Plastic may not always float where we expect it. The ocean’s surface might look clean in some places, but far beneath the waves, a different story is unfolding. 



In the southeastern Mediterranean, the deep seafloor is turning into a massive storage ground for plastic packaging, especially bags. A new study shows how this <a href="https://www.earth.com/news/large-retailers-are-replacing-plastic-bags-with-eco-friendly-paper-bags/">waste</a> ends up thousands of feet below the surface, and the answer isn’t as simple as trash just “sinking.”



<h2 class="wp-block-heading" id="h-plastic-in-the-deep-sea">Plastic in the deep sea</h2>



Plastic debris has entered every corner of the ocean, but previously, most of the research has concentrated on floating plastic or beach trash. That changed with this latest study, which took a closer look at what is occurring on the ocean floor. 



Scientists discovered that the Levant Basin - a deep section of the eastern <a href="https://www.earth.com/image/two-continents-meet-along-the-mediterranean-coastline/">Mediterranean</a> off the coasts of Israel, Egypt, and Turkey - is among the world's most contaminated deep-sea areas.



“We used trawls to survey the seafloor and we mainly found plastic bags and packaging that dominate the debris,” said Xing-Yu Li from the <a href="https://www.haifa.ac.il/?lang=en">University of Haifa</a>, the study’s lead author.



This raised a question: how does something so light - something meant to float - end up nearly a mile underwater?



<h2 class="wp-block-heading" id="h-a-forensic-approach-to-trash">A forensic approach to trash</h2>



To answer that, the team decided to treat each plastic item like a crime scene. Every piece of debris was carefully examined using a method called multi-marker analysis. 



This approach looks at everything about the plastic - size, shape, color, material, surface features, and even what kinds of things are stuck to it, like tar or <a href="https://www.earth.com/news/marine-organisms-may-adapt-to-climate-change-but-with-hidden-costs/">marine organisms</a>.



“In the multi-marker approach anything that is found on a piece of plastic is an evidence,” said Xing-yu. “We extracted as many evidence as possible from every piece of waste, more than many previous studies, to build a fuller, more detailed view of the bottom waste.”



Instead of just counting how much trash was found, this method helped researchers understand how it got there, why it sank, and where it might have come from.



<h2 class="wp-block-heading" id="h-why-some-plastic-doesn-t-sink">Why some plastic doesn’t sink</h2>



Most of the plastics found were <a href="https://www.earth.com/news/everyday-kitchen-tool-that-could-be-leaching-toxins-into-your-food-polypropylene-cutting-board/">polyethylene</a> - the same material used in grocery bags. Normally, this kind of plastic floats. But when additives like calcium carbonate (CaCO₃) are mixed in during manufacturing, the plastic becomes heavier. 



Those with CaCO₃ sank closer to the shore. Others, without these additives, drifted farther out before eventually settling on the seafloor.



The study also revealed that the deep basin at over 3,000 feet deep acts like a trap. Pressure and fine sediments help keep the plastic down. 



<a href="https://www.earth.com/news/biofilms-could-change-the-way-we-track-plastic-pollution/">Biofilms</a>, which are slimy layers formed by microbes, usually help weigh plastics down too, but they don’t grow well in this part of the sea. Instead, things like tar, sand, and tiny shells helped plastics stay put.



The scientists noted that these plastic films - while thin and lightweight - are ending up where they can do the most long-term damage. 



Even more troubling, the team found that some of this plastic could become buoyant again if disturbed, but because of how the deep sea works, that rarely happens. Once the plastic settles, it stays.



<h2 class="wp-block-heading" id="h-where-the-trash-is-coming-from">Where the trash is coming from</h2>



The plastic pollution isn’t only from local beaches. According to the research, land-based sources from Egypt, Israel, and Turkey are a big part of the problem. 



Shipping also plays a role, especially in deeper waters. Surprisingly, fishing was not a major contributor - possibly due to strict Israeli regulations.



For years, scientists noticed high levels of plastic at the seafloor, but they didn’t fully understand why. 



“For years in our monitoring reports we have reported a high concentration of plastic debris in this area. It was an unsolved mystery as we know that <a href="https://www.earth.com/news/ocean-floor-harbors-up-to-11-million-tons-of-plastic-debris/">plastic debris</a> should remain floating on the sea surface. Now we have a deep understanding of how it happens,” said Dr. Yael Segal from Israel Oceanographic and Limnological Research (IOLR). 



“The Eastern Mediterranean is the most polluted area in the world, and we must take action for the sake of the next generation.”



<h2 class="wp-block-heading" id="h-long-term-risks-to-marine-life">Long-term risks to marine life</h2>



<a href="https://www.earth.com/news/grapevines-could-offer-a-breakthrough-alternative-to-plastic-packaging/">Plastic packaging</a> is cheap, easy to produce, and used globally - but it doesn’t go away. It breaks into smaller pieces and can remain in the environment for hundreds of years. 



Deep-sea habitats are already fragile, and adding plastic into the mix could disrupt food webs, introduce toxins, and harm species that haven’t even been fully studied yet.



“As the head of the national monitoring program, I see firsthand how plastic pollution is impacting the entire sea environment: beaches, water, sea bottom, and even local turtle populations,” said Dr. Segal.



Professor Revital Bookman said that the discovery is fascinating in the worst possible way. 



"The eastern Mediterranean is quietly turning into a deep-sea landfill. Plastics that we use for only a few minutes are ending up trapped for centuries, threatening deep marine ecosystems we barely understand," noted Professor Bookman. 



<h2 class="wp-block-heading" id="h-what-needs-to-happen-next">What needs to happen next</h2>



According to the researchers, this study changes how we should think about ocean pollution. Plastic doesn’t just float around until it hits a beach. It travels far, interacts with other pollutants like tar, and ends up in hidden places. 



“This previously overlooked dynamic necessitates a broader perspective on pollution processes in marine environments,” said Professor Bookman. 



“Without systematic deep-sea accounting, we risk underestimating the true environmental footprint of plastic pollution and misallocating mitigation efforts by neglecting offshore and deep-sea sinks.”



To deal with this, the experts call for coordinated efforts across the region. Countries that share the sea need to work together on monitoring, cleanup, and prevention. 



Without a shared strategy, plastics will continue piling up, silently choking one of the planet’s most mysterious ecosystems.



The full study was published in the journal <a href="https://www.sciencedirect.com/science/article/abs/pii/S0025326X25009671?via%3Dihub" target="_blank" rel="noreferrer noopener">Marine Pollution Bulletin</a>.

U.S. Secretary of State John Kerry is visiting Antarctica to hear reports on global warming from the scientists there – making him the highest-ranking U.S. official to visit the frozen continent.

Kerry is visiting <a href="https://www.usap.gov/videoclipsandmaps/mcmwebcam.cfm" target="_blank" rel="noopener">McMurdo Station</a>, one of the American research bases on the southern continent, as well as the South Pole. Kerry’s goal, according to spokesman John Kirby, is to talk to researchers on the continent about recent findings on climate change before joining international climate talks in Morocco.

McMurdo is the base for several scientific programs studying glacial geology, ocean and atmospheric sciences, ecosystems and more. It is also the headquarters of the Antarctic Writers and Artists program.

The trip is in character for John Kerry, who has made increasing awareness and indoctrination about climate change a focus of his diplomatic work. 

The West Antarctic Peninsula, where McMurdo Station is located, is one of the global areas most affected by climate change. According to <a href="http://earthobservatory.nasa.gov/IOTD/view.php?id=83672" target="_blank" rel="noopener">NASA’s Earth Observatory</a>, the damage to the West Antarctic Ice Sheet already may be irreversible. 

New climate models show from NASA the ice sheet, which has existed since the last ice age, <a href="http://www.nytimes.com/2016/03/31/science/global-warming-antarctica-ice-sheet-sea-level-rise.html" target="_blank" rel="noopener">could disintegrate within decades</a>, raising sea levels by as much as 12 feet.

Kerry flew to the southern continent from New Zealand on Friday, after being delayed a day by bad weather. After landing at the U.S. hub of operations, Pegasus Ice Runway at McMurdo Station, he and his entourage transferred to another plane to travel to the South Pole research station. He planned to return to McMurdo for the night.

During Secretary Kerry’s travels, he took time to contact President-elect Donald Trump and offer his congratulations.

After his trip to Antarctica, Kerry plans to return to New Zealand on Saturday to meet with Prime Minister John Key. He will then travel to the Middle East for meetings, continuing on to Morocco for the <a href="http://unfccc.int/meetings/marrakech_nov_2016/meeting/9567.php" target="_blank" rel="noopener">United Nations Framework Convention on Climate Change</a> talks.

Kerry’s Antarctic trip has made him the first U.S. Secretary of State to visit all seven continents during service.

Donald Trump presidency spells concern for environmentalists – the months before Election Day included pledges to increase oil drilling, fracking and use of coal, as well as “canceling” the Paris Agreement to reduce greenhouse gas emissions.

These promises – and Trump’s stated belief that global warming is a “hoax” – point to trouble for some of the environmental policy passed during President Obama’s administration. 

It’s likely the Trump administration will work to limit or even do away with the <a href="https://www.epa.gov/cleanpowerplan/clean-power-plan-existing-power-plants" target="_blank" rel="noopener">Clean Power Plan</a>, environmentalists and policy experts predict. The plan sets a national limit on carbon emissions from power plants, in an effort to reduce human contributions to climate change.

However, the plan is currently being challenged in court, and even if it survives, the Trump administration could seek to remove it.

The <a href="https://www.nrdc.org/" target="_blank" rel="noopener">Natural Resources Defense Council</a> has pledged to continue supporting the plan, pointing out that in at least two of the states Trump won, Maine and Florida, the majority of voters believe global warming is a major concern. 

Trump’s pledges to save the coal industry may be counteracted by a decline in demand and lack of interested investors. Most investors are looking at solar or wind power instead, due to lower cost and higher interest from consumers, according to the <a href="http://www.sierraclub.org/" target="_blank" rel="noopener">Sierra Club</a>. 

Trump has also promised to increased hydraulic fracturing, known as fracking, as well as to open public lands and offshore areas to oil drilling.

A Trump presidency spells risks for protections placed by Obama on Alaska and the Atlantic Coast too, allowing for drilling in those locations, though the president-elect has not made any direct statements on whether or not he would do so.

Along the Atlantic seaboard, the fishing and tourism industries have spoken out against allowing drilling. These industries are already gathering resources to fight any attempts to open their coastal waters.

Fracking has been in the news recently after two major earthquakes connected to the practice <a href="http://www.earth.com/news/cushing-earthquake-no-pipeline-damage/" target="_blank" rel="noopener">hit Oklahoma</a> in recent months. The quakes have led to the shutdown of dozens of wastewater injection wells, where the toxic water produced by the fracking process are injected deep into the Earth. <a href="https://earthquake.usgs.gov/research/induced/" target="_blank" rel="noopener">Induced earthquakes</a> can occur when wastewater injection puts pressure on faults, causing them to shift.

Environmentalists are also worried about what a Trump presidency spells for the study of climate change, whose study he has claimed is a hoax. <a href="https://www.nasa.gov/" target="_blank" rel="noopener">NASA</a> has played a major role in the study of global warming, and some Republicans have called to end the agency’s involvement in that study.

New sustainable street lights in Las Vegas are being planned in order to reduce the city’s electric bill and help the environment – and they’re powered by footsteps. 

The new technology involves installing pads in the sidewalk that absorb the kinetic energy created by people walking over them. The energy is stored until nightfall, then used to power the lights overnight.

The street lamps also include solar panels to contribute energy to the system, which stores the power in batteries for light overnight.

Not only do the lamps work with no electricity cost, they also provide WiFi hotspots and cellphone charging stations.

The lights are the creation of <a href="http://www.engoplanet.com/" target="_blank" rel="noopener">EnGoPlanet</a>, a New York-based startup. The company created the lamps after judging wasteful the more than 300 million legacy street lamps around the world costing $40 billion to run and producing 100 million tons of carbon dioxide each year. Carbon dioxide is a <a href="http://climate.nasa.gov/causes/" target="_blank" rel="noopener">greenhouse gas</a> and the main contributor to atmospheric carbon thought to be linked to climate change.

The company also saw that the poles of street lights could be modified so that rather than simply taking up space and holding the lighting element up, they could provide access to electricity and the internet at no additional cost.

The city of Las Vegas is the first to adopt the new technology but will be joined by St. Louis, Missouri, Philadelphia, Pennsylvania, and the country of Oman. 

EnGoPlanet has also kicked off an <a href="https://www.indiegogo.com/projects/let-s-lightup-africa-power-of-footsteps-the-sun-solar-technology#/" target="_blank" rel="noopener">Indiegogo campaign</a> to install the street lamps in 10 African villages that have no access to electricity, free of charge. The ability to charge mobile phones will make it much cheaper and easier for residents of the village to keep in contact with their friends and family, according to EnGoPlanet.

EnGoPlanet also provides other clean-energy products such as a solar benches that include lighting, WiFi hotspots, and charging stations.

Californians upheld their two-year-old plastic bag ban on Tuesday, encouraging environmentalists in their fight against pollution in the state. 

<a href="http://www.cawrecycles.org/landing" target="_blank" rel="noopener">Californians Against Waste</a>, the group that led the campaign in the state legislature to ban plastic shopping bags two years ago, called it a “significant environmental victory.” The group estimates 25 million single-use plastic bags are thrown away in California every day, adding to the state’s pollution.

The group gathered environmental groups, grocers, and others to form a coalition to uphold the ban at the ballot box, encouraging voters to approve Proposition 67.

The <a href="http://plasticsindustry.org/apba/" target="_blank" rel="noopener">American Progressive Bag Alliance</a> (APBA), which represents the plastics industry and pushed to have the initiative on the ballot in the hopes that the ban would be repealed, claimed the plastic bag ban would not reduce waste in a meaningful way, but instead threaten American manufacturing jobs.

Media Matters <a href="http://mediamatters.org/research/2014/10/08/californias-plastic-bag-ban-myths-and-facts/201064" target="_blank" rel="noopener">disputes those claims</a>, stating that plastic bag bans significantly reduce both environmental waste and energy use. They also found that banning plastic bags reduces bag litter significantly, citing the results of bans in San Jose, California and the Republic of Ireland. 

Plastic bag litter is the sixth largest source of pollution on coasts, according to data collected during the <a href="http://www.oceanconservancy.org/" target="_blank" rel="noopener">Ocean Conservancy</a>’s International Coastal Cleanup each year. Plastic bags can trap sea creatures and be mistaken for jellyfish by others, such as <a href="http://onemoregeneration.org/2011/03/13/killer-plastic-bags-choke-rare-leatherback-sea-turtle/" target="_blank" rel="noopener">sea turtles</a>, which try to eat the bags and can choke and die.

Paper bags and reusable bags will still be available for a fee though Californians rejected Proposition 65, which would have put fees collected by grocers into environmental programs.

The APBA claimed this would put the fees into grocers’ pockets; however, grocers already <a href="http://www.latimes.com/opinion/editorials/la-ed-plastic-bag-propositions-20160908-snap-story.html" target="_blank" rel="noopener">pay out of pocket</a> to purchase grocery bags, which they previously gave shoppers for free.

Dead fish in Oregon rivers are a great source for wildlife biologists’ newest tool to monitor bear populations: bear spit.

According to <a href="http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0165259" target="_blank" rel="noopener">a new study</a> published in the journal <a href="http://journals.plos.org/plosone/" target="_blank" rel="noopener">PLOS ONE</a>, using saliva samples found on half-eaten fish is an even better way to monitor the bears than the feces and hair upon which the biologists previously relied.

Non-invasive DNA testing is a tool frequently used by wildlife biologists, often in the form of testing hairs snared on trees, bushes and other features, or testing of discovered scat (fecal matter). This so-called environmental DNA, or eDNA, can be expensive (in the case of hair) or not particularly effective (scat).

But when salmon populations are up, the bears that hunt them don’t generally eat the whole fish, said Dr. Rachel Wheat, the study’s lead author, who recently received her doctorate from the <a href="https://www.ucsc.edu/" target="_blank" rel="noopener">University of California, Santa Cruz</a>. They often prefer to eat the brains and throw away the rest, she said.

Wheat and other scientists wondered if they could collect DNA from bear spit left in the braincases of the fish carcasses. Turns out they could, and the method is a more effective, easier and less expensive tool for monitoring brown bear DNA.

eDNA sampling allows researchers to distinguish between individual brown bears, offering valuable estimates of how many bears are hunting in a particular area, allowing them to track the population and spot any major changes.

The scientists hope this method of tracking wildlife populations can spread to other bears and even other animal species, suggesting wildlife biologists consider using saliva on food remains or bait as a cheap, effective way to monitor animal populations.

Tracking animal populations is vital when it comes to spotting any potential illnesses, problems in their habitats, or other conservation threats.

An electricity coalition of power giants is working towards lowering carbon emissions. 

Agents from nine countries are reaching out to international organizations and development finance institutions to work towards lower carbon emissions to zero. 

The <a href="http://www.globalelectricity.org/en/" target="_blank" rel="noopener">Global Sustainable Electricity Partnership</a> (GSEP) offered to help development finance firms identify which new technology investments can help developing countries reach the emissions standards put forth in the Paris Agreement on schedule.

The GSEP’s member firms have been promoting low-emission technology similar to the standards adopted by the Paris Agreement and spending time implementing new technology in their own countries, according to the <a href="http://www.globalelectricity.org/en/index.jsp?p=298" target="_blank" rel="noopener">open letter</a>.

The 10 member countries of the GSEP provide about a third of the world’s electricity; 60 percent of that is without any direct carbon emissions, the letter said.

The electricity coalition also offered a number of recommendations for a “low-carbon future”: establishing clear long-term policies to address energy issues and related legal, regulatory, economic and environmental matters; approaching energy production systematically, including supply chains and aftereffects; creating public-private energy partnerships; and investing in new and innovative research and development of low-carbon and no-carbon technology. 

These recommendations are increasingly important as more than 2 billion people seek new or reliable access to electricity, the GSEP opined.

Because coal is relatively low-priced and abundant, many poor or developing countries <a href="http://www.ibtimes.co.uk/coal-renaissance-poor-developing-countries-hampering-emissions-targets-1509572" target="_blank" rel="noopener">turn to coal to generate electricity</a>. Coal produces more carbon emissions than any other fossil fuel, and its use contributes to air pollution and global warming. However, many developing nations don’t have access to low-emission energy sources or the financial means to develop them. 

The Global Sustainable Electricity Partnership, which formed in 1992, seeks to join forces with development finance institutions and other organizations working to achieve the goals of the Paris Agreement. The partnership has helped to develop low-emission energy projects in several developing countries in the past two decades. 

The letter encourages any interested companies to contact the GSEP.

Cosmetic microbeads are more harmful to the environment than many had thought.

Microbeads, once a hot new ingredient in cosmetics, may soon be banned from use in consumer products. A recent study by a team of scientists led by Professor Alison Anderson at <a href="https://www.plymouth.ac.uk/" target="_blank" rel="noopener">University of Plymouth</a> focused on public opinion on microbeads, the teensy plastic balls in many face washes and cosmetics. 

The team has estimated that between 4,600 and 94,500 microbeads could be released from an exfoliating wash in a single use. Once discarded, the beads are highly likely to drain into waste water, pass through sewage treatment, and then flow right into aquatic ecosystems. 

The study, published in Marine Pollution Bulletin, found that certain people were aware of the hazard but that there was widespread surprise about the high number of cosmetic microbeads released into the environment per use, calling it “unnecessary,” “unnatural,” and “fake.”

"Participants in the study reacted with shock and disbelief when they were shown the quantity of microbeads in the sample products,” said Anderson. “If microbead content was labelled more clearly we would expect to see a positive response from consumers and also broad support for a ban.”

This past August, the UK House of Commons Environmental Audit Committee published a report asking the government to ban microbeads due to their potential to damage the environment.

The study revealed that while self-identified environmentalists were generally aware of the issue, average students were not. Both groups, however, were surprised by the number of microbeads and the scale of the potential environmental impact. The results suggest that the public could get behind a proposed ban, given increased education and awareness surrounding the issue.

According to Professor Richard Thompson, head of the University’s International Marine Research Unit, "Microbeads might be a small percentage in the overall picture, but recent reports regarding their use have represented a positive step towards resolving the much wider problem of marine debris. They are an avoidable source of microplastic to the environment and legislation would be a welcome step. This study demonstrates there would be public support for such a measure, and that future policies should be developed in close consultation with natural and social scientists to ensure they achieve the desired result."

The dinosaur fossil of a "mud dragon" discovered at a construction site in southern China is offering new clues about bird-like dinosaurs: they were evolving just before an asteroid struck the Earth 66 million years ago, causing a mass extinction.

The dinosaur fossil is of a previously unknown species of oviraptorosaur, a type of feathered dinosaur with two legs, wings and a beak. Scientists have named it Tongtianlong limosus: “muddy dragon on the road to heaven” or “mud dragon” for short.

The <a href="http://www.nature.com/articles/srep35780" target="_blank" rel="noopener">discovery of T. limosus</a>, along with several other discoveries of new species of oviraptorosaurs in recent decades, shows that the feathered dinosaurs were rapidly evolving into new and separate species just before the asteroid wiped out most life on Earth. 

The oviraptors could have been among the last dinosaurs to have a growing, diversifying population before the mass extinction of the giant reptiles, said researchers from the <a href="http://www.ed.ac.uk/">University of Edinburgh</a>, <a href="http://en.cags.ac.cn/" target="_blank" rel="noopener">Chinese Academy of Geological Sciences</a> and Dongyang Museum, who conducted the study. The mud dragon is one of six new oviraptor species found in the Ganzhou area in recent years.

The findings are giving scientists some insight into how oviraptors and other dinosaurs lived ahead of the extinction event: the reptiles appear to have been flourishing in the region, the researchers said. The discovery of new oviraptor species in Asia and North America also add to scientists’ understanding of the family of dinosaurs that show some similarities to modern birds.

The researchers estimate that the mud dragon lived between 66 and 72 million years ago. The fossil is remarkably well preserved; the oviraptor was preserved lying on its stomach, wings and neck stretched out and head raised. Scientists believe this may have been the position the dinosaur died in.

By comparing the skull of T. limosus to other oviraptors that once lived in the area, scientists believe the evolution of so many different oviraptorosaur species may have resulted from environmental changes and varying diets.

EU ice age could be imminent – is a “Little Ice Age” destined for Europe?

From the mid-1300’s until the mid-1800’s, Europe experienced what is known to as the “Little Ice Age.” While not a “true” ice age, temperatures dipped much lower than usual: the Thames River even froze over many times. 

It is thought the Little Ice Age was in large part caused by decreased levels of solar radiation. Today, the sun is in its “quietest” period in over a century and has some scientists worried that Europe could be headed toward another “mini EU ice age.”

In June 2016, experts noticed the sun had entered what is referred to as “cue ball mode,” where no sunspots can be seen. While solar activity is usually cyclical, if the cue ball mode trend were to continue, it could greatly impact weather patterns.

After another period of low activity occurred in February, Vencore Weather predicted “the next solar minimum is approaching.” During a solar minimum, solar flare sightings a few and far between, and brutally cold winters ensue.

The longest recorded solar minimum lasted 70 years, from 1645 until 1715, which arguably saw the most bitter winters of the Little Ice Age.

Iran’s Lake Urmia was once the second-largest hypersaline lake in the world after Brazil’s Araruama Lake. Not anymore.

Lake Urmia’s volume has declined by more than 80 percent in recent decades – a team of scientists led by doctoral student Somayeh Shadkam believes they have tracked down the two major causes: climate change and agricultural use of the water that once flowed to the lake.

<a href="http://pure.iiasa.ac.at/13926/" target="_blank" rel="noopener">The study</a> found saving Lake Urmia requires Iran to improve its water management practices and international cooperation on climate change, said Shadkam, of the <a href="http://www.iiasa.ac.at/" target="_blank" rel="noopener">International Institute for Applied Systems Analysis</a> and <a href="http://www.wur.nl/en.htm" target="_blank" rel="noopener">Wageningen University</a>.

The study looked at 50 years of water data – from 1960 until 2010 – from the lake. Additionally, Shadkam and her colleagues have conducted past studies on how climate change has affected and will continue to affect the lake. Those studies used hypothetical climate change models to predict future water flows into the lake. The new study focuses on the past and present instead of the future, to show how much the lake has declined and why.

The new study found that annual water flow into the lake dropped by about 48 percent over the 50 years of the study. Around 60 percent of that decline was due to climate change and drought conditions; the remaining 40 percent was due to human use, mainly diverting freshwater for irrigation before it reaches Lake Urmia. 

The study published in <a href="http://iaglr.org/journal/" target="_blank" rel="noopener">The Journal of Great Lakes Research</a> suggested that reducing human water usage would not be enough to save the lake – climate change would need to be addressed as well.

Lake Urmia’s decline has launched it into the news recently. In August, <a href="http://news.nationalgeographic.com/2016/08/why-giant-green-lake-turned-blood-red-iran-algae/" target="_blank" rel="noopener">National Geographic</a> reported the lake had turned from its usual green to blood red. The cause was likely algae and bacteria that grow well in hypersaline conditions. As Lake Urmia shrinks, its water becomes saltier, providing perfect conditions for an algae and bacteria bloom, scientists told the magazine.

The lake also became the focal point for a social media campaign against climate change. Iranians using the hashtag <a href="https://twitter.com/hashtag/iamlakeurmia" target="_blank" rel="noopener">#IamLakeUrmia</a> have pushed for <a href="http://www.un.org/en/index.html" target="_blank" rel="noopener">United Nations</a> action to save the lake, even presenting <a href="http://www.tehrantimes.com/news/407890/I-m-Lake-Urmia-petition-signed-by-1-7m-Iranians-presented-to" target="_blank" rel="noopener">a petition with 1.7 million signatures</a> to the organization.

The Brazilian free-tailed bat is the fastest flyer of all aviators. 

There is a brand-new world-record holder for fastest speed of horizontal flight in the animal kingdom: the noble title previously had been held by the common swift, which flies up to 100 kilometers per hour. But scientists at the Max Planck Institute for Ornithology in Radolfzell have learned that the Brazilian free-tailed bat can fly up to 160 kilometers per hour, due in large part to an especially aerodynamic body shape and long wings.

Honorable mention goes to peregrine falcon, reaching up to 300 kph while diving. Comparatively, modern aircrafts have to reach 300 kilometers per hour in order to take off.

Bats are typically considered to be slower flyers because of their less efficient wing structure; animals with wider wings generate greater wind resistance than those with long, narrow wings. Against all odds, the Brazilian free-tailed bat still finished first.

Kamran Safi from the Max Planck Institute for Ornithology noted, “Initially, we could hardly believe our data, but they were correct: at times, the female bats, which weigh between 11 and 12 grams, flew at speeds of over 160 kilometres per hour – a new record for horizontal flight.”

The speeds were recorded through a radio transmitter attached to the back of the bat that falls off after two days. Added Dina Dechman of the Planck Institute, "It was not easy for the pilot to follow the fast-flying animals so that we could localize them accurately and measure their flight path continuously.”

Female chimpanzees hire babysitters, study finds.

It turns out humans aren’t the only species who use babysitters. Chimpanzees, humankind’s closest living relative, have been seen to hire babysitters to wean their offspring faster, allowing mothers to reproduce again sooner.

A study performed by scientists at the University of Toronto led by Iulia Badescu observed 42 pairs of chimpanzee mothers and infants at Ngogo in the Kibale National Park in Uganda. The purpose was to examine the pattern of “alloparenting,” a.k.a. babysitting, where chimpanzees other than the mother helped with child care. Findings were published in a paper in the journal <a href="http://rsos.royalsocietypublishing.org/" target="_blank" rel="noopener">Royal Society Open Science</a>.

"Infants who were held and carried more by babysitters nursed less often and drank less milk," said Badescu. "This means that they were becoming more nutritionally independent compared to infants of the same age who were babysat less or not at all. They were going through the weaning process quicker, and would likely be done weaning at a younger age."

As a result, the mothers were able to continue to reproduce. But not all female chimpanzees seem to believe in babysitters.

According to Badescu, “In other chimpanzee communities, babysitting may be a behaviour that rarely occurs. Our findings emphasize the significance of babysitting as a flexible component of female reproductive strategies in some species.”

Badescu and her team conducted an additional study that found chimpanzee mothers allowed their offspring to nurse for comfort, not just nourishment, even after lactation was over. "The young chimps were already weaned but continued to make contact with their mother's' nipple not for nutrition, but presumably for emotional purposes, when they needed to be comforted," said Badescu. 

This study was published in the American Journal of Physical Anthropology last month.

<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>.

<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>.

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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