Climate change reshapes where people live, altering both the desire and the ability to move. When heat waves, droughts, and floods strike, not everyone responds the same way. A study in&nbsp;Nature Communications&nbsp;shows that age and education strongly influence who migrates and who remains.



The research reveals a complex story: extreme weather pushes some groups to leave while trapping others in place. This challenges the image of mass waves of <a href="https://www.earth.com/news/climate-wins-in-2025-came-from-unexpected-places/">climate</a> refugees often evoked in debates.



Study lead author Hélène Benveniste is an assistant professor of environmental social sciences at the <a href="https://sustainability.stanford.edu" target="_blank" rel="noreferrer noopener">Stanford Doerr School of Sustainability</a>.



"Weather extremes can both incentivize people to move away and increase the number of people who don't have the ability to migrate," said Professor Benveniste.



"Our research shows that migration in response to weather, just like migration decisions in general, is highly dependent upon demographic characteristics."



<h2 class="wp-block-heading" id="h-climate-and-migration-patterns">Climate and migration patterns</h2>



Earlier research often gave mixed signals on whether women, men, or people with different education levels were more likely to migrate under extreme <a href="https://www.earth.com/news/where-will-climate-change-hit-hardest-global-index-reveals-vulnerability/">weather</a>. 



By analyzing detailed global migration records, Benveniste and colleagues showed that these contradictions arise because responses vary sharply across demographics and local climates.



The team examined more than 125,000 cross-border cases and nearly half a million within-country moves. They categorized migrants by age, education, and sex, and then connected these groups to weather records like temperature and soil moisture. 



This approach revealed that migration is best understood not by how many move, but by who does.



<h2 class="wp-block-heading" id="h-trapped-and-cannot-migrate">Trapped and cannot migrate</h2>



The new model predicted migration up to 12 times better than previous approaches. Yet weather alone explained only a small fraction of migration, since economics, politics, and social ties also weigh heavily.



Still, striking demographic patterns emerged. Children under 15 were less likely to migrate following extreme heat. Older adults with little education, however, were more likely to leave, while highly educated adults showed little change.



"Our results indicate that many among those most likely to suffer from <a href="https://www.earth.com/news/earth-is-just-three-years-away-from-dangerous-carbon-milestone/">climate</a> change impacts will not be able to get out of harm's way," noted the researchers. 



This creates a "double penalty," where people with the fewest resources both struggle to adapt locally and lose migration as an option.



<h2 class="wp-block-heading" id="h-local-climate-and-migration">Local climate and migration</h2>



Climate zones shape how weather influences moves within countries. In tropical regions, hotter days increased migration among educated adults but had little effect on those with less schooling. 



In arid regions, dry spells spurred moves especially among the least educated, while heavy rains or flooding also triggered departures.



The analysis highlights how vulnerability interacts with opportunity. Those reliant on agriculture, often with little education, may feel a strong push to leave during drought, yet lack the means to relocate across borders. Instead, they may move to nearby towns or cities when conditions deteriorate.



<h2 class="wp-block-heading" id="h-who-migrates-and-who-doesn-t">Who migrates and who doesn't </h2>



The study emphasizes that climate change will not necessarily unleash waves of migrants. Instead, it will reshape the composition of those who move. 



Projections suggest that by the end of the century, older adults with little education may migrate across borders at higher rates, while the youngest and least educated will migrate less.



This shift means that population averages mask the real story: dramatic differences between groups cancel each other out. Policies that only consider total migration numbers risk overlooking those most affected.



<h2 class="wp-block-heading" id="h-responses-to-long-term-changes">Responses to long-term changes</h2>



The researchers caution that responses to long-term <a href="https://www.earth.com/news/wealthy-elite-responsible-for-majority-of-global-climate-warming/">climate</a> change may differ from reactions to short-term weather. 



Communities may adapt with new crops or technologies, reducing the need to move. Yet if conditions outpace these adaptations, migration pressures could rise again.



Destination conditions also matter. High heat in receiving countries can discourage movement for some groups, while wetter conditions may attract others, especially educated adults. 



Household factors, such as whether people have children, further influence decisions, with parents often less likely to move.



<h2 class="wp-block-heading" id="h-preparing-for-future-climate-shocks">Preparing for future climate shocks</h2>



Policymakers often prepare for large waves of climate refugees. But the evidence points to a subtler reality: climate change will alter who is able to move, while many vulnerable groups remain trapped.



"We hope that policymakers use these results as a basis to more squarely address the needs of different demographic groups," Benveniste said. "We need to answer the needs not just of the people who move, but also those who are moving less."



The science is clear: climate-driven migration is less about numbers and more about people. Understanding who moves, who stays, and why is key to preparing for a warmer, less predictable world.



The study is published in the journal <a href="https://www.nature.com/articles/s41467-025-62969-3" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Climate shocks: Who migrates and who stays behind?

Climate change reshapes where people live, altering both the desire and the ability to move. When heat waves, droughts, and floods strike, not everyone responds the same way. A study in&nbsp;Nature Communications&nbsp;shows that age and education strongly influence who migrates and who remains. The research reveals a complex story: extreme weather pushes some groups to leave while trapping others in place. This challenges the image of mass waves of climate refugees often evoked in debates.

In the first study of its kind, researchers have measured the mass of all living organisms on Earth. They found that humans only make up about one ten-thousandth of life on the planet in terms of biomass.

The comprehensive analysis was focused on carbon content, which does not account for the water masses of organisms. The results indicate that the total global biomass is around 550 gigatons of carbon (Gt C).

Study lead author Ron Milo is a biologist at the <a href="https://www.weizmann.ac.il/pages/">Weizmann Institute of Science</a> in Israel. He explained that while the estimates are not exact, they give a sense of proportion.

According to the research, plants add up to more than 80 percent of the world's biomass, outweighing humans by 7,500 to one. Nearly 13 percent of the world's biomass is made up by bacteria, while fungi account for about two percent.

The researchers also discovered that wild <a href="https://www.earth.com/news/humans-mammals-shrink-size/">mammals</a> are 10 times less prevalent than humans. Overall, humans have cut the number of wild animals by 85 percent.

Livestock such as cattle and pigs, on the other hand, are much more prevalent. In addition, poultry such as chicken and turkeys are three times as abundant as wild birds.

“When I do a puzzle with my daughters, there is usually an elephant next to a giraffe next to a rhino,” Milo told <a href="https://www.theguardian.com/uk">The Guardian</a>. “But if I was trying to give them a more realistic sense of the world, it would be a cow next to a cow next to a cow and then a chicken.”

Wild animals are not the only group of organisms that have been substantially impacted by humans. The researchers found that human activities have cut the amount of plant biomass in half.

“Even though short in numbers, we have managed to throw a lot of sand in the air and mess up a lot of things,” said Harvard biologist E.O. Wilson.

“I would hope this gives people a perspective on the very dominant role that humanity now plays on Earth,” Milo told The Guardian. “It is definitely striking, our disproportionate place on Earth.”

The study is published in the <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

In the first study of its kind, researchers have measured...

After nearly 3 weeks of unpredictable behavior, Hawaii's <a href="https://www.earth.com/news/new-fissures-kilauea-evacuations/">Kilauea volcano</a> erupted again on Monday evening. Geologists warn that the volcano is entering into a more violent phase, which will generate larger volumes of lava that can travel farther.

Toxic sulfur dioxide gas has reportedly tripled in the last few days. A river of lava that traveled through four miles of forest and farmland is now pouring into the Pacific Ocean. 

When scorching hot lava makes contact with cooler ocean waters, there is a chemical reaction that propels plumes of lava haze, or “laze,” into the sky. The steam cloud is hovering over the coastline filled with hydrochloric acid and fine particles of glass, which could be shifted by wind.

New fears have also emerged as lava advances deeper onto the property of the Puna Geothermal Venture Plant, now moving within just 300 yards of one of the plant's underground wells. If the lava reaches the wells, it could create hydrogen sulfide, a poisonous gas that has the distinctive smell of rotten eggs.

Thomas Travis is an administrator of the <a href="http://dod.hawaii.gov/hiema/">Hawaii Emergency Management Agency</a>. He warns that the scorching lava could breach the steel that has been used to secure the wells.

“That’s why having lava flow across the well causes some uncertainties that have to be dealt with,” Travis told <a href="https://www.usatoday.com/">USA Today</a>. “To our knowledge, no one has faced this before.”

The geothermal power plant, which supplies power to about 25 percent of the Big Island, has been shut down and around 50,000 gallons of flammable gas has been removed from the property.

Uncertainty persists among hundreds of evacuees who have no relief in sight, while further evacuations could be issued at any time if lava invades new regions of highways or if air quality worsens.

“Residents in the affected area should be prepared to leave the area with little notice due to gas or lava inundation,” stated the Civil Defense agency. “Take action necessary to prepare ahead of time.”

The Kilauea volcano is one of the most active volcanoes in the world. According to the U.S. Geological Survey, the volcano has been continuously erupting since 1983, but has not been explosive until now. The last time Kilauea saw a period of explosive activity was 94 years ago this month, in 1924.

Human activity may be causing cancer in the the animal kingdom. From smoking to obesity, to sunburns, and even the chemicals we use in soaps and shampoos, factors that increase the risk of <a href="https://www.earth.com/news/skin-cancer-cases-outdoor-workers/">cancer</a> vary from the most well-known to some of the most surprising.

But while scientists are working to understand the different ways in which humans develop cancers, a new report has examined the cancer risks that human activity is causing in the animal kingdom. 

Researchers from <a href="https://www.asu.edu/">Arizona State University</a> recently published a paper urging the scientific community to start studying cancer in animals to examine how humans are causing cancers in other species. 

The report was published in the journal Nature Ecology &amp; Evolution and underscores the importance of understanding how humans are changing the environment and raising the risk of cancer in animals. 

“We are changing the environment to be more suitable for ourselves, while these changes are having a negative impact on many species on many different levels, including the probability of developing cancer,” said Tuul Sepp, co-author of the paper. 

Tuul worked with Mathieu Giraudeau and identified many different ways that humans negatively impact wild habitats including polluting the oceans, treating crops with pesticides that have been shown to affect insects, and accidentally leaching chemicals and radiation into the environment.

The researchers state that with all we know about cancer in humans, cancer in wild populations has been largely ignored. 

“Cancer has been found in all species where scientists have looked for it and human activities are known to strongly influence cancer rate in humans,” said Giraudeau. “So, this human impact on wild environments might strongly influence the prevalence of cancer in wild populations with additional consequences on ecosystem functioning.” 

The stress of human activities on animal populations needs to be considered when measuring cancer in animals, according to the researchers. 

“The next step is definitely to go into the field and measure cancer rate in wild populations,” said Giraudeau. “We are now trying to develop some biomarkers to be able to study this. I think it would be interesting to measure cancer prevalence in wild animals in human-impacted environments and also in more preserved areas for the same species.”

In what the <a href="https://www.washingtonpost.com/">Washington Post</a> refers to as “a modern-day Noah’s ark,” animals are being moved across Africa to restore local populations that have dramatically declined or disappeared altogether. One particular organization is, quite literally, breathing new life into the country's national parks. 

<a href="https://www.african-parks.org/">African Parks</a> was founded in 2000 in response to the degradation of protected wildlife areas, which the group suggests can be attributed to inadequate management and a lack of funding. The nonprofit organization currently manages 15 national parks and protected areas in nine countries, spanning over 40,000 square miles.

Malawi has one of the highest rates of deforestation in the world, due primarily to the rapid expansion of agriculture and human settlement. As a result, many species have been pushed out of their homes. Other species, such as elephants and lions, have been completely wiped out by poachers in some regions.


In collaboration with the <a href="https://www.facebook.com/Department-of-National-Parks-Wildlife-420351424735202/">Department of National Parks and Wildlife</a> (DNPW), African Parks achieved the largest-ever translocation of elephants by 2017. Over 500 elephants and 1,500 other animals of various species were shipped in planes and trucks from Liwonde National Park and Majete Wildlife Reserve in southern Malawi to the Nkhotakota Wildlife Reserve in northern Malawi.

Peter Fearnhead is the CEO of African Parks, which is based out of Johannesburg. “We can use these thriving populations to seed other areas,” he told the Post, which is precisely what the group has been doing.

“When African Parks assumed management of Majete in 2003, all of the elephants had been hunted out,” noted the organization's website. 

“Today, after restocking the reserve, more than 400 live there and the area is thriving. In 2015, African Parks assumed management of Liwonde, which now has more than 575 elephants (since the 2016 translocation) and has high levels of human-wildlife conflict.” 

“The same year, we also assumed management of Nkhotakota, which once had more than 1,500 elephants but due to poaching fewer than 100 remained.”

Translocation is a type of human-assisted migration that can be applied to protected areas to reduce the risk of species extinction by broadening the range and numbers of endangered wildlife populations.

Transporting hundreds of elephants was not a simple maneuver. According to the Washington Post, the elephants were given a sedative 10,000 times as strong as morphine before being shipped across southern Africa.

The Washington Post also reports that African Parks now has a massive counter-poaching force, with hundreds of miles of fences, thorough camera surveillance networks, satellite collars for some of the animals, and around 1,000 rangers.

African Parks is currently working with the governments of South Africa and Chad to reintroduce black rhinos to Zakouma National Park in southern Chad. The group has also flown 20 black rhinos from South Africa to Rwanda.

“All too often, headlines on rhinos are about their demise as they teeter on the brink of extinction,” said Fearnhead. “However, today we are participating in an historic event and peering into a brighter future for this species which has persisted on this planet for millions of years.”

African Parks uses 100 percent of its donations for the protection of Africa's wildlife, and contributions can be made <a href="https://www.african-parks.org/donate">here</a>.

African Parks transports animals to boost endangered populations

In what the Washington Post refers to as “a modern-day...

Coal- and oil-fired power plants are known to cause environmental issues that affect the areas immediately surrounding the plants, as well as the global climate. Now, new research shows that getting rid of these plants actually improved human health – lowering the rate of preterm births in neighboring communities and boosting fertility. The study on preterm births was published in the <a href="https://academic.oup.com/aje">American Journal of Epidemiology</a>, while the study on fertility was published in <a href="https://ehjournal.biomedcentral.com/">Environmental Health</a>.

Researchers from the <a href="https://www.berkeley.edu/">University of California, Berkeley</a> compared preterm births and fertility before and after eight California power plants closed between 2001 and 2011. Preterm births often result in a baby spending time in the neonatal intensive care unit, and is a major contributor to infant mortality and health problems as the child age. 

The data showed that the percentage of preterm births (defined as babies born before 37 weeks of gestation) dropped from 7 percent while a plant was open to 5.1 percent for the year after it was shut down. Rates for non-Hispanic African-American and Asian women dropped even more significantly, going from 14.4 percent to 11.3 percent. This 20-25 percent decrease in preterm birthrates was larger than expected, but is consistent with other studies that have linked air pollution near power plants to birth problems. 

The study on fertility and proximity to power plants used similar data, and found that fertility (defined as the number of live births per 1,000 women) increased in the vicinity of recently closed <a href="https://www.earth.com/news/coal-mining-aquatic-life/">coal</a> and oil power plants.

“We were excited to do a good news story in environmental health,” says Joan Casey, a UC Berkeley postdoctoral fellow and lead author of the study. “Most people look at air pollution and adverse health outcomes, but this is the flip side: We said, let’s look at what happens when we have this external shock that removes air pollution from a community and see if we can see any improvements in health.”

The authors believe these findings could help policy makers in the United States come up with strategies for decommissioning power plants and replace them with more renewable sources of energy.

“We believe that these papers have important implications for understanding the potential short-term community health benefits of climate and energy policy shifts and provide some very good news on that front,” says Rachel Morello-Frosch, a UC Berkeley professor of environmental science, policy and management and of public health and co-author of the study. “These studies indicate short-term beneficial impacts on preterm birth rates overall and particularly for women of color.”

This study did not specify the effects of individual pollutants, which would include particulate matter, sulfur dioxide, nitrogen oxides, benzene, lead, mercury, and other health hazards. Rather, it looked at the combined effect of all the pollutants expelled by these power plants. Moving forward, they may attempt to assess this relationship in other states and see if similar results can be found, which may ultimately support the goal of retiring these polluting power plants.

A handful of <a href="https://www.earth.com/news/antibiotics-soil-killing-superbugs/">soil</a> contains millions of bacteria and fungi, which are competing for space and food. Most are essential in creating healthy soil, but a few of these organisms cause devastating crop diseases. A new study has revealed how some harmful microbes use chemical warfare in response to threats from pesticides as well as from neighboring organisms.

Nancy Keller is a professor of Medical Microbiology and Immunology at the <a href="https://www.wisc.edu/">University of Wisconsin-Madison</a> who has studied the interactions among soil pathogens for years, investigating the chemical signals that are sent back and forth among them. 

Keller’s team has managed to interpret a signal from the fungal pathogen Fusarium fujikuroi, which responds to an attack by the bacterial wilt species Ralstonia solanacearum by generating a host of antibacterial compounds to defend itself.

“Ralstonia is a lethal wilt pathogen worldwide and attacks over 200 plants,” said Keller. Fusarium species are also a major cause of fungal wilt diseases in crops.

In a previous study, Keller’s students noticed competition between Ralstonia and Fusarium. A closer inspection revealed that Ralstonia caused the nearby fungi to produce chlamydospores, which help the fungus survive stress. The distinctive structures turned a unique shade of rusty red.

In the current study, the team identified the red compound as bikaverin, a chemical that helps prevent infection from bacteria.

The researchers demonstrated that Ralstonia secretes a compound that causes Fusarium to produce chlamydospores. Next, Fusarium produces antimicrobial agents, including the red bikaverin, to protect the chlamydospores from invasion. 

The scientists discovered that inhibiting the ability of Fusarium to produce bikaverin allowed Ralstonia to successfully invade the spores. 

An unrelated fungal species that is also a damaging plant pathogen, known as Botrytis, genetically acquired the ability to produce bikaverin from Fusarium. Botrytis has the same response to an attack by Ralstonia and produces chlamydospores.

The researchers were surprised to find that Ralstonia could induce bikaverin in both of the fungal species regardless of the environment. Fusarium and Botrytis normally produce the red pigment under very different conditions, primarily based on what nutrients are available. 


Keller said that these call-and-response offensive and defensive maneuvers are certainly just a small part of the chemical signals passed between microbes hidden from view.

“How these microbes interact and talk with each other is still in its infancy,” said Keller. “We really don't know how they talk to each other. And that's where we want to go in our lab.”

A greater understanding of the messages among the microbial communities in soil could help scientists find ways to respond to persistent threats to crops.

The research is published in the journal <a href="http://mbio.asm.org/">mBio</a>.

Hundreds of plastic pebbles have been found on beaches across the world, posing a threat to the health of oceans, wildlife, and humans. The plastic beach stones have been spotted in Cornwall, Devon, Pembrokeshire, Orkney, Spain, Portugal, and Hawaii.

The plastic pebbles, known as plastiglomerate, were first discovered in 2006 by oceanographer Charles Moore while he was surveying plastic on a remote beach in Hawaii.

Experts believe that the main source of the pebbles is <a href="https://www.earth.com/news/mariana-trench-plastic-trash/">plastic</a> that is burned in beach bonfires. After the plastic is melted, it gets tossed around on the beach and mixed with sand, debris, shells, and seaweed. The small stones that result look basically like real pebbles.

According to the <a href="http://www.ramepbc.org/about-us/we-do-much-more-than-just-beach-cleans/cornish-plastic-pollution-coalition/">Cornish Plastic Pollution Coalition</a> (CPPC), the plastic pebbles could easily make their way into the food chain if they get broken down.

“The danger is that they will become shingle-size and be ingested into the food chain, so they need to be removed like any plastic would be,” CPCC coordinator Delia Webb told <a href="http://www.bbc.com/news">BBC News</a>.

“But if people are aware of them we should find more. Cornwall gets hit because of currents coming across the Atlantic and if you are a seasoned beachcomber your eyes get attuned to spotting them.”

The researchers explained that one way to recognize the plastic pebbles is that they float.

Plastic pollution is a problem that will never go away, literally. This is because plastic cannot biodegrade, but instead gradually breaks down into smaller toxic particles known as microplastics. 

Plastic is designed for durability, yet 33 percent of all plastic is only used once. According to <a href="http://www.marinesafe.org/">marinesafe.org</a>, a plastic bottle that holds a single drink will take 450 years to break down into microplastic.

Experts believe that the plastic stones could persist in some form for millions of years if they become buried, creating a geological record of the human pollution of our era.

Friends Happiness Enjoying Dinning Eating Concept

The <a href="https://www.earth.com/news/mediterranean-diet-healthier-aging/">Mediterranean diet</a> consists of a high volume of fruits, vegetables, legumes, whole grains, olive oils, fish, and poultry over red meat and processed foods. This diet happens to be very high in antioxidants, which are molecules that disarm oxidized and highly reactive molecules – or free radicals – which are known to cause damage to cells and tissue. Researchers from the <a href="https://med.nyu.edu/">New York University School of Medicine</a> have published a study examining how the antioxidants in this diet can mitigate the health effects of air pollution.

“Previous studies have shown that dietary changes, particularly the addition of antioxidants, can blunt the adverse effects of exposure to high levels of air pollution over short time periods,” says Chris C. Lim, a doctoral student at the NYU School of Medicine. “What we did not know was whether diet can influence the association between long-term air pollution exposure and health effects.”

The study looks at data from the National Institutes of Health (NIH)-American Association of Retired Persons (AARP) Diet and Health study. This study followed over half a million people – average age of 62 – over 17 years. The study subjects were from 6 states; California, Florida, North Carolina, Louisiana, New Jersey, and Pennsylvania – along with two cities (Atlanta and Detroit). Over the course of 17 years, 126,835 members of the study group died.

The research team sectioned the participants into five groups based on their level of adherence to the Mediterranean diet, and estimated their long-term exposure of fine particulate matter (PM2.5), nitrous oxide (NO2), and ozone (O3) based on census tract information.

A comparison between the least and most adherent to the Mediterranean diet found some compelling results. For those least adherent to the diet, deaths from all causes increased by 5 percent for every 10 parts per billion (ppb) increase in long-term average NO2 exposure. For those most adherent, it only increased by 2 percent. Deaths from cardiovascular disease increased by 17 percent for every 10 micrograms per cubic meter increase in long-term average PM2.5 exposure for those least adherent to the diet, compared to 5 percent among those most adherent. For every 10 ppb increase in NO2 exposure in the least adherent, these deaths increased by 10 percent – compared to 2 percent for the most adherent. Additionally, heart attack deaths increased by 12 percent for every single ppb increase in NO2 exposure in those least adherent, whereas for those most adherent, the increase was only 4 percent. 

Interestingly, it does not appear that the Mediterranean diet protected against the harmful effects of long term ozone exposure.

“Given the benefits we found of a diet high in anti-oxidants, our results are consistent with the hypothesis that particle air pollution caused by fossil fuel combustion adversely affects health by inducing oxidative stress and inflammation,” says George Thurston, director of the Program in Exposure Assessment and Human Health Effects at the Department of Environmental Medicine, <a href="https://med.nyu.edu/"> NYU School of Medicine</a> and senior author of the study. “On the other hand, the ozone effect was not significantly blunted by a Mediterranean diet, so ozone apparently affects cardiac health through a different mechanism.”

Because roughly a quarter of the American population lives in an area where air pollution levels are 10 micrograms per cubic meter or more above the lowest exposure, the results of this study show that it would be wise for many Americans to take up the Mediterranean diet.

Mediterranean diet helps battle health effects of air pollution

The Mediterranean diet consists of a high volume of fruits,...

In 1947, the first Qantas Airlines “Kangaroo route” from Perth, Australia to London took four days and nine stops.  This year Qantas started a non-stop service from Perth to London that takes only 17 hours. Take a step back, the Clipper Route is the standard for sailing from London to Australia (and could be carried onward around the globe).  A good speed for sailing from Plymouth, England to Sydney, Australia is 100 days, covering about 13,750 miles in that time. 

How strangely our perception of the size of the Earth changes with technology.  100 days at sea seems a lifetime compared to 17 hours in a climate controlled airplane cabin.  In his book Arctic Dreams, Barry Lopez elaborates on this phenomena:

“To a modern traveler the arctic landscape can seem numbingly monotonous, but this impression is gained largely, I think, from staring at empty maps of the region and from traveling around it by airplane.  The airplane, like the map, creates a false sense of space; it achieves simplicity and compression, however, not with an enforced perspective but by altering the relationship between space and time.”

Lopez examines the controlled environment of the airplane and how the constant radio static, artificial lights, etc. dull the experience of the landscape right outside the window.  Dr. Zoe Thompson, in her book, Urban Constellations: Spaces of Cultural Regeneration in Post-Industrial Britain, elaborates more on the effect of windows in particular in the distortion of the landscape:

“The optimum viewing point is still a question of the correct distance.  New media technologies and material technologies such as glass serve to obliterate distance, to erase it.  But this distortion that glass enables is a distortion of our relationship to ‘first nature’. Thus, the technologized second-nature surface of plexiglass reveals something of the origin of this deformed presentation of the natural world at the same time as it spectacularizes it.”

We don’t even realize very often how something as simple as glass distorts our view of the natural world.  Watching the world through the window of an airplane, a bus, or a car is more like watching the world on a television screen in many ways than the world you see walking around.

I remember reading years ago of a man who was driving across Utah in the summer and broke down.  The man didn’t carry any water with him and he died relatively quickly before anyone stopped to help him.  It’s easy to understand how someone setting out in a journey across the desert in a self-contained, air conditioned vehicle could think himself impervious to the elements.  It’s much harder to imagine someone setting out on foot across Utah in summer and not bringing adequate water. Utah is much larger than it appears from the driver’s seat and I have even been guilty of being underprepared and running out of gas outside a town that I was sure I would make before I needed to fill up.  Luckily for me, a cop drove me to the gas station and I got back on the road relatively quickly.

According to <a href="http://www.californiatrailcenter.org">California Trail Center</a> it took between three and six months to complete the California Trail.  The California Trail covered the same route as the Oregon Trail until Idaho where the two diverged.  Depending on where the pioneers got on the trail, the mileage could vary but the trail was usually around 2000 miles.  A mere distance of 10 to 20 miles a day was covered by the average wagon train, a difference that can be covered on foot a day by a strong back packer.  The difference in time to cross the vast space of land we call North America today in a car is vast. Google Maps boldly asserts that the driving time from Virginia Beach, Virginia to Culver City, California, a distance of 2,766 miles, is 40 hours via I-40 west.  How much smaller must the United States seem from the driver’s seat of a car than from the bench of a covered wagon? 

The distortion of the landscapes we pass through is ever increasing with the advancement of technology.  The British company Centre for Process Innovation (CPI) and a different company IXION released designs for windowless planes in 2013 and 2014.  The designs, which are purported to save on fuel, replace traditional windows with internal video screens connected to outside cameras. Beyond a camera’s view of the outside, there could be information displays on things the plane is passing over, entertainment, and even the possibility of video of a different flight that you’d rather see.  If just simple glass can distort your view of the world, how much so will high tech video displays change the view of the Earth below? It’s estimated that windowless planes could come to reality by 2024.

Driving for a solid day to cross the desert of Utah isn’t the same as walking under a brilliant sun across miles of scrabbly desert floor, spending the nights scented by the fragrance of a juniper campfire.  Driving isn’t the same either as riding a horse or guiding a covered wagon. Driving yourself across miles of scorching asphalt is different also from riding casually in a driverless car.

<a href="https://www.earth.com/news/self-driving-cars-back-roads/">Driverless cars</a> are still in their infancy, many being tested rather secretively in places like Phoenix, Arizona.  In some ways though, driverless cars have already crept into our lives when no one was looking. There has been news recently about accidents where driverless cars have killed a pedestrian or rammed into a fire truck parked on the highway.  I have little doubt that technology can increase to make driverless cars safer. Cars can’t get drunk or be distracted by the radio or an errant text message. What we gain in safety though, we may lose in perception of the world around us. A man in a Tesla died in a wreck while his car was in autopilot, was watching Harry Potter while his car plowed into the trailer of a truck in front of him.  

It’s a standard view of road trips that they’re often boring.  However, it’s worth remembering that everything passing by the passenger windows is the big, beautiful and only planet we live on.  Whether you’re a passenger or a driver, you miss the world around you if you’re always watching a video screen.

Virtual reality headsets showing what may be the future of driverless cars show touch screens instead of windows and restaurant suggestions displayed by the car itself.  There is no getting lost, there is no stopping at whatever place you come to first to eat whatever is available. There is no messy, vibrant interaction with the world around us, there is only the clean, electronic interaction with human and machine.  Increasingly technology has taken the role of intermediary between us and the planet we live on, further distorting how we see the planet we are born a part of. Will the future hold a road trip where we enter a car, watch nothing but video screens, chat online for a number of hours and exit the car on the other end with no concept of the scenery passing us by?  Will travel seem like magic in that we enter a sealed container and exit it in a different place with different people and different climate without exerting ourselves in even the minor effort of driving? How different will the Earth seem in an age of driverless road trips and video screen airplanes? If an automated car breaks down halfway to a destination, will the passengers even know where they are and how to get where they’re going?  

There are five levels to automation on cars, level zero is no automation and level five is full automation.  At the moment many cars have level two automation, cars that can park themselves or monitor highway lines but still require drivers.  We’re already feeling the birthing pains of the next level of technology in the accidents caused by drivers who don’t understand how the technology in their cars works.  There is a lot of talk about safety and a lot of discussion on how to make driverless cars viable for everyone. It’s hard to argue that a car driving itself isn’t safer than a drunk driver or an elderly person who can’t see well.  The loss of real perception of the world around us is something more insidious and almost no one is talking about that. How will we know we’ve lost the forest we’re driving through or that the world is too crowded with people when all we’re watching is video screens?  Like the man who underestimated the danger of driving across Utah without water, the stakes are extremely high. We could lose the planet if we ignore it. Jack Turner summed up the all too common view of nature these days in an interview with the <a href="https://www.thesunmagazine.org/">Sun Magazine</a> in 2014:

“Nature is a movie that goes by outside the car window. There’s absolutely no intimacy with it. Intimacy always has to do with the body. It has to do with what you see, what you hear, what you smell, what you touch, what you taste. It’s like sex: you can’t have it abstractly.”

A Canadian study has uncovered another link between air pollution and lung disease. Ozone exposure at birth can raise the risk of childhood asthma by as much as 82 percent, researchers discovered during the long-term project.

"Our findings show that the hazard ratios for ozone measured at birth as a single pollutant showed statistically significant higher risks for development of asthma, allergic rhinitis and eczema," lead author Dr. Teresa To said in a press release. 

The study began in 2006 with the Toronto Child Health Evaluation Questionnaire; the new findings were based on a 10-year follow-up to the initial survey.

Researchers followed 1,881 children from birth to about 17 years old. They found that 31 percent developed asthma, while 46 percent developed seasonal allergies or hay fever. A whopping 76 percent developed eczema. 

The scientists used fixed monitoring stations across Ontario to measure the amounts of various pollutants in the air during the 10-year span, then matched up the children based on the postal zone where they were born. Health conditions were verified using medical records.

Early ozone exposure appeared to raise the risk of asthma by more than 80 percent, and the risk grew with each 10 parts per billion increase. That risk was not seen with nitrogen dioxide or PM2.5.

"The results of our study are important because the study examines the effect of pollution on health outcomes in early childhood, and has the longest longitudinal follow-up of a cohort of school-aged children in Canada,” said To, who is a senior scientist at the Hospital for Sick Children in Toronto.

Children tend to be at higher risk of pollution-related illnesses because their lungs and other organs are smaller and less advanced, and they often spend more time outdoors than adults do, researchers said.

The new study was presented at the <a href="http://conference.thoracic.org/">2018 American Thoracic Society International Conference</a>.

Global communication systems, from 3G and 4G networks to to WiFi and wires, emit electromagnetic radiation. As those networks grow, so does the amount of radiation they produce – and it could be threatening wildlife, a new report suggests.

The verdict comes from <a href="http://www.eklipse-mechanism.eu/">EKLIPSE</a>, a European Commission-funded project that seeks to support scientific research and create links between science and social policy, after the UK nonprofit <a href="https://www.buglife.org.uk/">Buglife</a> requested a review of current information.

After looking at existing research, EKLIPSE identified some major knowledge gaps on how EMR affects invertebrates, vertebrates and plants. Those gaps could be causing researchers to underestimate the effects of EMR on plant and animal life.

“... the existing community of experts in this field is still very limited, and research tends to be focused on only a few specific species or taxa, and certain types of radiations,” EKLIPSE wrote in a web conference report. “The technical set up and conditions in which the studies are undertaken are often questionable, and there are no common standards or methodologies that can be used to compare and/or reproduce the experiments.”

Prior to the web conference, EKLIPSE reviewed 97 peer-reviewed articles to get an idea of what research already existed on EMR. The idea was to get an idea of how much research on EMR exists, and how reliable that research is. Only studies conducted after 2000 were considered.

The review found that communications systems may be threatening wildlife and plants more than previously believed. Powerlines, WiFi, cellphone data networks, TV and radio broadcasts, and radar could all have negative effects on wildlife, reviewers found.

The electromagnetic radiation these networks produce could affect how insects and birds navigate, and negatively affect plant growth, the scientists said.

More worrying are the massive gaps in knowledge. 

During the web conference, researchers pointed out that there are few studies into the positive effects of EMR – should they exist – in addition to the lack of research on negative effects. Studies are also needed into how new frequencies affect living organisms, and whether they are more or less harmful than traditional EMR sources.

When it comes to animals, more lab-based research, studies of animal populations near major EMR sources, cellular studies and a review of older papers are among the studies needed to determine if EMR is threatening wildlife.

The experts who participated in the web conference suggested that researchers create a cross-disciplinary platform to promote better EMR research, organize citizen science projects, improve methods and standardize measurements, and work with government organizations to acquire funding for more research, among other steps.

In the meantime, they said, developers should avoid putting EMR sources in wild areas and provide better education covering the knowledge that does exist about EMR, especially in poorer countries.

“We apply limits to all types of pollution to protect the habitability of our environment, but as yet, even in Europe, the safe limits of electromagnetic radiation have not been determined, let alone applied,” Buglife CEO Matt Shardlow told the <a href="http://www.dailymail.co.uk/">Daily Mail</a>. “This is a classic case of ‘out of sight, out of mind.’”

Scientists in Iceland are not just trapping <a href="https://www.earth.com/news/carbon-capture-profitable-business/">carbon dioxide</a> (CO2) and storing it underground - they have developed a way to solidify the gas and turn it into rocks so that the CO2 will not reach the atmosphere for millions of years.

The Hellisheidi power station is the largest geothermal plant in Iceland, where heat from the Earth is converted to electricity. <a href="http://www.bbc.com/news">BBC News</a> is reporting that Hellisheidi is also the site of a revolutionary approach to carbon capture and storage (CCS). 

The project, which is known as <a href="https://www.or.is/carbfix">Carbfix</a>, was developed by an international team led by Reykjavik Energy. According to BBC News, CarbFix has evolved from an experiment to a permanent solution since trials were first launched in 2014. The technology currently stores a third of the power plant's carbon emissions, with 10,000 tons of carbon removed last year.

The process begins with trapping waste CO2 and dissolving it into water, which is pumped over 3,000 feet into the ground. The CO2 solution ultimately binds with porous basalt and turns into calcites that fill in the pores of the rocks.

With about 130 active and inactive volcanoes, Iceland has the ideal landscape for this CCS process because it is made up primarily of basalt, volcanic rock formed by the rapid cooling of lava. Carbon dioxide easily bonds to the calcium, magnesium, and iron found in basalts, which help the carbon harden into a mineral form.

Professor Sigurdur Gislason told BBC News that the solidification process of captured carbon was predicted to take “decades to thousands of years,” but the team found that it hardened in just around 400 days.

CarbFix geologist Sandra Snaebjornsdottir pointed out to the news outlet that this method of CCS could be implemented anywhere there is water and basalt, which is the most common rock in the world.

“The storage capacity is such that, in theory, basalts could permanently hold the entire bulk of CO2 emissions derived from burning all fossil fuel on Earth,” said Snaebjornsdottir.

<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.

Wildlife tunnels save millions of amphibians

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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.
