For something you can’t see with the naked eye, algae sure know how to shake things up. Around 14,000 years ago, microscopic Antarctic algae helped slow down global warming by pulling huge amounts of carbon dioxide out of the atmosphere.



Scientists just figured out how they did it - and why the same process that once helped cool the planet could play a critical role in shaping the future of our climate.



<h2 class="wp-block-heading" id="h-antarctic-algae-changed-the-climate">Antarctic Algae changed the climate</h2>



Back then, Earth was gradually warming after the <a href="https://www.earth.com/news/disastrous-climate-changes-of-the-last-ice-age-could-happen-again/">last ice age</a>. However, something unusual occurred in the Southern Hemisphere: the warming paused. 



This period, referred to as the <a href="https://www.earth.com/news/rising-co2-will-cause-rapid-climate-change-in-the-tropical-andes/">Antarctic Cold Reversal</a>, was a time when sea ice expanded quickly in winter and melted quickly in spring. That spring melt converted the Southern Ocean into a super buffet for a particular type of algae, Phaeocystis.



These tiny ocean plants went wild. They multiplied, and in doing so, they pulled vast quantities of carbon dioxide - one of the primary drivers of global warming - out of the atmosphere and stored it away in the sea.



Here’s the twist: until now, we had no idea <a href="https://www.earth.com/news/sea-ice-loss-alters-the-color-of-ocean-light-and-life-struggles-to-adapt/">Phaeocystis</a> even played a role. Scientists couldn’t find any trace of them in the usual fossil records. 



Now, thanks to a new method that recovers ancient DNA from the ocean floor, researchers from the Alfred Wegener Institute in Germany have filled in this crucial missing piece of the climate puzzle.



<h2 class="wp-block-heading" id="h-unlocking-antarctica-s-hidden-record">Unlocking Antarctica’s hidden record</h2>



The team studied a sediment core taken from nearly 2,000 feet deep in the Bransfield Strait, just off the Antarctic Peninsula. Layer by layer, this core preserves snapshots of ocean history going back 14,000 years.



By analyzing the ancient DNA trapped in that sediment, the scientists found genetic fingerprints of Phaeocystis during the cold reversal period. No one had ever identified these algae in the past using standard geochemical methods.



“Our study shows that these algal blooms contributed to a significant reduction in global atmospheric CO2 levels during a climatically important transition phase characterized by high sea ice extent,” said Josefine Friederike Weiß from the <a href="https://www.awi.de/en/" target="_blank" rel="noreferrer noopener">Alfred Wegener Institute</a>, lead author of the study.



They also measured something else: a high ratio of barium to iron in the sediment. That ratio is tied to how much organic material - like dead algae - sinks to the seafloor. In this case, the data pointed to intense algal growth during times of heavy spring melt.



“The further the sea ice expands in winter, the larger the area in spring where nutrient-rich meltwater enters the surface sea - and therefore the zone where Phaeocystis algae find ideal growth conditions. As a result, greater sea ice extent leads directly to a larger region with high algal productivity.”



<h2 class="wp-block-heading" id="h-why-today-s-melting-ice-is-a-warning">Why today’s melting ice is a warning</h2>



The same Phaeocystis algae that once helped cool the world are now struggling to survive. With <a href="https://www.earth.com/news/rapid-antarctic-sea-ice-loss-is-causing-severe-storms-around-the-world/">Antarctic sea ice</a> declining at a record rate, the conditions that previously drove these algae blooms are vanishing.



That’s not just bad news for the algae. These blooms power entire food webs. They feed tiny animals, which feed fish, which in turn feed everything from squid to seals. If Phaeocystis disappears, the whole system could unravel.



Even worse, these algae are really good at one specific job: getting <a href="https://www.earth.com/news/how-the-ocean-holds-carbon-hidden-mechanisms-revealed/">carbon</a> to sink deep into the ocean. Losing them could mean more carbon sticks around in the atmosphere, heating the planet faster.



And there’s another concern. Phaeocystis releases a gas called dimethyl sulfide (DMS), which helps form clouds. More clouds mean more sunlight bounces back into space. Fewer algae mean fewer clouds. That’s one more way climate change could end up feeding on itself.



<h2 class="wp-block-heading" id="h-antarctic-algae-holds-future-lessons">Antarctic algae holds future lessons</h2>



The study shows why scientists must look beyond conventional methods. By combining geological tools with DNA analysis, researchers are creating a more accurate picture of how the ocean shapes our climate - and how it might respond in the future.



The research also highlights a larger trend in climate science. For years, scientists focused mainly on ice cores and chemical markers.



Now, by analyzing the genetic material of ancient microbes, we can see what species were doing during pivotal climate events - and what those behaviors could mean for us today.



This is important because forecasting future climate change isn’t only about tracking temperature or carbon levels. It’s about understanding the living systems that help regulate them - such as the algae and the seas they inhabit.



The full study was published in the journal <a href="https://www.nature.com/articles/s41561-025-01761-w" target="_blank" rel="noreferrer noopener">Nature Geoscience</a>.

Antarctic algae that once cooled Earth are now disappearing

US Coal Industry Facing New Hurdles. Beset by power plant closures, growing regulatory scrutiny and proposed changes in how they pay royalties, coal mines are facing a new obstacle - a review of how coal extracted and burned will impact the air and global warming.
Under a series of rulings by U.S. judges in Denver over the last year, federal agencies that approve mining projects have been told to take into account coal's indirect environmental impact along with traditional concerns about mine dust and equipment emissions.
The immediate effects of the rulings appear limited to a single mine in northwestern Colorado that could lose its permit if a new environmental review isn't completed within four months. But industry representatives fear the rulings, if allowed to stand, could set an example for other judges to follow and eventually threaten the mines that make up the backbone of an industry already facing uncertainty.
Two of the rulings involving Colorado mines, from U.S. District Judge R. Brooke Jackson, say greenhouse gas emissions need to be considered in environmental reviews. A similar case threatens to block production at another mine, in the coal-rich Powder River Basin of Montana and Wyoming. Another federal judge also recently ruled that a mine on the Navajo Nation must consider the effects of burning coal before expanding.
The agency at issue in the two most recent cases, the Office of Surface Mining Reclamation and Enforcement, is part of the Interior Department and regulates the environmental effects of mining across the country. Office spokesman Chris Holmes said the agency is still reviewing the rulings and hasn't decided what do to next. But fighting them would put the Obama administration in an awkward position because of its efforts to cut emissions of carbon dioxide, the most prevalent greenhouse gas.
The cases focused on coal from federal leases, which account for about 40 percent of U.S. production, but could open the door to similar legal challenges across the industry.
In his most recent decision, issued May 8, Jackson said the surface mining office must redo an environmental review for a coal mining project that's been underway for nearly a decade in northwestern Colorado or he would yank the mine's permit. The Colowyo Mine says losing the permit would lead to job losses for some of its 220 miners.
Colowyo is one of two mines that provide most coal for Colorado's Craig Station power plant, which generates about 8 million tons of greenhouse gases annually, according to federal emissions data.
Jackson, an Obama appointee, said if the government "can predict how much coal will be produced, it can likewise attempt to predict the environmental effects of its combustion."
Coal industry representatives said mines already face delays in permitting and adding more review would make matters worse. Colorado Mining Association President Stuart Sanderson said calculating a mine's contribution to global warming is meaningless because it's dwarfed by unregulated emissions in the developing world.
"It's pushing the envelope of regulation that is not in the nation's interests," Sanderson said of the rulings.
But legal experts say the rulings reflect an emerging trend of linking fossil fuel extraction to climate change.
"The agencies could continue to act just as they have been, but the cost of what they're doing will be more public and clear," said Justin Pidot, an assistant professor at the University of Denver's Sturm College of Law.
While he doesn't think the Colowyo mine will be forced to close, Mark Squillace, director of the University of <a href="https://www.bing.com/search?q=colorado&amp;cvid=b9d5958107674495959982113eb91af4&amp;FORM=ANAB01&amp;PC=HCTS">Colorado's</a> Natural Resources Law Center, said the more thorough reviews could lead the government to deny coal mining meant for export.US Coal Industry Facing New Hurdles
"I think the government is going to have to give serious thought to whether they're going to allow that to go forward," he said.
Environmentalists say the rulings will help open up what they view as an industry-tilted process so the public can decide if burning coal is worth the cost.
"I think the more we learn and the more honest accounting we get from the federal government, the more we will decide we don't like it," said Jeremy Nichols of WildEarth Guardians, which sued to stop the mining in northwestern Colorado and also was part of lawsuits to block mine expansions in Somerset, Colorado, and Decker, <a href="http://www.earth.com/earthpedia-articles/montana-valley-and-foothill-grasslands/">Montana</a>. US Coal Industry Facing New Hurdles
In the Somerset case, Jackson stopped the expansion of Arch Coal, Inc.'s West Elk mine last year partly because the Bureau of Land Management considered but rejected calculating the impact of future greenhouse emissions.
In April, another Denver federal judge, John Kane, ruled that the surface mining office must consider the effects of burning coal at a northwestern New Mexico power plant before allowing an expansion of the Navajo Nation's Navajo Mine. Environmentalists there were mostly concerned with mercury pollution impacting fish in the San Juan River.
The Navajo Nation company that owns the mine has appealed Kane's ruling. The government did not appeal the West Elk ruling.
In the Montana case, WildEarth Guardians and the Northern Plains Resource Council sued to block the mining of more than 117 million tons of coal, which would extend the life of Cloud Peak Energy's 280-worker Spring Creek mine by 13 years.
The environmental groups have asked U.S. District Judge Susan Watters to halt mining until its environmental impacts are more thoroughly vetted.
Cloud Peak and Montana Attorney General Tim Fox have entered the case on the side of the Interior Department, which wants it dismissed. In a notice to Watters' court filed Wednesday, attorneys for Wildearth Guardians were quick to point out their victory in Colorado in support of their arguments against Spring Creek.

Arctic Drill Ships

Kayaktivists Hold 'Shell No' Protest In Seattle. Kayaktivists Hold 'Shell No' Protest In Seattle. Activists opposed to drilling for oil in the Arctic plan to launch a flotilla of kayaks and other boats on <a href="http://www.earth.com/news/wildfire-smoke-seattle-air-dangerous/">Seattle's</a> Elliott Bay on Saturday, two days after the arrival of a towering oil rig that is the centerpiece of Shell's Arctic drilling fleet.
The "Paddle in Seattle" - a daylong, family friendly festival in a West Seattle park and an on-the-water protest by "Shell No" kayaktivists - aims to continue the message sent as the Polar Pioneer drilling rig arrived: "Stand up for the climate and say no to Shell's drilling plans."
"This weekend is another opportunity for the people to demand that their voices be heard," Alli Harvey, Alaska representative for the Sierra Club's Our Wild America campaign, said in a statement Friday. "Science is as clear as day when it comes to drilling in the <a href="https://www.bing.com/search?q=arctic&amp;cvid=d1e3254b61324c84bc4ec61307943e4f&amp;FORM=ANAB01&amp;PC=HCTS">Arctic</a>: the only safe place for these dirty fuels is in the ground." Kayaktivists Hold 'Shell No' Protest In Seattle
The gathering, hosted by a coalition of groups, is expected to draw thousands both on land and in the water. At the center of the paddle protest will be the "People's Platform," a 4,000-square-foot barge powered by renewable energy, said Jonathon Berman with the Sierra Club.

Just a quarter-mile away from the Seacrest Marine Park sits the 400-foot long, 300-foot tall Polar Pioneer, the first of two oil drilling rigs that Royal Dutch Shell plans to use this summer as it explores for oil off Alaska's northern coast. The second rig, the Noble Discoverer, arrived at the Port of Everett last week and is slated join the Polar Pioneer at the Port of Seattle's Terminal 5 at a later date. Everett port spokeswoman Lisa Lefeber said on Friday that they expect the Noble Discoverer to be there for two to three weeks.
The Arctic holds about 30 percent of the world's undiscovered natural gas and 13 percent of its oil, according to Shell's website.
"This amounts to around 400 billion barrels of oil equivalent, 10 times the total oil and gas produced in the North Sea to date," Shell's site says. "Developing Arctic resources could be essential to securing energy supplies for the future, but it will mean balancing economic, environmental and social challenges."
The activists see it differently, however.
The protesters say it's critical that they take a stand "against dirty fossil fuel projects" and want to put themselves on the front lines in the battle for Arctic oil.

Canada Plans To Reduce Greenhouse Gas Emissions By 30 Percent. Canada announced Friday it plans to reduce its greenhouse gas emissions by 30 percent below 2005 levels by 2030 amid international efforts to create a new framework for addressing climate change.
Prime Minister Stephen Harper's Conservative government said it formally submitted its target to the United Nations Framework Convention on Climate Change ahead of the major climate change conference in Paris in December.
The U.S. has committed to a 26 percent to 28 percent cut by 2025 from 2005 levels. The EU has a target of 35 percent below 2005 levels by 2030. Japan is proposing to cut its greenhouse gas emissions by up to 26 percent by 2030. China, the world's largest emitter, has not officially filed its target yet, but China did set a target for the country's emissions to peak by 2030 in a joint climate announcement with the U.S. last November.
A new international framework replacing the 1997 Kyoto Protocol is to be discussed at the Paris conference. The anti-global warming treaty has been largely ineffective because only rich countries were required to limit their emissions. Poorer countries have been reluctant to make commitments in a new framework.
Harper pulled Canada out of the Kyoto <a href="http://www.earth.com/news/kyoto-protocol-report-card-100-percent-compliance/">Protocol</a> in 2011, saying the accord would not help solve the climate crisis. That dealt a blow to the treaty, which had not been formally renounced by any other country. The U.S. never signed up.
Canadian Environment Minister Leona Aglukkaq said the new target is fair and ambitious and reflects the country's economic circumstances. Aglukkaq said they would introduce new regulations on methane emissions produced by the oil and gas industry as well as for natural gas-fired power generation and for the chemical and nitrogen fertilizer industries. There was no mention of new regulations for Alberta's oil sands industry, Canada's fastest growing source of emissions.
Canada might also buy international credits to meet its targets. Canada could get deductions from its counted emissions by investing in environmentally friendly projects in other countries.
Elliot Diringer, executive vice president of the U.S.-based Center for Climate and Energy Solutions, said when measured against current emissions, Canada's target is roughly comparable to the U.S. and the EU targets.
"Given that Canada pulled out of the Kyoto Protocol and that it is not on track to meet its 2020 target, Canada will have to work very hard to persuade the international community that it can deliver on its 2030 target," Diriniger said. "It would require significant effort beyond business as usual to deliver that reduction."
Environmentalists have long criticized <a href="http://www.earth.com/image/the-fall-rhapsody-in-ottawa/">Canada</a> as being an outlier on efforts to curb climate change. Harper has called Canada an emerging energy superpower and has avoided doing anything to get in the way of that.
Canada has the world's third-largest oil reserves, with more than 170 billion barrels. Daily production is expected to more than double by 2025. Only Saudi Arabia and Venezuela have more reserves. But critics say the enormous amount of energy and water needed in the extraction process increases greenhouse gas emissions. Canada Plans To Reduce Greenhouse Gas Emissions By 30 Percent
Under the 2009 Copenhagen Accord, Canada vowed to cut emissions 17 percent below 2005 levels by 2020, but Environment Canada reported last month that the country's greenhouse gas emissions rose between 2012 and 2013 to 726 megatons. It was the fourth consecutive annual increase.
"What hopefully Paris produces is institutionalized peer pressure to hold countries accountable for their promises," Diriniger said.

What do you do when you have 30 million young salmon ready for their big journeys downstream, but drought and development have dried your riverbeds to sauna rocks? In California this year, you give the fish a ride.
State and federal wildlife agencies in California are deploying what they say is the biggest fish-lift in the state's history through this month, rolling out convoys of tanker trucks to transport a generation of hatchery salmon downstream to the San Francisco Bay. California is locked in its driest four-year stretch on record, making the river routes that the salmon normally take to the Pacific Ocean too warm and too shallow for them to survive.
"It's huge. This is a massive effort statewide on multiple systems," said Stafford Lehr, chief of fisheries for the California Department of Fish and Wildlife, which since February has been rolling out four to eight 35,000-gallon tanker trucks filled with baby salmon on their freeway-drive to freedom.
"We're going to unprecedented drought," Lehr said. "We're forced to extreme measures."
Drought and heavy use of water by farms and cities have devastated key native fish in California. Last year, for example, 95 percent of the state's winter-run of Chinook salmon died. The fish is vital for California's fishing industries and for the food chain of wildlife.
For the first time, all five big government hatcheries in California's Central Valley for fall-run Chinook California salmon - a species of concern under the federal Endangered Species Act - are going to truck their young, release-ready salmon down to the Bay, rather than release them into rivers to make the trip themselves.
And California's wild native fish should pack a sandwich and something to read; they'll be spending a lot of the summer on the road too.
"Bone dry. Bone dry," said fish biologist Don Portz of the U.S. Bureau of Reclamation, who is six years into an effort to restore the southernmost salmon stream in the U.S., the Central Valley's San Joaquin River.
Drought, a dam and heavy use of the river's water for irrigation have dried 60 miles of the San Joaquin. For the young salmon, whose life cycle for millions of years has involved travel from the river back and forth to the San Francisco Bay, that now means a 1 1/2-hour ride down California Highway 99 in a pickup-mounted fish tank.
"You give them that taxi ride down, they make it to the ocean, and come back" in a few years for trapping and a taxi ride back up to spawning grounds, Portz said.
The rolling fish rescues occurring up and down the West Coast haven't always gone smoothly. In January, Oregon authorities charged a trucker with drunken driving after he hit a pole and flipped 11,000 juvenile salmon out on the roadway, where they died.
For some of California's native fish, the rescue from drought often is by bucket, not truck.
Near the town of Lagunitas, in Northern California's Marin County, watershed biologist Preston Brown stood ankle-high in a coastal tributary, searching for endangered California coastal Coho salmon and other, native fish. Decades ago, so many coho salmon filled the water that the noise of their jumping kept people in nearby houses up at night. On this day, Brown and his team find none.
Starting in June, months earlier than usual because of the drought, Brown and others with local environment group Salmon Protection and Watershed Network, will search the waterway. In cooperation with wildlife agencies, they will try to rescue coho and other fish stuck in drying pools of water 4- or 5 inches deep.
Sometimes, Brown said, the bucket brigades get there too late for the stranded salmon. "If they survived the raccoons" and other predators, "they dried up and died," Brown said.
Lehr, the fisheries chief, expects some individual steelhead trout in Southern California will get truck rides two or three times this summer, as parts of rivers and creeks disappear.
As a last resort, when some rivers have no pools of water left to shelter fish, wildlife officials will remove survivors to a hatchery to wait out the drought. Two such isolated native species from dried-up waterways have been living in government hatcheries since last year, snacking on flies that rangers catch in bug-zappers for them, Lehr said, and waiting for wetter times.

Study Examines Ecological Impact Of Sea-Ice Changes.The grounding of a giant iceberg in Antarctica has provided a unique real-life experiment that has revealed the vulnerability of marine ecosystems to sudden changes in sea-ice cover.

UNSW Australia scientists have found that within just three years of the iceberg becoming stuck in Commonwealth Bay - an event which dramatically increased sea-ice cover in the bay - almost all of the seaweed on the sea floor had decomposed, or become discoloured or bleached due to lack of light.

"Understanding the ecological effect of changes in sea-ice is vital for understanding the future impacts of climate change, but it is impossible to manipulate sea-ice at the scale we need to conduct experiments," says the study's lead author, UNSW's Dr Graeme Clark.

"Luckily, the grounding of an iceberg in Commonwealth Bay in 2010 provided us with a perfect natural experiment to carry out research on this important issue.

"Historically, the winds coming down from the Antarctic ice cap have kept the bay free of sea-ice for most of the year. But since the massive iceberg got stuck, the bay has been covered in sea-ice several metres thick, all year round," he says.

The study is published in the journal Polar Biology.

The scientists travelled to Commonwealth Bay in the east of the continent in December 2013, as part of the UNSW-led Australasian Antarctic Expedition 2013-2014, which retraced the route of Sir Douglas Mawson's scientific expedition a century before.

Dr Clark and team member, Dr Ezequiel Marzinelli, drilled through the sea ice in the bay and used underwater cameras to survey the seabed.

The UNSW team, led by Professor Emma Johnston, also examined the historical records made by Sir Douglas Mawson, who established his research station in Commonwealth Bay. Mawson's expedition used dredge hauls to survey the bay, which was then rarely covered in ice, in five locations during a two-year period from 1912 to 1913.

The UNSW researchers also compared their survey results with footage taken in the area in 2008 by underwater photographer Erwan Amice.

"After three years of sea-ice cover, the forests of healthy seaweeds that previously dominated the seabed were in a severe state of decline," says Professor Johnston, of the UNSW School of Biological, Earth and Environmental Sciences. Study Examines Ecological Impact Of Sea-Ice Changes

"About three quarters were decomposing, while the remainder were discoloured or bleached. However, darkness-adapted vertebrates such as brittle stars and fan worms were starting to colonise the bay."

Dr Marzinelli says: "This is the first time a shift from an algae-dominated ecosystem to an invertebrate-dominated one has been observed with a known start date. Continued sampling at the site would allow the rate at which this transition is occurring to be worked out."

Sea-ice not only affects how much light reaches the animals and plants living on the seabed, it regulates the amount of disturbance from drifting icebergs that scour the bottom, and determines the amount of detritus and vegetation that settles there.

Arctic OffShore Drilling

Arctic Drilling Protesters Block Oil Rig Entry Into Seattle Port. A few hundred critics of oil drilling in the Arctic Ocean blocked the entrances Monday to a seaport terminal in Seattle, where Royal Dutch Shell's massive floating oil rig will be loaded up before heading to the waters off Alaska this summer.
Protesters holding banners and flags marched across a bridge to Terminal 5, temporarily closing the road during Monday morning's commute. Once at the terminal, they spread out across the entrances.
Organizers say they plan to engage in civil disobedience to stop work on the drill rig, the latest protest of the 400-foot Polar Pioneer's arrival in Seattle. Protesters greeted the rig Thursday and then hundreds of activists in kayaks and other vessels turned out Saturday for a protest dubbed the "Paddle in Seattle."
Shell, which hopes to use the rig to explore for oil off Alaska's northwest coast, said it was planning to release a statement Monday.
Police say arrests are possible, but they expect the demonstration to be peaceful. A few dozen officers followed the march on foot and bicycle and kept watch at the terminal.
There were minimal operations at Terminal 5 "so there's not much to block," Port of Seattle spokesman Peter McGraw said. The operator of Terminal 18, a major hub of port activity where the march began, closed those gates in anticipation of the demonstration, he said.
Officials have been urging people to exercise their First Amendment rights safely, and "that's what we've been seeing so far," McGraw said.
The activists say they are concerned about the risk of an oil spill in the remote Arctic waters and the effects that tapping new frontiers of oil and gas reserves will have on global warming. Officials in Alaska have touted the economic benefits that drilling could bring there and to the Pacific Northwest.
On Monday, protesters of all ages sang, rapped and danced at the vehicle gate of Terminal 5. They chanted and held signs saying "Climate Justice For All" and "You Shell Not Pass."
Lisa Marcus, 58, a musician who participated in Saturday's protest, turned up with her "Love the planet" sign for another day of activism Monday.
"We've got to wake up" to the dangers of human-caused climate change, she said, ticking off a list of environmental problems that the world is facing. "Shell is trying to make it worse and that's not acceptable."

Global Warming And Population Shift Combining As The Perfect Heat Storm. The combination of global warming and shifting population means that by mid-century, there will be a huge increase in the number of Americans sweating through days that are extremely hot, a new study says.
People are migrating into areas - especially in the South - where the heat is likely to increase more, said the authors of a study published Monday by the journal Nature Climate Change. The study highlighted the Houston-Dallas-San Antonio and Atlanta-Charlotte-Raleigh corridors as the places where the double whammy looks to be the biggest. Global Warming And Population Shift Combining As The Perfect Heat Storm
"It's not just the climate that is changing in the future," said study co-author Linda Mearns, a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado. "It is many things: how many people and where people are that affects their exposure to climate changes."
In a unique study looking at the interplay of projected changes in climate and population, scientists tried to characterize the number of people who will feel temperatures of 95 degrees or higher and how often they will feel it. They used a figure called person days for the extreme heat to reflect both the length of time heat waves continued and how many people felt it by multiplying people affected by how many days they felt the heat.
Between 1970 and 2000, the U.S. averaged about 2.3 billion person days of extreme heat each year. But between 2040 and 2070 that number will be between 10 and 14 billion person days a year, according to the study.
The biggest projected increases in person days is the Texas, Oklahoma, Louisiana, Arkansas census region where by mid-century heat exposure will increase by 2.7 billion person days. Right behind is south Atlantic region of Florida, Georgia, South Carolina, North Carolina, Virginia, West Virginia, Maryland, Delaware and Washington, D.C., where heat exposure is projected to increase by 2.2 billion person days. New England gets off the easiest with an increase of only 71 million person days.
The scientists used 11 different climate models based on current trends of heat-trapping carbon dioxide emissions and matched those with demographic trends. Both the increased heat and population shifts had about equal effects but together they made matters even worse, said lead author Bryan Jones, a population geographer at the City University of New York. Global Warming And Population Shift Combining As The Perfect Heat Storm
The question is, will be people adapt by changing their lifestyle, such as staying indoors and using more air conditioning, or will they move to cooler climates. Jones said it is unlikely that people will move to cooler areas to escape the heat, saying historically people tend to move away from colder areas and into warmer areas like Florida, Arizona and North Carolina.
The scientists chose a threshold of 95 degrees because "at 95 people really, really start feeling it," Mearns said. "Even in a dry climate and I'm sitting here in Boulder, Colorado."
Several outside scientists praised the study. University of Georgia meteorology professor Marshall Shepherd said the problem is likely even worse when you take into consideration the fact that cities get hotter than rural areas.

Pouring Water Into Glass On Blue Background

California Expands Efforts To Protect Drinking Water. California regulators on Monday expanded their list of thousands of state-permitted oil and gas wells where below-ground injections may be contaminating drinking-water reserves.
State water officials already have acknowledged that improperly permitted oilfield operations have contaminated underground aquifers that are federally protected because they hold current or potential sources of drinking water.
An ongoing state review ordered by the U.S. Environmental Protection Agency has yet to break that down into whether any Californian is drinking contaminated water as a result of the improperly authorized oilfield operations, a state water official said.
"We don't really know yet," and the answer "is not going to be tomorrow," John Borkovich, chief of the state water board's groundwater monitoring section, told reporters. "There's a lot of data to collect."
The review by state oil and gas regulators identified in 2014 more than 2,500 oilfield wells that were injecting brine and other production and waste fluids into the federally protected water aquifers. State regulators this year and last ordered oil companies to shut 23 central California oilfield injection wells - 22 in Kern County and one in Tulare County - that officials said posed the biggest potential threat to nearby public water wells.
On Monday, regulators released a state letter sent Friday to the U.S. EPA identifying an additional 30 oilfield injection sites as high-priority potential risks to nearby water wells. State officials told reporters they believed many or all of the threatened water wells were not currently being used for drinking water or irrigation, however.
Unlike in the previous 23 oilfield operations closed by emergency state orders, regulators will wait for the oil companies in charge of those 30 drilling sites to completely assess the threat to local water wells before officials decide whether to shut those immediately as well.
For the first time, state regulators also disclosed that regulators have allowed 3,604 oil-industry wells to carry out cyclic-steam injection - a production method that repeatedly injects steam underground at high pressure -outside the approved boundaries of oilfields.
Environmental groups and some state lawmakers contend those cyclic-steam injection wells are illegal. In an email, Steven Bohlen, state oil and gas supervisor, said it was doubtful those 3,604 wells would raise any additional concerns about groundwater because they were injecting into underground areas that already contained hydrocarbon.
Bohlen added that "a higher level of scrutiny on such wells may be called for in the future."
Federal officials have approved a state timeline that would stop all oilfield injection into federally protected water aquifers in <a href="http://www.earth.com/image/tule-fog-across-californias-central-valley/">California</a> by February 2017.
"We are making good progress in addressing concerns about water quality that we all share," said Bohlen. California Expands Efforts To Protect Drinking Water
Some environmental organizations want the state to stop all oilfield injection into federally protected water aquifers immediately.
"I think it's remarkable that the extent of this crisis just keeps growing and yet state officials are doing essentially nothing to address it," said Kassie Siegel, senior counsel at the Arizona-based Center for Biological Diversity. "The commonsense first step is to stop the ongoing damage."
California is the country's third-biggest petroleum-producing state. Injection wells are involved in up to 85 percent of the state's production, the oil industry says.

New Texas Law Bans Cities From Banning Fracking. Republican Texas Gov.

Abbott said Monday he was protecting private property rights from the "heavy hand of local regulation."
He saw no contradiction in new state regulations superseding local voters' will, saying he believes "individuals have a much better idea how to run their own lives than do a bunch of government officials." Without an act of Congress, the President could not issue an outright ban on fracking across the US. There are, however, a number of regulatory and executive actions an administration could take to prevent or shrink the use of fracking technology, particularly on federal land.

The process involves the high-pressure injection of "fracking fluid" (primarily water, containing sand or other proppants suspended with the aid of thickening agents) into a wellbore to create cracks in the deep-rock formations through which natural gas, petroleum, and brine will flow more freely. When the hydraulic pressure is removed from the well, small grains of hydraulic fracturing proppants (either sand or aluminium oxide) hold the fractures open.

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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

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">

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.
