<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

Plastic 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.

Rising temperatures that result from global warming may lead to major losses for the European wine industry. New research is shedding light on the potential impact of warmer weather in <a href="https://www.earth.com/image/the-western-mediterranean-sea/">Mediterranean</a> countries. The study reveals that labor and productivity could suffer as agricultural workers try to adjust to the heat.

Unlike most other major industries, the production of wine is still largely operated by manual workers. Because of this, experts believe the wine industry is likely to take a direct hit from the effects of global warming. The researchers set out to examine the influence of heat on the productivity and labor output of manual grape-picking workers in Cyprus to test this theory. These laborers work in temperatures that reach over 96 degrees Fahrenheit. 

The researchers used an innovative technique known as time-motion analysis to evaluate labor output and productivity of seven workers. Time-motion analysis is a reliable method of discovery, as it can account for every second spent by each worker during every shift.

The study established that hot summer temperatures coincided with labor loss up to 27 percent. The workers felt they were exerting more energy due to the impact of the heat on their metabolic and cardiovascular systems and labor output suffered as well. The hotter temperatures caused a need for irregular breaks, and the workers engaged in working activities for 15 percent less time. 

The findings of this study, published in the journal <a href="http://www.tandfonline.com/loi/ktmp20">Temperature</a>, suggest that workplace heat is directly related to labor and productivity losses, particularly in European agricultural workers. The wine industry makes up 0.2% of all the goods and services produced worldwide, which means increased temperatures are a potential source of economic losses on a global scale.

The study is an unprecedented assessment of the impact of workplace heat on European agriculture workers. However, the authors express a need for expansion of this study to accurately predict the scope of global warming’s influence on agricultural laborers in the wine industry. Further research is needed that will include wine production workers in other countries.

Billions of gallons of <a href="https://www.earth.com/news/oklahoma-earthquake-wastewater-injection/">wastewater</a> result from hydraulic fracturing. While this technique has produced a wealth of energy resources for the United States, researchers are taking a look at the environmental impact of this unconventional process. According to a new report, the release of wastewater in Pennsylvania has contaminated a watershed with radioactive material and endocrine-disrupting chemicals.

Hydraulic fracturing, or “fracking,” is a method of extracting gas and oil. According to the U.S. Energy Information Administration, this practice accounted for over half of oil production and two-thirds of gas production in the United States in 2015, and these numbers are expected to grow. Hydraulic fracturing has led to a major shift away from relying on coal, which could significantly reduce greenhouse gas emissions. However, environmental risks also come along with the process such as ground and surface water contamination. 

Fracking produces large amounts of wastewater containing radioactive material, salts, metals, endocrine-disrupting chemicals and polycyclic aromatic hydrocarbons that pose environmental and health risks. A recent report in Pennsylvania estimates that 10,000 oil and gas wells in the Marcellus Shale produced 1.7 billion gallons of wastewater in 2015. The water is collected in facilities to be treated before it is released, but the treatment is limited. 

Bill Burgos led a team of experts from Penn State, Colorado State, and Dartmouth in an effort to determine how effective these water facilities are in treating the wastewater from hydraulic fracturing. They sampled water and sediment from a lake located downstream from two of the treatment facilities. The analysis revealed peak concentrations of radium, alkaline earth metals, salts and organic chemicals present in the same sediment layer.

Two classes of organic chemicals were detected including endocrine-disrupting chemicals known as nonylphenol ethoxylates and carcinogens known as polycyclic aromatic hydrocarbons. The highest concentrations were detected in sediment layers deposited 5 to 10 years ago, which was a peak period of wastewater disposal. High levels of radium were also present in water as far as 12 miles downstream from the treatment plants.

The researchers say that the threats to human health and the environment associated with this contamination are unknown. They express a need for modified regulations of wastewater disposal. The study is published by the <a href="https://www.acs.org/">American Chemical Society</a> in the journal <a href="http://pubs.acs.org/journal/esthag">Environmental Science &amp; Technology</a>.

Seaside sparrows usually live in tidal marshes and build their nests just above normal high tide where they can stay hidden from predators in the vegetation. Rising sea levels may put these birds in a predicament, as unusually high tides will destroy their nests. However, moving their nests up makes them more vulnerable to predators. A new study  from <a href="http://www.americanornithologypubs.org/loi/cond">The Condor: Ornithological Applications</a> reveals that despite the increasing risk of flooding, the nests of these saltmarsh birds face much more of a threat from predation.

Elizabeth Hunter of the <a href="http://www.uga.edu">University of Georgia</a> developed a model to simulate the nesting behavior and success rates of seaside sparrows on the coast of Georgia. Her model revealed that predation poses a much greater threat to the survival of seaside sparrows.  

The study established that flooding risk did not influence predation rates, but predation risk did impact flooding risk - due to the fact the sparrows move their nests lower for safety. Despite this increased risk of flooding paired with a projected spike in sea levels, predation risk remains almost seven times more menacing to seaside sparrows than flooding.

"Nest predation rates are so high right now that even under extreme sea level rise conditions, more nests are likely to be eaten than flooded," explained Hunter. "However, predation and flooding threats act synergistically, meaning that any estimates of the negative effects of sea level rise on the nesting success of Seaside Sparrow or other species are likely underestimates if they do not also consider the negative effects of predation on flooding risk. The flip side of this is that management actions to reduce nest predation could also reduce the risk of nest failures from flooding." 

If conservation strategies are used to protect seaside sparrows from predators, they can overcome the threats of both flooding and predation. The birds could place their nests higher up to stay clear of extreme high tides if their nesting sites were fenced in, for example.

Chris Elphick of the <a href="http://uconn.edu">University of Connecticut</a> is an expert on tidal <a href="https://www.earth.com/news/saltmarsh-sparrow-may-go-exctinct/">marsh birds</a> who commented on Hunter’s study. 

"The study nicely illustrates the importance of understanding the behavior of individual birds when trying to devise strategies to mitigate threats such as predation and tidal flooding,” said Elphick. “Regardless of the threat, it is increasingly clear that tidal marsh birds and their habitats are in trouble, and that we need to explore a range of potential solutions to find ways to help them persist in light of the many ways that humans are changing coastal habitats."

In teaching people about how to reduce their carbon footprints, governments and schools aren’t highlighting the most effective steps, according to a new study.

The four steps that most substantially decrease carbon footprint are eating a plant-based diet, avoiding air travel, living car-free, and having smaller families, the <a href="http://www.lunduniversity.lu.se/">Lund University</a> study said.

However, many governments are still promoting strategies like comprehensive <a href="https://www.earth.com/news/plastic-bottle-threatens-environment/">recycling</a>, which is four times less effective than a plant-based diet, or changing household light bulbs, the study said.

The research analyzed 39 peer-reviewed papers, carbon calculators, and government reports to develop the potential of a range of individual lifestyle choices to reduce greenhouse gas emissions.

The researchers found that government resources from the EU, United States, Canada and Australia don’t highlight these actions, instead focussing on incremental changes with much smaller potential to reduce emissions.

"We recognize these are deeply personal choices,but we can't ignore the climate effect our lifestyle actually has,” study co-author Kimberly Nicholas said. “Personally, I've found it really positive to make many of these changes. It's especially important for young people establishing lifelong patterns to be aware which choices have the biggest impact.”

The authors hope the study “sparks discussion and empowers individuals," she added.

The study is published in the journal <a href="http://iopscience.iop.org/erl">Environmental Research Letters</a>.

Warmer Arctic temperatures have triggered cooler winters and springs in North America, which has weakened vegetation growth and lowered carbon uptake capacity in its ecosystems, according to a new study. 

Researchers analyzed an index of sea surface temperatures from the Bering Sea and found that in years with higher-than-average <a href="https://www.earth.com/news/delay-antarctic-ozone-recovery/">Arctic</a> temperatures, changes in atmospheric circulation affected climate throughout North America. 

In years of intense cold and low precipitation, the team found that the unfavorable conditions adversely affected vegetation growth—including crop yields—which decreased carbon uptake capacity by about 14 percent, the study said.

“If current warming trends continue, it is feasible to conclude that the ecosystems in regions affected by the anomalous climate will suffer greater damages due to the cold and dry spells,” the authors saId.

Further research is needed to obtain a “general conclusion” on the matter, but the research “delivers important implications for climate adaptation,” the authors added.

The study was conducted by Jin-Soo Kim and Jong-Seong Kug at <a href="http://www.postech.ac.kr/">Pohang University of Science and Technology</a> (POSTECH), in collaboration with Su-Jong Jeong from <a href="http://www.sustc.edu.cn/en/">South University of Science and Technology </a>in China.

Home batteries used to store power from solar panels in individual houses could become commercially competitive in the 2030s, a new study found.

The findings from <a href="https://www.imperial.ac.uk/">Imperial College London</a> are based on a new analysis tool that predicts how much consumers will have to pay in the future for energy storage technologies.

"Energy storage has been recognized by leading figures such as Barack Obama and Bill Gates as one of the key technologies of a low-carbon 21st century,” said lead author Oliver Schmidt. “With this analysis tool we can quantify when energy storage becomes competitive and identify where to invest to make it happen, thereby minimizing investor and policy uncertainty."

Renewable energy sources like solar or wind only produce power intermittently and if excess amounts are not stored, they are wasted, the researchers said. Currently, most energy storage technologies are still very new and have a high cost, the study said.

As more units are produced, costs usually fall, researchers said, citing renewable power generators, such as <a href="https://www.earth.com/news/tesla-solar-roof-tiles/">solar panels</a>.

With reasonable investment, energy storage technologies could soon become much cheaper, with electric cars leading the way as battery technology costs fall, the new study says.

The Hinkley Point C nuclear power plant in Great Britain is projected to cost £19.6bn, and produce 3.2 gigawatt (GW) of power on demand when it is completed in 2025, the study said.

If the same amount of money were invested in large-scale lithium-ion batteries, they would be able to deliver 21-41 GW of power when charged, the analysis said. That is more than ten times the UK's current electricity storage capacity, enabling the use of significantly more wind and solar energy.

"This tool allows us to combat one of the biggest uncertainties in the future energy system, and use real data to answer questions such as how electricity storage could revolutionize the electricity generation sector, or when high-capacity home storage batteries linked to personal solar panels might become cost-effective," said study co-author Iain Staffell.

Most air and water pollution in Europe is from coal-powered plants, with Great Britain among the worst polluters, the European Union said.

Half of the plants responsible for the largest releases of air and water pollution were in Britain, with a total of 14, <a href="https://www.eea.europa.eu/">The European Environment Agency</a> reported. Second was Germany with 7, followed by France and Poland, each with 5.

The report was based on 2015 data, the latest available, from 35,000 industrial plants including power stations, petrochemical refineries and metal processing units from the 28 EU members plus Iceland, Liechtenstein, Norway, Switzerland and Serbia.

The report noted progress by the EU in reaching its climate and energy policy objectives for 2020 and 2030, but said <a href="https://www.earth.com/news/obama-protect-streams-forests-coal-mining/">coal</a> is still the most highly used fuel in large combustion plants despite a tripling in the use of biomass from 2004 to 2015.

Coal is still responsible for the largest releases of carbon dioxide, sulfur dioxide and nitrogen oxides, although some plants have significantly decreased their emissions in recent years, the report said.

Plants with the highest emissions in 2015 were the Belchatow power plant in Poland, the Drax power station in Britain, Jaenschwalde in Germany, and Kozienice in Poland, the agency said.

For the past decade or more, climate change has been one of the most newsworthy and heavily researched topics across the globe. Everyone from scientists to politicians (there’s often a wide gap in-between) seems to have an opinion on the impacts of climate change and where we currently stand in its progression. But how much does the common person know?

An opinion poll of 10,000 European citizens is the first in-depth study to assess public engagement with marine climate change issues across 10 European countries. While most of the European population is relatively well informed on marine climate change, “a surprising number are poorly informed, and even misinformed revealing a major failure at communicating climate change science to the public,” says Carlos Duarte, co-author on the paper and Director of the <a href="https://rsrc.kaust.edu.sa/Pages/Home.aspx">Red Sea Research Center</a> in Saudi Arabia.

For example, 54 percent of people polled think that humans play only a partial role or no role at all in climate change. On the other hand, about 30 percent of European citizens believe that loss of <a href="https://www.earth.com/news/arctic-sea-ice-record/">Arctic sea-ice</a> in the summer and sea temperature increases of more than 2°C – impacts that are not expected to occur until at least the year 2100 – have already occurred. “This is hugely disturbing because if these changes have already occurred in their minds, what incentive do these citizens have to demand action to prevent such changes?” worries Duarte.

The study also showed that the public believes that ocean pollution is responsible for the most severe impact to climate change, but they lack understanding of ocean acidification caused by carbon dioxide emissions. Counter-intuitively, researchers found that nations that are currently coping with problems as a result of climate change – such as the Dutch with sea level rise and the Norwegians with sea-ice loss – are the least concerned by the impacts of climate change.

On another disturbing note, many that participated said that they have very little trust in government institutions and their scientists, and instead mostly trust scientists employed by universities. 

“The study shows that we don’t all engage with issues around climate change impacts on the coast and seas in the same way,” explains lead author Paul Buckley from the Centre for Environment, Fisheries, and Aquaculture Science in the UK. “We need to tailor our message given the differences in how audiences across Europe engage with these issues. Making issues that seem remote from people's everyday lives relevant is certainly a challenge.”

Study: Widespread misinformation on the effects of climate change

For the past decade or more, climate change has been...

<a href="https://www.stanford.edu/">Stanford University</a> researchers have made a breakthrough by capturing water freezing in a way that has never been done before. They commanded the process molecule-by-molecule and developed an unusual, dense form called ice seven, or ice VII, which occurs naturally in outer space.

The findings of this study will give researchers an unprecedented account of how liquids transition into solids, which may lead to the creation of materials with amazing new properties. The discovery of ice VII could also shed new light on mysterious <a href="https://www.earth.com/news/failed-planets-scarred-earth/">other worlds</a>.

Arianna Gleason is a visiting scientist in the Extreme Environments Laboratory of <a href="https://www.stanford.edu/">Stanford</a>'s School of Earth, Energy &amp; Environmental Sciences and lead author of the study.

“These experiments with water are the first of their kind, allowing us to witness a fundamental disorder-to-order transition in one of the most abundant molecules in the universe," said Gleason. 

The transformation of materials into gas, liquid and solid states has been extensively studied, but the phase changes are too fast and miniscule to fully observe. Previous research has struggled with these challenges, and researchers resorted to working backward from stable solids in an attempt to view the molecular steps taken to reach this state.

"There have been a tremendous number of studies on ice because everyone wants to understand its behavior," said senior author Wendy Mao. "What our new study demonstrates, and which hasn't been done before, is the ability to see the ice structure form in real time."

The team used the Linac Coherent Light Source, the world's most powerful X-ray laser, for the study. They focused an intense, green laser beam at a small sample of water. The laser instantly vaporized layers of diamond on one side of the target with a force so powerful that it compressed the water to pressures exceeding 50,000 times that of Earth's atmosphere at sea level.

During this water compaction process, the team used a beam from an instrument called the X-ray Free Electron Laser to capture a series of images in only a femtosecond, or a quadrillionth of a second. The images revealed the progression of molecular changes while the pressurized water crystallized into ice VII. The phase change happened in a matter of nanoseconds. The water molecules bonded into rod shapes, which was a surprise to the scientists who expected the molecules would bond into sphere shapes.

The combination of high pressure and snapshot images used for this study could help researchers examine the various ways in which water water freezes depending on pressure and temperature. Due to the conditions of the Earth’s surface, water crystallizes in only one way on this planet known as ice Ih or hexagonal ice. The ice found outside of Earth such as ice VII will give scientists an opportunity to model remote environments.

"Any icy satellite or planetary interior is intimately connected to the object's surface," said Gleason. "Learning about these icy interiors will help us understand how the worlds in our solar system formed and how at least one of them, so far as we know, came to have all the necessary characteristics for life."

The study was published today in Physical Review Letters.

An average of two vertebrate species go extinct every year but few people notice, according to a new study.

Extinctions often attract little attention because the rate seems relatively low and doesn’t pose an immediate threat to natural systems, according to the <a href="https://www.stanford.edu/">Stanford University</a> study. 

"This is the case of a biological annihilation occurring globally, even if the species these populations belong to are still present somewhere on Earth," said co-author Rodolfo Dirzo. 

A 2015 study co-authored by Paul Ehrlich, Stanford Professor Emeritus of Biology, showed that Earth has entered an era of <a href="https://www.earth.com/news/fossil-footprints-recovery-extinction/">mass extinction</a> unparalleled since the dinosaurs died out 66 million years ago. 

In the new study, researchers mapped the ranges of 27,600 species of birds, amphibians, mammals and reptiles - representing nearly half of known terrestrial vertebrate species - and analyzed losses in 177 well-studied mammal species between 1990 and 2015.

More than 30 percent of vertebrate species are declining in population size and range, the study found. All of the 177 mammals for which the researchers had detailed data have lost 30 percent or more of their geographic ranges, and more than 40 percent have lost more than 80 percent, the study said.

Tropical regions have been the hardest hit, particularly the mammals of south and southeast Asia, where all the large-bodied species of mammals analyzed have lost more than 80 percent of their geographic ranges.

As many as 50 percent of the number of animals on Earth have disappeared, as have billions of animal populations. This amounts to "a massive erosion of the greatest biological diversity in the history of Earth," the authors write.

"The massive loss of populations and species reflects our lack of empathy to all the wild species that have been our companions since our origins," said the new study's lead author, Gerardo Ceballos of the<a href="https://en.wikipedia.org/wiki/National_Autonomous_University_of_Mexico"> National Autonomous University of Mexico</a>. "It is a prelude to the disappearance of many more species and the decline of natural systems that make civilization possible."

The researchers call for curbs on human overpopulation and overconsumption - and challenge society to move away from "the fiction that perpetual growth can occur on a finite planet."

The study was published in the journal <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Population declines underway, two species go extinct each year

An average of two vertebrate species go extinct every year...

Rangeomorphs – ancient animals ranging from centimeters to two meters in height – were much larger than the microscopic species that roamed Earth at the same time.

But what made the ocean-dwelling organisms so comparatively huge? 

"What we wanted to know is why these large organisms appeared at this particular point in Earth's history," said Dr. Jennifer Hoyal Cuthill of <a href="http://www.cam.ac.uk/">Cambridge University</a>. "They show up in the fossil record with a bang, at very large size. We wondered, was this simply a coincidence or a direct result of changes in ocean chemistry?"

Rangeomorphs lived in Earth’s oceans between 635 and 541 million years ago. Their bodies branched into fractals, shapes that are still seen in modern organisms.

In some ways, the ancient animals resembled plants more than modern animal life.

Using micro-CT technology, the researchers looked at rangeomorph fossils from Canada, Australia, the UK and Newfoundland. What they discovered may be the earliest evidence of nutrient-dependent growth among ancient animals. This “shape-shifting” ability allowed rangeomorphs to grow larger depending on whether they were in water with more nutrients or oxygen.

The adaptation may have been a response to changes in the ocean’s chemistry during the Ediacaran Period, when rangeomorphs lived.

"During the Ediacaran, there seem to have been major changes in the Earth's oceans, which may have triggered growth, so that life on Earth suddenly starts getting much bigger," Hoyal Cuthill said in a press release. "It's probably too early to conclude exactly which geochemical changes in the Ediacaran oceans were responsible for the shift to large body sizes, but there are strong contenders, especially increased oxygen, which animals need for respiration."

The largest factor may have been a massive influx of oxygen into Earth’s oceans during the Ediacaran. Low oxygen levels prior to that time period may have keep ancient animals small. The study is finding clues that may explain how other animal species became so large.

When conditions changed again in the “Cambrian Explosion,” more large species developed and rangeomorphs were crowded out, the researchers said.

The study will be published in <a href="https://www.nature.com/articles/s41559-017-0222-7">Nature Ecology &amp; Evolution</a>.

How and why did ancient animals grow so large?

One of the most invasive marine species in Europe has arrived on Egypt’s Mediterranean coastline in alarming numbers. According to the <a href="https://www.ap.org/en-us/">Associated Press</a>, the appearance of large swarms of nomad jellyfish is reviving a dispute over the Suez Canal.

The nomad <a href="https://www.earth.com/video/pee-jellyfish-sting/">jellyfish</a>, Rhopilema nomadica, is native to the Indian Ocean and the Red Sea, yet has been showing up in the Mediterranean by way of the Suez Canal since the 1970’s. Despite this fact, many blame the recent invasion on the 2015 expansion of the Suez Canal.

The jellyfish interrupted the Eid al-Fitr holiday last month, as beach-goers avoided the water and took to social media with pictures of the unwelcome visitors. The numbers of nomad jellyfish appearing in the Mediterranean has steadily increased over the years, but this year they are especially dominant.

The Suez Canal has been expanded several times since it was built in 1869. However, the 2015 project was a multi-billion dollar transformation. Egyptian officials deny the expansion is to blame for this year’s unprecedented jellyfish invasion.

Mostafa Fouda, an advisor to the Environment Minister, points out that this is not the first time nomad jellyfish have appeared on Egypt's north coast. “This time the number was just larger than previous years,” explains Fouda.

Egypt’s environmental ministry has set up a team to assess the phenomenon. They believe there are many other factors to be considered for the abundance of alien jellyfish this year such as global warming, the availability of more food, or a lack of predators.

While experts agree that these environmental influences may have allowed a spike in the nomadic jellyfish population, many feel the larger waterway has increased the progression of the creatures from the Red Sea to the Mediterranean.

Jason Hall-Spencer is a marine biologist at Britain's Plymouth University. He says,"The primary cause of the invasion of jellyfish is the Suez Canal. Other ecosystem stressors have allowed them to thrive and become a plague.”

<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-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.

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."
