For over a century, oil and gas companies have been pulling carbon out of the ground in the form of fossil fuels. Now, researchers are flipping that idea on its head - by putting carbon back underground. And not just anywhere, but into the very same wells that once helped release it.



This new approach doesn’t rely on fancy tech or sci-fi ideas. Instead, it uses leftovers from farms and forests - like corn stalks and tree trimmings - to create a thick liquid called bio-oil. 



Packed with carbon pulled from the air by plants, bio-oil can then be pumped into abandoned <a href="https://www.earth.com/news/abandoned-oil-wells-could-revolutionize-energy-storage/">oil wells</a> for permanent storage.



<h2 class="wp-block-heading" id="h-old-oil-wells-meet-new-solutions">Old oil wells meet new solutions</h2>



Across the U.S., there are hundreds of thousands of old oil and gas wells sitting empty. Many of these wells weren’t properly sealed and now pose environmental and safety hazards. 



Plugging the wells costs about $1 million each. At the same time, tons of plant waste is discarded every year, ranging from corn stover in the Midwest to forest debris in the West. This is where researchers at <a href="https://www.iastate.edu/" target="_blank" rel="noreferrer noopener">Iowa State University</a> saw a match.



“On the one hand, you have these underutilized waste products. On the other hand, you have abandoned oil wells that need to be plugged. It’s an abundant resource meeting an urgent demand,” said Professor Mark Mba-Wright, who led the study.



<h2 class="wp-block-heading" id="h-oil-wells-for-carbon-capture">Oil wells for carbon capture</h2>



The process at the center of the research is called fast pyrolysis. It sounds complicated, but the idea is simple: you heat dried plant bits to extremely high temperatures (over 1,000°F) in the absence of oxygen. 



The result is three products - bio-oil, <a href="https://www.earth.com/news/what-is-biochar-and-how-can-it-help-us-mitigate-climate-change-carbon-storage/">biochar</a>, and gas. The bio-oil captures most of the carbon. The gas helps fuel the system. The biochar can be sold to farmers to improve soil.



“One of the innovations here is that you can do <a href="https://www.earth.com/news/carbon-capture-technology-faces-uncertainty-despite-heavy-investment/">carbon capture</a> with units the size of a skid loader or a combine. You can start small,” Mba-Wright said.



<h2 class="wp-block-heading" id="h-bio-oil-machines-for-the-job">Bio-oil machines for the job</h2>



The team modeled a network of 200 mobile pyrolysis units that could be moved around rural areas to process plant waste on-site. 



Each machine would handle about 10 tons of <a href="https://www.earth.com/news/satellite-view-of-forest-biomass-reveals-hidden-carbon-trends/">biomass</a> daily, producing bio-oil that could be stored in terminals before being transported to empty well sites for injection.



Each unit would cost around $1.3 million to build. According to the study, the system could sequester carbon for about $152 per ton, which makes it cost-competitive with other carbon capture methods. For wood-based materials, the cost could drop closer to $100 per ton.



Filling a single crude oil well requires more than 216,000 gallons of liquid - plenty of space to lock away carbon for good. 



<h2 class="wp-block-heading" id="h-undocumented-oil-wells">Undocumented oil wells</h2>



The researchers estimate that there could be as many as 800,000 undocumented orphaned wells in the U.S., far beyond the 120,000 wells targeted by a $4.7 billion federal cleanup effort passed in 2021.



“The more units they build, the better they would get at building them,” Mba-Wright said. This is thanks to what’s called a “learning rate,” which means that building more machines over time helps lower both production and operating costs.



This isn’t just theory. A San Francisco startup, Charm Industrial, has already started using this method and signed deals with large companies to help them meet climate goals. These companies want carbon-removal credits, and bio-oil injection is emerging as one of the most promising ways to earn them.



"We hear it time and again: after taking a close look among their options, leading carbon-removal buyers find that bio-oil sequestration represents one of the highest-quality and most cost-effective approaches,” said Peter Reinhardt, CEO and co-founder of Charm Industrial.



<h2 class="wp-block-heading" id="h-opportunities-for-carbon-removal">Opportunities for carbon removal </h2>



Charm funded part of the Iowa State study to better understand the technology’s full potential.



“While they were confident about the technology itself, they were looking for some validation of how much <a href="https://www.earth.com/news/mountains-both-carbon-sinks-and-carbon-sources/">carbon</a> could be sequestered and how economical the process could be,” Mba-Wright said. “There are a lot of steps involved in getting this to work at scale.”



One important detail is that this method stacks up well against another popular carbon-removal option - direct air capture. That system also removes carbon from the air, but it’s more expensive to build and doesn’t offer the side benefits of using agricultural waste or creating new revenue for rural communities.



“What we’re trying to show here is that carbon removal doesn’t need to be either/or. There are a lot of opportunities,” Mba-Wright said.



<h2 class="wp-block-heading" id="h-a-win-for-rural-economies">A win for rural economies</h2>



Besides helping the climate, this system could give new life to the rural economy. Farmers could sell their leftover crop waste. Forest managers could get paid to clear wildfire-prone debris. 



Furthermore, small towns could host bio-oil terminals and benefit from new jobs and investments.



"Iowa State’s experts showed that bio-oil sequestration using corn stover can deliver a high-value, durable carbon removal product that outcompetes other technologies, while providing new markets for crop residues and delivering new economic value to the rural economy,” Reinhardt said. 



“As the carbon-removal sector grows, Charm is grateful to work with farm and forest communities to grow this opportunity."



The full study was published in the journal <a href="http://linkinghub.elsevier.com/retrieve/pii/S0196890425005047">Energy Conversion and Management</a>.

Old oil wells are getting a new job - storing carbon

For over a century, oil and gas companies have been pulling carbon out of the ground in the form of fossil fuels.

There are thousands of premature deaths from particle pollution in the United States each year, and the <a href="https://www.epa.gov/">Environmental Protection Agency</a> (EPA) has the responsibility of writing and enforcing regulations that will protect both the environment and human health. Researchers are reporting that the amount of lives saved by legislation from the <a href="https://www.earth.com/news/scott-pruitt-doubts-global-warming/">EPA</a> has been substantially underestimated in the past.

Colette Heald is an associate professor of Atmospheric and Planetary Sciences and Civil and Environmental Engineering (CEE) at the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a>.

“In the United States, the number of premature deaths associated with exposure to outdoor particulate matter exceeds the number of car accident fatalities every year,” said Heald. “This highlights the vital role that the EPA plays in reducing the exposure of people living in the United States to harmful pollutants.”


The 1970 Clean Air Act and its amendments were proposed by the EPA to address the health effects of particulate matter. More specifically, the legislation regulated the emissions of air pollutants and promoted research into cleaner alternatives. 

The EPA reported in 2011 that the regulations set forth in the Clean Air Act had led to a substantial decrease in particulate matter in the atmosphere, and estimated that over 100,000 lives were saved every year from 2000 to 2010 as a result of the enforcement of the new laws. 

The report, however, did not account for organic aerosol, a major component of particle pollution, as a large contributor to the decline in particulate matter during this time frame. Organic aerosol is emitted directly from vehicles, residential burning, and wildfires, and is also chemically produced in the atmosphere from the oxidation of  hydrocarbons.

The research team examined surface measurements of organic aerosol from all over the country between 1990 to 2012, which enabled them to develop a comprehensive map of organic aerosol in the United States.

“Widespread monitoring of air pollutant concentrations across the United States enables us to verify changes in air quality over time in response to regulations,” said Heald. “Previous work has focused on the decline in particulate matter associated with efforts to reduce acid rain in the United States. But to date, no one had really explored the long term trend in organic aerosol.

The researchers discovered that there had been a much more significant decline in organic aerosol than previously thought, which suggested that more lives has been saved by the EPA than what was reported.  

“The EPA report showed a very large impact from the decline in particulate matter, but we were surprised to see a very little change in the organic aerosol concentration in their estimates,” explained study co-author David Ridley. “The observations suggest that the decrease in organic aerosol had been six times larger than estimated between 2000 and 2010 in the EPA report.”

The findings of the study are published in the <a href="http://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

<a href="https://www.earth.com/news/remote-sensing-oil-palm-industry/">Oil palm</a> plantations wreak havoc on forest habitats, but the popularity of palm oil in everything from foods to cosmetics makes conservation policy difficult to regulate or put in place.

Mass deforestation has occurred to make way for oil palm plantations, as the fruit of oil palm trees are where palm oil comes from. 

New research has found that on top of habitat degradation, oil palm plantations also have a surprising effect on boar populations. 

A two-decade-long study, conducted by an international team of researchers led by the <a href="http://www.ntu.edu.sg/">Nanyang Technological University, Singapore</a> (NTU Singapore), found that oil palm plantations provide an easily accessed, rich source of food for wild boars and macaque monkeys. 

This, in turn, causes drastic increases in populations and the surrounding forests are irreversibly damaged. 

The researchers found that saplings and small trees near plantations were reduced by more than half because boar mothers harvest the plants for nests. 

“When oil palms start fruiting, wild boars quickly aggregate to feed in the plantations,” said Dr. Matthew Luskin, a member of the research team. “The abundant food allows them to reproduce, causing a massive surge in their population in the nearby forest. The biggest subsequent effect this leads to is when pregnant wild boars build nests, as this clears vegetation from the forest floor.” 

At first, the researchers were puzzled at the loss of habitat, but after years of field studies, it was obvious that oil palm plantations have a wide-reaching effect not previously realized. 

Future studies are needed to understand the long-term effects of plantations beyond deforestation, and because of how many plantations there are in Southeast Asia, the impact could be devastating. 

The researchers note the need for conservation policy and regulations in order to combat these effects. 

“Through impactful studies on the effect of agricultural expansion and wildlife population, we hope to provide insights for countries and policymakers who seek to protect our environment for future generations better,” said Fidel Costa, an associate professor and Acting Chair of NTU's Asian School of the Environment.

<a href="https://www.earth.com/news/air-pollution-crisis-india/">India</a> has launched a new weapon to combat air pollution. The “anti-smog gun” rapidly shoots out water droplets intended to flush pollutants out of the air. Some experts say this is not tackling the source of the problem and that infrastructural changes are what is really needed.

New Delhi is one of the most polluted regions of the world. Airborne particles and chemicals form toxic smog that lingers over the city, which is home to 19 million people. It has been reported that breathing the air when the smog is at its worst is roughly equivalent to smoking 50 cigarettes a day.

In eastern New Delhi, Anand Vihar is an area which borders an industrial zone and often has the worst quality of air. According to the U.S. Embassy, levels of fine particulate matter known as PM2.5 registered 380 in Anand Vihar, which is more than 15 times the level that the <a href="http://www.who.int/">World Health Organization</a> has deemed as “safe.”

The Department of Environment and the <a href="https://www.dpcc.delhigovt.nic.in/">Delhi Pollution Control Committee</a> are testing out the water mist cannon in Anand Vihar. The machine is hooked up to a water tank and mounted onto a truck, shooting out atomized water up to 230 feet in the air. The goal is to mimic the air cleaning effects of rain and bring dust particles to the ground.

Delhi’s environment minister Imran Hussain said, “If it proves to be successful, then we will roll these out on Delhi’s streets as soon as possible.”

Anumita Roy Chowdhury is Executive Director of the <a href="http://www.cseindia.org/">Centre for Science and Environment</a> (CSE). Chowdhury and other experts have pointed out that the water mist cannon does not provide a long-term solution.

“This can be an instant measure for local effect, especially if there are local gross dust generators,” said Chowdhury. “However, a more sustained and long-term measure is needed to bring systemic changes.”

One of the main concerns of climate change is the increasing prevalence of killer <a href="https://www.earth.com/news/heat-waves-increase-mortality-rates/">heat waves</a>, which will only become more common as the climate warms. But heat isn’t the only issue. 

A new global study states that, with the current trend of climate change, humidity will also increase in many areas and serve to magnify the effects of heat waves. In some cases, these conditions may surpass humans’ ability to work – or in some cases, survive.

Regions that could be affected include the southeastern United States, the Amazon, western and central Africa, southern areas of the Mideast and Arabian peninsula, northern India, and eastern China.

“The conditions we’re talking about basically never occur now – people in most places have never experienced them,” says Ethan Coffel, a graduate student at <a href="http://www.columbia.edu/">Columbia University</a>'s Lamont-Doherty Earth Observatory and the study’s lead author. “But they’re projected to occur close to the end of the century.”

While a warming climate has been predicted to make many currently dry areas even dryer, as global temperatures rise, this same change in precipitation patterns may also allow the atmosphere to hold more water vapor – and thus result in an increase in humidity in some climates. Chronically humid areas along coastlines or linked to humid-weather patterns may become even more humid. 

If you’ve ever been outside in hot and humid conditions, you know that the effects are noticeably less tolerable than hot and dry conditions at the same temperature. This is because we cool our bodies through sweating, where our sweat evaporates off our skin into the air, taking excess heat with it. But when the air is already heavy with moisture, evaporation off the skin slows down – and at a certain point, becomes impossible. When this cooling process is no longer working, our core body temperature rises and results in lethargy, sickness, and possibly death. 

The researchers did their study through using global climate models to map and project future “wet bulb” temperatures, which shows the combined effects of heat and humidity. They found that by the 2070s, high wet-bulb readings that now occur maybe once a year could happen 100 to 250 days per year in some parts of the tropics. Coauthor Radley Horton, a climate scientist at <a href="http://www.ldeo.columbia.edu/">Lamont-Doherty</a>, believes these climate effects could be “transformative” for all areas of human activity – “economy, agriculture, military, recreation.”

Elfatih Eltahir, a professor of hydrology and climate at the <a href="http://web.mit.edu/">Massachusetts Institute of Technology</a> who has studied the issue in the Mideast and Asia, says this new study “is an important paper which emphasizes the need to consider both temperature and humidity in defining heat stress.”

Unless we curtail greenhouse gas emissions, many people will be put at risk of health problems as a result of overheating, and nations’ economies could be severely affected. One silver lining is that, if we substantially cut emissions in the next few decades, we can avoid the worst effects.

Scientists are reporting that snowfall in south-central <a href="https://www.earth.com/news/snowfall-alaska-mountains-doubled/">Alaska</a> has drastically increased thanks to climate change, but not many regions of the world are as fortunate. In fact, diminishing snowfall and rainfall totals across the globe are causing some major issues, both economically and environmentally.

Snowpack is an important component of both recreational and professional winter sports. More importantly, snow provides fresh water for rivers and streams and supplies drinking water in the spring and summer months. In some areas, snowfall is more consistent than others. The following list describes the places in the world that have the most impressive and reliable snowfall totals.

&nbsp;

Chamonix, France

This French resort was the site of the first Winter Olympics in 1924 and for good reason. Chamonix usually gets about 32 feet of snow and the winter season here lasts six months.

&nbsp;

Niseko, Japan

With an annual average snowfall of 49.5 feet, Niseko is undoubtedly one of the snowiest destinations on the planet.

&nbsp;

Nagano, Japan

Nagano is home to a world-renowned ski resort known as Hakuba, which is located in the northern Japanese Alps. Every year, the city gets an average of 36 feet of snow.

&nbsp;

Aomori City, Japan

This mountain town receives an average of 26 feet of snow per year. This good fortune is attributed to the city's location high in the Hakkoda Mountains, and also to its proximity to the ocean.

&nbsp;

Alyeska, Alaska

Winter sports are abundant in Alyeska, where an average of 33 feet of snow falls every year. This ski resort is located about 30 miles from Anchorage.

&nbsp;

Sapporo, Japan

Sapporo hosted the first-ever Winter Olympics in Asia in 1972 and is the capital of Japan's northernmost major island, Hokkaido. The city has an average snowfall of over 19 feet. 

&nbsp;

Toyama, Japan

Located near the Sea of Japan, Toyama is a prime target for Japan's heavy snow belt. The region receives around 12 feet of snow each winter season.

&nbsp;

Syracuse, United States

According to Accuweather, Syracuse University is the second snowiest college campus. This city gets over 10 feet of snow annually, and experiences a major blizzard that dumps about a foot of snow at least once per year.

&nbsp;

Saguenay, Canada

Saguenay is a relatively new town in Quebec, which sees an average of 11 feet of snow per year. Over 92 days out of the year, there is snow on the ground.

&nbsp;

Buffalo, United States

Located on the shore of Lake Erie in upstate New York, Buffalo sees its fair share of massive snowfall including lake effect snow. On average, Buffalo receives approximately 8 feet of snowfall per year.

Some schools take field trips to national monuments or museums, but for a group of students from Glasgow and Ullapool, Scotland, their field trip took the form of a beach cleanup on Isle Martin in Loch Broom. 

The students ended up removing thousands of plastic straws among the washed-up marine pollution. Inspired by their efforts, the village of Ullapool has officially stopped use of plastic straws in bars, restaurants, and cafes. 

The <a href="http://www.bbc.com/news/uk-scotland-highlands-islands-42439946">BBC</a> first reported on the success of the campaign, wherein 14 businesses agreed to either stop using straws or switch to an eco-friendly alternative such as paper straws. 

Students from Ullapool Primary School and Glasgow's Sunnyside Primary School ran the campaign with aid from the <a href="https://scottishwildlifetrust.org.uk/">Scottish Wildlife Trust</a>. 

The decision to go plastic-free was motivated in part by the students’ realization of how harmful plastics are in the world’s oceans. 

There are millions of tons of <a href="https://www.earth.com/news/scientists-find-plastic-in-the-most-remote-parts-of-the-ocean/">plastic</a> floating in the oceans, and millions more added every year. The accumulating plastic harms ecosystems and often form deadly traps for marine wildlife. 

The plastic problem is so dire that according to an <a href="https://www.theguardian.com/business/2016/jan/19/more-plastic-than-fish-in-the-sea-by-2050-warns-ellen-macarthur">Ellen Macarthur Foundation Report</a> presented at the World Economic Forum in 2016<a href="https://www.theguardian.com/business/2016/jan/19/more-plastic-than-fish-in-the-sea-by-2050-warns-ellen-macarthur">,</a> plastic waste could outnumber fish by 2050. 


Everything from takeout containers, microbeads from synthetic fabric and hygiene products, plastic bottles and bags, and countless plastic straws are currently dumped in the ocean and washing up on beaches. 

“There's no need for plastic straws. If you do use a straw it shouldn't be a throwaway one. We're killing our seas with single-use plastic and it's just not necessary,” Caillín Erin Patterson, a student from Ullapool told the BBC. 

The Scottish government has commended Ullapool, noting that it’s a great step forward in reducing marine pollution and keeping shorelines clean.

Experts are reporting that 2018 will not be as hot as its preceding years due to the La Niña weather event which brings cooler temperatures. According to the <a href="https://www.metoffice.gov.uk/">Met Office</a>, the United Kingdom's national weather service, active volcanoes could also contribute to global cooling next year. 

2017 was the third hottest year on record, and 2016 was the <a href="https://www.earth.com/news/2016-hottest-year-record/">hottest</a>. While 2018 will still be among these record hot years, below-average temperatures in the south Pacific will make it relatively cooler.

Experts report that the eruption of active volcanoes could further cool the planet.Professor Adam Scaife is the head of long-range prediction at the Met Office. 

“2018 will be very warm globally but is unlikely to exceed the recent record, set in 2016 – but could be cooled further from volcanic eruptions,” said Scaife. “For example, Bali’s Mount Agung, which has recently experienced modest eruptions, could cause a temporary but significant drop in global temperatures if it undergoes a major eruption in the coming year.”

La Niña has developed over the past couple of months, bringing below-average sea surface temperatures to the Pacific. When these temperatures are cooler than average by at least 0.5 degrees Celsius, along with consistent atmospheric signals, a La Niña is considered to be underway.

La Niña does not have the exact same effects each time it occurs, but there are some indications it is already influencing the northwestern United States. During October and early November, this region experienced below-average temperatures and early low-elevation snow.

Despite the range of uncertainties in forecasting 2018, it will undoubtedly remain among the warmest years on record. Of the 17 hottest years ever documented, 16 of them have occurred since 2000.

If you’re in the habit of only eating egg whites as a means to pack on more protein with fewer calories, you may be costing your muscles. 

A new study conducted by researchers from the <a href="https://www.uic.edu/">University of Illinois</a> found that consumption of egg whites versus whole eggs has a drastically different impact on the muscle’s ability to process protein. 

The study was led by Nicholas Burd, a Kinesiology and Community Health professor and published in the Journal of Clinical Nutrition. 

Egg yolks contain cholesterol, which is also why some people stick to egg whites only. But the yolk also has protein, vitamins, and nutrients that egg whites don’t. 

Furthermore, the researchers found that egg yolks enhance muscle repair and growth. 

“This study suggests that eating protein within its most natural food matrix tends to be more beneficial to our muscles as opposed to getting one's protein from isolated protein sources,” said Burd. 

The researchers had ten men complete a resistance exercise session and then eat either egg whites or whole <a href="https://www.earth.com/news/eating-eggs-increases-growth-children/">eggs</a>. All the participants consumed 18 grams of protein in total. 

The participants were also given infusions of two amino acids, the stable-isotope-labeled leucine, and phenylalanine, so the researchers could measure amino acid levels in blood and muscle after the eggs were eaten. 

The eggs used for the study were developed by the University of Illinois Poultry Research Farm and also had leucine in them. 

Blood and muscle biopsy samples were taken from the study participants several times, and from these, the researchers were able to track the egg-derived amino acids in blood and protein in the muscles. 

At first, it seemed like protein in muscles was not affected by which part of the egg was consumed.

“In each case, about 60 to 70 percent of the amino acids were available in the blood to build new muscle protein,” said Burd. “That would suggest that getting one's protein from whole eggs or just from the whites makes no difference, as the amount of dietary amino acids in the blood after eating generally gives us an indication of how potent a food source is for the muscle-building response.” 

However, when examining protein synthesis in the muscle, the researchers found that the post-workout muscle building response was 40 percent greater for those participants that had eaten the whole egg rather than just the whites. 

We all need protein to maintain a healthy diet, and this study shows that while eating egg whites might be a leaner option, there are specific benefits to be had from eating the yolks too.

Mussels are a popular seafood that are eaten around the world and in many cultures. But this tasty dish may be containing slightly more unnatural ingredients than you would hope.

A new study has found that <a href="https://www.earth.com/news/worlds-tap-water-contains-plastics/">microplastics</a> – which are tiny pieces of plastic less than 5 mm long – are contaminating mussels from the European Arctic to China. 

Researchers from the <a href="https://www.niva.no/en">Norwegian Institute for Water Research</a> (NIVA) discovered that plastic had been found in mussels in Arctic waters, which they believe was being moved north by ocean currents and winds from European and America. Past studies have also found microplastics near countries like China, Chile, Canada, and the UK.

“Microplastics have been found in mussels everywhere scientists have looked,” says Amy Lusher, one of the study’s authors.

Off of Norway, the mussels contained 1.8 bits of microplastic on average. But the mussels in the supposedly pristine Arctic waters had the most plastic of any tested on the Norwegian coast – with 4.3 bits per mussel. 

Although the impact of microplastics on humans and marine life when eaten is not known, researchers have suggested in the past that mussels could be a global bioindicator of microplastic pollution. This is because they live on the seabed – where many plastics end up – and stay in one place. “It’s a warning signal that we need to do something about reducing the input of plastic to the ocean,” says Richard Thompson, a professor and expert on microplastics at <a href="https://www.plymouth.ac.uk/">Plymouth University</a>.

Thompson’s research has shown that extremely high levels of plastics in the seabed can harm animals such as lugworms – which live in the seabed – and build up in their tissues. However, most microplastics pass through the guts of both shellfish and humans, and it is not known if they cause any harm to our bodies. However, this is still a cause for concern simply from the standpoint of how much plastic is filling up our oceans. Whether or not it is detrimental to consume small bits of plastic, we can all agree they don’t belong in the ocean.

Across <a href="https://www.earth.com/news/first-african-turtle-europe/">Europe</a>, countries are legally obligated to improve the energy efficiency of buildings, which basically means that buildings must be transitioned to consume the minimal amount of energy. All public buildings must use nearly-zero energy by January 1, 2019, and all new buildings must achieve this target by January 1, 2021.

"It is only 1 year until the first commitment and yet many countries are a long way from meeting this level of energy efficiency in buildings," explained study co-author Juan María Hidalgo. “The countries that have made the most progress in this challenge are the ones in central and northern Europe.”

The study, which was led by the <a href="https://www.uliege.be/">Université de Liege</a>, was focused on the construction of buildings in seven countries in Southern Europe including Cyprus, France, Greece, Italy, Portugal, Romania, and Spain. 

Differences in the technical definitions of each country make it very difficult to directly compare the nearly-zero energy building (nZEB) regulations. The researchers explained that they “made an effort to reach agreement on a common methodology. It was the only way of making real comparisons on a like-for-like basis.”

The study revealed that there are more than just technical barriers making it difficult to achieve minimal energy usage in the buildings of Southern Europe. The team also identified sociological and climate barriers in each country which are greatly affecting progress toward nZEBs.

"The poor training of practically all the players, starting with the administration, including construction workers, and going right up to citizens, constitutes a huge human chain in which there is still a lack of understanding about what nZEBs are and how to achieve them," explained Hidalgo. 

"If these barriers are not overcome, there will very likely be dissatisfaction with the actual result, since problems of thermal comfort, overheating, unnecessary additional costs in the building, etc. could arise, often exacerbated by the poor functioning of the buildings," said Hidalgo. He added that "the study is proposing improvements in the regulations, design, construction and use for buildings of this type.”

The researchers hope that their report will help to resolve some of the major challenges in developing energy efficient buildings. The findings of the study may enable the countries of Southern Europe “to get to 2020 with a better-prepared building sector, with better tools and greater awareness.” As a result, "it will be possible to build nZEBs that meet the needs of everyone, at the lowest cost and with the least environmental impact possible.”

Southern Europe struggling to achieve energy efficient buildings

Across Europe, countries are legally obligated to improve the energy...

When I was very young, I went on a camping trip with my family and some friends.  We visited an expansive prairie filled ranch of an acquaintance.  The ranch was near Badlands National Park, South Dakota.  In my memory there were piles of fossil bones everywhere.  I collected a tooth that was later identified as a mastodon tooth.  I was mesmerized by the smooth enamel surface, worn on the edge by a live animal chewing.  As a child I imagined I could feel the residual energy of the animal’s life force still inside the fossil.  I would brush my fingers along the varnished surface of bone and imagine the life of an ancient creature.  This feeling and the fascination it spawned lead me down a path that landed me a job working at a museum quality fossil replica studio in western Colorado.

Fossil replication is tedious, exacting.  The basic principle is simple: you make a mold by painting a layer of liquid rubber over a fossil, wait for it to harden and peel it off.  Making the fossil replica then involves pouring liquid epoxy into the rubber and waiting for it to harden, then pulling the replica out of the rubber.  The devil is in the details.  

I remember the delicately curved horns arching over the modestly sized frill of a <a href="https://www.earth.com/news/dinosaur-fossil-racist-nazi-science/">dinosaur</a> skull.  Diabloceratops was aptly named, looking like a horned demon of mythology.  I’ve spent hours trimming the jagged seam lines on casts of ceratopsian skulls from Grand Staircase-Escalante National Monument.  Some of the weirdest, alien looking dinosaurs I’ve worked on in about 8 years in the business have been from Grand Staircase-Escalante National Monument and it’s really no great surprise.  Grand Staircase-Escalante has long been looked at a great ‘science monument’ a kind of giant, natural lab where everything from wildlife to archaeology is looked at.  Some of the world’s most important dinosaur fossils have been found in Grand Staircase-Escalante.

To learn more about paleontology in Grand Staircase-Escalante, I got in contact with Randall Irmis, Chief Curator and Curator of Paleontology at Natural History Museum of Utah.  Dr. Irmis describes himself as a kid who liked dinosaurs and never grew up, right out of grad school for a PhD in Integrative Biology, he got a job at NHMU.  Randall describes the scientific curiosity that lead him and other researchers to Grand Staircase-Escalante,

 “One of my major field-based projects is in Late Cretaceous rocks in Grand Staircase-Escalante National Monument (GSENM), where we are documenting ancient ecosystems on land between ~90 and 74 million years ago.  My collaborators and I are interested in why we find so many unique species in GSENM - does it relate to physical barriers, climate, sea level, or a combination of those factors?  Also, what does it tell us about ecosystem evolution in a greenhouse world?”    

Under Trump’s reduced monument(s) the Kaiparowits Plateau will be cut from National Monument status.  The plateau is the recent site of the excavation of a Tyrannosaur skeleton.  Dr. Irmis tells me about working in the National Monument and what could be lost, “Working in GSENM is a truly spectacular experience.  I love the high desert, and the landscape is beautiful, striking, and stark.  The fossils are really quite abundant, beautifully preserved, and few other places in the United States afford the chance to regularly discover so many new species of ancient animals and plants!  The many moments of discovery make working in GSENM so exciting.  It is incredible to excavate and study new species never before known to science, but literally every fossil we excavate is a visceral experience - as you uncover the specimen its remarkable to think you are the first human to ever lay eyes on this bone, shell or leaf, and the first living thing of any kind to see it in 75+ million years…The areas removed from the monument contain fossil bearing rocks from the Triassic Period (252-201 million years ago) and part of the Cretaceous Period (particularly those from 95-80 million years ago). These include fossils that document the beginning of the age of dinosaurs (Triassic), those documenting marine ecosystems of the Western Interior Seaway and a climate change event that caused a mini-mass extinction in the ocean called 'Oceanic Anoxic Event 2' during the Late Cretaceous (~94 million years ago), and important Cretaceous fossils of early mammals from 90-80 million years ago.”       

On one wall in the fossil casting business hangs a poster.  On the poster is a photograph of a dinosaur trackway.  Tracks with three toes lead through sandstone but end at the edge of a body of water.  The poster reads, “The Lost Trackway” and below that, “Lake Powell”.  The poster is a sad nod to the realities of the west and how land is treated here.  Lake Powell of course is the damming of Glen Canyon, a place that has been spoken of by old timers with the same reverence used for Zion or Canyonlands or Arches.  When Glen Canyon Dam was built sacred Native American sites were flooded; the town of Hite, Utah was destroyed in the deluge and people were uprooted.  A giant sandstone arch was covered by Lake Powell.  Lake Powell has more miles of shoreline than the West Coast of the US.  Imagine the things we don’t even know of covered by Lake Powell.  This time, there isn’t a flood threatening, just the slow, steady wave of development.

What we may potentially lose is priceless.  Dr. Irmis makes the scientific importance obvious.  The curiosity that would drive one to spend a life pouring over fossils from this area is palpable, 

“The paleontological resources of GSENM are truly unique and spectacular.  It preserves fossils from the Late Permian (~270 million years ago) all the way to the Late Cretaceous (~66 million years ago), and nearly every geological layer has significant fossils in it.  Particularly notable are the Late Cretaceous deposits from 95-74 million years ago, where we and others have discovered dozens upon dozens of new species of fossil organisms not found anywhere else on Earth.  These new species include plants, clams, snails, fish, amphibians, lizards, turtles, crocodilians, dinosaurs, birds, and mammals - basically the entire spectrum.  Because they are unique to GSENM, they document ancient ecosystems not found anywhere else in the world, and as mentioned above, are critical to understanding how life on earth responds to greenhouse conditions (i.e., globally warm temperatures, high atmospheric CO2, high sea levels, and no polar ice caps).  As such, they're an important study system for where our Earth might be going in the future…

Although there are abundant and important dinosaur footprint fossils from the Early and Middle Jurassic sediments in GSENM (~200-165 million years ago), all the named species based on skeletal material come from the Cretaceous sediments that are between 95-74 million years old.  Over two dozen new species of dinosaurs have been discovered from this time interval, but only about half of those have been formally named and scientifically described because we have so many new species, and it takes a lot of time to do the research.  Its worth noting that we also have discovered from these same rocks many new species of turtles, crocodilans, amphibians, lizards, and mammals that are also unique to GSENM.  During this time GSENM was a sub-tropical environment similar to the bayous of Louisiana today - a broad floodplain crisscrossed by rivers and streams with cypress-like conifers and other lush vegetation.” 

The threat to the one-of-a-kind fossils in Grand Staircase-Escalante National Monument stands in stark contrast to Trump’s declaration.  In reference to the potential loss of protection on fossil sites of Grand Staircase-Escalante Trump proclaims, “The modified monument boundaries take into account this new information and, as described in more detail below, retain the majority of the high-potential areas for locating new fossil resources that have been identified within the area reserved by Proclamation 6920.”  Really in the end it comes down to: do you really believe this president; or is this just another case of ‘Alternate facts’?

A new study has found that rising temperatures will nearly triple the number of migrants applying for asylum in the European Union. If carbon emissions are reduced and <a href="https://www.earth.com/news/major-coal-company-climate/">climate change</a> is mitigated, the asylum applications are still projected to rise by at least a quarter by 2100.

"Europe is already conflicted about how many refugees to admit," said study senior author Wolfram Schlenker of <a href="http://www.columbia.edu/">Columbia University</a>. "Though poorer countries in hotter regions are most vulnerable to climate change, our findings highlight the extent to which countries are interlinked, and Europe will see increasing numbers of desperate people fleeing their home countries."

Schlenker collaborated with study co-author Anouch Missirian, comparing asylum applications to the EU filed from 103 countries between 2000 and 2014. They observed temperature variations in the home countries of the applicants. 

The analysis revealed that the more temperatures in each country's agricultural region deviated from 68 degrees Fahrenheit during growing season, the more likely people were to seek refuge.

Once the researchers accounted for future warming, they found that an increase of average global temperatures of 1.8 °C would cause a 28 percent rise in asylum applications by 2100. The current rate of global warming  would cause a 188 percent increase in applications by the end of the century.

The research adds to a growing collection of evidence that extreme weather changes can destabilize societies, escalate conflict, and force people to leave their home countries. 


Solomon Hsiang, an economics professor at UC Berkeley who was not involved in the research, referred to the study as an "incredibly important" alert. 

"We will need to build new institutions and systems to manage this steady flow of asylum seekers," said Hsiang. “As we have seen from recent experience in Europe, there are tremendous costs, both for refugees and their hosts, when we are caught flat footed. We should plan ahead and prepare." 

Colin Kelley is a climate scientist at Columbia's International Research Institute for Climate and Society.

"It's unclear how much more warming will occur between now and the end of the century, but the study clearly demonstrates just how much climate change acts as a threat multiplier,” said Kelley. “Wealthier countries can expect to feel the direct and indirect effects of weather shocks from man made climate change in poorer, less resilient countries."


The research is published today in the journal <a href="http://www.sciencemag.org/">Science</a>.

<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.



The study is published in the journal&nbsp;<a href="http://dx.doi.org/10.1038/s41467-023-44335-3" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

<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">

</div></figure>



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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

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.
