Balancing cleaner air with rising incomes is not a luxury question for developing countries. It is a real-world, and real-life, policy problem that shapes health, jobs, and the future of their cities.



A new <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">study</a> lays out when zero emissions can go hand in hand with steady <a href="https://www.earth.com/news/rising-temperatures-will-cut-world-gdp-by-a-staggering-40-percent-if-nothing-changes/">growth</a>, even when governments rely on foreign aid.



<h2 class="wp-block-heading" id="h-zero-emissions-and-economic-growth">Zero emissions and economic growth</h2>



The work comes from <a href="https://tus.elsevierpure.com/en/persons/hideo-noda" target="_blank" rel="noreferrer noopener">Hideo Noda</a> at the Tokyo University of Science (<a href="https://www.tus.ac.jp/en/" target="_blank" rel="noreferrer noopener">TUS</a>) with coauthor Fengqi Fang, a Ph.D. candidate in Business Administration from the Graduate School of Business Administration at TUS. 



The team builds a simple but testable way to check if a country can hit zero net <a href="https://www.earth.com/news/global-trade-is-fueling-a-dangerous-rise-in-methane-emissions/">emissions</a> while its economy keeps expanding.



They also verify the model numerically using real world style parameters so it is not just a chalkboard exercise. 



The paper connects theory to a specific United Nations target on decoupling growth from <a href="https://www.earth.com/news/limiting-global-warming-to-1-5c-is-almost-certainly-out-of-reach/">environmental damage</a>.



<h2 class="wp-block-heading" id="h-zero-emissions-models">Zero emissions models</h2>



First, the authors define a zero-emissions <a href="https://www.un.org/en/climatechange/net-zero-coalition" target="_blank" rel="noreferrer noopener">policy</a> as keeping net pollution at zero at every point in time, by matching abatement to emissions. That requires money, technology, and clear rules to assign who pays.



They run two versions of the economy. 



One is a public goods <a href="https://scholar.harvard.edu/files/stantcheva/files/lecture8.pdf" target="_blank" rel="noreferrer noopener">model</a> where government services like roads or schools lift private production for everyone at once, a standard growth <a href="https://www.journals.uchicago.edu/doi/10.1086/261726" target="_blank" rel="noreferrer noopener">model</a> introduced by Robert Barro in 1990. 



The second adds <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">congestion</a>, where more people share the same public services so the boost per person shrinks.



<h2 class="wp-block-heading" id="h-minimum-income-rule">Minimum income rule</h2>



The key test is whether gross domestic product (<a href="https://data.worldbank.org/indicator/NY.GDP.PCAP.CD" target="_blank" rel="noreferrer noopener">GDP</a>) per capita rises above a minimum income threshold so a country can fully clean what it emits. 



The authors call this the kindergarten rule level of abatement, as in: “clean-up what you make dirty.”



"Following the Kindergarten rule means implementing zero emission technologies in either finite time or asymptotically," noted M. Scott Taylor and William Brock in their related <a href="https://www.nber.org/papers/w9597" target="_blank" rel="noreferrer noopener">study</a>. 



This frame anchors the new threshold concept for developing countries.



<h2 class="wp-block-heading" id="h-aid-supports-clean-income-growth">Aid supports clean income growth</h2>



Many low income governments fund services with official development assistance (<a href="https://www.oecd.org/en/topics/policy-issues/official-development-assistance-oda.html" target="_blank" rel="noreferrer noopener">ODA</a>), so the model lets outside aid pay for both cleaning and public services. 



That design reflects classic work showing how aid aimed at productive public services can shift long run growth.



In related <a href="https://www.sciencedirect.com/science/article/abs/pii/S0304387806000290" target="_blank" rel="noreferrer noopener">theory</a>, flexible labor and aid tied to public capital influence the path of output and welfare. The new paper extends this logic to pollution control that must be paid for every year.



<h2 class="wp-block-heading" id="h-changing-income-threshold">Changing income threshold</h2>



The threshold depends on clean technology, population size, and how much aid is fixed to environmental <a href="https://www.earth.com/news/expanding-oil-and-gas-fields-threaten-global-climate-goals/">uses</a>. Better abatement technology lowers the income bar because each dollar of cleanup removes more pollution.



Population matters differently across the two models. In the public goods case, a larger labor force can raise growth because services scale with the economy, while in the congestion case that scale effect drops out as services get diluted.



<h2 class="wp-block-heading" id="h-taxes-and-zero-emissions-targets">Taxes and zero emissions targets</h2>



The model also looks at tax policy, focusing on a labor income tax that finances services. 



There is a tax rate that maximizes the growth of income per person, and under both models governments can reach the needed income threshold in finite time if they choose that growth maximizing rate.



Public services that complement private capital are the link. When governments tax and spend on those services efficiently, private firms produce more and the <a href="https://www.earth.com/news/climate-action-economies-can-grow-while-cutting-emissions/">economy climbs</a> to the income level that makes full abatement feasible.



"Both models indicate that implementing the zero-emissions policy is compatible with sustainable economic growth," wrote Noda. 



They also show the kindergarten rule threshold is higher with congestion than without it, so crowding of public services slows the crossing.



"We call this threshold the kindergarten rule level of pollution abatement in terms of GDP per capita," wrote Noda. The result gives policymakers a clear income target, not just a slogan about decoupling.



<h2 class="wp-block-heading" id="h-income-growth-and-sdgs">Income growth and SDGs</h2>



Target 8.4 of the Sustainable Development Goals (<a href="https://www.undp.org/sustainable-development-goals" target="_blank" rel="noreferrer noopener">SDGs</a>) asks countries to decouple growth from environmental degradation. 



The authors argue their framework helps explain when that is possible in practice, and how policy levers change the timing.



The UN defines the <a href="https://metadata.un.org/sdg/8.4" target="_blank" rel="noreferrer noopener">target</a> as improving resource efficiency and decoupling growth from environmental harm through 2030. The paper’s threshold view fits that mandate with a concrete yardstick.



<h2 class="wp-block-heading" id="h-why-results-still-matter">Why results still matter</h2>



Earlier <a href="https://www.sciencedirect.com/science/article/abs/pii/S0959652621009112" target="_blank" rel="noreferrer noopener">work</a> in the same research stream focused on developed, innovation-driven economies and showed that zero emissions could be achieved alongside continued growth. 



That study examined whether sustained economic expansion could occur while also maintaining <a href="https://www.earth.com/news/a-net-zero-world-will-require-75-trillion-of-investment-and-1-billion-electric-cars/">zero net pollution emissions</a>.



The new paper shows the same compatibility can hold in aid dependent settings where innovation is not the main growth engine. 



That extension fills a real gap, because many low income countries face tighter fiscal and technological limits.



Build or buy cleaner technology so the threshold falls. Treat tied aid for environmental programs as a growth tool and not just a cost center.



Set tax policy to raise the growth rate of income per person, then sustain it long enough to pass the threshold. Guard against congestion by scaling services with population, so gains are not diluted.



The study is published in <a href="https://www.worldscientific.com/doi/10.1142/S0217590825500304" target="_blank" rel="noreferrer noopener">The Singapore Economic Review</a>.

Colorado Gold King Mine Spill Sparks Changes In Warning System. A massive wastewater spill from an old gold mine in Colorado has prompted state officials to expand the list of downstream users they will warn after such accidents.
Last month, Colorado health officials notified only agencies inside the state after 3 million gallons of water tainted with heavy metals gushed out of the Gold King mine near Silverton and eventually reached the Animas, San Juan and Colorado rivers in New Mexico and Utah.
In the future, the Colorado Department of Public Health and Environment will warn downstream states as well, department spokesman Mark Salley said.
Colorado officials didn't know the magnitude of the spill when they issued their warnings, he said.
Officials in New Mexico were unhappy because they say the federal Environmental Protection Agency didn't alerted them when an EPA-supervised crew inadvertently triggered the spill about 70 miles from the New Mexico border.
The crew was trying to enter the mine as part of a cleanup operation and breached a debris pile that was holding back the water.
New Mexico officials first heard about the spill nearly 24 hours after it happened from the Southern Ute Indian Tribe, not the EPA, said Chris Sanchez, a spokesman for Gov. Susana Martinez.
The Southern Ute reservation straddles the Animas River in <a href="http://www.earth.com/image/cameron-peak-fire-is-now-the-largest-in-colorados-recorded-history/">Colorado</a>, and tribal officials had been alerted by the Colorado health department.
New Mexico officials contacted the EPA after hearing from the Southern Utes, Sanchez said.
"The EPA to this day has not been able to answer why the agency never contacted the state of New Mexico," Sanchez said in an email to The Associated Press.
EPA spokesman David Gray said he spoke to New Mexico's Environment Department about the spill at midday Aug. 6, a day after it occurred. Gray, who works in the EPA's Dallas regional office, said that was shortly after he learned about it.
New Mexico is part of a Dallas-based EPA region; Colorado is part of a separate region with headquarters in Denver.
The EPA has come under sharp criticism for causing the spill and for its handling of the aftermath. At least four congressional committee hearings are scheduled, starting Sept. 9.
The EPA's inspector general is investigating. The Interior Department, which is separate from the EPA, is also investigating, with the help of the Army Corps of Engineers.
EPA Administrator Gina McCarthy has said the agency accepts responsibility for the spill, calling it tragic and unfortunate. Colorado Gold King Mine Spill Sparks Changes In Warning System
The EPA has said water quality is returning to pre-spill levels. Colorado health officials said it is safe to eat trout from the Animas River.

China's Loess Plateau was formed by wind alternately depositing dust or removing dust over the last 2.6 million years, according to a new report from University of<a href="http://www.earth.com/news/arizona-rock-will-help-solve-mysteries-of-the-triassic/"> Arizona</a> geoscientists.

The study is the first to explain how the steep-fronted plateau formed.

Wind blew dust from what is now the Mu Us Desert into the huge pile of consolidated dust known as the Loess Plateau, said lead author Paul Kapp, a UA professor of geosciences.

Just as a leaf blower clears an area by piling leaves up along the edge, the wind did the same thing with the dust that was once in the Mu Us Desert.

"If the blower keeps blowing the leaves, they move backward and the pile of leaves gets bigger," Kapp said. "There's a boundary between the area of leaves and no leaves."

About the size of the state of Arizona, the Loess Plateau is the largest accumulation of dust on Earth. Deposits of wind-blown dust known as "loess" generally create good agricultural soil and are found in many parts of the world, including the U.S. Midwest.

The UA team also found that, just as a leaf blower moves a pile of leaves away from itself, wind scours the face of the plateau so forcefully that the plateau is slowly moving downwind.

"You have a dust-fall event and then you have a wind event that blows some of the dust away," Kapp said. "The plateau is not static. It's moving in a windward direction."

Linear ridges on the top of the Loess Plateau are also sculpted by the wind, the researchers found.

"The significance of wind erosion shaping the landscape is generally unappreciated," Kapp said. "It's more important than previously thought."

The team's paper, "From dust to dust: Quaternary wind erosion of the Mu Us Desert and the Loess Plateau, China," is scheduled for publication in the September issue of the journalGeology and is currently <a href="http://geology.gsapubs.org/content/early/2015/07/28/G36724.1.abstract" target="_blank" rel="noopener noreferrer">online.</a>

Kapp's co-authors are UA geoscientists Alex Pullen, Jon Pelletier, Joellen Russell, Paul Goodman and former UA geosciences postdoctoral researcher Fulong Cai, now at the Institute of Tibetan Plateau Research in Beijing. The National Science Foundation funded the research.

To track down the source of the Loess Plateau's dust, Kapp, Pullen and Cai went to China's deserts in 2013 during March--prime season for dust storms. The researchers hoped to experience dust storms first-hand.

While standing atop one of the plateau's linear ridges during a dust storm, the researchers noticed the wind was blowing parallel to the ridge's long axis.

Kapp said they each had the same realization at the same time: The plateau itself was being sculpted by the wind. The plateau is not just a sink for dust, but is also a source of dust.

"You have to live it for it to really sink in," he said. "You have to be out there in the field when the wind is blowing."

Once back at the UA, Kapp fired up Google Earth to see satellite images of the plateau. He saw linear ridges just a few kilometers long--ridges like the ones he'd stood on.

To learn more, he started mapping the ridges in the satellite images.

"I mapped stuff like crazy, for weeks and weeks--I measured the orientation of about three thousand ridges from these images," he said.

The ridges ran northwest-southeast in the northern part of the plateau and ran more north-south in the southern part.

To compare the orientation of the ridges to the orientation of the winds, he asked Russell to make a map of the modern-day wind patterns over the Mu Us desert and the Loess Plateau.

The wind pattern map, especially the winter and spring dust storm winds, matched the orientation of the ridges on top of the plateau.

"I've never seen anyone look at the wind-related geomorphology and actually relate it to climatology at the large scale of the entire Mu Us Desert and Loess Plateau," Kapp said. "It's a rare approach."

The team's ideas definitely are applicable to the formation of other areas of loess deposits on Earth, Kapp said, adding, "But nothing compares to the size of the Loess Plateau."

He continues to be fascinated by how wind shapes planets. Kapp's next step is looking at other wind-eroded landscapes on Earth and also on Mars.

Group Fails To Reach Agreement To Save Bluefin Tuna. An international body that monitors fisheries in most of the Pacific Ocean ended a meeting in Japan on Thursday without agreement on fresh measures to protect the dwindling bluefin tuna.
The Western and Central Pacific Fisheries Commission was unable to get a consensus on either short-term or long-term measures to help restore the bluefin population, whose numbers are estimated to have fallen 96 percent from unfished levels.
Last year, the 10-nation commission recommended that the catch of juvenile tuna be cut to half of its average level in 2002-2004. But conservation groups say more must be done to counter the sharp decline of the species.
The lack of a required three-quarters quorum prevented any agreement, since representatives from China, the Cook Islands, Vanuatu and the Philippines did not attend. So any decisions on new long-term measures were pushed back to 2016, the Japanese Fisheries Agency said.
Further inaction would likely prompt efforts by conservationists to get <a href="https://www.bing.com/search?q=pacific&amp;cvid=faf7d6ec872040de81efcec843997ca8&amp;FORM=ANAB01&amp;PC=HCTS">Pacific</a> bluefin tuna banned from international trading, said a statement by The Pew Charitable Trusts, which is working to save the species.
"Unfortunately, the only outcome of this week's meeting is a guarantee that the Pacific bluefin tuna population will decline even further because of the continued inaction of ten governments responsible for the management of this species," Amanda Nickson, director of global tuna conservation for the group.
"The international community may be forced to look at a global trade ban to help save this species," she said in a statement.
The fisheries group also did not agree to a request by researchers to study the results of stricter fisheries management during their four-day meeting in the northern city of Sapporo.
Japanese eat 80 percent of the world's bluefin tuna, or "hon maguro," a sushi mainstay, and demand elsewhere in the world has kept growing. At a ritual new year auction, the top price for the fish jumped to about $7,000 a kilogram in 2013 but was a more reasonable $208 per kilogram this year.
Most of the fish caught are juveniles that have not had a chance to reproduce. The species could recover relatively quickly, however, since they are highly productive, spawning millions of eggs a year.
The environmental group Greenpeace praised <a href="http://www.earth.com/news/nearly-all-native-japanese-bats-are-endangered/">Japanese</a> representatives for proposing emergency measures to help the bluefin tuna, but said given the severity of its decline Japan should restrict sales of the fish.
A stock assessment by the International Scientific Committee for Tuna and Tuna-like Species in the Northern Pacific Ocean found the levels of bluefin in 2012 at near their lowest ever of just 4 percent of original stocks. Group Fails To Reach Agreement To Save Bluefin Tuna

Washington State Sues Feds Over Nuclear Waste Tanks. Washington state is suing the federal government again over cleanup of nuclear waste tanks at the Hanford Nuclear Reservation - this time over the danger posed to workers by vapor releases from underground waste-storage tanks.
In a federal lawsuit filed in Spokane on Wednesday, state Attorney General Bob Ferguson said the U.S. Department of Energy has known about vapors sickening workers at the site since at least the late 1980s, but hasn't fixed it - even though agencies have issued 19 reports on the problem. Hanford, on the <a href="https://www.bing.com/search?q=Columbia+River&amp;cvid=59d6fe4485b7446aa604b86def4369bc&amp;FORM=ANAB01&amp;PC=HCTS">Columbia River</a> in eastern Washington, produced plutonium for nuclear weapons from 1943 to 1987.
There were more than 50 reports of workers being exposed to vapors between January 2014 and April 2015, Ferguson said, and hundreds over the past few decades, with victims suffering from symptoms that include nosebleeds, brain damage and permanent loss of lung capacity. One longtime worker, Gary Sall, died from brain swelling linked to chemical vapors in 2011. Washington State Sues Feds Over Nuclear Waste Tanks
"Neither the Department of Energy nor its contractors have followed through to finally fix the problem and keep our workers safe," Ferguson told a news conference. "If you visited Hanford today, you'd find some workers at the tank farms still exposed to vapors seeping out of these tanks."
The lawsuit also names the Energy Department's contractor at Hanford, <a href="http://www.earth.com/image/mount-rainier-in-washington/">Washington</a> River Protection Solutions, as a defendant. An advocacy group for Hanford workers, Hanford Challenge, and a union representing some of them, United Association of Steamfitters and Plumbers Local 598, filed a companion lawsuit.
In statements Wednesday, the department and its contractor said steps have already been taken to improve worker safety at the site, such as by increasing the use of self-contained breathing devices in areas of potential vapor exposure.
"The Department's top priority is the protection of our workforce, the public and the environment," Energy spokeswoman Carrie Meyer said in an email.
Washington River Protection Solutions said that since it took over as the contractor for tank operations in 2008, it has increased and improved sampling methods for detecting vapors and created wider vapor control zones for workers, and it's working on a multiyear plan to improve monitoring for vapors, among other things.
Washington sued the Energy Department in 2008 over the glacial pace of cleanup at Hanford, and the federal government agreed to a timeline for cleanup in a 2010 settlement. It's lagging in meeting those goals.
The Energy Department already asked for a one-year extension of its deadline for emptying nine leak-prone tanks, saying that having more employees wear respirators was slowing down the work.
Some 56 million gallons of toxic waste - much of it radioactive - is stored in 177 underground tanks on the 586-square-mile reservation. Most of the tanks are single-shelled and considered inadequate, and workers have been transferring the waste inside them to double-shelled tanks. The tanks are vented to keep dangerous gases from building up inside and causing explosions. While the vents do have filters that capture toxic particulates, the filters don't capture chemical vapors.
Current and former Hanford workers who attended Ferguson's news conference described a patchwork of safety practices that lead to some people carrying full breathing apparatus - like the air tanks firefighters carry into a burning building - while others nearby have no protection.
Pete Nicacio, business manager for Local 598, scoffed at Hanford's use of a rope delineating where workers need to wear breathing gear and where they don't, saying workers call it "the magic rope." He said his union members insist on breathing gear, and as a result, bosses have sometimes taken work away from them.
Tom Carpenter, executive director of Hanford Challenge, said a major problem is that Hanford doesn't have monitoring systems sophisticated enough to know what gases workers have been exposed to - some of which are dangerous enough to cause health problems at infinitesimally low concentrations. More than 1,500 chemical gases have been found in the tanks, and doctors are often forced to try to figure out which ones workers might have been exposed to based only on their symptoms.
Diana Gegg, 64, was working as a heavy equipment operator at Hanford one day in 2007 when she smelled something like chlorine or ammonia. She became dizzy and developed "flu-like symptoms which never went away and still haven't," as well as a bad stutter and memory problems.
After the news conference, she handed a reporter a typed statement because of her difficulty speaking.
Another worker, electrician Steve Lewis, said he has experienced inflamed skin and continual congestion in his throat. But, he added, "I've watched other people deal with things that were way worse than that."

Extra CO2 Can Help Plants But Only At Low Temperatures. Researchers say it's important to better understand the interplay between plant communities and the changing ratios of chemicals in the atmosphere and ocean.

Phytoplankton are plant-like microorganisms that serve as the foundation for many marine food chains. Like plants, phytoplankton covert sunlight into chemical energy and carbon dioxide into oxygen.

Logic suggests that extra CO2 would be advantageous to phytoplankton. But a new study in the Arctic Ocean suggests growing levels of <a href="https://www.bing.com/search?q=carbon+dioxide&amp;cvid=8500f90c42734c019bf44b3fda8c471a&amp;FORM=ANAB01&amp;PC=HCTS">carbon dioxide</a> offer a boost only at low temperatures.

According to researchers at the University of Western Australia, rising CO2 concentrations in Arctic waters are having a positive effect on phytoplankton growth -- but that effect fades as water temperatures rise. Extra CO2 Can Help Plants But Only At Low Temperatures

"This influx of CO2 could benefit primary producers, but we cannot forget that the temperature of the Arctic Ocean is also increasing almost three times faster than global temperatures," Lara Garcia-Corral, a researcher with UWA's Oceans Institute and School of Plant Biology, explained in a press release.

Extra CO2 Can Help Plants But Only At Low Temperatures

Extra CO2 Can Help Plants But Only At Low Temperatures....

Researchers say it's important to better understand the interplay between plant communities and the changing ratios of chemicals in the atmosphere and ocean.

Phytoplankton are plant-like microorganisms that serve as the foundation for many marine food chains. Like plants, phytoplankton covert sunlight into chemical energy and carbon dioxide into oxygen.

Logic suggests that extra CO2 would be advantageous to phytoplankton. But a new study in the Arctic Ocean suggests growing levels of carbon dioxide offer a boost only at low temperatures.

According to researchers at the University of Western Australia, rising CO2 concentrations in Arctic waters are having a positive effect on phytoplankton growth -- but that effect fades as water temperatures rise.

"This influx of CO2 could benefit primary producers, but we cannot forget that the temperature of the Arctic Ocean is also increasing almost three times faster than global temperatures," Lara Garcia-Corral, a researcher with UWA's Oceans Institute and School of Plant Biology, explained in a press release.

Washington State Sues Feds Over Nuclear Waste . Washington state is suing the federal government again over cleanup of nuclear waste tanks at the Hanford Nuclear Reservation - this time over the danger posed to workers by vapor releases from underground waste-storage tanks.
In a federal lawsuit filed in Spokane on Wednesday, state Attorney General Bob Ferguson said the U.S. Department of Energy has known about vapors sickening workers at the site since at least the late 1980s, but hasn't fixed it - even though agencies have issued 19 reports on the problem. Hanford, on the Columbia River in eastern Washington, produced plutonium for<a href="http://www.earth.com/news/radioactive-carbon-from-nuclear-bomb-tests/"> nuclear</a> weapons from 1943 to 1987.
There were more than 50 reports of workers being exposed to vapors between January 2014 and April 2015, Ferguson said, and hundreds over the past few decades, with victims suffering from symptoms that include nosebleeds, brain damage and permanent loss of lung capacity. One longtime worker, Gary Sall, died from brain swelling linked to chemical vapors in 2011. Washington State Sues Feds Over Nuclear Waste Tanks
"Neither the Department of Energy nor its contractors have followed through to finally fix the problem and keep our workers safe," Ferguson told a news conference. "If you visited Hanford today, you'd find some workers at the tank farms still exposed to vapors seeping out of these tanks."
The lawsuit also names the Energy Department's contractor at Hanford, <a href="https://www.bing.com/search?q=Washington&amp;cvid=e3b63710753b4b7d9fbd974d38e5ed5a&amp;FORM=ANAB01&amp;PC=HCTS">Washington</a> River Protection Solutions, as a defendant. An advocacy group for Hanford workers, Hanford Challenge, and a union representing some of them, United Association of Steamfitters and Plumbers Local 598, filed a companion lawsuit.
In statements Wednesday, the department and its contractor said steps have already been taken to improve worker safety at the site, such as by increasing the use of self-contained breathing devices in areas of potential vapor exposure. Washington State Sues Feds Over Nuclear Waste Tanks
"The Department's top priority is the protection of our workforce, the public and the environment," Energy spokeswoman Carrie Meyer said in an email. Washington State Sues Feds Over Nuclear Waste Tanks
Washington River Protection Solutions said that since it took over as the contractor for tank operations in 2008, it has increased and improved sampling methods for detecting vapors and created wider vapor control zones for workers, and it's working on a multiyear plan to improve monitoring for vapors, among other things.
Washington sued the Energy Department in 2008 over the glacial pace of cleanup at Hanford, and the federal government agreed to a timeline for cleanup in a 2010 settlement. It's lagging in meeting those goals.
The Energy Department already asked for a one-year extension of its deadline for emptying nine leak-prone tanks, saying that having more employees wear respirators was slowing down the work.
Some 56 million gallons of toxic waste - much of it radioactive - is stored in 177 underground tanks on the 586-square-mile reservation. Most of the tanks are single-shelled and considered inadequate, and workers have been transferring the waste inside them to double-shelled tanks. The tanks are vented to keep dangerous gases from building up inside and causing explosions. While the vents do have filters that capture toxic particulates, the filters don't capture chemical vapors.
Current and former Hanford workers who attended Ferguson's news conference described a patchwork of safety practices that lead to some people carrying full breathing apparatus - like the air tanks firefighters carry into a burning building - while others nearby have no protection.
Pete Nicacio, business manager for Local 598, scoffed at Hanford's use of a rope delineating where workers need to wear breathing gear and where they don't, saying workers call it "the magic rope." He said his union members insist on breathing gear, and as a result, bosses have sometimes taken work away from them.
Tom Carpenter, executive director of Hanford Challenge, said a major problem is that Hanford doesn't have monitoring systems sophisticated enough to know what gases workers have been exposed to - some of which are dangerous enough to cause health problems at infinitesimally low concentrations. More than 1,500 chemical gases have been found in the tanks, and doctors are often forced to try to figure out which ones workers might have been exposed to based only on their symptoms.
Diana Gegg, 64, was working as a heavy equipment operator at Hanford one day in 2007 when she smelled something like chlorine or ammonia. She became dizzy and developed "flu-like symptoms which never went away and still haven't," as well as a bad stutter and memory problems.
After the news conference, she handed a reporter a typed statement because of her difficulty speaking.
Another worker, electrician Steve Lewis, said he has experienced inflamed skin and continual congestion in his throat. But, he added, "I've watched other people deal with things that were way worse than that."

Kivalina, Alaska Will Be A Global Warming Casualty Within A Decade. Residents of a Native village threatened by erosion were thankful for President Barack Obama's attention to their plight, saying they hope his visit to Alaska will help them secure funding to build a critical evacuation road to drier ground.
Even with a protective ocean rock wall, the impoverished Inupiat Eskimo community of Kivalina has no more than a decade left before erosion begins to force people from their homes, said Millie Hawley, president of Kivalina's tribal council.
Villagers say a couple homes near the village lagoon are already threatened by <a href="http://www.earth.com/news/oahu-could-lose-40-percent-of-its-beaches-to-coastal-erosion/">erosion</a>, which has come within 3 feet of the foundation of one dwelling. Kivalina, Alaska Will Be A Global Warming Casualty Within A Decade
With about 400 people, Kivalina is located at the tip of a barrier reef 80 miles northwest of the regional hub of Kotzebue, where Obama was scheduled to visit Wednesday during his tour of Alaska to show the effects of climate change.
In July, a White House advance team visited Kivalina about 625 miles northwest of Anchorage to scope it out as a possible stop for the president, but the visit didn't materialize.
The president, however, did get a look at Kivalina on Wednesday as Air Force One did a flyover when it was en route to Kotzebue. The president's plane came down low to the ground, and the village was visible on the left side of the plane.
The pilots turned the plane around to fly over Kivalina again so the president could get a second look.
"On my way here, I flew over the island of Kivalina, which is already receding into the ocean," Obama said during his address in Kotzebue.
He described how waves sweep across the entire barrier island at times.
"For many of those Alaskans, it's no longer a question of if they are going to relocate, but when," Obama said. "Think about that. If another country tried to do wipe out an entire town, we'd do everything in our power to protect it."
Hawley was among 10 village leaders who flew by charter plane to Kotzebue, and she introduced the president before his address.
"I think we're in a prominent place to get our issues addressed on climate change," Hawley said. "It's all about life safety and food security."
Brian Deese, Obama's senior adviser for climate and energy issues, said the federal government was working to address concerns in Kivalina and similar villages that find it hard to access federal funds for relocation.
He said that Alaska Natives had identified USDA water infrastructure grants as a particular source of funding that could be helpful.
Hawley said the village wants to build a 7-mile evacuation road and causeway to the mainland where residents voted several years ago to build a future school at a potential relocation site.
Erosion is only part of the impact of climate change, which is accelerating in the Arctic. Villagers say the migrations of animals they rely on for much of their diet, such as bearded seal and caribou, have become unpredictable and is taking place far earlier. That is forcing residents to travel farther to hunt.
For the past few years, the caribou that used to show up by the thousands near the village have all but disappeared.
Also, the ice that protects the shores from storm surges is forming later and melting earlier, allowing stronger storms to lash out at the eroding coastline.
Joseph Swan Jr., who manages Kivalina's water plant, has lived in the village all his 47 years. He welcomed the opportunity for the village to be on Obama's radar because the president has global influence.
"It's great that somebody's finally paying attention, real attention, and letting us know we're not invisible," Swan said.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Today’s Video of the Day from 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.
