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.

Researchers from the <a href="https://www.uea.ac.uk/">University of East Anglia</a> have revealed a new threat to the ozone layer. Substances which were not previously considered capable of persisting long enough to reach the stratosphere are now being discovered in large atmospheric concentrations.

The Montreal Protocol is an international treaty that was signed in 1987 to begin the process of phasing out the production of chemicals that were destroying the <a href="https://www.earth.com/video/ozone-layer-new-sensor/">ozone layer</a>. According to this new study, however, there are increasing emissions of substances not regulated by the treaty that are threatening the ozone’s recovery.

Lead author David Oram explained that the harmful substances were not believed to be damaging because they were "generally thought to be too short-lived to reach the stratosphere in large quantities.”

Emissions from countries like China can be particularly damaging to the ozone due to the fact that cold-air surges in East Asia can quickly carry air pollution into the tropics. Airborne substances in this region of the world can reach the ozone layer before dissipating and while they are still capable of causing damage.

One of the dangerous chemicals identified by the research team is dichloromethane, a substance with many uses including the production of pharmaceuticals. Although the amount of dichloromethane in the atmosphere decreased in the 1990s and early 2000s, the researchers found that it has become about 60 percent more abundant over the past decade. 

"This was a major surprise to the scientific community and we were keen to discover the cause of this sudden increase," said Oram. "We expected that the new emissions could be coming from the developing world, where industrialization has been increasing rapidly.” 

The team measured air pollution in East Asia in an effort to determine where the increase in dichloromethane was originating from and whether or not it could affect the ozone layer.

"Our estimates suggest that China may be responsible for around 50-60% of current global emissions [of dichloromethane], with other Asian countries, including India, likely to be significant emitters as well," said Oram.

Another ozone-depleting chemical detected in large quantities by the team is dichloroethane, a substance used in making PVC. China is the largest producer of PVC and its production has increased tremendously over the last two decades. The researchers were shocked to find the prevalence of dichloroethane in the atmosphere because it is “highly toxic" and also a “valuable commodity.”

Oram concluded, "We are highlighting a gap in the Montreal Protocol that may need to be addressed in the future, particularly if atmospheric concentrations continue to rise.”

The study is published today in <a href="https://www.atmospheric-chemistry-and-physics.net/">Atmospheric Chemistry and Physics</a>, a journal of the <a href="https://www.egu.eu/">European Geosciences Union</a>.

A dangerous new threat to the ozone layer

Researchers from the University of East Anglia have revealed a...

When we think of underdeveloped or developing countries moving to the next step, it usually comes along with the processes of industrialization and agricultural growth – particularly in the Western world.  However, a new study published in <a href="https://www.ecologyandsociety.org/">Ecology and Society</a> attempts to flip this ideology on its head. 

Ashwin Ravikumar, an environmental social scientists at <a href="https://www.fieldmuseum.org/">The Field Museum</a>, and his colleagues believed that governments have been too quick to dismiss indigenous peoples’ traditional ways of life, and the well being that they create. In many cases, these communities are living a high quality of life through managing their natural resources in a sustainable fashion as a result of traditional hunting, fishing, and small-scale agriculture.

This study details an assets-based approach to conservation. “Rather than fixating on what they lack, we focus on the assets they already have, especially their skills in managing local resources. We create spaces for local communities to think about what choices make the most sense for them,” says Ravikumar.

The researchers worked with rural communities in the Peruvian Amazon, determining that the local populations are able to meet their basic needs through a diverse collection of subsistence activities. These include hunting, fishing, and farming – which over centuries have developed sophisticated natural resource management systems that help protect the <a href="https://www.earth.com/news/illegal-activity-brazilian-amazon/">rainforest ecosystem</a>.

For these indigenous people, “well-being” isn’t defined by owning cars or TVs. “When they talk about well-being, they do talk about money,” says Ravikumar. “But they always include basic needs and natural resources, like having a healthy forest, since forests can be of cultural and spiritual importance.” The indigenous people in the study do rely on money for things such as transportation, but their environment covers most basic needs like food, water, and shelter. 

Through working closely with the people in these communities, the project hopes to lead to the implementation of a conservation plan that complements their existing practices. “We build strong relationships with these communities through a combination of direct work with them on the ground and cataloging how they use traditional knowledge to manage natural resources in an ecosystem,” explains Ravikumar.

Aiding and understanding how these communities sustain themselves will help researchers such as Ravikumar work more efficiently to help them organize politically to gain support from both government and non-government allies, which will help them in the future. In the past, the indigenous people have been exploited by commercial industries as well as their own government. Through this new approach, hopefully their future will be brighter than their past.

A new study from the <a href="https://www.ubc.ca/">University of British Columbia</a> may offer up some hope for a strategy in preventing climate change. The answer? Herbivores. That’s right; researchers believe that plant-eating species may be a key factor in helping certain ecosystems survive global warming.

In their study, the researchers created mini-marine ecosystems on the shore of Ruckle Park on British Columbia’s Salt Spring Island. These ecosystems were built on hard plastic plates, allowing the temperature to be controlled. Limpets, an established herbivore species, were allowed on some plates, while they were made absent on others. 

They were studying life in the intertidal zone, which is the area of the shore between low and high tide. Generally, it contains ecosystems consisting of starfish, mussels, anemones, seaweed, and barnacles. The interesting aspect of these intertidal ecosystems is that they experience huge temperature fluctuations as the tides go in and out – sometimes as much as 20 to 25 degrees Celsius. This means that the species in the intertidal zone must cope with significant temperature variation every day. 

“These creatures are already living at their physiological limits, so a two-degree change – a conservative prediction of the warming expected over the next 80 years or so – can make a big difference,” said Kordas. “When heat waves come through B.C. and the Pacific Northwest, we see mass mortality of numerous intertidal species.”

Surprisingly, the researchers found that certain communities in the intertidal zone could survive even in the warmest summer temperatures – but only if limpets were present in their ecosystem. 

According to Christopher Harley, senior author of the study and a professor of zoology at <a href="https://www.ubc.ca/">UBC</a>, consumers such as <a href="https://www.earth.com/news/sea-otters-dolphins-smartest/">sea otters</a> and starfish like limpets, and these species are very important in maintaining biodiversity in aquatic ecosystems. Losing these species may destabilize ecosystems, so if we’re able to better protect species such as limpets, it may help make ecosystems more resilient.

“We should be thinking of ways to reduce our negative effects on the natural environment and these results show that if we do basic conservation and management, it can make a big difference in terms of how ecosystems will weather climate change,” says Harley.

Who would’ve thought that something so small could be so important to keeping complicated ecosystems intact?

For the past several days, intense wildfires have burned through eight counties in Northern California's wine country, prompting Governor Jerry Brown to declare a state of emergency.

Thus far, the fires have scorched over 170,000 acres of land, and 670 people have been reported missing. California Highway Patrol has already rescued 50 people from mountain tops as the fires began to close in.

Firefighters are working to investigate the cause, but the fires were undoubtedly exacerbated by the <a href="https://www.earth.com/image/santa-ana-wind-event-over-california/">Santa Ana Winds</a>, or “Los Diablos” (devil winds), which create peak fire conditions by quickly moving hot, dry air across California. 

At one time over the weekend, more than 25 different fires blazed across Northern California. More than 44 people were rescued by helicopter, and according to Sonoma County Officials, and more than 100 calls have been made to report possible missing persons. 

As of Wednesday afternoon, the death toll had risen to 21 people, and the fires have destroyed over 1000 homes and business. Cal Fire has also issued new evacuation orders for residents in Calistoga and Santa Rosa.

Though winds have died down, firefighters ares still working to contain the blazes.

Federal funds were immediately allocated to help the state in its recovery efforts and those displaced by fires.

Santa Rosa’s Coffey Park neighborhood was perhaps one of the hardest hit areas as whole street blocks were engulfed.

Even though critical conditions in Northern California are dying down, there is a fear that the fires will move south. 

Thick smoke has also caused dangerously poor air quality in the area, and some residents have been hospitalized for respiratory irritation.

21 dead as wildfires ravage Northern California’s wine country

For the past several days, intense wildfires have burned through...

According to the <a href="http://www.nhc.noaa.gov/">National Hurricane Center</a>, yet another tropical storm has formed in the Atlantic Ocean and is now about 860 miles west-southwest of the Azores Islands on Monday, October 9th. 

The tropical storm, named Ophelia, has yet to pose any threat to land, but marks the 15th storm in an unusually overactive 2017 hurricane season. 

According to <a href="http://www.cnn.com/2017/10/09/us/tropical-storm-ophelia/index.html">CNN</a>, Ophelia is forecasted to become a hurricane by Friday, making it the 10th hurricane this year. 

This <a href="https://www.earth.com/news/a-tropical-storm-in-june-record-heat-in-the-atlantic-could-make-it-happen/" target="_blank" rel="noopener">hurricane season</a> has been catastrophic to parts of the Caribbean, Texas, and Florida, and is now becoming record-breaking, matching only a few seasons in the late 1800s. 

Of the fifteen storms this season, five have been major hurricanes, and three of those were at Category 5. 

According to experts, this season has been especially active due to the perfect conditions falling into place at the right time. 

“What’s making this season so busy is a combination of timing and luck,” Brian McNoldy, a hurricane researcher at the <a href="http://www.rsmas.miami.edu/">University of Miami Rosenstiel School of Marine and Atmospheric Science</a>, told the <a href="http://www.miamiherald.com/news/weather/hurricane/article177950476.html">Miami Herald</a>.

The lack of shear winds, or buffeting and competing winds, that can break up a hurricane’s forceful trajectory, helped create the major wind speeds. 

The warm temperatures in the Gulf of Mexico drove Hurricane Harvey to create record-breaking precipitation. According to McNoldy, the storms avoided the mountainous Caribbean islands that would also have buffered their potency.

Back in May, the<a href="http://www.noaa.gov/"> National Oceanic Atmospheric Administration</a> predicted a more-active-than-normal hurricane season.

“The last time storms intensified into ten consecutive hurricanes was in 1878, 1886 and 1893, although without satellites it's possible some storms in between were missed,” Phil Klotzbach, a<a href="https://www.colostate.edu/"> Colorado State University </a>meteorologist, told the <a href="http://www.miamiherald.com/news/weather/hurricane/article177950476.html">Miami Herald</a>.

Meteorologists and scientists note that the Atlantic hurricane season isn’t over yet, with the month of October still to go.

As one of the most biodiverse regions on the planet, the Brazilian Amazon Rainforest is an invaluable tool for global climate regulation. Despite an increase in protection over the last few decades, illegal activities continue to strip the <a href="https://www.earth.com/news/indigenous-amazon-rainforest-dwellers/">forest</a> of its assets. A new study used law enforcement data from 2010 to 2015 to gain insight into where the illegal use of natural resources is taking place.

4,243 police reports of illegal activities in this protected region were evaluated and mapped. The majority of the registered illegal activities related to the suppression and degradation of vegetation, closely followed by illegal fishing and hunting activities. These incidents generated over 220 million dollars in fines.

The researchers tested several theories on factors that could predict the occurrence of illegal activities in protected areas. These factors included the type of management category, the age of reserve, population density, and accessibility. The team found that population density and accessibility are the strongest predictors of frequent illegal activities in preserved regions. 

Even though Brazil has been a global leader in the use of remote sensing to detect large-scale ecological changes in tropical forests, many disturbances happen "under the canopy" and remain largely undetected and poorly understood. There is not enough funding available to conduct the investigations that are needed on the ground to help prevent these illegal activities.

Study co-author Erico Kauano works for the Brazilian agency that is responsible for the management of federally protected areas.

"Our paper demonstrates that illegal activities within protected areas are still pervasive across the region and that much more work is required to understand their causes and find ways to prevent them," said Kauano. "We hope that our article can highlight the urgency to shift the flow of the resources dedicated to forest conservation, from the well-maintained offices in cities far away from the actual problems to the frontlines where the fate of the tropical forests is going to be decided in the next decades.”

The research is published in the journal <a href="https://peerj.com/">PeerJ</a>.

Methane emissions are not considered to be as harmful to human health as those from carbon dioxide because they do not persist as long in the atmosphere. However, methane is <a href="https://www.edf.org/methane-other-important-greenhouse-gas">84 times</a> as potent as carbon dioxide for approximately 20 years after it is released. Because of its potency, countries are making efforts to reduce methane emissions to help curb global warming.

There is an increasing sense of urgency for countries to accurately calculate their greenhouse gas emissions, particularly due to the Paris Agreement. In one of the largest independent studies of its kind, experts at the <a href="http://www.bristol.ac.uk/">University of Bristol</a> set out to quantify methane emissions from India using observations of methane concentration in the country's atmosphere.

The main purpose for the research was to provide an independent assessment of emissions that could be compared to what has been reported by India to the United Framework Convention on Climate Change (UNFCCC), and to demonstrate the value of this independent check.

The evaluation combined observations from the surface, from an aircraft, and from a satellite that measures methane concentrations globally from space. 

The analysis revealed that that there has been little growth in India's methane emissions over the last few years and that reports from the country's officials have been accurate.

These findings are in sharp contrast to other countries. In China, for example, calculations of greenhouse gas emissions are steadily rising. In the United States, huge discrepancies have been found between the rate of emissions being reported and the estimates of emissions implied from atmospheric observations.

Dr. Anita Ganesan from the University of Bristol's School of Geographical Sciences is the lead author of the study.

"Methane emissions in inventories are highly uncertain due to the complexity of the sources that emit it,” said Dr. Ganesan. “It is not uncommon for countries to report methane emissions with an uncertainty that is as large as the emissions themselves. By using a variety of approaches, we can narrow that uncertainty."

The team will use the techniques developed for this research to examine other tropical regions, whose <a href="https://www.earth.com/news/agriculture-higher-methane-emissions/">methane</a> emissions are poorly understood. The study is published today in <a href="http://www.nature.com/ncomms/">Nature Communications</a>.

Today, EPA administrator Scott Pruitt <a href="https://www.earth.com/news/pruitt-clean-power-plan/">announced the repeal</a> of the Clean Power Plan as a clear nod of support to the flailing coal mining industry. While the landmark legislation aimed to curb greenhouse gases, manage climate change, and improve public health, Pruitt argues it was an overreach by the federal government and devastating to the coal industry. Now, a new study has found that the events that created much of the world’s coal that we use today nearly caused global glaciation millions of years ago.

The study, published in the journal Proceedings of the US Academy of Sciences, documents a scientific first for the researchers who were able to show how the world was very nearly turned into a giant snowball 300 million years ago. 

Coal forms when plant matter turns into peat, layers of soggy, decaying organic plant matter which later hardens into coal. Most of the world’s coal that we use today was created hundreds of millions of years ago during the Carboniferous and the Permian periods. 

During the Carboniferous period, swamp conditions were perfect for the creation of peat, and as many trees died, they sank to the bottom of the swamps. 

All of the carbon dioxide the trees had absorbed was buried in the swamps, and as a result, levels of atmospheric CO2 were significantly lower than normal, causing a major cooling effect that almost pushed the Earth into a “snowball state.”

“This illustrates the enormous dimension of the coal issue,” said Georg Feulner, lead author of the study from the <a href="https://www.pik-potsdam.de/pik-frontpage">Potsdam Institute for Climate Impact Research</a>. “The amount of CO2 stored in Earth's coal reserves was once big enough to push our climate out of balance. When released by burning the coal, the CO2 is again destabilizing the Earth system.” 

Feulner used computer simulations to model what the Earth was like during the Carboniferous and Permian periods. The study also estimated temperatures based on ancient soil samples and fossils and showed drastic fluctuations. 

At one point, CO2 concentrations were below 100 parts per million which is harrowing considering global glaciation occurs below 40 parts per million. 

The findings reveal how much of an impact coal has and had on our planet, causing both major warming and cooling. 

Rapid climate changes were a part of Earth’s early history. But with the amount of fossil fuels burned today, many scientists fear that, unless something is done to keep CO2 concentrations down, the effects will be irreversible. 

“We should definitely keep CO2 levels in the atmosphere below 450 parts per million to keep our climate stable, and ideally much lower than that. Raising the amount of greenhouse gases beyond that limit means pushing ourselves out of the safe operating space of Earth,” said Feulner.

According to a recent study, open ocean wind farms may be able to generate three times more power than wind turbines on land. 

The discovery opens up new opportunities for <a href="https://www.earth.com/news/wind-farms-emissions-great-britain/">wind farms</a> in deep water and the possibility of harvesting wind energy over the ocean.

The study was conducted by Anna Possner and Ken Caldeira from <a href="https://carnegiescience.edu/">The Carnegie Institution for Science</a> and published in the Proceedings of the National Academy of Sciences. 

The researchers have theorized that open ocean wind farms could generate more power because winds are faster over the water than on land.

Faster winds mean that wind turbines could even generate up to five times more power, but the researchers wanted to make sure that the presence of the turbines wouldn’t hinder the wind speeds. 

“Are the winds so fast just because there is nothing out there to slow them down? Will sticking giant wind farms out there just slow down the winds so much that it is no better than over land?” asked Caldeira. 

The team used modeling tools and collected data from large wind farms in Kansas as a point of comparison. 

The results show that open ocean wind farms could potentially generate three times more power than those wind farms on land, especially in the North Atlantic. 

The researchers also found that the wind turbines wouldn’t hinder speeds as they do on land. The Atlantic is home to frequent, low-pressure systems and cyclones due heat escaping the ocean into the atmosphere in the winter. 

These winter systems would work in a turbine’s favor and generate enough electricity to power whole countries. In the summer, that surplus would diminish, and the wind farms might only be able to meet the demands of the United States or Europe. 

The implications of the Possner and Caldeira’s study offer an exciting development for low-cost, clean energy alternatives.

<a href="https://www.epa.gov/">Environmental Protection Agency</a> (EPA) administrator Scott Pruitt announced plans to repeal the Clean Power Plan at an event in Kentucky on Monday. 

Scott Pruitt, the former Attorney General of Oklahoma, is well known for his stance against environmental protection regulations and has <a href="https://www.earth.com/news/scott-pruitt-doubts-global-warming/">denied the existence of climate change</a>. Despite his new job title, Scott Pruitt is a known critic of the EPA and even pursued several legal battles against the agency during President Barack Obama’s presidency.

The Clean Power Plan was instituted by the Obama administration to help combat climate change by limiting man-made greenhouse gas emissions. The legislation aimed to significantly curb air pollution and limit pollutants that cause asthma and disease. 

Pruitt has not been shy about sharing his thoughts on the Clean Power Plan, calling it “unconstitutional” and claiming it hurts the economy. 

“When you think about what that rule meant, it was about picking winners and losers. Regulatory power should not be used by any regulatory body to pick winners and losers,” Pruitt said Monday.

Even though Pruitt claims that clean air is an important concern, he feels that new jobs and economic success, particularly with the coal industry, take precedence.

Thus far, Pruitt has not made any mention of plans to replace the Clean Power Plan or institute new regulations on emissions. His move to repeal without replacing the landmark legislation has drawn fire from environmentalists. 

“A proposal to repeal the Clean Power Plan without any timeline or even a commitment to propose a rule to reduce carbon pollution, isn't a step forward, it's a wholesale retreat from EPA's legal, scientific and moral obligation to address the threats of climate change," former EPA administrator, Gina McCarthy, told <a href="http://www.cnn.com/2017/10/09/politics/environmental-protection-agency-scott-pruitt-clean-power-plan/index.html">CNN</a>.

From July to September most years, a wave of thunderstorms bring rain to the U.S. Southwest and northwestern Mexico. But now the wet weather, known as the North American monsoon, could be drying up.

"Monsoon rains are critical for the southwest U.S. and northwest Mexico, yet the fate of the North American monsoon is quite uncertain," said Dr. Salvatore Pascale, a researcher at the <a href="http://www.noaa.gov/">National Oceanic and Atmospheric Administration</a>, who led a study of the monsoon. "The future of the monsoon will have direct impacts on agriculture, on livelihoods."

Pascale and a team of NOAA researchers used new climate data, including updated information about sea surface temperatures, to study how climate change might be affecting the annual weather pattern. 

By applying more accurate climate models to the North American monsoon, they found that the models reflect the current state of the weather phenomenon. The projections that the more accurate climate model showed could be bad news for the monsoon, the scientists found.

Climate change models that did not correct biases about sea surface temperatures showed that the monsoons were shifting to later in the year. This isn’t the case, the NOAA researchers said.

Instead, once the sea surface temperature corrections were made, the scientists found that the monsoon isn’t shifting. Instead, it’s losing water – dramatically.

The news could throw a wrench in the works for water agencies in the region. 

"Water infrastructure projects take years to a decade to plan and build and can last decades,” study co-author Dr. Sarah Kapnick said in a press release. “They require knowledge of future climate ... to ensure water supply in dry years."

The storms could also shift northward.

The researchers chose to update the climate models for the area because early models predicted the area would dry out, while more recent models contradicted that. The new model falls in line with the earlier projections.

"Models are critical but they are not perfect, and small imperfections can lead to big misunderstandings,” Pascale said. "We are not saying, 'We are sure that this is what will be,' but we wanted to point out some mechanisms which are key, and have to be taken into account in future research on the North American monsoon.”

The study has been published in the journal <a href="http://dx.doi.org/10.1038/nclimate3412">Nature Climate Change</a>. It was funded by the National Oceanic and Atmospheric Administration.

North American monsoon is drying up thanks to climate change

Data from the <a href="http://www.who.int/en/">World Health Organization</a> (WHO) shows that 361,000 children die every year from diarrheal disease that occurs as a result of poor access to clean water, sanitation, and hygiene. In fact, according to WHO, 1 in 4 deaths of children under 5 years old are attributed to unhealthy environments.

What these stats show is that access to <a href="https://www.earth.com/news/worlds-tap-water-contains-plastics/">clean drinking water</a> is of the utmost importance to the lives and overall health of children across the world. Knowing this, researchers are constantly looking to find what factors lead to unhealthy drinking water and how this can be better managed.

A study from the <a href="http://www.uvm.edu/">University of Vermont</a> of 300,000 children in 35 countries recently found that kids whose watersheds have more tree cover are less likely to get diarrheal disease – which is the second leading cause of death for children under five. This study is the first to quantify the connection between watershed quality and the individual health outcomes of children on a global scale.

“Looking at all of these diverse households in all these different countries, we find the healthier your watershed upstream, the less likely your kids are to get this potentially fatal disease,” says Taylor Ricketts of the <a href="http://www.uvm.edu/">University of Vermont</a> (UVM).

The research team believes that a 30 percent increase in upstream tree cover in rural watersheds could have a comparable effect to improved water sanitations, such as the addition of indoor plumbing or toilets.

“We are not saying trees are more important than toilets and indoor plumbing,” says Diego Herrera, lead author of the paper and a former UVM postdoctoral researcher. “But these findings clearly show that forests and other natural systems can complement traditional water sanitation systems, and help compensate for a lack of infrastructure.”

This study shows that protecting trees and watersheds can also double as a public health investment, as well as an investment in protecting our environment. The researchers hope that governments and development agencies will use these findings to improve the health and environment of children around the world.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

Wildlife tunnels save millions of amphibians

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

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



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



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

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."
