Wildfires in the western U.S. have become a growing crisis. They’re lasting longer, burning hotter, and spreading into areas that rarely burned in the past. 



But another danger is rising, beyond heatwaves and droughts. Lightning - sudden, fierce, and incredibly powerful - is becoming one of the biggest wildfire risks.



In the coming decades, scientists warn that lightning will become an increasingly dominant spark for <a href="https://www.earth.com/news/climate-change-is-making-wildfire-smoke-more-deadly/">wildfires</a>, adding to the already mounting risks across the West.



<h2 class="wp-block-heading" id="h-lightning-is-fueling-more-wildfires">Lightning is fueling more wildfires</h2>



Wildfires need a few things to get going: dry fuel, hot temperatures, low humidity, and a spark. <a href="https://www.earth.com/news/lightning-is-changing-the-atmosphere-in-surprising-ways/">Lightning</a> is one of the most powerful natural igniters.



In the western U.S., lightning already causes more than two-thirds of the area burned by wildfires. And now, new research shows that number is going to rise sharply due to climate change. 



Warmer air holds more moisture, which means more unstable weather patterns. Those patterns, in turn, set the stage for more lightning.



A recent study has revealed that virtually all of the western U.S. - 98 percent of the region - will have more days with a greater likelihood of lightning-ignited wildfires starting as early as the 2030s. 



For regions already accustomed to such fires, such as Oregon, Idaho, and Montana, the risk is even greater. As early as 2060, those states may have as many as 12 additional lightning-filled days per summer.



<h2 class="wp-block-heading" id="h-a-model-to-forecast-lightning">A model to forecast lightning</h2>



Traditional <a href="https://www.earth.com/news/climate-models-underestimate-sea-ice-melt-and-global-warming/">climate models</a> don’t really track lightning. That’s why a team of researchers led by Dmitri Kalashnikov built their own system to fill in the gaps.



“The first step was to project lightning,” said Kalashnikov, a research scientist at the <a href="https://www.ucmerced.edu/" target="_blank" rel="noreferrer noopener">University of California Merced</a>. “The typical climate models don’t directly simulate lightning. It’s too small a process.”



The researchers applied machine learning to forecast where lightning would hit based on variables that we can quantify - such as temperature, humidity, and the level of <a href="https://www.earth.com/news/moisture-in-the-atmosphere-causes-extreme-weather-to-last-longer/">moisture in the air</a>. 



The team merged those results with the Fire Weather Index (FWI), a mechanism that was developed back in 1968 to monitor how probable wildfire initiation and spread is from local weather.



The result is a forecast model tailored to the western U.S., designed to project conditions from 2030 to 2060 - decades earlier than most studies, which typically look only to the end of the century.



<h2 class="wp-block-heading" id="h-more-lightning-in-the-northwest">More lightning in the Northwest</h2>



The northwestern states of Idaho, Oregon, and Montana are projected to experience the greatest growth in lightning days. But strangely, they may not experience the most rapid expansion in wildfires. 



Although lightning will grow, the conditions favoring fires (such as extreme heat or dryness) are not expected to worsen as quickly in the Northwest compared to other regions.



That doesn’t mean northwestern states are off the hook. Cloud-to-ground lightning, the kind that hits trees or grass directly, is still expected to rise significantly in those areas.



<h2 class="wp-block-heading" id="h-less-lightning-greater-wildfire-risk">Less lightning, greater wildfire risk</h2>



In contrast, the Southwest - including Colorado, Wyoming, Arizona, and New Mexico - won’t see as much of a jump in lightning strikes. But the fire risk will still climb. 



This is because even a small spark becomes a big threat when the land is extra dry, the heat is intense, and there’s little rain to cool things off.



The researchers found that these southern states are likely to experience the biggest increases in wildfires caused by lightning, despite the smaller bump in lightning activity. That’s because climate change is pushing up the number of fire-prone days overall.



<h2 class="wp-block-heading" id="h-dry-and-wet-lightning">Dry and wet lightning</h2>



Kalashnikov said the next steps could involve separating the kinds of lightning events. “You can’t help but wonder what the future will look like, especially if you dig in and you realize that there’s actually a lot that we don’t understand,” he said.



One key factor will be figuring out how to distinguish between "dry lightning" and "wet lightning." Dry lightning happens without much rain, making it a fire hazard. 



Wet lightning brings <a href="https://www.earth.com/news/heavy-rainfall-poses-extreme-risks-in-the-western-us/">heavy rain</a>, which can reduce fire risk but increase flood danger. Understanding that difference could help emergency services respond more precisely to fire threats.



<h2 class="wp-block-heading" id="h-wildfire-risks-are-rising-fast">Wildfire risks are rising fast</h2>



As climate patterns shift, the West isn’t just getting warmer and drier - it’s getting stormier in a dangerous way. Lightning is expected to spark more fires, and fires are expected to find more dry fuel waiting. It’s a feedback loop that could reshape fire seasons in the U.S.



This isn’t about something that might happen a hundred years from now. The changes are coming within the next few decades - some may already be happening. 



And for the people living in <a href="https://www.earth.com/news/double-hazard-wildfire-zones-identified-in-the-american-west/">high-risk areas</a>, that means more heat, more smoke, and a greater need for preparation.



The full study was published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2025EF006108" target="_blank" rel="noreferrer noopener">Earth's Future</a>.

Lightning will ignite even more wildfires as the climate heats up

Wildfires in the western U.S. have become a growing crisis. They’re lasting longer, burning hotter, and spreading into areas that rarely burned in the past. But another danger is rising, beyond heatwaves and droughts. Lightning - sudden, fierce, and incredibly powerful - is becoming one of the biggest wildfire risks.

The global demand for <a href="https://www.earth.com/news/palm-oil-plantations-tropical-butterflies/">palm oil</a> has resulted in the clearing of large areas of forest in Indonesia. Researchers have found that these changes in land use are causing temperatures to get warmer. The additional heat is not only a threat to plants and animals but could also make the region more susceptible to wildfires.

Palm oil is the most widely consumed vegetable oil on the planet. As the world's largest producer of palm oil, Indonesia has replaced vast areas of rainforest with oil palm plantations. Sumatra has the highest loss of rainforest in the country, and the changes in land use have led to a substantial loss of biodiversity on the island. 

An international team of researchers led by Alexander Knohl and Clifton Sabajo of the <a href="http://www.uni-goettingen.de/en/1.html">University of Gottingen</a> conducted the first-ever analysis to examine the impact that these land-use modifications have on Indonesia's temperatures. The results of their study, which was focused on the Jambi province in Sumatra, showed that the expansion of cash crops has made temperatures rise significantly.

"Land use change from forest to cash crops such as oil palm and rubber plantations does not only impact biodiversity and stored carbon, but also has a surface warming effect, adding to climate change," said Knohl.

The team compared the surface temperatures associated with various types of land cover such as forests, clear-cut land, and cash crops in Sumatra. They used satellite data collected between 2000 and 2015 by NASA, as well as data collected on the ground.

The researchers established that clear-cut land, which is primarily used for agriculture, was up to 10 degrees Celsius warmer than forests. Mature palm oil plantations were 0.8 degrees Celsius warmer than forests, while young palm oil plantations were found to be 6 degrees Celsius warmer. 

"Young palm oil plantations have fewer and smaller leaves and an open canopy, thus they transpire less water. Also, the soil receives more solar radiation and dries out faster," explained Sabajo.

Overall, the average surface temperature in the Jambi province increased by 1.05 degrees Celsius between 2000 and 2015. Some of this warming can be attributed to climate change, but some of it is a direct result of the changes in land use.

Knohl pointed out that "land surface temperature is an important part of the microclimate, which shapes habitat conditions for plants and animals." The authors of the study also warned that this spike in temperatures will lessen the amount of water available over the dry season and make the area more vulnerable to wildfires.

"We think that current land-use developments in Indonesia need to carefully evaluate all aspects of environmental and socio-economic consequences. Land-surface temperature and microclimate should be considered," said Knohl.

The study is published in the <a href="https://www.egu.eu/publications/open-access-journals/">European Geosciences Union journal</a>.

Air pollution in China is impeding the country’s potential for solar energy production as much as total cloud coverage would, according to a new study. 

When it comes to solar energy production, many studies have examined how much a hindrance clouds have on power generation. But a new study conducted by researchers from <a href="https://www.princeton.edu/">Princeton University</a> is one of the first of its kind to look at the role of pollutants. 

China has been looking to rapidly expand its renewable energy production to meet 10 percent of the country’s electricity demands with solar power alone by the year 2030. 

But <a href="https://www.earth.com/news/china-air-pollution-years/">air pollution</a>, especially in the winter, could thwart these efforts, as pollutants in northern and eastern China reduce the potential for solar production by 1.5 kilowatt-hour per square meter per day. 

Heavy pollution from burning fossil fuels and aerosols linger in the sky and block the sun's rays, impeding optimal solar energy production. 

"Developing countries with severe air pollution that are rapidly expanding solar power, such as China and India, often neglect the role of aerosols in their planning, but it can be an important factor to consider," said Xiaoyuan (Charles) Li, the study's lead author.

The study was published in the journal, Proceedings of the National Academy of Sciences and calculates how much solar energy is lost due to heavy pollution. 

To make those calculations, the researchers used a solar photovoltaic performance model and combined that with data from NASA satellites and instruments that analyze aerosol components in the atmosphere. 

The researchers performed nine different analyses spanning from 2003 to 2014, and covered all of China to see how pollution and clouds impacted solar power generation. 

If China wishes to meet its solar power energy goals, then serious considerations will have to be made for reducing pollution and cutting aerosol emissions. Not only does pollution hinder solar potential, but it also can cause many adverse health effects including respiratory disease. 

The researchers hope to expand their focus to other parts of the world including India for their next project .

A new study has found that if greenhouse gas emissions are not controlled, and efforts to mitigate climate change ignored, parts of New York City could be submerged beneath 50 feet of floodwaters by the year 2300. 

The study was conducted by researchers from <a href="http://www.psu.edu/">Pennsylvania State University</a>, who analyzed possible flood heights in the coming years if <a href="https://www.earth.com/news/climate-change-coffee-industry/">climate change</a> remains unchecked. 

If emissions continue at their current rate, a 500-year flood, or a flood that has a 1 in 500 chance of happening every year, could cause water levels in parts of New York City to reach 17 feet or more by 2100 and 50 feet or more by 2300.

The researchers used simulations to predict future flood levels taking into account the history of sea levels and storm surges dating back to the preindustrial era. The simulations also included current and future projected emissions of carbon dioxide. 

If emissions continue to increase without any major effort to hinder them, the rising sea level from the melting of the Antarctic ice sheet could be worse than any previous predictions. 

The researchers note that the melting ice sheet and its effect on rising sea levels are where the real problems lie for coastal cities like New York. 

“If we cause large sea-level rise, that dominates future risks, but if we could prevent sea-level rise and just have the storm surge to worry about, our projections show little change in coastal risk from today during most years,” said Michael E Mann, a professor of meteorology and atmospheric science at Pennsylvania State. 

"While those storms that strike New York City might be bigger and stronger, there may be fewer of them as changing storm tracks increasingly steer the storms away from NYC and toward other regions."

The key lies in preventing sea level rise. If the Antarctic ice sheet is kept intact, storm surges might not have as big an impact on coastal cities.

Extreme weather events attributed to climate change have cost the United States federal government over $350 billion over the past decade to provide disaster relief and insurance, according to a new report from the <a href="https://www.gao.gov/assets/690/687465.pdf">U.S Government Accountability Office</a> (GAO). 

The report comes at the same time that Congress is working to approve funding for <a href="https://www.earth.com/news/americans-climate-change-hurricanes/">hurricane relief</a> after the string of historic hurricanes that hit Texas, Florida, and the Caribbean. 

"Climate change impacts are already costing the federal government money, and these costs will likely increase over time as the climate continues to change," the report said.

Senators Susan Collins from Maine and Maria Cantwell from Washington asked the GAO to conduct a full report on the cost of climate change. 

The report proves that not only will unmitigated changing climate have disastrous effects on our towns cities, but will also be extremely costly to taxpayers as well. 

The GAO was asked specifically to look at the economic impact of climate change and how it would affect the federal government. The report outlines the methods used to estimate the costs of climate change and recommendations for reducing these costs. 

The report includes reviews of 30 studies on climate change and interviews with 26 experts including researchers, agency officials, and consultants selected specifically by the GAO.

Two of the studies had “national-scale information about the economic effects of climate change across multiple sectors and regions in the United States,” according to the report. 

Those two studies in particular show that the costs of climate change will differ from region to region, with some coastal areas facing damages between 4 and 6 billion dollars per year due to storm surges and potential sea level rise. 

"We cannot ignore the impact of climate change," Senator Collins said in a statement. "This nonpartisan GAO report Senator Cantwell and I requested contains astonishing numbers about the consequences of climate change for our economy and for the federal budget in particular."

A recent study has discovered an increase in herbicide levels found in the urine of older adults. 

The study, conducted by researchers from the <a href="https://ucsd.edu">University of California</a>,<a href="https://ucsd.edu"> San Diego</a> found a jump in detectable urine levels of the herbicide glyphosate and its metabolite in Southern California adults between the years 1993 and 2016. 

Used in herbicides for genetically modified crops (GMO), glyphosate’s increased presence in humans further adds the body of the evidence that <a href="https://www.earth.com/news/new-device-will-hunt-gmos-that-escape-into-the-environment/">GMOs</a> may have unforeseen negative repercussions. 

The study used data from the<a href="https://knit.ucsd.edu/ranchobernardostudy/"> Rancho Bernardo Study of Healthy Aging</a>, which had 112 of its participants take a urine sample every clinic visit from 1993 to 2016. 

Of these, 100 were randomly selected for the new study looking at herbicide levels in the urine samples. 

University of California Researchers took the data from the Rancho Bernardo Study and measured levels of glyphosate and its metabolite aminomethylphosphonic acid (AMPA) from the urine samples that were collected over the years. 

Glyphosate levels increased from .24 micrograms per liter from 1993 through 1996 to .314 micrograms per liter in 2014 through 2016. For 70 of the participants with levels above the limit of detection, the researchers found glyphosate numbers at .449 micrograms per liter from 2014 through 2016. 

AMPA levels also increased from .008 micrograms per liter in 1993 through 1996 to .285 micrograms in 2014 through 2016. Levels above the limit of detection reached .401 micrograms per liter in 70 of the study participants. 

These numbers are worrying, especially since levels above the limit of detection were so pronounced and increased over time in a large number of the samples. 

Glyphosate was listed as a probable carcinogen in 2017 by the State of California, and the researchers note that herbicides using glyphosate may cause adverse health effects. 

More research will need to be done to find out of the extent of harm herbicides like those using glyphosate will have on health and wellbeing of humans in the future.

Scientists have now found a direct link between volcanic activity and melting ice sheets. Researchers from <a href="http://www.earthinstitute.columbia.edu/">The Earth Institute at Columbia University</a> examined the environmental impact of ancient eruption events and found that they caused significant melting of the ice sheet which covered Northern Europe during the last ice age. 

"Over a time span of 1,000 years, we found that volcanic eruptions generally correspond with enhanced ice sheet melting within a year or so," said lead author Francesco Muschitiello.

The researchers analyzed ice cores and meltwater deposits from times that coincided with volcano explosions. Despite the fact these <a href="https://www.earth.com/news/satellites-predict-volcanic-eruptions-2/">eruptions</a> were occurring as far as a thousand miles away, the ice sheets were still impacted by ash falling from from the sky. The ash turned the ice a darker color on contact, which caused the ice to absorb more solar heat than usual.

"We know that if you have darker ice, you decrease the reflectance and it melts more quickly. It's basic science," said Muschitiello. "But no one so far has been able to demonstrate this direct link between volcanism and ice melting when it comes to ancient climates."

Muschitiello’s team investigated a time period ranging from 13,200 to 12,000 years ago, when the last ice age transitioned into today's climate. They focused on eruption events similar to the 2010 eruption of Iceland's Eyjafjallajökull volcano. While the eruption itself was relatively minor, its massive ash cloud was severe enough to shut down air traffic across Europe for almost a week.

Glaciologist and study co-author James Lea said it is difficult to calculate exactly how much melting a volcanic eruption of that magnitude could cause. "It depends on many factors,” he said.

Thousands of model simulations produced by the team revealed that the amount of glacier melting depends on the individual eruption, which season it occurs in, the snowpack conditions at the time, and the elevation of the ice sheet. 

"Change any one of these and you would get different amounts of melt," said Lea. 

The worst scenarios predicted that ash accumulation would melt between 20 centimeters and nearly a meter of ice from surface portions of the ice sheet. Muschitiello said that these preliminary findings indicate that "present day ice sheets are potentially very vulnerable to volcanic eruptions.”

Previous research has suggested that melting glacier sheets could actually increase the frequency of volcanic eruptions by lightening the weight on Earth’s crust and allowing magma to rise. If this link between volcanic activity and melting ice is confirmed, there may be a positive feedback loop between the two, by which eruption events trigger melting ice and the melting ice causes more eruptions.

The study is published today in the journal <a href="http://www.nature.com/ncomms/">Nature Communications</a>.

Salt lakes can be found all over the world and are important to their local communities for both environmental and economic reasons. 

These lakes provide habitats for animals and protect humans from dust storms as long as they’re full. Otherwise, salt from dry lake beds kicks up into the air and can cause a variety of respiratory diseases.

Famous salt lakes like the Great Salt Lake in Utah and the Dead Sea in Jordan and Israel are even considered substantial tourist attractions, and also provide minerals for cosmetic industries. 

Despite the important roles that salt lakes play, recent research has found that they are currently shrinking at drastic rates. A new study revealed that the Great Salt Lake in Utah has lost almost fifty percent of its area. 

The <a href="https://www.earth.com/news/officials-worry-historically-low-level-great-salt-lake/">Great Salt Lake</a> is worth $1.32 billion a year, which puts more pressure on researchers to understand exactly what is happening to these lakes. 

The new study, conducted by several researchers from Utah and Montana, examined how the Great Salt Lake and other saline lakes are impacted by climate change and an increasing demand for water usage. 

The results were published in the journal Nature Geoscience and show that over the past 160 years, water development and agriculture has caused the Great Salt Lake to gradually lose 50 percent of its area and drop eleven feet.

This decline has created more dust storms and degraded natural habitats for the populations of migrating birds that feed and nest in the area. 

“Although the lake has risen and fallen with droughts and floods in recent decades, the persistence of water diversions has decreased the lake's level about 11 feet and exposed a lot of lake bed. The state's plans to continue developing water in the basin will only worsen the problem,” said Wayne Wurtsbaugh, the study’s lead author.

The researchers note that significant conservation efforts and water reductions will be necessary to restore saline lakes across the globe.

Sugar cane harvest

Brazil’s sugarcane crop gets larger every year, and that could be good for the planet.

Sugarcane has become one of the South American country’s top crops – not to use for sugar to be used in food, but to convert into ethanol. That crop has the potential to reduce global carbon dioxide emissions by more than 5 percent, according to an analysis led by Dr. Stephen P. Long of the <a href="http://illinois.edu/">University of Illinois</a>.

Maximizing that potential would take work, said the research team, which included scientists from Brazil’s <a href="http://www5.usp.br/english/?lang=en">University of Sao Paolo</a>. Land use would need to make room for more cane, first of all, they said – fields totaling the size of Texas and California together.

But the sugarcane crop could be expanded without encroaching on environmentally sensitive areas or cutting into crops of human, the researchers said. 

"We've kept the proposed sugarcane production within the area that can be legally converted," Long said in a press release.

The team came to their conclusions by developing a new model to study Brazil’s sugarcane and other agricultural production. They took into account how sugarcane crops behave in various types of soil, with varying amounts of rain, and in other environmental conditions found around the country.

"Most models used to predict future crop production are statistical models that really don't take full account of the way changes in water, carbon dioxide and temperature interact to aect sugarcane production," Long said. "We've used a mechanistic model here that grows the plant, so it's driven by the factors that the plant is responding to on an hourly basis."

They also took into account that Brazil uses every part of the sugarcane crop – even the stem residue is used to power the mill that extracts the ethanol – and the higher efficiency of sugarcane versus corn in producing ethanol.

Converting more of Brazil’s agricultural land to ethanol production could go a long way toward helping the world reach the goals set by the <a href="http://unfccc.int/paris_agreement/items/9485.php">Paris agreement</a> in 2015, which includes working to keep global temperatures no more than 2 degrees Celsius higher than in pre-industrial times. 

Expanding Brazil’s sugarcane crop – and returning fallow sugarcane fields to production in places like Hawaii, the Caribbean and other regions – could put a large dent in that goal, the researchers said.

"The only way we're going to get there is to have a massive reduction in net CO2 emissions," Long said. "No single solution will get us there. We'll need to implement a whole series of incremental steps. We're trying to point out that this could be a very important increment, and one that could be realized in a timely manner.”

The analysis has been published in the journal <a href="http://www.nature.com/nclimate/">Nature Climate Change</a>.

Cool roofs are light-colored surfaces that reflect heat instead of absorbing it into your home. As a result, they keep your home cool and help reduce energy costs. But now, a new study has found that cool roofs can also help save water as well.

Researchers at the <a href="http://www.lbl.gov/">Department of Energy’s Lawrence Berkeley National Laboratory</a> found that cool roofs reduce the amount of water needed for outdoor lang irrigation. 

The study, published in the journal Nature Communications, used climate simulations of 18 California counties over 15 years and included geographical and meteorological data to see how much of an impact widespread cool roof adoption would have. 

“You might not do cool roofs just to save water, but it's another previously unrecognized benefit of having cool roofs. And from a water management standpoint, it's an entirely different way of thinking - to manipulate the local climate to manipulate water demand,” said Pouya Vahmani, one of the study’s researchers. 

The results showed that cool roofs installed on all buildings in Los Angeles County alone could save up to 83 million gallons of water per day. Other counties also showed reductions of four to nine percent in water used for irrigation. 

Cool roofs reduce the ambient air temperatures, and as a result, lawns and yards need less water, reducing the amount needed for irrigation.

The study also found that water conservation measures in areas with drought might save water, but they also can raise temperatures in urban areas. 

In one of the simulations run by the researchers, stopping all irrigation in the San Francisco Bay Area caused a mean daytime warming of one degree Celsius. 

Cool roofs, according to the study, would be an efficient way to help mitigate rising temperatures and reduce the urban <a href="https://www.earth.com/news/reducing-heat-islands-climate-change/">heat island effect</a>, where heat gets trapped in cities.

“These results show that the warming signal from strategies that focus only on outdoor water-use reductions can meaningfully offset the cooling effects of a major heat mitigation strategy, such as citywide cool roof deployment,” the researchers added.

All-natural, non-GMO, fair trade, gluten-free, lactose-free, low-calorie, cage-free, organic. Food labels are meant to help consumers make healthier choices, but do they?

Not always, according to researchers led by the <a href="http://www.udel.edu/">University of Delaware</a>. Some of the foods sporting such labels are no healthier than other snacks or treats. Other foods are healthy, but overlooked because they lack a label.

The problem is that too many labels have loose regulations or little science behind them, the economists found. But because they sound good, they can make customers feel like they’re buying healthy food and ignoring unhealthy choices when that’s not actually the case.

"That has me worried about the poor and those who are food insecure, because now you're trying to make everything a high-end food choice,” said Dr. Kent Messer, the study’s lead author and an expert on environmental and agricultural economics. “And frankly, we just want to have healthy food choices, we don't need to have extra labels that scare away people."

Messer was joined by Dr. Marco Costanigro of <a href="https://www.colostate.edu/">Colorado State University</a> and Dr. Harry M. Kaiser of <a href="https://www.cornell.edu/">Cornell University</a>. The three economists reviewed 90 studies about how food labels affect customers’ perception of products. 

Food labels like “organic” and “fair trade” describe the process of how the food is produced, not the overall outcome for diners’ health, the researchers said. However, shoppers who haven’t learned all of the meanings behind these so-called process labels may not realize that a gluten-free cookie can be just as unhealthy as one that uses wheat-based ingredients – or even more.

Which doesn’t mean the labels are all bad.

“The good part is that process labels can help bridge the trust between the producer and the consumer because it gives the consumer more insight into the market," Messer said in a press release. "New products can be introduced this way, niche markets can be created, and consumers, in many cases, are willing to pay more for these products.”

The downside, though, is that customers in a rush for time and with too much information may grab a food item labeled “natural,” thinking that means it’s organic or free of genetically modified organisms. But that’s not what the label means.

And sometimes, labels ride a trend that people think is good, but may not be. The locavore movement is an example. While is some cases, eating locally raised food is good for the environment – it cuts down on transport-produced greenhouse gases, for example – it’s situational.

Messer offered the example of tomatoes. Creating an artificial environment that would allow them to grow in Canada actually uses more energy and creates more waste than shipping them from Florida, he said.

Backlashes against genetically engineered food has led to fewer investments in agricultural science and fewer options for a growing global population in need of food, he added. Similarly, if people have access to what they believe is “safe” food, clearly labeled, they stop pushing for standards and regulations that make all foods safe, the researchers wrote.

The researchers don’t expect food companies to stop using process labels anytime soon. They’ve divided their study into three portions – the good, the bad and the ugly – to highlight ways in which labels are useful, and ways they are not. For example, labeling water “gluten-free” is not only not useful, because water doesn’t contain gluten normally, but it makes some shoppers suspicious of unlabeled water.

Instead, the researchers had three recommendations for making labels more useful and less damaging to the food industry: First, have mandatory labeling only when a product has been shown to harm human health. Second, governments should not ban process-based food labels, because when used correctly, they can help shoppers learn more about their food. Third, food companies should provide information to help shoppers decipher labels, perhaps through something like a smartphone app. 

The study has been published in the journal <a href="https://doi.org/10.1093/aepp/ppx028">Applied Economic Perspectives and Policy</a>.

Coffee is one of the most popular drinks in the world, ranking only below tea as the most consumed beverage in the world. 

It’s a 20 billion dollar industry, and it’s everywhere. You can find coffee at your local grocery store, in your local cafe, and ready to be served at your favorite restaurant, even though the beans were most likely grown halfway around the world. 

Coffee’s popularity is no surprise, but what is surprising is how fragile and susceptible coffee trees are. 

According to Hanna Neuschwander of <a href="https://worldcoffeeresearch.org/">World Coffee Research</a> in an interview with <a href="https://www.washingtonpost.com/graphics/2017/business/the-race-to-save-coffee/?undefined=&amp;utm_term=.34e01c9d1d15&amp;wpisrc=nl_headlines&amp;wpmm=1">Washington Post</a>, the demand for coffee will double by 2050, but climate change, disease, and pests will reduce the amount of land suitable for growing coffee by half. 

The <a href="https://www.earth.com/news/coffee-consumption-lower-death/">coffee</a> industry will be in serious jeopardy if more is not done to help make the coffee bean hardier in the face of a changing climate. 

The coffee plant needs particular conditions to thrive and dry after being harvested. Too much rain or a dry heat wave could wipe out entire crops or give rise to disease and pests like nematodes and coffee rust. 

Coffee comes from either arabica beans or robusta beans, and because of this exclusivity, farmers have been “inbreeding” plants for generations. This is yet another reason why the coffee tree is so delicate. 

While other crops like corn and soybeans are constantly being improved upon, coffee farmers often lack the means to invest in technology that could help protect their livelihood. 

World Coffee Research was formed as a response to these concerns about the future of coffee and are currently at the head of some exciting scientific advancements that could help save coffee. 

A new plant called an F1 hybrid was described by the <a href="https://www.washingtonpost.com/">Washington Post</a> as a kind of “super plant” that could offer high yields, would be more resilient, and wouldn’t lose any of the rich flavors we have come to know and love with coffee. 

Centroamericano is one of the few F1 hybrids that are currently on the market, but again, lack of resources make distribution and planting the hybrids difficult for local coffee farmers. 

World Coffee Research is aware of these problems and will continue to work to find coffee solutions before it’s too late.

A global analysis of greenhouse gas (GHG) emissions has revealed that CO2 levels have stalled for the third consecutive year. While <a href="https://www.earth.com/news/rising-co2-emissions-mean-protein-deficiency-millions/">CO2 emissions</a> are still the most predominant, these emissions slowed down in 2012 and stalled over the three years that followed.

The assessment, which is conducted by the <a href="https://ec.europa.eu/jrc/en">European Commission Joint Research Centre</a> (JRC) and the <a href="http://www.pbl.nl/en/">Netherlands Environmental Assessment Agency</a> (PBL), is based on the continuous monitoring of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) across the globe.

The study showed that Russia, China, Japan, and the United States continued to lower CO2 emissions. Emissions in the European Union (EU) remained the same as the previous year, and India's emissions continued to increase.

While the main source of CO2 emissions is industry, the primary source of CH4 and N2O emissions is agriculture. Because data on energy-related activities is updated more often than data on agricultural activities, levels of methane and nitrous oxide are only available up until 2012 in the report. 

In addition to not being released as frequently, measurements of CH4 and N2O emissions are also not as precise as estimates of fossil carbon dioxide emissions. Data through 2012 shows a steady increase in overall global GHG emissions, with an increase of 91 percent from 1970 to 2012.

In the EU, six countries account for 60 percent of the CH4 and N2O emissions - Germany, UK, France, Poland, Italy and Spain. The rise in methane and nitrous oxide emissions is also apparent in the United States, China, Japan and India.

On the other hand, the EU has steadily decreased its CO2 emissions over the last two decades, which represent two-thirds of the EU's total greenhouse gas emissions.

The evaluation is based on the JRC's Emissions Database for Global Atmospheric Research (EDGAR), which is exceptional in its space and time coverage and also in its completeness and consistency of data on emissions of greenhouse gases, air pollutants, and aerosols. The report contains fact sheets for 216 countries that cover various emissions from 1970 to 2016.

<h2 class="wp-block-heading" id="h-invisible-threat-in-urban-air">Invisible threat in urban air</h2>



City dwellers face an unseen danger with every breath. New findings from Emory University researchers suggest that fine particulate matter from <a href="http://earth.com/news/traffic-related-air-pollution-might-increase-alzheimers-risk/" target="_blank" rel="noreferrer noopener">vehicle emissions may significantly elevate the risk of developing Alzheimer's disease</a>. The study examined brain tissue samples from 224 individuals who had confirmed diagnoses and volunteered their brains for scientific research.



<h2 class="wp-block-heading" id="h-disturbing-connections-emerge">Disturbing connections emerge</h2>



Scientists analyzed neuritic plaques — protein clusters that characterize Alzheimer's — while mapping each participant's exposure to PM2.5 particles based on residential location and surrounding traffic density. The correlation proved more alarming than anticipated. Individuals experiencing higher pollution exposure showed nearly double the likelihood of elevated plaque accumulation in brain tissue.



<h2 class="wp-block-heading" id="h-timing-matters">Timing matters</h2>



The research team discovered that pollution exposure during the final year before death demonstrated the strongest association with brain changes. This timeline suggests relatively rapid impacts from environmental toxins on neural health. The connection remained robust even after accounting for various demographic and health factors.



<h2 class="wp-block-heading" id="h-genetic-vulnerability-patterns">Genetic vulnerability patterns</h2>



Perhaps most concerning, people lacking the APOE gene—which naturally predisposes individuals to Alzheimer's — exhibited more than twice the susceptibility to pollution-related brain damage. Study author Dr. Anke Huels noted this indicates environmental elements like air contamination could trigger the disease in cases where hereditary factors don't explain.



<h2 class="wp-block-heading" id="h-public-health-implications">Public health implications</h2>



These findings, published in <a href="https://www.neurology.org/" target="_blank" rel="noreferrer noopener">Neurology</a>, underscore the critical importance of air quality regulations in urban planning. The research suggests that implementing stricter emission controls and promoting alternative transportation could serve as powerful tools in Alzheimer's prevention.



As cities worldwide grapple with growing traffic congestion and aging populations, this study highlights an urgent need for comprehensive approaches to environmental health that protect both our lungs and our minds.

<h2 class="wp-block-heading" id="h-hidden-waters-beneath-ancient-craters">Hidden waters beneath ancient craters</h2>



Scientists have made a startling discovery that challenges everything we thought we knew about <a href="https://www.earth.com/news/saturn-moon-mimas-has-remarkably-young-ocean/" target="_blank" rel="noreferrer noopener">Saturn's moon Mimas</a>. Beneath the heavily cratered surface that earned it the nickname "Death Star" lies a global ocean that formed just 5 to 15 million years ago—a remarkably young age by cosmic standards.



<h2 class="wp-block-heading" id="h-cassini-data-reveals-orbital-secrets">Cassini data reveals orbital secrets</h2>



The discovery, led by Dr. Valéry Lainey of the <a href="https://observatoiredeparis.psl.eu/" target="_blank" rel="noreferrer noopener">Observatoire de Paris</a>, emerged from careful analysis of <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>'s Cassini spacecraft data. By studying subtle irregularities in Mimas's orbit around Saturn, researchers detected the gravitational signature of liquid water hidden 20 to 30 kilometers beneath the moon's icy shell.



<h2 class="wp-block-heading" id="h-an-unlikely-ocean-world">An unlikely ocean world</h2>



At only 400 kilometers in diameter, Mimas seemed like the least likely candidate to harbor a subsurface ocean. Unlike other ocean moons such as Europa and Enceladus, which show clear surface signs of internal activity, Mimas displays no obvious hints of the liquid water beneath its ancient, crater-scarred exterior.



"Mimas is a small moon, and its heavily cratered surface gave no hint of the hidden ocean beneath," explained Dr. Nick Cooper from <a href="https://www.qmul.ac.uk/" target="_blank" rel="noreferrer noopener">Queen Mary University of London</a>, a study co-author.



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



The ocean's recent formation makes Mimas a prime target for studying how oceans develop and potentially support life. This discovery adds another member to the exclusive club of ocean worlds in our solar system, each offering unique insights into the conditions necessary for habitability.



The research, published in <a href="https://www.nature.com/" target="_blank" rel="noreferrer noopener">Nature</a> journal, demonstrates how advanced orbital analysis can reveal hidden features of celestial bodies, opening new possibilities for understanding ocean formation throughout the cosmos.

<h2 class="wp-block-heading" id="h-when-earth-became-a-frozen-wasteland">When Earth became a frozen wasteland</h2>



Imagine Earth as a giant snowball, frozen solid from the North Pole to the equator. This wasn't the plot of a science fiction movie – it was our planet's reality 700 million years ago during an extreme ice age that has puzzled scientists for decades.



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



Australian researchers from the <a href="https://www.sydney.edu.au/" target="_blank" rel="noreferrer noopener">University of Sydney</a> have finally cracked one of geology's greatest mysteries: what caused the Sturtian glaciation and why it persisted for an unprecedented 57 million years. This period occurred long before dinosaurs roamed the Earth, when no complex plants or multicellular animals existed.



Dr. Adriana Dutkiewicz, the study's lead author, describes a world completely unlike today's climate. "Imagine the Earth almost completely frozen over," she explained. "The planet was blanketed in ice from poles to equator, and temperatures plunged."



<h2 class="wp-block-heading" id="h-the-combination-of-climate-factors">The combination of climate factors</h2>



The research team discovered that this massive freeze resulted from a "double whammy" of geological events. First, plate tectonic activity reduced volcanic carbon dioxide emissions to historically low levels. Volcanic activity typically releases CO2 into the atmosphere, creating a greenhouse effect that keeps Earth warm.



Simultaneously, weathering of volcanic rocks in what is now Canada actively absorbed atmospheric CO2, further reducing greenhouse gas concentrations. When atmospheric carbon dioxide levels dropped below 200 parts per million – less than half of today's levels – glaciation engulfed the entire planet.



<h2 class="wp-block-heading" id="h-modern-climate-implications">Modern climate implications</h2>



Published in the journal <a href="https://pubs.geoscienceworld.org/geology" target="_blank" rel="noreferrer noopener">Geology</a>, this research provides crucial insights into Earth's climate system. While geological climate changes occur over millions of years, the study emphasizes that human-induced climate change is happening at a pace ten times faster than previously observed natural changes, highlighting the urgent need to understand our planet's delicate climate balance.

</div><figcaption class="wp-element-caption">Greenland is not sinking. In fact, it is the opposite.</figcaption></figure>



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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

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.

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."
