<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

Corals Also Need A Balanced Diet. Researchers examine nutrient enrichment and bleaching resilience in Red Sea corals

A new study found that a nutrient-rich, balanced diet is beneficial to corals during stressful thermal events. The research led by scientists at the University of <a href="https://www.bing.com/search?q=flordia&amp;cvid=d9cf3f84713b48dfa49f365baf7e6659&amp;FORM=ANAB01&amp;PC=HCTS">Miami</a> (UM) Rosenstiel School of Marine and Atmospheric Science and the Centre Scientifique de Monaco concluded that the particular nutrient balance in seawater is what matters most.Corals Also Need A Balanced Diet

To test which nutrients were more beneficial to corals during elevated temperature conditions, the scientists fed them two types - inorganic nutrients of <a href="http://www.earth.com/news/scientists-identify-molecular-link-between-nitrogen-and-plant-growth/">nitrogen</a> and phosphorus commonly found in the ocean as a result of fertilizers and sewage runoff, and organic nutrients of zooplankton, tiny animals in the ocean that coral are known to feed on.

The research team placed specimens of the yellow scroll coral, Turbinaria reniformis, collected from the Red Sea in separate seawater tanks with varying temperature and nutrients. The corals were subjected to two different inorganic nutrient enrichment scenarios - increased nitrogen only or increased nitrogen and phosphorus at varying temperatures - 25 degrees Celsius to represent normal temperature conditions and 30 degrees Celsius to represent thermal stress conditions. Some of the corals also received organic nutrient enrichment of tiny ocean animals called zooplankton during the laboratory experiment. All of the corals were then returned to normal temperature conditions to examine their recovery.

"We found that the coral's resilience to thermal stress totally depends on the kind of inorganic enrichment - if it's 'balanced' or not," said Erica Towle, an alumna of the UM Rosenstiel School.

The researchers found that excess nitrogen alone and zooplankton made high-temperature bleaching events worse. While excess nitrogen in combination with extra phosphorus and zooplankton afford the coral resilience to bleaching. This study is one of the first to assess the three-way interaction between the two types of nutrient enrichment and thermal stress on coral health.

The UM Rosenstiel School research team published a previous study in 2015 that showed the critically endangered Staghorn coral may benefit from supplemental nutrition to mitigate the adverse impacts of global climate change. The results revealed that temperature, CO2 and feeding each had significant effects on the coral's growth rate. That study was the first to document that an endangered coral species, which was once found widely throughout South Florida and the Caribbean, can buffer the effects of increased CO2 in the ocean by increasing feeding rates.

"Excess nutrients from land sources and thermal stress will likely occur in concert in the future so it's important to assess them together," said Towle. "Incorporating nutrient levels in thermal bleaching models will likely be very important for coral reef managers in the future as ocean waters warm."

Alaska Seeks Federal Funds To Relocate Newtok Village. One of Alaska's most eroded coastal Native villages is being eyed as a possible national model for relocating whole communities whose futures are threatened by natural disasters escalated by climate change.
The state is hoping to kick-start a mass exodus from the tiny Newtok village through a national competition for states and local governments vying for a slice of nearly $1 billion in grants to be awarded by the U.S. Department of Housing and Urban Development. HUD's National Disaster Resilience Competition is billed as an effort addressing <a href="https://www.bing.com/search?q=climate+change&amp;cvid=983b530af01d4e5e9dd2ad04ec4c0ef9&amp;FORM=ANAB01&amp;PC=HCTS">climate change</a> and extreme weather. Alaska Seeks Federal Funds To Relocate Newtok Village
If successful, Alaska officials are proposing that $62.6 million of the funds be used for relocation costs, including money for infrastructure and money to allow 62 families from Newtok to establish new homes at the chosen relocation site on higher ground 9 miles away. In the draft proposal publicly released Friday, state officials also are seeking a total of $162.4 million for three other vulnerable villages - Emmonak, Galena and Teller - with extensive storm damage in recent years.
But officials acknowledge that competing for the funding unused by Hurricane Sandy victims won't be easy. <a href="http://www.earth.com/news/alaskas-barry-glacier-could-trigger-a-catastrophic-tsunami/">Alaska</a> is among 40 finalists for the funds, including Hurricane Katrina-ravaged New Orleans. Still, Alaska officials are hoping their proposal catches the eye of federal officials.
"We think we have a very compelling story to tell," said Sally Russell Cox, a state planner who worked on the competition entry.
The release of Alaska's proposal opens a 15-day public comment period before the final contest submission is due to HUD Oct. 27. Alaska Seeks Federal Funds To Relocate Newtok Village
President Barack Obama, in his recent three-day visit to the state, focused almost entirely on climate change and how temperatures are rising faster in Alaska than anywhere else, already threatening entire communities.
Newtok is the only one of Alaska's multiple imperiled communities that has begun a physical move. The Yup'ik Eskimo community of about 380 shepherded various multiagency projects including construction of several homes and the beginning of an evacuation community center, which would be completed with nearly $5.5 million sought through the HUD competition. A tribal power dispute, however, stalled relocation efforts for about two years until a federal appeals panel sided with the new village leaders last month.
Oblivious to village politics, the raging Ninglick River is steadily inching toward homes, gobbling up as much as 75 feet of riverbank a year. Melting permafrost is sinking and knocking homes and village boardwalks out of alignment. Officials estimate Newtok, nearly 500 miles west of Anchorage, has until 2017 until erosion is expected to reach the school.
Villagers believe they're living on borrowed time, and they are actively lobbying for funding wherever they can find it. Village relocation coordinator Romy Cadiente is in Washington, D.C., this week to gather support by meeting with officials, including Alaska's congressional delegation or their representatives. The village is also trying to obtain funding for some homes for the new site through the U.S. Federal Emergency Management Agency, or FEMA, and is working with the Cold Climate Housing Research Center in Fairbanks on plans to build a high-efficiency home at the current site as a demonstration model.
"We're trying to really focus on how to get this village out of there," Cadiente said in a phone interview Wednesday. "That shore is not going to grow back."

Analysis: Volkswagen Pollution Cheating Killed Dozens Each Year. Volkswagen pollution chicanery has not just been victimless tinkering, killing between five and 20 people in the United States annually in recent years, according to an Associated Press statistical and computer analysis.
The software that the company admitted using to get around government emissions limits allowed VWs to spew enough pollution to kill somewhere between 16 and 94 deaths over seven years, with the annual count increasing more recently as more of the <a href="http://www.earth.com/news/bacteria-cold-green-detergents/">diesels</a> were on the road. The total cost has been well over $100 million.Analysis: Volkswagen Pollution Cheating Killed Dozens Each Year
That's just in the United States. It's likely far deadlier and costlier in Europe, where more VW diesels were sold, engineers said. Scientists and experts said the death toll in Europe could be as high as hundreds each year, though they caution that it is hard to take American health and air quality computer models and translate them to a more densely populated Europe.
"Statistically, we can't point out who died because of this policy, but some people have died or likely died as a result of this," said Carnegie Mellon environmental engineer professor Peter Adams. He calculates the cost of air pollution with a sophisticated computer model that he and the AP used in its analysis.
Computer software allowed VW diesel cars to spew between 10 to 40 times more nitrogen oxides (NOx) than allowed by regulation, making this "clearly a concern for air quality and public health," said Janet McCabe, acting air quality chief for the U.S. Environmental Protection Agency.
Nitrogen oxides mostly form smog - that murky, dirty air that makes it hard to see and for some people to breathe - but also amplify a deadlier, larger problem: tiny particles of soot. Numerous medical studies show those tiny particles cause about 50,000 deaths a year in the United States, mostly from heart problems.
Nitrogen oxides can travel hundreds of miles, so pollution spewed in Pittsburgh can be felt on the East Coast, Adams said.
Experts calculate how much pollution costs society by looking at the value of lost lives. In this case, Adams and other said the lost lives - valued at $8.6 million apiece - overwhelm other costs such as lost work days or hospital costs. The overall annual cost of the extra pollutants from the VW diesels ranged from $40 million to $170 million, environmental engineering professors calculated.
"Even the small increase in NOx from VW diesel emissions is likely to have worsened pollution along the roadways where they have traveled, and affected the lives of hundreds of thousands of people," said Dan Greenbaum, president of the Health Effects Institute in Boston.
"To say millions of people of people are breathing poor air as the result of that is not off the mark," said Greenbaum, who runs the institute that is funded by both the EPA and the auto industry to serve as an independent arbiter of the science.
Representatives of VW did not respond to AP request for comment.
These calculations should be put in context of air that is getting dramatically cleaner in the United States, experts said. Also, the deaths from extra pollution are dwarfed by the 35,000 people in the U.S. a year who die in auto accidents and are closer to the annual U.S. death toll of spider or snake bites.
The AP calculated how much pollution was spewed year by year, starting with that broad 10 times to 40 times emissions level estimate from the EPA, then factoring in mileage and car number totals from EPA, the car company and Kelley Blue Book.
The results show an upper and lower limit of extra nitrogen oxides pollution allowed by VW's subterfuge. The AP took those figures to scientists who previously created a sophisticated computer program that looks at air movement and numerous epidemiological studies on the health effects of pollutants. The result was a rough estimate on deaths and costs to society based on a certain amount of pollution triggering each death.
The EPA has its own open source computer model that calculates death and social costs of emissions, roughly finding it takes nearly 1,300 tons of nitrogen oxides to cause one death. Using that calculation and AP's emission totals, the total death figures over the past seven years range from 12 to 69, slightly lower than the AP calculations.
The AP ran its calculations and results by more than a dozen experts in emissions, risk and public health. They all confirmed the calculations and results seemed right. One scientist had even done a statistical analysis on his own and came independently to the same conclusion. The experts were mostly university professors or from research institutes. They were not environmental advocates or representatives of auto companies.
But engineers caution that these figures come with many caveats and are ballpark estimates. They rely on many assumptions and a range of potential emissions per car. Air pollution impacts on people are usually calculated on a local level because that's where it is felt, and it changes from place to place. But these calculations were broadened to a national level, which adds more uncertainty.
The computer simulation that made the death calculations use conservative medical studies as their baseline. Other epidemiological studies would more than double the deaths and health costs, said Adams and model co-creator Jinhyok Heo of Cornell University.
Chris Frey, an engineering professor at North Carolina State University, has been testing the VW diesels in real world conditions, driving more than 100 miles with monitors in the car tailpipes. He found pollution 10 times higher than the federal standard, and noticed that the worst pollution came as he got on to highways and in stop-and-go traffic. Those less desirable areas are where poorer people live, Adams and Greenbaum said.
Since 2008, VW sold more than 10 million VW diesel cars in Europe, compared with less than half a million in the United States. In Europe, the population is more densely packed in urban areas, making them more vulnerable to added air pollution, several experts said.
"Assuming most of the cars are in Europe, it's pretty simple to estimate that it could go as high as hundreds," said Robert Rohde, a physicist and lead scientist at the Berkeley Earth team that has estimated death tolls of air pollution in the past.

BP Deepwater Horizon Gulf Oil Spill Settlement Finalized. The Justice Department and five states have finalized a settlement of more than $20 billion arising from the 2010 Deepwater Horizon gulf oil spill in the Gulf of Mexico.
The deal announced Monday resolves all civil claims against BP and ends five years of legal fighting over the nearly 134 million-gallon spill.
"BP is receiving the punishment it deserves, while also providing critical compensation for the injuries it caused to the environment and the economy of the Gulf region," Attorney General Loretta Lynch said at a Justice Department news conference. "The steep penalty should inspire BP and its peers to take every measure necessary to ensure that nothing like this can ever happen again."BP Deepwater Horizon Gulf <a href="http://www.earth.com/news/warming-of-2c-would-unleash-230-billions-tons-of-soil-carbon/">Oil</a> Spill Settlement Finalized

Feds: Difficult To Prosecute Companies Over Migratory Bird Deaths. Companies accused of causing migratory bird deaths may be harder to successfully prosecute after a federal appeals court recently ruled that a century-old wildlife protection law only applies if the killing is intentional.
The decision by the 5th U.S. Circuit Court of Appeals runs contrary to two other federal courts' interpretations of the 1918 Migratory Bird Treaty Act and could save companies that operate wind farms, power transmission lines and other methods of energy production millions in research - at the risk of more bird deaths.
"If you have a dead migratory bird, you have a violation. Doesn't matter how, why or when; that's historically been the government's interpretation," said Barry Hartman of K&amp;L Gates, a Washington law firm that represents Duke Energy Corp. "And what the court is saying is that interpretation doesn't extend to unintentional takes." Feds: Difficult To Prosecute Companies Over Migratory Bird Deaths
The U.S. <a href="https://www.bing.com/search?q=fish&amp;cvid=0ae78e786ab3416dbc210e9377cbe290&amp;FORM=ANAB01&amp;PC=HCTS">Fish</a> and Wildlife Service has maintained that no intent is required to violate the law, which makes it illegal to "pursue, hunt, take, capture" or "kill" more than 1,000 bird species. But companies have long claimed they should not be held responsible for actions that incidentally cause deaths - up to about a half-million annually by wind turbines alone, the federal agency says.
The nation's appellate courts have starkly different interpretations of the law, resulting in an uneven enforcement across the country, with companies in some <a href="http://www.earth.com/news/earth-could-be-powered-entirely-by-renewable-energy/">energy</a>-rich states facing a narrower liability toward migratory birds than operations in other regions.
In the Sept. 4 ruling, the 5th Circuit said a U.S. District Court was wrong to convict and levy a $2 million fine against Citgo Petroleum Corp. for the deaths of at least 35 protected birds that flew into two large, open-top petroleum tanks in 2003 in Corpus Christi. In overturning the lower court's decision, the 5th Circuit agreed with Citgo that the statute was misinterpreted as covering unintentional bird kills.
The ruling agrees with decisions from the 8th and 9th Circuits that hold the law only applies to the intentional killing of birds, but contrasts with two other circuit rulings - one of which upheld misdemeanor convictions of two Kansas oil rig operators after dead birds were found trapped in oil-treatment vessels.
"It was a very easy charge for the government to bring" without having to prove intent, said Benjamin Cowan, a Houston attorney who represents traditional and renewable energy companies. "They won't be able to do that anymore."
The U.S. Fish and Wildlife Service, which has also used the bird act to regulate wind energy, and the Department of Justice are reviewing the 5th Circuit ruling before deciding whether to appeal to the U.S. Supreme Court, service spokeswoman Laury Parramore said. She added they may also ask the appeals court to reconsider.
The federal service is considering adding new regulations to mitigate bird deaths from energy production.
Since 2013, the Department of Justice has prosecuted two energy companies whose Wyoming wind turbines killed migratory birds, as well as several oil and gas companies in North Dakota whose wastewater pits became death traps for ducks. In 2014, Duke Energy Corp. was sentenced to $1 million in fines and five years' probation and ordered to develop a mitigation strategy for bird deaths at wind farms.
Environmental groups say the ruling by the 5th Circuit - which covers the energy-producing states of Texas, Louisiana and Mississippi - weakens the law's intent in some of the country's most crucial bird habitats; Texas leads the nation in wind energy production. The groups also say the ruling threatens the integrity of treaties signed with Great Britain, Canada, Japan, Mexico and Russia.
The first of these, signed by the U.S. and Canada in 1916, was enacted in an era when many bird species were threatened by the commercial trade of birds and feathers and was intended to protect against the "indiscriminate slaughter" of migratory birds.
Eric Glitzenstein, an attorney who represents the American Bird Conservancy, called the ruling "an extraordinarily narrow" interpretation of the statute.
"Ignoring the greatest threats to migratory bird populations from inherently hazardous industrial activities is really a setback to our commitment to migratory birds in a serious and unfortunate way," he said.

BP Deepwater Horizon Gulf Oil Spill Settlement Finalized. The Justice Department and five states have finalized a settlement of more than $20 billion arising from the 2010 Deepwater Horizon gulf oil spill in the Gulf of Mexico.
The deal announced Monday resolves all <a href="https://www.bing.com/search?q=civil&amp;cvid=5cf3ebea38554c12b31c1db97a3a91a7&amp;FORM=ANAB01&amp;PC=HCTS">civil</a> claims against BP and ends five years of legal fighting over the nearly 134 million-gallon spill.
"BP is receiving the punishment it deserves, while also providing critical compensation for the injuries it caused to the environment and the economy of the <a href="http://www.earth.com/image/city-lights-surround-the-persian-gulf/">Gulf</a> region," Attorney General Loretta Lynch said at a Justice Department news conference. "The steep penalty should inspire BP and its peers to take every measure necessary to ensure that nothing like this can ever happen again."
The settlement finalizes an agreement first announced in July. The Deepwater Horizon oil spill was an industrial disaster that began on April 20, 2010, in the Gulf of Mexico on the BP-operated Macondo Prospect, considered to be the largest marine oil spill in the history of the petroleum industry and estimated to be 8 percent to 31 percent larger in volume than the previous largest, the Ixtoc I oil spill, also in the Gulf o…

Among other requirements, BP will be forced to pay $5.5 billion in Clean Water Act penalties and nearly $5 billion to five Gulf states: Alabama, Florida, Louisiana, Mississippi and Texas. BP Deepwater Horizon Gulf Oil Spill Settlement Finalized
The spill followed the April 2010 explosion on an offshore rig that killed 11 workers. BP earlier settled with people and businesses harmed by the spill, a deal that's so far resulted in $5.84 billion in payouts.

Obama Designates Two New National Marine Sanctuaries. President Barack Obama declared new marine sanctuaries in Lake Michigan and the tidal waters of Maryland on Monday, while Chile blocked off more than 200,000 square miles of the <a href="https://www.bing.com/search?q=Pacific+Ocean&amp;cvid=f37903bcfa0e47ad93b9fbce37e2246e&amp;FORM=ANAB01&amp;PC=HCTS">Pacific Ocean</a> near the world-famous Easter Island from commercial fishing and oil and gas exploration.
The announcements came as top officials, including U.S. Secretary of State John Kerry, attended an international conference on marine protection in the Chilean port city of Valparaiso. Several nations also outlined plans for tracing seafood imports to combat overfishing and stemming increased pollution in the ocean. Obama Designates Two New National Marine Sanctuaries
The new protected waters in the <a href="http://www.earth.com/image/severe-fire-threat-continues-in-the-western-united-states/">United States</a> are the first to be designated as such in 15 years, the White House said in a statement.
The 875-square mile area of Wisconsin's Lake Michigan extends from Port Washington to Two Rivers, containing a collection of 39 known shipwrecks. Fifteen are listed on the National Register of Historic Places.
The Mallows Bay-Potomac River in Maryland encompasses a 14-square mile area of the tidal Potomac River next to Charles County. Nearly 200 vessels, some dating back to the Revolutionary War, are found in the largely undeveloped area that provides habitat for endangered species of wildlife and fish.
The actions are the latest in a series of environmental steps by Obama, who last year set aside some 400,000 square miles of the central Pacific Ocean from commercial fishing, deep sea mining and other forms of resource extraction. The Pacific Remote Islands Marine National Monument is now the largest marine reserve in the world.
In a videotaped message to conference participants, Obama recalled his childhood in Hawaii and Indonesia and said he always maintained "a special love for the ocean."
"Our economies, our livelihoods and our food all depend on our oceans," he said, "and yet we know that our actions are changing them. Greenhouse gas emissions are making our seas warmer and more acidic. Marine pollution harms fish and wildlife, affecting the entire food chain. Illegal fishing depletes the world's fisheries."
Obama said he would seek to protect more American waters in the coming months.
Chile made its own ambitious declaration, cordoning off a vast expanse of the South Pacific Ocean.
President Michelle Bachelet said the new marine park would protect the ancestral species of Rapa Nui, the name used by the native Polynesians of Easter Island, which is celebrated for its hundreds of human statues carved out of volcanic rock. She was joined by representatives of the island, who clapped their hands and sang after the announcement was made.
Bachelet called it the third-largest protected marine zone worldwide.
Britain, Gabon, Kiribati, New Zealand and Palau have taken steps as well to protect sections of the sea in recent months.
The "Our Ocean" conference also targeted marine pollution resulting from discarded plastics and increasing levels of ocean acidification, which damages coral reefs and shellfish populations. Such concerns are shared by the U.S., which imports 90 percent of the fish it consumes, and Chile, whose coastline of almost 2,500 miles is vital to the economy.
To address overfishing, the Obama administration announced a global initiative, "Sea Scout," to identify unregulated and unreported activity, and help prosecute illegal fishing organizations. The U.S. National Oceanic and Atmospheric Administration is expanding a program for detecting boats that use lights to attract fishery catch at night and will implement it in Indonesia, the Philippines and three other countries next year.
The "traceability" initiative is supposed to start for the most commonly exported fish species such as tuna, cod, shrimp and crab in September 2016. It would apply to all fish a year later and is designed to provide a full accounting of where exporters are getting their catch and whether they are operating in a sustainable manner. Anyone who wants to export fish to the United States would have to adhere to the conditions. The program needs final approval from the U.S. Senate and several additional countries before entering into force.
"There is literally too much money chasing too much fish," Kerry told the conference. A third of the world's fish stocks are over-exploited, he said, calling overfishing a $10 billion-a-year industry.

Feds: Difficult To Prosecute Companies Over Migratory Bird Deaths. Companies accused of causing migratory bird deaths may be harder to successfully prosecute after a federal appeals court recently ruled that a century-old wildlife protection law only applies if the killing is intentional.
The decision by the 5th U.S. Circuit Court of Appeals runs contrary to two other federal courts' interpretations of the 1918 Migratory <a href="http://www.earth.com/earthpedia-articles/save-the-baby-kiwi-birds/">Bird</a> Treaty Act and could save companies that operate wind farms, power transmission lines and other methods of energy production millions in research - at the risk of more bird deaths.
"If you have a dead migratory bird, you have a violation. Doesn't matter how, why or when; that's historically been the government's interpretation," said Barry Hartman of K&amp;L Gates, a Washington law firm that represents <a href="https://www.bing.com/search?q=duke+energy&amp;cvid=0fb30bf47abc469cba6f66da0b2aa8fe&amp;FORM=ANAB01&amp;PC=HCTS">Duke Energy</a> Corp. "And what the court is saying is that interpretation doesn't extend to unintentional takes."
The U.S. Fish and Wildlife Service has maintained that no intent is required to violate the law, which makes it illegal to "pursue, hunt, take, capture" or "kill" more than 1,000 bird species. But companies have long claimed they should not be held responsible for actions that incidentally cause deaths - up to about a half-million annually by wind turbines alone, the federal agency says.

Volkswagen Emission Testing

Volkswagen Pollution Testing Center Under Scrutiny After Scandal. When Volkswagen opened its gleaming pollution testing center near the California coast, a top executive from the German automaker helped snip the blue ribbon and joined a tour of a lab so advanced that VW would brag the air inside was cleaner than in the surrounding strawberry fields.
Three years later, with VW admitting that it manipulated emissions results in 482,000 U.S. diesel vehicles to make them seem more environmentally friendly, questions are swirling around Volkswagen's only test center in <a href="https://www.bing.com/search?q=north+america&amp;cvid=ec97ef97f27a477c96c4ca8936edaed1&amp;FORM=ANAB01&amp;PC=HCTS">North America</a>. Was anyone at the facility complicit in the scheme? Or were VW's own testers unaware of the deception like so many others?
The center in Oxnard, about 60 miles northwest of Los Angeles, was built with the help of a $10 million, tax-exempt public bond and opened in 2012.


[caption id="attachment_2384940" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/10/05120204/volkswagen-america-headquarters_1big_ap.jpg"><img class="size-thumbnail wp-image-2384940" src="http://cff1.greenatom.net/uploads/2015/10/05120204/volkswagen-america-headquarters_1big_ap-150x150.jpg" alt="Volkswagens only test center in North America in Oxnard, Calif." width="150" height="150" /></a> Volkswagens only test center in North America in Oxnard, Calif.[/caption]
Volkswagen saw the facility as key to its multibillion-dollar U.S. growth strategy, partly because vehicles would have the selling point of meeting the nation's strictest emissions standards. At the facility, VW runs cars through a battery of tests to check whether they're polluting as little as advertised.
While no evidence has surfaced that Oxnard played a role in the fraud, the test center is sure to attract interest from government investigators and private attorneys lining up to sue VW.
"That would be one of the top facilities on my list to get inside of, whether through a subpoena or a search warrant," said William Carter, a former federal prosecutor in Los Angeles who specialized in environmental crimes. "You'd want to explore what's there."
Carter said that investigators would want to know whether anyone in Oxnard knew about the "defeat devices" that Volkswagen has acknowledged installing on models from 2009 through 2015. The "device" was code in engine software that cheated diesel car emissions tests in the U.S.; 11 million engines worldwide contained the software. The scandal forced out VW's CEO and could lead to $18 billion in U.S. fines, an avalanche of lawsuits and criminal prosecutions both here and abroad.
California has launched its own criminal probe, but the state Attorney General's office would not say if Oxnard was a focus. A U.S. Justice Department spokesman said prosecutors are working closely with U.S. Environmental Protection Agency investigators but declined to say more.
Two Southern California law firms have cited the center in lawsuits against VW.
"I'm dying to know if they were doing anything in that facility" related to the defeat device, said attorney Graham LippSmith, who is seeking damages for fraud and negligence in federal court in Los Angeles on behalf of VW diesel owners in California.


[caption id="attachment_2384939" align="alignleft" width="150"]<a href="http://cff1.greenatom.net/uploads/2015/10/05120202/volkswagen-pollution-testing-center_2big_ap.jpg"><img class="size-thumbnail wp-image-2384939" src="http://cff1.greenatom.net/uploads/2015/10/05120202/volkswagen-pollution-testing-center_2big_ap-150x150.jpg" alt="Volkswagen Passat with a diesel engine is evaluated" width="150" height="150" /></a> Volkswagen Passat with a diesel engine is evaluated[/caption]
Volkswagen declined to answer questions about what it calls Test Center California, instead providing a fact sheet first distributed at the 2012 opening attended by local dignitaries and VW officials. It denied a tour request, and security escorted out an Associated Press reporter who visited.
California officials who began investigating discrepancies in VW's diesel emissions months ago are familiar with the test center. The California Air Resources Board, in charge of enforcing the state's tough emissions standards, has likely received test results from the center but spokesman John Swanton could not be sure and would not say whether they included the 2009 to 2015 diesel models in question. Volkswagen Pollution Testing Center Under Scrutiny After Scandal
In recent weeks, agency staff visited Oxnard for ideas about how to upgrade their own aging emissions test center in El Monte, about 80 miles away, according to Swanton. The visit came while state and federal regulators were pressing VW to explain emissions test discrepancies but was not part of the investigation, he said.
The agency has researched other automaker test labs in California for ideas and was interested in the VW facility's top-notch environmental design, which includes rooftop solar paneling that provides one-third of its electricity.
And the agency is currently collaborating with VW to test emissions from a diesel research vehicle outside the lab. Air Resources Board engineers have been driving a red VW Golf up and down the coast to Oxnard, taking pollution readings using equipment strapped onto the back. The idea is to test ideas that VW is considering for a possible future diesel model, Swanton said.
Paperwork submitted to the City Council in 2010 as part of the approval process for a $10 million California Economic Development Authority tax-exempt bond to build the $27 million center said it would include "sophisticated emission-testing equipment" as part of VW's research to develop ultra-low emission vehicles, including diesel. VW came to Oxnard to replace a smaller, older facility nearby.
Civic leaders in Oxnard received a tour in 2012 that focused on how the precision lab assesses engine performance and its impact on emissions, said Steven Kinney, former president of the Economic Development Corporation of Oxnard.
The floors were so clean you could eat off them, Kinney said. He peered into a climate-controlled chamber where engineers could simulate sub-zero temperatures or desert conditions and saw cars undergoing emissions testing on treadmills.
At the Oxnard facility, and those like it that other automakers have in Southern California, cars would typically be several years old - tested for how they are performing as they age. Testing to certify that a new model meets U.S. and California emissions standards is typically done at an automaker's headquarters.
"They were proud of the fact that the air inside the facility was cleaner than the ambient air," he recalled.
Now, Kinney is left with questions: "How are they going to react to this? How much are they going to now open up the facility to broader public scrutiny?"

<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.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

<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.

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."
