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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

Lightning will ignite even more wildfires as the climate heats up

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

A massive iceberg has broken off from Antarctica's Pine Island Glacier. The detached chunk of ice measures 103 square miles, which is over four times the size of Manhattan. There are concerns that this calving event could accelerate the loss of more ice from the glacier, and ultimately break down the barrier that prevents land-based ice from floating off into the ocean.

Pine Island Glacier is one of the largest ice streams on the West Antarctic Ice Sheet. It is melting faster than any other glacier in Antarctica and its rate of ice loss has been speeding up for 40 years. This event marks the second time in two years that a huge iceberg has retreated from Pine Island Glacier. This incident also closely follows one of the largest calving events ever recorded when an iceberg the size of Delaware broke off from Larsen C. 

Although the iceberg will not directly contribute to sea level rise, it will have an indirect impact. These floating ice shelves create barriers that prevent land ice from floating off into the ocean. These barriers are broken down as the ice shelf splits, allowing land ice to glide away and expand the ocean. If Pine Island Glacier completely melted, sea levels would rise by as much as 1.7 feet.

Scientists believe that warming ocean waters are melting the <a href="https://www.earth.com/news/iceberg-larsen-c-antarctica/">icebergs</a> from below, triggering them to detach and float away. There is also evidence that the warming sea is weakening the base of Pine Island Glacier and changing the patterns of ice loss. While icebergs usually break away from the sides, the rift that led to the latest calving formed in the center.

Dr. Stef Lhermitte is a satellite observation specialist from <a href="https://www.tudelft.nl/en/">Delft University of Technology</a> in the Netherlands. He was the first to report the news of the iceberg on Twitter. 

“It’s the fifth large calving event since 2000,” said Dr. Lhermitte. “This one and 2015, they were much further inland than the previous ones. So there has been a retreat of the calving front, specifically between 2011 and 2015.”

Some parts of the world experience a rainy season, like in southeast Asia, while other parts of the world see consistent rain year-round, like in the Pacific northwest. But some places experience more rain than anywhere else in the world. <a href="http://earth.com">Earth.com</a> presents: the Top 10 wettest places on Earth.

Emei Shan, China

Mount Emei is the tallest of the Four Sacred Mountains of Buddhism as located in the Sichuan Province of China. The “Cloud Sea” there, which is named for the clouds visible above and below from the top of the mountain, is responsible for the heavy rainfall, which averages 8,169 mm annually––the most rainfall in China.

Kukui, Hawaii

Pu’u Kukui is the highest peak of Mauna Kahalawa (the West Maui Mountains) and came to be when a crater formed by a volcanic collapse created the I’ao Valley below. With 9,239 mm of rainfall a year, it is the third wettest place in Hawaii. 

Mount Waialeale, Hawaii

This extremely slippery, rain forested mountain is the second highest point on the island of Kaua’i and the second wettest place in Hawaii with 9,763 mm of rainfall a year. Its name can be translated to “overflowing water.” 

Big Bog, Hawaii

The wettest place in Hawaii is on the island of Maui and is a popular tourist destination even though access to the island requires either a helicopter ride or two days of hiking. Annual rainfall averages 10,272 mm.

Debundscha, Africa

This village in the south-western region of the Republic of Cameroon lies at the foot of Mount Cameroon––the highest peak in Africa, and faces the south Atlantic Ocean. The weather there is in stark contrast to the dry weather affecting of most of the continent and rainfall averages 10,299 mm a year. 

San Antonio de Ureca, Equatorial Guinea

This region on Bioko Island is the wettest place on the African continent. During the brief dry season from November to March, tourists flock to see turtles come ashore and lay eggs. Annual rainfall averages 10,450 mm.

Cropp River, New Zealand

This river flows east for 9 km before it joins with the Whitcombe River. Rainfall over the body of water averages 11,516 mm a year.

Tutendo, Comombia

This city in the north western region of Colombia, South America has a population of less than 1,000 people and is the third wettest place on earth with an average rainfall of 11,770 mm a year.

Cherrapunji, India

The town Cherrapunji, also known as Sohra, can be found in the East Khasi Hills district in the Indian state of Meghalaya. Despite being the second wettest place in the world averaging 11,777 mm of rainfall a year, the region faces acute annual water shortages during the dry months of winter. 

Mawsynram, India

This village, found in the same East Khasi Hills district of Meghalaya (15 km from Cherrapunji), is the wettest place on earth. Villagers reportedly use grass to soundproof their domiciles from the deafening sound of pelting rain during the wet seasons. Their annual rainfall averages 11,871 mm.

The Top 10 wettest places in the world

Nitrogen can be a tricky element to deal with for farmers. While it’s a popular and important ingredient in many fertilizers, it can also run off into nearby streams and seep into the groundwater as nitrates, which creates dead zones and algae blooms that kill fish. 

Now, new research has identified nitrate removal hotspots where nitrates from fertilizers are filtered out of the water, usually by a buffer zone with local plant species. 

Molly Welsh, a graduate student from the <a href="http://www.esf.edu/">State University of New York College of Environmental Science and Forestry</a>, led a study that found and analyzed these hotspots. 

"Understanding where nitrate removal is highest can inform management of agricultural streams. This information can help us improve water quality more effectively,” said Welsh. 

The researchers collected data and water samples from four streams in Northwestern Carolina, exhibiting a wide range of nitrate removal close to agricultural activity. 

Welsh then analyzed the water samples and found that the buffer zones next to the streams had the highest success rate of <a href="https://www.earth.com/news/contaminants-found-in-california-public-drinking-water-2/">nitrate</a> removal. Sediments in the waterways, which were also analyzed, were not nearly as efficient at removing nitrates.

Buffer zones are abundant with organic matter, high levels of moisture, and fine-textured soils, which makes them perfect at filtering out harmful contaminants. Nitrate removal appears to highest where there is a lot of native plants and fine sediments. 

Welsh also examined pools created during stream restoration using rocks that spanned across the waterway, which was also not very effective at removing nitrates. 

Welsh suggests that using woody debris would be a better method than rocks to filter nitrates given the success of the buffer zones. 

“Our results show that it may be possible to develop simple models to guide nitrogen management,” said Welsh. 

The new research shows the importance of natural buffer zones to protect ecosystems from harmful nitrate runoff.

It has been theorized that millions of years ago, the Mediterranean Sea experienced a massive drying out after the Strait of Gibraltar closed temporarily, and the Mediterranean Sea was cut off from the Atlantic Ocean. Now, new research may have proven that this drying out also increased seismic activity in the area at the time. This means that shifts in surface temperatures and geological landscape from climate change could cause an uptick in volcanic activity. 

Geologists from the<a href="https://www.unige.ch/en/university/"> University of Geneva</a>, <a href="https://www.univ-orleans.fr/en/international/come-study-university-orleans">University of Orleans,</a> <a href="http://www.upmc.fr/en/">University Pierre and Marie Curie in Paris</a>, and the <a href="http://www.ictja.csic.es/">ICTJA-CSIC Institute in Barcelona</a> studied volcanic data from the time the Strait of Gibraltar was closed, otherwise known as the Messinian salinity crisis.

The presence of crystallized minerals, which form as magma cools on the earth’s surface, indicated that the salinity crisis had triggered more than a 200% increase in volcanic activity.  

Researchers believe that a total of 13 <a href="https://www.earth.com/news/fear-bali-volcano-eruption/">eruptions</a> were caused by the drying out of the Mediterranean. The drastic changes in pressure and depth caused by the salinity crisis had a major impact on magma production and increased volcanic activity. 

“The single logical explanation is the hypothesis that the sea dried out, since this is the only event powerful enough to alter the Earth's pressure and magmatic production over the entire Mediterranean,” said Pietro Sternai a researcher from the University of Geneva’s Science Department. 

As climate change continues to impact the Earth, this research reveals that changing temperatures can even increase seismic activity deep below the Earth’s surface, a possible warning sign of more volcanic eruptions in the future.

Many studies have been done analyzing the effect of noise – specifically human <a href="https://www.earth.com/news/noise-pollution-protected-areas/">noise pollution</a> – on the physiology and behavior of animals in the wild. This noise pollution comes from things such as transportation, construction, and just general proximity to areas with human activity.

Recently, a study has revealed that this same noise pollution can have negative effects on the schooling behavior of fish. Schooling is a collective behavior for some fish species that is integral to helping them avoid predators and exchange information between individuals. 

For the study, 450 individual seabass were tested in shoals of four individuals each at the aquarium in the <a href="http://www.bristol.ac.uk/">University of Bristol</a>. Recorded sounds of pile-driving, which is used in the construction of marine infrastructure like piers and windfarms, were played to small schools of seabass.

Researchers noticed that the fish became less coordinated and cohesive when these sounds were played. These changes in their behavior suggest that exposure to human noise pollution may make them more susceptible to predators, and affects individual fish on a group level.

“This is one of the few studies to explore how pollution from human activity impacts schooling behavior in fish,” says Christos Ioannou from the <a href="http://www.bristol.ac.uk/">University of Bristol</a>. “By using state-of-the-art computer tracking software, we were able to measure and analyze the movement of individual fish and the shoal as a whole in great detail.”

With these results found in the lab, the next step in this research is to determine if the fish experience similar effects under natural conditions. If the findings end up translating to fish in nature, it may be time to rethink how we conduct particularly noisy human activities around marine life.

Researchers from <a href="http://www.columbia.edu/">Columbia University</a> have conducted a groundbreaking study to explore the concept of evaporation as a renewable energy source. Their analysis reveals that lakes and reservoirs in the United States could generate 325 gigawatts of power, which is almost 70 percent of what the country currently produces.

While the testing has been limited to the lab, the studies suggest that evaporation-harvested power could be made on demand, 24 hours a day. This means that it could be much more feasible than utilizing solar or wind energy.

Ozgur Sahin is a biophysicist at Columbia University and the study’s senior author.

"We have the technology to harness energy from wind, water and the sun, but evaporation is just as powerful,” said Sahin. "We can now put a number on its potential."

Sahin and his colleagues have previously shown how energy behind the cycling of water and air can be harnessed. The team developed a machine called Evaporation Engine, which controls humidity with a shutter that opens and closes. This causes bacterial spore contractions which are transferred to a generator that makes electricity. The current study was created to determine just how much power this process could hypothetically produce.

"Evaporation comes with a natural battery," said lead author Ahmet-Hamdi Cavusoglu. "You can make it your main source of power and draw on solar and wind when they're available." 

This type of evaporation technology can also save water. The research team estimates that half of the water lost from lakes and reservoirs to evaporation could be saved during the energy-harvesting process. In their study, the water savings totaled 25 trillion gallons a year, which is around 20 percent of the amount of water Americans consume.

Energy from evaporation could be most advantageous to states with growing populations and hotter, dryer weather.

States which are prone to <a href="https://www.earth.com/video/world-recover-drought/">drought</a> such as California, Nevada and Arizona could benefit the most, where evaporation could pump out more energy while reducing water waste.

The study, which is published in <a href="http://www.nature.com/ncomms/">Nature Communications</a>, is being continued as the 
researchers work to improve the energy efficiency of their spore-studded materials. They hope to eventually experiment outside of the lab to more accurately test their technology’s ability to generate power and limit water loss at the same time.

Researchers took a closer look into the cause of a deadly landslide that devastated Saint-Jude, Quebec, in May 2010. The study, which was based on investigations that directly followed the event, revealed that the landslide was triggered by a disturbance of highly sensitive clay sediment that is 10,000 years old.

The experts found that the solidity of the underlying clay was compromised by natural causes of the Salvail River, which cuts through the base of the landslide site. Both sediment erosion caused by the river and high groundwater pressure beneath the river contributed to the decreased stability of the clay sediment.

The landslide was determined to have happened in two phases, with two major shifts at two different elevations causing the event. 

Dr. Ariane Locat is the lead author of the report and a professor in the Department of Civil Engineering and Water Engineering at <a href="https://www.ulaval.ca/">Université Laval</a>. She explained that, "Such features have never been clearly identified before in spreads in sensitive clays.”

The research team reconstructed the landslide through field and laboratory tests using what they had learned about the properties of the soil and the shape and positions of the clay debris. They classified it a "large" and "complex spread," a typical landslide type occurring in sensitive clays. The landslide had a width of 275 meters and a volume of debris of ~520,000 m3, which is the equivalent of the volume of more than 200 Olympic-sized swimming pools. 

"Scientific knowledge on spreads in sensitive clays is limited,” said Dr. Locat.  “Investigations of case studies, like the one presented in this study of the Saint-Jude landslide, give us new information and insights on characteristics of spreads and on conditions in which they occur.” 

90 percent of Quebec's population resides among these “quick clays,” which are leftovers from the Champlain Sea. Quebec is more vulnerable to landslides brought on by the disturbance of this sensitive clay sediment than any other <a href="https://www.earth.com/news/global-risk-natural-disasters-doubled/">natural disaster</a>.

"These studies are essential to the development of tools allowing for better identification of zones potentially exposed to spreads and to protect the population from this natural hazard,” added Dr. Locat.

The study is published today in the <a href="http://www.nrcresearchpress.com/journal/cgj">Canadian Geotechnical Journal</a>.

Tens of thousands of Indonesians have been evacuated as fears grow that Bali’s Mount Agung is on the verge of eruption. Due to increased seismic activity, a 7.5-mile exclusion zone has been set up around the volcano as 50,000 residents are being moved to temporary shelters.

The <a href="http://www.wovo.org/1601_1607.html">Centre for Volcanology and Geological Hazard Mitigation</a> (PVMBG) has raised the volcano alert to its highest level. The latest analysis from the PVMBG indicates that the seismic energy of Mount Agung “continues to increase and has the power to erupt.” The report also urges communities to continue to raise awareness and get prepared.

Hundreds of tremors are now being recorded from within Mount Agung daily, indicating that the magma is rising closer to the surface of the volcano. According to Australia's <a href="http://www.news.com.au/">news.com.au</a>, a total of 198 tremors were recorded between Friday at midnight and noon on Saturday. The news outlet reports that the rumblings began to slack off Saturday morning but picked up speed again by Saturday afternoon.

The head of the PVMBG said that very small tremors have been occurring ever since the eruption of Mount Agung in 1963, which destroyed villages and killed over 1100 people. According to the <a href="http://www.bmkg.go.id/?lang=EN">Department of Meteorology, Climate and Geophysics</a>, there has been a “tremendous increase” in seismic activity in the area.

<a href="https://www.earth.com/news/mount-sinabung-indonesia-erupts-months-activity/">Indonesia</a> is made up of over 17,000 volcanic islands that straddle the Pacific “Ring of Fire,” the world's largest earthquake belt with fault lines stretching 25,000 miles. The Ring of Fire is also home to more than half of the world's volcanoes, both dormant and active. Indonesia itself  has over 120 active volcanoes, more than any other country. 

The <a href="http://balitourismboard.or.id/page/crisis-center/no-volcanic-ash-detected.html">Bali Tourism Board</a> is urging residents to plan on staying indoors in the event of ashfall or to prepare by stocking up on face masks. Ferry services and flights into Bali have not been cancelled at this point, but travel warnings have been issued.

Although current President of the United States Donald Trump has denied the existence of climate change, many of his predecessors enacted much more environmentally friendly policies. Here’s a list of the Top 10 most environmentally friendly U.S. Presidents.

Theodore Roosevelt

When Theodore Roosevelt entered the White House in 1901, he made environmental affairs a top priority. He signed into law the Antiquities Act, giving presidents the authority to proclaim federal lands as national monuments. During his time in office, Teddy Roosevelt created 50 wildlife refuges and 5 national parks. He also set aside 150 million acres of timberland and helped develop the the U.S. Forest Service.

Richard Nixon

Richard Nixon was responsible for the National Environmental Policy Act, the first law that provided a legislative structure for protecting the environment. The Environmental Protection Agency (EPA) was also developed under his administration to enforce such laws. Nixon's Clean Air Act required the EPA to create and enforce air pollution regulations. 

Jimmy Carter

In his first year as president, Jimmy Carter launched the Department of Energy, with a mission “to ensure America's security and prosperity by addressing its energy, environmental and nuclear challenges through transformative science and technology solutions.” Carter also established the Soil and Water Conservation Act and the Endangered American Wilderness Act. 

Barack Obama

President Obama stood by his belief that “no challenge poses a greater threat to our children, our planet and future generations than climate change, and that no other country on Earth is better equipped to lead the world towards a solution." Obama introduced the Clean Power Plan, which paved the way for the Paris climate agreement of 2015. Obama also used the Antiquities Act more than any other president, creating over 20 national monuments.

Lyndon B. Johnson

During his second term in office, President Johnson was focused on his “Great Society” plan, which led to the creation of  the Wilderness Act of 1964 and the Land and Water Conservation Act of 1965. Johnson's administration was also responsible for the Endangered Species Preservation Act of 1966 and the National Trails System Act of 1968.

Franklin D. Roosevelt

The work of FDR resulted in countless nature beautification programs. FDR created the Civilian Conservation Corps, which provided jobs for millions of unemployed men. Their work produced billions of trees and constructed over 800 parks across the country, many of which became state parks. 

Bill Clinton

While some of the events of his years may suggest otherwise, Clinton managed to make a lot of progress in the direction of a healthier planet. He oversaw the creation of 17 national monuments and expanded four existing monuments, preserving over 4.6 million acres - the most of any administration. He also increased clean energy research and development funding by 50 percent, to more than $3 billion.

Woodrow Wilson

President Wilson may not have had as many green accomplishments as other presidents that make this list, but the creation of the National Park Service in 1916 was one of the greatest. It provided the funding and manpower to help reinforce the efforts of Teddy Roosevelt. 

Abraham Lincoln

Lincoln established the U.S. Department of Agriculture to provide support for American farmers in 1862. He passed the Morrill Land-Grant Colleges Act the same year to provide funding for agricultural colleges. His Yosemite Grant protected what is known today as Yosemite National Park.

Thomas Jefferson

Jefferson was well ahead of the time in his vision to protect the environment. He wrote in 1806, "We must use a good deal of economy in our wood, never cutting down new, where we can make the old do."

Low soil fertility can cause all kinds of trouble, not least of which is protein malnutrition, which can in turn, reduce crop yields. But researchers have now found that legumes can help boost soil fertility, especially for smaller farms.

Next month, a meeting hosted by the <a href="https://www.agronomy.org/">American Society of Agronomy</a>, the <a href="https://www.crops.org/">Crop Science Society of America</a>, and the <a href="https://www.soils.org/">Soil Science Society of America</a> will address this issue and present alternatives to improving legume farming from seed to soil to yield. 

“Building strength in legume-based agricultural systems can help address both of these dire problems," said Kerry Clark, a researcher at the <a href="http://missouri.edu/">University of Missouri</a>. 

Improving soil fertility will create a ripple effect, notes Clark, and small farms will have better access to “economic and nutritional alternatives" to the crops used now. 

The key is educating farmers about legumes, working with the public to increase awareness about the issues with soil depletion and infertility, and providing hands-on training to legume breeders. 

Clark will be one of the speakers at the symposium, presenting work done by the Soybean Innovation Lab, which is working to research breeding in tropical legumes among many other projects.

An unprecedented study of plants conserved outside of their natural habitats has found that 30 percent of all identified plant species are contained in botanic gardens across the globe. 41 percent of all plant species classified as “threatened” are included in the gardens.

The study by researchers from the <a href="https://www.cam.ac.uk/">University of Cambridge</a> also revealed that almost two-thirds of plant “genera" are housed in the world's network of botanic gardens, and over 90 percent of plant families are represented.

On the other hand, the researchers found a notable imbalance between gardens in temperate and tropical regions. They discovered that a great majority of all plants species grown “ex-situ,” or outside of their natural environments, are located in the Northern Hemisphere.

Because of this, 60 percent of temperate plant species were represented in the botanic gardens compared to only 25 percent of tropical species. Most plant species are tropical, so they would be expected to be conserved in higher numbers.

The research team analyzed datasets compiled by <a href="https://www.bgci.org/">Botanic Gardens Conservation International</a> (BGCI). They compared the 350,699 known plant species with the species records of 1,116 botanic gardens. Despite housing almost half of all threatened species, the botanic gardens had only around 10 percent of overall storage capacity dedicated to these imperiled plants. 

The researchers say that botanic gardens are of "critical importance to plant conservation,” and global efforts are needed to protect more species of plants that are at risk of extinction, especially those from tropical climates.

Dr. Samuel Brockington, the study's senior author, is a researcher of Plant Sciences and a curator of the botanic garden at the University of Cambridge. 

"The global network of botanic gardens is our best hope for saving some of the world's most endangered plants," said Dr. Brockington. "Currently, an estimated one fifth of plant diversity is under threat, yet there is no technical reason why any plant species should become extinct. Botanic gardens protect an astonishing amount of plant diversity in cultivation, but we need to respond directly to the extinction crisis.”

The study is published today in the journal <a href="http://www.nature.com/nplants/">Nature Plants</a>.

Nearly three decades of conservation efforts to protect giant pandas has led to recent increases in their populations. A study by Chinese and U.S. scientists, however, has found that giant panda habitats cover less area and are more fragmented than when pandas were first listed as an endangered species.

"The International Union for Conservation of Nature (IUCN) has recently changed the status of the giant panda from 'endangered' to the less threatened 'vulnerable,' " said researcher Stuart L. Pimm of <a href="https://www.duke.edu/">Duke University</a>. "This was based on the increasing numbers, which are a very encouraging sign, of course."

"But what my colleagues and I wanted to know was how the panda's habitat has changed over the last four decades, because the extent and connectivity of a species' habitat is also a major factor in determining its risk of extinction," said Pimm.

The researchers used geospatial technologies and remote sensing data to map changes such as new roads that divide <a href="https://www.earth.com/news/panda-bears-fur-communication-camouflage/">panda</a> habitats across the panda’s entire range. The scientists focused on geographical changes that occurred from 1976 to 2013.

The team was led by Zhuyan Ouyang and Weihua Xu of the Research Center for Eco-Environmental Sciences at the <a href="http://english.cas.cn/">Chinese Academy of Sciences</a>.

"We found complex changes," Xu said. "Habitat decreased nearly 5 percent from 1976 to 2001, but has increased since. However, the average size of the habitat patches decreased by 23 percent from 1976 to 2001. It has increased only slightly since."

Study co-author Jianguo Liu of <a href="https://msu.edu/">Michigan State University</a> pointed out that some of the changes revealed in the study are encouraging.

"Banning commercial logging in natural forests, establishing nature reserves and helping residents in the reserve change behaviors that damaged habitat has been beneficial," said Liu. "But conservation is a dynamic process with humans and nature in a constant push and pull to survive and thrive, so new solutions always are in demand."

Other changes observed by the researchers are advantageous to humans yet hinder progress in conservation efforts.

"The most obvious changes in this region since Professor Liu and his colleague Professor Zhiyun Ouyang first visited it together in 2001 have been the increase and improvement in roads and other infrastructure," said Pimm. "These have been the major factor in fragmenting the habitat. There was nearly three times the density of roads in 2013 than in 1976."

"We suggest several solutions," said Ouyang. "One of the most important will be to establish protected corridors through which pandas can move to prevent their isolation into small and unsustainable populations."

The study is published in the journal <a href="http://www.nature.com/natecolevol/">Nature Ecology and Evolution</a>.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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