Climate change reshapes where people live, altering both the desire and the ability to move. When heat waves, droughts, and floods strike, not everyone responds the same way. A study in&nbsp;Nature Communications&nbsp;shows that age and education strongly influence who migrates and who remains.



The research reveals a complex story: extreme weather pushes some groups to leave while trapping others in place. This challenges the image of mass waves of <a href="https://www.earth.com/news/climate-wins-in-2025-came-from-unexpected-places/">climate</a> refugees often evoked in debates.

"Weather extremes can both incentivize people to move away and increase the number of people who don't have the ability to migrate," said Professor Benveniste.



"Our research shows that migration in response to weather, just like migration decisions in general, is highly dependent upon demographic characteristics."



<h2 class="wp-block-heading" id="h-climate-and-migration-patterns">Climate and migration patterns</h2>



Earlier research often gave mixed signals on whether women, men, or people with different education levels were more likely to migrate under extreme <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">weather</a>. 



By analyzing detailed global migration records, Benveniste and colleagues showed that these contradictions arise because responses vary sharply across demographics and local climates.



The team examined more than 125,000 cross-border cases and nearly half a million within-country moves. They categorized migrants by age, education, and sex, and then connected these groups to weather records like temperature and soil moisture. 



This approach revealed that migration is best understood not by how many move, but by who does.



<h2 class="wp-block-heading" id="h-trapped-and-cannot-migrate">Trapped and cannot migrate</h2>



The new model predicted migration up to 12 times better than previous approaches. Yet weather alone explained only a small fraction of migration, since economics, politics, and social ties also weigh heavily.



Still, striking demographic patterns emerged. Children under 15 were less likely to migrate following extreme heat. Older adults with little education, however, were more likely to leave, while highly educated adults showed little change.



"Our results indicate that many among those most likely to suffer from <a href="https://www.earth.com/news/earth-is-just-three-years-away-from-dangerous-carbon-milestone/">climate</a> change impacts will not be able to get out of harm's way," noted the researchers. 



This creates a "double penalty," where people with the fewest resources both struggle to adapt locally and lose migration as an option.



<h2 class="wp-block-heading" id="h-local-climate-and-migration">Local climate and migration</h2>



Climate zones shape how weather influences moves within countries. In tropical regions, hotter days increased migration among educated adults but had little effect on those with less schooling. 



In arid regions, dry spells spurred moves especially among the least educated, while heavy rains or flooding also triggered departures.



The analysis highlights how vulnerability interacts with opportunity. Those reliant on agriculture, often with little education, may feel a strong push to leave during drought, yet lack the means to relocate across borders. Instead, they may move to nearby towns or cities when conditions deteriorate.



<h2 class="wp-block-heading" id="h-who-migrates-and-who-doesn-t">Who migrates and who doesn't </h2>



The study emphasizes that climate change will not necessarily unleash waves of migrants. Instead, it will reshape the composition of those who move. 



Projections suggest that by the end of the century, older adults with little education may migrate across borders at higher rates, while the youngest and least educated will migrate less.



This shift means that population averages mask the real story: dramatic differences between groups cancel each other out. Policies that only consider total migration numbers risk overlooking those most affected.



<h2 class="wp-block-heading" id="h-responses-to-long-term-changes">Responses to long-term changes</h2>



The researchers caution that responses to long-term <a href="https://www.earth.com/news/wealthy-elite-responsible-for-majority-of-global-climate-warming/">climate</a> change may differ from reactions to short-term weather. 



Communities may adapt with new crops or technologies, reducing the need to move. Yet if conditions outpace these adaptations, migration pressures could rise again.



Destination conditions also matter. High heat in receiving countries can discourage movement for some groups, while wetter conditions may attract others, especially educated adults. 



Household factors, such as whether people have children, further influence decisions, with parents often less likely to move.



<h2 class="wp-block-heading" id="h-preparing-for-future-climate-shocks">Preparing for future climate shocks</h2>



Policymakers often prepare for large waves of climate refugees. But the evidence points to a subtler reality: climate change will alter who is able to move, while many vulnerable groups remain trapped.



"We hope that policymakers use these results as a basis to more squarely address the needs of different demographic groups," Benveniste said. "We need to answer the needs not just of the people who move, but also those who are moving less."



The science is clear: climate-driven migration is less about numbers and more about people. Understanding who moves, who stays, and why is key to preparing for a warmer, less predictable world.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-025-62969-3" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Climate shocks: Who migrates and who stays behind?

Climate change reshapes where people live, altering both the desire and the ability to move. When heat waves, droughts, and floods strike, not everyone responds the same way. A study in&nbsp;Nature Communications&nbsp;shows that age and education strongly influence who migrates and who remains.

A decade ago, environmentalists and the federal government agreed to revive a 150-mile stretch of California's second-longest river, an ambitious effort aimed at allowing salmon again to swim up to the Sierra Nevada foothills to spawn.
A major milestone is expected by the end of the month, when the U.S. Bureau of Reclamation says the stretch of the San Joaquin River will be flowing year-round for the first time in more than 60 years.
But the goal of restoring native salmon remains far out of reach.
The original plan was to complete the task in 2012. Now, federal officials expect it will occur in 2022. And the government's original estimate of $800 million has ballooned to about $1.7 billion.
"I think we all had hoped we'd be further along," said Doug Obegi, an attorney with the Natural Resources Defense Council, which led the lawsuit that produced the deal with the government to bring back salmon. "Restoring the state's second-largest river was never to be a cakewalk."
James Nickel is among the farmers in the fertile San Joaquin Valley region around Fresno questioning whether the project should go forward.
California is enduring a fifth year of drought, and many farmers have experienced sharp curtailments in water allotments from the government, leaving some fields fallow.
Nickel, a fifth-generation farmer to work land along the river, doubts the wisdom of spending money on an intricate system of passages to get salmon around the river's many dams and siphoning off more water from agriculture.
"Most practical folks would look at it and say, 'Impossible,'" Nickel said. "It seemed like a waste."
Scientists say salmon are a keystone species for the region. For thousands of years, salmon spawned and died, their decomposing bodies feeding nutrients into the valley soil, helping make it one of the nation's most prosperous farming regions.
The San Joaquin River spans 366 miles and is among the state's most dammed rivers. It starts as snowmelt high in the Sierra Nevada Mountains, cascades down through granite canyons and fills a reservoir at Friant Dam east of Fresno.
A few miles below Friant, the river has been running dry for much of the year. At Mendota, a community about 40 miles west of Fresno, the river resumes flowing with the help of various tributaries and eventually feeds into San Francisco Bay.
Before the U.S. Bureau of Reclamation opened Friant Dam in 1949, the river teemed with up to a half-million salmon a year and was deep enough that paddleboats transporting cargo could navigate far into to the San Joaquin Valley.
The dam gave farmers irrigation water that dramatically expanded agriculture but ended the salmon migration.
The Natural Resources Defense Council in 1988 set out to revive the river, filing a lawsuit that claimed the government's dam and irrigation channels favored commerce at the native salmon's expense.
The battle ended in a 2006 settlement that requires farmers to give up roughly 18 percent of the water captured behind Friant Dam. It also set an aggressive schedule to bring back natural salmon runs by 2012.
"It was a longshot, to say the least, that everything would be executed on that timeline," said Jason Phillips, who led early efforts by the U.S. Bureau of Reclamation to restore the river.
Today, he's CEO of the Friant Water Authority, which provides water primarily from the dam to growers irrigating 1 million acres of farmland. He calls it an "open question" whether the San Joaquin can be revived as envisioned under the settlement.
He said water for farms has become even scarcer since the settlement was reached with tightening regulations. And forecasts of climate change's impact on California's water supply weren't calculated into the deal, he said.
Adding complexity, officials say, in a 2012 attempt to flow the river, water seeped onto a farmer's field, destroying his tomato crop, a broad issue that has plagued the project.
Construction has not yet begun on passages for migrating salmon to swim around two dams on a lower stretch of the river that distribute water to farmers. Design for one abruptly halted in 2013, when engineers found the ground was sinking at an alarming pace - the result of farmers pumping groundwater to irrigate.
Meantime, state wildlife officials are raising salmon in tanks on the riverbank in small numbers and trucking them past obstacles to spawn. Plans call for reviving a migration of roughly 40,000 a year once the obstacles are cleared, allowing salmon to swim on their own from the Pacific up to the base of Friant Dam.
Money is another question. The project is to be paid for through state and federal sources. Much of the federal funding, however, needs Congress' approval each year, creating a degree of uncertainty, said Alicia Forsythe, current manager of the San Joaquin River Restoration Program for the Bureau of Reclamation.
Forsythe defended the project's slow pace, saying officials have spent time collaborating with farmers along the river rather than simply forcing the project on them.
Rene Henery, California science director for Trout Unlimited, a party to the lawsuit, said the state lost sight of the river's essential role in its rush to develop a vast system of dams, reservoirs and canals that spawned a thriving farm economy.
He noted other large government projects - bridges, airports and mass transit systems - often run over budget and past deadlines, but the benefits outweigh the costs in this restoration project.
The San Joaquin will help recharge the valley's depleted groundwater supplies that have caused the land to sink and will open recreation opportunities, spurring their own economic vitality, he said.
Most importantly, he said, salmon will again migrate from the Pacific hundreds of miles inland forming a critical link between the land and sea.
"Water is the most important element for life on this planet," Henery said. "Our rivers, they're the vascular system of our landscape and of our societies."

Salmon will soon swim up the San Joaquin River again to spawn

New research published in Scientific Reports this week suggests that some members of the dinosaur family may have made an epic journey about 100 million years ago.

These intrepid explorers traveled from South America and crossed over Antarctica to Australia during a warm spell, which would have allowed passage over previously frozen land.

Two recent fossil discoveries in Australia have added evidence to this theory. Both specimens are sauropods from the titanosaurs group, very large herbivorous dinosaurs with small heads and long necks.

Dr. Stephen Poropot of the Australian Age of Dinosaurs Museum said, “As a result [of this discovery] we can start piecing together how climate affected these dinosaurs, how the positions of the continents affected those dinosaurs and how they evolved through time as well."

One of the dinosaurs has been named Savannasaurus elliottorum, after members of the family who found the fossil near Winton in Central West Queensland. The skeleton was encased in rock and took 10 years to extract.

The team also uncovered head bones from another sauropod. "This new Diamantinasaurus specimen has helped to fill several gaps in our knowledge of this dinosaur's skeletal anatomy," said Dr Poropat.

These specimens show that titanosaurs were living intercontinentally 100 million years ago.

Climate change revealed additional land on and between the continents, making travel possible.

"We suspect that the ancestor of Savannasaurus was from South America, but that it could not and did not enter Australia until approximately 105 million years ago," he said."At this time global average temperatures increased, allowing sauropods to traverse landmasses at polar latitudes."

According to scientists at the Woods Hole Oceanographic Institution (WHOI), ocean temperature changes affect a key species of phytoplankton. Published in the journal <a href="https://www.nsf.gov/news/news_summ.jsp?cntn_id=190021&amp;WT.mc_id=USNSF_51&amp;WT.mc_ev=click" target="_blank" rel="noopener">Science</a> this week, their study tracked levels of Synechococcus, a bacterium common in marine ecosystems, near the coast of Massachusetts over a 13-year period.

"Synechococcus and other phytoplankton are sentinels," says WHOI biologist Heidi Sosik, who initiated the study. "They tell us how an ecosystem is responding to shifts in climate."

With ocean temperatures rising, the annual blooms of Synechococcus appeared several weeks earlier, as cells divide faster in warmer waters. These shifts may have major implications for marine ecosystems worldwide.

If this trend continues, some ecosystems may become dominated by small phytoplankton which would eventually affect larger species like fish, whales, and birds. Although Sosik and colleagues did see that Synechococcus cells reproduced faster in warmer conditions, the overall size of the phytoplankton bloom didn't increase much throughout the study. In fact, single-celled organisms that prey on Synechococcus consumed them more quickly, thus balancing the bloom cycle.

"The question is: How stable is that balance?" asks Kristen Hunter-Cervera, lead author of the paper. "In the future, will consumer species be able to keep up? A mismatch is a huge concern. If the bloom expands or moves earlier in the year, higher-level organisms that feed on those consumers at a certain time of year might miss them entirely."

The team used an automated sensor called "FlowCytobot," which continually sampled seawater during the course of the experiment.

Climate change is disrupting the sensory systems of fish and can even make them swim towards predators, instead of away from them, a paper by marine biologists at the University of Exeter says.

Research into the impact of rising CO2 has shown it can disrupt the senses of fish including their smell, hearing and vision.

High CO2 levels can impair the way they behave, including making them swim towards predator smells instead of away and even ignoring the sounds that normally deter them from risky habitats.

According to a paper published today in the journal Global Change Biology by Dr Robert Ellis and Dr Rod Wilson, climate-change marine biologists at Exeter University, these abnormal behaviours have been linked to the effect of CO2 on how the brain processes signals from sensory organs.

CO2 levels are predicted to be 2.5 times higher in the oceans by the end of this century.

The report's authors Dr Robert Ellis and Dr Rod Wilson believe that fish farms, may be the key to establishing the long-term impact of CO2 on marine life.

In their paper, Lessons from two high CO2 worlds: future oceans and intensive aquaculture, Dr. Ellis and Dr. Wilson, alongside a colleague from Chile (Dr. Urbina), show that farmed fish often live in CO2 conditions 10 times higher than their wild cousins.

The scientists believe that further study of farmed fish - which already provides as much seafood for human consumption as that caught in the wild - may be crucial for understanding how aquatic species will evolve to climate change.

The captive fish farm populations living in high CO2 levels already amount to "a giant long-term laboratory experiment".

"Aquaculture may provide an 'accidental' long-term experiment that can help climate-change predictions," said Dr. Ellis. "There is the enticing possibility that fish and shellfish previously grown in high CO2 aquaculture conditions over multiple generations can offer valuable insights regarding the potential for aquatic animals in the wild to adapt to the predicted further increases in CO2."

The aquaculture industry may also benefit from what the climate change scientists study too. The abnormal behaviour seen in wild fish may not matter in farmed fish, as they are provided with abundant food and shelter and they have no predators to avoid. But while extremely high CO2 can reduce digestion efficiency in cod, recent research suggests that relatively small increases in CO2 may actually act as a growth stimulant in some fish.

Dr. Rod Wilson said: "Our research will allow fish farmers to optimise conditions, and specifically CO2 levels, to improve growth and health of their fish, profitability and the long-term sustainability of the industry. This is really important given that aquaculture is the only way we will increase seafood production to feed the growing human population, particularly given wild fish stocks are overexploited".

Snow Leopard Stalking Prey

New report sparks sad news for the endangered snow leopard.
According to a new report, there only 4000 snow leopards living today due to poachers killing them daily in the high mountain ranges of Asia.
Many of these incidents are said to be revenge killings in response for wildstock losses.
The report also states that the illegal leopard skin trade has moved online to outwit authorities.
Snow leopards thrive in high altitudes. Their propensity to hunt domestic sheep and cattle puts them in hot water with farmers. This new study approximates that over 3000 snow leopards have been poached since 2008 – the authors believe the cause is the conflict between humans and the animals.
"We think that what most observations, seizure records and expert opinion shows is that the majority is still happening because of retaliatory killing," said James Compton from TRAFFIC, the wildlife trade monitoring network.
The writers of the report suggest that creating better livestock protection in the nomadic, remote communities is a major remedy for this issue. The majority of the poaching has occurred in China, Mongolia, Pakistan, India and Tajikistan. The research suggests that a minority of the snow leopards – only 21% – were poached for the illegal fur trade.
The report calls for greater law enforcement cooperation across international borders during poaching investigations. The writers also suggest creating an incentive structure to empower local communities in order to help the snow leopards’ plight.
"Even if there is reduced demand for snow leopard skins, the killing will continue unless we all work together to drastically reduce human-wildlife conflict," said Rishi Sharma of the World Wildlife Fund, co-author of the report.

Predators employ two main strategies in their quest for prey. Some hunt in groups and share the bounty. Others go solo, with hopes of a meal all for themselves.

It would seem a complex combination of ecological factors influence the dynamics of predation, but a team of scientists have found a way to simplify the sociology of the hunting party.

In a new study published in the journal PLOS ONE, a team of researchers from Princeton University and the Stockholm Resilience Centre have detailed a few rules of thumb to determine whether a predator is more likely to seek out cooperation or go it alone.

Scientists say their findings could be used to better understand the behavior of any group competing for limited resources, whether they be lions, day-traders or fishermen.

"This boils down to one central trade-off: the benefit of acquiring information about prey location, and the cost of sharing prey with other predators," James Watson, a researcher at the Stockholm Resilience Centre, explained in a news release.

Watson and his research partners studied how the distribution of prey and the specifics of the hunt influenced the dynamics of both human and animal predators. Their analysis showed that the longer it takes to find the prey, and the longer it takes to harvest and consume the prey, the more likely a predator is to cooperate with others.

"Fishermen tend to share information about salmon or other migratory species," Watson said. "But they're more secretive and even territorial about fish stocks that remain more or less in the same place. In Scandinavia mushroom hunters are quite secretive about the location of wild mushrooms in forests, for example."

Researchers also identified and calculated the three main factors that influence the rate of prey consumption by predators: how quickly prey move, how quickly scavengers and other predators find killed prey, and how quickly scavengers and other predators eat the prey after it's found.

"A large buffalo takes a long time to consume, so over this time period, other predators might move in and share the meat," Watson explained.

Watson and his colleagues are now working on the arithmetic that explains how different environments alter the cost-benefits of sharing information.

"We want to identify evolutionary stable strategies in social groups," he added. "This will help us understand how animals, people and businesses collectively organize around resources."

NASA has made history by releasing the first full analysis of the life cycle of a flood in the journal <a href="http://agupubs.onlinelibrary.wiley.com/agu/journal/10.1002/(ISSN)1944-8007/" target="_blank" rel="noopener">Geophysical Research Letters</a>. The research, which focuses on a 2015 Texas flood, shows the impact on both land and ocean. The data was reported by NASA's Soil Moisture Active Passive (SMAP) satellite and other satellite instruments. It followed the flood, starting with the rains that fell weeks before and ending with an unusually-shaped plume of freshwater that lingered in the Gulf of Mexico months later.

The flood occurred last May following record rainstorms and weeks of continuous rainfall in Texas. According to the National Weather Service, the 37.3 trillion gallons of water was enough to cover the whole state in 8 inches of water. The floods were responsible for 11 deaths and significant impacts on local and ocean ecology, as well as causing millions of dollars in damage.

“The sheer amount of water was shocking," said co-author J.T. Reager of NASA.

SMAP measures soil moisture and sea levels. From these readings, the scientists learn how much freshwater has been added to the saltwater of the ocean.

This analysis revealed that eight Texas rivers drained huge volumes of water into the Gulf of Mexico at rates of up to 1,700 cubic feet per second. As the rain was falling on the already waterlogged terrain, the only place for it to go was downstream.

River waters carry pollutants into the ocean which can have a large impact on the ecology of the ocean. In extreme cases, the reactions create a dead zone which is an area so oxygen-starved that no living organism can survive there.

The Gulf of Mexico already has a large dead zone. Following the Texas flood, the dead zone increased by 28%, causing negative effects for both fish and the local economy. 

The research team is set to dive deeper into the impacts in a follow-up study. They hope their research can help in creating predictive models for extreme weather situations. These, in turn, can assist ecologists and local communities in preparing for such weather.

NASA research tells the life story of a flood

NASA has made history by releasing the first full analysis...

The Environmental Protection Agency had sufficient authority and information to issue an emergency order to protect residents of Flint, Michigan, from lead-contaminated water as early as June 2015 - seven months before it declared an emergency, the EPA's inspector general said Thursday.
The Flint water crisis should have generated "a greater sense of urgency" at the EPA to "intervene when the safety of drinking water is compromised," Inspector General Arthur Elkins said in an interim report.
Flint's drinking water became tainted when the city began drawing from the Flint River in April 2014 to save money. The impoverished city of 100,000 north of Detroit was under state control at the time. Regulators failed to ensure water was treated properly and lead from aging pipes leached into the water supply.
Federal, state and local officials have argued over who's to blame as the crisis continues to force residents to drink bottled or filtered water. Doctors have detected elevated levels of lead in hundreds of children.
A panel appointed by Michigan Gov. Rick Snyder concluded that the state is "fundamentally accountable" for the lead crisis because of decisions made by state environmental regulators and state-appointed emergency managers who controlled the city.
Even so, Snyder and other Republicans have faulted the EPA for a slow response.
"As Gov. Snyder has stated all along, what happened in Flint was the result of failure of government at all levels," spokeswoman Anna Heaton said Thursday.
State agencies have undergone "culture changes" and updated procedures to prevent a recurrence, so "it's encouraging to see other agencies undergoing evaluations that can result in improvements to help people here and across the nation," Heaton said.
Flint Mayor Karen Weaver called the report "deeply troubling."
Weaver, a Democrat who took office after the Flint crisis emerged, said agencies such as the EPA and the Michigan Department of Environmental Quality are "in place to help ensure the well-being and safety of men, women and children, yet they failed when it comes to the man-made water disaster in Flint. Those responsible must be held accountable."
The report by the inspector general says officials at the EPA's Midwest region did not issue an emergency order because they concluded that actions taken by the state prevented the EPA from doing so. The report calls that interpretation incorrect and says that under federal law, when state actions are deemed insufficient, "the EPA can and should proceed with an (emergency) order" aimed at "protecting the public in a timely manner."
Without EPA intervention, "the conditions in Flint persisted, and the state continued to delay taking action to require corrosion control or provide alternative drinking water supplies," the report said.
Michigan officials declared a public health emergency in October 2015; the EPA declared an emergency three months later.
EPA Administrator Gina McCarthy has acknowledged that her agency should have been more aggressive in testing the water and requiring changes, but told Congress that officials "couldn't get a straight answer" from the state about what was being done in Flint.
Spokeswoman Monica Lee said Thursday that EPA issued an order in the Flint case "as soon as it became apparent that the city and state were failing to address the serious problems with the Flint drinking water system."
The director of the EPA's Midwest regional office stepped down Feb. 1 amid withering criticism that the agency failed to act sooner to address lead contamination in the predominantly African-American city.
The official, Susan Hedman, denied wrongdoing, but said she was leaving to avoid becoming a distraction.
In a memo from June 2015, Miguel Del Toral, a scientist in the EPA's Midwest office, had warned of dangerously high levels of lead. He later criticized the agency for not taking swift action.
The inspector general's office said a final report on Flint is still being developed. Separately, criminal investigators with the IG's office are assisting in an ongoing probe of the Flint crisis being led by the U.S. attorney's office.

Group: The EPA waited seven months to intervene in Flint water crisis

The Environmental Protection Agency had sufficient authority and information to...

Only a small share of Congolese villagers is the driving force behind most of the deforestation. They're not felling trees to feed their families, but to increase their quality of life. These findings are based on fieldwork by bioscience engineer Pieter Moonen from KU Leuven (University of Leuven), Belgium. They indicate that international programs aiming to slow down tropical deforestation are not sufficiently taking local farmers into account.</div>
Forests, and especially centuries-old primeval forests such as in the Congo Basin in Africa, are huge CO2 reservoirs. When trees are cut down, large amounts of greenhouse gases are released. This contributes to climate change - both regional and global.

The Democratic Republic of the Congo (DRC) is in the world's top five in terms of amount of deforested land per year. According to the government, this is mostly due to subsistence farming and population growth. The argument is that small farmers grow crops to feed their own families. As there is a rise in population, farmers have to keep on clearing forest to increase the area under cultivation.

Bioscience engineer Pieter Moonen is preparing a PhD on land use and climate change in the DRC. He examined whether subsistence farming really is the main culprit for deforestation. For a year, he did fieldwork in 27 Congolese villages and questioned 270 households in a survey about agriculture and deforestation.

[caption id="attachment_90224" align="alignleft"]<img class="size-thumbnail wp-image-90224" src="http://www.earth.com/wp-content/uploads/2016/10/cff2.earth-com-temp.comuploads20161021031042media.eurekalert.orgmultimedia_prodpubweb125265_web-8b27800f87fdfbd0eb623e21f6b84da096979062-61a155a9bd51eb92d64fbc303a5d13a7e68e4ca1-150x150.jpg" alt="deforestation in the central Congo Basin" width="150" height="150" /> deforestation in the central Congo Basin[/caption]

"Most of the people surveyed are farmers, and only half of them deforest. A very small group is behind most of the deforestation. Their motive is not self-sufficiency, but earning money. After all, selling crops on the market is one of the few ways to get cash. They need this money to cover the increasing cost of education and health care or to buy western consumer goods. The image of the poor farmer felling trees to feed his family is therefore incorrect. The slightly richer farmers are the ones deforesting to sell their agricultural produce on the market- although 'rich' is very relative in this case." A second important motive for deforestation is the possibility to claim the land that has become available as your property.

These findings are important for the implementation of the United Nations REDD+ programme. REDD+ stands for reducing emissions from deforestation and forest degradation. This initiative aims to slow down or end deforestation in developing countries by means of financial incentives.

"Now that the Paris Agreement on climate change is about to take effect, REDD+ is receiving a lot of attention. The Democratic Republic of Congo is interested in taking part: they want to fight deforestation in exchange for financial compensation. But their response to deforestation focuses too much on intensifying agriculture - increasing the amount of produce per hectare. The reasoning is that felling trees is no longer necessary if existing fields yield more produce. This is an effective strategy when dealing with subsistence farming, but it may have a perverse effect when applied to commercial agriculture. After all, it may stimulate the wealthier farmers to deforest more land, so that they have even more produce to sell. Therefore, without local support for forest preservation, the outcome of such interventions is very uncertain. In that case, we risk wasting money and valuable time with REDD+."

This study once again shows that a simple government approach to deforestation is not effective, Moonen continues. "A more effective and fair approach requires that you and the local communities reach a consensus on a sustainable system. This means that you have to agree on which areas are protected forest. You also have to set aside the necessary resources to support development: provide basic facilities and create opportunities to increase revenues, in the agricultural system and beyond."

Typhoon Haima barreled into southern China on Friday after hammering the northern Philippines with ferocious wind and rain, triggering flooding, landslides and power outages and killing at least 13 people.
Chinese meteorological services said the typhoon made landfall shortly after noon in the city of Shanwei in Guangdong province, packing winds of up to 166 kilometers (103 miles) per hour before weakening to a tropical storm.
No major damage was immediately reported, though reports said some villages had experienced power outages and officials were on alert for heavy flooding and landslides.
China had suspended dozens of flights and rail services in several southern provinces. In the city of Shenzhen, authorities ordered schools, markets and factories to close, halted public transportation and evacuated some areas.
Hong Kong hunkered down as Haima lashed the financial hub with rain and wind gusts of up to 109 kph (68 mph). Schools and offices were shut, trading on the stock market suspended and commuter ferry services halted after the third most serious storm signal was hoisted, leaving an eerie calm in the streets of the normally bustling city. More than 740 flights to and from the city's international airport were canceled or delayed. By early afternoon, the storm was about 110 kilometers (70 miles) east of the city and moving away.
In the Philippines, Haima's blinding winds and rain on Thursday had rekindled fears of the catastrophe wrought by Typhoon Haiyan in 2013, which left 7,300 dead, but there has been no report of any major damage. Large casualties appeared to have been averted after more than 100,000 people fled to safer ground. Several villages were cut off by fallen trees, landslides and floods, impeding communications and aid.
At least 13 people were killed, mostly in landslides and floods, in the fast-moving storm, officials said. But the evacuations from high-risk communities helped prevent a larger number of casualties and thousands were still in emergency shelters due to a powerful that hit the north a few days.
The extent of damage in Cagayan, about 500 kilometers (310 miles) north of Manila, where the typhoon made landfall, was evident in overturned vans, toppled or leaning electric posts and debris blocking roads. Most stores, their window panes shattered and canopies shredded by the wind, were closed.
President Rodrigo Duterte, on a state visit to China, urged people to heed orders by disaster agencies. Duterte is to fly home Friday.

Federal forecasters predict this winter may paint the U.S. in stripes of different winter weather: Warmer and drier than normal in the south, and colder and wetter than usual in the far north.
The National Weather Service winter outlook , issued Thursday, gets murky in the nation's middle belt, with no particular expectation for trends in temperature or precipitation.
Still, some nasty storms might make the winter there memorable, said Mike Halpert, deputy director of the weather service's Climate Prediction Center.
The major driver of the winter forecast is a budding La Nina, a cooling of the central Pacific that warps weather worldwide and is the flip side of the better-known El Nino, Halpert said.
For the South and California, "the big story is likely to be drought," Halpert said.
And that's not good news for California, which is in year five of its drought. The winter is the state's crucial wet season when snow and rain gets stored up for the rest of year. Halpert said the state's winter looks to come up dry, especially in Southern California.
"It's probably going to take a couple of wet winters in a row to put a big dent into this drought now," said weather service drought expert David Miskus. He said it will take "many, many years and it's got to be above normal precipitation."
The northern cold band that the weather service predicts is mostly from Montana to Michigan. Maine is the exception, with unusually warm weather expected.
The prediction center's track record on its winter outlooks is about 25 percent better than random chance for temperature and slightly less than that for precipitation, Halpert said.
Private weather forecasters are predicting quite a different winter. They foresee a harsher one for much of the nation, including a return of the dreaded polar vortex, which funnels cold Arctic air into the U.S.
Judah Cohen of Atmospheric and Environmental Research in Lexington, Massachusetts, forecasts an unusually cold winter for the eastern and middle two-thirds of the nation, especially raw east of the Mississippi River.
Cohen, whose research is funded by the National Science Foundation and closely followed by meteorologists, links North America's winter weather to Siberian snow cover in October.
He agrees that Maine will have a warm winter, and also predicts a warm Southwest.
The private Accuweather of State College, Pennsylvania, calls for frequent storms in the Northeast, early snow in the Great Lakes, bitter cold in the northern tier and occasional cold in the middle. Like other forecasters, it predicts a warm and dry southwest, with some hope for rain and snow from San Francisco northward.

In December 2015, history was made in Paris as 195 countries adopted the first-ever universal, legally binding global climate deal. In a press release dated August 8th, 2016, Republican presidential nominee Donald Trump courted controversy by stating he hoped to <a href="https://www.donaldjtrump.com/press-releases/unleashing-americamericas-prosperity-to-create-jobs-and-increase-wages">cancel the agreement</a> if he is voted into power. Politics aside, new <a href="http://www.iiasa.ac.at/">IIASA</a> research released today helps us understand how The Paris Agreement will be enforced in 2020.
In a new article published in the journal Science, the researchers suggest a structure for helping vulnerable communities adapt, survive and become more resilient in the ever-changing landscape of irreversibly changing climates.
"The impacts of climate change are being felt on all continents and in every ocean on the planet," says Reinhard Mechler, a researcher at the International Institute for Applied Systems Analysis (IIASA) and the Universities of Vienna and Graz.
The authors state that some countries will need assistance to respond to the agreement. Using climate risk analysis data, the authors have suggested a framework for identifying risks and implementing curative measures.
These findings will be presented on November 7th, 2016 at<a href="http://www.cop22-morocco.com/"> COP22 </a>in Marrakesh, Morocco.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

</div><figcaption class="wp-element-caption">Acid rain and a crisis solved.</figcaption></figure>



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

Wildlife tunnels save millions of amphibians

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

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



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



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

</div></figure>



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."

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.
