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.

A UN meeting in Kenya may prove to be the beginning of the end of unloading plastic waste into the ocean. Over 200 countries signed a document to show their support for eliminating ocean dumping.

While the statement is a much-needed step toward major change, no concrete plans have been set forth for the action. Many of the countries did, however, make new commitments to reduce <a href="https://www.earth.com/news/crustaceans-ingesting-plastic-ocean/">plastic waste</a>, pledging to take measures such as bans on plastic bags.

Scientists and ambassadors across the globe are hoping the outcome of the meeting will lead to a legally binding treaty. 

Norway's Minister for Climate and Environment, Vidar Helgesen, presided over a UN meeting on plastics and other ocean pollutants earlier this year and has been leading the debate.

Helgeson told <a href="https://www.reuters.com/">Reuters</a>, "There is very strong language in this resolution. We now have an agreement to explore a legally binding instrument and other measures and that will be done at the international level over the next 18 months."

The meeting was organized by the <a href="http://web.unep.org/newscentre/un-declares-war-ocean-plastic">United Nations Environment Programme</a> (UNEP), who reports that more than 8 million tons of plastic makes its way into the ocean each year. UNEP explains that this is “equal to dumping a garbage truck of plastic every minute.”

UNEP also warns that, at the current rate of plastic dumping, the oceans will have more plastic than fish and 99 percent of seabirds will have ingested plastic by the year 2050.

Dr. Li Lin, the Chief Conservation Director of WWF China, told <a href="http://www.bbc.com/news">BBC News</a>, "Today we have seen quite good progress on marine litter and microplastics.”

She added, “We would just like to see this agreement implemented by governments, business, NGOs and consumers as quickly as possible. Because this issue is urgent."

The Clean Seas Campaign is a global UN Environment initiative that was launched in February 2017 with the goal of engaging governments, businesses, and individuals in the fight against pollution in our oceans.

“Marine plastic litter is a rapidly increasing threat to marine life, seafood safety and negatively affects the lives of people in coastal areas all around the world,” said Helgeson. “We encourage every country in the world to join the Clean Seas campaign and develop effective measures to avoid single-use plastic ending up in the environment. Our oceans cannot wait any longer."

To take the Clean Seas pledge and learn more about what you can do to take action against marine pollution, visit the Clean Seas campaign <a href="http://cleanseas.org">homepage</a>.

Dust may seem like just a messy nuisance, but it actually provides vital nutrients to trees in the southern Sierra Nevada Mountains, even more so than the bedrock beneath them. 

As most kids are taught in school, trees and plants typically get their nutrients from the soil. Roots buried deep in the Earth absorb important nutrients and water, and photosynthesis provides energy for the plants to grow and thrive. 

But a new study found that certain mountain-top trees, like those in the <a href="https://www.earth.com/image/sierra-nevada-snowpack-intact/">Sierra Nevada Mountains</a>, depend on windborne dust for nutrients as well. 

The study, conducted by researchers from the <a href="http://www.uwyo.edu/">University of Wyoming</a> (UW) and published in the journal Science Advances, reveals that the trees receive more than 50 percent of their nutrients from dust compared to nutrients provided in the bedrock. 

Lindsay Arvin, a UW Master's student who led the research, took live pine needle samples from trees in the Sierra Nevada. 

Arvin and her colleagues then processed the samples, testing for nutrients from bedrock and dust. 

“We used two fingerprints to trace the nutrients. Dust has one isotopic fingerprint, and bedrock has another isotopic fingerprint,” said Cliff Riebe, an associate professor in UW’s Department of Geology and Geophysics. “Pine needles show the degree of mixing of the two fingerprints. Soils also show a mix of the two.”

This shows that dust is an essential component of mountain eco-systems no matter the nutrient supply in the bedrock below. 

After the researchers examined nutrients in the Sierra Nevada, they expanded their research to examine the importance of windborne dust in other ecosystems around the world. 

The UW research team used two datasets, a global database of erosion rates and a global model of dust inputs, to test the role of dust as a nutrient provider on a global scale. 

“This combination of previous datasets allows us to see where dust is important in the world,” Riebe says. “One surprising finding is dust may be more important than previously thought in a lot of places, including the Appalachian Mountains and Western Europe.”

The results also shed light on the delicate balance that is Earth’s critical zone. 

Earth’s critical zone supports all terrestrial life on Earth. It extends from the top of the tree canopy to the bedrock below. It’s a complex system of water, soil, rock, and vegetation that make up most of Earth’s ecosystems. 

“This research shows that dust transported in the atmosphere around the world is an important source of nutrients for plants in all environments, even where its contribution isn’t obvious,” said Richard Yuretich, program director for the <a href="https://www.nsf.gov/funding/pgm_summ.jsp?pims_id=500044">National Science Foundation’s Critical Zone Observatories Program</a>, which funded the study. “Earth maintains its balance, often in surprising ways.”

Last winter, the state of California experienced more rain from October to February than it had in over 100 years. Marine biologists from the <a href="https://serc.si.edu/">Smithsonian Environmental Research Center</a> have discovered that the record-breaking season took its toll on some marine species in the San Francisco Bay.

"As you get wetter and wetter, there are fewer and fewer [marine] species that can tolerate those conditions," said the study’s lead author, Andrew Chang. 

Chang has been observing invasive species in the San Francisco area since 2000. Chang is particularly interested in aquatic animals like tunicates and bryozoans that grow on boats, docks and fishing equipment. Though some of the creatures are visually stunning, they destroy fishing nets and clog gear.

Chang has noted that some species need the salty water of the bay to survive. When a wet winter sets in and brings large amounts of freshwater into the bay, these types of organisms suffer. 

Extreme changes in the climate like the years of drought in California leading up to the wet winter of 2016 are predicted to become more common with climate change. In the past, scientists have tracked how these shifting weather patterns affect certain species.

Chang and his team examined how San Francisco's fouling community as a whole changed over 13 years of wet, dry, and average weather. The team tracked the growth of these species in Richmond Marina, a mostly saltwater marina in northeastern San Francisco Bay, beginning in 2001. 

The study revealed that when bay waters remained salty during the dry years, the invasive tunicate Ciona robusta dominated. This translucent filter feeder from Asia has invaded five continents, including North America's West Coast. Due to its rapid growth, the species is known for crowding out other species.

When wetter winters occurred, however, the Ciona and similar tunicates were unable to withstand the massive influx of fresh water, and mat-like colonial tunicates and encrusting bryozoans took over in their place.

Chang says that freshwater years reset the system, which will work to the advantage of some invasive species.

"If you're a new invader arriving to San Francisco Bay, for example, what better time to come in than right after a wet winter has killed off most of your potential competitors?" he said.

Chang's team observed a couple of native species that thrived in wet years as well, indicating that wet seasons could be used to benefit native species.

The study is published in <a href="http://onlinelibrary.wiley.com/journal/10.1111/(ISSN)1365-2486">Global Change Biology</a>.

How do jaguars, hamburgers and border walls relate to each other?

Beef is usually not thought of as sustainable. Yet there has been some progress towards making beef a more sustainable enterprise.

In a world where ‘sustainable’ has become the gold standard of buzz words, we must ask, ‘Is sustainable enough?’ Is sustainable beef good for jaguars? Basically something being sustainable means that it can go on for the long term; however you define ‘long term’. Sustainable beef means it has only sustainable inputs, there aren’t finite resources being used for the creation of your hamburger. Sustainable resources are those like water and sun, resources that aren’t going to run out in the foreseeable future. Things get a little murky here though. If water is being pumped from an aquifer that fills at an extremely slow rate, it becomes a less sustainable source of water. If solar panels are made in an intensively fossil fuel dependent process, they’re less sustainable. Is sustainable enough?

Even in a truly sustainable beef production model, things don’t necessarily bode well for big predators. Long have predators been the bane of the rancher. Wolves were villainized throughout the US partly because they were blamed for cattle death. Wolves and their place in the western US is still incredibly contentious. The place of jaguars in the west is on even rockier terrain than that of wolves.

In 1963 a hunter shot a big cat which he thought was a big bob-cat; it turned out the man had killed a jaguar. The jaguar was heralded as the last jaguar in the US, the end of an era. Since that time, other jaguars have been seen crossing the US Mexico border but no evidence of a US breeding population has been found.

Some say, so what? Jaguars wander into the US occasionally and wander out. Their home is further south, not in most of North America. However, it’s hard to deny that historically the jaguar didn’t have a much larger home range, extending further into the US.

In Mexico as in the US, ranchers do not like jaguars. Jaguars have been poisoned and shot for as long as European cattle have been threatened by the big cats. One jaguar with a radio collar was burned to destroy evidence. Recently I saw hope of that changing. At a talk at a Tucson REI, the Northern Jaguar Project expounded on their relationship with ranchers. NJP has started paying ranchers for photos; photos of live predators. Jaguars caught with camera traps on ranchers land pay the most but there is also a reward for ocelots, bobcats and mountain lions. In the US the government and other organizations have offered reimbursement for predation by wolves and other protected predators. NJP however is the first example I know of with positive reinforcement. The project is small but it’s growing, trying to recruit and sign contracts with more ranchers even as they expand the size of a more traditional reserve.

North of the border there is no positive incentive for ranchers to abstain from killing jaguars. Then again, there aren’t a lot of jaguars in the US and making true of the threatened border wall won’t help anything. An almost negligible amount of beef in the US comes from Central and South America, so the hamburger you’re eating isn’t necessarily the problem. Beef isn’t the problem with the jaguar’s current situation. With climates trending warmer, there is the potential of more conflict between jaguars and American <a href="https://www.earth.com/news/california-start-regulating-gas-emissions-cows/">cattle ranchers</a>, then that burger becomes something else. It’s my view that we shouldn’t be happy with keeping the world as it is but should be involved in making things better; better for jaguars as well as humans.

A new study from the <a href="https://carnegiescience.edu/">Carnegie Institution For Science</a> has found that climate models that project more severe warming are the most accurate according to observation of the current climate conditions. The research suggests that climate models used by the Intergovernmental Panel on Climate Change are underestimating future warming.

<a href="https://www.earth.com/news/climate-change-ice-storms/">Climate</a> model simulations are used to forecast future warming for any given increase in the concentration of greenhouse gases in the atmosphere.

"There are dozens of prominent global climate models and they all project different amounts of global warming for a given change in greenhouse gas concentrations, primarily because there is not a consensus on how to best model some key aspects of the climate system," explained study co-author Patrick Brown.

Climate models based on current emissions indicate that global temperatures will rise between 3.2 to 5.9 degrees Celsius over preindustrial levels by the end of the century.

The researchers set out to determine whether the upper or lower end of this temperature range is more likely to happen. The team started out their investigation based on the idea that climate models are the most useful when they precisely represent conditions of the recent past. 

The experts compared model simulations and observations of patterns of energy flow from Earth to space. The study revealed that the models that best represent recent  energy exchanges between the planet and its surroundings project warming that is greater than average. 

The findings of the study eliminated the lower end of the temperature range forecast by raw climate models. The results indicated that future average global warming will most likely be 0.5 degrees Celsius greater than what has been projected.

"Our results suggest that it doesn't make sense to dismiss the most-severe global warming projections based on the fact that climate models are imperfect in their simulation of the current climate," said Brown. "On the contrary, if anything, we are showing that model shortcomings can be used to dismiss the least-severe projections."

The uncertainty in predicting future warming is mostly due to discrepancies in the ways that models simulate changes in clouds. The cooling effect caused by clouds as they reflect the sun’s energy away from the planet is shown by some models to increase and by other models to decrease.

"The models that are best able to recreate current conditions are the ones that simulate a reduction in cloud cooling in the future and thus these are the models that predict the greatest future warming," said Brown.

"It makes sense that the models that do the best job at simulating today's observations might be the models with the most reliable predictions," added study co-author Ken Caldeira. "Our study indicates that if emissions follow a commonly used business-as-usual scenario, there is a 93 percent chance that global warming will exceed 4 degrees Celsius by the end of this century. Previous studies had put this likelihood at 62 percent."

The research is published in the journal <a href="https://www.nature.com/nature/">Nature</a>.

Cities are beginning to turn to <a href="https://www.earth.com/news/easy-ways-adopt-zero-waste-mindset/">composting</a> as another means of keeping waste out of landfills, which also creates a nutrient-rich material that can be used for farming.

Composting comes with many benefits, but now new research has found that composting can lead people to make more eco-conscious decisions in their day to day lives. 

The study was led by Nicole Sintov, an Assistant Professor of Behavior, Decision-making and Sustainability at the <a href="https://www.osu.edu/">Ohio State University</a>. 

Sintov was interested to see if the adoption of a composting program would encourage area residents to make other smart “green” decisions” as part of something called “spillover.” 

Spillover is a concept where one behavior leads to another, either with positive or negative chain effects. For example, someone who decides to eat a salad for lunch might overcompensate for dinner. 

Sintov wanted to explore how spillover would apply to residents of Costa Mesa, California who in 2015 were given the option of curbside recycling and compost. 

“The idea is if you're investing all these resources - composting bins and trucks and new facilities - is it possible that this could lead to any other pro-environment behavior, or do people start to slack off in other areas, which we don't want,” said Sintov. 

The study included 284 Costa Mesa residents who were asked about three food-waste prevention behaviors and seven energy and water-waste behaviors, such as unplugging electronics and taking shorter showers. 

The results showed an increase in water and energy conservation behaviors that correlated with the start of the composting program. Composting was a catalyst that motivated other eco-friendly decisions. 

The researchers were happy to see that the spillover was largely positive. 

Sintov and her colleagues found that because those people that composted were actively engaged in waste disposal, they were more consciousness of waste in other aspects of their lives. 

“Our study found that this happened because waste was on their minds, or 'cognitively accessible,' and this thinking about waste seems to lead you to manage waste in other ways,” said Sintov. 

The study does not represent a wide range of residents, as the participants for the study all came from one affluent and well-educated community. The researchers note that further studies will need to be done to see if the results are duplicated in different communities and populations. 

Even with this in mind, the results present convincing evidence that composting programs have added eco-friendly benefits beyond reducing waste in landfills.

Cancer becomes an ever increasing risk as we age, and the association of old age with many cancer types has been well established. But scientists have also noticed that cancer incidence is increasing globally, and certain geographical populations seem to be at higher risk than others. Populations living in very low temperatures, such as Denmark and Norway, have some of the highest incidences of cancer in the world.

A recent paper published in the journal <a href="https://academic.oup.com/mbe">Molecular Biology and Evolution</a> has proposed a new hypothesis for this phenomenon: there is an evolutionary relationship between adaptation at extreme environmental conditions and increased cancer risk. 

“The findings of this study provide evidence that genetic variants found to be beneficial in extreme environments, can also predispose for cancer,” says Kostantinos Voskarides of the <a href="https://www.ucy.ac.cy/medical/en/">University of Cyprus Medical School</a>.

In his research, Voskarides focused on the effect of low temperatures at either high altitudes or in Arctic/Scandinavian climates. He used the GLOBOCAN-2012 database – the most accurate and reliable datasource for worldwide cancer incidence – and analyzed genetic clues in 247 different cancer genome-wide association studies. Voskarides also looked through the available literature’s bibliographic cancer incidence and genetic data for human populations in extreme cold and at very high altitudes.

The results showed a clear pattern, with the highest incidence of certain cancers linked to populations living in the coldest environments. 

“These data show that these populations exhibit extremely high cancer incidence, especially for lung, breast and colorectal cancer,” explained Voskarides.

Genetic evidence also showed that genes that are under selection to populations in order to survive in extreme conditions are also predisposed for cancer. The highest cancer associations with genes under selection were found to be colorectal cancer for Native Americans and Siberian Eskimos, esophageal cancer and lung cancer for Siberain Eskimos, leukemia for Oromi (a high-altitude population in Ethiopia) and a number of cancers for high-altitude dwelling Andeans-Tibetans.

“Evidence was found that cancer rates have been increased in those populations through natural selection procedures,” says Voskarides. “This is the first study that provides evidence that high cancer risk may be a result of evolutionary adaptation in certain environmental conditions.”

The ultimate conclusion of this study was that populations that are isolated in extreme environments also face extreme <a href="https://www.earth.com/news/cancer-cases-modifiable-risk-factors/">cancer</a> risk. Further research will help better understand the key adaptive forces that may be behind cancer epidemiology.

Fast-moving wildfires are raging across southern California, forcing the evacuation of tens of thousands of people. The Thomas Fire in Ventura County, which broke out on Monday and now covers at least 65,000 acres, is by far the largest. Over 150 buildings have been destroyed and 12,000 additional structures are currently threatened in Ventura alone.

In Los Angeles County, two separate fires ignited on Tuesday. North of downtown <a href="https://www.earth.com/news/watering-lawns-lost-gallons-water/">Los Angeles</a>, the Creek Fire burned 11,000 acres by Tuesday night, and the Rye Fire scorched 7,000 acres. 

A third fire, the Skirball Fire, erupted this morning near the Getty Center as a brush fire. This latest blaze has prompted evacuations from the Bel Air area and shut down portions of Interstate 405 because the fire is burning so close to the highway.

California Governor Jerry Brown has declared a state of emergency in both Ventura and Los Angeles counties, and is urging residents to be ready to evacuate and to “evacuate immediately if told to do so.”

Officials are warning that the fires could threaten the region for days. Los Angeles police chief Charlie Beck referred to the fires as “a multi day event,” and suggested that more fires are likely. 

The National Weather Service warned that the combination of low humidity and strong winds could lead to “very rapid fire growth” and “extreme fire behavior.”

Chief Ralph M. Terrazas of the Los Angeles Fire Department said earlier today that wind conditions are favorable at this time but warned that could change. Santa Ana winds are projected to reach 80 miles per hour on Thursday.

Just two months ago, Northern California experienced the worst series of wildfires in the state’s history, which killed 44 people and burned 8,700 structures.

Wildfires explode across Southern California

Fast-moving wildfires are raging across southern California, forcing the evacuation...

Experts from the UK and the United States are outlining the best investments in clean energy based on their analysis of recent research and innovation. The authors of the paper recommend that governments give technical experts more control of <a href="https://www.earth.com/news/green-solar-panels-appealing/">clean energy</a> programs in order to achieve more long-term stability.

The researchers have drafted six "guiding principles,” and are encouraging the support of programs that have staying power rather than just “ quick win” potential. Among the principles proposed by the research team are to adopt an adaptive learning strategy and to keep clean energy research funding predictable and stable.

"As the window of opportunity to avert dangerous climate change narrows, we urgently need to take stock of policy initiatives around the world that aim to accelerate new energy technologies and stem greenhouse gas emissions," says Laura Diaz Anadon, Professor of Climate Change Policy at the <a href="https://www.cam.ac.uk/">University of Cambridge</a>.

The authors are urging policymakers to learn what works from experience and build on it before time runs out. The experts say that some government officials are constantly reinventing clean energy goals and targets for the sake of political vanity.

"If we don't build on the lessons from previous policy successes and failures to understand what works and why, we risk wasting time and money in a way that we simply can't afford," says Anadon.

Public investments in energy research have steadily risen in recent years. For example, funding for new energy research and development by the Organization for Economic Cooperation and Development (OECD) jumped to $16.6 billion in 2016 compared to $10 billion in 2010. In addition, the EU and other nations pledged to double clean energy investment as part of Paris Climate Change Agreement.

Regardless, the study authors point out that government funding for energy innovation has become highly volatile in the recent past. Political shifts in the UK and the U.S. have resulted in huge budget fluctuations and process reinventions.

The research team found, for example, that one in five technology areas funded by the U.S. Department of Energy experienced a budget shift of more than 30 percent up or down every single year from 1990 to 2017. In 2018, the Trump administration plans to cut the energy research and development budget by 35 percent across the board.

In the UK, every Prime Minister since 2000 has created new institutions to manage energy innovation. 

"Experimentation has benefits, but also costs," explains Anadon. "Researchers are having to relearn new processes, people and programs with every political transition - wasting time and effort for scientists, companies and policymakers."

"Rather than repeated overhauls, existing programs should be continuously evaluated and updated. New programs should only be set up if they fill needs not currently met."

The research is published in the journal <a href="https://www.nature.com/nature/">Nature</a>.

Experts advise governments on effective clean energy strategy

Experts from the UK and the United States are outlining...

As climate change is projected to increase the frequency of severe ice storms, concerns are growing about how forest health will be impacted. Ecologist Lindsey Rustad of the <a href="https://www.fs.fed.us/">USDA Forest Service</a> set out to closely examine how ice storms affect the forest.

It is well-known that <a href="https://www.earth.com/video/artificial-ice-storms-severe-weather/">ice storms</a> can cause damage to communities as large frozen tree limbs can take down power lines and crash into houses, but the long-term damage that ice storms cause to the forest itself is relatively unknown.

Rustad teamed up with New England scientists to simulate an ice storm at the 8,000-acre USDA Forest Service Hubbard Brook Experimental Forest in New Hampshire. The researchers used fire hoses to pump water from a creek over different sections of the forest. 

"It's not easy to study ice storms because they're difficult to predict," explained Rustad. "We didn't want to become storm chasers, so we decided to make our own."

Using various amounts of water, the team created a light icing with a quarter-inch of ice,  a significant icing of a half-inch of ice, and an extreme icing with three-fourths of an inch of ice.

The team will compare the frozen sections of forest to nearby forest area that has not been disturbed. They plan to focus their comparison on forest health indicators including soil nutrient cycling, forest regrowth, and wildlife. The research will contribute to an ongoing decades-long investigation on how a severe ice storm in 1998 affected the northeastern United States and Canada.

Although the project will not be completed until next year, Rustad has some predictions about what her team will discover. She explained that a light icing can be good for forests by thinning out branches and making room for new growth.

"Trees have a certain amount of stored carbon," she says. "With one icing, they have enough reserves to re-foliate and recover."

Severe icing events back to back like scientists have predicted to occur with climate change, however, can be devastating to a forest's carbon reserves. Despite this, Rustad still remains optimistic about the outcome.

"Our forests are tremendously resilient," said Rustad. "I grew up in the days of acid rain. So scientists embarked on a couple decades of exhaustive research and we passed the Clean Air Act, and reduced sulfur emissions by 80%."

During their research, the experts will develop a more accurate climate prediction model that will incorporate extreme ice events. They will also examine the forest health indicators, and hope to innovate new methods of warning the public about upcoming ice storms.

Rustad presented preliminary details of the research project at the October Annual Meeting of the <a href="https://www.agronomy.org/">American Society of Agronomy</a>, Crop Science Society of America, and Soil Science Society of America in Tampa, Florida.

Scientists are warning that <a href="https://www.earth.com/news/heavy-air-pollution-nuclear/">air pollution</a> in London is negatively impacting the health of unborn infants. The experts have determined that exposure to pollution generated by vehicles is associated with an increased risk of low birth weight babies born at full term.

While previous research has linked air pollution with complications in pregnancy, similar studies investigating the potential effects of noise pollution have been inconclusive.  

Researchers led by the <a href="https://www.imperial.ac.uk/">Imperial College London</a> set out to examine the outcomes of exposure to air pollution and noise pollution from road traffic during pregnancy. They focused their study on two potential birth weights, low birth weight and being born small for gestational age.

The research team used national birth registers to identify over 540,000 full-term births in the London area between 2006 and 2010. The experts estimated the average monthly concentrations of traffic-related air pollution at the home addresses of the mothers. They also estimated the average levels of noise pollution during daytime and nighttime hours.

Next, the researchers used statistical models to analyze the data. The study revealed that air pollutants from road traffic, particularly PM2.5, were associated with a 2 to 6 percent increase in the risk of low birth weight and a 1 to 3 percent increase in the risk of being small for gestational age.

There was no significant link found between noise pollution and complications at birth, yet the researchers reported that they "cannot rule out that an association might be observed in a study area with a wider range of noise exposures."

"Our findings suggest that air pollution from road traffic in London is adversely affecting fetal growth," said the study authors. They emphasized that reducing London's annual average PM2.5 concentration by 10 percent would prevent an estimated 90 babies being born with low birth weight at full term each year in London.

"With the annual number of births projected to continue increasing in London, the absolute health burden will increase at the population level, unless air quality in London improves," said the researchers. 

While the authors said that the findings of the study "should increase awareness that prenatal exposure to small particle air pollution is detrimental to the unborn child," they also stressed the fact that increasing awareness without solutions for risk reduction "may serve only to increase maternal anxiety and guilt."

The research, which is published by <a href="http://www.bmj.com/">The BMJ</a>, is applicable to other UK and European cities as well. The experts are urging for environmental health policies to improve air quality in urban areas.

California trees are not just helpful in increasing property value, but also help to clear the air of carbon dioxide and other pollutants. The ecosystem services provided by California’s 173.2 million city trees are valued at $8.3 billion per year. Despite all of these benefits, a new study reveals that California has the lowest canopy cover per capita in the country.

The researchers found that <a href="https://www.earth.com/news/california-psychedelic-mushrooms/">California</a> has 109 square yards of city tree canopy per person, which falls way behind the states with the best numbers such as New Hampshire with 1,514 square yards of tree canopy per person or Alabama with 1,182 square yards of tree cover per person.

Greg McPherson is a research forester with the U.S. Forest Service’s <a href="https://www.fs.fed.us/psw/">Pacific Southwest Research Station</a> and the lead author of the study.

"There's no question that Californians are deriving significant benefits from their urban forests," said McPherson. "However, the fact remains that more can be done and will need to be done in light of the recent tree mortality epidemics plaguing some of our urban forests."

Thousands of trees have been killed in southern California by the invasive shot hole borer. This beetle invades while carrying fungal spores that infect and kill trees, and poses a threat to 33 percent of the urban tree population in the region. Over 50 tree species in southern California are reproductive hosts for the insect, making them vulnerable to its lethal fungus.

Study co-author Natalie van Doorn, a research urban ecologist with the Pacific Southwest Research Station, explained that the state’s population and summer climate are also likely contributors to California’s tree canopy ranking.

"One of the factors driving the low per capita rating for California city trees could be the fact that 20 of the nation's 100 most densely populated cities are in California, meaning there's a higher volume of people in a confined space for trees," said van Doorn. "California's arid summer climate also can suppress tree establishment and growth, which also could be a contributing factor for the results we observed."

Van Doorn pointed out that there are about 236 million vacant tree sites within these California cities, and so there is abundance of space for new trees to be planted.

"In fact, our study results are already being used by municipal and state agencies to identify priority areas for planting and tree conservation, as well as examining potential disparities in disadvantaged communities," she said.

The study, which is entitled "The structure, function and value of urban forests in California communities," is published online in <a href="https://www.journals.elsevier.com/urban-forestry-and-urban-greening">Urban Forestry and Urban Greening</a>.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



The successful demonstration against Xanthomonas oryzae, the pathogen responsible for bacterial blight in rice, represents more than a laboratory achievement. Rice feeds nearly half the world's population, and bacterial blight causes devastating crop losses annually. Traditional control methods rely heavily on pesticides that contaminate soil and water systems.



<h2 class="wp-block-heading" id="h-looking-beyond-disease-resistance">Looking Beyond Disease Resistance</h2>



While disease protection represents the immediate application, the research framework opens doors to broader agricultural improvements. Future developments could engineer microbiomes to enhance nutrient uptake, reducing dependence on synthetic fertilizers. This dual benefit addresses both crop productivity and environmental sustainability.



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



As this technology advances from laboratory to field applications, it promises to reshape sustainable agriculture. The ability to program plants with their own biological defense systems could herald a new era where crops protect themselves naturally, reducing chemical inputs while maintaining yields necessary for global food security.

<h2 class="wp-block-heading" id="h-why-don-t-we-ever-hear-about-acid-rain-anymore-the-environmental-crisis-that-was-solved">Why don't we ever hear about "acid rain" anymore? The environmental crisis that was solved</h2>



Remember the 1980s when acid rain dominated headlines? Dire warnings about rain eating buildings, killing fish, and destroying forests filled every news cycle. Then, almost like magic, acid rain vanished from public discourse. What happened? Did we actually solve one of the late 20th century's most pressing environmental challenges?



The answer might surprise you. Unlike many environmental issues that drag on indefinitely, acid rain represents one of modern history's most successful ecological recovery stories. It's a tale of science, politics, and technology working together to tackle what seemed impossible.



<h2 class="wp-block-heading">What was acid rain?</h2>



Acid rain isn't regular rain having a bad day – it's precipitation that became significantly more acidic due to air pollution. When power plants, factories, and vehicles burn fossil fuels, they release sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere.



<h2 class="wp-block-heading">The science behind it</h2>



Think of acid rain as nature's chemistry experiment gone wrong. These compounds react with water, oxygen, and other chemicals to form sulfuric and nitric acids. When mixed with water vapor in clouds, they create precipitation with dangerously low pH levels.



While clean rain has a pH of about 5.6, acid rain could drop as low as 4.2 to 4.4 – roughly as acidic as tomato juice or coffee. According to US Geological Survey documentation, Scottish chemist Angus Smith first coined "acid rain" in 1872, but it didn't become a household phrase until the 1960s and 1970s when Swedish scientist Svante Odén documented its devastating effects on Scandinavian lakes and European forests.



<h2 class="wp-block-heading">The crisis at its peak</h2>



During the height of public concern, environmental damage was both widespread and visible. This wasn't some abstract future threat – people could see destruction happening in real-time.



<h2 class="wp-block-heading">Environmental devastation</h2>



The most dramatic impacts were impossible to ignore. Research documented by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation shows that in the Adirondack Mountains, more than 200 lakes became so acidic they couldn't support fish life. The Adirondack Council reports that 409 lakes once supported brook trout, but many lost their fish populations due to acid rain.



By 1976, when scientists cataloged all acidified lakes in the Adirondack Park, researchers found that half of the lakes over 2,000 feet above sea level had no fish, according to studies published in environmental journals. The acidification process worked like a slow-motion disaster. As acid rain fell into watersheds, it gradually lowered pH levels. Fish couldn't survive in acidic water, and their food sources died off too.



Trees at high elevations showed stress directly linked to acid rain. It weakened them by leaching nutrients and making them susceptible to disease. Historical records show Germany's Black Forest saw nearly half its trees damaged by the mid-1980s.



<h2 class="wp-block-heading">Economic impact</h2>



Acid rain wasn't just environmental – it was expensive. Acidic precipitation corroded infrastructure, buildings, and monuments. Historic stone structures deteriorated at accelerated rates. Tourism suffered as lakes became fishless and forests declined. EPA economic analyses from the period documented repair costs mounting into billions annually.



<h2 class="wp-block-heading">The solution: government action and technology</h2>



Transformation from crisis to success required unprecedented cooperation between governments, industries, and environmental groups.



<h2 class="wp-block-heading">The Clean Air Act of 1990</h2>



The turning point came with the Clean Air Act Amendments of 1990, signed by President George H.W. Bush. This represented a fundamentally new approach to environmental regulation, as documented in EPA historical records.



<h2 class="wp-block-heading">Cap-and-trade success</h2>



Instead of mandating specific technologies, the 1990 amendments introduced something revolutionary: a cap-and-trade system for sulfur dioxide emissions. EPA program documentation shows this market-based approach set overall limits but allowed companies to trade emission allowances.



The genius was harnessing market forces to find cost-effective pollution reduction. Companies reducing emissions cheaply could sell excess allowances to those facing higher costs. Research published in environmental economics journals and EPA progress reports shows this resulted in dramatic SO2 reduction at a fraction of projected costs.



<h2 class="wp-block-heading">Technology advances</h2>



Policy provided the framework, but technology made reductions possible. Studies in atmospheric science journals document the widespread adoption of flue gas desulfurization systems ("scrubbers") that removed sulfur dioxide before it reached the atmosphere. By the 2000s, new installations could remove over 95% of SO2 emissions, according to EPA technical reports.



The push coincided with cleaner energy development. Natural gas produces fewer sulfur compounds than coal. Wind and solar, emerging in the 1990s, captured growing market share, reducing reliance on high-sulfur coal.



<h2 class="wp-block-heading" id="h-why-we-don-t-hear-about-it-today">Why we don't hear about it today</h2>



Why did acid rain disappear from headlines? Simple: the problem was largely solved.



<h2 class="wp-block-heading">Success doesn't make news</h2>



There's an old journalism saying: "If it bleeds, it leads." Environmental success stories don't generate urgency like crisis reporting. Media attention shifted to other challenges: climate change, plastic pollution, and biodiversity loss. There's only so much environmental anxiety the public can absorb, and newer concerns replaced acid rain.



<h2 class="wp-block-heading">Mission accomplished</h2>



The primary reason is beautifully simple: interventions worked. EPA monitoring data shows sulfur dioxide emissions dropped over 90% since 1990. Academic research published in environmental science journals confirms pH levels in formerly affected areas returned closer to normal. This represents one of history's most dramatic environmental recoveries. Studies by the Adirondack Lakes Survey Corporation show fishless lakes now support healthy populations. Forests recovered, and building damage slowed dramatically.



<h2 class="wp-block-heading" id="h-is-it-really-gone">Is it really gone?</h2>



The crisis is largely resolved, but monitoring data shows the problem isn't completely eliminated – it's managed to acceptable levels. Some areas still experience occasional events during high pollution periods. International environmental research indicates that rapidly industrializing Asian countries face similar problems to what we experienced decades ago, though they're implementing successful strategies.



EPA research shows nitrogen oxide emissions proved more challenging than sulfur dioxide, coming from vehicles and mobile sources. Climate science studies suggest changing weather patterns add complexity to how acid rain forms and falls.



<h2 class="wp-block-heading">What this teaches us</h2>



The acid rain experience proves that seemingly intractable environmental problems can be solved with scientific understanding, political will, and technological innovation. Environmental monitoring data shows recovery speed was remarkable – within a decade, measurable improvements appeared in air quality and ecosystem health.



Success came from bipartisan support across party lines. Policy analysis studies show the market-based approach appealed to those preferring economic incentives while achieving environmental goals. This support created lasting policy surviving political changes.



<h2 class="wp-block-heading">Conclusion</h2>



Acid rain's disappearance from public consciousness represents environmental science's greatest success stories. Through effective regulation, technological innovation, and international cooperation, we transformed an overwhelming crisis into a manageable challenge.



Today's silence isn't because we forgot – it's because we solved it. The 1990 Clean Air Act, combined with technology and energy market changes, reduced acid rain emissions over 90%, according to comprehensive EPA data analysis.



This success offers hope for current challenges. It proves complex problems can be solved when science, policy, and technology work together. As we face climate change and plastic pollution, acid rain reminds us that dramatic positive change is possible.



Next time someone asks whether environmental regulations work, remember acid rain. It's proof that sometimes, we get it right.

<h2 class="wp-block-heading">Frequently Asked Questions</h2>



1. Is acid rain completely gone? No, but EPA monitoring shows it's reduced to manageable levels. US sulfur dioxide emissions dropped over 90% since 1990, making acid rain much less severe than the 1980s crisis.



2. How long did solving take? Environmental monitoring data shows significant improvements began within 5-10 years of 1990s emission controls. Full ecosystem recovery took longer – some areas need 20-30 years for complete recovery.



3. What made the solution successful? Clear scientific understanding, visible damage motivating action, bipartisan support, available technology, and innovative market-based policies like cap-and-trade.



4. Do other countries have acid rain problems? Yes, particularly rapidly industrializing Asian countries. However, international environmental research shows many implement similar successful control strategies.



5. Could acid rain return? Potentially, if regulations weaken or we return to high-sulfur coal without controls, though effects would take years to become severe according to environmental projections.



6. Can you recommend any teaching tools on the subject of "acid rain"? The United States Environmental Protection Agency produced a wonderful teacher's guide for ages 14 and under that you can find on the EPA website here: <a href="https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf" target="_blank" rel="noreferrer noopener">https://www.epa.gov/sites/default/files/2017-03/documents/teachersguide.pdf</a>

A new long-term study in Monkton, Vermont, reveals that wildlife tunnels significantly reduce amphibian road mortality during seasonal migrations. 



Frogs and salamanders often cross roads to reach breeding ponds each spring, but many are killed by vehicles. 



Researchers from the <a href="https://www.uvm.edu/" target="_blank" rel="noreferrer noopener">University of Vermont</a>, in collaboration with local citizens and the Vermont Agency of Natural Resources, installed two underpass tunnels in 2015. 



Over a 12-year monitoring period, they observed an 80.2% reduction in amphibian deaths, and up to 94% for non-climbing species like salamanders. 



The study used a before-after-control-impact design and documented more than 5,200 amphibians, highlighting the tunnels’ effectiveness even in nearby buffer zones.



Funded at $342,397 - far cheaper than wildlife crossings for large mammals - the project showcased the power of community-led conservation.



Local groups initiated the effort after observing mass amphibian deaths. Wildlife cameras later captured over 2,200 amphibians using a tunnel in just one spring, along with other species like raccoons and bobcats, indicating wider ecosystem benefits.



This marks the first peer-reviewed, long-term data set in the northeastern U.S. confirming amphibian-specific underpasses work. 



The study urges transportation departments to incorporate these designs into road planning and highlights how community action, thoughtful infrastructure, and persistence can make a real difference for biodiversity.

Wildlife tunnels save millions of amphibians

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

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Satellites reveal how Earth's systems are interconnected Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes Earth’s interconnected systems, and how this network is affected by rising temperatures.&nbsp;



During 2020, average global temperatures matched the hottest year on record. The hurricane season was also record-breaking, with many of the storms intensifying at extraordinary speeds. Hot water in the ocean is fuel for hurricanes. The satellite data shows that it's all one interconnected system showing how Satellites reveal how Earth's systems are interconnected.



According to NASA, dust swept up from Northern Africa plays a major role in the formation of hurricanes, and is also a key source of fertilization in the Amazon rainforest. As a result of<a href="https://www.earth.com/news/seagrass-wasting-disease-is-fueled-by-climate-change/"> climate</a> change, dust plumes are expected to decline, which will have an effect on vegetation far away.&nbsp;



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth. "Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet.

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."
