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.



Study lead author Hélène Benveniste is an assistant professor of environmental social sciences at the <a href="https://sustainability.stanford.edu" target="_blank" rel="noreferrer noopener">Stanford Doerr School of Sustainability</a>.



"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.

Relentless rain and snow has already done what experts said could take years in much of Northern California: ended more than five years of drought, or at least come very close. But the rain didn’t stop there.

Now, thousands of people across the northern part of California and in northeastern Nevada slowly flooding. Parts of Idaho, Oregon, and Utah have also seen extreme weather this week.

But California and Nevada have borne the brunt of the relentless rain that has streamed into the U.S. from the Pacific since the beginning of January.

Sacramento has received just over 15 inches of rain since January 1, according to the private monitoring website <a href="https://www.wunderground.com/">Weather Underground</a>. That’s three times higher than the average rainfall from January 1 to February 10.

San Francisco has gotten 12.71 inches, more than twice its year to date average. Eureka has received more than 15 inches, not quite double its average.

The story is the same all over California, but it’s the precipitation in the mountains that is causing the most problems.

Storms since November of last year have dropped dozens of feel of snow in the high Sierra. The same storms saturated the ground at lower elevations until it could no longer absorb any more moisture, and filled the rivers.

Rain and snowfall have been anywhere from 150 to 300 percent of normal for much of Northern California, according to private forecasting firm <a href="http://www.accuweather.com/en/weather-news/warmth-to-precede-new-train-of-storms-in-western-us-next-week/70000816">AccuWeather</a>. In that time, reservoirs across the state have gone from near empty to overflowing.

The storm that brought even more rain to Northern California last week also brought warm temperatures. In the lower elevations, at least, all that snow is melting – and it has nowhere to go.
<h3>A look at the damage</h3>
It’s causing chaos throughout the state. On Friday, <a href="https://www.gov.ca.gov/">Gov. Jerry Brown</a> expanded his state of emergency from 49 counties – already swamped by storms in January – to 52, and formally requested a Presidential Major Disaster Declaration.

“This series of powerful winter storms brought relentless heavy precipitation and high winds that caused flash flooding, debris and mud flows, erosion, power outages, and damage to critical infrastructure,” the governor said in his <a href="https://www.gov.ca.gov/docs/2.10.17_Letter.pdf">request</a> [PDF].

Mudslides closed two major routes into the Sierra on Friday, Interstate 80 and Highway 50. I-80 was reopened Saturday, but Highway 50 would be closed until at least Sunday night, the <a href="http://www.dot.ca.gov/">California Department of Transportation</a> announced.

Flooding also restricted traffic on some major roadways, including Highway 99 through the Central Valley and Highway 37 in Sonoma and Marin counties.

The ground in many places simply cannot handle any more moisture.

A mudslide slammed into a house in Orinda, in Contra Costa County. Mudslides in Marin County forced a <a href="http://sanfrancisco.cbslocal.com/2017/02/09/mother-toddler-escape-massive-fairfax-mudslide/">woman and her 4-year-old son</a> to escape through a bathroom window as their house was destroyed. They were two of a handful of homes destroyed as ground gave way after weeks of relentless rain.

And a freight train carrying food derailed on Friday, sending 22 cars into the swollen Cosumnes River in Sacramento County. Flooding was a likely factor, Union Pacific told the <a href="http://www.sacbee.com/news/local/transportation/article132227414.html">Sacramento Bee</a> on Saturday. The derailment caused no injuries.

“With all that water that was there, it’s not typical,” <a href="http://www.up.com/">Union Pacific</a> spokesman Justin Jacobs told the newspaper. “That whole area around (the tracks) is near a river that was overflowing.”

Levees throughout the San Joaquin Valley have broken, along the Cosumnes River south of Sacramento, Paso Creek near Bakersfield, Pacheco Creek near Hollister, and beyond, swamping homes and farmland. A dam break in Nevada’s Elko County led to flash flood warnings.

But the disaster waiting to happen that has the state transfixed is the massive hole in the Oroville Dam’s spillway. The hole, estimated at about 250 feet long and 45 feet deep, opened up on Tuesday.

For the very first time in its history, the dam’s emergency spillway was put into use. Officials had no choice: Lake Oroville was completely full and had begun overflowing at the emergency spillway anyway.
<h3>Could more relentless rain be on the horizon?</h3>
The rainy weather is taking a short break in Northern California, for the early part of this week.

But the dry weather is not expected to last, according to private forecasting firm AccuWeather. Rain is likely to move back in by Thursday – another Pacific storm bringing heavy snow and relentless rain.

There should be some warm, dry weather in the days before the rain picks back up, AccuWeather said. That could allow homeowners and public employees to begin cleaning up from recent flooding and landslides.

Or it could cause new problems.

“The rise in temperatures will continue to cause localized flooding due to melting snow and ice jams in the Intermountain West,” AccuWeather Senior Meteorologist Kristina Pydynowski said. “Low-lying and poor drainage areas, as well as locations along streams and rivers are most at risk for the flooding.”

In California, that could mean more mudslides and more flooding as snow in the Sierra melts.

It’s too early to tell with any certainty what the weather might do beyond next week’s storms, but the rest of February could be wet, too, AccuWeather said.

People are already drawing comparisons to the New Year’s flood of 1997, but it’s another flood that has some people nervous.

The conditions – relentless rain and snow, plus unseasonably warm temperatures – could potentially lead to flooding like the state hasn’t seen in more than 150 years.

During the Great Flood of 1862, atmospheric rivers from the Pacific Ocean brought more than 40 days of unceasing rain and snow. They also brought intermittent warm spells that melted much of that snow.

Hyper-saturated ground unable to absorb water and snowmelt pouring out of the Sierra Nevada mountains turned the Central Valley into a massive inland lake.

That series of storms also brought relentless rain and floods to Oregon, Idaho, Nevada, Utah, and throughout the western U.S. and northwestern Mexico.

In 2011, the <a href="https://www.usgs.gov/">U.S. Geological Survey</a> released a report, <a href="https://pubs.usgs.gov/of/2010/1312/">ARkStorm</a>, that found similar flooding events happen about every 100 to 200 years on the West Coast. <a href="http://www.earth.com/news/extreme-rainfall-new-norm-california/">Studies</a> released by the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a> and the <a href="https://www.ucdavis.edu/">University of California, Davis</a> in the fall warned that a major flood could be coming.

Hopefully, the West will dry out a bit this week before the wet weather returns, and we'll avoid a 100-year flood.

In the meantime, keep an eye on the <a href="http://www.weather.gov/">National Weather Service</a> for extreme weather alerts.

Relentless rain floods California, Nevada and the West

Relentless rain and snow has already done what experts said...

A three-foot shift in sea level might not sound like that much to most of us. To those who actually live within three feet of sea level, however, it sounds like a lot.

That’s why news of a sea level change that occurred in Southeast Asia 6,000 years ago is attracting major attention. Adding to the concern is the discovery that this fluctuation happened without humans influencing a change in <a href="http://www.earth.com/news/pre-industrial-climate-baseline/">climate</a>. 

A group of oceans scientists and statisticians reported that starting 6,850 years ago, the relative sea level around Belitung Island in Indonesia rose approximately two feet in 350 years. This shift happened without any human-assisted climate change, which suggests that any future sea level rises could be a significant: a combination of a natural rise in sea level plus that caused by climate change that’s been set in motion by humans. 

"This research is a very important piece of work that illustrates the potential rates of sea-level rise that can happen from natural variability alone," says Benjamin Horton of<a href="http://www.rutgers.edu"> Rutgers University</a>. "If a similar oscillation were to occur in East and Southeast Asia in the next two centuries, it could impact tens of millions of people and associated ecosystems.”

Lead author Aron Meltzner from<a href="http://www.apple.com"> Nanyang Technological University</a> and the rest of the team studied coral microatolls to learn about the rise and fall of sea levels in the area around Belitung. A microatoll is a coral colony with dead layers on top and living layers beneath. Scientists can study the layers of coral much the way archaeologists study layers of rock. The microatolls helped the team determine general dates when sea levels rose and fell.  

The findings, published in<a href="http://www.nature.com/ncomms/"> Nature Communications</a>, are of particular concern to those who live extremely close to the sea. Researcher hope that by understanding what happened in the past, they will be better able to predict what kind of changes to expect in the future.

Scientists have recently discovered four hidden lakes beneath the Thwaites glacier in <a href="http://www.earth.com/image/warming-antarctic-bottom-waters/">Antarctica</a>. Hooray, right? 

No hooray. What sounds like an exciting scientific discovery could be somewhat speeding up the demise of the glacier, sending it slip-sliding into the ocean. 

Once the Thwaites glacier is lost, it is expected to destabilize the West Antarctic Ice Sheet and cause the seas to rise approximately two feet across the globe. 

The team of researchers from the<a href="https://www.washington.edu"> University of Washington</a> and the<a href="http://www.ed.ac.uk"> University of Edinburgh</a> found four lakes – all interconnected – lurking beneath the glacier. The glaciers emptied themselves between June 2013 and January 2014. 

Scientists were able to use data from CryoSat-2, a European Space Agency satellite, to monitor the drainage of the lakes.

Benjamin Smith, a professor at University of Washington and a glaciologist at their Applied Physics Laboratory, explained, “This was a big event, and it confirms that the long-term speed-up that we’re observing for this glacier is probably driven by other factors, most likely in the ocean. The water flow at the bed is probably not controlling the speed.”

The team’s findings were published in the journal<a href="http://www.the-cryosphere.net"> The Cryosphere</a>. 

The researchers used a new method to discover that there are drops in the glacier’s surface where each lake is located. The lakes are large, with the biggest one measuring 8,500 cubic feet – roughly the size of Lake Washington. As for their drainage rate, the water flowing out moved at around half the flow rate of the Hudson River. 

During the years in which the lake drainage data was measured, the glacier’s slipping speed increased by 10%. However, scientists aren’t sure that the drainage of the lakes was the cause for the increase in glacier movement. They feel that another possible cause is warm seawater moving around underneath the glacier.

“This lake drainage is the biggest water movement that you would expect to see in this area, and it didn’t change the glacier’s speed by that much,” Smith said.

One of the engineering wonders of the world, the Panama Canal is a 48-mile waterway that cuts across the Isthmus of Panama to connect the Atlantic and <a href="http://www.earth.com/news/noaa-federal-waters-fish-farming/">Pacific Oceans</a>. First opened in 1914, the canal has seen big changes in the world over the past century. 

One of those changes – an increasing size in cargo ships, was the reason behind a canal expansion that began last year. 

Lately, though, the expansion has hit some snags. Specifically, large cargo vessels traveling through the canal are hitting snags. They’re scraping up against the walls and experiencing nail-biting near-misses when steel lock doors installed throughout the systems fail to open all the way. 

That’s what happened to the cargo ship Ever Living when it traveled through the canal while carrying more than 6,000 cargo containers. Although the ship made it through, they passed extremely close to the side of the locks as they made their way through the last of the steel doors.

It was too close, according to Mauricio Perez, a tugboat captain. 

These are things that shouldn't happen," he said to the <a href="https://www.ap.org/en-us/">Associated Press</a>. "Sometimes the only thing we can do is pray."

The AP took its own journey through the updated canal and noted areas where the black rubber bumpers meant to keep ships from colliding with metal locks were worn or missing entirely. Because maneuvering large ships through the canal is incredibly difficult, sometimes captains must purposefully send a ship into a bumper in order to realign the vessel as it moves forward. This results in a huge amount of wear and tear on the protective cushions. 

Only 15 incidents occurred between June 2016 and January of this year, the Panama Canal Authority says. They say that the door lock incident was caused by debris collecting on a water-level sensor and that the problem has been resolved.

The authority isn’t ruling out future changes. Currently, though, the deputy administrator of the canal, Manuel Benitez, feels positive about the way personnel are navigating vessels through the treacherous canal. “The ships have not run aground; they continue their routes,” he said.

Hey! – at least there’s that.

Twenty-four family <a href="http://www.earth.com/news/lost-topsoil-farmers-switchgrass/">farmers</a> have something to crow about: they were just awarded grants from<a href="https://foodanimalconcernstrust.org"> Food Animal Concerns Trust</a> (FACT) via the organization’s<a href="http://www.fundafarmer.org"> Fund-a-Farmer Project</a>. 

FACT was founded in 1982 in order to promote humane farming practices. It advocates for the safe production of meat and dairy products and works to help consumers make good choices in the products they purchase. 

On their website, FACT says that they believe “that all farm animals should be granted adequate space, access to the outdoors, clean water and air, the opportunity to express their natural behaviors, and safe feed.”

The Fund-a-Farmer Project grew out of that mission. It awards grants and provides the opportunity for peer-to-peer farmer education around humane animal farming practices. 

FACT realizes that oftentimes, farmers want to make positive changes in the way they raise their animals, but these changes often chest money. By providing financial assistance, FACT hopes to make those changes a reality.

This year, farms in 15 different states received Fund-a-Farmer grants. Nine farms won Animal Welfare Certification grants, while 15 farms won grants for pasture improvement projects. 

This year’s grants bring FACT’s total awards to 91 grants across 27 states since the Fund-a-Farmer Project began in 2012. In that time, FACT has awarded over $57,000 in grants. 

Larissa McKenna, FACT’s Humane Farming Program Director, explained that they hope these grants will help individual farmers, as well as food consumers, in general.

“Today, an increasing number of people want to know where their food comes from, who produces it, and how it was grown," McKenna said. "Small and mid-sized sustainable farms are essential to meeting consumer demand for humanely-raised food, but often face financial challenges due to high costs associated with economies of scale. Our organization supports these farms by funding projects that improve animal welfare and also help farmers increase their profit margins.”

The Dakota Access pipeline is moving forward. In a statement on Tuesday, the United States <a href="http://www.usace.army.mil/">Army Corps of Engineers</a> said that it will grant the easement needed for the project to be completed. 

The Corps has also terminated plans to issue an Environmental Impact Statement on the project – a process that President Donald Trump had asked to be expedited. 

The announcement comes as a blow to <a href="http://www.earth.com/news/womens-march-speak-trump/">protesters</a> who have been camped out near Cannon Ball, North Dakota, for months. Those opposed to the Dakota Access pipeline say that it poses a danger because it will run underneath a lake that’s a source of drinking water for Native American tribes in the area. 

Protesters briefly celebrated when the project was halted for some time in December – a decision made by the Obama administration. Even then, Energy Transfer Partners, the company responsible for building the pipeline, said that it was determined to complete construction without rerouting the pipeline. 

This new development will set off a wave of litigation, with the Sioux tribe of Standing Rock promising to sue if the Corps doesn’t follow through with the promised environmental review. 

"We stand ready to fight this battle against corporate interest superseding government procedure and the health and wellbeing of millions of Americans,” they said in a statement. 

“This action will serve facilitate completion of the last mile and a half of the 1,172 mile pipeline, connecting the Bakken and Three Forks oil production areas in North Dakota to an existing crude oil terminal near Pakota, Illinois," Robert Speer, the acting secretary of the Army, said in a statement. 

Speer indicated that there was enough available data to support granting the necessary easement; or in other words, there is no longer any need for an Environmental Impact Statement. 

Protesters are gearing up for the latest chapter in the battle as veterans groups make plans to return to Standing Rock and support them.

A storm system that included as many as six tornadoes churned through southeastern Louisiana on Tuesday, injuring about 40 people. 

<a href="http://www.earth.com/news/gulf-waters-eating-away-at-small-towns-outside-of-new-orleans-levees-2/">New Orleans</a> East was hit particularly hard by the storms – quite a blow to an area that was previously devastated by Hurricane Katrina in 2005. About 20 people were hurt there when an EF2-strength tornado touched down, tearing roofs off of houses and sending the New Orleans Police Department scrambling to assist with emergency response efforts.

The storm damaged <a href="https://www.nasa.gov/">NASA</a>’s Michoud Assembly Facility and the <a href="https://www.usda.gov/">USDA</a>’s National Finance Center’s Primary Business Center. There were only minor injuries among the people in those buildings. 

Brittany Ross lived in a trailer park in eastern New Orleans. When the storm hit, her trailer “started shaking, kind of twisting,” she told the <a href="https://www.ap.org/en-us/">Associated Press</a>. The wind lifted her home up before slamming it back down again. She and two others were able to crawl from the remains of the trailer and escape to safety. 

The six tornadoes prompted Louisiana governor John Bel Edwards to take an aerial tour of the damage. He also declared a state of disaster in order to provide relief to those affected. 

The storms also swept through Baton Rouge, damaging structures and causing minor injuries. Several homes were destroyed in Killian, a town just east of Baton Rouge. There, an elderly couple were injured, with one suffering a broken arm and the other one a broken leg. The town’s mayor, Craig McGehee, was amazed the couple survived.

“How you manage to get blown completely across the street with cinderblocks flying and no worse than a couple broken limbs — apparently the good Lord was looking after them,” he said. 

Quarter-sized hail fell in Little Rock Arkansas and high winds and waterspouts plagued the coast of northwest Florida as the storm moved eastward. Wind gusts up to 62 miles per hour were reported in Henning, Tennessee.

The bald eagle has been the U.S. national emblem for over 200 years, chosen because of its immense strength, majesty, and longevity. It’s understandable, then, that Americans become distressed at seeing one of these beautiful creatures harmed in any way. 

This was the case on Sunday when a photographer noticed a bald eagle with a leg hold trap attached to its foot.

Photographer Susan Boardman observed the bald eagle moving around on the ground in the woods in Bonneauville, Pennsylvania. She noticed that the bird seemed to be struggling before she saw the leg trap, which was attached to a long chain. Although it had trouble getting off the ground, the eagle managed to fly away, trap in tow. 

Leg hold traps are used to catch fur-bearing animals such as foxes, <a href="http://www.earth.com/news/grizzly-bear-wolves-dinner/">wolves</a>, raccoons, and bobcats. They are supposed to be placed in such a manner that the bait isn’t visible from the air. 

Wildlife rehabilitators and bird-welfare volunteers have sounded the alarm and are on the lookout for the unfortunate bird. Large birds of prey can be dangerous to people who aren’t trained in handling them, so experts urge caution to anyone who may spot the eagle. 

“There’s really not much the average person can do,” wildlife rehabilitator Wendy Ebersole told the<a href="http://www.yorkdispatch.com"> York Dispatch</a>. “Obviously, no one should try to handle the bird.”

She worries that if the bird can’t be located and the trap removed in a timely manner, the bird won’t survive. Eagles need the use of their talons in order to catch food, eat, and defend themselves from predators, she said.  

Boardman agrees. In an e-mail to the <a href="https://www.ap.org/en-us/">Associated Press</a>, she said, "Without intervention, this eagle will probably die. He can't hunt or fly high enough to get out of harm's way. It was heartbreaking to see him like this.”

While everyone was at home watching TV on Friday night, the U.S. and Japan were shooting down a missile in space. Relax – no one was under attack. The joint effort was part of a missile block test for a $3.2 billion defense system designed to shoot down ballistic missiles. 

The test, carried out at around 10:30 p.m. off the coast of Kauai in Hawaii, was a success. The Aegis Missile Defense System and Standard Missile-3 Block IIA interceptor installed onboard the USS John Paul Jones was able to track, locate, and shoot down a ballistic missile, according to the<a href="https://www.mda.mil"> U.S. Missile Defense Agency</a> (MDA).

Friday’s test marked the third flight test of the SM-3 Block IIA guided missile. However, it was the first intercept test, as well as the first time such a missile was launched from an Aegis ship. The U.S. Navy also said this is the first intercept engagement using the Aegis Baseline 9.C2 (BMC 5.1) weapon system.

The U.S. and Japan have cooperated since 2006 on development of the Standard Missile-3. The MDA reports that America has invested $2.2. billion on the system and Japan has spent approximately $1 billion. 

The missile block test took place as tensions have escalated over North Korea’s <a href="http://www.earth.com/news/new-nuclear-reactor-design/">nuclear</a> weapons cache. U.S. Defense Secretary Jim Mattis warned of an “effective and overwhelming” response should North Korea attack the U.S. or its allies. 

"Today's test demonstrates a critical milestone in the cooperative development of the SM-3 Block IIA missile," said MDA Director Vice Admiral  Jim Syring in a statement. 

”The missile, developed jointly by a Japanese and U.S. government and industry team, is vitally important to both our nations and will ultimately improve our ability to defend against increasing ballistic missile threats around the world.”

Nearly 252 <a href="http://www.earth.com/news/shattered-asteroid-millions-years-ago/">million </a>years ago, our planet experienced something scientists have deemed The Great Dying. What happened during the event isn’t any more cheerful than its name; the Earth lost up to 96% of its marine species, as well as nearly 70% of terrestrial vertebrates.

Why these species died out is a question that’s baffled scientists for years. A new study has added yet another theory to the mix: could waves have caused this kind of mass extinction? 

New evidence points to <a href="http://www.earth.com/news/app-helps-fishermen-sell/">shoaling</a> as a possible source of The Great Dying. Shoaling refers to the phenomenon that happens when waves grow taller as they reach shallow water while heading towards the shore. This causes changes in water density and velocity, stirring up the ocean floor. 

Researchers believe that when the ocean floor became churned up, it stirred up sulfides that made the water uninhabitable for many ocean species. They aren’t sure why there would have been such a sudden increase in shoaling. They do know that sulfide is toxic to animals in high concentrations.

They also know that the area around Pangea – a former supercontinent – had high levels of sulfide on the ocean’s floor. The team, which included Yanen Shen from the<a href="http://en.ustc.edu.cn"> University of Science and Technology of China</a>, studied rocks found in what was once the Panthalassic Ocean. They collected rocks from areas near Canada and Japan and noted a mixture of various types of sulfur. 

"The shoaling of sulphidic waters, therefore, would kill marine animals in the Permian-Triassic oceans," said Shen in a statement. The team believes that the sulfur may have caused the mass extinction, as well as the recovery process that took nearly 10 million years. 

"This study illustrates how environmental changes could have had a devastating effect on Earth's early biosphere, and may have present-day relevance because global warming and eutrophication are causing development of sulfidic zones on modern continental shelves, threatening indigenous marine life,” the study authors wrote. Their findings were published in the journal<a href="http://www.pnas.org"> PNAS</a>.

Cosmic rays sounds like something out of a Ziggy-Stardust-era David Bowie song, but they’re real. It also turns out that these radiation clouds that appear at high altitudes may be problematic for frequent airline travelers. 

Scientists have always known that people were exposed to some degree of radiation when they traveled by airplane. Things like cosmic rays and solar wind sometimes penetrate the magnetic field around the Earth, creating low levels of <a href="http://www.earth.com/news/fukushima-radiation-levels-high/">radiation</a> through which air passengers soar when they fly. Levels of this radiation are higher in the polar regions, and longer flights subject passengers and crew to more radiation than shorter ones. 

How much radiation are we talking, here? Experts previously estimated that it would take a flight of approximately 12.5 hours to deliver as much radiation as a chest X-ray. That’s if the flight stays in the high latitudes and isn’t zipping past the polar regions or traveling when there are solar storms.

Meanwhile, they reported that mid-latitude flights take around 25 hours and flights around the equator take 100 hours to deliver the same amount of radiation.

New research has revealed that the levels in radiation clouds may be higher than scientists once thought, however.

W. Kent Tobiska and his team from<a href="http://www.spacewx.com"> Space Environment Technologies</a> ran tests that found surges in radiation level data that spiked as high as double what they had previously expected. He believes that radiation particle belts trapped in Earth’s magnetic field may sometimes “leak” and move into the Earth’s stratosphere. Flying through these particle clouds could cause the kinds of spikes seen in the research. 

If Tobiska’s theory is confirmed, scientists will need to find a way to identify the location of such clouds so that air crews can avoid them during flights. The team’s findings were published in the journal <a href="http://agupubs.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1542-7390/">Space Weather</a>.

A leading association of hemp advocates is suing the<a href="https://www.dea.gov/index.shtml"> Drug Enforcement Administration</a> (DEA) over claims that the agency violated a court order when it started cracking down on products made with hemp in letters sent out last December.

For decades, cannabis has been illegal under U.S. federal law. However, regulation of cannabis has also lead to a crackdown on hemp, its non-psychoactive cousin. While the form of cannabis we traditionally know as marijuana has high (no pun intended) amounts of THC, industrial hemp has amounts of less than 0.3%. In other words, you could smoke a truckload of hemp and not get high.

Despite this, products like hemp seed and hemp seed oil remained illegal for years in the U.S. In 2004, the<a href="https://www.thehia.org"> Hemp Industries Association</a> (HIA) sued the DEA in a case that became known as the “Food Rules Challenge.” The Ninth Circuit Court of Appeals sided with the HIA, ruling that hemp does not belong on the list of Schedule I controlled substances. In 2014, Congress passed a Farm Bill that gave permission for states to grow hemp under a special licensing program. 

Late last year, the DEA struck again, this time working with the<a href="https://www.nd.gov/ndda/"> North Dakota Department of Agriculture</a> (NDDA) to send correspondence to<a href="https://www.healthyoilseeds.com"> Healthy Oilseeds, LLC</a>. The company was informed that in order to ship their hemp protein powder and hemp seed oil products, they’d have to get a permit from the DEA.  

The HIA is fighting back, claiming that the DEA has overstepped its bounds, violating the intent of the Farm Bill, as well as the Consolidated Appropriations Act of 2016, which prevents authorities from using funds to stop the “transportation, processing, sale, or use of industrial hemp.” They have filed a Petition for Review with the Ninth Circuit Court of Appeals.

“It is disappointing that the industry has to revisit the issue, and take this step to compel DEA to obey the law,” said Joe Sandler, HIA’s lead counsel.

<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.
