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.

Texas Is Also Suffering From Increased Threatening Wildfires. Larger, more threatening wildfires are occurring at greater rates as Texas faces lingering drought, consistent development - driven by millions of new residents and the spread of outlying suburbs - and changes in how the state's land is used.
Texas had 157,000 wildfires over a nine-year period ending in 2014, said Mark Stanford, fire chief of the Texas A&amp;M Forest Service. Nearly 80 percent of those fires raged within 2 miles of a community, he said.
"When I started, that was unheard of," Stanford said. "Wildfires were a rural problem and not really a threat to communities."
Now those threats have turned perennial amid drought and development in areas that had been mostly rural. The latest danger erupted this month when the Hidden Pines fire in Central Texas' Bastrop County burned nearly 5,000 acres and destroyed 77 buildings, including 64 homes, according to the forest service. Flames threatened another 95 homes.
The forest service responded to just one wildfire of at least 5,000 acres from 1985 to 2000, but in the last 15 years there have been fires of that size nearly every year. There were 27 fires at least that size in 2008 and 76 in 2011.
Four years ago, the Bastrop County Complex wildfire that destroyed more than 1,650 homes proved to be the most destructive in Texas history.
With the state population steadily growing - from about 21 million in 2000 to 27 million now - Stanford said a concern for public safety officials is people moving beyond the suburbs and into areas where brush, trees and other vegetation can fuel flames.
"I'm not slamming people who want their piece of Texas heaven," he said, adding that "people see the losses that have occurred and want to do something about it."
He said state programs such as community wildfire protection plans must be encouraged to minimize fire threats.
Texas' landscape has a much different appearance today compared to past decades, said Tom "Andy" Vestal, emergency services coordinator for Texas A&amp;M AgriLife Extension Service. He said it's one prone to inflating fires rather than containing them.
In Texas Hill Country, for example, much of the land used to be reserved for cattle and other animals that munched on the vegetation, Vestal said.
"Land use over the past two decades has changed enormously," he said. "There are fewer grazing animals out in those rural environments."
With the addition of housing and other developments, the vegetation is left to grow and be more vulnerable to fires.Texas Is Also Suffering From Increased Threatening Wildfires
Stanford said the state's intensive agricultural practices once did a lot to prevent large wildfires. But agriculture as an economic and land-management practice has faded in parts of Texas.
"The public generally likes to look at nature as this static picture that never changes," Stanford said. "And it's actually very dynamic."
Lynne Tolmachoff, spokeswoman for the <a href="http://www.earth.com/image/august-complex-fire-has-become-the-largest-in-californias-history/">California</a> Department of Forestry and Fire Protection, said California is experiencing the same trends as Texas: more people in rural areas building among the trees, little rain and soaring temperatures that can intensify fires.
This year alone, 8,000 wildfires have spread across 825,000 acres in California. "The wildfire season here won't let up," Tolmachoff said.
She said wildfire season traditionally ran from around June to October, but has more recently expanded by more than two months.
Texas, California and other states need greater promotion of prescribed burns, said Robin Verble, an assistant professor of fire ecology at Texas Tech University. She said Texas has taken a progressive approach in allowing landowners greater latitude in using controlled burns to minimize vegetation.
"More prescribed fire means less wildfire," she said.

NASA's TIMED Mission Finds Unexpected Trends In Carbon Data. NASA’s TIMED mission, short for Thermosphere, Ionosphere, Mesosphere Energetics and Dynamics, has confirmed a surprisingly fast carbon dioxide increase in Earth’s upper atmosphere, raising questions about how different layers of the atmosphere are interconnected. Even more curious—though climate models predict carbon dioxide should increase more or less equally across the globe, in its 14 years of data collection, TIMED observed a much faster increase of carbon dioxide above the <a href="http://www.earth.com/news/new-ice-age-northern-hemisphere/">Northern Hemisphere.</a>

Understanding the way carbon dioxide moves throughout the atmosphere is key, both for making accurate climate models and for planning spacecraft flight paths. Though carbon dioxide raises temperatures near Earth’s surface, it actually causes cooling in the upper atmosphere, reducing air density in these outermost reaches of the atmosphere and impacting spacecraft orbits.

This study, published in Geophysical Research Letters on Sept. 5, 2015, uses 14 years of data from a radiometer on board the TIMED satellite, the first satellite capable of making long-term measurements of carbon dioxide concentration in the upper atmosphere when it launched in 2001.

“Before TIMED, the only measurements of carbon dioxide in the upper atmosphere were direct measurements from sounding rocket research flights and short-lived spaceborne sensors,” said Jia Yue, a researcher at Hampton University in Hampton, Virginia, and lead author on the study. “But it’s impossible to study long-term trends from snapshots.”

Carbon dioxide is being poured into the atmosphere by human activities, like the burning of fossil fuels and deforestation. A 5 percent per decade increase in carbon dioxide concentration in the lower atmosphere is confirmed by some 56 years of measurements at Earth’s surface. But in the upper atmosphere, the increase in carbon dioxide concentration was observed reaching rates of 12 percent per decade around 70 miles above the surface.NASA's TIMED Mission Finds Unexpected Trends In Carbon Data

Furthermore, they discovered that the carbon dioxide in these upper layers, long thought to follow the same patterns across the globe, is increasing faster over the Northern Hemisphere. Though the Northern Hemisphere produces much more carbon dioxide because of its greater land area and population, scientists expect the difference to become negligible at such great heights due to diffusion and mixing.

“It seems clear that we don’t quite understand the relationship between the lower atmosphere and the upper atmosphere,” said Diego Janches, TIMED project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We tend to separate them into different fields—lower atmosphere is Earth science, upper atmosphere is heliophysics—but we need to understand the atmosphere as a complete system.”

This study’s result also confirms a second set of data from a satellite with capabilities similar to TIMED—the Canadian Space Agency’s SciSat-1, launched in 2003. An analysis of eight years of SciSat-1 data gave the first indication of the accelerated increase of carbon dioxide in the upper atmosphere.

“The support between observations by TIMED and SciSat-1—which use different remote sensing techniques to detect carbon dioxide—confirms that the quick increase is a real, physical trend, and not an artifact of any instrument or data,” said Yue.

Identifying these unexpected trends was only possible because of the long lifespan of TIMED’s radiometer, which is still operating well. The TIMED satellite, originally slated for a two-year mission ending in 2003, has been granted six extended missions. TIMED’s current mission is set to end in 2017, but scientists are hopeful that data collection will continue.

“Long-term studies are necessary to understand trends like this,” said Janches. “TIMED has lasted so long that it’s like a completely different mission—we can do entirely new science when we have long periods of continuous observation.”

NASA Goddard manages the TIMED mission for the Heliophysics Division within the Science Mission Directorate at NASA Headquarters in Washington. The Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland, built the spacecraft for NASA.

Lingering Drought Heightens Worries For California Salmon Extinction. Another deadly summer of drought has heightened fears of extinction in the wild for an iconic California salmon, federal officials said Wednesday.
Officials with the National Marine Fisheries Service said preliminary counts indicate that hot, shallow waters caused by the drought killed most of this year's juvenile winter-run Chinook before they made it out to the Pacific Ocean. Lingering Drought Heightens Worries For California Salmon Extinction
It "doesn't look very good," said Garwin Yip, a federal fisheries spokesman.
If a final count this winter confirms the bad news, it would mean a second straight summer in which 5 percent or less of the young fish survived <a href="https://www.earth.com/image/tule-fog-across-californias-central-valley/">California's</a> drought.
Since the fish spawn on a three-year cycle, the die-off would make management of next year's water critical for the <a href="https://www.bing.com/search?q=salmon&amp;cvid=e51aac30dfaf497ba16f8cbd38ad6a23&amp;FORM=ANAB01&amp;PC=HCTS">salmon's</a> survival in the wild.
The development suggests failure for a second year in a row for federal efforts to manage water flows from Lake Shasta, a main reservoir in the state's water system, to keep salmon and other species alive.
"Droughts are always hard on salmon, but water management decisions made it worse this year," said John McManus, executive director of the Golden Gate Salmon Association.
The juvenile salmon depend on water temperatures in the mid-50s, and were unable to survive in the warmer temperatures produced by shallower than usual water.
Chinook salmon are a mainstay of the state's commercial fishing industry. California's fishing industry and environmental groups are vying with the state's farmers for diminishing water supplies in the driest four years on record.

Study Examines How Indigenous People Alter The Amazon Rainforest. Before Europeans arrived, indigenous peoples altered the Amazon rainforest -- but primarily along major rivers.

Their effects were almost imperceptible in rainforest areas more than a day's walk from a river, according to new research published in the Journal of Biogeography.

Lead author Mark Bush, a biologist at the Florida Institute of Technology, says "no one doubts the importance of human actions along major waterways, but whether humans had a greater effect on the ecosystem than any other large creature has yet to be established in much of Amazonia."

Past human influence

Amazonia supported sophisticated cultures before Europeans' arrival, but Bush and an international team of scientists argue that a recent emphasis by researchers on Amazonia as a manufactured landscape overstates the facts.

[caption id="attachment_2385801" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/10/29084342/amazon-watershed_1big_NSF-copy.jpg"><img class="size-thumbnail wp-image-2385801" src="http://cff1.greenatom.net/uploads/2015/10/29084342/amazon-watershed_1big_NSF-copy-150x150.jpg" alt="The Amazon River watershed covers a vast area; research took place in various Amazonian countries." width="150" height="150" /></a> The Amazon River watershed covers a vast area; research took place in various Amazonian countries.[/caption]

Bush and his collaborators "have reversed a decades-long trend of finding an ever-increasing extent and ecological effects of human settlement in pre-Columbian Amazonia," says George Malanson, program director in the National Science Foundation (NSF)'s Division of Environmental Biology, which funded the research.

Malanson says this review of paleoecological data aims "to strengthen a moderate view of Amazonia that was neither pristine nor completely settled."

Amazonia, nearly the size of the continental United States, is a vast landscape. "Extrapolations about human effects from a few archaeological sites, mainly located along watercourses, must be tempered in the face of more wide-ranging data," says Dolores Piperno of the Smithsonian <a href="http://www.earth.com/news/tropical-birds-handle-heat-stress-much-better-than-expected/">Tropical</a> Research Institute, a co-author of the paper.

Insights relevant to today

The paper's findings are relevant to modern society and conservation, its authors believe.

If forests were heavily modified prior to European arrival--as suggested by some recent research--then, Bush says, "they have regrown in just over one tree generation to support their incredible biodiversity." Such rapid recovery could be used to justify logging forests aggressively because they would regrow, he says.Study Examines How Indigenous People Alter The Amazon Rainforest

If, on the other hand, humans had limited influence on forests, the woodlands might not regrow as readily after major disturbances, and logging could lead to long-term degradation.

These questions are important as policymakers decide whether to enforce or relax protections on areas already designated as parks, such as the Yasuni of Ecuador, according to Bush.

The researchers conclude that pre-European land use by the native peoples in Amazonia varied widely in space and time, but that vast areas of the Amazon were hardly affected by human activity.

The study was also supported by Brazil's National Council for Scientific and Technological Development; Brazil's Coordination for the Improvement of Higher Education Personnel; the Smithsonian Tropical Research Institute; and the National Museum of Natural History.

China Displaced by Drought

China Fights Drought By Moving People Out Of The Area. Village elder Yang Zhenjun isn't ready to move out from the valley where his people have herded sheep and tended crops for generations amid arid, drought-prone mountains of <a href="http://www.earth.com/image/historic-flooding-has-killed-hundreds-across-china/">China's</a> northwest. Still, he acknowledges that life as he has known it is all but over.

The community's 60 families have dwindled down to 11 in recent years. Others have left this area, which is almost completely dependent on often-scarce rainfall, and have headed north to plains with better infrastructure and more accessible water.

"The village has completely died," says Yang Zhenjun, a fifth-generation resident of Dacha village in Ningxia province's Xiji County. Still, he is not eager to move. "I was born in this village. I grew up in this village. Everyone struggles with these same feelings."

Most former residents of Dacha have moved under a government plan to relocate 350,000 people to lift them out of grinding poverty which, for their region, has been worsened by an increase in average temperatures of 2.2 degrees Celsius (4 degrees Fahrenheit) over the past half-century that leaves the land more parched.

The U.N. refugee agency says that people being displaced because of climate-related reasons are a growing global problem. It's pushing for greater awareness of their plight during a climate change conference in Paris opening Nov. 30. The UNHCR says long-term planning can help minimize such displacement in the future.

Many of Dacha's houses are empty and overgrown with plants and trees; walls and roofs have crumbled. As people leave, schools and other facilities in villages like <a href="https://www.bing.com/search?q=dacha&amp;cvid=1ab3bf190b97438094577301f9a29ee3&amp;FORM=ANAB01&amp;PC=HCTS">Dacha</a> are forced to shutter, making life tougher for those left behind.

On the other hand, some of the parched land can recover now that fewer people are using its scarce water.

"Resettlement and climate change are becoming more closely entwined," said Sarah Rogers, an Australian geographer who has studied the effects of climate change on China, adding that the Chinese government has identified resettlement as a way to adapt.

There are about 60 million people worldwide living in what the UNHCR terms "climate change hotspots," and China is one of the worst affected, agency spokesman Andreas Needham said in Geneva.

"UNHCR is calling for explicit recognition" of people displaced by climate change at the Paris meeting "to enable states to prevent further displacement in the future," Needham said. The agency wants to push for individual states to address the issue of displacement in climate change policies, in hopes that planning will help reduce both internal and cross-border displacement.

The UNHCR says an average of 26.4 million people have been displaced by natural disasters every year since 2008. Of the 19.3 million thought to be displaced last year, more than 85 percent were in Asia, including 5 million in the Philippines and 3 million each in China and India. China Fights Drought By Moving People Out Of The Area

Many who have moved in Ningxia are for the most part content with the result.

Hai Yanhu, 71, who moved in July 2012 from Panwan village in Xiji County to a resettlement project in Pingluo County in the north, said he is happy to now have running water and a shower. He barely thinks anymore of his old village, where going long distances to fetch water was a daily task.

"We would have to go down into the valley, and carry the water with a pail on our backs. We would go every day, but if there was something special happening at home then we would have to go four or five times a day," Hai said.

Not all the moves were voluntary. Wang Ziyi, 52, said he moved to Pingluo in December 2014 from Huoshizhai in Xiji County because the government claimed the village's land to plant forests to make a tourist site.

Some families tried to live in tents on the outskirts of the old community, Wang said. "But it's cold. If you tried to put up a house the government wouldn't let you build it, so there was no choice but to leave."

Wang said he misses his old town but that the "economy here is better than the economy in the mountains of Xiji. It's more convenient. Here, it's a bit easier to find manual labor jobs."

The government is proud of the relocations. Zou Yuzhong, deputy director of Ningxia Poverty Reduction Bureau, says the government is moving people out of "inhospitable" climates to "help put them on the path to success."

He dismissed any claims that some are unhappy about leaving their ancestral homes.

"They are incredibly happy and absolutely are in favor of the government implementing these livelihood projects," he says.

Some migrants, however, struggle to adapt, said Wang Yuxiao, head of the Yinchuan Green Sustainability Development Centre, a nongovernmental agency.

"There are many old people who do not want to leave their old homes," Wang said. "Another problem the migrants are facing is the problem of finding work once they've moved to their new homes."

Ma Bingfu, 52, who moved to Pingluo from Taobao Village in Xiji County in October 2011, said the young adjust better than older people.

"This area that we're living in now? There's water and the roads are good, and young people are fine here. But old people don't like it. We can't find work. We have no land to grow on and we can't find work."

"Lots of old people want to go back," he said. "In our old villages we had land we could work. Here we have nothing."

The community's 60 families have dwindled down to 11 in recent years. Others have left this area, which is almost completely dependent on often-scarce rainfall, and have headed north to plains with better infrastructure and more accessible water.

"The village has completely died," says Yang Zhenjun, a fifth-generation resident of Dacha village in Ningxia province's Xiji County. Still, he is not eager to move. "I was born in this village. I grew up in this village. Everyone struggles with these same feelings." China Fights Drought By Moving People Out Of The Area

Most former residents of Dacha have moved under a government plan to relocate 350,000 people to lift them out of grinding poverty which, for their region, has been worsened by an increase in average temperatures of 2.2 degrees Celsius (4 degrees Fahrenheit) over the past half-century that leaves the land more parched.

The U.N. refugee agency says that people being displaced because of climate-related reasons are a growing global problem. It's pushing for greater awareness of their plight during a climate change conference in Paris opening Nov. 30. The UNHCR says long-term planning can help minimize such displacement in the future.

Many of Dacha's houses are empty and overgrown with plants and trees; walls and roofs have crumbled. As people leave, schools and other facilities in villages like Dacha are forced to shutter, making life tougher for those left behind.

On the other hand, some of the parched land can recover now that fewer people are using its scarce water.

"Resettlement and climate change are becoming more closely entwined," said Sarah Rogers, an Australian geographer who has studied the effects of climate change on China, adding that the Chinese government has identified resettlement as a way to adapt.

There are about 60 million people worldwide living in what the UNHCR terms "climate change hotspots," and China is one of the worst affected, agency spokesman Andreas Needham said in Geneva.

"UNHCR is calling for explicit recognition" of people displaced by climate change at the Paris meeting "to enable states to prevent further displacement in the future," Needham said. The agency wants to push for individual states to address the issue of displacement in climate change policies, in hopes that planning will help reduce both internal and cross-border displacement.

The UNHCR says an average of 26.4 million people have been displaced by natural disasters every year since 2008. Of the 19.3 million thought to be displaced last year, more than 85 percent were in Asia, including 5 million in the Philippines and 3 million each in China and India.

Hai Yanhu, 71, who moved in July 2012 from Panwan village in Xiji County to a resettlement project in Pingluo County in the north, said he is happy to now have running water and a shower. He barely thinks anymore of his old village, where going long distances to fetch water was a daily task.

"We would have to go down into the valley, and carry the water with a pail on our backs. We would go every day, but if there was something special happening at home then we would have to go four or five times a day," Hai said.

Not all the moves were voluntary. Wang Ziyi, 52, said he moved to Pingluo in December 2014 from Huoshizhai in Xiji County because the government claimed the village's land to plant <a href="https://www.bing.com/search?q=forests&amp;cvid=25c2669767734de58624f592179fbf80&amp;FORM=ANAB01&amp;PC=HCTS">forests</a> to make a tourist site.

Some families tried to live in tents on the outskirts of the old community, Wang said. "But it's cold. If you tried to put up a house the government wouldn't let you build it, so there was no choice but to leave."

Wang said he misses his old town but that the "economy here is better than the economy in the mountains of Xiji. It's more convenient. Here, it's a bit easier to find manual labor jobs."

The government is proud of the relocations. Zou Yuzhong, deputy director of Ningxia Poverty Reduction Bureau, says the government is moving people out of "inhospitable" climates to "help put them on the path to success."

He dismissed any claims that some are unhappy about leaving their ancestral homes.

"They are incredibly happy and absolutely are in favor of the government implementing these livelihood projects," he says.

Some migrants, however, struggle to adapt, said Wang Yuxiao, head of the Yinchuan Green Sustainability Development Centre, a nongovernmental agency.

"There are many old people who do not want to leave their old homes," Wang said. "Another problem the migrants are facing is the problem of finding work once they've moved to their new homes."

Ma Bingfu, 52, who moved to Pingluo from Taobao Village in Xiji County in October 2011, said the young adjust better than older people.

"This area that we're living in now? There's water and the roads are good, and young people are fine here. But old people don't like it. We can't find work. We have no land to grow on and we can't find work."

"Lots of old people want to go back," he said. "In our old villages we had land we could work. Here we have nothing."

Arctic OffShore Drilling

Shell Loses $7.4 Billion After Pulling Oil Rigs From The Arctic. Royal Dutch Shell reported a third quarter loss of $7.4 billion Thursday as it re-organized and cancelled projects, including drilling in Alaska, to cope with the plunge in oil prices.
The net loss compares with a profit of $4.5 billion in the same period last year. Shell reported $7.9 billion in charges, including $2.6 billion for Alaska and $2 billion related to the decision to cancel the Carmon Creek project in Alberta, <a href="http://www.earth.com/image/the-fall-rhapsody-in-ottawa/">Canada.</a>
Excluding one-time items and fluctuations in the value of inventories, the company said profit dropped to $1.8 billion, from $5.8 billion a year earlier, reflecting the plunge in oil prices.Shell Loses $7.4 Billion After Pulling Oil Rigs From The Arctic.
"Shell's integrated business and our performance drive are helping to mitigate the impact of low oil prices on the bottom line in what is a difficult <a href="https://www.bing.com/search?q=enviorment&amp;cvid=319258dbcb644718b586066e7c29e4d0&amp;FORM=ANAB01&amp;PC=HCTS">environment</a> for the industry today," CEO Ben van Beurden said.
Energy companies are struggling to adjust to an age of lower prices after oil dropped to a six-year low in August. Brent crude, the benchmark for North Sea oil, averaged $50.26 a barrel in the third quarter, down 51 percent from a year earlier.
The drop is forcing companies to reconsider the economics of projects.
Shell said it decided to discontinue work on the Carmon Creek thermal oil sands project because it "does not rank in its portfolio at this time."
In Alaska, Shell had intended to access what the U.S. Geological survey estimated to be some 26 billion barrels of conventionally recoverable oil under Arctic waters. But the company's first drilling produced only minor amounts of oil and gas.
"This, combined with the current economic and regulatory environment, has led Shell to cease further exploration activity offshore Alaska for the foreseeable future," the company said.
At the same time, environmental activists had the company in its sights, pledging to thwart the company in the arena of public opinion. Protesters argued that industrial activity would hurt fragile ecosystems and marine mammals. They insisted that the icy Arctic waters could not be cleaned in the event of a spill.
Analysts believe the company took the worst of the hit in Thursday's results.
"I think the bulk of the assets has been written off," Fadel Gheit, a managing director and senior analyst at Oppenheimer &amp; Co. Inc., said in an email.
Shell said it would still pay a dividend of 47 cents a share on third quarter earnings.

Study: Most Vulnerable Countries Know Least About Climate Change. Collaborations on climate change research are divided into separate regions of the world with little knowledge exchange between them shows a new Danish-Brazilian study led by the University of Copenhagen. The most vulnerable countries of the world are largely disconnected from the production and flow of scientific knowledge on climate change, leaving their climate policymaking with little contextually relevant advice. The study calls for initiatives across private, governmental and non-governmental organisations, and from researchers themselves to diminish the knowledge gap.

When new research on climate change is published it most often concerns and is produced by the developed countries and the BRICS countries Brazil, India, China and South Africa rather than countries most vulnerable, but less contributing, to climate change.Study: Most Vulnerable Countries Know Least About Climate Change

The little research that does concern developing countries often lacks a locally based author. For instance, only about one fifth of the publications concerning climate change in Africa have a locally based first author - for the developed regions, it is two thirds of the publications. For some countries, such as the Republic of Congo and North Korea with up to 72 relevant publications, there are no locally based authors, not even co-authors.

"Without locally generated knowledge, it is more challenging to provide and integrate contextually relevant advice, and this leaves a critical gap in the climate policy debates. This is particularly worrying as we are dealing with countries likely to experience severe climatic changes and that are most sensitive to its detrimental impacts" says lead-author and postdoc Maya Pasgaard from the Department of Geosciences and Natural Resource Management at the University of Copenhagen.

In total, the study analysed author affiliations of more than 15.000 climate change publications published between 1999 and 2010. Authors focusing on the same countries for climate change research typically share geographical proximity, common climate, politics and economic characteristics.

"The regional divides limit critical flows of experiences and competencies across geographical and political-economic boundaries; a flow which is also needed to tackle the many threats and challenges of comparable character across regions, such as changes in crops, pest management and adaptation to climate hazards," says co-author and Professor Niels Strange from the Center for Macroecology, Evolution and Climate at the University of Copenhagen.

With the exception of some South American and African countries who share research interests, knowledge exchange on climate change suffers from large regional divides, in particular among vulnerable, developing regions.

The study recommends initiatives that focus on strengthening collaborations across geographical distances and across national differences in climate, export, democracy and national economy, as well as strengthening the local production and integration of knowledge.

Co-author and Assistant Professor Bo Dalsgaard from the Center for Macroecology, Evolution and Climate says:

"There is an array of partners responsible for increasing collaborations, ranging from big international organisations, such as the UN, to individual governments and higher education leaders. We also urge individual researchers and private companies alike to take responsibility for increasing cross-national collaborations and thus increase knowledge exchange between regions".

He is personally involved in a collaborative project across geographical, climatic and political-economic boundaries with UNICAMP in Brazil, the University of the West Indies in Jamaica, local coffee growers from, amongst other players, the Jamaican Coffee Growers' Association, and the London-based gourmet coffee brand Oubu Coffee. Together they study the effects of climate on the pollination of coffee in the Blue Mountains of Jamaica, West Indies.

"This project was initiated through a personal network between me, Oubu Coffee and their relations within Jamaica. As researchers we have to be willing to drive the transition forward through such opportunities and networks. Waiting for international institutions or governments to create new initiatives is not the only way forward" says Bo Dalsgaard.

Maya Pasgaard also has experience with research collaboration across regions, working together with a local researcher from Cambodia on community-based forest protection to mitigate climate change.

"Cross-border collaborations are not just highly relevant scientifically, but also rewarding on a personal level, as cultural knowledge exchange becomes an integrated part of the collaboration" she says.

The study is published online in the journal Global Environmental Change.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;

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."
