean is a necessary first step to finding and implementing effective <a href="https://www.earth.com/news/spiritual-beliefs-animals-conservation/">conservation</a> efforts. 

An international team of collaborators, led by researchers from the Smithsonian's<a href="https://marineconservation.si.edu/"> Marine Conservation Program</a>, conducted a study that gathered data on 19 different queen conch sites in the Caribbean to see how local subpopulations fared. 

The study was published in the journal Diversity and Distributions. 

Researchers collected a tissue sample from 643 different conches spanning from the United States to the Bahamas. A DNA analysis of the samples revealed that there were differences in the conch genomes.

“This tells us is that it's not just one giant, well-mixed population of queen conch throughout the entire Caribbean. If you're in two sites that are not well connected by ocean currents, the chances of your queen conch populations being connected and interrelated are pretty low,” said Nathan Truelove, a postdoctoral researcher at the <a href="https://www.sms.si.edu/">Smithsonian Marine Station</a>. 

The results of the study show that conservation efforts will have to be tackled at local levels, and that treating the species as one intertwined group with blanket management techniques could prove ineffective.

Research from <a href="http://harvardforest.fas.harvard.edu/">Harvard Forest</a> has revealed that the New England states are losing forests at a rate of 65 acres per day. Public funding for land protection has dropped by 50 percent in all six New England states since 2008, and funding for land conservation is not too far behind in its decline.

"The incremental chipping away of forest and farmland by scattered development is hard to see day-to-day but it adds up over time and represents a significant threat to the region," said David Foster, Director of the Harvard Forest. "If we stay on the current path, we'll lose another 1.2 million acres of open land by 2060."

Once land is developed, it is no longer productive and all of its invaluable benefits such as local wood and climate protection are sacrificed. The researchers published a report which provides the most up-to-date and comprehensive data available on land use trends in the region. It is the third in the “Wildlands and Woodlands” series of publications authored by the team. 

The previous reports defined a regional goal of conserving 30 million acres of <a href="https://www.earth.com/news/local-strategies-protecting-rainforest/">forest</a> and all remaining farmland. The latest report outlines the progress that has been made toward achieving this vision. The scientists also point out that land conversion is even more of a short-term threat to New England's forests than climate change

"When we look specifically at forests in New England, it is clear that the impacts of land use will be far greater than those of climate change over the next 50 years," said co-author Jonathan Thompson. "This may seem counter-intuitive given the major threat that climate change poses to all sectors of society. But climate change slowly alters the health and types of trees that grow whereas conversion eliminates forests altogether."

Despite the current trends, the authors of the report say that it is still possible to reach their goals. To do this, they have outlined a plan of which calls for actions such as tripling the pace of conservation and putting more land to work for sustainable farming and forestry.

Soil reclamation is a method of recovering the natural balance of soil. After the installation of natural gas wells, for example, soil reclamation efforts are key in to bringing the soil back to a restored state of health. An extensive study on soil reclamation in Wyoming has shown that the effectiveness of reclamation is often obstructed by salt-affected soils, weed invasions, and slow plant establishment.

Jay Norton is a researcher in Soil Science, Agronomy, and Environmental Sciences at the <a href="http://www.uwyo.edu/">University of Wyoming</a>. Norton has been analyzing soil reclamation at three Wyoming production areas, including nine natural gas drilling sites, over seven years. 

The study revealed that organic <a href="https://www.earth.com/news/survey-americans-support-carbon-tax/">carbon</a> returned to pre-disturbance level in approximately eight years at the site where the soil carbon content was most abundant before drilling started. In more dry and saline sites, however, organic carbon remained lower than pre-disturbance levels in the same time frame. 

Next, Norton will examine the conditions needed to re-establish native vegetation at the sites, which may be influenced by climate.

Norton’s soil restoration research will be presented at the <a href="https://www.acsmeetings.org/">Managing Global Resources for a Secure Future</a> annual meeting in Tampa, Florida, as "Soil Changes Before, During, and After Natural Gas.” This important topic will be addressed at the convention on Monday, October 23rd. 

The meeting is sponsored by the <a href="https://www.agronomy.org/">American Society of Agronomy</a>, Crop Science Society of America, and the Soil Science Society of America.

Known as The Great Oxidation Event, the Earth’s atmosphere was filled with oxygen over a period of just 200 million years. This, according to new research published in the journal Nature Geoscience.

Before The Great Oxidation, the Earth had no free oxygen, or oxygen that wasn’t bound to other elements. 

Scientists have long wondered how the Earth could have oxidized so drastically in so little a time frame, and now geologists from the <a href="https://www.ubc.ca/">University of British Columbia</a> (UBC) have found a probable answer. 

Small pockets of free oxygen began to pop up around three billion years ago, but UBC researchers Matthijs Smit and Klaus Mezger believe the Great Oxidation Event occurred because of the evolution of the earth’s continental crust. 

The changing composition of continental rocks suddenly gave way to large quantities of <a href="https://www.earth.com/news/ocean-deoxygenation-history-repeating/">oxygen</a> that was just waiting for the right conditions.

“Oxygenation was waiting to happen. All it may have needed was for the continents to mature,” said Smit.

Smit and Mezger felt that the composition of continental rocks, which they knew had changed during the same time as The Great Oxidation, might be linked to oxygen filling the atmosphere. 

The researchers gathered data from geological records, looking at shales and igneous rocks dating as far back as billions of years. 

Early earth’s continental rocks were rich in magnesium and low in silica. The rocks also contained olivine, a mineral that when in contact with water consumes oxygen and locks it up. 

As the continental crust changed over the years, its composition evolved to exclude olivine. Since the olivine wasn't around to consume all the oxygen, the oceans became saturated and oxygen was free to fill the atmosphere. This in turn allowed an abundance of life to thrive on the planet. 

"It really appears to have been the starting point for life diversification as we know it. After that change, the Earth became much more habitable and suitable for the evolution of complex life, but that needed some trigger mechanism, and that's what we may have found,” said Smit. 

The researchers still aren’t sure exactly what caused the composition of the earth’s continental crust to shift, a question that will require further research to answer. But Smit and Mezger have helped shed light on how the Earth’s geological makeup evolved to allow human life to exist.

Millions of tons of <a href="https://www.earth.com/news/worlds-tap-water-contains-plastics/">plastic</a> particles are buried in the oceans every year as a result of human activities. Researchers have determined that the best strategy to eradicate some of this pollution may be to appeal to the public's love of the sea. 

Scientists are exploring ways to slow down the amount of plastic pollution that is accumulating in the ocean. They are searching for strategies to recover the health of our seas, and striving to protect all of the human benefits associated with healthy oceans.

Researchers from the <a href="https://www.plymouth.ac.uk/">University of Plymouth</a> and the <a href="https://www.surrey.ac.uk/">University of Surrey</a> looked at the history of how public pressure can lead to policy change. For example, public opposition led to bans on the use of microbeads in cosmetics and helped place restrictions on single-use plastic bags.

The researchers say that these types of public efforts are steps in the right direction, but they are not addressing the underlying issues. Their report, published in the journal <a href="http://www.nature.com/nathumbehav/">Nature Human Behaviour</a>, explains that there needs to be a more unified and interdisciplinary approach.

Dr. Sabine Pahl is an associate professor of Psychology and lead author of the report.

"The public's love of the coast is obvious, so it stands to reason that they would play a role in preserving its future,” said Dr. Pahl. “Plastic pollution is a problem for all in society and while there are solutions out there, they must be socially acceptable as well as economically and technically viable. We need to work together across disciplines and sectors to build on the strength of humans to facilitate change."

The authors of the report conducted previous studies which revealed the negative impact of marine litter on coastal environments. As a result of the current study, they compare ocean plastic pollution to other environmental threats like marine litter, where the symptoms occur some distance away from land-based causes.

"From previous research we know that people appreciate and value the importance of the ocean and see marine litter as a global problem,” said co-author Dr. Kayleigh Wyles. “Yet, the challenge is connecting the dots. So many of our behaviors and decisions contribute to this problem, but at those particular points of time, we often don't think of how they can impact the environment.” 

Dr. Wyles added, “Using behavioral sciences to understand drivers of human behavior will therefore help support ongoing initiatives that can look to clean up our environments."

Europe has twice as many diesel vehicles as the rest of the world combined, and it could be taking a bigger toll on public health than previously believed.

A team of researchers from the <a href="http://www.iiasa.ac.at/">International Institute for Applied Systems Analysis</a> in Austria, <a href="http://www.chalmers.se/en">Chalmers University of Technology</a> in Sweden and the <a href="https://www.met.no/en">Norwegian Meteorological Institute</a> have conducted a new study to find out how the air pollution produced by diesel vehicles in Europe may contribute to the annual pollution-related deaths on the continent. 

They found that emissions from diesel cars, trucks, buses and other vehicles may be linked to as many as 10,000 premature deaths per year. Half of those deaths may have been prevented if laboratory testing of diesel vehicle emissions had been accurate, the scientists said.

“Modern engine controls have been optimized by manufacturers for the specific laboratory testing but underperform in real-driving,” the scientists said, referring to <a href="https://www.earth.com/news/vehicle-emissions-worse-testing/">earlier research on diesel emissions</a>.

About 425,000 deaths in Europe are linked to air pollution each year, the researchers said in a press release. The vast majority of those deaths – about 90 percent – stem from cardiovascular or respiratory diseases linked to nitrogen dioxide and nitric oxide, abbreviated NOx, the scientists said.

The problem is exacerbated by Europe’s large number of diesel cars, trucks and other automobiles. Diesel vehicles have been found to produce up to <a href="https://www.earth.com/news/nitrogen-oxide-diesel-car/">10 times more NOx than buses</a> despite being substantially smaller.

"If diesel car emissions were as low as petrol car emissions, three quarters or about 7,500 premature deaths could have been avoided," said Dr. Jens Borken-Kleefeld, a transportation expert for the IIASA.

The vast majority of the premature deaths are in France, Germany and Italy, the researchers said. However, due to other types of air pollution and other environmental factors, the risk per capita is much higher in northern Italy, they said.

The study will be published in the journal <a href="http://iopscience.iop.org/erl">Environmental Research Letters</a>.

Research has found that many people who deny climate change are weary of how environmental regulations would negatively impact them financially, particularly in the oil and coal sectors. But a recent study has found that not addressing <a href="https://www.earth.com/news/climate-change-reduce-coffee/">climate change</a> as a major catalyst for severe weather will end up costing 5 times more. 

The study, titled Project Metropolis, examined Santos, a coastal city in Sao Paulo, and defined the minimum costs the city would have to factor in to prepare for rising sea levels due to climate change. 

Project Metropolis estimated that Santos would have to pay around 300 million (Brazil Real Equals) in renovations to be better prepared for climate change. Conversely, not doing anything to adapt to warming temperatures could cost the city billions. 

Researchers also note that there are other sectors besides real estate, like health and education, that would be greatly impacted by climate change

The team also examined a wide range of climate change research and predictions to get a more detailed understanding of the costs. The model looked at rising sea levels, tides, predicted rises in storm surges, extreme weather events, and coastal flooding. 

There is no question that sea levels will rise, it’s simply a matter of how high. 

“We identified two possible scenarios for the city. One is more realistic, with sea levels rising by 0.36 cm per year. The other is the worst-case scenario, with sea levels rising by 0.45 cm per year,” said Celia Regina de Gouveia Souza, a researcher at the <a href="http://www.igc.usp.br/">Geologic Institute (IG) of the Sao Paulo State. </a>

Once the researchers had an accurate estimation of rising sea levels and the costs of climate change, they presented their findings to the general public and local government. The people of Santos opted to implement changes to hinder the effects of climate change. 

“The measures chosen by the public were quite adequate. We hope the project will continue under the aegis of the local authorities with ongoing popular participation. If so, the worst-case scenario is much less likely to materialize," said Luci Hidalgo Nunes, a researcher at <a href="http://www.unicamp.br/unicamp/">The University of Campinas </a>

Project Metropolis is an innovative approach to affecting climate change. Not only does it create a dialogue among the public and policymakers, but the research inconclusively presents the costly ramifications that the city and people would face if no changes were adopted.

Fall is in the air, and it is the perfect time of year to enjoy the great outdoors. According to the <a href="https://www.rvda.org/RVDA/Media/News_Releases/2017_News_Releases/March_2017/Camping.aspx">2017 North American Camping Report</a>, 75 million households in the United States are active campers. Half of those families say they plan to <a href="https://www.earth.com/video/insomnia-cure-camping/">camp</a> more this year. 

Whether you are an experienced camper or just someone that looks forward to pitching a tent every now and then, it is simple to get outside and enjoy the beauty of nature. The following is a list of the 8 most amazing places to camp in the United States.

Glacier National Park 

Located in Montana on the US/Canada border, this park features more than a million acres, including mountains that began forming 170 million years ago. Featuring 130 named lakes, over 1,000 different species of plants, and hundreds of species of animals, this is one of the prime locations in the country to experience life outside.

Acadia National Park

With its 17 million acres of forest, 6,000 lakes and ponds, and 32,000 miles of rivers and streams, Maine has an abundance of biodiversity. Located on Mount Desert Island, this park encompasses everything the state has to offer including Cadillac Mountain, an incredible hiking spot that towers over the site at 1,530 feet.

Little Tybee Island

Just a short boat ride south of Tybee Island, Georgia, this is the perfect spot to sleep under the stars. The island has a number of endangered species of birds, rich salt marshes, and natural dunes. This wildlife reserve is twice the size of Tybee, yet completely uninhabited.

Shenandoah National Park

This breathtaking site in Virginia is only a short drive from Washington D.C. that features over 500 miles of hiking trails with access to gorgeous waterfalls and stunning views. One of the most popular trails is a nine-mile hike to Old Rag Mountain, which sits high in the Blue Ridge Mountains.

Badlands National Park  

Known for an abundance of fossil mammals, this historic area of South Dakota offers a number of great camping sites. The terrain is rugged and not the easiest to navigate, but the experience is well worth the extra effort. The Badlands are said to have the largest fossil accumulation from the Eocene and Oligocene Epochs.

Yosemite National Park

This park, located in the Sierra Nevada mountains of California, is known for its ancient sequoia trees, granite cliffs, clear streams and an incredible amount of biodiversity. Yosemite features 13 campgrounds, and the site is so iconic that it was key in the concept of national parks. 

Crater Lake National Park

Located in Oregon among the Cascade Mountain Range, this is the site of incredible volcanic formations, including Crater Lake. This lake is the deepest in the United States and is also said to be the cleanest and most pure lake in the country. The park has two developed campgrounds.

Pisgah National Forest  

This enchanted forest is known as the Land of the Waterfalls. It encompasses 500,000 acres of the Appalachian Mountains just outside of Asheville, North Carolina. Mile-high peaks offer majestic views and campers can enjoy rock climbing, backpacking, and fishing.

Ludington State Park

Located in western Michigan, Ludington State Park spans 5,300 acres and just last year celebrated its 80th birthday. Known as the most popular state park in Michigan, Ludington attracts a large number of tourists due to its widely diverse attractions, which include hiking, fishing, biking, boating, swimming, and sledding.

Arches National Park

Located in eastern Utah next to the Colorado River, Arches National Park contains over 2,000 natural sandstone arches across 76,000 acres. The majestic beauty and vibrant orange and red colors make the park a favorite for those most familiar with the southwestern United States. Although climbing on the named arches is strictly prohibited, climbing is allowed in other parts of the park, along with hiking and camping. Arches is also a popular destination for astronomers, thanks to its uniquely clear skies.

The 10 best camping sites in the United States

Fall is in the air, and it is the perfect...

Experts have determined that one-third of Asia’s glacier ice will vanish by the end of the century regardless of the 1.5-degree Celsius global warming target established in Paris. These mountain glaciers contribute to the water supply of millions of people, and losing this amount of glacier mass will have an enormous impact.

Researchers from the Netherlands set out to determine what would happen to the mountain <a href="https://www.earth.com/news/montana-glaciers-quickly-disappearing/">glaciers</a> in Asia if global warming exceeded 1.5 degrees Celsius by the end of the century. Their investigation revealed that climate change at the current rate could diminish the glacier ice by two-thirds.

“These projections have potentially serious consequences for regional water management and mountain communities,” said the researchers. The authors of the study also warned that the 1.5 -degree Celsius goal “is extremely ambitious and is projected by only a small number of climate models.” 

Philip Kraaijenbrink is a geographer at the <a href="https://www.uu.nl/en">University of Utrecht</a> who led the study.

“In regions where glacier melt water is an important part of the river flow, the retreating glaciers can become a problem,” said Kraaijenbrink. He explained that there are many people depending on rivers such as the Indus and Ganges that originate high in the Asian mountains.

“In these basins, the river water is used for irrigation of cropland, drinking water and for hydropower dams,” said Kraaijenbrink.

Comparisons of over 100 climate simulations showed that Asia's mountain glaciers often experience temperatures warming at a higher rate than the global average. With the exception of the Kunlun Mountains in China, all of the mountain glaciers examined in the study were losing mass.

The study revealed that the disappearance of glacier ice is nearly proportionate to the amount of warming in this region, with some exceptions. The research is published in the journal <a href="http://www.nature.com/nature/">Nature</a>.

Older fish are an important part of the ecosystem, similar to older <a href="https://www.earth.com/news/tropical-trees-weapon-climate-change/">trees</a>, because fish who have aged longer might occupy a different geographical area, might try a different food source, and may become a more dominant predator in some cases. 

“More age complexity among species can contribute to the overall stability of a community. If you trim away that diversity, you're probably reducing the marine food web's ability to buffer against change,” said Lewis Barnett, lead author and a UW postdoctoral researcher at the School of Aquatic and Fishery Sciences and the <a href="http://jisao.washington.edu/">Joint Institute for the Study of the Atmosphere and Ocean</a>.

Older fish also help keep the food chain fresh and can reproduce more over their lifetime. 

“I think of old fish as an insurance policy -- they get you through those periods of bad reproduction by consistently producing eggs,” said Trevor Branch, co-author and a UW associate professor. 

Fishing operations  have regulations on the volume of fish they can catch, but don’t have any regulations on age or size. As a result, most fish aren’t allowed to go through a natural life cycle. The longer a fish lives, the more likely it will be caught. 

There also certain environmental factors at play, like disease and pollution, that can contribute to the decrease in older fish. 

The researchers gathered data from commercial and recreational fisheries that detailed the status of changing fish populations over the years. The results show that of the 63 populations of fish analyzed, the proportions of fish in the older age brackets had declined from 79 percent to 97 percent. 

The surprising results will hopefully help dictate future policy for fisheries and fishing operations. 

The researchers suggested several methods for changing fishing operations to help balance out fish populations, including barring fish of a certain size or age from being caught and closing off certain areas to fishing permanently.

More and more studies are showing that access to safe, natural environments improves the overall health of children including heart health, mental health, weight management, and stress management. A new concept has emerged from this research that is known as a green schoolyard.

Stephen Pont is the medical director at <a href="https://www.dellchildrens.net/">Dell Children's Texas Center</a> and an assistant professor of Pediatrics at <a href="https://dellmed.utexas.edu/">UT-Austin Dell Medical School</a>.

"Green schoolyards can include outdoor classrooms, native gardens, storm water capture, traditional play equipment, vegetable gardens, trails, trees and more," said Dr. Pont. "And outside of school time, these schoolyards can be open for the surrounding community to use, benefitting everyone."

Green schoolyards offer <a href="https://www.earth.com/news/deportation-fears-american-children/">children</a> a healthy outdoor environment as part of their daily lives. Green schoolyards also provide value to the entire community by promoting improved health and higher rates of community and family engagement. 

Richard Louv is a co-founder of the <a href="http://www.childrenandnature.org/">Children &amp; Nature Network</a>.

"Too many children have no access to quality school grounds. In many neighborhoods, the standard play space is a barren asphalt playground or a concrete slab surrounded by chain link fence--a completely unsuitable environment for children's play,” said Louv.

In collaboration with the Children &amp; Nature Network and the <a href="http://www.nlc.org/">National League of Cities</a>, five cities have implemented green schoolyards as a result of the research. The study authors have documented green schoolyard advantages such as improved academic outcomes, physical activity, and mental health.

"So many physicians and health professionals choose to spend their free time in nature, but we often forget that nature can be a powerful health intervention for our patients, both for the prevention and improvement of many medical conditions," said Dr. Pont. "We should all be champions for kids and families getting more Vitamin N."

The research will be presented September 16th at the <a href="https://www.aap.org/">American Academy of Pediatrics</a> National Conference &amp; Exhibition in Chicago. The concept will be presented as, "Green Schoolyards Support Healthy Bodies, Minds and Communities.”

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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."
