Imagine Earth has a giant set of underground “storage lockers” where we can tuck away carbon dioxide (CO₂) for centuries so it doesn’t heat the planet. Scientists call this geologic carbon storage. 



It sounds simple: capture CO₂ from factories, power plants, or even the air, pipe it deep underground into the tiny spaces inside certain rocks, and lock it there.



For years, underground storage of carbon dioxide looked and felt like a clever climate trick. Capture the gas, lock it in rock layers, and keep burning fossil fuels while claiming progress. 



The idea seemed safe because early estimates suggested nearly limitless space.



That illusion has collapsed. New research shows the planet’s usable underground storage capacity is far smaller than imagined. Instead of centuries of security, this cushion could run out within 200 years.



<h2 class="wp-block-heading" id="h-carbon-storage-drops-sharply">Carbon storage drops sharply</h2>



Industry once placed global capacity at around 14,000 gigatons. A closer look, however, strips away risky regions - earthquake zones, fragile <a href="https://www.earth.com/news/construction-materials-could-store-carbon-in-homes-and-buildings-helping-the-climate/">ecosystems</a>, and crowded cities. What remains is only about 1,460 gigatonnes.



This tenfold drop changes everything. What once seemed endless is now a resource with strict boundaries, one that must be managed carefully. Every choice about how it is used carries long-term consequences. 



If reserved for short-term fixes, the world risks burning through it quickly. If protected for carbon removal, it could become a critical lifeline for stabilizing temperatures far into the future.



<h2 class="wp-block-heading" id="h-risks-hidden-beneath-the-surface">Risks hidden beneath the surface</h2>



Underground storage carries hazards. Injecting carbon can stir up seismic activity, reactivate faults, or open escape paths. Leaks into aquifers could acidify water and release toxic metals. 



Offshore storage avoids some human risks but adds cost and geopolitical disputes. Public pushback also limits expansion, with some governments blocking projects altogether.



Opposition often stems from fears of leaks, distrust of industry promises, and concerns that <a href="https://www.earth.com/news/carbon-storage-mystery-emerges-in-the-southern-ocean/">storage</a> will be used to justify continued fossil fuel use. 



These challenges mean underground storage cannot expand smoothly or universally; every project faces technical, political, and social barriers that slow progress and shrink real-world potential.



<h2 class="wp-block-heading" id="h-carbon-storage-s-uncertain-future">Carbon storage’s uncertain future</h2>



Climate plans already assume storage will be vital to reach net zero. But if it mainly serves fossil fuel plants, reserves could vanish by 2200 - and every decade of delay accelerates that timeline. 



Deep emission cuts now ease future pressure, while procrastination forces heavier reliance on shrinking storage space. 



One promising strategy is to prioritize underground capacity for carbon removal rather than fossil fuel capture.



Direct air capture and <a href="https://www.earth.com/news/abandoned-farmland-can-be-used-for-climate-change-mitigation/">bioenergy</a> with carbon storage could actively draw carbon out of the atmosphere, offering a cooling effect. 



If the full capacity were dedicated to this role, global temperatures could fall by as much as 0.7 °C (1.3 °F), though in practice the impact may be closer to 0.4 °C (0.7 °F) because the climate system doesn’t respond perfectly symmetrically to removal and emission.



<h2 class="wp-block-heading" id="h-reserves-unevenly-spread-worldwide">Reserves unevenly spread worldwide</h2>



Storage is not shared fairly across the globe. The United States, Russia, and Australia hold large, stable reserves. Europe and India lose far more under stricter risk rules.



Meanwhile, some nations in Africa and South America have vast potential but little historic responsibility for emissions. That imbalance raises thorny questions of justice - who gets to use the storage, and on what terms. 



Should wealthy nations pay for access to reserves in countries that contributed less to the crisis? Or should those with the largest reserves prioritize their own development needs first? 



These questions highlight deep inequalities that will shape future climate negotiations.



<h2 class="wp-block-heading" id="h-storage-can-only-buy-time">Storage can only buy time</h2>



Some experts argue the true potential is larger, pointing to decades of safe use in oil and <a href="https://www.earth.com/news/worlds-largest-natural-hydrogen-deposit-discovery-is-worth-a-staggering-184-billion/">gas reservoirs</a>. 



They note that many depleted fields have held fluids securely for millions of years and could continue to hold injected carbon just as reliably.



Supporters of this view see existing infrastructure and technical expertise as proof that storage can operate at much greater scale than the conservative estimates suggest.



Even so, most researchers caution against treating underground storage as a limitless solution. It was never designed to be the final answer to climate change. 



At best, it should function as a bridge - a temporary measure that buys time while renewables expand, low-carbon industries mature, and societies shift away from fossil fuels.



In that sense, storage is less a cure and more a stabilizer, easing the transition without promising permanence. Its real value lies in supporting broader change, not replacing it.



<h2 class="wp-block-heading" id="h-carbon-future-depends-on-choices">Carbon future depends on choices</h2>



The message is clear: underground storage is limited, risky, and unevenly distributed. It can help, but only if used strategically. 



That means prioritizing <a href="https://www.earth.com/news/states-taking-action-on-their-own-can-cut-half-of-u-s-emissions/">emission cuts</a>, expanding clean energy, and reserving storage for removing carbon already in the air.



Treating it as infinite would squander one of the few tools that could still reverse warming, leaving future generations with fewer options, higher risks, and a far narrower path to a stable climate.

Earth has 10x less space for underground carbon storage than we thought - any other ideas?

Imagine Earth has a giant set of underground “storage lockers” where we can tuck away carbon dioxide (CO₂) for centuries so it doesn’t heat the planet. Scientists call this geologic carbon storage.

Extreme rainfall events, defined as the heaviest 5% of rain occurrences in a specific area, are increasing globally. 



As air temperatures rise, scientists expect such events to intensify because warmer air holds more moisture. Recent years have provided alarming examples, with more extreme rainfall fueling widespread flooding.



<h2 class="wp-block-heading" id="h-what-is-extreme-rainfall">What is extreme rainfall?</h2>



Extreme rainfall refers to precipitation events significantly heavier than average for a specific region or period. These events, often defined as the heaviest 5% or 10% of recorded rainfall, vary by location and are influenced by unique <a href="https://www.earth.com/news/extreme-rainfall-gets-an-unpredictable-boost-from-air-pollution/" target="_blank" rel="noreferrer noopener">climatic conditions</a>.



Several meteorological factors drive extreme rainfall. Atmospheric rivers, narrow bands of concentrated moisture, often cause intense downpours. 



Tropical cyclones and convective storms - driven by rising warm, moist air - also contribute to heavy rainfall over localized or widespread areas.



Global warming intensifies these events, as the atmosphere can hold approximately 7% more moisture for every 1°C (1.8°F) rise in temperature.



<h2 class="wp-block-heading" id="h-impact-of-extreme-rainfall">Impact of extreme rainfall</h2>



The frequency and severity of extreme rainfall have increased in recent decades, with significant impacts on ecosystems and communities. 



Beyond flooding, these events cause soil erosion, reduce agricultural productivity, contaminate water supplies through runoff, and increase the risk of landslides in vulnerable regions. 



Notable instances include Hurricane Harvey in 2017, which brought record rainfall to Texas, and the 2018 Kerala floods in India.



Predicting and mitigating the effects of extreme rainfall require advanced climate models, early warning systems, and sustainable infrastructure. 



Measures such as improved urban drainage systems and adaptive urban planning can help reduce damage and protect communities from the growing risks of extreme rainfall.



<h2 class="wp-block-heading" id="h-unexpected-pattern-in-extreme-rainfall">Unexpected pattern in extreme rainfall</h2>



When scientists studied the relationship between <a href="https://www.earth.com/news/rainfall-is-increasingly-unpredictable-due-to-climate-change/" target="_blank" rel="noreferrer noopener">heavy rainfall</a> and local temperatures in different regions, they discovered an unexpected trend. 



In tropical and mid-latitude areas, they observed that extreme rainfall events became less intense when the mean daily temperature exceeded 23°C–25°C (73.4°F–77°F).



This finding was surprising because the prevailing theory suggests that global warming should lead to more intense rainfall events due to increased evaporation and atmospheric moisture. 



Instead of aligning with this theory, the data showed a decline in rainfall intensity at higher temperatures, raising questions about the factors influencing these regional patterns. This result highlights the complex and region-specific nature of climate dynamics.



<h2 class="wp-block-heading" id="h-cooling-effect-of-clouds">Cooling effect of clouds</h2>



Researchers from the Max Planck Institute for Biogeochemistry identified clouds as the key reason behind this puzzling discrepancy.



<a href="https://www.earth.com/news/extreme-rainfall-will-wreak-havoc-on-mountain-ranges-as-warming-climate-turns-snow-to-rain/" target="_blank" rel="noreferrer noopener">Rain</a> forms from clouds, which not only produce precipitation but also block sunlight, cooling the ground beneath them. 



This cooling effect alters the recorded air temperature, creating a bias in the observed link between rainfall intensity and temperature. 



The phenomenon is especially noticeable in tropical regions, where clouds reflect large amounts of sunlight back into space. This reflection amplifies the cooling effect, further complicating the interpretation of temperature and rainfall data in these areas.



<h2 class="wp-block-heading" id="h-factors-behind-extreme-rainfall">Factors behind extreme rainfall </h2>



In a study published in&nbsp;Nature Communications, the researchers devised a method to remove the cooling effect of clouds from mean air temperature data. 



The experts utilized satellite-derived radiation datasets to refine their analysis. Once they corrected for the cloud-induced bias, the relationship between extreme rainfall rates and rising temperatures aligned closely with theoretical predictions and climate model projections.



<blockquote class="wp-block-quote">
"This confirms what is widely expected: Extreme rainfall intensifies in a globally warmer climate," noted Dr. Sarosh Alam Ghausi, lead author and PostDoc at the <a href="https://www.mpg.de/institutes" target="_blank" rel="noreferrer noopener">Max Planck Institute</a>. 



"While heavy <a href="https://www.earth.com/news/september-2024-was-the-second-hottest-month-ever-recorded/" target="_blank" rel="noreferrer noopener">rainfall</a> increases mostly everywhere, we found the largest increases in high temperature-driven heavy rainfall events in tropical humid areas such as in India, Northern Australia, and the Amazon."
</blockquote>



<h2 class="wp-block-heading" id="h-growing-threat-of-flooding">Growing threat of flooding</h2>



As temperatures continue to rise due to climate change, extreme rainfall events are likely to become even more intense. 



Without proactive measures, the risk of devastating floods increases significantly. The findings highlight the need for adaptive strategies to address these heightened risks.



<blockquote class="wp-block-quote">
"These results support the physical expectations that the whole hydrological cycle becomes more intense and extreme with warmer temperatures," noted Dr. Axel Kleidon, senior author and group leader at the Max Planck Institute.



"We will not only see more extreme rainfall rates, but also more intense and longer dry spells in the future."
</blockquote>



<h2 class="wp-block-heading" id="h-impact-of-warming-on-extreme-rainfall">Impact of warming on extreme rainfall </h2>



This study resolves a key uncertainty in understanding how extreme rainfall responds to warming temperatures. 



By accounting for and removing the biases caused by cloud-induced cooling, the researchers confirmed that extreme rainfall patterns align with established <a href="https://www.earth.com/news/droughts-and-extreme-weather-events-are-escalating/" target="_blank" rel="noreferrer noopener">climate predictions</a>. 



The results highlight a crucial reality: as global warming intensifies, the hydrological cycle becomes more extreme. This means heavier rainfall events in some regions, alongside longer and more severe droughts in others. 



With climate change progressing rapidly, these findings emphasize the urgent need for societies to adapt and prepare for increasingly volatile and extreme weather conditions.

Extreme rainfall increases as a direct result of global warming

Extreme rainfall events, defined as the heaviest 5% of rain...

Have you ever noticed how plants wilt visibly during a dry spell? Now, imagine that happening on a much larger scale, affecting entire ecosystems. It's easy to overlook how deeply wildlife depends on rainfall - until a severe drought strikes, leaving a lasting and significant impact.



A recent study reveals that wildlife in the continental United States will face a staggering increase in year-long and multi-year droughts in the coming decades. 



Specifically, year-long droughts are expected to become nearly five times more common from 2050 to 2080 compared to historical levels (1950–2005). Even more dramatically, the frequency of three-year droughts could increase nearly sevenfold.



<h2 class="wp-block-heading" id="h-drought-frequency-and-greenhouse-gases">Drought frequency and greenhouse gases</h2>



“The degree of increased drought exposure for each species in our analysis strongly depends on future greenhouse gas concentrations,” explained Dr. Merijn van den Bosch, the lead author of the study.



The research highlights a grim reality: even with lower greenhouse gas emissions, virtually all vertebrate species will face increased exposure to prolonged droughts. This spells trouble for species already struggling to adapt to occasional <a href="https://www.earth.com/news/climate-change-is-now-the-driving-force-behind-droughts/" target="_blank" rel="noreferrer noopener">drought conditions</a>.



“For example, the endangered giant kangaroo rat, which is native to dry habitats in California, has adapted to occasional short droughts,” noted Dr. van den Bosch.



“However, populations can plummet after multi-year droughts, compounding existing threats, including a loss of nearly all their historic habitat.”



This study predicts that much of the remaining habitat for the giant kangaroo rat will soon experience more frequent and longer droughts. “That does not bode well for this already-endangered species,” said van den Bosch.



<h2 class="wp-block-heading" id="h-drought-in-wildlife-management">Drought in wildlife management </h2>



<a href="https://www.earth.com/news/droughts-and-extreme-weather-events-are-escalating/" target="_blank" rel="noreferrer noopener">Drought conditions</a> are not just a concern for endangered species. The ranges of many game animals - such as ducks, other waterfowl, and ungulates like elk - are also projected to face a significant increase in year-long and three-year droughts.



This trend poses challenges for wildlife management and conservation efforts, potentially disrupting ecosystems and hunting industries.



<h2 class="wp-block-heading" id="h-biodiversity-hotspots-under-threat">Biodiversity hotspots under threat</h2>



To help mitigate the impact of these changes, the researchers focused on areas with high biodiversity and significant projected increases in <a href="https://www.earth.com/news/distress-signals-earths-water-cycle-is-becoming-more-erratic/" target="_blank" rel="noreferrer noopener">drought frequency</a>.



By identifying these regions, they aim to guide adaptive water management and habitat restoration efforts to protect wildlife more effectively.



The scientists used advanced modeling to predict temperature and moisture scenarios based on six different climate projections. They compared these projections with the geographic ranges of 349 bird, 339 mammal, 280 amphibian, and 253 reptile species.



<h2 class="wp-block-heading" id="h-the-most-drought-threatened-region">The most drought-threatened region</h2>



The study revealed that the southwestern United States stands out as the most drought-threatened region.



After adjusting for land area, the Southwest had the highest biodiversity, the most drought-threatened species, and the greatest predicted increase in <a href="https://www.earth.com/news/tiny-sensors-can-detect-dehydration-before-it-destroys-crops/" target="_blank" rel="noreferrer noopener">drought exposure</a>.



“Some of the areas expected to see the greatest increase in drought, such as the southwestern U.S., are already quite dry,” said Dr. Zack Steel, senior author of the study. 



“Many species living in these regions are adapted to periodic droughts, but the concern is that if they are already near the limit of what they can tolerate, the large increase in drought we’re expecting can have grave consequences for these ecosystems and the wildlife that depend on them.”



<h2 class="wp-block-heading" id="h-protecting-wildlife-in-drought-prone-regions">Protecting wildlife in drought-prone regions</h2>



This research highlights the urgent need for proactive measures to address the escalating challenges posed by drought. Adaptive <a href="https://www.earth.com/news/40-percent-of-earths-land-has-became-permanently-drier/" target="_blank" rel="noreferrer noopener">water management</a>, habitat restoration, and conservation strategies tailored to drought-prone regions could help mitigate the impact on wildlife.



The study was conducted by Dr. Merijn van den Bosch, a post-doctoral scientist at <a href="https://www.colostate.edu" target="_blank" rel="noreferrer noopener">Colorado State University</a> and the Rocky Mountain Research Station, and senior author Dr. Zack Steel, a research ecologist with the <a href="https://research.fs.usda.gov/rmrs" target="_blank" rel="noreferrer noopener">Rocky Mountain Research Station</a>. 



Their work highlights the pressing need for innovative approaches to safeguard wildlife in an era of increasing environmental stress.



The message is clear: addressing the root causes of climate change while implementing conservation strategies is essential to protecting vulnerable species. 



As droughts become a more frequent feature of life in the United States, their effects on ecosystems and wildlife cannot be ignored.

Wildlife will struggle to adapt to increasing droughts in the U.S.

Have you ever noticed how plants wilt visibly during a...

A new dawn in environmental protection is emerging - one where artificial intelligence (AI) plays an integral role in understanding and mitigating the effects of chemicals on aquatic life.



It's a fascinating blend of cutting-edge technology and environmental science that could revolutionize our approach to safeguarding water health.



The breakthrough comes from an unexpected source - tiny water fleas known as Daphnia. Researchers have found that these minute crustaceans, which are highly sensitive to changes in water quality, can serve as excellent markers of potential environmental hazards.



<h2 class="wp-block-heading" id="h-unknown-chemical-mixtures-and-aquatic-life">Unknown chemical mixtures and aquatic life </h2>



This innovative study was a collaborative effort involving scientists from the <a href="https://www.birmingham.ac.uk/" target="_blank" rel="noreferrer noopener">University of Birmingham</a>, the Research Centre for Eco-Environmental Sciences (RCEES) in China, and the Hemholtz Centre for Environmental Research (UFZ) in Germany.



The team analyzed water samples from the Chaobai River system near Beijing, a body of water that is exposed to <a href="https://www.earth.com/news/predicting-the-effects-of-pollutants-on-river-ecosystems/" target="_blank" rel="noreferrer noopener">pollutants</a> from several sources, including agriculture, domestic waste, and industry.



Study senior author Professor John Colbourne, director of the University of Birmingham’s Centre for Environmental Research and Justice, elaborated on the research.



“There is a vast array of <a href="https://www.earth.com/news/forever-chemicals-found-in-tap-and-bottled-water-worldwide/" target="_blank" rel="noreferrer noopener">chemicals</a> in the environment. Water safety cannot be assessed one substance at a time," said Professor Colbourne.



"Now we have the means to monitor the totality of chemicals in sampled water from the environment to uncover what unknown substances act together to produce toxicity to animals, including humans.”



<h2 class="wp-block-heading" id="h-potentially-harmful-chemical-mixtures">Potentially harmful chemical mixtures</h2>



Published in the journal Environmental Science and Technology, the study reveals that these tiny <a href="https://www.earth.com/news/water-fleas-may-be-the-solution-to-our-global-water-crisis/" target="_blank" rel="noreferrer noopener">water fleas</a> can indicate the presence (and potential harm) of various mixtures of chemicals in the aquatic environment.



Some chemicals, especially in combination, may affect significant biological processes in aquatic organisms. 



What's particularly concerning is that these chemical combinations can create environmental hazards that are potentially greater than when chemicals are present individually.



"Our innovative approach leverages <a href="https://www.earth.com/news/lifes-rules-natural-selection-change-significantly-often-daphnia/" target="_blank" rel="noreferrer noopener">Daphnia</a> as the sentinel species to uncover potential toxic substances in the environment," explained lead author Dr. Xiaojing Li of the University of Birmingham. 



"By using AI methods, we can identify which subsets of chemicals might be particularly harmful to aquatic life, even at low concentrations that wouldn't normally raise concerns." 



<h2 class="wp-block-heading" id="h-harnessing-ai-for-a-safer-environment">Harnessing AI for a safer environment</h2>



The team's use of advanced artificial intelligence is a game changer. Dr. Jiarui Zhou of the University of Birmingham, who is also co-first author of the paper, led the development of the <a href="https://www.earth.com/news/neuromorphic-computing-where-ai-meets-human-brain/" target="_blank" rel="noreferrer noopener">AI algorithms</a>.



“Our approach demonstrates how advanced computational methods can help solve pressing environmental challenges," said Dr. Zhou.



"By analyzing vast amounts of biological and chemical data simultaneously, we can better understand and predict environmental risks."



<h2 class="wp-block-heading" id="h-chemical-discharge-and-environmental-protection">Chemical discharge and environmental protection </h2>



This breakthrough gives us a new tool to identify previously unknown chemical combinations that pose risks to aquatic life, enabling more comprehensive environmental monitoring. 



The research will also support better-informed regulations for chemical discharge into waterways, ultimately leading to improved environmental protection.



Funding was provided by the Royal Society International Collaboration Award, the European Union's Horizon 2020 research and innovation program, and the Natural Environmental Research Council Innovation People program.



With continued support, AI and the diligent water flea will keep playing their part in protecting our precious water bodies.



<h2 class="wp-block-heading" id="h-chemical-mixtures-that-pose-the-greatest-risk">Chemical mixtures that pose the greatest risk</h2>



Artificial intelligence plays a central role in this research. By leveraging advanced computational methods, the research team has significantly advanced environmental science.



AI enables the analysis of vast datasets, including biological responses of Daphnia and chemical profiles of polluted water samples, thus uncovering intricate patterns and interactions that traditional methods often miss.



One of the most notable outcomes is the ability to identify harmful chemical combinations that might be overlooked with conventional testing. 



Machine learning algorithms can predict which mixtures pose the greatest risks to aquatic life, even at concentrations previously considered safe. 



This predictive capability not only improves the efficiency of monitoring but also provides actionable insights for environmental regulators.



Looking ahead, the potential applications of AI extend beyond water fleas and rivers. Similar approaches can be applied to other ecosystems, paving the way for a comprehensive toolkit for environmental monitoring and conservation.

Chemical mixtures in rivers pose unknown threats to aquatic life

A new dawn in environmental protection is emerging - one...

Desert locusts are notorious for their ability to transform from solitary insects into devastating swarms under specific environmental conditions. 



Triggered by events like intense rainfall, these swarms can devastate crops, pushing food prices higher and leading to starvation and unrest. But now, a new study offers hope for controlling this menace.



<h2 class="wp-block-heading" id="h-the-extent-of-the-problem">The extent of the problem</h2>



Locust swarms are one of nature's most destructive phenomena. Under favorable conditions, locusts form <a href="https://www.earth.com/news/locusts-have-brains-built-for-complex-odor-processing/" target="_blank" rel="noreferrer noopener">large groups</a>, known as swarms, that can devastate entire regions. 



These swarms can grow so massive that they resemble plagues, consuming staggering amounts of crops in their path.



To put this into perspective, a swarm covering just one square kilometer can eat enough food in a single day to feed 35,000 people.



This destruction severely impacts smallholder farmers, who rely on their crops for food and income. Regions like Africa and Asia, where food security is already fragile, are especially vulnerable. The loss of crops not only disrupts local economies but also threatens millions with hunger.



<h2 class="wp-block-heading" id="h-locust-swarms-are-becoming-more-frequent">Locust swarms are becoming more frequent </h2>



The problem is worsening due to climate change. Increased cyclones and heavy rainfall, driven by <a href="https://www.earth.com/news/we-are-in-a-race-against-time-to-save-our-food-supply-from-climate-change/" target="_blank" rel="noreferrer noopener">global warming</a>, create ideal breeding conditions for locusts. These events bring moisture to arid regions, encouraging vegetation growth that provides food for locusts. 



As a result, locust outbreaks are becoming more frequent and severe, posing an even greater threat to food security in vulnerable regions.



<h2 class="wp-block-heading" id="h-predicting-locust-swarms-in-advance">Predicting locust swarms in advance</h2>



Researchers at the <a href="https://www.cam.ac.uk" target="_blank" rel="noreferrer noopener">University of Cambridge</a> have developed a predictive model to tackle locust swarms.



Using weather forecast data from the UK <a href="https://www.metoffice.gov.uk" target="_blank" rel="noreferrer noopener">Met Office</a> and computational models of locust behavior, the system predicts where swarms will move in their search for food and breeding sites. The results enable early interventions, such as targeted pesticide applications.



"During a desert locust outbreak, we can now predict where swarms will go several days in advance, so we can control them at particular sites," said Dr. Renata Retkute, the lead researcher from Cambridge’s Department of Plant Sciences. 



"And if they're not controlled at those sites, we can predict where they'll go next so preparations can be made there."



<h2 class="wp-block-heading" id="h-new-era-of-locust-control">New era of locust control</h2>



Until now, locust swarm predictions have been inconsistent. The researchers’ model represents a shift toward more effective responses. 



By integrating real-time data on locust lifecycles, breeding behaviors, and weather patterns, the model offers both short- and long-term predictions.



"The important thing is to respond quickly if there's likely to be a big locust upsurge, before it causes a major crop loss. Huge swarms can lead to really desperate situations where people could starve," said Professor Chris Gilligan, senior author of the study.



<h2 class="wp-block-heading" id="h-lessons-from-past-locust-swarms">Lessons from past locust swarms</h2>



The urgency of this innovation stems from a massive locust upsurge from 2019 to 2021, which stretched from Kenya to India.



This event devastated key crops like wheat, maize, and sugarcane, leaving many communities struggling. The response was hampered by disjointed information, revealing the need for a comprehensive model.



"The response to the last locust upsurge was very ad-hoc, and less efficient than it could have been. We've created a comprehensive model that can be used next time to control this <a href="https://www.earth.com/news/extreme-weather-dramatically-increases-the-threat-of-desert-locusts/" target="_blank" rel="noreferrer noopener">devastating</a> pest," said Retkute.



<h2 class="wp-block-heading" id="h-a-tested-and-reliable-tool">A tested and reliable tool</h2>



The new model has undergone rigorous testing using surveillance and weather data from the 2019-2021 upsurge. It now stands ready to inform surveillance, early warnings, and management strategies. 



The Food and Agriculture Organization of the United Nations (<a href="https://www.fao.org/home/en" target="_blank" rel="noreferrer noopener">FAO</a>) and national agencies will use it to improve preparedness and response.



"Countries that haven’t experienced a locust upsurge in many years are often ill-prepared to respond, lacking the necessary surveillance teams, aircraft, and pesticides," noted the researchers. 



Climate change further complicates the picture, altering the movement and spread of <a href="https://www.earth.com/news/trillions-of-cicadas-set-to-emerge-in-historic-u-s-invasion/" target="_blank" rel="noreferrer noopener">swarms</a>, making proactive measures like this model essential.



By combining advanced technology and comprehensive data, the predictive model will help mitigate the devastation caused by desert locust swarms. Using this tool, nations can act quickly and decisively, preventing crop loss and protecting food security for millions of people. 



The study is published in the journal <a href="https://journals.plos.org/ploscompbiol/article?id=10.1371/journal.pcbi.1012562" target="_blank" rel="noreferrer noopener">PLOS Computational Biology</a>.

Those massive storms that drench the West Coast aren't going to stay the same. Recent research shows that climate change will reshape atmospheric rivers - but not in the way you might expect. 



While these storms will pack more punch everywhere, their evolution will look quite different in Seattle compared to San Diego.



The findings come from a team at the U.S. National Science Foundation National Center for Atmospheric Research (NSF NCAR), led by scientists Christine Shields and Hui Li. 



Their work reveals how these sky-high rivers of moisture will respond differently to warming, depending on where they make landfall.



<h2 class="wp-block-heading" id="h-contrasting-impacts-of-atmospheric-rivers">Contrasting impacts of atmospheric rivers</h2>



The changes split the West Coast into two distinct stories. 



In Southern California, increasing ocean evaporation will drive the transformation of atmospheric rivers. Head north to Seattle and Portland, and it's a different ball game - there, warmer temperatures in both the ocean and air will call the shots.



These differences matter. By 2100, storms hitting the Pacific Northwest could push ocean waters three times higher than today's storms do. Southern California will see higher storm surges too, but not nearly as dramatic as their northern neighbors.



"On the ground, people will see a different response between the Southern California coast and the Pacific Northwest," said Shields. "It's not a one-size-fits-all situation. You have these <a href="https://www.earth.com/news/atmospheric-rivers-are-shifting-with-global-climate-impacts/" target="_blank" rel="noreferrer noopener">regional responses</a> that can be quite different."



<h2 class="wp-block-heading" id="h-science-behind-the-split">Science behind the split</h2>



The research team relied on advanced computing to understand how climate change will reshape atmospheric rivers. 



Using the powerful Derecho supercomputer at the NSF NCAR-Wyoming Supercomputing Center, they ran detailed climate simulations. 



The simulations captured atmospheric changes every 25 kilometers (15.5 miles) and <a href="https://www.earth.com/news/consecutive-atmospheric-rivers-cause-far-more-damage/" target="_blank" rel="noreferrer noopener">ocean changes</a> every 10 kilometers (6.2 miles), offering high-resolution insights into the behavior of these storms.



The results were surprising. In Southern California, the well-known "Pineapple Express" storms, which transport moisture from Hawaii, are expected to intensify due to increased evaporation from the ocean in a warmer climate. This added evaporation provides more fuel for the storms, making them more powerful.



In the Pacific Northwest, however, the dynamics are different. The storms there will strengthen due to a combination of rising air and ocean <a href="https://www.earth.com/news/global-warming-is-disrupting-the-seasonal-flow-of-rivers/" target="_blank" rel="noreferrer noopener">temperatures</a>. These warming effects will amplify the storms' intensity and lead to more dramatic impacts, such as higher sea levels and increased flooding. 



This regional variation highlights how atmospheric rivers respond differently to climate change, depending on their location.



<h2 class="wp-block-heading" id="h-why-the-difference-matters">Why the difference matters</h2>



These aren't just academic distinctions. Communities along the entire West Coast need to prepare for stronger storms, but their specific challenges will vary by location. The stakes are high - atmospheric rivers already pack a serious punch.



"Atmospheric rivers are like tropical cyclones in that they pack powerful winds and carry enormous amounts of water that can devastate local infrastructure," noted Shields.



"Communities need to understand how they will change in the future so they can adapt and plan."



<h2 class="wp-block-heading" id="h-additional-impacts-of-atmospheric-rivers">Additional impacts of atmospheric rivers</h2>



The impacts don't stop when the rain does. These atmospheric rivers leave their mark on the ocean too, stirring up waters and potentially affecting marine ecosystems long after the storms pass.



"The strong winds and precipitation linked to atmospheric rivers can significantly impact the upper ocean, potentially impacting ocean dynamics and ecosystems over larger spatial scales and longer timescales than the present," said Li.



<h2 class="wp-block-heading" id="h-preparing-for-the-future">Preparing for the future</h2>



This research gives coastal communities crucial information for planning their future. While all regions need to prepare for more intense <a href="https://www.earth.com/news/projected-atmospheric-rivers-could-drench-east-asia/" target="_blank" rel="noreferrer noopener">storms</a>, their specific challenges will depend on location. 



Southern California needs to ready itself for storms supercharged by ocean evaporation, while the Pacific Northwest must prepare for even more dramatic changes driven by warming air and seas.



The study was conducted by researchers from <a href="https://ncar.ucar.edu" target="_blank" rel="noreferrer noopener">NSF NCAR</a>, <a href="https://www.tamu.edu" target="_blank" rel="noreferrer noopener">Texas A&amp;M University</a>, and <a href="https://www.psu.edu" target="_blank" rel="noreferrer noopener">Pennsylvania State University</a>, with funding from the U.S. Department of Energy and NSF.



For West Coast residents, the message is clear: the atmospheric rivers they know today won't be the same ones their children will face. But now, at least, they have a better idea of what's coming their way.



The study is published in the journal <a href="https://www.nature.com/articles/s43247-024-01774-0" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Atmospheric rivers will become more intense as temperatures rise

Those massive storms that drench the West Coast aren't going...

The Winter Solstice, often referred to as “the shortest day of the year,” is an astronomical event that marks the beginning of winter in the Northern Hemisphere.



In this region of the world, the solstice also marks the turning point when days gradually grow longer.



While the solstice represents the start of <a href="https://www.earth.com/news/why-winters-are-getting-colder-while-world-is-getting-warmer/" target="_blank" rel="noreferrer noopener">winter</a>, the coldest temperatures often occur weeks later due to the “seasonal lag,” as the Earth continues losing heat.



Beyond its scientific significance, the winter solstice has profound cultural, spiritual, and historical importance across the globe.



<h2 class="wp-block-heading" id="h-what-is-the-winter-solstice">What is the Winter Solstice?</h2>



The Winter Solstice occurs when one of Earth’s poles is tilted farthest away from the Sun, resulting in the least amount of <a href="https://www.earth.com/news/do-we-actually-benefit-from-daylight-saving-time/" target="_blank" rel="noreferrer noopener">daylight</a>.



This happens because Earth's axis is tilted at approximately 23.5 degrees relative to its orbit around the Sun.&nbsp;



“Earth’s axis may be imagined as an imaginary pole going right through the center of our planet from ‘top’ to ‘bottom.’ Earth spins around this pole, making one complete turn each day. That is why we have day and night,” explained <a href="https://blogs.nasa.gov/Watch_the_Skies/tag/solstice/" target="_blank" rel="noreferrer noopener">NASA</a>.



In the Northern Hemisphere, the Winter Solstice typically occurs between December 20 and 23, with December 21 being the most common date.



On this day, the Sun appears to travel its shortest path across the sky. For those at the Arctic Circle, the Sun may not rise at all, creating 24 hours of darkness. 



Conversely, the Antarctic Circle experiences 24 hours of daylight.



<h2 class="wp-block-heading" id="h-winter-solstice-and-daylight-savings-time-dst">Winter solstice and Daylight Savings Time (DST)</h2>



With all of the talk recently about permanently ending <a href="https://www.earth.com/news/do-we-actually-benefit-from-daylight-saving-time/" target="_blank" rel="noreferrer noopener">Daylight Saving Time (DST)</a>, let's spend a minute discussing how DST can change how we experience the Winter Solstice.



When clocks shift back in the fall to end DST, our mornings get darker earlier because sunrise happens before we wake up. So, on those early winter mornings, it might feel like it’s still night when you roll out of bed. 



On the flip side, the evenings stay a bit lighter longer, giving us a little extra daylight after work or school. This shift can make the dark mornings a bit tougher, especially when the sun barely peeks over the horizon.



However, the impact of DST during the winter solstice also means that our evenings aren’t as dark as they would be if we stayed on standard time year-round. 



This extra evening light can be a nice boost, making it easier to enjoy outdoor activities or simply have more daylight while winding down your day. 



Overall, DST alters the natural daylight patterns around the winter solstice, changing how we perceive and use the limited daylight we get during those chilly winter months.



<h2 class="wp-block-heading" id="h-cultural-significance-of-the-winter-solstice">Cultural significance of the Winter Solstice </h2>



The Winter Solstice has been celebrated across cultures for thousands of years. Early humans observed the solstice as a critical marker of <a href="https://www.earth.com/news/peoples-moral-values-literally-change-with-the-weather/" target="_blank" rel="noreferrer noopener">seasonal change</a>, signifying the gradual return of longer daylight hours and the promise of spring.



<h3 class="wp-block-heading" id="h-stonehenge">Stonehenge</h3>



This ancient monument in England aligns with the solstices, suggesting its builders may have used it as a calendar to track astronomical events.



Constructed in several phases between roughly 3000 BCE and 2000 BCE, <a href="https://www.earth.com/news/stonehenges-famous-altar-stone-has-surprising-origins/" target="_blank" rel="noreferrer noopener">Stonehenge</a> remains a mystery regarding its exact purpose. It may have served as a burial ground or a ceremonial site.



<h3 class="wp-block-heading" id="h-yule-in-norse-tradition">Yule in Norse tradition</h3>



The Norse people celebrated Yule, lighting fires to symbolize the Sun's rebirth and feasting to mark the turning of the season.



Yule coincided with the darkest days of the year. The festival celebrated the return of the Sun and the lengthening of days, symbolizing hope and renewal.



Yule was dedicated to the gods, particularly Odin, who was associated with wisdom, magic, and the Wild Hunt - a ghostly procession believed to occur during this time. Offerings, feasts, and sacrifices were made to gain their favor.



<h3 class="wp-block-heading" id="h-saturnalia-in-ancient-rome-nbsp">Saturnalia in ancient Rome&nbsp;</h3>



Saturnalia was one of the most popular festivals in ancient Rome, held in honor of Saturn, the god of agriculture, wealth, and time.&nbsp;



Celebrated annually in mid-December, the festival originally lasted for a single day (December 17) but eventually expanded to a week. 



The celebration involved feasting, gift-giving, and a temporary social reversal where traditional roles were upended.



<h3 class="wp-block-heading" id="h-dongzhi-in-east-asia-nbsp">Dongzhi in East Asia&nbsp;</h3>



Dongzhi (冬至), meaning "Winter Solstice" in Chinese, is an important festival in East Asia.&nbsp;



Rooted in the philosophy of Yin and Yang, Dongzhi symbolizes the balance and transformation of natural energies as the days begin to lengthen, bringing more light and warmth.



Modern celebrations like Christmas and Hanukkah incorporate elements of these ancient traditions, emphasizing light and hope during the darkest days of the year.



<h2 class="wp-block-heading" id="h-a-universal-reminder">A universal reminder</h2>



The Winter Solstice is more than just an astronomical event; it serves as a reminder of nature’s rhythms and humanity’s enduring connection to the <a href="https://www.earth.com/news/anthropic-principle-we-live-in-a-universe-fine-tuned-to-support-life/" target="_blank" rel="noreferrer noopener">universe</a>. It symbolizes resilience, as the darkest day paves the way for the return of light.&nbsp;



Across millennia, it has inspired wonder, reflection, and celebration - a testament to the timeless bond between Earth, its inhabitants, and the heavens.



<h2 class="wp-block-heading" id="h-a-spiritual-turning-point">A spiritual turning point</h2>



The solstice encourages people to look inward, reflect on the past year, and set intentions for the year ahead, aligning with the natural pause of winter.



This occasion represents the balance and cycles of life, urging us to embrace both light and shadow in our personal journeys.

Winter Solstice: The shortest day of the year has arrived

The Winter Solstice, often referred to as “the shortest day...

In the depths of planet Earth, a hidden microbial world thrives under extreme conditions that are beyond the reach of our regular perception.



This extraordinary and invisible ecosystem harbors an abundance of life forms that flourish in environments such as gold mines, aquifers, and deep boreholes in the seafloor.



But how do these below-the-surface microbiomes compare to the vibrant ecosystems bathed in Earth's sunlight?



<h2 class="wp-block-heading" id="h-discovering-the-microbial-deep-dwellers">Discovering the microbial deep dwellers</h2>



Researchers have now investigated this question in a first-of-its-kind comprehensive endeavor undertaken at the <a href="https://www.mbl.edu/" target="_blank" rel="noreferrer noopener">Marine Biological Laboratory</a> (MBL).



What they found was incredibly rich <a href="https://www.earth.com/news/microbial-life-soil-planet-warming-global-carbon-cycle/" target="_blank" rel="noreferrer noopener">microbial diversity</a> in certain subsurface habitats, which extended up to 491 meters (1,610 feet) below the seafloor and 4,375 meters (14,300 feet) below ground level in terrestrial habitats.



This unprecedented revelation hints at vast, unexplored, subsurface sources of diversity, and presents possible opportunities for finding new compounds and medicines.



The study holds potential for identifying how cells adapt to extremely energy-scarce environments. The findings may also be useful in the search for <a href="https://www.earth.com/news/expanding-the-search-for-extraterrestrial-life/" target="_blank" rel="noreferrer noopener">extraterrestrial life</a>.



<h2 class="wp-block-heading" id="h-microbial-diversity-below-the-surface">Microbial diversity below the surface</h2>



The study's lead scientist, MBL associate scientist Emil Ruff, addressed some of the common assumptions about life below the Earth's surface.



“It’s commonly assumed that the deeper you go below the <a href="https://www.earth.com/news/mystery-of-how-diamonds-reach-the-earths-surface-finally-solved/" target="_blank" rel="noreferrer noopener">Earth’s surface</a>, the less energy is available, and the lower is the number of cells that can survive,” noted Ruff. 



“Whereas the more energy present, the more diversity can be generated and maintained - as in tropical forests or coral reefs, where there’s lots of sun and warmth."



However, the study’s findings tell a different story. In some subsurface habitats, microbial diversity can easily match or surpass the diversity on the surface.



This was found to be especially true for marine environments and for <a href="https://www.earth.com/news/living-microbes-discovered-in-2-billion-year-old-rocks/" target="_blank" rel="noreferrer noopener">microbes</a> in the Archaea domain.



<h2 class="wp-block-heading" id="h-a-tale-of-two-realms">A tale of two realms</h2>



The study, which took almost a decade to complete, was also one of the first to compare marine and terrestrial environments in terms of microbial diversity and community composition.



While the experts found that the marine and terrestrial microbiomes differed greatly in composition, their level of diversity was similar. This finding gives rise to a fundamental ecological principle.



“There’s a very clear divide between <a href="https://www.earth.com/news/diverse-life-forms-from-800-million-years-ago-redefine-evolution/" target="_blank" rel="noreferrer noopener">life forms</a> in the marine and in the terrestrial realms, not just in the surface, but also in the subsurface. The selective pressures are very different on land and in the sea, and they select for different organisms that have a hard time living in both realms," explained Ruff.



<h2 class="wp-block-heading" id="h-microbes-in-low-energy-environments">Microbes in low-energy environments</h2>



The existence of a vast reservoir of microbes kilometers deep - both under our feet and beneath the seafloor - was first broadly recognized by scientists in the mid-1990s.



Now, scientists estimate that between 50 and 80 percent of Earth’s microbial cells live in the subsurface sediments, where energy availability is significantly lower than on the sunlit surface.



The study suggests that potentially half of Earth's microbial diversity can be found in <a href="https://www.earth.com/news/human-activities-great-harm-earth-subsurface-deep-interior/" target="_blank" rel="noreferrer noopener">subsurface zones</a>.



In addition, the findings point towards a fascinating phenomenon: in these low-energy environments, life appears to be slowed down to an absolute minimum. Some subsurface cells are estimated to divide only once every 1,000 years. 



These microbes live on completely different timescales and could provide intriguing insights about aging.



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



If planets like <a href="https://www.earth.com/news/hidden-water-found-on-mars-would-cover-the-planet-over-one-mile-deep/" target="_blank" rel="noreferrer noopener">Mars had liquid water</a> at some point in their history, the rocky ecosystems below their surface could resemble those currently on Earth.



“The energy would be very low; the organisms’ generation times would be very long. Understanding deep life on Earth could be a model for discovering if there was life on Mars, and if it has survived,” said Ruff.



<h2 class="wp-block-heading" id="h-microbiomes-of-diverse-locations-on-earth">Microbiomes of diverse locations on Earth</h2>



Past studies of microbial life on Earth’s surface and subsurface aren't scarce, but synthesizing the data was challenging due to inconsistencies in methodology across different research groups.



However, in 2016, a breakthrough method allowed for a consistent dataset to compare more than 1,000 samples from 50 marine and terrestrial ecosystems.



Samples from around the world were sent to MBL, where scientists used identical routines to sequence and analyze the microbial DNA present. 



This consistent methodology allowed for the first direct comparison of microbiomes from vast and diverse locations.



Ultimately, the research serves as a foundation for exposing the rich tapestry of life forms that inhabit the invisible worlds below the Earth’s crust.



As we continue to explore these subsurface habitats, we stand to learn much about the adaptability and resilience of life in its myriad forms.



The full study was published in the journal <a href="https://www.science.org/doi/10.1126/sciadv.adq0645" target="_blank" rel="noreferrer noopener">Science Advances</a>.

Half of Earth's microbial life may be hiding beneath the surface

In the depths of planet Earth, a hidden microbial world...

Despite their reputation as buzzing nuisances, flies serve a critical role as some of the Earth's most prolific pollinators. A new study led by Penn State scientists suggests that flies are increasingly at risk due to rising global temperatures.



An international team of researchers examined the heat tolerance of various bee and fly species in tropical and subtropical regions of the Americas.&nbsp;



The results indicate that flies are more vulnerable to <a href="https://www.earth.com/news/how-climate-change-is-buzzing-off-bumblebee-senses/" target="_blank" rel="noreferrer noopener">warming climates</a> than bees, since bees can handle significantly higher temperatures and occupy a broader range of habitats.



“Bees and flies are essential for pollinating plants, both in the wild and in agriculture,” said Margarita López-Uribe, an expert in pollinator health at <a href="https://www.psu.edu/" target="_blank" rel="noreferrer noopener">Penn State</a> and lead author on the study. “However, these vital insects are declining due to habitat loss, pesticides, disease and the growing threat of climate change.”



<h2 class="wp-block-heading" id="h-flies-are-underappreciated-yet-vital-pollinators">Flies are underappreciated yet vital pollinators</h2>



Flies, second only to <a href="https://www.earth.com/news/bees-do-not-learn-to-be-cooperative-it-is-in-their-genes/" target="_blank" rel="noreferrer noopener">bees</a> in terms of the volume of crops and habitats they pollinate, play a crucial role in sustaining wild ecosystems.&nbsp;



By facilitating the reproduction of numerous plant species, flies help maintain biodiversity and provide resources for countless other organisms. They also increasingly contribute to agriculture - for example, flies serve as the primary pollinators of cocoa trees, the source of chocolate.



A 2020 analysis of global crops found that the 105 most widely planted crops benefiting from pollinators represent more than $800 billion in gross economic value. Among these pollinators, flies, specifically hoverflies and blowflies, consistently ranked just behind bees.



“It's time we gave flies some more recognition of their role as pollinators,” López-Uribe said. “Flies have a significant role, but they don't get as much attention - and they are vulnerable in all the same ways that bees are.”



<h2 class="wp-block-heading" id="h-flies-bees-and-climate-change">Flies, bees, and climate change </h2>



Because insects cannot easily control their body temperatures, rising global temperatures present a serious challenge. 



To assess how different <a href="https://www.earth.com/news/pollinators-face-extinction-risk-due-to-climate-change/" target="_blank" rel="noreferrer noopener">pollinators</a> might cope, the research team measured the “critical thermal maximum” (CTMax) - the highest temperature at which insects can still move - of both bees and flies.



They found that bees can tolerate substantially warmer conditions than flies. On average, bees had a CTMax 2.3 degrees Celsius higher than that of flies.&nbsp;



Additionally, bees foraging in cooler morning hours proved more heat-tolerant than those active in warmer afternoons.&nbsp;



Geographic factors also mattered - pollinators living at high-elevation tropical sites showed lower CTMax values than their counterparts in subtropical areas.



<h2 class="wp-block-heading" id="h-data-collection-across-the-americas">Data collection across the Americas</h2>



The study’s data collection occurred during COVID-19 lockdowns, so international students from Penn State and other universities conducted research in their home countries.&nbsp;



Instead of traveling, students worked with equipment sent to them, gathering measurements in their own kitchens and backyards.



“We sent out all of the equipment to do the study to students throughout the U.S. and South America,” López-Uribe said. “These students were collecting the data in their houses, using their kitchens to understand the thermal ecology these insects could withstand.”



“We effectively were able to provide an international research experience without being able to travel internationally.”



<h2 class="wp-block-heading" id="h-flies-battling-climate-change">Flies battling climate change </h2>



The findings suggest that insects from cooler, high-altitude environments, such as Cajicá in Colombia, are particularly susceptible to even slight temperature increases.&nbsp;



Since flies are often the primary pollinators in alpine and subarctic regions, their reduced ability to withstand warming could jeopardize entire ecosystems.



“In alpine and subarctic environments, flies are the primary pollinator,” López-Uribe said. “This study shows us that we have entire regions that could lose their primary pollinator as the <a href="https://www.earth.com/news/how-climate-change-is-buzzing-off-bumblebee-senses/" target="_blank" rel="noreferrer noopener">climate</a> warms, which could be catastrophic for those ecosystems.”



As climate change continues to reshape global temperatures, understanding the vulnerabilities of flies - as well as bees - will be key in guiding conservation efforts.&nbsp;



Without recognizing and protecting the essential pollination services flies provide, communities may face declining biodiversity, reduced crop yields, and unstable ecological networks in the years to come.



The study is published in the <a href="https://dx.doi.org/10.17161/jom.vi122.22505" target="_blank" rel="noreferrer noopener">Journal of Melittology</a>.

Flies are more vulnerable to climate change than bees

Despite their reputation as buzzing nuisances, flies serve a critical...

When marathon runners train, their minds typically focus on mileage, nutrition, and gear. Yet recent research from the Brown University School of Public Health suggests that runners may also need to think about the air they breathe on race day.&nbsp;



According to a new study published in <a href="https://link.springer.com/article/10.1007/s40279-024-02160-8" target="_blank" rel="noreferrer noopener">Sports Medicine</a>, higher levels of fine particulate matter in the air are linked to slower average marathon finish times.



“Runners at that level are thinking about their gear, their nutrition, their training, the course, even the weather,” said study author Elvira Fleury, who conducted the research while enrolled as a graduate student at <a href="https://www.brown.edu/" target="_blank" rel="noreferrer noopener">Brown University</a> and is now a doctoral student at <a href="https://www.harvard.edu/" target="_blank" rel="noreferrer noopener">Harvard University</a>. 



“Our results show that those interested in optimizing <a href="https://www.earth.com/news/mental-fatigue-impairs-athletic-performance/" target="_blank" rel="noreferrer noopener">athletic performance</a> should consider the effect of <a href="https://www.earth.com/news/understanding-how-air-pollution-forms-may-help-us-prevent-it/" target="_blank" rel="noreferrer noopener">air pollution</a>, as well.”



<h2 class="wp-block-heading" id="h-large-scale-analysis-across-major-marathons">Large-scale analysis across major marathons</h2>



The study drew on finish times from 1,506,137 male and 1,058,674 female participants who ran in nine major marathons throughout the United States - including Boston, Houston, and Los Angeles - between 2003 and 2019.&nbsp;



By combining publicly available race data with a sophisticated statistical model developed by Allan Just, an associate professor of epidemiology and environment and society at Brown, the researchers could determine the amount of fine particulate matter at various points along each course.



“This really sophisticated spatial-temporal model of particulate matter allowed us to plot pollution at every mile of every course,” Fleury said. “Without a model like this, it wouldn't have been possible to look at so many different marathons in different states across different years.”



<h2 class="wp-block-heading" id="h-air-pollution-and-marathon-performance">Air pollution and marathon performance </h2>



Fine particulate matter, known as PM2.5, consists of airborne particles smaller than 2.5 microns in diameter and originates from sources like <a href="https://www.earth.com/news/intense-forest-fires-leave-scorched-earth-heating-the-planet-faster/" target="_blank" rel="noreferrer noopener">forest fires</a>, vehicle emissions, and industrial activities.&nbsp;



Analyzing the data, the researchers found that every 1 µg/m³ increase in PM2.5 was associated with slower finish times: on average, 32 seconds slower among men and 25 seconds slower among women. The effect was particularly evident among faster-than-median runners, suggesting that even elite athletes might be affected.



Although these time differences may seem small, Fleury pointed out that they matter greatly in elite competitions, where the margin between victory and defeat or achieving a personal record can be just a few seconds.



“Think of all the effort, time and money that a professional runner like Eliud Kipchoge put into trying to break the world record and run a marathon in less than two hours,” Fleury said. “Every second matters.”



<h2 class="wp-block-heading" id="h-marathon-runners-exposed-to-air-pollution">Marathon runners exposed to air pollution </h2>



While previous research has linked air pollution to health issues like <a href="https://www.earth.com/news/your-diet-may-save-your-life-six-key-foods-lower-the-risk-of-heart-disease/" target="_blank" rel="noreferrer noopener">heart disease</a>, lung disease, and even mortality, this study examined its impact on the athletic performances of fit, well-trained individuals.&nbsp;



The researchers suggested that exposure to air pollution could lead to increased blood pressure, constricted blood vessels, reduced lung function, respiratory discomfort, or short-term cognitive difficulties - factors that together might slow a runner’s pace.



“People who can complete a marathon are generally quite healthy, and we can assume they have honed their cardiorespiratory fitness,” said study author Joseph Braun, a professor of epidemiology at Brown’s School of Public Health.&nbsp;



“This study revealed a negative impact from air pollution, even at levels below current health-based standards, on these very healthy people. This means that air pollution can be a health risk not just for those who are elderly or susceptible - it can negatively affect even the most healthy and well-trained among us.”



<h2 class="wp-block-heading" id="h-b-roader-implications-of-the-research">Broader implications of the research </h2>



The results serve as a reminder that if air pollution can hamper marathon runners - often among the healthiest individuals - then the general population may also face health risks from polluted air.&nbsp;



The researchers concluded that efforts to lower pollution through regulation of power generation, industry, and transportation not only protect public health but may also help athletes perform at their peak.



For runners striving to set new personal records, paying attention to air quality forecasts could be one more step toward success.&nbsp;



For policymakers and environmental advocates, these findings underscore the importance of continuing efforts to reduce air pollution, ensuring a healthier environment for everyone - from elite athletes to casual joggers and beyond.

The giant hornet, once feared for threatening insects, agriculture, and human comfort, has been eradicated from its foothold in the United States.



Officials in Washington State have announced that the invasive species, long feared to be on a path to permanent establishment, is no longer lurking in the region where it first appeared. This development, five years in the making, has calmed local growers and everyday folks who once wondered whether the hornet’s presence would spread beyond that northwest corner.



<h2 class="wp-block-heading" id="h-a-narrow-escape-from-the-giant-hornet">A narrow escape from the giant hornet</h2>



The campaign against the giant hornet began when stunned beekeepers discovered eerily decapitated honeybees. Aggressive trapping and tracking techniques soon followed. Specialists from state agencies donned thick suits and carefully approached <a href="https://www.earth.com/news/oriental-hornets-have-the-highest-alcohol-tolerance-of-any-animal/" target="_blank" rel="noreferrer noopener">hornet</a> nests, using delicate methods to remove them. It took years for the last hornet to turn up empty-handed. This outcome did not come easily. The <a href="https://agr.wa.gov/departments/insects-pests-and-weeds/insects/hornets" target="_blank" rel="noreferrer noopener">Washington State Department of Agriculture</a> and the United States Department of Agriculture's Animal and Plant Health Inspection Service, represented by pest program manager Sven Spichiger and associate deputy administrator <a href="https://www.aphis.usda.gov/news/agency-announcements/aphis-plant-protection-quarantine-selects-new-leader-its-emergency" target="_blank" rel="noreferrer noopener">Nicole Russo</a>, stand as key figures in this success story.



<h2 class="wp-block-heading" id="h-from-the-front-lines">From the front lines</h2>



The individuals who led the fight against this insect had been worried about the possibility of a permanent invader.&nbsp;



“As an entomologist, I’ve been doing this for over 25 years now, and it is a rare day when the humans actually get to win one against the insects,” said <a href="https://www.researchgate.net/profile/Sven-Erik-Spichiger" target="_blank" rel="noreferrer noopener">Sven Spichiger</a> at the end of the months-long 2023 tracking season. The dramatic effort to find and eradicate the nests pushed everyone involved to remain vigilant, setting traps, training local port inspectors and working tirelessly to address every reported sighting.



<h2 class="wp-block-heading" id="h-nationwide-view">Nationwide view</h2>



The project required help from many. 



Observant residents phoned tip lines. Field teams outfitted giant hornets with tiny trackers. Nests discovered near the Canadian border were carefully sealed off. 



With continued support, officials now say the species is no longer present in that part of Washington. Despite this, many agencies remain on their toes. The United States Department of Agriculture's Animal and Plant Health Inspection Service, called the successful effort a <a href="https://www.aphis.usda.gov/news/agency-announcements/aphis-action-victory-over-worlds-largest-hornet-species" target="_blank" rel="noreferrer noopener">“landmark achievement”</a> to celebrate.



<h2 class="wp-block-heading" id="h-lingering-questions-about-the-giant-hornet">Lingering questions about the giant hornet</h2>



Experts have not identified the precise route by which the giant hornet originally arrived. Some suggest it might have hidden inside a shipping container. Without clear proof, there is no guarantee a fresh introduction will never happen again. Potential <a href="https://www.earth.com/news/why-are-hornets-so-successful-as-invasive-species/" target="_blank" rel="noreferrer noopener">future detections</a> will likely trigger a swift response. New sightings remain possible, and teams intend to keep watch. Officials in Washington say that any further activity will face the same intense scrutiny as before. Past lessons will guide all future efforts, so no one wants to take chances.



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



Outside the United States, fears linked to hornets have rattled others. 



In parts of Europe, alarm spread after a related species, the southern giant hornet, surfaced in northern Spain, prompting researchers to warn that more outbreaks could follow if left unchecked. The wide distribution of similar insects shows that this is not a contained issue. Scientists point to climate conditions, global shipping patterns, and changing ecosystems as reasons why these insects appear in unlikely places.



<h2 class="wp-block-heading" id="h-more-than-a-name">More than a name</h2>



The hornet once caused a buzz in the media under various nicknames. Many remember it being called the “Asian giant hornet” and “murder <a href="https://www.earth.com/news/hornets-are-the-most-important-pollinators-for-some-plants/" target="_blank" rel="noreferrer noopener">hornet</a>,” but specialists have moved toward a name they find more accurate. 



As per the <a href="https://www.entsoc.org/publications/common-names/better-common-names-project" target="_blank" rel="noreferrer noopener">Entomological Society of America</a>, calling it the “northern giant hornet” better suits its native range while also reducing problematic associations. That shift may help everyone talk about the insect without tying it to any single region or prompting unnecessary assumptions.



<h2 class="wp-block-heading" id="h-what-really-mattered">What really mattered</h2>



The giant hornet’s potential to damage honeybee colonies and other beneficial insects raised alarms among ecologists, beekeepers and farmers. A single hornet nest, if left alone, can cause serious losses in crucial pollinator populations. Many experts knew that if the species spread, it would be no small matter. <a href="https://www.semanticscholar.org/paper/A-Bionomic-Sketch-of-the-Giant-Hornet%2C-Vespa-a-Pest-Matsuura-Sakagami/67e9b6a08e424b124bae2965e0d292e55d93ad43" target="_blank" rel="noreferrer noopener">Studies</a> on the behavior of the northern giant hornet (Vespa mandarinia) suggest that these hornets can quickly invade hives, and their stings pack a painful punch for humans and other animals as well.



<h2 class="wp-block-heading" id="h-lessons-learned-from-the-giant-hornets">Lessons learned from the giant hornets</h2>



One positive takeaway from this situation is that clear communication and community involvement can pay off. Early <a href="https://www.earth.com/news/alien-invasion-yellow-legged-hornet-spotted-in-the-u-s-for-the-first-time/" target="_blank" rel="noreferrer noopener">detection</a> and rapid response efforts worked. The strong network of officials, scientists and residents raised the alarm, tracked every possible hornet and prevented it from spreading to other areas. Officials have also given training and supplies to various inspectors at key points of entry. The entire scenario, though tense, underlined how people can come together to stop a serious threat before it turns into an ongoing crisis.

Victory: Invasive 'murder hornets' have been completely eradicated from the US

It is well known that Arctic ice captures most headlines when it comes to climate change, but the icy waters around Antarctica are also showing troubling shifts. 



In 2023, Antarctic sea ice hit record lows, a development that left researchers scratching their heads as they observed a surprising surge in ocean changes beneath the now more exposed Southern Ocean surface. This year-over-year shift is no small blip, and it appears that 2024 will surge past the record lows of 2023, continuing this disturbing trend. It represents a dramatic event that scientists have long feared might happen but hoped to avoid. 



<h2 class="wp-block-heading" id="h-a-new-winter-without-cover">A new winter without cover</h2>



As the protective ice blanket thinned, the ocean underneath became more <a href="https://www.earth.com/news/emergency-meeting-reveals-the-alarming-extent-of-antarcticas-ice-loss/" target="_blank" rel="noreferrer noopener">vulnerable</a>. 



Without a solid covering, heat from the water escaped in far greater amounts than seen before. The result was a measurable spike in warmth shifting into the air above the waves. At the same time, storm activity began ramping up, turning the region into a hotbed of atmospheric commotion. 



According to recent <a href="https://www.nature.com/articles/s41586-024-08368-y" target="_blank" rel="noreferrer noopener">research</a>, the low ice levels in 2023 allowed for unprecedented ocean heat loss and triggered more frequent storms. 



<h2 class="wp-block-heading" id="h-changing-antarctic-sea-ice">Changing Antarctic sea ice</h2>



This study was conducted by Professor <a href="https://scholar.google.com/citations?user=b-RiXNQAAAAJ&amp;hl=en" target="_blank" rel="noreferrer noopener">Simon Josey</a>, an expert on ocean-atmosphere interaction at the UK’s National Oceanography Centre (<a href="https://noc.ac.uk/" target="_blank" rel="noreferrer noopener">NOC</a>).&nbsp;



The work paints an unsettling picture of a Southern Ocean entering a new era, where <a href="https://www.earth.com/news/antarctic-ice-sheet-patterns-point-to-rapid-melting-risks/" target="_blank" rel="noreferrer noopener">conditions</a> once considered extreme are becoming common. 



Researchers say these harsh conditions could repeat in coming years if <a href="https://earthobservatory.nasa.gov/images/152547/antarctic-sea-ice-at-near-historic-lows" target="_blank" rel="noreferrer noopener">sea ice</a> fails to recover.



<h2 class="wp-block-heading" id="h-science-behind-the-antarctic-sea-ice-conditions">Science behind the Antarctic sea ice conditions</h2>



Shifts in Antarctic <a href="https://nsidc.org/sea-ice-today" target="_blank" rel="noreferrer noopener">sea ice</a> do not only matter for penguins and seals. The Southern Ocean is a key player in our climate system. It stores carbon, moves heat around the planet, and supports large-scale ocean currents. As ice declines, the ocean’s personality changes. According to the research team’s findings, years with low ice cover will likely feature more intense winter weather and unusual ocean properties. According to the findings, years with minimal <a href="https://www.earth.com/news/how-are-intense-heat-waves-affecting-life-in-antarctica/" target="_blank" rel="noreferrer noopener">sea ice</a> are likely to experience heightened storm activity and significant transformations in ocean characteristics. Simon Josey explained that this trend highlights the ongoing impact of Antarctic sea ice loss which could cascade into long-term disruptions in global climate systems.



<h2 class="wp-block-heading" id="h-rethinking-what-we-thought-we-knew">Rethinking what we thought we knew</h2>



The new results mark a dramatic departure from previous assumptions about the stability and resilience of Antarctica’s icy <a href="https://www.earth.com/news/antarcticas-peace-is-at-risk-as-nations-race-for-its-resources/" target="_blank" rel="noreferrer noopener">environment</a>. 



Before 2023, <a href="https://journals.ametsoc.org/view/journals/clim/35/14/JCLI-D-21-0918.1.xml">scientists</a> did not anticipate such a sharp decline in sea ice and the related jump in ocean heat release. “I didn’t expect to see a real-world ice decline as large as that observed in 2023 with such strong consequences for the ocean heat loss,” said <a href="https://journals.ametsoc.org/view/journals/clim/35/14/JCLI-D-21-0918.1.xml" target="_blank" rel="noreferrer noopener">Dr. Holly Ayres</a>, formerly at the <a href="https://www.reading.ac.uk" target="_blank" rel="noreferrer noopener">University of Reading</a> and now at NOC.



<h2 class="wp-block-heading" id="h-a-heavier-ocean-in-ice-free-zones">A heavier ocean in ice-free zones</h2>



One of the most striking changes involves the <a href="https://floats.pmel.noaa.gov/sites/default/files/atoms/files/gcj_4j.pdf" target="_blank" rel="noreferrer noopener">density of surface waters</a>. When the ocean loses heat, the top layer becomes denser. With more ice-free regions, the water is sinking more readily into the depths. “The massive increase in ocean heat loss to the atmosphere is increasing the density of water at the sea surface to values not previously seen,” said Professor Josey.



<figure class="wp-block-image aligncenter size-full"><a href="https://www.earth.com/wp-content/uploads/2024/12/declining-Antarctic-sea-ice_Schematic-representation_credit-NOC_1m.jpg" target="_blank" rel="noreferrer noopener"><img src="https://www.earth.com/wp-content/uploads/2024/12/declining-Antarctic-sea-ice_Schematic-representation_credit-NOC_1s.webp" alt="Declining Antarctic Sea-ice from the NOC Near Present Day NEMO ocean model simulation (credit Dr Adam Blaker).

Colors show the difference of June to July 2023 from June to July 1991-2020, blue shows less ice around much of Antarctica.</figcaption></figure>



These shifts in density can influence the formation of heavier water masses that can travel far into the ocean’s interior, affecting how heat and nutrients flow across the globe. Over time, the unusual movement of these waters could even alter patterns of <a href="https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2024GL111229" target="_blank" rel="noreferrer noopener">Antarctic bottom water</a>, which helps shape global ocean circulation. 



<h2 class="wp-block-heading" id="h-cracks-in-the-global-weather-puzzle">Cracks in the global weather puzzle</h2>



Far-reaching <a href="https://www.earth.com/news/when-will-the-antarctic-ice-sheet-collapse/" target="_blank" rel="noreferrer noopener">effects</a> may emerge. Scientists have long known that the Southern Ocean plays an outsize role in managing Earth’s heat and carbon storage. Now, with the ice slipping away, and more energy escaping into the air, there is a chance that <a href="https://arxiv.org/abs/1602.01393?utm_">distant regions</a> could feel the pinch in the form of altered weather patterns. The team at NOC has indicated that it’s too early to confirm whether 2023 and its record-breaking sea-ice decline marked the onset of a fundamental shift in the amount of Antarctic sea ice. The puzzle includes potential changes in how warm waters move beneath the surface, which could set the stage for shifting conditions that ripple far beyond Antarctica but only time will tell.



<h2 class="wp-block-heading" id="h-need-for-new-antarctic-sea-ice-simulations">Need for new Antarctic sea ice simulations</h2>



Scientists stress that these findings are not just about one odd year. 



They argue that understanding what is happening now can help us predict what might come next. Improved climate models are needed to understand why this happened and what might follow.



“We need to use our ocean and climate simulations to understand how the major increase in heat loss and increased surface water density in regions of declining Antarctic sea ice impacts the wider ocean circulation,” said Professor Josey.



<h2 class="wp-block-heading" id="h-gazing-ahead-with-cautious-eyes">Gazing ahead with cautious eyes</h2>



No one wants to see a permanent slide toward less <a href="https://www.earth.com/news/antarctica-is-greening-at-an-unprecedented-rate/">ice</a> and more climate chaos. However, if low sea ice cover conditions repeat in future winters, these extraordinary shifts could become the new normal.



What matters now is how researchers worldwide pull together their data, simulations, and knowledge to figure out what this all means for the planet.&nbsp;

Rapid Antarctic sea ice loss is causing severe storms around the world

It is well known that Arctic ice captures most headlines...

The Greenland Ice Sheet, part of which is shown in this image of Jakobshavn Glacier, is now melting at an incredibly rapid pace, pushing sea levels upward while upsetting global weather patterns. 



Precise measurements of the ice sheet’s changing shape and volume matter greatly at this point in Earth's history because accurate data helps scientists understand what's coming next.



Until recently, getting this information was tricky. 



Now, two advanced missions, ESA’s CryoSat and NASA’s ICESat-2, have joined forces to offer data that reaches far beyond old limits. 



Their combined measurements deliver a more complete view that was not possible before.



<h2 class="wp-block-heading" id="h-measuring-greenland-ice-melt">Measuring Greenland ice melt</h2>



As of today, scientists have recorded the first measurements of the Greenland Ice Sheet’s shape changes using both <a href="https://www.esa.int/Applications/Observing_the_Earth/FutureEO/CryoSat" target="_blank" rel="noreferrer noopener">CryoSat</a> and <a href="https://icesat-2.gsfc.nasa.gov/" target="_blank" rel="noreferrer noopener">ICESat-2</a> satellites.



This work is led by researchers from the UK Centre for Polar Observation and Modelling (<a href="https://cpom.org.uk/" target="_blank" rel="noreferrer noopener">CPOM</a>). Lead author and CPOM researcher Nitin Ravinder has confirmed that these missions are able to capture changes in ice elevation with impressive accuracy.



<h2 class="wp-block-heading" id="h-technologies-from-different-skies">Technologies from different skies</h2>



To measure the <a href="https://www.earth.com/news/speed-of-greenland-ice-melt-confirmed-to-be-rapidly-increasing-climate-change/" target="_blank" rel="noreferrer noopener">rapid loss</a> of the ice all across Greenland, one of the mission satellites relies on radar, and the other uses a laser. 



Radar can measure through clouds but needs careful adjustments because it can pass into the ice surface before bouncing back.



Laser measurements track the actual surface but cannot see through clouds. 



These tools stand at opposite ends, yet when put together, they form a better pair than either could alone. 



In fact, a new study published in Geophysical Research Letters notes that CryoSat and ICESat-2 measurements of Greenland Ice Sheet elevation change agree within 3% of what is actually happening.



This stronger confidence means if one mission fails, the other can still <a href="https://www.earth.com/news/greenland-ice-loss-tracked-by-new-gps-system-on-a-daily-basis/" target="_blank" rel="noreferrer noopener">keep track of ice changes</a>.



“We are very excited to have discovered that CryoSat and ICESat-2 are in such close agreement. Their complementary nature provides a strong motivation to combine the data sets to produce improved estimates of ice sheet volume and mass changes," says lead author and CPOM researcher Nitin Ravinder.



"As ice sheet mass loss is a key contributor to global sea level rise, this is incredibly useful for the scientific community and policymakers.”

<h2 class="wp-block-heading" id="h-greenland-ice-and-natural-beauty">Greenland, ice, and natural beauty</h2>



Greenland, the world’s largest island, sits between the Arctic and Atlantic Oceans. It is mostly <a href="https://www.earth.com/news/greenland-ice-sheet-discovery-transforms-sea-level-predictions/" target="_blank" rel="noreferrer noopener">covered with thick ice</a>, and its glaciers run from the heart of the island to its shores. 



There are small towns along the coastal edges where people make a life that ties closely to the environment. 



Long winters and brief summers shape a culture centered on fishing, hunting, and a respect for nature’s power. 



The capital, Nuuk, brings together old traditions and new ways of living in a place where weather is a big player in daily life.



<h2 class="wp-block-heading" id="h-melting-ice-and-everyday-lives">Melting ice and everyday lives</h2>



A warming climate makes <a href="https://www.earth.com/news/massive-glacial-outburst-observed-in-greenland-for-the-first-time/" target="_blank" rel="noreferrer noopener">Greenland’s glaciers break apart</a> and slip into the ocean. As they melt, sea levels climb, and coastal cities thousands of miles away face the threat of water creeping up their streets. 



Wildlife in Greenland itself struggles when the ice they depend on thins. Polar bears, seals, and walruses have fewer safe spots to rest and hunt. 



For local people, the loss of stable ice can disrupt fishing and hunting practices. Shifts in ocean currents triggered by fresh meltwater also <a href="https://www.earth.com/news/greenland-transformation-ice-melt-plant-growth-vegetation-cascading-effects/" target="_blank" rel="noreferrer noopener">change weather patterns</a>, and that can spell trouble for everyone.



<h2 class="wp-block-heading" id="h-real-numbers-behind-greenland-ice-melt">Real numbers behind Greenland ice melt</h2>



Between 2010 and 2023, Greenland’s ice sheet thinned by an average of four feet In the ice sheet’s ablation zone, where summer melting outpaces winter snowfall, the average thinning reached 20 feet. 



The worst thinning was at Sermeq Kujalleq, also known as Jakobshavn Isbræ, with a peak thinning of 220 feet. At Zachariae Isstrøm in the northeast, peak thinning hit about 250 feet. 



Altogether, the ice sheet shrank by 7,700 cubit feet over a 13-year stretch. It lost more than 1300 cubic feet in 2012 and 2019, matching extreme conditions. 



According to the study, these changes affect not only local environments but <a href="https://www.earth.com/news/atmospheric-rivers-are-shifting-with-global-climate-impacts/" target="_blank" rel="noreferrer noopener">global weather patterns</a>.



“CryoSat has provided an invaluable platform for understanding our planet’s ice coverage over the past 14 years, but by aligning our data with ICESat-2, we’ve opened new avenues for precision and insight," says Tommaso Parrinello, CryoSat Mission Manager at <a href="https://www.esa.int" target="_blank" rel="noreferrer noopener">ESA</a>. 



"This collaboration represents an exciting step forward, not just in terms of technology but in how we can better serve scientists and policymakers who rely on our data to understand and mitigate climate impacts.” 



<h2 class="wp-block-heading" id="h-aligning-with-sister-missions">Aligning with sister missions</h2>



<a href="https://earth.esa.int/eogateway/missions/cryosat/cryo2ice" target="_blank" rel="noreferrer noopener">The Cryo2ice campaign</a> that began in 2020 let scientists put CryoSat and ICESat-2 measurements side by side. 



By adjusting CryoSat’s orbit, ESA allowed the two satellites to gather radar and laser data over the same areas, almost at the same time. 



This set the stage for measuring snow depth from space with a level of accuracy that simply did not exist before.



“It is great to see that the data from ‘sister missions’ are providing a consistent picture of the changes going on in Greenland,” says Thorsten Markus, project scientist for the ICESat-2 mission at <a href="https://www.nasa.gov" target="_blank" rel="noreferrer noopener">NASA</a>.



“Understanding the similarities and differences between radar and lidar ice sheet height measurements allow us to fully exploit the complementary nature of those satellite missions." 



Studies like this are critical to put a comprehensive time series of the ICESat, CryoSat-2, ICESat-2, and, in the future, CRISTAL missions together.



<h2 class="wp-block-heading" id="h-greenland-ice-and-earth-s-future">Greenland ice and Earth's future</h2>



The accurate data now available will help in decisions that governments must make soon. Timely, reliable information on ice thickness shifts can guide planning for coastal infrastructure. 



It matters to millions of people who live near shores in every corner of the planet, and for those who rely on stable weather patterns to grow food and make a living.



ESA’s CryoSat and NASA’s ICESat-2 work as a team to keep an eye on the ice. Together, they paint a detailed picture of changes in Greenland. 



That picture gives experts and leaders better tools for understanding the future and figuring out how to adapt.



The full study was published in the journal <a href="https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2024GL110822" target="_blank" rel="noreferrer noopener">Geophysical Research Letters</a>.

</div><figcaption class="wp-element-caption">Researchers found a correlation between Alzheimer's disease and traffic pollution.</figcaption></figure>



<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.

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.

<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.

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.



The full study was published in the <a href="https://linkinghub.elsevier.com/retrieve/pii/S1617138125000780" target="_blank" rel="noreferrer noopener">Journal for Nature Conservation</a>.

Wildlife tunnels save millions of amphibians

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

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



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



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

</div></figure>



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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