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.

Bogus global warming data at the center of new debate. A whistleblower from the<a href="http://www.noaa.gov"> National Oceanic and Atmospheric Administration</a> (NOAA) has released evidence claiming that the organization used manipulated data to influence world leaders ahead of the 2015 UN climate conference in Paris.

The paper released by NOAA denied any supposed “pause” in global warming since 1998 and instead reported that world temperatures had been rising at an unanticipated rate. 

It likely influenced top policymakers such as President Barack Obama and UK Prime Minister David Cameron when they met in Paris for the conference that year. There, world leaders came together to work on an agreement for their nations to cut back on the use of fossil fuel in an effort to prevent further warming. 

Both sets of data used to compile the report were flawed. One set focused on temperature measurements from the Earth’s surface, while the other measured the temperature at the surface of the seas. The latter set is so flawed that NOAA is calling for it to be replaced because it used unreliable methods that overstate temperatures levels and how quickly they are rising.

This information came to light when John Bates, a top scientist at NOAA, gave an exclusive interview to the<a href="http://www.dailymail.co.uk/ushome/index.html"> Daily Mail</a>. He objected to the publication of the Pausebuster paper, a report that he said was never subjected to NOAA’s typically-rigorous internal evaluation process. 

Bates accused Thomas Karl, the lead author of the paper, of “insisting on decisions and scientific choices that maximized warming and minimized documentation… in an effort to discredit the notion of a global warming pause.” Bates said Karl “rushed so that he could time publication to influence national and international deliberations on climate policy.”

For his part, Karl denies that the intention of publishing the Pausebuster data without putting it through further review was to influence lawmakers about to convene for the climate conference. “There was no discussion about Paris,” he said.

This scandal is sure to add fuel to the fire of the heated debate over the science behind climate change.

World leaders swayed by bogus global warming data

When a <a href="http://www.earth.com/news/new-nuclear-reactor-design/">nuclear</a> catastrophe happens, scientists rely on robotic probes to give them an insider’s view of conditions at the site. Such is the case at Japan’s Fukushima nuclear plant. However, radiation levels are currently so high at the plant that even robotic welfare is being put in jeopardy. Why? They’ll melt. 

On March 11, 2001, a tsunami developed after an undersea earthquake shook the area off the coast of Fukushima. The giant wave killed more than 18,000 people and wiped out the nuclear plant there, sending three reactors into meltdown.

Since then, the Japanese government has worked hard to clear up the site, a process that it expects to cost as much as $190 billion and span decades. Part of the reason the cleanup is moving so slowly is the high radiation levels around the site.

Until recently, scientists at the Tokyo Electric Power Co (TEPCO) used radiation-resistant robot probes with attached cameras to wander through reactors and monitor conditions. The robots are about two feet long and small enough to move through a 4-inch-wide pipe that leads into the reactor’s containment vessel.

Radiation levels are measured in seiverts per hour. Robot probes are made to withstand exposure levels up to 530 sieverts per hour – and levels inside one of the reactors have just hit that critical threshold. Robots sent in to operate at that exposure level will shut down within a mere two hours. 

Thankfully, TEPCO reports that the radiation is confined within the reactor and there are no leaks. They say that the high radiation levels are likely confined to a single point. This means that if a robot is moving around, it can likely continue to operate within the reactor – providing real hope for a continued monitoring and recovery process.

Imagine living where the air pollution levels are so high that dead birds drop out of the sky and fall to the ground around you, or where the simple act of breathing in and out carries the same health risk as smoking two packs of cigarettes a day. That’s what people in Mexico City have experienced for decades, leading city officials to test programs to improve air quality.

First, they restricted driving on a couple of days during the week. It didn’t do much to affect pollution levels. The latest step in their bid for cleaner air extended the driving restrictions to include Saturdays.

The restriction program functions based on vehicle license plate numbers. Plates ending in certain numbers can’t be driven on certain days of the week between 5 a.m. and 10 p.m. The ban applies both to personal and commercial vehicles. 

However, the driving restrictions aren’t producing results. According to a study published in the journal<a href="http://www.nature.com/srep/"> Scientific Reports</a>, air pollution levels in Mexico City aren’t dropping. Scientists looked at data from 29 air pollution monitoring stations positioned around the city. Data collected from 2005 to 2012 indicated that emission levels of carbon monoxide, nitric oxide, nitrogen dioxide, nitrogen oxide, ozone, large and small particulates, as well as sulfur dioxide did not reduce after implementation of the driving restrictions.

<a href="http://www.berkeley.edu">University of California Berkeley</a> Associate Professor Lucas W. Davis found no indication of an increased number of people using public transportation, making him think that people are purchasing multiple vehicles or using services like Uber to get around driving restrictions.

“Saturday driving restrictions are a flawed policy,” he said. “It's a big hassle for people and does not improve air quality.”

Whenever the <a href="http://www.earth.com/news/california-rainstorms-instagram/">weather</a> gets crazy, meteorologists always seem to blame it on El Niño. Drenching floods? El Niño, of course. Winter tornadoes? That darned El Niño! Mid-December heatwave? You can’t show off your ugly Christmas sweater when El Niño keeps messing with the weather! 

The target of our weather-related wrath, El Niño, is a phenomenon that occurs in the equatorial Pacific region. It’s part of the larger El Niño-Southern Oscillation (ENSO), and scientists say that ENSO’s behavior is becoming increasingly difficult to predict. 

The news comes from Fei Zheng of the <a href="http://english.iap.cas.cn">Institute of Atmospheric Physics</a>. "The forecasting reliability during the period 2002-2011 was relatively lower than that in the 1980s and 1990s,” he said. His team went to work to find out why. 

Their study, published in the journal <a href="http://agupubs.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1944-8007/">Geophysical Research Letters</a>, looked at 20 state-of-the-art weather models and analyzed their prediction skills. They found that the Bjerknes Feedback (BF) intensity is the best factor through which to monitor ENSO and determine its predictability. 

Why has the BF intensity varied so much over the past 10 years? Scientists say it’s because of sensitivity of the zonal winds to zonal sea level pressure (SLP) gradient in the area. Anomalies in zonal wind in the equatorial Pacific can cause SLP variations, which can then transfer to surface temperature and precipitation fields via the BF. 

What does all this mean? Zheng suggests a change in the specific factors that scientists monitor closely when watching ENSO. Going forward, he says, “"More attention should be paid to off-equatorial processes in the prediction of ENSO during the low-ENSO predictability period."

Perhaps this will give the rest of us a better idea of when to eschew a sweater for a pair of flip flops – or buy an inflatable raft.

There could be an entire lost world just under your feet. That’s what scientists found under the white-sand island of Mauritius – a piece of a lost continent from approximately 200 million years ago. 

They believe that the fragment of crust was a piece of Mauritia, an ancient lost continent that once sat between Madagascar and <a href="http://www.earth.com/news/air-pollution-crisis-india/">India</a>. Mauritia formed when the supercontinent Gondawa broke into pieces. 

“Mauritia acted as a buffer zone between the western Indian subcontinent and eastern Madagascar, and was fragmented by numerous tectonic and volcanic events that occurred in that region since the early Cretaceous,” wrote the authors of the study. 

Scientists, including Lewis Ashwal from <a href="https://www.wits.ac.za">Wits University</a>, discovered the “lost continent” in the form of zirconium crystals that are between 2.5 billion and three billion years old. The material, which had been covered by lava from volcanic eruptions on Mauritius, was discovered in an outcropping of tracheae rocks. 

How do they know their finding is a part of a continent rather than just an extremely old piece of rock? 

"Earth is made up of two parts - continents, which are old, and oceans, which are ‘young,’” Ashwal explained. “On the continents you find rocks that are over four billion years old, but you find nothing like that in the oceans, as this is where new rocks are formed. Mauritius is an island, and there is no rock older than 9 million years old on the island.” 

“However, by studying the rocks on the island, we have found zircons that are as old as 3 billion years,” he said. 

The authors of the study wonder if other continental fragments may be hidden beneath layers of lava. 

“Evidence is accumulating that old continental crust may occur beneath some young ocean-island volcanoes, contributing contaminating components to their chemical and isotopic compositions,” they wrote. 

Ashwal and his colleagues published their findings in the journal <a href="http://www.nature.com/ncomms/">Nature Communications</a>.

Congressional Republicans have introduced a bill that would sell off a chunk of American public land the size of Connecticut. House Bill 621, introduced by<a href="http://chaffetz.house.gov"> Jason Chaffetz</a> of Utah, proposes the sale of 3.3 million acres of land that’s currently maintained by the <a href="https://www.blm.gov">Bureau of Land Management</a>.

While BLM land is leased out for oil, gas, and timber production, it’s also used by the public for camping, hiking, and mountain biking. It’s popular among fisherman, hunters, and other outdoorsmen. 

Apart from human industry and enjoyment, BLM land gives essential cover to animals such as gray wolves and <a href="http://www.earth.com/news/grizzly-bear-wolves-dinner/">grizzly bears</a>. Big game such as elk and big-horned sheep use low-lying BLM land as a grazing spot during the winter months when the mountains are covered in snow.

The public land being targeted for “disposal” is spread across ten states, including Arizona, Colorado, Idaho, Montana, Nebraska, Nevada, New Mexico, Oregon, Utah, and Wyoming. <a href="https://chaffetz.house.gov/sites/chaffetz.house.gov/files/land%20disposal%20report.pdf">Representative Chaffetz’s website</a> features a chart that maps out the lands that will be affected. 

The land potentially being offloaded was first identified in a 1997 survey by the Clinton Administration. Their goal was to offset $7.8 billion in aid being offered to the Florida Everglades, which had been heavily damaged by polluted runoff from the sugarcane industry. However, the survey warned that the lands being considered may not be ideal for disposal due to cultural significance, as well as the existence of endangered species.  

In addition to the overall loss of land, outdoor enthusiasts worry that the sale of certain swaths of land could cut off access to other publicly-owned areas. This happened in <a href="https://www.fs.usda.gov/coronado/">Coronado National Forest</a>, where the sale of a ten-acre parcel cut off public access to hundreds of thousands of acres.   

“Last I checked, hunters and fishermen were taxpayers,” said New Mexico resident Jason Amaro to <a href="https://www.theguardian.com/">The Guardian</a>. As the representative of the southwest chapter of <a href="http://www.backcountryhunters.org">Backcountry Hunters and Anglers</a>, Amaro is upset that his state will potentially lose 800,000 acres of BLM land. 

“That word ‘disposal’ is scary,” Amaro said. “It’s not ‘disposable’ for an outdoorsman.”

<a href="http://www.earth.com/news/epa-volkswagen-intentionally-violates-clean-air-act/">Volkswagen</a> owners were left fuming a few years ago when they discovered that the car manufacturer had fitted emissions-cheating software to many of its diesel vehicles. They sued Volkswagen and auto supplier <a href="http://www.bosch.us/content/language1/html/2274.htm">Robert Bosch</a>, and now the defendants have reached a Dieselgate settlement and have agreed to pay out $1.22 billion and $327.5 million, respectively. 

The PR nightmare for Volkswagen began when it was discovered that for ten years, they had knowingly installed a “defeat device” that skewed its vehicles’ emissions readings whenever they were being tested. This came as the car company was proudly promoting the low emission levels of its lineup.

Volkswagen first tried to write the discovery off as testing “irregularities” before finally admitting that it installed improper software in more than 11 million of its vehicles. 

In the settlement, Volkswagen agrees to fix or buy back approximately 80,000 3.0 liter diesel-engine vehicles sold in the U.S. It’s faced with a potential payout of $4.04 billion if regulators don’t approve their bid to fix the vehicles affected. 

The settlement – which must be approved by a judge before moving forward – will compensate owners of 3.0 liter vehicles between $7,000 and $16,000 to fix their vehicles. If the fix affects a vehicle’s performance, VW will pay an additional $500. 

Meanwhile, the Bosch payout will pay $163.3 million to 2.0 liter vehicle owners and $113.3 million to 3.0 liter owners. Owners of 2.0 liter vehicles will receive $350 each, and individuals who own a 3.0 liter will each receive $1,500. 

Bosch denies any liability or wrongdoing in the scandal now known as “Dieselgate,” but it says that it settled in order to focus on the “transformation process” the company is now experiencing. 

The lead lawyer for the plaintiffs, Elizabeth Cabraser, said that the Dieselgate settlement will result in "substantial benefits to both consumers and the environment."

Oldest human ancestor revealed. When you look through <a href="http://www.earth.com/news/chimps-family-opposites-attract/">family</a> photos, it’s often easy to see where you got your blue eyes or turned-up nose. It may come as a surprise, then, that none of us resemble the creature that scientists are calling our oldest human ancestor.

Known as Saccorhytus, traces of the <a href="http://www.earth.com/video/french-bulldogs-craze/">animal</a> were found preserved as a 540-million-year-old fossil. Despite its age, scientists said the fossil was “exquisitely well-preserved.” The tiny being was only about a millimeter in size – so small that it lived between grains of sand at the bottom of the sea. 

<a href="https://www.cam.ac.uk">University of Cambridge</a> professor Conway Morris, who led the research team, spoke to<a href="http://www.bbc.com/news"> BBC News</a> about their discovery. “To the naked eye, the fossils we studied look like tiny black grains,” he said, “but under the microscope the level of detail was jaw-dropping.” Their findings were published in the journal<a href="http://www.nature.com/nature/journal/vaop/ncurrent/full/nature21072.html"> Nature</a>. 

While it may seem odd that our earliest <a href="http://www.earth.com/video/oldest-human-ancestor-found/">ancestor</a> is a minuscule sea creature, Saccorhytus was one of the steps in the evolutionary process that created fish, as well as humans. It belongs to a category of animals called “deuterostomes.”  This group includes animals such as sea cucumbers and urchins. Its name, which means “second mouth,” refers to a developmental process in which the anal opening develops before the mouth. (Too much information? Let’s move on.) In short, vertebrates are all deuterostomes. 

Despite its being a deuterostome ancestor, scientists can only find an oral opening on Saccorhytus. “Our material is generally crushed, and despite the superb preservation we might have overlooked the evidence,” Morris said to the<a href="https://www.nytimes.com"> New York Times</a>. 

If, in fact, there isn’t an additional opening, researchers believe that the creature ate and excreted waste through the one orifice. (Still too much info. Right.) 

Saccorhytus had a symmetrical body and seems to have moved by contracting its muscles and wriggling around. Scientists also note that it had tiny conical structures that were possibly an early form of gills.

Most noteworthy, though? Its large mouth, which it used to suck in food particles before digesting them and…  Well, you know.

In 1972, the World Heritage Convention designated certain cultural and natural sites as places of “outstanding universal value.” These sites – including the <a href="http://www.greatbarrierreef.org">Great Barrier Reef</a> in Australia, the<a href="http://whc.unesco.org/en/list/81"> Chartres Cathedral</a> in France, and <a href="https://www.nps.gov/yose/index.htm">Yosemite National Park</a> in the U.S. were labeled as World Heritage Sites. <a href="http://en.unesco.org">UNESCO</a>, the educational, scientific, and cultural branch of the <a href="http://www.un.org/en/index.html">United Nations</a>, legally recognizes these sites, plus they’re protected by international treaties.

Treaties notwithstanding, these sites are still threatened by <a href="http://www.earth.com/news/water-maps-show-human-activity/">human activity</a>.  A new study warns that over 100 World Heritage sites are being damaged and altered by things like road construction, urbanization, agriculture, and industrial infrastructure. Deforestation has also devastated many of these natural sites. 

The research effort was led by researchers from the <a href="http://www.unbc.ca">University of Northern British Columbia</a>, the<a href="https://www.iucn.org"> International Union for Conservation of Nature</a> (IUCN), the <a href="https://www.wcs.org">Wildlife Conservation Society</a> (WCS), and the <a href="http://www.uq.edu.au">University of Queensland</a>. Published in the journal <a href="https://www.journals.elsevier.com/biological-conservation/">Biological Conservation</a>, the study revealed that over the past 20 years, the human footprint has grown by 63% in Natural World Heritage Sites in every continent except Europe. 

The sites that suffered the worst impact were India’s <a href="http://whc.unesco.org/en/list/338">Manas Wildlife Sanctuary</a>,<a href="http://whc.unesco.org/en/list/9"> Simien National Park</a> in Ethiopia, and Nepal’s <a href="http://www.chitwannationalpark.gov.np">Chitwan National Park</a>. Other sites suffered extreme deforestation. For instance, the <a href="http://whc.unesco.org/en/list/196">Río Plátano Biosphere Reserve</a> in Honduras has lost 8.5% of its forest since 2000. North American parks were also sites of extreme forest loss. <a href="https://www.nps.gov/yell/index.htm">Yellowstone National Park</a> in the U.S. lost 6% of its forests and <a href="http://www.pc.gc.ca/eng/pn-np/ab/waterton/natcul/inter.aspx">Waterton Glacier International Peace Park</a>, which spans across the U.S. and Canada, lost 23%. 

James Watson of the University of Queensland and WCS is the senior author of the study, which appeared in the journal Biological Conservation. He said, "Any place that is listed as a World Heritage site is a globally important asset to all of humanity. The world would never accept the<a href="http://www.acropolisofathens.gr/aoa/"> Acropolis</a> being knocked down, or a couple of pyramids being flattened for housing estates or roads, yet right now, across our planet, we are simply letting many of our natural World Heritage sites be severely altered."

When we think of <a href="http://www.earth.com/video/artificial-ice-storms-severe-weather/">weather reports</a>, we tend to visualize our friendly local meteorologist, gesturing and pointing to colorful weather maps displayed on our TV screens. “Thunderstorms tomorrow – don’t forget your umbrellas!” But the public now has access to a new frontier in weather science, however: that of space weather. 

What is space weather and why does it matter? We aren’t talking gentle rain showers and sunny days, here. Think of radiation put out by solar flares, high-speed solar winds, or explosions of plasma from the sun’s surface and you’ll get an idea of what space weather involves. 

The kind of events that happen way up in space can affect quite a bit down here on Earth, scientists say. From satellites and aircraft to our communication, navigation, and power systems, space weather can impact humans in a multitude of ways. For instance, radiation released from a solar flare could require that a flight following a polar route be diverted. Our electric power grid can be shut down by solar winds, as well as magnetic and plasma bursts from the sun. 

Space weather also causes a threat to satellites. Radioactive particles can damage individual satellites, causing a communication failure. The problem grows larger, however, if that satellite drifts into the path of others, damaging them and creating a system shutdown. 

More than 16 years’ worth of data on space weather will now be publicly available, enabling scientists to better predict when events will occur that may disrupt satellites, as well as earthbound equipment. The data has been collected by Los Alamos GPS sensors that “have been fielded on GPS satellites for decades,” says<a href="http://www.lanl.gov"> Los Alamos National Laboratory</a> program manager Mark Kippen.  The data is hosted by the<a href="http://www.noaa.gov/"> National Oceanic and Atmospheric Administration</a> (NOAA), and a feature article about the data release was published in the journal<a href="http://agupubs.onlinelibrary.wiley.com/hub/journal/10.1002/(ISSN)1542-7390/"> Space Weather</a>.

While California’s long <a href="http://www.earth.com/image/southern-california-drought-continues/">drought</a> isn’t over, a pair of rainstorms that ripped down the West Coast may have gone a long way towards repairing the water shortage. Scientists believe powerful storms that swept California from December through January have likely refilled a whopping 37% of California’s snow-water deficit.

The team from the <a href="http://www.colorado.edu">University of Colorado</a> at Boulder analyzed rainfall totals from two recent storms over the Sierra Nevada region. The storms dropped nearly 17.5-million acre feet, or 21.6 cubic kilometers of water on the mountain range. 

Scientists determined this amount by looking at data from NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS), a device located on NASA’s Aqua and Terra satellites. They also looked at a computer model drawn up by the University of Colorado and the Jet Propulsion Laboratory at <a href="https://www.nasa.gov/">NASA</a>, as well as data from <a href="http://www.water.ca.gov/">California Department of Water Resources</a> snow sensors. 

These numbers are noteworthy because they total more than 120% of the average snow accumulation for the area in the pre-drought time before 2012. From 2012 to 2016, California began experiencing an average annual snow-water deficit of nearly 10.8 million acre feet (13.3 cubic kilometers). This added up to 54 million acre feet (67 cubic kilometers) over that period. 

The storms that dumped large amounts of rain over California this winter are known as “atmospheric rivers.” These send huge amounts of moisture from the tropics to the west coast of the U.S., resulting in heavy rain and snowstorms. The Pineapple Express is an example of one of these atmospheric rivers. 

Although the new numbers are promising, Noah Molotch, leader of the study, says that one rainy winter season won’t be enough to make up its water deficit. 

"When the snow stopped falling five years ago, the state had to tap into its groundwater reserves to keep up," he said. "One snowy winter won’t be able to entirely reverse that, but there is, at least, some cautious optimism.”

Powerful storms pump up California’s snow-water deficit by 37%

In the past week, President Donald Trump has instituted a media blackout on federal agencies like the<a href="http://www.epa.gov"> EPA</a>,<a href="https://www.usda.gov/"> USDA</a>, and the<a href="https://www.doi.gov"> Department of the Interior</a>. The agencies were instructed to cease all communication via press releases and social media posts. This move alarmed many federal employees who were concerned that information released going forward would be carefully filtered to support the new administration’s political agenda. But concerned employees aren’t going gentle into the darkness of a media blackout and instead have found a useful new tool: rogue social media accounts.

The first warning shot was fired from someone with access to the Twitter account belonging to<a href="https://www.nps.gov/badl/index.htm"> Badlands National Park</a>. On Tuesday, they posted several messages about <a href="http://www.earth.com/news/attribution-science-extreme-weather-events/">climate change</a>. A spokesperson from the Park Service said that the posts were from a former employee who was not authorized to use the account.

Next: a new and ingenious strategy in the resistance to the gag on these organizations. Rogue social media accounts appeared with the purpose of distributing information that can no longer be put out via official channels. An<a href="https://twitter.com/AltNatParkSer"> AltUSNatParkService</a> Twitter account appeared, followed by a slew of other accounts including<a href="https://twitter.com/AltForestServ"> AltUSForestService</a> and<a href="https://twitter.com/RogueNASA"> Rogue NASA</a>.

At first, these accounts claimed to be run by anonymous federal employees. Many of them have since shifted gears and say they are run by non-government activists.

Whatever the truth may be, the accounts all have the same goal – posting and promoting scientific research, facts, and information that has mysteriously disappeared from agency websites since Trump took office. Some of the accounts, such as BadHombreLands NPS, are using their social media presence for calls to action against legislation that threatens public lands. 

What will become of these accounts remains to be seen, but it’s clear that social media will be a useful tool in the growing scientific resistance to the Trump agenda.

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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.

Wildlife tunnels save millions of amphibians

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.

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.
