<a href="https://www.earth.com/news/grapevines-could-offer-a-breakthrough-alternative-to-plastic-packaging/">Plastic</a> bags are everywhere, and too many slip into rivers and onto beaches. A new analysis finds that policies that either charge a small fee per bag or prohibit them outright cut the share of bags found during shoreline cleanups by 25 to 47 percent.



The study combed through hundreds of city, county, and state rules passed between 2017 and 2023. It matched those policies to more than 45,000 volunteer cleanups across the United States to see what actually changed on the ground.



<h2 class="wp-block-heading" id="h-who-ran-the-study">Who ran the study</h2>



The research was coauthored by <a href="https://www.udel.edu/academics/colleges/ceoe/departments/smsp/faculty/kimberly-oremus/" target="_blank" rel="noreferrer noopener">Kimberly L. Oremus</a> of the University of Delaware’s School of Marine Science and Policy (<a href="https://www.udel.edu/academics/colleges/ceoe/departments/smsp/" target="_blank" rel="noreferrer noopener">UDEL</a>). 



Oremus and her collaborator set out to measure litter, not just shopping behavior, so the results speak to what ends up in nature.



The team relied on citizen science, meaning trained volunteers recorded what they collected during beach, river, and lake cleanups. 



They drew on <a href="https://www.coastalcleanupdata.org/" target="_blank" rel="noreferrer noopener">TIDES</a>, a public database that stores those counts in one place so researchers can analyze patterns across time and place.



<h2 class="wp-block-heading" id="h-studying-plastic-bag-policies">Studying plastic bag policies</h2>



To isolate the effect of bag policies, the authors used a Difference-in-Differences (<a href="https://www.publichealth.columbia.edu/research/population-health-methods/difference-difference-estimation" target="_blank" rel="noreferrer noopener">DiD</a>) approach that compares places with and without new laws over the same period. 



That design helps rule out unrelated trends that affect everyone, such as national shifts in shopping or packaging.



The headline result is simple. In communities with full bans or fees, the share of <a href="https://www.earth.com/news/drinking-from-plastic-bottles-linked-to-high-blood-pressure-and-heart-problems/">plastic</a> bags in the litter mix fell relative to similar places without policies, and the decline grew in the years after a law took effect.



State level rules tended to be more reliable in the data than city or county policies. Effects looked similar along coasts and rivers, with hints of larger gains along lakes where winds and currents spread litter differently.



<h2 class="wp-block-heading" id="h-plastic-policy-fees-vs-bans">Plastic policy: Fees vs. bans</h2>



Fees change the default at every checkout and discourage taking a bag when you do not need one, which reduces both thin and thicker bag use.



Other <a href="https://www.gov.uk/government/publications/carrier-bag-charge-summary-of-data-in-england/single-use-plastic-carrier-bags-charge-data-for-england-2024-to-2025" target="_blank" rel="noreferrer noopener">evidence</a> points in the same direction outside the United States. England reports an almost 98 percent drop in single use carrier bags at major retailers since its charge began.



Policies that only restrict thin bags often allow thicker <a href="https://www.earth.com/news/agricultural-soil-is-now-the-worlds-biggest-plastic-dumping-ground/">plastic</a> labeled as reusable. 



Those partial bans showed the smallest and least precise effects in the analysis, which is consistent with shoppers substituting one kind of plastic for another.



Some states also pass preemption <a href="https://www.ncsl.org/environment-and-natural-resources/state-plastic-bag-legislation" target="_blank" rel="noreferrer noopener">laws</a> that block cities and counties from regulating bags at all. When local governments cannot act, the study’s data suggest statewide policies become especially important.



<h2 class="wp-block-heading" id="h-wildlife-and-entanglement">Wildlife and entanglement</h2>



The cleanup records include notes on animals found <a href="https://www.earth.com/news/microplastics-found-in-99-percent-sea-turtles-organ-tissue-reproductive-system/">entangled in debris</a>. 



In areas with bag policies, the presence of entangled animals dropped by roughly 30 to 37 percent, although the authors caution that the estimates are imprecise and more data are needed.



That finding aligns with what we know about <a href="https://www.nrdc.org/stories/single-use-plastics-101" target="_blank" rel="noreferrer noopener">single-use-plastics</a>. Thin bags linger in water and along shorelines, where they can snag, smother, or be eaten by turtles, birds, and fish.



Many studies track what happens at store checkouts, but fewer track what ends up outdoors. Shoreline cleanups offer a window into that last step in the chain from purchase to pollution.



Across the study period, the share of bags among collected items rose overall, but it rose less where bag laws existed. That pattern is exactly what you want to see if policies are slowing the flow of litter into the environment.



<h2 class="wp-block-heading" id="h-global-plastic-policy-steps">Global plastic policy steps</h2>



A small, universal fee is a simple tool that nudges behavior without banning choices. Full bans can work too, and the analysis shows both approaches reduce the share of <a href="https://www.earth.com/news/glass-bottles-contain-more-microplastics-than-plastic-containers/">plastic</a> bags found during cleanups.



The mix of policies should match local conditions. In places with more bag litter to begin with, impacts were largest, so targeting high problem areas with fast action can deliver quick gains.



Plastic bag rules are only one part of the picture. Negotiators from 175 countries are working toward a plastics treaty under <a href="https://www.unep.org/inc-plastic-pollution" target="_blank" rel="noreferrer noopener">UNEP</a> that could standardize action on a wider set of products and chemicals.



The study notes that bottles, caps, and other items did not decline when bag policies passed. That is a signal that targeted rules for other single use products would be needed to curb overall litter.



Adopt a modest fee or a full ban that applies across retail and restaurant settings, and keep the text simple so it is easy to enforce. Pair the policy with clear signs at checkout and with retailer reporting that tracks compliance.



Measure results in the same way the researchers did. Recruit volunteers, log items in TIDES, and watch how the litter mix changes year over year so the policy can be adjusted as needed.



The study is published in <a href="https://www.science.org/doi/10.1126/science.adp9274" target="_blank" rel="noreferrer noopener">Science</a>.

Studies confirm that a small tax definitely helps curb plastic pollution

The review was announced late Tuesday after elected officials from both parties questioned whether the Environmental Protection Agency should be left to probe its own heavily criticized response to the disaster. EPA and contract workers accidentally unleashed 3 million gallons of contaminated wastewater on Aug. 5 as they inspected the idled Gold King mine.

The Interior Department's report is expected to be released publicly in 60 days.
In addition, EPA's inspector general is conducting a separate review. Leaders of oversight committees in both the House and Senate say they are planning hearings after Congress returns from its August recess.
All six senators from the three states involved - Colorado, <a href="http://www.earth.com/news/carlsbad-caverns-new-mexico/">New Mexico</a> and Utah - wrote EPA Inspector General Arthur Elkins on Wednesday asking him to look into more than a dozen questions, including details of the work being done when the spill occurred and the qualifications of the on-scene crew.
The senators also asked what laws and policies govern the EPA's communications with state, local and tribal governments after such an incident and whether the agency met those requirements.
Numerous local officials have complained the EPA was slow to notify them. The senators asked whether the time lapse created any health hazards or delayed the response.
New Mexico Gov. Susana Martinez on Wednesday called for her state's environment department to launch its own investigation. Aside from what led up to the spill, she said the investigation will examine how residents, businesses and communities along the rivers were notified in the aftermath of the spill.
"New Mexicans deserve answers as to why this catastrophe happened and why the EPA failed to notify us in a timely manner," she said, adding that the federal agency has hounded private citizens and businesses for doing far less.
Utah Attorney General Sean Reyes toured the site of the spill Wednesday and said he's weighing possible legal action if the EPA's proposal to fix the damage in his state falls short.

Warming Temperatures Are Forcing Eastern Brook Trout To Relocate. When trying to explain the potential effects of climate change on plants, fish and wildlife, scientists usually resort to language that fails to convey the impact of warming. Now, a study by Penn State's College of <a href="http://www.earth.com/news/climate-smart-agricultural-practices-will-boost-global-food-security/">Agricultural</a> Sciences fisheries researchers clearly explains the impact of projected warming waters on wild brook trout in the eastern U.S. for fishermen.

The eastern brook trout is a socially and economically important fish that occurs in small cold water streams and lakes, and self-sustaining populations support angling throughout the Appalachian Mountains, from Maine to Georgia. However, warming air temperatures are expected to reduce available cold-water habitat and result in a smaller brook trout distribution and fewer angling opportunities.Warming Temperatures Are Forcing Eastern Brook Trout To Relocate

Building on recent research at Penn State, Tyler Wagner, adjunct professor of fisheries and Tyrell DeWeber, now a postdoctoral scholar at <a href="https://www.bing.com/search?q=oregon&amp;cvid=593c3a59910343438ec4024e80ddd9c7&amp;FORM=ANAB01&amp;PC=HCTS">Oregon</a> State University, used two models they previously developed, one predicting stream temperature and one predicting where brook trout might occur, to identify streams likely to support wild brook trout under current and future climate scenarios.

The researchers then calculated the distance required to drive from the centers of 23 cities spread throughout the eastern brook trout range to the 10 nearest stream segments likely to have wild brook trout under current and future conditions. They published their study in a recent issue of Fisheries.

"Climate change is expected to result in widespread changes in species distributions for freshwater fish species. Although anglers and other resource users could be greatly affected by these predicted changes, changes are rarely reported in ways that can be easily understood by the general public," said Wagner, who is assistant unit leader of the Pennsylvania Cooperative Fish and Wildlife Research Unit at Penn State.

The effects of climate change on fish and wildlife are usually reported to the general public using summary metrics or maps designed to communicate concepts that are not normally encountered in everyday life, including changes in habitat suitability, range shifts, or increasing risks from disease or extreme events, according to Wagner. "Though these metrics are necessary, meaningful, and understood by scientists, many people lack the necessary training and background to readily understand them."

"Further, scientists and nonscientists alike may struggle to convert these metrics into a currency that directly affects day-to-day life. Climate science is a complex issue, and when we communicate potential responses of vegetation, fish and wildlife to nonscientists, creative thinking with respect to the currency of communication will facilitate discussions between scientists, policy makers and the public."

DeWeber, who was a doctoral student at Penn State when the research was conducted, noted that travel costs based on distance have been widely used to value ecosystem services such as angling under climate-change scenarios, but have not been used for communicating potential changes to the public, despite the intrinsic link to everyday life.

"Under current conditions, brook trout are predicted to occur in streams throughout the region, and average driving distances from cities to the nearest streams predicted to offer angling opportunities ranged from 4 to 87 miles. As a result of projected warming, driving distance to go fishing for wild brook trout was predicted to increase, on average, by almost 164 miles over the next 70 to 80 years."

For example, the driving route from Philadelphia to the nearest brook trout stream was predicted to cover 249 miles in a warmer future, much longer than the current 48 miles.

The lengths of trips from many northern cities, such as Bangor, Maine, were predicted to increase but were still relatively short in the future because nearby streams were still predicted to support brook trout under warmer conditions.

In contrast, anglers in southern cities, such as Cleveland, Tennessee, would experience dramatic increases in the lengths of trips because brook trout are predicted to be lost in surrounding areas.

Although anglers tend to be very dedicated, DeWeber pointed out, it is unlikely that many would drive great distances to fish very often due to cost, especially if those last remaining streams become popular and crowded. He believes that losses of wild brook trout populations and increased trip lengths would likely result in reduced resource use in many areas.

But he suggested that people are unlikely to be concerned about the potential effects of warming if they do not understand what may be coming. "Communicating species responses to climate change in everyday language could greatly increase the ability of resource users and other members of the general public to understand and relate to predicted changes," he said. "A clear understanding of potential changes might not lead to greater societal concern about species' responses, but it may enable people to make informed decisions."

Heavy Air Pollution In Beijing Awaits World Running Championships. The drifting smoke from forest fires sometimes makes it difficult for marathoner Heather Lieberg to take a deep breath during her afternoon training runs in the hills of <a href="https://www.bing.com/search?q=montana+map&amp;cvid=32baadfdb0ac483b8242d1d0c3196dca&amp;FORM=ANAB01&amp;PC=HCTS">Montana</a>.
Even on days when the local advisory lists the air quality as "unhealthy for sensitive groups," Lieberg is out there chugging away through the hazy and hot conditions.
No better way to acclimate her body to the heavy air pollution that awaits in Beijing for the world championships. Heavy Air Pollution In Beijing Awaits World Running Championships
"I've literally trained when there's ash falling on me, where they say `Do not go outside,'" said Lieberg, a 36-year-old from Helena. "My lungs are definitely ready."
Seven years after the Olympics sparked talk of a dramatic clean-up of heavy air pollution in Beijing, a milky haze still covers the city on most days and is expected to be there when the marathons take place - Saturday for the men, and Aug. 30 for the women.
According to a recent study conducted by physicists at the University of California, Berkeley, 1.6 million people die each year in China from heart, lung and stroke-related problems due to polluted air. The statistic is a reminder that while the Olympics may serve to shed light on a host city's environmental problems, they don't necessarily solve them.
With the 2022 Winter Olympics set to also take place in Beijing, the environment is likely to stay in the spotlight, in part because of plans to bring tons of artificial snow to the relatively dry mountains outside Beijing.
It's as true for Rio de Janeiro today as it was for Beijing in 2008, Athens in 2004, Sydney in 2000 or almost any other host, all of which have had their problems with air and/or water, said John Karamichas, author of the 2013 book "The Olympic Games and the Environment."
"All these issues were, in one way or another, addressed for the duration of the games," Karamichas said. "Environmental legacy will depend on the post-event political processes."
An expert from the World Health Organization, Martin Taylor, said government figures have shown some improvements in Beijing's air quality since the Olympics left town "but there is still some way to go before (it) meets international safe standards."
Competition conditions for the Olympic athletes have been at the forefront recently with the Rio Games less than a year away.
An analysis commissioned by The Associated Press found viruses running rampant in Rio's sewage-strewn water. The International Olympic Committee has made no plans to test for viruses, sticking with a plan to only monitor bacteria. Some swimmers have fallen ill after competing in the water, though the direct correlation between the water and the illness is difficult to make.
Running in heavily polluted air carries some health risk because of particulates that can clog up passageways and increased ozone that mainly bothers people with asthma. It can also affect finely tuned athletes who operate at maximum lung capacity. In 2008, the marathon world record holder, asthma sufferer Haile Gebrselassie, said he wouldn't run the race. "The pollution in China is a threat to my health," he said.
But he was an exception. And even though pollution readings distributed by the U.S. Embassy's Beijing Air Quality Monitor frequently shows the air quality in the "unhealthy" range, the races at world championships will go on.
Questions about if runners should wear masks for competition are resurfacing. Scientists think that would produce, at best, mixed results. The masks do filter out particulates but most elite runners are creatures of habit and not used to wearing them. Distance runner Galen Rupp won U.S. championships wearing a mask in 2011, but he had trained extensively with it, and it was used to filter out pollen, not pollution.
"One can't with a straight face say that it doesn't do anything," said Dr. Sverre Vedal, a health science professor at the University of Washington. "But one of the issues that comes up is the practicality of wearing a mask if you're performing."
Last October, the Beijing Marathon began with thousands of participants wearing masks. The air quality reading that day was considered hazardous, and a level at which the U.S. Embassy says everyone should avoid all outdoor exertion.
Big events such as the Olympics and world championships put authorities on timelines to mitigate the problems, at least temporarily.
For the track meet, local organizers are following a model nicknamed "APEC Blue" - a Chinese government program that produced blue skies last November for the Asia-Pacific Economic Cooperation summit.
This approach calls on nearby provinces to cut down on the amount of pollution drifting in from factories outside the city limits. Officials also will restrict the number of cars on the streets of Beijing starting Thursday, two days before the world championships begin. They took half the cars off the road each day starting a few weeks before the Olympics.
A handful of athletes the AP interviewed said they're heading to Beijing knowing they can't do much about the pollution.
"I'm running for only 12 seconds," American hurdler David Oliver said. "Now, if I were a marathoner, maybe I'd pay more attention."

Study: Dying Wildlife And Bigger Fires If Drought Continues. The carcasses of salmon, trout and more than a dozen other newly extinct native species lie in dry streambeds around California.
Exhausted firefighters in the Sierra Nevada battle some of the biggest wildfires they've ever seen. And in Central Valley farm towns, more and more mothers hear the squeal of empty pipes when they turn on water taps to cook dinner.Study: Dying Wildlife And Bigger Fires If Drought Continues
A new report by the Public Policy Institute of California non-profit think-tank paints that distressing picture of California for the next two years if the state's driest four years on record stretches further into the future.
Written by water and watershed experts working at the policy center, at the University of California, Davis, and elsewhere, the report urges California to do more now to deal with what researchers project to be the biggest drought crises of 2016 and 2017 - crashing wildlife populations, raging wildfires and more and more poor <a href="http://www.earth.com/news/rising-suicide-rates-rural-counties/">rural</a> communities running out of water entirely.
So far, of all the sectors dealing with the drought, <a href="https://www.bing.com/search?q=california&amp;cvid=959b5795b215418bb2b813f28e952351&amp;FORM=ANAB01&amp;PC=HCTS">California</a> cities are doing relatively well thanks to the lessons of past droughts, the report concludes. Meanwhile, farms have been able to turn to pumping well water to make up for having half as much surface water for irrigation as normal.
With California wildlife, by contrast, "we're really looking at widespread crisis" if the drought continues, Ellen Hanak, director of the think-tank's water policy center, said in an interview Wednesday.
California's fresh-water habitats and forests, along with their wildlife, have experienced the most severe impacts of the drought so far, the study concluded.
Lack of water means 18 species of native California fish, including most native salmon and steelhead trout, face an immediate threat of going extinct in the wild, the report said.
Greatly reduced water deliveries to bird refuges and rice fields - the flooding of which provides crucial habitat - means there is dangerously little room and food for the 5 million migratory birds that fly through the Central Valley each year and a high risk of deadly disease for the birds, the study said.
For California's environment, officials should be thinking more strategically about how best to use what water is left for wildlife, and preparing "conservation hatcheries" to safeguard native fish species that are on the verge of extinction in the wild, it said.
Hanak also called wildfires a tremendous risk as overgrown forests dry in the drought. Fire and forest agencies already are working to reduce the overgrowth that contributes to making those fires bigger and harder to control, researchers said.
After the environment, rural communities have been hardest-hit by the drought, the study said. As of last month, more than 2,000 domestic wells were reported to have gone dry, mostly in the Central Valley and Sierra Nevada. More than 100 small public-water systems around the state have been cited as needing emergency water supplies.California's fresh-water habitats and forests, along with their wildlife, have experienced the most severe impacts of the drought so far
State and federal efforts to help those communities have been increasing but remain stop-gap, the study concluded. It urges the state to do more to track areas in need of help and come up with longer-term water supplies to replace wells that have likely gone dry for good.

BP Oil Spill Settlement Money Found In Strange Places. Clusters of landlocked municipalities more than 100 miles from the Gulf Coast have secured millions of dollars in BP money through settlements designed to compensate local governments for lost tourism dollars and other economic damage from the company's 2010 oil spill, according to records obtained by The Associated Press.
This week, BP finished making approximately $687.4 million in settlement payments to 383 local government entities in the five Gulf states. Nearly $8 million of that money went to 32 government entities that are more than 100 miles from the coast, in places like the<a href="https://www.bing.com/search?q=mississippi&amp;cvid=a6dd128c0c76464cb2b2849ff061a493&amp;FORM=ANAB01&amp;PC=HCTS"> Mississippi</a> Delta and suburbs of central Alabama, the records show.BP Oil Spill Settlement Money Found In Strange Places
BP's well blowout off Louisiana's coast triggered a deadly explosion that killed 11 rig workers and spewed millions of gallons of oil into the Gulf of Mexico, staining beaches, killing wildlife and scaring away tourists.
The company agreed last month to pay up to $1 billion to resolve economic claims by local governments, but the settlement payouts have fallen well short of that maximum amount. The records obtained by the AP provide the most comprehensive accounting of where the money went and what types of government entities received shares.
The AP analyzed minimum distances from the center point of each city or town to the coastline to determine which locations were farther than 100 miles away from the coast.
Jackson, Mississippi, approximately 175 miles from the coast, received $1.3 million. Birmingham, Alabama, more than 200 miles from the coast, received $1 million.
Among the smaller cities receiving money is Ruleville, a Mississippi Delta city that landed $40,748. Ruleville, which is nearly 300 miles from the coast and has about 3,000 residents, said it lost revenue from sales taxes and other sources due to a drop in tourist travel after the spill. The city, perhaps best known as the hometown of civil rights activist Fannie Lou Hamer, is in an area that is a popular destination for blues music fans.
"Everybody in Mississippi suffered to varying degrees," said Danny Griffith, Ruleville's city attorney.
Irondale Mayor Tommy Joe Alexander - whose city in the <a href="http://www.earth.com/news/drinking-cocoa-can-make-your-brain-sharper-and-faster/">Birmingham</a> suburbs received a $57,225 settlement award - said a seafood shortage after BP's spill led to a decrease in sales tax generated by local restaurants.
"We're very fortunate that we did get something," he said. "There was an impact on the whole state."
BP's settlements with local governments are part of its broader $18.7 billion agreement with the five Gulf Coast states and the federal government. Larger portions of settlement money are dedicated to coastal restoration work. BP already has paid billions of dollars in compensation to Gulf Coast businesses and residents who claim the spill cost them money.
July 15 was the deadline for local governments to decide whether to accept the settlement offer, which could not be renegotiated. BP, which couldn't veto individual payments, accepted the package of settlements on July 27.
A modest "windfall" for several communities far from the coast must have been an afterthought for BP given the broader deal's high stakes, according to Ed Sherman, a Tulane University Law School professor emeritus and expert in complex litigation.
"It's not a great deal of money when you consider the total amount of the settlement," Sherman said.
Only a handful of local governments have publicly announced that they rejected a settlement offer. They are free to continue pursuing their claims, but may have to wait for a trial date if BP is unwilling to negotiate a separate deal.
Many local governments that sued BP over the spill enlisted help from private attorneys who handled their claims on a contingency basis, typically in exchange for at least 20 percent of the settlement amount.
Ike Gulas, an attorney who filed claims for several government entities in the Birmingham area, said officials from other local communities contacted him after the settlement was announced last month and were disappointed to learn it was too late to file their own claims.
"A lot of lawyers looked at it and didn't think there was a claim there, but we did," Gulas said.
Many communities sought significantly more than what they ultimately accepted. Bessemer, another Birmingham suburb, accepted a $310,392 settlement, even though city attorney Shan Paden said independent accountants pegged Bessemer's spill-related losses at roughly $590,000.
"The timing was bad," Paden said of the spill. "The general economy was in bad shape. We can show objectively that the revenues were down for that period of time."
The federal judge overseeing most of the spill-related litigation against BP appointed a panel of neutral parties, including former FBI director Louis Freeh and Lafayette-based attorney Patrick Juneau, to determine the amounts of each settlement offer. The formulas and criteria used by the panel members have not been publicly disclosed.
The panel made offers to each local government that met certain legal requirements. To qualify, each government entity had to formally present its Oil Pollution Act claim to BP and either file a lawsuit or submit a two-page claim form directly to the federal court in New Orleans.
The $687.4 million in payments doesn't include awards to local governments that resolved their BP claims before the broader settlement was announced on July 2.
Nearly $371 million - more than half of the total settlement money - was awarded to local governments in Louisiana. Approximately $210 million is going to local governments in Florida, where the tourism industry cratered in the spill's aftermath even though few places in the state ever felt any direct impact from BP's oil. Local governments in Texas are getting $39.9 million, while those in Mississippi are receiving $37.3 million. Local governments in Alabama are getting $28.8 million.
The bulk of the settlement money - which was paid by BP in lump sums and can be spent on anything - is going to city and county or parish governments along the coast. Nearly $157 million, almost one quarter of the total, is going to more than 50 public school districts. Law-enforcement agencies are receiving around $21 million. Airports are getting nearly $15 million. About $6 million is going to hospitals.
William Husfelt, schools superintendent in Bay County, Florida, said the spill led to losses in property and sales tax revenues that fund public schools across the state.
"It was a terrible time for it to happen. It was right after the recession," he said. "The budgets were cut. Pay raises were flat."
Henry Kelley, a spokesman for the Okaloosa County, Florida, public schools, said the school board hadn't yet decided how to use its $2 million settlement award.
"We're not flush with cash. If spent properly, this will make a big impact," he said.

This story has been corrected to indicate that 32 recipients, not 33, are more than 100 miles away from the coast, and that the amount of money going to those entities is nearly $8 million instead of nearly $8.2 million.

BP Oil Spill Settlement Money Found In Strange Places

BP Oil Spill Settlement Money Found In Strange Places. Clusters...

Western Wildfires Burning Unchecked Due To Lack Of Firefighters. This summer's massive western wildfires have strained resources to the point that<a href="https://www.bing.com/search?q=wildfire&amp;cvid=3d1e2b511a104aeaa6d8b0656bf735b0&amp;FORM=ANAB01&amp;PC=HCTS"> wildfire</a> managers are being forced to let some fires burn unchecked, and that has renewed a longstanding debate about whether it is better to fight a fire - or to sometimes just let it burn out.
Drought and heat have combined to make this one of the most active fire seasons in the Lower 48 in recent years. Nearly 29,000 firefighters are battling some 100 large blazes across the West, but it hasn't been enough. In northern Idaho, private citizens have even jumped on fire lines to help overwhelmed firefighters. Western Wildfires Burning Unchecked Due To Lack Of Firefighters
"What we're getting now are much more intense fires because of all those years of suppression," said John Freemuth, a Boise State University professor and a public lands expert. "Those kinds of intense fires are usually not allowed to burn."
But fire managers have little choice this year.
Some 11,000 square miles have burned so far. Most of that has been in Alaska, but an increase in fires in the Idaho, Oregon, Montana, Washington and California has caused competition for firefighting resources with some requests going unmet.
Some fires have simply been unstoppable. Steve Ellis, deputy director of the U.S. Bureau of Land Management, earlier this week flew over a 443-square-mile rangeland fire in southwest Idaho and said he could see where retardant bombers put in lines that the fire easily crossed.
"It's always tough when we get to this point where we have much more fire than we have resources," said John Segar, one of eight members on an interagency group based in Boise that decides how to deploy the nation's wildland firefighters. "The decisions are essentially triage decisions."
Segar, chief of Fire Management for the U.S. Fish and Wildlife Service, sits on the National Multi-Agency Coordination Group at the National Interagency Fire Center.
While there's been a longstanding debate about whether it's better to fight a fire or just let it burn out, Sager said conditions are so volatile right now that every current fire or new fire start is being attacked with the intent of putting it out if resources are available.
"It's just been too dry and too hot," he said. Letting fires burn "really hasn't been a consideration this year."
Freemuth said land managers have moved toward recognizing using fire as a tool to reduce fuels that lead to intense fires, particularly after the giant fires in Yellowstone National Park in the late 1980s.
"Having fire on the landscape in the right conditions has been accepted management now," Freemuth said.
But efforts to reduce the threat of fires have been hampered by a lack of money for prescribed burns or work to clear brush.
Some Western lawmakers, including Republican Sens. Mike Crapo and Jim Risch of Idaho and Democratic Sen. Ron Wyden of Oregon, have been pushing for letting firefighting agencies use dollars meant for natural disasters. Currently, agencies have been dipping into money set aside for fire prevention, such as prescribed burns.
"It's sort of an East-West issue where other members of Congress and other parts of the country don't get it because they don't see these kinds of fires," Freemuth said.
Even some <a href="http://www.earth.com/news/scientists-track-endangered-green-turtles-in-western-australia/">Western</a> residents don't want to allow beneficial fires to burn because of the smoke, he noted. "It's like two environmental values having to be reconciled - the need for the right kind of fire and the need for good air quality."
Arguments have also been made for decades that more logging to remove trees and grazing by livestock to mow down grasses could remove fuels that would otherwise burn.
"Those can be legitimate tools," Freemuth said. "But that gets to the question of what's the purpose of our federal lands. Other people are going to say the No. 1 purpose should be ecosystem health."
Segar said the fires this year will likely burn until a season-ending weather event with rain or snow arrives, which could be weeks.
"We have so much fire on the ground we don't have enough people to put them out," he said. "They'll go out at the end of the season."

July Was The Hottest Month Ever Recorded On Earth. Earth just keeps getting hotter. July was the planet's hottest month on record, smashing old marks, U.S. weather officials said.
And it's almost a dead certain lock that this year will beat last year as the warmest year on record, they said.
July's average temperature was 61.86 degrees <a href="http://www.earth.com/news/babbler-birds-are-shifting-their-behavior-in-the-wrong-direction/">Fahrenheit</a>, beating the previous global mark set in 1998 and 2010 by about one-seventh of a degree, according to figures released Thursday by the National Oceanic and Atmospheric Administration. That's a large margin for weather records, with previous monthly heat records broken by a 20th of a degree or less.
"It just reaffirms what we already know: that the Earth is warming," said NOAA climate scientist Jake Crouch. "The warming is accelerating and we're really seeing it this year."
NOAA records go back to 1880. Separate calculations by NASA and the Japanese weather agency also found July 2015 to be a record.
The first seven months of 2015 were the hottest January-to-July span on record, according to NOAA. The seven-month average temperature of 58.43 degrees is 1.53 degrees warmer than the 20th-century average and a sixth of a degree warmer than the old record set in 2010.
Given that the temperatures have already been so high already - especially the oceans, which are slow to cool - NOAA climate scientist Jessica Blunden said she is "99 percent certain" that 2015 will be the hottest on record for the globe. The oceans would have to cool dramatically to prevent it, and they are trending warmer, not cooler, she said.
Crouch, Blunden and other scientists outside of the government said these temperatures are caused by a combination of man-made climate change and a strong, near-record El Nino. An El Nino is a warming of the equatorial Pacific Ocean that alters weather worldwide for about a year.
The oceans drove the globe to record levels. Not only were the world's oceans the warmest they've been in July, but they were 1.35 degrees warmer than the 20th-century average.
The heat hit hard in much of Europe and the Middle East. It was the hottest July on record in Austria, where records go back to 1767. Parts of France had temperatures that were on average 7 degrees above normal and temperatures broke 100 in the Netherlands, which is a rarity. And an Iranian city had a heat index (the "feels like" temperature) of 165 degrees, which was still not quite record.
Nine of the 10 hottest months on record have happened since 2005, according to NOAA. Twenty-two of the 25 hottest months on record have occurred after the year 2000. The other three were in 1998 and 1997.
This shows that despite what climate change doubters say, there is no pause in warming since 1998, Blunden said.
It doesn't matter if a month or a year is No. 1 or No. 2 or No. 5 hottest on record, said University of Georgia climate scientist Marshall Shepherd.
"The records are getting attention but I worry the public will grow weary of reports of new records each month," Shepherd said in an email. "I am more concerned about how the Earth is starting to respond to the changes and the implications for my children."

BP Oil Spill Settlement Money Found In Strange Places. Clusters of landlocked municipalities more than 100 miles from the Gulf Coast have secured millions of dollars in BP money through settlements designed to compensate local governments for lost tourism dollars and other economic damage from the company's 2010 oil spill, according to records obtained by The Associated Press.
This week, BP finished making approximately $687.4 million in settlement payments to 383 local government entities in the five Gulf states. Nearly $8 million of that money went to 32 government entities that are more than 100 miles from the coast, in places like the Mississippi Delta and suburbs of central Alabama, the records show.BP Oil Spill Settlement Money Found In Strange Places
BP's well blowout off <a href="https://www.bing.com/search?q=Louisiana&amp;cvid=9a909e965da74bd1971484c6a6f29522&amp;FORM=ANAB01&amp;PC=HCTS">Louisiana's</a> coast triggered a deadly explosion that killed 11 rig workers and spewed millions of gallons of oil into the Gulf of Mexico, staining beaches, killing wildlife and scaring away tourists.
The company agreed last month to pay up to $1 billion to resolve economic claims by local governments, but the settlement payouts have fallen well short of that maximum amount. The records obtained by the AP provide the most comprehensive accounting of where the money went and what types of government entities received shares.
The AP analyzed minimum distances from the center point of each city or town to the coastline to determine which locations were farther than 100 miles away from the coast.
Jackson, Mississippi, approximately 175 miles from the coast, received $1.3 million. Birmingham, Alabama, more than 200 miles from the coast, received $1 million.
Among the smaller cities receiving money is Ruleville, a Mississippi Delta city that landed $40,748. Ruleville, which is nearly 300 miles from the coast and has about 3,000 residents, said it lost revenue from sales taxes and other sources due to a drop in tourist travel after the spill. The city, perhaps best known as the hometown of civil rights activist Fannie Lou Hamer, is in an area that is a popular destination for blues music fans.
"Everybody in Mississippi suffered to varying degrees," said Danny Griffith, Ruleville's city attorney.
Irondale Mayor Tommy Joe Alexander - whose city in the Birmingham suburbs received a $57,225 settlement award - said a seafood shortage after BP's spill led to a decrease in sales tax generated by local restaurants.

Earth just keeps getting hotter. July was the planet's hottest month...

1,800 Years Of Global Ocean Cooling Halted By Global Warming. Comprehensive analysis of ocean surface temperature data shows a cooling trend preceding the Industrial Revolution

Prior to the advent of human-caused global warming in the 19th century, the surface layer of Earth’s oceans had undergone 1,800 years of a steady cooling trend, according to a new study. During the latter half of this global ocean cooling period, the trend was most likely driven by large and frequent volcanic eruptions.1,800 Years Of Global Ocean Cooling Halted By Global Warming

An international team of researchers reported these findings in the August 17, 2015 issue of the journal Nature Geoscience. The study also indicates that the coolest temperatures occurred during the Little Ice Age—a period that spanned the 16th through 18th centuries and was known for cooler average temperatures over land.

The concurrence of cooling events on both land and sea suggests that a <a href="http://www.earth.com/news/the-window-to-avoid-dangerous-global-warming-is-narrowing/">global</a> cooling phenomenon was erased by subsequent human-caused global warming.

“Today, the Earth is warming about 20 times faster than it cooled during the past 1,800 years,” said Michael Evans, second author of the study and an associate professor in the University of Maryland’s Department of Geology and Earth System Science Interdisciplinary Center (ESSIC). “This study truly highlights the profound effects we are having on our climate today.”

Compared to the atmosphere, the oceans can absorb much more heat and trap it for longer periods of time. Thus the <a href="https://www.bing.com/search?q=ocean&amp;cvid=62049be582284d8ab101b0a5aaaea521&amp;FORM=ANAB01&amp;PC=HCTS">ocean</a> can buffer short-term changes in global temperature. But when events such as volcanic eruptions cluster together in a relatively short period of time, the temperature changes can become prolonged.

“Volcanic eruptions have a short-term cooling effect on the atmosphere, but our results showed that when volcanic eruptions occurred more frequently, there was long-term ocean cooling,” said lead author Helen McGregor, an Australian Research Council (ARC) Future Fellow at the University of Wollongong in Australia. “With this research, we now have new insight into the century-scale global sea-surface temperature variations that came before man-made greenhouse gas forcing.”

The scientists are the first to combine 57 previously published marine surface temperature reconstructions that cover all of the world’s oceans, from near-polar to tropical regions. The team compiled the data within 200-year brackets to observe long-term trends, and then compared the findings to land-based reconstructions, which revealed similar cooling trends.

“No matter how we divided the data set, the cooling trend stands out as a robust signal,” McGregor said.

To investigate the cause of the cooling trend, the researchers turned to climate models. They examined how sea-surface temperatures reacted to various “forcing” factors, such as changes in solar output, Earth’s orbit, land use, volcanic activity and greenhouse gases. Only volcanic events resulted in a cooling trend that matched the team’s real-world observations.

Understanding how forcing factors changed ocean temperatures in the past can open a window into future climate change.

“Model simulations by others have shown us that the oceans can impart a substantial delay in the warming of the surface climate,” said Evans, who is also the lead of the Ocean2k working group of the Past Global Changes (PAGES) program. “With much of the heat from global warming entering our oceans, recent ocean surface warming may foreshadow additional future warming, in the same way ocean cooling appeared as a long-term response to large and frequent volcanic events in recent centuries.”

“We are still learning how the oceans mediate climate variations,” Evans added. “Further work combining both observations and simulations of ocean climate will refine our understanding of the ocean's role in climate change.”

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air">Invisible threat in urban air</h2>



City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge">Disturbing connections emerge</h2>



Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.



<h2 class="wp-block-heading" id="h-timing-matters">Timing matters</h2>



The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns">Genetic vulnerability patterns</h2>



Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.



<h2 class="wp-block-heading" id="h-public-health-implications">Public health implications</h2>



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.



As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



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



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.



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



Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.



Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.



Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



<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>.

</div><figcaption class="wp-element-caption">Companies like MindStudio help companies train their employees to implement the latest AI Agent building platform.</figcaption></figure>



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

Wildlife tunnels save millions of amphibians

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

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



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



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

</div></figure>



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Today’s Video of the Day from the <a href="https://welcome.miami.edu/">University of Miami</a> Rosenstiel School of Marine and Atmospheric Science explores how changes in water temperatures have affected tiger shark habitats and movements in the North Atlantic Ocean. The study reveals that rising temperatures have caused the sharks to shift toward the poles over the past 40 years.



“Tiger shark annual migrations have expanded poleward, paralleling rising water temperatures,” explained study lead author Neil Hammerschlag. “These results have consequences for tiger shark conservation, since shifts in their movements outside of marine protected areas may leave them more vulnerable to commercial fishing.”



The researchers analyzed nine years of tracking data from satellite-tagged tiger sharks, combined with four decades of conventional tag and recapture data provided by National Oceanic and Atmospheric Administration (NOAA) Cooperative Shark Tagging Program.



The experts found that during the last decade of record heat, for every one-degree Celsius increase in water temperatures, tiger sharks migrated further poleward by over 400 kilometers. They also migrated two weeks earlier than usual to waters off the northeastern coast of the United States.



“Given their role as apex predators, these changes to tiger shark movements may alter predator-prey interactions, leading to ecological imbalances, and more frequent encounters with humans,” concluded Professor Hammerschlag.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> is focused on the melt ponds that emerge during the spring and summer on the Greenland Ice Sheet, which is the largest ice mass in the northern hemisphere.



"Melt ponds are vast pools of open water that form on both sea ice and ice sheets and are visible as turquoise-blue pools of water in this Copernicus Sentinel-2 image," says ESA.



"When snow and ice melts atop glaciers, water flows in channels and streams and collects in depressions on the surface. These melt ponds can speed up the melting of the surrounding ice since they greatly reduce the ice’s ability to reflect sunlight."



"This can create a positive feedback where an increasing number of melt ponds absorb more heat which causes ice cover to melt even faster."



According to ESA, Greenland has been hit with a late-season heatwave that began in early September. This caused the type of melt event that usually occurs in the middle of summer.



"In a recent paper published in Nature Climate Change, scientists found that major sea-level rise from the melting of the Greenland ice cap is now ‘inevitable’ even if the burning of fossil fuels were to halt overnight," says ESA. "Using satellite observations of Greenland ice loss and ice cap from 2000 to 2019, the team found the losses will lead to a minimum rise of 27 cm regardless of climate change."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes how Earth is unique in our solar system for its ability to sustain liquid water on its surface. But now, the water cycle is shifting as the climate warms, and scientists must find ways to predict how these changes will affect water availability.



Overall, 96 percent of Earth's water is saltwater, and nearly all of freshwater is found in ice and groundwater. These sources of water are linked as it passes through solid, liquid and gas phases.



In a warmer climate, the water cycle will be transformed. It will be easier for water to evaporate and form clouds, and storms will become more frequent and intense. Some regions will get too much water, while others will be left without enough water. In addition, soil moisture will be lost - which threatens food security.



Scientists are using satellite data from over the last 40 years to track changes that are happening in the water cycle. This will ultimately help us prepare for extreme events and better manage our water resources, according to ESA.

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard Space Flight Center</a> features images of Saturn from NASA’s Hubble Space Telescope. The photographs capture the start of the mysterious "spoke season" on Saturn - when unexplained features appear on its rings. 



According to NASA, both the cause of the spokes and their seasonal variability have yet to be fully explained by planetary scientists.



"Like Earth, Saturn is tilted on its axis and therefore has four seasons, though because of Saturn's much larger orbit, each season lasts approximately seven Earth years. Equinox occurs when the rings are tilted edge-on to the Sun," explains NASA.



"The spokes disappear when it is near summer or winter solstice on Saturn. (When the Sun appears to reach either its highest or lowest latitude in the northern or southern hemisphere of a planet.) As the autumnal equinox of Saturn's northern hemisphere on May 6, 2025, draws near, the spokes are expected to become increasingly prominent and observable."



Experts believe that the spokes may be a product of the planet's variable magnetic field. When magnetic fields interact with solar wind, an electrically charged environment is created. This phenomenon is visible on Earth as the northern lights.&nbsp;



"Scientists think that the smallest, dust-sized icy ring particles can become charged as well, which temporarily levitates those particles above the rest of the larger icy particles and boulders in the rings," says NASA.



The spokes were first observed in the early 1980s by NASA's Voyager mission. Depending on the angle of the rings, the spokes can appear dark or light.



"Thanks to Hubble's OPAL program, which is building an archive of data on the outer solar system planets, we will have longer dedicated time to study Saturn’s spokes this season than ever before," said NASA senior planetary scientist Amy Simon, head of the Hubble Outer Planet Atmospheres Legacy (OPAL) program.



"Despite years of excellent observations by the Cassini mission, the precise beginning and duration of the spoke season is still unpredictable, rather like predicting the first storm during hurricane season."
