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.

When a supermoon rises in the night sky tonight, it’ll be the first – and last – of 2017. The full moon will be closer to the Earth today than it has been at any other time this year, making it appear much bigger and brighter than usual.

A supermoon is classified as a full moon during the period when the moon’s orbit is closest to Earth, a point called the perigee. At its closest point to the Earth on Sunday, the moon will be only 222,135 miles away from Earth. Normally, the moon is about 238,900 miles from our planet.

“Full moons can occur at any point along the moon’s elliptical path, but when a full moon occurs at or near the perigee, it looks slightly larger and brighter than a typical full moon,” <a href="https://www.nasa.gov/">NASA</a> educational tech specialist Lyle Tavernier told the <a href="http://www.dailymail.co.uk/">Daily Mail</a>.

At around 3:45 a.m. on the U.S. East Coast, the moon will be closer to our planet than it’s been since November 2016. 

However, the best time to see the heavenly show will be just after sunset, thanks to a phenomenon known as the “moon illusion.” When the moon is closer to the horizon, it looks larger to the naked eye – if not to cameras. 

To catch the full effect of the supermoon on film (or a memory card), NASA suggests <a href="https://www.nasa.gov/feature/shoot-the-supermoon-like-a-pro">using a telephoto lens</a> and adjusting settings for low light. And, of course, getting away from ambient light sources can help, so for the best photo opportunities head out of cities or towns to rural areas.

The supermoon will begin rising just before 5:30 p.m. on the East Coast, and just before 4:30 p.m. on the West Coast. 

But if you’re not looking skyward when the supermoon rises tonight, don’t worry. Two more are coming in the first month of 2018. Not only will the supermoon on January 31 be a rare “blue” moon – the second full moon within a month – but western North America and Eastern Asia will be treated to a total lunar eclipse the same night, according to NASA.

“The lunar eclipse on Jan. 31 will be visible during moonset, NASA research scientist Noah Petro told <a href="https://www.space.com/38969-supermoon-trilogy-kicks-off-dec-3.html">Space.com</a>. “Folks in the eastern United States, where the eclipse will be partial, will have to get up in the morning to see it.”

Researchers have identified two pesticides that are making songbirds severely ill. Pesticides known as neonicotinoids and organophosphates, which are among the most widely used in the world, have been previously linked to declining bee populations.

Now, biologists have witnessed firsthand just how harmful the <a href="https://www.earth.com/news/pesticides-bumblebees-buzzing/">pesticides</a> are for birds as well. 

A study by researchers at the <a href="https://globalnews.ca/search/university-of-saskatchewan/">University of Saskatchewan</a> is unprecedented in demonstrating the toxic effects of neonicotinoids and organophosphates in birds. The research team fed sparrows varying doses of the pesticides over the course of three days during spring migration.

The experts found that the birds suffered from drastic weight loss and completely lost their sense of direction after ingesting only three or four seeds affected by an insecticide in the class of neonicotinoids known as imidacloprid.

“What surprised us was how sensitive and rapid the effects were, particularly to imidacloprid,” said study co-author Christy Morrissey. “The birds showed a significant loss of body mass and signs of acute poisoning (lethargy and loss of appetite).”

“The migration trials also showed that birds completely failed to orient or changed their northward orientation,” said Morrissey.

Study co-author Margaret Eng said that the team found it encouraging that most of the birds observed in the study recovered after they stopped ingesting the pesticides.

“But the effects we saw were severe enough that the birds would likely experience migratory delays or changes in their flight routes that could reduce their chance of survival, or cause a missed breeding opportunity,” said Eng.

According to Morrissey, the findings of this study could have a major impact on the regulation of these pesticides.

The research is published in the journal <a href="http://www.nature.com/srep/">Scientific Reports</a>.

Earthquakes happen every day. The <a href="https://earthquake.usgs.gov/contactus/golden/neic.php">National Earthquake Information Center</a> actually locates up to 14,000 earthquakes per year, yet most are so small that they go unnoticed. Earthquakes that measure less than a magnitude of 2 happen hundreds of times a day, while earthquakes that measure magnitude 8 and higher occur only about once a year. 

While scientists cannot predict when a large earthquake will happen, they can often pinpoint where these events will strike. The following are the cities which experts believe are the most likely to experience a major earthquake.

&nbsp;

Tokyo, Japan

Tokyo is located on top of the Ring of Fire, an intense region of seismic activity in the Pacific Ocean which is responsible for 80 percent of all strong earthquakes. A study from the University of Tokyo found that the city has a 98 percent chance of experiencing a large earthquake over the next 30 years.

&nbsp;

Jakarta, Indonesia

Also located over the Pacific Ring of Fire, small earthquakes are common in Jakarta. Half of the city is below sea level, making this city extremely vulnerable to flooding or ground liquefaction in the event of a major earthquake. 

&nbsp;

Manila, Philippines

Manila, which is also prone to volcanoes, tsunamis, and typhoons due to its position on the Ring of Fire, experiences frequent earthquakes. Because of its current infrastructure, it is predicted that almost 17 million people will be exposed to damage, death, or injury in the event of an intense earthquake.

&nbsp;

Los Angeles, California

The state of California sits on the San Andreas fault,  a major fault line that forms the tectonic boundary between the Pacific Plate and the North American Plate. Both plates are moving northward, but the Pacific Plate is moving faster, creating a lot of pressure that is likely to be released in the form of a massive earthquake.

&nbsp;

Quito, Ecuador

In this region, the Nazca plate is diving beneath South America. According to the geological survey, the plate is moving eastward at 61 millimeters per year, causing an enormous amount of tension. Ecuador just had an intense magnitude 7.8 earthquake last April. 

&nbsp;

Osaka, Japan

In Osaka, 14.6 million people would be affected by a big earthquake, which is likely to happen due to Japan’s position over the volatile Ring of Fire. A disaster in this city would be catastrophic to the country’s economy, according to experts.

&nbsp;

San Francisco, California

Scientists say that the state of California is 99 percent likely to experience a huge earthquake within the next 30 years. The devastation could be the worst in San Francisco, which is located near the Cascadia Subduction Zone opposite the Ring of Fire. This region is so dangerous that experts warn an earthquake here could reach a magnitude of 9, which only happens once in hundreds of years.

&nbsp;

Lima, Peru

Earthquakes have been a common occurrence in Lima for thousands of years. This is due to Peru’s location over the boundary of two tectonic plates, the Nazca Plate and the South American Plate, which collide a little more each day and release the pressure in the form of earthquakes.

&nbsp;

Tehran, Iran

Scientists warn that a large earthquake expected to hit Tehran will kill hundreds of thousands of people. Seismologists have put the risk of an earthquake of magnitude 6 or greater at 90 percent, and experts say that the area is just too populated to handle this sort of catastrophe.

&nbsp;

Istanbul, Turkey

Istanbul is positioned near the center of the North Anatolian fault zone. The Marmara section of the fault zone which includes Istanbul is known to rupture every 250 years and the last earthquake was in 1766. Scientists say that a massive earthquake could strike any day.

A Canadian fishing crew caught a lobster off the coast of New Brunswick that is truly one-of-a-kind. The lobster has a Pepsi logo plastered across its claw like a tattoo. 

Karissa Lindstrand, the woman that noticed the interesting <a href="https://www.earth.com/news/baby-lobster-numbers-decline-maine/">lobster</a> while it was being loaded in a crate to have its claws banded, drinks Pepsi every day and quickly identified the image. 

There is no telling how the image got there, and some are speculating that the lobster must have grown inside of a Pepsi can. But Lindstrand claims that the picture was pixelated, which means it likely did not originate from a can.

Lindstrand told the<a href="https://www.theglobeandmail.com/"> Globe and Mail</a>, “It looked like the image was tattooed on the lobster claw. I've just seen deformed claws. I've never seen anything like this before with the image of a Pepsi symbol.”

Lindstrand explained that the image was not paper but could be scraped off. 

“I'm still trying to wrap my brain around what exactly it was,” she said. “I just happened to notice a blue picture, and got looking at it closer and it was a Pepsi can.”

The discovery comes at a time when a growing collection of evidence suggests that the pollution in Earth’s oceans is expanding out of control. Researchers are now estimating that between five and 13 millions tons of plastic is being dumped into the ocean every year.

Matthew Abbott is a marine coordinator with the Conservation Council of New Brunswick. He suggested that the lobster claw delivers an important message.

 “What it really tells us is the prevalence of marine debris in our coastal waters,” said Abbott. “This is a case where the lobster not necessarily has been hurt by it, but it shows that even in the relatively deep waters off Grand Manan there’s garbage down there.”

Researchers have determined that an underground commute may be harmful to your health. A study from the <a href="https://viterbischool.usc.edu/">USC Viterbi School of Engineering</a> has found that underground transit routes are likely to contain higher levels of carcinogens in the air.

90 percent of the 4.5 million people that make up the workforce in Los Angeles spend an average of one hour each day commuting. The research team set out to examine potential environmental benefits of different modes of transportation in the <a href="https://www.earth.com/news/watering-lawns-lost-gallons-water/">Los Angeles</a> area.

Using devices with particle sensors, the researchers collected air samples along major commuter routes, including freeways I-110 and I-710, the Metro Red and Gold Lines, as well as Wilshire and Sunset Boulevards. These sites represented a range of traffic and environmental conditions.

Diesel-fueled commercial trucks transporting cargo are frequently traveling on the 710, while the 110 allows only non-commercial vehicles across much of its length. The streets surveyed by the team also have much less commercial traffic. 

In addition, the Gold Line is a light rail that is above ground and the older Red Line travels entirely underground.

The researchers used cancer potency factors obtained from the EPA and California's Office of Environmental Health Hazard Assessment (OEHHA). They calculated cancer and non-cancerous health risks based on a lifetime of exposure commuting one hour a day, five days a week, for 30 years of employment.

The study revealed that the maximum Excess Lifetime Cancer Risk for the Red Line was ten-times higher than the acceptable threshold of one-in-a-million. This was caused by high levels of hexavalent chromium measured in the air of the train cars. The researchers said this was likely due to a buildup of dust resulting from friction on the steel tracks and also due to the lack of ventilation on the underground line. 

The study authors pointed out that the Red Line is the most used of the six Los Angeles Metro lines, accounting for about 40 percent of total commutes on these rail lines annually.

Although the team found some measurable concentrations of hexavalent chromium along the other routes, including inside personal automobiles, the maximum Excess Lifetime Cancer Risk for these routes was found to be within the safety threshold. Overall, the lowest levels of hexavalent chromium and polycyclic aromatic hydrocarbons were found within the Metro Gold Line.

The design of the Red Line, which does not have open windows and has a ventilation system, actually prevented even higher concentrations of carcinogens inside the train cars.

"What we report is actually the absolute, most protective case scenario for the Red Line," said study author Constantinos Sioutas. "The initial premise of our study was to prove that you are better off not driving and instead taking the subway and the light rail. We proved part of the point with the light rail, but we were completely refuted insofar as the Red Line because of the chromium levels.”

The researchers believe that other underground subway systems are likely to have similar issues. They explained that individuals who spend more time in the subway have a higher health risk.


The research is published in <a href="http://www.aaqr.org/">Aerosol and Air Quality Research</a>.

A recent bout of earthquakes in the Fort Worth Basin of Texas occurred on fault lines that have not been active for 300 million years, according to a new study.

Instead, the reason behind the seismic events near Venus and Irving, Texas was <a href="https://www.earth.com/news/oklahoma-earthquake-wastewater-injection/">wastewater</a> injection that has forcibly caused the long inactive faults to move. 

The research was published in the journal Science Advances and led by Beatrice Magnani, a<a href="http://www.smu.edu/"> Southern Methodist University</a> seismologist who analyzed seismic data from different faults and earthquakes. The goal was to differentiate natural earthquakes from human-induced ones. 

“To our knowledge, this is the first study to discriminate natural and induced seismicity using classical structural geology analysis techniques,” said Magnani. 

For the study, Magnani and her colleagues analyzed the history of fault displacement throughout the years. The team examined seismic reflection data that allowed the researchers to map the Earth’s subsurface from reflected, artificially generated seismic waves. 

The researchers also compared data from the Fort Worth Basin to the New Madrid seismic Zone, an area in the Midwest that had a series of major earthquakes in the early 1800s. 

Both the New Madrid Zone and the Fort Worth Basin are currently active with small earthquakes occurring in both places. However, the earthquakes in the New Madrid Zone could hint at a much bigger earthquake in the future. 

The results show stark differences between the two active zones. There is evidence of movement in the New Madrid Zone from activity dating back millions of years, but in the Fort Worth Basin, no similar evidence can be found.  

“These North Texas faults are nothing like the ones in the New Madrid Zone - the faults in the Fort Worth Basin are dead,” said Magnani. “The most likely explanation for them to be active today is because they are being anthropogenically induced to move.” 

The researchers theorize that the likely cause of the human-induced earthquakes is waste-fluid injection. The results pose a strong argument against practices where pressurized fluid and wastewater are injected deep into the Earth.

Scientists are examining the potential of “elasto-gravitational” signals to produce estimates of the magnitudes of large earthquakes. A new study reveals that these small gravity changes, which move at the speed of light, are the earliest indication of the immensity of an earthquake.

Early Earthquake Warning (EEW), which is a system aimed at warning the public of an <a href="https://www.earth.com/news/predicting-large-earthquakes/">earthquake</a>, depends on P waves to carry urgent seismic details. These elastic waves that transport valuable information about earthquake characteristics have been long considered the fastest way to transmit earthquake data. But now, scientists are beginning to dispute this idea.

Martin Vallée of the <a href="http://www.ipgp.fr/en">Institut de Physique du Globe de Paris</a> teamed up with other researchers to examine the perturbations to Earth’s gravitational field, or elasto-gravitational signals, caused by earthquakes and their elastic wave fields. These gravity-induced signals travel at the speed of light, which is much faster than P waves.

In 2011, the Tohoku earthquake and its subsequent tsunami killed thousands of people and caused billions of dollars in damage. The research team analyzed data recorded during this event and found that the gravity changes which reflected the magnitude of this earthquake were being recorded at seismic stations long before seismic waves arrived to be measured.

According to the researchers, a new technique based on elasto-gravitational signals could have alerted people in Japan that the earthquake’s magnitude was higher than 9 in a matter of  minutes. Instead, the 2011 quake was largely underestimated by the Japan Meteorological Agency as having a magnitude of 7.9. Three hours later, the earthquake was still underestimated as having a magnitude of 8.8.

The study is published in the AAAS journal <a href="http://www.sciencemag.org/">Science</a>.

If you’ve been present here on Earth for the last few years, you probably noticed the dramatic increase in the number of extreme weather events and natural disasters around the world. In fact, scientists have determined that in recent decades, there has been a significant increase in the frequency and severity of extreme weather climate-related events worldwide. These events are associated with warming temperatures globally, and include occurrences such as monsoons and droughts in India, the destructive hurricane in Puerto Rico, and major flooding in Houston, Texas. 

With <a href="https://www.earth.com/news/humans-driving-climate-change/">climate change</a> increasing the frequency of these events, it’s important that we better understand how human health can be affected in the long-term by natural disasters. Increased understanding may help to develop more effective approaches for planning and response. This was the goal of a recent study published in the <a href="http://www.tandfonline.com/loi/uawm20">Journal of the Air &amp; Waste Management Association</a>.

Dr. Jesse Bell of <a href="https://ncics.org/">North Carolina Institute of Climate Studies</a> and colleagues stress that properly preparing for a disaster response should entail understanding the many complex ways in which these events affect human health. Immediate injuries are one obvious factor, but there are other indirect or delayed health effects that are often overlooked, including mental health impacts.

The authors warn that as the climate changes, planning for these disasters based on historical examples alone will be unlikely to provide the complete picture of potential health threats. With climate change becoming more of a factor, historical norms alone aren’t going to be sufficient for linking extreme weather events to long-term health outcomes.

It is suggested that healthcare facilities should work to determine their vulnerabilities in local infrastructure in order to be fully prepared for a natural disaster. Issues such as overcrowding, loss of power, reduction of staff, and problematic location could play a major part in exacerbating short and long-term health problems. 

“Some of the associations between extreme events and health are already understood,” the authors say. “But many opportunities exist for exploring additional linkages and pathways.” Along with further research, there should be an increased effort to coordinate institutional, government, and private sector programs in order to help with recovery after a natural disaster as assist in rebuilding necessary infrastructure, while also supporting the public.

There are nearly 70 species of sea snakes in the world that can be found everywhere from the South Pacific to New Zealand to Central America. 

Over time, sea snake species have become specially adapted to their aquatic surroundings. They have flat tails that help them maneuver through the water, they can hold their breath, and go for months without taking a drink. 

"Sea snakes have evolved to survive in a way that is completely different than turtles, crocodilians or freshwater snakes,” said Coleman Sheehy, the <a href="https://www.floridamuseum.ufl.edu/">Florida Museum of Natural History</a> herpetology collection manager. “Nothing else does it like sea snakes - they've made fascinating adaptations to overcome the huge number of difficulties associated with surviving in the ocean and are by far the most successful marine reptile group.”

But even though sea snakes are found far and wide in the Pacific and <a href="https://www.earth.com/news/new-dead-zone-indian-ocean/">Indian Oceans</a>, there is a major body of water where the creatures have yet to appear: the Atlantic Ocean. 

This is especially perplexing because extinct species of sea snake once lived in the Atlantic and today, sea snakes could hypothetically thrive in the Caribbean.

A new paper, co-authored by researchers from the <a href="http://www.ufl.edu/">University of Florida </a>and published in the journal Bioscience, examines the lack of sea snakes in the Atlantic and suggests some possible answers.

Sea snakes began to evolve 6 to 8 million years ago and many species first appeared 1 to 3 million years ago. But before the snakes could move to regions in the Atlantic, the only safe means of traveling to the Caribbean, via the Isthmus of Panama, had been blocked off. 

Today, places where passage is possible, such as over the tip of South Africa, are too cold and dry for the snakes to survive the journey.

Sea snakes rely on warmer waters and freshwater for drinking, and so the chances of any sea snake species making it to the Caribbean are slim. 

The authors of the paper also discuss the threatened status of some sea snake species. According to the authors, even if warmer waters made an Atlantic crossover possible, the negative impacts of climate change would more than likely cause many sea snake species to die out. 

Population declines are currently underway among several sea snakes specices. 

“I think one of the reasons we're seeing declines in certain populations is because of changing rainfall patterns,” said lead author Harvey Lillywhite. “If rainfall patterns aren't conducive to providing water to drink, sea snakes can't survive, even if ocean temperatures are favorable. The availability of freshwater is going to be a huge factor in understanding local extinctions.” 

Sea snakes are an important part of the ecosystem and their evolutionary adaptability is unmatched. If populations are already facing decline due to climate change, it does not bode well for their continued survival.

<a href="https://www.earth.com/news/cold-winter-weather-later/">Winter</a> is coming in the Northern hemisphere, and for many colder places that means the arrival of snow and ice – always a hazard for drivers and pedestrians alike. However, new research published in <a href="http://www.tandfonline.com/loi/laps20">Applied Spectroscopy Reviews</a> suggests an improved, safer method for dealing with dangerous icy roads.

Researchers have detected a substance known as hydrohalite that forms on icy roads and can be very problematic for drivers. Because it does not respond to de-icing or road surface salting, hydrohalite usually stays on the road. Although it isn’t visible to the naked eye, this substance presents a major threat to all drivers if left untreated.

In order to test for a solution to removing hydrohalite, Dr. Rolf W. Berg – associate professor in the <a href="http://www.dtu.dk/english">Technical University of Denmark</a>’s Department of Chemistry – and colleagues recreated the conditions under which hydrohalite forms. During their experiments, they found that this substance can be easily detected by using Raman instruments, which are small laser devices that can identify the structure of a molecule and the presence of a substance.

If Raman instruments were installed in salt-spreading trucks and snow plows, either an automated system or the driver would be able to determine where the substance needs to be removed. In doing so, they could switch to a more appropriate de-icer for hydrohalite removal, which would consist of one mixed with sand and gravel.

“Equipping salt-spreading trucks with Raman detectors - essentially small boxes which would sit underneath the vehicles - would be a relatively straightforward solution,” says Berg, “potentially reducing the number of road traffic accidents and even saving lives.”

With millions of car accidents occurring in the U.S. alone each year, finding ways to improve road safety and thus decrease accidents is always a welcome area of study.

New laser technology could help clear up icy roads in the winter

There’s no denying global <a href="https://www.earth.com/news/humans-driving-climate-change/">climate change</a>... unless of course you specifically try and ignore facts. A new study has found that popular climate change denying websites and blogs do just that, by relying only on other blogs and websites instead of taking facts from scientific studies. 

Unfortunately, no matter how contestable the less than reputable stories are, there are many people who take information as fact, regardless of the source. 

On one side you have science-driven arguments, proving that an increase in greenhouse gas emissions caused by human-driven activities is warming our planet. On the other side, you have climate change deniers, who call the whole thing a hoax.

Researchers from the <a href="https://nioo.knaw.nl/en">Netherlands Institute of Ecology</a> examined climate blogs and found that even though climate deniers had almost no basis in fact, they had a much stronger social media influence than science-based blogs. 

“We found a major gap between the facts from scientific literature and the science-based blogs on the one hand, and the opinions aired in climate-change denying blogs on the other,” said Jeff Harvey, the first author of the study. “It's a very dangerous gap, as these blogs are read by millions.” 

According to the study authors, polar bears are the “poster species” of anthropogenic global warming. Polar bears, melting sea ice, weather extremes, these are all used as evidence of the impacts of global climate change. 

However, blogs devoted to climate change denial often downplay or disregard how climate change is negatively affecting polar bears and cast doubt on climate change arguments.  

For the study, the researcher read through 90 climate blogs and 92 scientific papers. Of those, 45 denier blogs didn’t include peer-reviewed evidence in the scientific papers and instead took their information from other climate denying blogs. 

80 percent of the climate-denying blogs got their facts from one blog that had no original research. 

45 of the science-based blogs did match up with the scientific papers, but there was a major gap between the blogs based in scientific fact and the ones just borrowing information from other similar blogs and websites. 

The researchers say this study is an opportunity to show how science-based blogs and climate change scientists can combat deniers by engaging more with the public on social media platforms. 

“Scientists, climb down from your desk and start to counter the misinformation on social media directly - and via the traditional media as well,” said Harvey. “Engage with the public via the blogosphere or citizen science for example. And very importantly, adjust your focus to what is clear instead of all the uncertain things still to be studied.”

Fact vs opinion: Battling climate change misinformation online

There’s no denying global climate change... unless of course you...

Sitting in on the hard plywood floor of the cramped wildlife hide, we peeked out of the windows on a flat piece of grassland, eerily lit by a nearly full moon.  The early morning hours seemed full of potential as Erin, my girlfriend, and I sat whispering and sipping coffee from a dented green thermos.  In those hours before the grouse arrived I thought back to another lek.

Erin and I worked for three months as temporary managers of a nature reserve in the cloud forest near Mindo, Ecuador.  Besides maintaining facilities and assisting guests, a large part of our work was bird work.  On our first full day being oriented to our responsibilities, we rose before dark and were led by the departing reserve managers on a path climbing a hill through dense, tropical forest.  The trail led to a small spur trail that ended at a small shack draped in camouflage netting.  Inside the small tin roofed blind, we sat on a rough wooden bench and waited with clipboards of empty data sheets and binoculars hung ‘round our necks.  Eventually we heard the flutter of arriving wings and the loud, rising aaaawoooo cry of the male Andean Cock of the Rock (Rupicola Peruvianus) abbreviated: ACOR.  

Through the dense foliage there wasn’t as much to see of the birds as one could hope. The exotic vocalizations and loud beating of wings as males sparred or showed off gave the imagination a lot of material.  The Andean cock of the rock is a medium sized bird that is rather non-descript except for the bright red and large crest on the males heads.  In the early morning dimness, through the tangle of branches, vines and epiphytic bromeliads the ACOR males were mostly flashes of vivid color against a collage of green.  

Watching the Sharp Tailed Grouse (Tympanuchus phasianellus jamesi) was the opposite of the half-veiled display of the ACOR.  With the grouse, everything was on display.  The name, Sharp Tailed Grouse, proved to be very adept at capturing the bird.  The males in displaying point their tails straight up, revealing a white rump pointing sharply indeed at the sky.  The birds make a rattling noise as they shake back and forth, snaking in lines through the lek.  Then all the grouse freeze.  It seems the males pause in their dance to see if any females have taken notice.  One time all the males froze except one who kept dancing for a bit, oblivious, when he saw his mistake I imagine he stopped quickly to hide his embarrassment.  A few of the males seemed more dominant or at least made a more impressive lekking display; these inflated bright purple pouches in their neck.  There were also the plump, clucky squelching noises and the excitable birds jumping into the air.  

From the site of the grouse lek, you could look across the rolling fields of grassland cut by the regular lines of barb wire to the water tower of the town of Wall.  At night, when we heard coyotes yipping their savage song we could see the tiny lights of Wall twinkling, like a far off dream.  

In Ecuador as with the grouse, the lekking happened in the early morning but less impressively before sunset.  For a small fee we would take guests to the blind to watch the ACOR.  One afternoon I took a young Italian man who said he was also a biology student to watch the ACOR lek.  As we were sitting in the hide waiting patiently for the birds’ tell-tale aaaawoooo or the sharp rattle of wings, I heard the far off beep beep beep of a car alarm.  We sat quietly and waited for the birds to come, they came but over the time we were in Ecuador, we noticed them coming less often.    

As we sat in the blind watching the grouse, the dance became a little less active but the birds were still all around us.  The sun was just starting to come up.  Erin and I sat tight, the forest service information packet which told us how to get here warned us to leave the grouse undisturbed until they were all gone.  For grouse, lekking grounds are special places, places they return to year after year.  I heard a story of people inadvertently building a house on top of a lekking place.  The birds were said to return and lek on the roof of the house.  The truth is that human disturbance has a huge impact on grouse.  You won’t see a lek in the parking lot of a shopping mall.  My bird book tells me that the Sharp-tailed Grouse were once much more widespread than today.  A range that spread along much of Canada and the western US has been shattered and shrunk to islands dotting the map.  Sharp Tailed Grouse are considered a species of Least Concern; they have a stable population; does that mean we shouldn’t mourn what is lost?  

As Erin and I sat, patiently waiting for the grouse to leave on their own, men in the blind next to ours stepped outside, hefting a camouflage camera with a huge lens.  The birds were a flap of feathers and then gone.  The men walked to their car without a second thought.  We sat, filled with rage and waited, maybe the birds would return.  We waited in vain, the grouse were gone.

<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."
