Hotter summers are not just uncomfortable, they also changing the odds of getting sick from food. A new analysis links warmer air, higher moisture, specific dewpoint ranges, and longer daylight to spikes in Salmonella infections across two European countries. 



The team showed that risk climbs when average temperatures rise above about 50°F and days stretch past 12 to 15 hours.



Lead author <a href="https://www.londonntd.org/research/researchers/laura-c-gonzalez-villeta" target="_blank" rel="noreferrer noopener">Dr. Laura C. González Villeta</a> of the University of Surrey’s <a href="https://www.surrey.ac.uk/school-veterinary-medicine" target="_blank" rel="noreferrer noopener">School of Veterinary Medicine</a> led work that tied laboratory confirmed Salmonella cases to local weather conditions using a transparent statistical approach.



The bacteria called Salmonella cause <a href="https://my.clevelandclinic.org/health/diseases/15697-salmonella" target="_blank" rel="noreferrer noopener">food poisoning</a> that often brings diarrhea, fever, and stomach cramps. Common symptoms usually start within hours to a few days and most people recover without treatment.



<h2 class="wp-block-heading" id="h-salmonella-and-the-weather">Salmonella and the weather</h2>



Researchers linked daily case counts from the <a href="https://www.gov.uk/government/organisations/uk-health-security-agency" target="_blank" rel="noreferrer noopener">UK Health Security Agency</a> to detailed weather from the <a href="https://www.metoffice.gov.uk/" target="_blank" rel="noreferrer noopener">Met Office</a>, then checked the model with national surveillance data from the Netherlands. 



They examined 14 factors, including temperature, relative humidity, precipitation, sunshine, and dewpoint temperature.



Instead of forcing a complex equation to fit the data, the group calculated a conditional incidence that directly describes how often cases occur when specific combinations of weather are present. 



That method lets you see which trio of conditions lines up with higher infection counts without hiding the signal inside a black box.



The approach showed consistency when moved from one country to another after accounting for reporting differences. That matters because public <a href="https://www.earth.com/news/to-get-fit-and-stay-healthy-walk-this-exact-distance-every-day/">health</a> tools work best when they travel across borders without losing accuracy.



<h2 class="wp-block-heading" id="h-what-the-model-found">What the model found</h2>



Risk rose when average air temperatures topped roughly 50°F, day length sat between 12 and 15 hours, and dewpoint hovered around the mid 40s to about 50°F. The same pattern appeared regardless of location.



Not every weather knob seemed important. Wind speed, air pressure, and sunshine duration had little or no association with reported cases in this dataset.



Seasonal peaks in late summer were reproduced when the model fed on local weather. That gave officials a way to anticipate risk based on last week’s skies rather than waiting for lab reports to trickle in.



<h2 class="wp-block-heading" id="h-how-weather-boosts-salmonella">How weather boosts Salmonella</h2>



Broader evidence lines up with these findings. A large <a href="https://pmc.ncbi.nlm.nih.gov/articles/PMC11530612/" target="_blank" rel="noreferrer noopener">meta-analysis</a> of 23 Salmonella studies found about a 5 percent rise in risk for every 1.8°F increase in temperature.



Europe’s outbreak history shows why this topic matters. In 2018, nearly one in three foodborne outbreaks in the European Union were caused by Salmonella, according to an EFSA <a href="https://www.efsa.europa.eu/en/news/salmonella-most-common-cause-foodborne-outbreaks-european-union" target="_blank" rel="noreferrer noopener">report</a>.



That baseline risk has not disappeared in recent years. Surveillance summaries still identify Salmonella as a leading cause of foodborne outbreaks across the region, with eggs and mixed foods often involved, as noted in EFSA’s public <a href="https://www.efsa.europa.eu/en/efsajournal/pub/7666" target="_blank" rel="noreferrer noopener">publication</a>.



<h2 class="wp-block-heading" id="h-what-this-means-for-public-health">What this means for public health</h2>



“The study highlights how weather plays a significant role in <a href="https://www.earth.com/news/dogs-are-overlooked-sources-of-antibiotic-resistant-salmonella/">Salmonella</a> outbreaks and provides a valuable tool for predicting future risks and tailoring interventions, particularly in the context of climate change,” said Dr. Villeta. The work is not just about describing patterns.&nbsp;



Weather aware forecasting can help agencies time inspections, target hygiene messaging, and plan surge capacity when the odds of illness tick up. 



Food businesses can also adjust cold chain checks, staff training, and consumer advice when riskier conditions line up.



Individuals are not powerless either. Keep cold foods cold, cook poultry and eggs to safe temperatures, refrigerate leftovers within 2 hours, and wash hands and surfaces, especially when the air is warm and the day runs long.



<h2 class="wp-block-heading" id="h-high-tech-forecasting-tools">High-tech forecasting tools</h2>



Most forecasting tools lean on regression or time series fits that struggle with tangled, non linear interactions. 



The conditional incidence approach shows how combinations of temperature, humidity, and daylight align with cases, which is easier to interpret and to explain.



That clarity helps separate what drives risk from noise. It also allows public health teams to identify factor combinations that do not explain much, saving effort where it will not pay off.



Model outputs replicated real world peaks and mapped risk at fine spatial scales. That is the level where <a href="https://www.earth.com/news/childrens-screen-time-shapes-their-mental-health-as-teens/">health</a> departments and food producers make day to day choices.



<h2 class="wp-block-heading" id="h-limits-and-next-steps">Limits and next steps</h2>



The model tracks reported cases, which understate total infections. Even so, de trending and validation across two countries suggest the weather signals are real.



Future tests in different climates and income settings would show how far the method travels. Adding data on livestock density, land use, and consumer behavior could sharpen predictions without losing transparency.



Better early warnings do not replace basic food safety, but they can make those steps more timely. That is useful as warmer summers and longer heat seasons become more common.

Warmer weather is impacting global food supply, but not in the way you think

Hotter summers are not just uncomfortable, they also changing the odds of getting sick from food.

Deforestation, palm oil plantations, and <a href="https://www.earth.com/news/legume-trees-play-a-key-role-in-forest-recovery/">forest</a> conversion have been linked to an increasing number of infectious disease outbreaks. 

The research, published by <a href="https://www.frontiersin.org/">Frontiers</a>, is the first of its kind to analyze how changes in forest cover may contribute to diseases carried by mosquitoes, ticks, and other vectors, as well as to infections that can jump from animals to humans like COVID-19.

Study lead author Dr. Serge Morand is a scientist at CNRS, the French Agricultural Research Centre for International Development (CIRAD), and at Kasetsart University in Thailand.

"We don't yet know the precise ecological mechanisms at play, but we hypothesize that plantations, such as oil palm, develop at the expense of natural wooded areas, and reforestation is mainly monospecific forest made at the expense of grasslands," said Dr. Morand. "Both land use changes are characterized by loss of biodiversity and these simplified habitats favor animal reservoirs and vectors of diseases."

Deforestation is damaging to biodiversity and human health, and accelerates climate change. In Brazil, deforestation has already been linked to outbreaks of malaria, yet the global impacts of forest cover changes on human health have not been well-studied.

To investigate, the researchers analyzed changes in forest cover around the world between 1990 and 2016. They looked at deforestation, but also reforestation and afforestation, which includes the conversion of natural grasslands and the abandonment of agricultural land. 

The experts compared their results to the local population densities and outbreaks of vector-borne and zoonotic diseases. 

The study confirmed that both deforestation and afforestation were significantly correlated with disease outbreaks. There was a strong association between deforestation and epidemics like malaria and Ebola in Brazil, Peru, Bolivia, the Democratic Republic of Congo, and other tropical countries.

By contrast, temperate regions like the United States, China, and Europe showed clear links between afforestation and vector-borne diseases like Lyme disease.

In particular, the experts found a significant increase in disease outbreaks in countries with expanding palm oil plantations. The effects were even more pronounced in countries like China and Thailand that are susceptible to mosquito-borne diseases such as dengue, zika, and yellow fever.

"We hope that these results will help policymakers recognize that forests contribute to a healthy planet and people, and that governing bodies need to avoid afforestation and agricultural conversion of grasslands," said Dr. Morand. 

"We'd also like to encourage research into how healthy forests regulate diseases, which may help better manage forested and planted areas by considering their multidimensional values for local communities, conservation and mitigation of climate change."

The study is published in the journal <a href="https://www.frontiersin.org/journals/veterinary-science">Frontiers in Veterinary Science</a>.

As increasing levels of atmospheric carbon dioxide accelerate plant growth, the soil may not be able to keep up with the pace. Researchers at <a href="https://www.stanford.edu/">Stanford University</a> found that when elevated <a href="https://www.earth.com/news/active-travel-can-greatly-reduce-co2-emissions-in-the-city/">CO2</a> levels give plants a boost, the soil begins to lose its ability to store more carbon. 

One likely explanation is that plants effectively mine the soil for nutrients they need to keep up with carbon-fueled growth, according to the study authors. The extra nutrients are made available to plants through increased microbial activity in the soil, which releases CO2 that would otherwise remain locked away.

Scientists have widely accepted the idea that plant biomass and soil carbon will increase simultaneously. However, the researchers found that this is not the case. 

"When plants increase biomass, usually there's a decrease in soil carbon storage," said lead author César Terrer.

The team analyzed data from 108 previously published studies on high CO2 concentrations, soil carbon levels, and plant growth. The results showed that soils only accumulated more carbon in experiments where plant growth remained fairly steady. 

"It proved much harder than expected to increase both plant growth and soil carbon," said senior study author Professor Rob Jackson. He explained that climate projections do not account for this tradeoff, which means they likely overestimate the potential of the terrestrial carbon sink. 

Each year, plants and soils collectively absorb an estimated 30 percent of the CO2 emissions associated with human activities. It is particularly important to understand how the underground part of the terrestrial carbon sink will change in the coming decades, considering that carbon absorbed by the soil tends to remain stored for a very long time. 

"When a plant dies, some of the carbon that accumulated in its biomass may return to the atmosphere. In soils, carbon can be stored for centuries or millennia," said Terrer.

In 2019, the Stanford team determined that as CO2 levels continue to rise, plants will likely play a far less significant role in drawing down carbon than previously predicted. The new research indicates that the soil will also fall short as a carbon sink as plant biomass increases. 

"Soils store more carbon worldwide than is contained in all plant biomass," said Professor Jackson. "They need much more attention as we project the fate of forests and grasslands to the changing atmosphere."

The study is published in the journal <a href="https://www.nature.com/">Nature</a>.

Along much of the U.S. Atlantic <a href="https://www.earth.com/news/the-sea-is-rising-up-to-four-times-faster-in-coastal-communities/">coast</a>, the rate of sea-level rise in the 20th century was the highest it has been in the last 2,000 years, according to a new study from <a href="https://www.rutgers.edu/">Rutgers University</a>. The fastest rate of sea-level rise was found in southern New Jersey.

Rising ocean temperatures and melting ice cover caused a global rise in sea levels from 1900 to 2000 that more than doubled the average for the years 0 to 1800.

The experts analyzed the factors that contributed to ocean level changes over 2,000 years at six sites along the East Coast based on a sea-level budget. 

The researchers explained that sea-level budget assessments quantify the different physical processes contributing to sea-level change. These processes include global fluctuations in ice cover, regional changes such as land subsidence, and local factors such as groundwater withdrawal.

Study lead author Jennifer S. Walker is a postdoctoral associate in the Department of Earth and Planetary Sciences in the School of Arts and Sciences at Rutgers University-New Brunswick. 

"Having a thorough understanding of sea-level change at sites over the long-term is imperative for regional and local planning and responding to future sea-level rise," said Walker. "By learning how different processes vary over time and contribute to sea-level change, we can more accurately estimate future contributions at specific sites."

Sea-level rise linked to climate change threatens to permanently inundate low-lying islands and coastal areas. Rising sea levels also make these regions more vulnerable to flooding and damage from storms.

The goal of the Rutgers study was to better understand how the processes that affect sea levels have changed and how they could shape future changes. The sea-level budget method used for the analysis could be applied to other sites around the world.

The researchers used a statistical model to develop sea-level budgets for six sites, dividing sea-level records into global, regional and local components. The experts determined that regional land subsidence, or sinking land, has dominated the budget of each site over the last 2,000 years. 

Regional and local processes, such as groundwater withdrawal, were found to contribute much less to each budget and vary over time.

The total rate of sea-level rise for each of the six sites in the 20th century ranged from 2.6 to 3.6 millimeters per year - the fastest changes in the sea level in 2,000 years. Southern New Jersey had the fastest rates, with over 1.6 millimeters a year measured at Edwin Forsythe National Wildlife Refuge in Atlantic County and 1.5 millimeters a year at Cape May Court House.

The study is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.

In a new study from <a href="https://www.cell.com/">Cell Press</a>, experts have found remarkable butterfly diversity in the <a href="https://www.earth.com/news/burrowing-animals-in-the-mojave-desert-escape-the-heat-of-climate-change/">deserts</a> of Mexico and the southwestern United States. The surprising discovery may be tied to actively changing conditions in the in the western portion of North America.

"When you think of desert, you don't automatically jump to butterflies, but our results showed that this area is actually a really important hotspot for butterflies, even if it isn't for plants," said study co-first author Chandra Earl. "Just because butterflies are closely tied to their host plants doesn't mean their diversity outcomes have to be similar."

The researchers conducted a continent-wide analysis using a variety of biodiversity databases, including GenBank, Barcode of Life Data System (BOLD), and Map of Life (@moldotorg). 

The experts did not simply count the number of butterfly and plant species in a given area, but also examined the degree of evolutionary relatedness - or phylodiversity - of species in each region. 

"We wouldn't have found the same result if we'd just counted the species like most biodiversity studies." said Earl. "But we really wanted to step away from that, so we didn't lose the importance of evolutionary history."

The researchers explained that butterfly diversity may be greater than that of plants in the desert due to how they interact in the ecosystem.

"Most butterflies are generalists that don't utilize just one host plant. This means that there are a lot of plants with no real functional relevance to butterflies" said study co-first author Michael Belitz. "This makes butterflies less likely to clump into groups of tightly related species like plants do."

There are other ecological factors that may also play a role in butterfly diversity across North American deserts, including the fact that butterflies are much more mobile than plants. 

"These factors all add noise to the data, where you won't see as strong a relationship between plants and butterflies as you might expect," explained Belitz.

The researchers hope that this new understanding of butterfly diversity will encourage others to research and help conserve the insects.

"People already know about the decline of monarch butterflies, but the entire group is under threat," said Earl. "We need to start paying better attention to insects, and this study helps prioritize North American deserts as a new target for conservation efforts."

The study is published in the journal <a href="https://www.cell.com/iscience/home">iScience</a>.

Surprisingly high butterfly diversity found in North American deserts

In a new study from Cell Press, experts have found...

A new study shows that certain plant characteristics such as generation time can predict how sensitive species are to climate change. An international team of researchers led by the <a href="https://www.idiv.de/en/index.html">German Centre for Integrative Biodiversity Research</a> (iDiv) set out to investigate how plant populations have responded to climate change over time. 

To address this question, the experts collected all of the relevant data available worldwide, which was mostly from Europe and North America. The investigation revealed that plant species with short generation times are more sensitive to climate change than species with long generation times. 

According to the researchers, their work has important implications for predicting which plant species need the most protection and conservation attention.

Climate change is one of the biggest threats to plant diversity. In order to protect biodiversity, it is critical for experts to understand which species are the most urgently threatened and where. 

The iDiv team compiled all long-term studies on plants that measured population growth rates. The experts assessed how climate factors, particularly precipitation and temperature, influenced the growth rate during each study period. 

The researchers then analyzed how specific features of a plant species, such as the length of a generation, influenced its growth responses to climate variation in the past.

"We were able to show that generation duration is a useful indicator value for a species' susceptibility to climate change," said study first author Dr. Aldo Compagnoni. 

For example, the experts found that plants with short lifespans, including those that only live a few years, suffered much more from climate extremes than long-lived species. 

The researchers also clarified that rising temperatures were not the main climate-related factor that limited plant growth. On average, precipitation had a three times greater impact on plant populations than temperature.

"This work helps us identify which species might be climate-vulnerable, even if we have limited information about those species," said study co-author Professor Tiffany Knight. 

"For example, while we have long-term population data for a small subset of plant species on Earth, we can estimate the approximate generation duration for most plant species. This is an important first step towards determining species' vulnerability to climate change at a global scale."

At the same time, however, the experts noted that there are important data gaps that limit the ability to make general predictions on a global scale. The researchers found suitable long-term datasets only for 62 of the 350,000 plant species on Earth, and the vast majority of these were species occurring in temperate zones.

The study authors conclude that to be able to make reliable predictions about the consequences of climate change for all regions of the world and all known species, new population ecology research is needed on woody plant species and plants in the tropics.

The study is published in the journal <a href="https://www.nature.com/ncomms/">Nature Communications</a>.

In a new study led by the <a href="http://www.leeds.ac.uk/">University of Leeds</a>, researchers have discovered that rocks on the seafloor provide essential nutrients to marine organisms at the base of the food chain. The experts report that iron, an essential nutrient phytoplankton, is being released from sediments on the deep seafloor.

The findings contradict the idea that oxygen in the deep-sea prevents dissolved iron from escaping the seafloor. Instead, it turns out that the combination of oxygen and organic matter may promote the release of iron from sediments.

"Our findings reveal that the shallow surface of the deep seafloor provides an important source of iron - a scarce micronutrient - for the ocean," said study lead author Dr. Will Homoky of Leeds' School of Earth and Environment.

"We show that the degradation of rock minerals with organic matter and oxygen is a recipe to produce tiny rust particles, which are small enough to be dissolved and carried in seawater." 

"These tiny rust particles and their chemical signatures explain how iron found in large parts of the ocean interior could have come from deep ocean sediments, in a manner which was once thought to be practically impossible."

The ultramicroscopic iron particles, known as colloids, may provide an important source of nutrition for phytoplankton, which serve as the base of the marine food chain. Phytoplankton also help to mitigate climate change by absorbing an enormous amount of carbon dioxide from the atmosphere. 

"Our findings here are significant, because they mark a turning point in the way we view iron supply from sediments and its potential to reach marine life that paves a new way of thinking about the seafloor," said Dr. Homoky.

"Our discovered production of iron colloids is different to other forms of iron supplied to the ocean, and will help us design a new generation of ocean models to re-evaluate marine life and climate connections to the seafloor - where large uncertainty currently exists.

"This could help us to better understand how iron in the ocean has contributed to past productivity and climatic variations and inform our approaches to marine conservation and management."

The researchers analyzed tiny variations within the fluid content of sediment samples collected from the South Atlantic Ocean at water depths up to 60 meters.

Study co-author Dr. Tim Conway is an assistant professor at the University of South Florida. He explained that the ability to analyze important variations in the chemical makeup of seawater were beyond our reach a decade ago.

"Here we have characterized an isotope signature belonging to the iron colloids produced in deep ocean sediments that we can use to trace their journey in the ocean," said Dr. Conway.

"Our continuing goal is to learn how far this iron travels and how much of it nourishes our marine food webs around the globe."

The study is published in the journal <a href="https://www.springer.com/journal/40011">Proceedings of the National Academy of Sciences</a>.

In a new study from <a href="https://www.colostate.edu/">Colorado State University</a> and the National Park Service, experts report that natural <a href="https://www.earth.com/news/changing-ocean-soundscapes-impact-animals-worldwide/">sounds</a> are associated with striking health benefits. The researchers found that when people are exposed to the sounds of nature in national parks, they experience decreased pain, lower stress, improved mood, and enhanced cognitive performance. 

The sound of water was found to be most effective at improving positive emotions and health outcomes, while the sounds of birds helped to combat stress and annoyance.

As part of the study, the team scrutinized sound recordings from 251 sites in 66 national parks across the United States. Dozens of CSU students identified different types of sounds in the recordings.

"In so many ways the COVID-19 pandemic has emphasized the importance of nature for human health" said study lead author Rachel Buxton. "As traffic has declined during quarantine, many people have connected with soundscapes in a whole new way - noticing the relaxing sounds of birds singing just outside their window. How remarkable that these sounds are also good for our health."

Professor Amber Pearson said the findings highlight that natural sounds may actually bolster mental health, in contrast to the harmful health effects of noise.

"Most of the existing evidence we found is from lab or hospital settings," said Professor Pearson. "There is a clear need for more research on natural sounds in our everyday lives and how these soundscapes affect health."

National parks have some of the most pristine soundscapes in the United States, and the National Park Service increasingly recognizes natural sounds in policy. 

The research team found that while there are some sites with abundant natural sounds, national parks that are frequently visited are more likely to be inundated with noise. This means that many park visitors are not reaping the health benefits associated with more quiet spaces.

Study co-author Kurt Fristrup is a bioacoustical scientist at the National Park Service. 

"Park sites near urban areas with higher levels of visitation represent important targets for soundscape conservation to bolster health for visitors," said Fristrup.

"Nature-based health interventions are increasingly common in parks and incorporating explicit consideration of the acoustic environment is an opportunity to enhance health outcomes for people."

The study is published in the journal <a href="https://www.pnas.org/">Proceedings of the National Academy of Sciences</a>.

Microplastics have been detected in fresh falling snow in an urban setting, according to a new study from <a href="https://www.mcgill.ca/">McGill University</a>. Even after the snow had melted, traces of micro- and nano-plastics were left behind.

The researchers found that these particles are primarily sourced from plastics found in antifreeze products, or polyethylene glycols, that can become airborne and picked up by the snow.

The researchers developed a method for analyzing snow, water, and soil samples to search for traces of microplastics. The experts report that their new technique is orders of magnitude more sensitive than any of the other current methods used for tracing plastic in the environment.

"We herein develop in-laboratory built nanostructures (zinc oxide, titanium oxide and cobalt) coupled to mass spectrometry techniques, for picogram quantification of micro/nanoplastics in water and snow matrices, without sample pre-treatment," wrote the researchers.

The scientists are now able to detect ultra-trace quantities of many of the most common soluble and insoluble plastics down to the level of a picogram, or one trillionth of a gram. 

"It is important to be able to detect even trace quantities of plastics in the environment," said study senior author Parisa Ariya.

"Though these plastics may be harmless in themselves, they can pick up toxic organic matter and heavy metals from the environment, which can damage human cells and organs."

The new technique is both recyclable and based on sustainable practices.

"Our hope is that this new technique can be used by scientists in different domains gain key information about the quantity of micro- and nano-plastics in urban environments in order to better address their impacts on the ecosystem and on human health," concluded study first author Zi Wang.

The research is published in the journal <a href="https://www.journals.elsevier.com/environmental-pollution">Environmental Pollution</a>.

Melting glaciers in Alaska contributes to earthquakes, according to a new study. The researchers determined that <a href="https://www.earth.com/video/greenland-ice-is-more-sensitive-to-climate-change-than-expected/">ice</a> loss in the 19th century laid the groundwork for a devastating earthquake in Lituya Bay in 1958.

The 7.8 magnitude earthquake triggered a rockslide and created a tsunami that ran 1,700 feet up a mountainside before plummeting back out into the sea.

According to scientists at the <a href="https://www.uaf.edu/">University of Alaska Fairbanks</a>, ice loss near Glacier Bay National Park has influenced the timing and location of nearby earthquakes with a magnitude of 5.0 or greater during the past century.

While it was already known that melting glaciers cause earthquakes in otherwise tectonically stable regions, such as Canada's interior and Scandinavia, this pattern has been harder to detect in Alaska.

Some of the world's largest glaciers can be found in Alaska. These glaciers can be up to thousands of feet thick and cover hundreds of square miles. 

The weight of the ice causes the land beneath it to sink, and the ground springs back like a sponge when the ice melts. The disappearance of glaciers has caused Southeast Alaska's land to rise at about 1.5 inches per year.

"There are two components to the uplift," said study lead author Chris Rollins. "There's what's called the 'elastic effect,' which is when the earth instantly springs back up after an ice mass is removed. Then there's the prolonged effect from the mantle flowing back upwards under the vacated space."

The research links the expanding movement of the mantle with large earthquakes across Southeast Alaska, where glaciers have been melting for over 200 years. 

Based on models of Earth movement and ice loss since 1770, the researchers identified a clear correlation between earthquakes and Earth rebound. 

Maps of ice loss and seismic records dating back to 1920 showed that most large earthquakes coincided with the stress from long-term Earth rebound.

In the case of the 1958 earthquake, the postglacial rebound molded the crust around the fault in a way that increased stress near the epicenter.

"The movement of plates is the main driver of seismicity, uplift and deformation in the area," said Rollins. "But postglacial rebound adds to it, sort of like the de-icing on the cake. It makes it more likely for faults that are in the red zone to hit their stress limit and slip in an earthquake."

The study is published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/journal/21699356">JGR Solid Earth</a>.

A new report from the <a href="https://www.agu.org/">American Geophysical Union</a> reveals that Jupiter's Great Red Spot, a massive storm that is about twice as wide as Earth, is being fed by smaller storms.

Over the past few years, a series of anticyclones crashed into the Great Red Spot and caused chunks of red clouds to flake off, which shrunk the larger storm. The new study shows that these disruptions are just superficial, and do not affect the full depth of the Red Spot.

Study lead author Agustín Sánchez-Lavega is a professor of applied physics at the Basque Country University in Bilbao. He explained that as the larger storm absorbs these smaller storms, it "gains energy at the expense of their rotation energy."

"The intense vorticity of the Great Red Spot, together with its larger size and depth compared to the interacting vortices, guarantees its long lifetime," said Professor Sánchez-Lavega.

Prior to 2019, the giant storm only encountered a couple of anticyclones per year. In the last couple years, however, the Red Spot has been hit by as many as two dozen smaller storms in a year. 

The researchers set out to investigate whether the anticyclones had disturbed the spin of the giant storm. The Great Red Spot spins in the atmosphere near the planet's equator, with wind speeds of up to 335 miles per hour along its border.

Anticyclones spin in the opposite direction of cyclones around a center with high atmospheric pressure. The Great Red Spot is an anticyclone that is six to seven times as big as the smaller anticyclones that have been colliding with it. The "smaller" storms on Jupiter are still about 10 times the size of the largest terrestrial hurricanes.

Professor Sánchez-Lavega and his team looked at satellite images of the Great Red Spot for the past three years taken from the Hubble Space Telescope and the Juno spacecraft, as well as photos taken by a network of amateur astronomers with telescopes.

The researchers found that the smaller anticyclones pass through the high-speed peripheral ring of the Great Red Spot before circling around the red oval. 

According to Professor Sánchez-Lavega, the invading storms create some chaos in an already dynamic situation, temporarily changing the Red Spot's 90-day oscillation in longitude, and "tearing the red clouds from the main oval and forming streamers."

Experts are not sure how the Red Spot initially formed or what has been causing it to shrink for at least 150 years, but the current study suggests that smaller storms are helping to maintain it. 

"The ingestion of anticyclones is not necessarily destructive; it can increase the GRS rotation speed, and perhaps over a longer period, maintain it in a steady state," said Professor Sánchez-Lavega.

The study is published in the <a href="https://agupubs.onlinelibrary.wiley.com/journal/21699100">Journal of Geophysical Research: Planets</a>.

In a new study published by <a href="https://www.wiley.com/en-us">Wiley</a>, experts have found that artificial light at night interferes with the courtship and mating of bioluminescent <a href="https://www.earth.com/news/tourists-who-are-flocking-to-see-fireflies-may-be-causing-them-harm/">fireflies</a>.

"Over the past century, widespread adoption of increasingly inexpensive and intense lighting technologies has significantly brightened urban and suburban environments, road networks, biodiversity hotspots, and even protected areas," wrote the researchers

"Artificial light at night (ALAN) significantly impacts the fitness of diverse nocturnal, crepuscular, and diurnal taxa - primarily by disrupting their orientation in space and time and by making it difficult for them to visually recognize predators, prey, or conspecifics."

According to the experts, bioluminescent insects that communicate through glowing lures, warning signals, or courtship displays may have their signals obscured by artificial illumination.

"Previous research has demonstrated that broad spectrum white light inhibits the production of courtship advertisements by male firefly beetles, yet the impact of varying wavelengths of artificial light on both members of the courtship dialogue is largely unknown," wrote the study authors. 

"We exposed courting pairs of Photinus obscurellus fireflies to five colors of downwelling illumination, at two intensities, and recorded changes in male flash rate and flash intensity, female responsiveness, and the flash pattern composition of both sexes."

The investigation revealed that all of the artificial light treatments significantly suppressed courtship activity, but bright amber light had the greatest impact. This indicates that artificial lights with colors similar to firefly bioluminescence may be the most disruptive to firefly courtship.

"It's definitely concerning, because many ecologically-minded people are pushing the use of amber lights to safely light up streets and parks. But we're finding that no color of light is safe for fireflies, they need the dark," said study co-author Avalon C.S. Owens.

The research is published in the journal <a href="https://onlinelibrary.wiley.com/journal/17524598">Insect Conservation and Diversity</a>.

In the first study of its kind, an international team of scientists led by the <a href="http://www.reading.ac.uk/">University of Reading </a> has investigated insect pollinator stability over multiple years and sites worldwide. The experts found that crop pollination services are more stable in fields and farms with a greater variety of insect pollinators. 

The investigation showed that diverse communities of insect pollinators, and areas with stable populations of dominant species, can reduce year-to-year fluctuations in crop pollination.

The results suggest that supporting pollinator diversity could provide long-term benefits to food production.

"Most previous research into pollinator stability has focused on space, not time. However, year-to-year variations in pollination services cause boom and bust cycles in crop harvests, which can have a damaging impact on agriculture and livelihoods globally," explained study lead author Dr. Deepa Senapathi.

"Stable and consistent pollination services are therefore important in underpinning businesses and livelihoods, as well as providing a reliable supply of food for retailers and consumers."

"This study has revealed that the secret to consistent crop harvests could be to encourage pollinator diversity on or near farmland. If we want pollinators to help us, first we need to help them, through land management decisions that preserve and increase the number of insect pollinator species."

Insect pollinators support reproduction in at least 78 percent of wild plants, while contributing to the pollination of 75 percent of major crops. At the same time, wild insect pollinator populations are declining in areas of northwest Europe and North America, where crop production is widespread. 

It is becoming increasingly important to understand how plant pollinator populations change over time, as well as the associated impacts with their fluctuations.

For the current study, the researchers collected wild pollinator data from hundreds of field sites in 12 different countries across six continents over multiple years. The team studied populations of pollinating insects - including bees, hoverflies, butterflies, and beetles - in the vicinity of 21 different crop species.

The research confirmed that high pollinator diversity increases crop production. In intensive farming systems where there may be a reduced diversity of pollinators, the experts found that protecting the dominant species was also effective in providing long-term stability in pollination.

Further research is needed to determine which types of land management techniques are most effective for boosting insect diversity.

The study is published in the journal <a href="https://royalsocietypublishing.org/journal/rspb">Proceedings of the Royal Society B</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.

<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.

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.

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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