There’s a heat-driven health crisis creeping in - not with coughing or fevers in a doctor’s office, but with buzzing mosquitoes.



Dengue fever, a disease that used to stick mostly to tropical zones, is breaking borders and heading toward cities and countries that never had to worry about it before. The reason? It’s getting warmer.



<a href="https://www.earth.com/news/mosquito-borne-diseases-are-a-growing-threat-in-a-warming-world/">Dengue</a> is far more than a nuisance. The illness often starts with high fever, headaches, and body aches. In some cases, it spirals into internal bleeding, organ failure, and death.



Once mostly seen in places like Brazil and the Philippines, it’s now on track to affect millions more across both Asia and the Americas.



<h2 class="wp-block-heading" id="h-temperature-and-dengue-transmission">Temperature and dengue transmission </h2>



Until now, scientists had a pretty good hunch that heat played a role in dengue’s spread. What this new study makes clear is just how big that role is - and how dangerous the trend could become.



The analysis looked at 1.4 million records of dengue across 21 countries, mainly in Central and South America, plus Southeast and South Asia. The research shows that even small increases in average temperature are already making dengue infections worse and more widespread.



“The effects of temperature were much larger than I expected,” said Marissa Childs, the lead author from the <a href="https://www.summer.uw.edu/">University of Washington</a>. “Even small shifts in temperature can have a big impact for dengue transmission, and we’re already seeing the fingerprint of climate warming.”



<h2 class="wp-block-heading" id="h-the-mosquito-s-sweet-spot">The mosquito’s sweet spot</h2>



Dengue doesn’t spread well in just any heat. It thrives in a narrow band of temperatures. The peak danger zone? Around 82°F. That’s the sweet spot where <a href="https://www.earth.com/news/mosquitoes-use-thermal-infrared-vision-to-track-and-bite-humans/">mosquitoes</a> are most active and the dengue virus replicates fast.



This means that as previously cooler cities and regions warm up, they’re becoming perfect breeding grounds for mosquitoes that carry dengue. This includes major population centers in Mexico, Peru, and Brazil. Many are just now reaching that danger zone, and that’s where the biggest spikes are expected.



The study found that hotter areas already above this optimal temperature might actually see slight dips in dengue spread. But those declines don’t come close to canceling out the massive increases elsewhere. The total global impact is still a steep rise in infections.



<h2 class="wp-block-heading" id="h-millions-of-infections-linked-to-heat">Millions of infections linked to heat</h2>



Between 1995 and 2014, warmer temperatures were responsible for 18% of dengue infections across the 21 countries studied. That’s not a future estimate - it’s already happened. 



Based on current rates, over 4.6 million extra dengue cases have been caused by climate-driven warming every year.



Looking ahead, things could get worse, and fast. Depending on how much <a href="https://www.earth.com/news/greenhouse-gas-emissions-reach-another-all-time-high/">greenhouse gas emissions</a> rise, cases could jump another 49% to 76% by 2050. That means more than double the current number of dengue infections in places that are already home to over 260 million people.



“Many studies have linked temperature and dengue transmission,” said Erin Mordecai, senior author of the study. “What’s unique about this work is that we are able to separate warming from all the other factors that influence dengue - mobility, land use change, population dynamics - to estimate its effect on the real-world dengue burden." 



"This is not just hypothetical future change but a large amount of human suffering that has already happened because of warming-driven dengue transmission.”



<h2 class="wp-block-heading" id="h-new-places-new-risks">New places, new risks</h2>



The numbers in the study might actually be lower than the real totals. The research didn’t include places where data is unreliable or hard to get - such as large parts of India and Africa. 



The analysis also doesn’t fully cover areas where dengue is still emerging, like parts of the United States and Europe.



But signs are showing up. Dengue cases have already been reported in California, Texas, Florida, Hawaii, and even southern parts of Europe. As people move, cities grow, and the <a href="https://www.earth.com/news/climate-variables-can-predict-future-mosquito-activity/">virus</a> evolves, the risks are rising.



<h2 class="wp-block-heading" id="h-how-to-slow-the-spread">How to slow the spread</h2>



The study points to two ways forward: prevention and preparation. On the prevention side, aggressive action to cut carbon emissions would slow down global warming and reduce heat-driven spread of dengue. 



This strategy would require more investment in clean energy and fewer emissions from fossil fuels.



But even with strong prevention efforts, adaptation is critical. Health systems need to be ready. Mosquito control programs have to expand. And access to new vaccines will matter more than ever.



“<a href="https://www.earth.com/news/cities-are-largely-unprepared-for-the-effects-of-climate-change/">Climate change</a> is not just affecting the weather - it has cascading consequences for human health, including fueling disease transmission by mosquitoes,” Mordecai said.



"Even as the U.S. federal government moves away from investing in climate mitigation and climate and health research, this work is more crucial than ever for anticipating and mitigating the human suffering caused by fossil fuel emissions.”



What this study shows isn’t just that dengue is spreading. It proves that climate change is already making people sick in ways that were once hard to measure. The suffering isn’t tomorrow’s problem - it’s today’s reality. And unless big changes happen fast, that reality is only going to get worse.



The full study was published in the journal Proceedings of the National Academy of Sciences.

Rising heat is supercharging dengue and spreading it into new regions

There’s a heat-driven health crisis creeping in - not with coughing or fevers in a doctor’s office, but with buzzing mosquitoes. Dengue fever, a disease that used to stick mostly to tropical zones, is breaking borders and heading toward cities and countries that never had to worry about it before. The reason?

Envision some of the famous seafood dishes, like a beautifully cooked large yellow croaker. Now consider a critical yet unseen component of that seafood's journey to our plate - the cold chain. 



This chain plays an underestimated role in delivering fresh, high-quality seafood. At the same time, it is also a primary cause behind the spoilage of seafood, presenting unique challenges that researchers are eager to resolve.



<h2 class="wp-block-heading" id="h-cold-chain-dilemma">Cold chain dilemma</h2>



Cold chain logistics, an often unmentioned player in the food industry, holds the key to the freshness of our&nbsp;<a href="https://www.earth.com/news/can-america-achieve-seafood-self-sufficiency/" target="_blank" rel="noreferrer noopener">seafood</a>.&nbsp;



However, inconsistencies in temperature control during transit and handling can promote conditions ideal for microbial growth, enzymatic activity, and chemical reactions, which may reduce fish quality. This is where our story gets interesting.



New research from <a href="http://www.zjgsu.edu.cn/index.html" target="_blank" rel="noreferrer noopener">Zhejiang Gongshang University</a> is shedding light on this critical issue, taking us a step closer to mitigating quality loss during transit and offering valuable insights into improving the management of the seafood cold chain.



Led by Dr. Yanbo Wang, an ambitious team of researchers embarked on a study to examine the effects of temperature fluctuations on the large yellow croaker, a mariculture species noted for its economic value and perishable nature.



<h2 class="wp-block-heading" id="h-combating-supply-complications">Combating supply complications</h2>



The team simulated actual <a href="https://www.earth.com/news/seafood-is-underestimated-source-of-pfas-exposure-in-humans/">cold chain conditions</a> to gauge how temperature fluctuations from 4°C (39°F) to 16°C (61°F) affect the integrity of large yellow croaker.



Their findings? A distinct correlation between inconsistency in temperatures and compromised fish quality.



By carefully tracking changes in total viable counts (TVC), total volatile basic nitrogen (TVB-N) content, K values, and thiobarbituric acid reactive substances (TBARS) values - key spoilage indicators - the team uncovered that higher temperature variations led to significant increases in all these spoilage markers.



<h2 class="wp-block-heading" id="h-quality-deterioration-markers">Quality deterioration markers</h2>



Perhaps one of the most fascinating results of the study was the identification of 81 volatile compounds, including aldehydes, ketones, and nitrogenous compounds.&nbsp;



The presence and concentration of these compounds swing wildly with temperature changes. Notably, 2-pentanone and ethyl acetate stood out as possible signs of quality degradation, offering new means to monitor seafood freshness.



“Our study clearly demonstrates how temperature fluctuations can dramatically affect seafood quality, reinforcing the need for stringent cold chain management. Identifying specific volatile compounds as markers of spoilage provides a new tool for monitoring seafood freshness throughout the supply chain," noted Dr. Yanbo Wang, the study's lead author. 



"These insights are critical for producers and distributors to minimize quality loss during transport and ensure food safety. By advancing our understanding of temperature effects on seafood, we can drive improvements across the entire cold chain logistics system.”



<h2 class="wp-block-heading" id="h-transforming-the-seafood-supply-chain">Transforming the seafood supply chain</h2>



By solving the cold chain riddle, the study's influence transcends the realm of quality control. It opens doors to developing enhanced monitoring systems for early detection of quality degradation - a game-changer for the seafood supply chain. 



By identifying stalwart spoilage indicators such as TVC and volatile compounds like 2-pentanone and ethyl acetate, the research paves the way for new packaging and transport technologies that maintain stable temperatures. 



Ultimately, the insights from the study could help reduce food waste and improve consumer safety.



Furthermore, the research highlights the pressing need for updated regulatory standards to ensure better temperature management in cold chain logistics. This holds profound implications for a <a href="https://www.earth.com/news/dietary-shift-to-forage-fish-could-prevent-millions-of-deaths/" target="_blank" rel="noreferrer noopener">safer and higher-quality journey</a> from ocean to table.



The study was supported by esteemed entities like the National Natural Science Foundation of China and the Zhejiang Provincial Natural Science Foundation of China, among others.



<h2 class="wp-block-heading" id="h-cold-chain-revolution">Cold chain revolution</h2>



As we begin to understand the nuances of maintaining temperature stability in transit, we find ourselves at the precipice of a revolution in seafood logistics. 



Whether it is reducing food waste, ensuring consumer safety, or enhancing industry practices, it is clear that the cold chain holds the keys to our seafood's future.



And as for that delicious large yellow croaker dish? The next time you savor it, perhaps you'll spare a thought for the cold chain journey the fish endured to reach your plate.

Seafood spoilage: Hidden dangers in the cold chain

Envision some of the famous seafood dishes, like a beautifully...

Pathogens traveling on the wind may be more common than we realize.&nbsp;A recent study has revealed a surprising discovery - potentially harmful microbes, including antibiotic-resistant bacteria, travel vast intercontinental distances on high-level winds.



The study, which is the first of its kind, focused on data from tropospheric aircraft surveys. 



Scientists led by Professor Xavier Rodó at the&nbsp;<a href="https://www.isglobal.org/en/" target="_blank" rel="noreferrer noopener">Barcelona Institute for Global Health</a>&nbsp;uncovered an unexpected diversity of bacteria and fungi, some of which are pathogenic to humans.&nbsp;



"Around 30-40% of the microbes were potentially pathogenic species, either well-recognized human pathogens or opportunistic pathogens," noted Professor Rodó. This can affect people with weakened immune systems.



<h2 class="wp-block-heading" id="h-high-flying-pathogens">High-flying pathogens</h2>



While concentrations of microbes in the air are too low to cause immediate illness, Professor Rodó warned that the real concern lies in the potential for these airborne microbes to introduce&nbsp;<a href="https://www.earth.com/news/antibiotic-resistant-bacteria-have-been-found-in-clouds/" target="_blank" rel="noreferrer noopener">antibiotic-resistant</a>&nbsp;genes into new environments.



"The genes are transported in living organisms, so they have a greater likelihood of passing once the aerosol settles," added Dr. Allen Haddrell of the&nbsp;<a href="https://www.bristol.ac.uk/" target="_blank" rel="noreferrer noopener">University of Bristol</a>, who was not involved in the study.



The resilient&nbsp;<a href="https://www.earth.com/news/how-do-deadly-microbes-travel-around-the-world-so-quickly/" target="_blank" rel="noreferrer noopener">microbes</a>&nbsp;were found covering distances up to 1,200 miles, attached to dust particles in a study conducted over Japan.&nbsp;



These dust particles, originating from farm fields in northeastern China, transported more than 300 species of bacteria and 260 types of fungi across the skies.&nbsp;Similar wind patterns likely carry microbes across other regions of the globe.



<h2 class="wp-block-heading" id="h-pathogens-and-winds-of-resistance">Pathogens and winds of resistance</h2>



The sheer number of microbial species surprised the researchers, as their initial goal was simply to analyze the chemistry of the&nbsp;<a href="https://www.earth.com/news/great-salt-lake-drying-up-causing-major-dust-pollution/" target="_blank" rel="noreferrer noopener">dust</a>&nbsp;particles.&nbsp;



"This is a word of caution that we should be changing our view of the air," said Professor Rodó. He pointed out that these microbes endured extreme environmental conditions, protected by the dust particles they traveled with.



Some of the species identified include well-known&nbsp;<a href="https://www.earth.com/news/organic-vegetables-often-harbor-human-pathogens/" target="_blank" rel="noreferrer noopener">human pathogens</a>&nbsp;such as E. coli, Staphylococcus saprophyticus, and Clostridium difficile.&nbsp;



Protected from ultraviolet light and dehydration, these pathogens remained viable and capable of replicating after long journeys.



<h2 class="wp-block-heading" id="h-pathogens-in-the-wind-samples">Pathogens in the wind samples</h2>



Dust samples were collected at altitudes between 0.6 and 1.9 miles above Japan, beyond the planetary boundary layer (PBL). At these altitudes, winds travel faster and farther due to reduced friction with the ground.&nbsp;



Chemical analysis confirmed the dust’s long-range origin, containing rare elements such as zirconium and hafnium, which were traced to agricultural regions in China.



"The chances of getting an infectious dose (via high-level winds) must be considerably less than when encountering an infected person on an airplane," noted Professor Chris Thomas from the <a href="https://www.birmingham.ac.uk/" target="_blank" rel="noreferrer noopener">University of Birmingham</a>.



However, Professor Thomas noted that the dust and chemicals accompanying the microbes may pose a greater health risk as air pollution.



<h2 class="wp-block-heading" id="h-what-does-this-mean-for-humans">What does this mean for humans?</h2>



Though the immediate risk of infection from these high-altitude travelers is low, the presence of antibiotic-resistant microbes raises concerns about global health.&nbsp;



Professor Rodó emphasized that the findings reveal an underappreciated dimension of antibiotic resistance. The experts concluded that the troposphere could act as a reservoir and long-distance transporter of various microbial species, including harmful ones.



This highlights the potential for airborne pathogens to contribute to antibiotic resistance, posing significant public health concerns that require further investigation. Understanding these dynamics is crucial for developing strategies to combat the spread of resistant bacteria.



<h2 class="wp-block-heading" id="h-pathogens-and-antibiotic-resistance">Pathogens and antibiotic resistance</h2>



The research opens up new questions about the spread of antibiotic resistance via wind-borne pathogens and dust particles.



Dr. Haddrell warned that this is going to be a problem over the long term as more resistant&nbsp;strains of bacteria&nbsp;may find new environments in which to thrive.



The study also raises broader concerns about air pollution, with dust and chemicals contributing to airborne health risks.



While the airborne pathogens may not pose an immediate threat to most people, their ability to survive long-distance travel and carry antibiotic-resistant genes should prompt further investigation.&nbsp;



The study adds yet another layer of complexity to our global ecosystem, highlighting the need for ongoing research into the invisible travelers riding the wind.



The study is published in the journal&nbsp;<a href="https://www.pnas.org/doi/10.1073/pnas.2404191121" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.

Pathogens ride high-altitude winds over vast distances

Pathogens traveling on the wind may be more common than...

A recent study of 10,000 nine to 11 year olds has found that each additional day of exposure to wildfire smoke and other types of extreme forms of air pollution raises the risk of mental health issues in children.



“We found that a greater number of days with fine particulate air pollution levels above EPA standards was associated with increased symptoms of mental illness, both during the year of exposure and up to one year later,” said lead author Harry Smolker, a research associate at <a href="https://www.colorado.edu/">CU Boulder</a> Institute of Cognitive Science.



This study, published in the journal <a href="http://dx.doi.org/10.1289/EHP13427">Environmental Health Perspectives</a>, was published at the same time as smoke from Southern California wildfires covers much of the Western U.S., extending as far away as Las Vegas and some parts of Colorado.&nbsp;



<h2 class="wp-block-heading" id="h-severe-levels-of-particulate-matter">Severe levels of particulate matter</h2>



Although annual average air quality has improved in recent decades due to limits on greenhouse emissions from combustion engines, more frequent wildfires have led to a new critical problem: a larger number of days with severe levels of particulate matter in the air.



“We are entering a new age in which we are experiencing unprecedented levels of exposure to particulates multiple times a year,” Smolker said. “We need to understand what these extreme events are doing to young people, their brains and their behavior.”



<h2 class="wp-block-heading" id="h-wildfire-smoke-and-mental-health">Wildfire smoke and mental health</h2>



Although scientists have already known that air pollution can harm the lungs and the heart, they have only recently started to explore its impact on <a href="https://www.earth.com/news/air-pollution-mental-health-children/">mental health</a>.



Studies have shown that PM 2.5 (particulate matter with a diameter of less than 2.5 micrometers), is small enough to cross the blood-brain barrier, leading to inflamed tissue, damaged cells, and immune responses which can trigger both acute and long-term brain changes.



Experts have previously found that hospital admissions for depression, psychosis, and suicide attempts increase in adults on days with a high level of <a href="https://www.earth.com/news/air-pollution-linked-to-increased-risk-of-dementia/" target="_blank" rel="noreferrer noopener">air pollution</a>.



When pregnant women are exposed to high levels of particulate matter, their children are at a higher risk of developing motor deficits and cognitive impairments later in life.&nbsp;



However, this new study is among the first to examine potential impacts on young people, whose brains are in a process of continuous development.



<h2 class="wp-block-heading" id="h-wildfire-smoke-exposure">Wildfire smoke exposure</h2>



The scientists analyzed data from 10,000 pre-teens participating in the <a href="https://abcdstudy.org/" target="_blank" rel="noreferrer noopener">Adolescent Brain Cognitive Development (ABCD) Study</a> - the largest longitudinal study of brain development and children’s health conducted in the U.S.&nbsp;



To determine how many days in 2016 children were exposed to PM2.5 levels exceeding the level the <a href="https://www.epa.gov/" target="_blank" rel="noreferrer noopener">Environmental Protection Agency</a> (EPA) considers safe (35 micrograms per cubic meter), the researchers examined participant addresses and historical air quality data.



The investigation revealed that approximately one-third were exposed to at least one day above the EPA standard, with one participant exposed to unsafe levels for 173 days. The highest level of exposure was 199 micrograms per cubic meter, which is over five times the level deemed safe.



<h2 class="wp-block-heading" id="h-mental-health-impacts-of-wildfires">Mental health impacts of wildfires</h2>



The experts looked at parent questionnaires at four time points during three years. They discovered that, across both genders, each additional day of exposure to unsafe levels of PM2.5 increased the probability of an adolescent developing symptoms of depression, <a href="https://www.earth.com/news/fear-and-anxiety-the-mental-health-impacts-of-wildfires/" target="_blank" rel="noreferrer noopener">anxiety</a> and other mental health issues up to one year later.



These findings came after taking into account a wide variety of possibly confounding factors, such as race, socioeconomic status and, most importantly, parental mental health. Even when parents did not report any symptoms of mental illness, their children frequently did.



“This suggests that PM2.5 exposure may have specific impacts on youth distinct from impacts on their parents,” Smolker said.



<h2 class="wp-block-heading" id="h-repeated-exposure-is-most-damaging-nbsp">Repeated exposure is most damaging&nbsp;</h2>



Repeated high levels of PM2.5 exposure had a larger influence on risk than annual averages or maximum levels did, an alarming finding suggesting that each additional day of exposure counts.



For each day of unsafe exposure, risk increased up 0.1 points on average on a scale from 1 to 50.



“This is relatively small, but not trivial,” Smolker said, emphasizing that PM2.5 is only one of the large variety of pollutants in the “exposome,” the collection of environmental exposures which shape children’s development. “Collectively they can add up.”&nbsp;



<h2 class="wp-block-heading" id="h-cognitive-impacts-of-air-pollution">Cognitive impacts of air pollution </h2>



Some children may be genetically predisposed to be even more vulnerable to the cognitive impact of air pollution



Although PM2.5 can arise from many sources, including traffic and industry, the experts suspect that most of the exposures in the study were due to wildfire <a href="https://www.earth.com/news/wildfire-smoke-creates-conditions-that-favor-more-fires/" target="_blank" rel="noreferrer noopener">smoke</a>.



“Wildfire smoke events are becoming more and more common, and this study adds to a growing body of evidence that they can impact our health,” said co-author Colleen Reid, a geographer at CU Boulder.



“The current study concluded that the number of days of PM2.5 exposure above US EPA standards during late childhood was associated with higher concurrent levels of internalizing symptoms across females and males, even after considering effects of other temporal patterns of exposure,” wrote the study authors.&nbsp;



“Notably, this association remained when accounting for parental psychopathology, suggesting PM2.5 exposure may have specific impacts on youth distinct from impacts on their parents.”

Wildfire smoke exposure linked to mental health issues

A recent study of 10,000 nine to 11 year olds...

Antarctica’s rapidly shrinking sea ice could have a significant impact on the food supply of seabirds that breed far from the continent, according to new research. 



Most of the world’s albatrosses and their relatives, the petrels, breed on islands in the Southern Ocean surrounding Antarctica. These seabirds rely on the nutrient-rich waters affected by the seasonal sea ice for feeding.



<h2 class="wp-block-heading" id="h-monitoring-the-movement-of-seabirds">Monitoring the movement of seabirds</h2>



A study led by <a href="https://www.durham.ac.uk/" target="_blank" rel="noreferrer noopener">Durham University</a> in collaboration with the <a href="https://www.bas.ac.uk/" target="_blank" rel="noreferrer noopener">British Antarctic Survey</a> (BAS) used satellite tracking technology to monitor the movements of these birds. 



The researchers discovered that albatrosses and petrels travel vast distances to reach areas affected by <a href="https://www.earth.com/news/record-low-antarctic-sea-ice-and-rapid-melting-pace-stuns-climate-scientists/" target="_blank" rel="noreferrer noopener">sea ice</a>, known as the Antarctic seasonal sea ice zone. 



This is where they either feed in the nutrient-dense waters left behind after the ice melts each summer or, in the case of southern giant petrels, scavenge for seals found on the ice itself.



Historically, Antarctica had not experienced the dramatic loss of sea ice seen in the Arctic. However, in the past five years, Antarctic sea ice has begun to retreat more rapidly.&nbsp;



<h2 class="wp-block-heading" id="h-seabirds-may-struggle-to-find-food">Seabirds may struggle to find food</h2>



The study suggests that as sea ice continues to decline, seabirds may be forced to fly further from their breeding grounds in search of food, or they may encounter shifts in where their food sources are located. This, in turn, could disrupt the ecosystems to which these seabirds belong.



Published in the journal <a href="http://dx.doi.org/10.1016/j.pocean.2024.10333" target="_blank" rel="noreferrer noopener">Progress in Oceanography</a>, the study provides new insight into how these changes in sea ice could affect bird populations that breed far from the continent. 



Study lead author Ewan Wakefield is a scientist from Durham University’s Department of Geography.



“Every winter, the sea freezes around Antarctica, with sea ice covering tens of millions of square miles. We found that <a href="https://www.earth.com/news/study-uncovers-4000-years-of-foraging-behavior-among-albatrosses/" target="_blank" rel="noreferrer noopener">albatrosses</a> and large petrels travel hundreds of miles, some far into the area covered by this sea ice, and we think that they do this to feed,” said Wakefield. 



“In that case, Antarctica’s receding sea ice, driven by climate change, could affect not just the penguins, familiar to many people, that breed on the continent, but also huge numbers of seabirds breeding hundreds or thousands of miles away.”



<h2 class="wp-block-heading" id="h-many-species-rely-on-sea-ice">Many species rely on sea ice</h2>



The experts analyzed the movements of seven species of albatross and large <a href="https://www.earth.com/news/extreme-snowstorms-impact-breeding-success-of-petrels/" target="_blank" rel="noreferrer noopener">petrel</a>, including northern and southern giant petrels, white-chinned petrels, and several species of albatross. 



Using satellite data collected between 1992 and 2023, the researchers tracked 2,497 foraging trips by 1,289 seabirds from South Georgia, a sub-Antarctic island about 1,000 miles from Antarctica. The research revealed that all seven species used sea ice-affected waters, though in different ways.&nbsp;



For example, albatrosses largely avoided ice-covered areas, likely because of the difficulty in flying or landing on the ice. Instead, they fed in regions where the ice had melted and released concentrated nutrients.&nbsp;



Southern giant petrels, on the other hand, ventured hundreds of miles into the pack ice during spring, likely scavenging for seals.



<h2 class="wp-block-heading" id="h-shrinking-sea-ice-levels">Shrinking sea ice levels</h2>



The researchers also observed a seasonal pattern, with birds moving north and south in sync with plankton blooms in the oceans - a phenomenon known as green wave surfing.



During the period when the satellite data was recorded, Antarctic sea ice was relatively stable. However, recent summers have seen earlier retreats and record-low levels of seasonal sea ice.&nbsp;



<h2 class="wp-block-heading" id="h-escalating-impacts-on-seabirds-nbsp">Escalating impacts on seabirds&nbsp;</h2>



According to Richard Phillips, co-author and leader of the Higher Predators and Conservation Group at BAS, these declines in sea ice, exacerbated by climate change, could worsen the already unsustainable <a href="https://www.earth.com/news/nearly-all-seabirds-have-ingested-microplastics/" target="_blank" rel="noreferrer noopener">human impacts</a> on seabird populations.



While the study sheds light on how seabirds interact with sea ice-affected habitats, researchers acknowledge some limitations. They do not yet know exactly what the birds are eating in these areas, which future tracking and dietary studies aim to reveal.&nbsp;



Additionally, the resolution of the tracking data wasn’t fine enough to show exactly how birds interact with sea ice on a small scale. Finally, the study didn’t cover the entire breeding period for several species, so it remains unclear how they might use these habitats during other times of the year.



Despite these limitations, the study underscores the importance of understanding how Antarctic sea ice dynamics influence not only the continent’s wildlife but also the seabirds that breed far away in the Southern Ocean.

Shrinking sea ice makes it harder for seabirds to find food

Antarctica’s rapidly shrinking sea ice could have a significant impact...

In an astounding revelation, scientists have shed new light on the contributing factors behind Amazon rainforest carbon emissions. 



Using high-resolution aerial scans and cutting-edge computational modeling, the researchers have identified wildfires, storms, and selective logging as the dominant culprits.



These disturbances, once thought to have a lesser impact, surprisingly outweigh traditional clear-cutting practices in terms of Amazon carbon loss.



This new understanding challenges long-held assumptions and highlights the urgent need to address multiple drivers of degradation to protect the Amazon’s crucial role in regulating Earth's climate.

Instead of relying on conventional methods, the researchers used drones equipped with state-of-the-art light detection and ranging (LiDAR) sensors.



These sophisticated devices allowed the experts to accurately map and measure tree biomass and <a href="https://www.earth.com/news/circular-economy-needed-to-reduce-americas-carbon-emissions/" target="_blank" rel="noreferrer noopener">carbon emissions</a> across vast stretches of Brazilian forests.



"Here, we estimate changes of forest aboveground carbon (AGC) stocks attributed to both human-induced degradation and natural disturbances, and the postdisturbance regrowth over an area of active land use change in the southern Brazilian Amazon," noted the researchers.



With the backing of NASA's Jet Propulsion Laboratory, the scientists uncovered alarming findings. Of the estimated 90.5 million tons of carbon lost annually, a staggering 60 million tons were attributed to forest degradation caused by <a href="https://www.earth.com/news/wildfires-in-old-growth-amazon-forests-increased-by-152-in-2023/" target="_blank" rel="noreferrer noopener">wildfires</a>, storms, and selective logging.



In contrast, only about 24 million tons could be traced back to clear-cutting, challenging the traditional view of deforestation as the primary driver of carbon loss in the Amazon.

Study co-author K.C. Cushman is an environmental scientist and expert in data analytics at the <a href="https://www.ornl.gov/?gad_source=1&amp;gclid=CjwKCAjwxY-3BhAuEiwAu7Y6sz_5c-_3HT-Qu7Wo4kTAuc8pjs6xQqv5i_IiLOxqGcEn-S4Su1nfFRoCAa8QAvD_BwE">Oak Ridge National Laboratory</a>.



"It's important to calibrate models to local conditions to achieve the best estimates," noted Cushman. "Tree shape varies a lot from one setting to another even if it's the same species."



The research highlights the urgency of addressing these newly uncovered triggers for <a href="https://www.earth.com/news/the-amazon-rainforest-is-approaching-widespread-collapse/" target="_blank" rel="noreferrer noopener">rainforest</a> carbon emissions.



Cushman and his team are now applying similar cutting-edge methodologies to study carbon dynamics in forests across the U.S. Southeast and also in tropical regions, further broadening the understanding of global <a href="https://www.earth.com/news/study-explores-forest-degradation-in-the-atlantic-rainforest/" target="_blank" rel="noreferrer noopener">forest degradation</a>.



While clear-cutting was once considered the primary villain behind carbon emissions in rainforests, the new findings shift the focus to other key contributors.



Coordinated action is urgently needed to safeguard the planet's rainforests, which play an essential role in stabilizing Earth's climate.



<h2 class="wp-block-heading" id="h-amazon-carbon-loss-and-global-warming">Amazon carbon loss and global warming</h2>



The Amazon rainforest is often referred to as the “lungs of the Earth” due to its vast capacity to absorb and store carbon dioxide, acting as a critical buffer against climate change. 



Covering an estimated 5.5 million square kilometers, the Amazon plays a crucial role in regulating the planet’s climate by sequestering massive amounts of carbon from the atmosphere, which helps mitigate global warming.



Recent findings emphasize that disturbances such as wildfires, storms, and selective logging significantly disrupt this delicate balance, leading to a surge in carbon emissions. 



These destructive forces not only release stored carbon but also weaken the forest's ability to regenerate and continue functioning as a major <a href="https://www.earth.com/news/extreme-weather-can-flip-forests-from-carbon-sinks-to-carbon-sources/" target="_blank" rel="noreferrer noopener">carbon sink</a>.



<h2 class="wp-block-heading" id="h-efforts-to-mitigate-climate-change">Efforts to mitigate climate change </h2>



Protecting the Amazon’s integrity is not just a regional issue but a global necessity. As the Amazon continues to lose its ability to act as a carbon sink, efforts to mitigate climate change could face serious setbacks. 



Without immediate intervention, the degradation of this invaluable ecosystem could accelerate, pushing the world closer to climate tipping points.



In light of these new insights into the hidden drivers of carbon emissions, scientists and policymakers are calling for a more comprehensive approach to Amazon rainforest conservation. 



Efforts must move beyond simply preventing clear-cutting and should address forest degradation caused by smaller-scale but equally destructive activities. 



Integrating advanced technologies like LiDAR into conservation strategies will be vital in monitoring and managing forest health. 



Local communities, governments, and international organizations must collaborate to enforce stricter logging regulations, prevent wildfires, and restore degraded areas to safeguard the Amazon’s ecological and carbon-regulating functions.

Hidden triggers of Amazon carbon emissions revealed

In an astounding revelation, scientists have shed new light on...

It is a well-established fact that the ozone layer shields our planet from harmful ultraviolet radiation, playing a vital role in protecting life on Earth. 



Preserving this layer stands as a golden feather in the environmental preservation cap, representing one of humanity’s greatest successes in global environmental cooperation.



However, when ozone managed to take residence at the ground level, it ceased to be a silent guardian; it became a dangerous threat to both the environment and public health.



<h2 class="wp-block-heading" id="h-impacts-of-ground-level-ozone">Impacts of ground-level ozone </h2>



Ground-level ozone is a harmful combination of pollutants emitted from human activities such as industrial processes, vehicle emissions, and deforestation. 



Under the unforgiving glare of sunlight, ozone pollution is causing considerable disturbance to our ecosystems.



Not only does it pose serious health risks to humans, leading to respiratory and cardiovascular problems, but it also interferes with plants' ability to absorb carbon dioxide, undermining their role in mitigating climate change.



<h2 class="wp-block-heading" id="h-ozone-and-stunted-forest-growth">Ozone and stunted forest growth</h2>



New research published in the journal Nature Geoscience paints an alarming picture of the growing threat posed by ground-level <a href="https://www.earth.com/news/ozone-pollution-may-endanger-millions-by-2050/" target="_blank" rel="noreferrer noopener">ozone pollution</a>. It is significantly stunting the annual growth of tropical forests, with an average reduction of 5.1% in new growth.



The situation is even more severe in Asia, where certain regions are experiencing a dramatic 10.9% decline in new forest growth, highlighting the unequal impact of ozone pollution across the globe.



<h2 class="wp-block-heading" id="h-reduction-in-forest-carbon-storage">Reduction in forest carbon storage </h2>



According to Dr. Alexander Cheesman from <a href="https://www.jcu.edu.au/" target="_blank" rel="noreferrer noopener">James Cook University</a> and the <a href="https://www.exeter.ac.uk/" target="_blank" rel="noreferrer noopener">University of Exeter</a>, tropical forests play a crucial role in offsetting carbon dioxide emissions. "Our study shows that air pollution can jeopardize this critical ecosystem service."



The study estimates that ozone pollution has prevented the capture of a staggering 290 million tons of carbon annually since 2000.



This significant loss of <a href="https://www.earth.com/news/global-carbon-dioxide-emissions-hit-a-record-high-in-2023/" target="_blank" rel="noreferrer noopener">carbon</a> sequestration capacity underscores the detrimental effect ozone pollution is having on tropical forests, which are critical for absorbing excess atmospheric carbon and mitigating the impacts of climate change.



"The resulting cumulative loss equates to a 17% reduction in carbon removal by tropical forests so far this century," said Dr. Cheesman.



<h2 class="wp-block-heading" id="h-ozone-pollution-and-forest-restoration-efforts">Ozone pollution and forest restoration efforts</h2>



Urbanization, industrialization, and increased burning of <a href="https://www.earth.com/news/air-pollution-from-fossil-fuels-kills-5-million-people-each-year/" target="_blank" rel="noreferrer noopener">fossil fuels</a> have escalated emissions of "precursor" molecules, such as nitrogen oxides, that lead to ozone formation. 



"Ozone concentrations across the tropics are projected to rise further due to increased precursor emissions and altered atmospheric chemistry in a warming world," said Dr. Flossie Brown, co-lead author of the study.



These rising ozone levels pose a significant threat to current and future forest restoration efforts, particularly in areas critical to mitigating climate change. 



<h2 class="wp-block-heading" id="h-improving-air-quality">Improving air quality</h2>



"We found that areas of current and future forest restoration are disproportionately affected by this elevated ozone. It is clear that <a href="https://www.earth.com/news/trees-and-bushes-near-highways-improve-air-quality/" target="_blank" rel="noreferrer noopener">air quality</a> will continue to play an important but often overlooked part in the way forests absorb and store carbon," said Dr. Brown. 



Improving air quality is vital for enabling forests to effectively absorb and store carbon, noted study co-author Professor Stephen Sitch.



"Embracing a future with greater environmental protection would lead to reduced ground-level ozone, improved air quality, and the additional benefit of enhanced carbon uptake in tropical forests," said Professor Stitch.



<h2 class="wp-block-heading" id="h-the-dual-nature-of-ozone">The dual nature of ozone</h2>



Ozone exists in two forms: one as a protective shield in the stratosphere and the other as a harmful pollutant at ground level. 



While stratospheric ozone is essential for blocking harmful ultraviolet radiation, ground-level ozone (also known as tropospheric ozone) forms when pollutants from vehicles, industrial activities, and fires react with sunlight.



This ground-level ozone acts as a <a href="https://www.earth.com/news/greenhouse-gas-emissions-reach-another-all-time-high/" target="_blank" rel="noreferrer noopener">greenhouse gas</a>, trapping heat and contributing to climate change.



Ozone pollution is not only a threat to tropical forests but also to a wide range of ecosystems. In addition to stunting forest growth, ozone can damage crops, reduce agricultural productivity, and affect water quality by altering plant and soil interactions.



The broader ecological consequences of ozone pollution are becoming clearer, signaling an urgent need for stricter air quality regulations and the reduction of emissions that lead to its formation. 



The study is published in the journal <a href="https://dx.doi.org/10.1038/s41561-024-01530-1" target="_blank" rel="noreferrer noopener">Nature Geoscience</a>.

Ozone pollution is stunting tropical forest growth

It is a well-established fact that the ozone layer shields...

Have you ever paused to consider the hidden world of insect communication? For over 30 years, a scientist named Rex Cocroft has dedicated his career to understanding this fascinating arena. 



With a background in music and biology, Cocroft's work has been recognized across the globe, earning him a feature in a BBC documentary series and even inspiring fellow researchers to name a new species of treehoppers, Cladonota rex, in his honor.



<h2 class="wp-block-heading" id="h-treehoppers-communicate-using-vibrations">Treehoppers communicate using vibrations</h2>



Treehoppers are tiny insects that inhabit every continent except Antarctica. These <a href="https://www.earth.com/news/insects-boost-plant-evolution-in-surprising-ways/" target="_blank" rel="noreferrer noopener">small creatures</a> have advanced communication systems that are as intriguing as they are mysterious. 



The insects communicate by sending vibrations through a plant’s leaves and stem, almost like a silent symphony that humans cannot detect.



<h2 class="wp-block-heading" id="h-sending-messages-through-vibrations">Sending messages through vibrations</h2>



"Treehoppers have vibration sensors that detect when their legs move up and down, and they are extremely sensitive to that kind of motion," explained Cocroft, who is a biologist at the <a href="https://missouri.edu" target="_blank" rel="noreferrer noopener">University of Missouri</a>.



These vibrations work much like our sense of sound, allowing treehoppers to convey messages and signals. But remember, what we perceive as silence, is a robust conversation for treehoppers.



Cocroft uses unique sensors that function like guitar amplifiers. "Piezoelectric materials produce an electrical current when under mechanical stress," he noted. 



So, by using a piezo disk, the vibrations become an electrical signal that can be amplified, allowing him to tune into the chat between the bugs.



<h2 class="wp-block-heading" id="h-treehoppers-diverse-way-of-communicating">Treehoppers' diverse way of communicating</h2>



Treehoppers <a href="https://www.earth.com/news/plants-have-complex-biochemical-communication-networks/" target="_blank" rel="noreferrer noopener">communicate</a> by vibrating different parts of their bodies, which transmits vibrations via their legs to the plant stem. 



Interestingly, these creatures can also mimic cicadas by creating a clicking sound, and some can even create song-like sounds that vary in pitch, tone, and volume.



"Treehoppers typically have several different types of signals in their repertoire, and they are good at distinguishing between those and responding appropriately," explained Cocroft. It might not be what we usually associate with <a href="https://www.earth.com/news/beneficial-insects-are-severely-impacted-by-air-pollution/" target="_blank" rel="noreferrer noopener">insect</a> sounds, but the mechanics of producing and transmitting these sounds are unique.



"With more than 3,000 species of treehoppers worldwide, every species has different songs, so you don’t know what you’re going to hear until you begin to listen," said Cocroft.



<h2 class="wp-block-heading" id="h-musician-turned-biologist">Musician turned biologist</h2>



Having been drawn to the piano during his high school days, Cocroft initially pursued a degree in music in college. 



But the call of biology, a childhood passion, was too strong for him to ignore. After a stint as a research assistant at the Smithsonian National Museum of Natural History, Cocroft's interest in animal communication took flight, a journey that led him to the fascinating world of treehoppers. 



"Communication is such a key part of the behavior of any animal,” said Cocroft, who embodies a unique blend of passion, curiosity, and dedication.



<h2 class="wp-block-heading" id="h-communication-for-survival">Communication for survival</h2>



One might wonder, what evolutionary advantage does such complex communication provide to treehoppers? These small insects are not just engaging in idle chatter; their communication is essential for survival and reproduction. 



Through vibrational signals, treehoppers can relay alarms about potential predators, coordinate collective movements, and even engage in mating duets, where males and females signal back and forth to evaluate compatibility. 



Such intricate layers of communication have likely evolved to ensure that treehoppers can efficiently interact with their environment and make adaptive decisions critical for their biodiversity. 



<h2 class="wp-block-heading" id="h-secrets-of-insect-communication">Secrets of insect communication</h2>



Reflecting on decades of research, Cocroft is optimistic about the future of studying insect communication. 



With advancing technology, researchers are poised to uncover even more secrets about how treehoppers and other insects communicate. 



Innovations in sensor technology and computational analysis promise to deepen the understanding of vibrational ecology and its implications across <a href="https://www.earth.com/news/world-wildlife-day-using-technology-to-protect-our-natural-world/" target="_blank" rel="noreferrer noopener">ecosystems</a>. 



Cocroft envisions a future where these insights could impact agriculture, conservation, and even robotics, by emulating the efficient communication systems found in nature. 



"We are just scratching the surface of what these tiny creatures can teach us about communication and adaptation."



<h2 class="wp-block-heading" id="h-subtle-sounds-of-treehoppers">Subtle sounds of treehoppers </h2>



As we appreciate the subtle sounds of treehoppers, we witness the <a href="https://www.earth.com/news/nighttime-buzz-insect-activity-increases-by-31-4-at-night/" target="_blank" rel="noreferrer noopener">boundless wonders</a> that nature has to offer.



For over 30 years, Cocroft has studied these insects and their unique communication strategies, bringing closer to us a world that's often overlooked. 



And even as we marvel at these discoveries, it's clear that there's still much left to be understood. "I’ve always liked the exploration side of natural history, and there’s a lot we can still discover about how insects like treehoppers communicate," said Cocroft.

Treehoppers secretly communicate by making plants vibrate

Have you ever paused to consider the hidden world of...

Global methane emissions have continued to rise at an alarming rate despite international efforts to curb them.&nbsp;



More than 150 countries have pledged to reduce methane emissions by 30% by the end of this decade, yet new research reveals that in the past five years, methane emissions have surged faster than ever before.



In a perspective article published on September 10 in <a href="https://doi.org/10.1088/1748-9326/ad6463" target="_blank" rel="noreferrer noopener">Environmental Research Letters</a>, alongside data in Earth System Science Data, researchers warned that the current trend “cannot continue if we are to maintain a habitable climate.”&nbsp;



Both papers were part of the <a href="https://www.globalcarbonproject.org/" target="_blank" rel="noreferrer noopener">Global Carbon Project</a>, led by <a href="https://www.stanford.edu/" target="_blank" rel="noreferrer noopener">Stanford University</a> scientist Rob Jackson, which tracks global greenhouse gas emissions.



<h2 class="wp-block-heading" id="h-extreme-trajectory-of-rising-methane-rates-nbsp">Extreme trajectory of rising methane rates&nbsp;</h2>



The data reveals that atmospheric methane levels are now more than 2.6 times higher than pre-industrial levels, marking the highest concentration in at least 800,000 years.&nbsp;



Methane <a href="https://www.earth.com/news/methane-emissions-are-greatly-underestimated-by-the-epa/" target="_blank" rel="noreferrer noopener">emission rates</a> are currently rising along the most extreme trajectory predicted by climate scientists. This trend could lead to global warming of more than 3 degrees Celsius (5 degrees Fahrenheit) by the end of the century.&nbsp;



“Right now, the goals of the Global Methane Pledge seem as distant as a desert oasis,” said Jackson, who is the Michelle and Kevin Douglas Provostial Professor at Stanford's Doerr School of Sustainability. “We all hope they aren’t a mirage.”



<h2 class="wp-block-heading" id="h-spike-in-methane-emission-rates">Spike in methane emission rates</h2>



Methane, though short-lived compared to carbon dioxide, is a potent greenhouse gas. During its first 20 years in the atmosphere, methane traps heat nearly 90 times more effectively than carbon dioxide, making it a critical target in efforts to limit global warming.&nbsp;



However, despite increased attention on methane reduction, total emissions have surged by 61 million tons - or about 20% - over the past two decades.&nbsp;



This spike has been primarily driven by increases in coal mining, oil and gas production, livestock farming, and decomposing organic waste in <a href="https://www.earth.com/news/landfills-emit-exorbitant-amount-methane-into-atmosphere/" target="_blank" rel="noreferrer noopener">landfills</a>.



<h2 class="wp-block-heading" id="h-regional-disparities-in-methane-emissions-nbsp">Regional disparities in methane emissions&nbsp;</h2>



Marielle Saunois of <a href="https://www.universite-paris-saclay.fr/en/" target="_blank" rel="noreferrer noopener">Université Paris-Saclay</a>, lead author of the Earth System Science Data paper, emphasized the regional disparities in methane emissions.



“Only the European Union and possibly Australia appear to have decreased methane emissions from human activities over the past two decades. The largest regional increases have come from China and southeast Asia.”&nbsp;



<h2 class="wp-block-heading" id="h-methane-from-human-activities-nbsp">Methane from human activities&nbsp;</h2>



In 2020, the most recent year for complete data, around 400 million tons - or 65% - of global methane emissions were linked to human activities.&nbsp;



<a href="https://www.earth.com/news/agriculture-higher-methane-emissions/" target="_blank" rel="noreferrer noopener">Agriculture</a> and waste management together contributed two-thirds of these emissions, while the fossil fuel industry was responsible for the remainder. The researchers found that methane emissions from human sources have continued to rise through at least 2023.



<h2 class="wp-block-heading" id="h-reduced-emissions-of-nitrogen-oxides">Reduced emissions of nitrogen oxides</h2>



A particularly sharp increase in atmospheric methane was recorded in 2020, with 42 million tons added - double the average annual increase during the 2010s and more than six times the increase seen during the early 2000s.&nbsp;



Pandemic lockdowns in 2020 temporarily reduced emissions of nitrogen oxides (NOx), pollutants that typically degrade methane in the atmosphere. This reduction in NOx emissions contributed to the methane buildup.&nbsp;



“We’re still trying to understand the full effects of <a href="https://www.earth.com/news/covid-lockdowns-had-unexpected-impacts-on-wildlife-behavior/" target="_blank" rel="noreferrer noopener">COVID lockdowns</a> on the global methane budget,” Jackson explained. “COVID changed nearly everything - from fossil fuel use to emissions of other gasses that alter the lifetime of methane in the atmosphere.”



<h2 class="wp-block-heading" id="h-growing-influence-of-humans-on-methane-rates">Growing influence of humans on methane rates</h2>



In their most recent assessment, Global Carbon Project scientists revised how they classify methane sources.&nbsp;



Previously, all methane from wetlands, lakes, and rivers was considered natural. However, the latest methane budget accounts for the growing influence of human activities on these emissions.&nbsp;



For example, human-made reservoirs contribute an estimated 30 million tons of methane annually, as submerged organic material decays and releases the gas.&nbsp;



“Emissions from reservoirs behind dams are as much a direct human source as methane emissions from a cow or an oil and gas field,” noted Jackson.



<h2 class="wp-block-heading" id="h-threat-to-global-climate-goals-nbsp">Threat to global climate goals&nbsp;</h2>



The researchers estimate that about one-third of methane emissions from wetlands and freshwater sources in recent years have been influenced by human factors, such as agricultural runoff, wastewater, land use changes, and rising temperatures.



The continued rise in methane emissions poses a significant threat to global climate goals. As extreme weather events and heat waves become more frequent, the consequences of this trend are becoming increasingly clear.&nbsp;



“The world has reached the threshold of 1.5C increases in global average surface temperature, and is only beginning to experience the full consequences,” noted the study authors.



<h2 class="wp-block-heading" id="h-urgent-action-is-needed">Urgent action is needed </h2>



Addressing this challenge will require global efforts to reduce methane emissions at their source. This includes implementing measures such as leak detection in the fossil fuel industry, improved waste management, and changes in <a href="https://www.earth.com/news/satellites-detect-methane-emission-from-cow-burps/" target="_blank" rel="noreferrer noopener">livestock</a> farming practices.&nbsp;



Without urgent and concerted action, methane emissions will continue to drive global temperatures beyond critical thresholds, threatening the planet's habitability.

Rising methane emissions threaten Earth's habitability

Global methane emissions have continued to rise at an alarming...

Warm waters in the Atlantic Ocean and the Gulf of Mexico can power massive hurricanes. However, the level of destructiveness of such hurricanes does not depend only on the climate, but also on the people and properties that are in harm's way.&nbsp;



For instance, in various coastal cities, fast population growth has left an increasing number of people inhabiting areas at high risk of flooding.



<h2 class="wp-block-heading" id="h-socially-vulnerable-communities-nbsp">Socially vulnerable communities&nbsp;</h2>



Wanyun Shao, an associate professor of geography at the <a href="https://www.ua.edu/" target="_blank" rel="noreferrer noopener">University of Alabama</a>, studies precisely this human dimension of climate change and related <a href="https://www.earth.com/news/global-risk-natural-disasters-doubled/" target="_blank" rel="noreferrer noopener">natural disasters</a>.&nbsp;



Her research shows that socially vulnerable communities - which are least capable of preparing for disasters or recovering afterward - are usually concentrated in regions which are more susceptible to flooding, especially on the Gulf Coast.



<h2 class="wp-block-heading" id="h-coastal-populations-nbsp-exposed-to-hurricanes">Coastal populations&nbsp;exposed to hurricanes </h2>



Nowadays, almost 40% of the U.S. population lives in coastal areas, many of which are increasingly exposed to hurricanes and high tide flooding that have been worsened by sea level rise.



Particularly, the Gulf of Mexico is prone to multiple climate change-induced severe weather events. For instance, when Hurricane Beryl hit Texas in July 2024 and caused heavy rain and flooding, three million homes and businesses lost power for several days - at the same time when they were exposed to an intense heat wave.&nbsp;



Furthermore, over one-fifth of the population in Harris County (home to Houston), is socially vulnerable, so they are more susceptible to harm from extreme weather.



<h2 class="wp-block-heading" id="h-vulnerable-cities-on-the-gulf-coast-nbsp">Vulnerable cities on the Gulf Coast&nbsp;</h2>



Socially vulnerable populations include the elderly, persons with disabilities, people living in <a href="https://www.earth.com/news/satellite-imagery-used-to-map-global-poverty/" target="_blank" rel="noreferrer noopener">poverty</a>, and mobile home dwellers. These people don't have the necessary resources or physical ability to prepare for storms, or the means to rebuild their homes in the wake of such natural disasters.



Many cities along the Gulf Coast, including Houston, New Orleans, Mobile, Alabama, and Tampa, Florida, have large socially vulnerable populations. In addition, in some of these cities, land development and political decisions have increased the risks posed by hurricanes.



<h2 class="wp-block-heading" id="h-extreme-challenges-from-urban-sprawl-nbsp">Extreme challenges from urban sprawl&nbsp;</h2>



Houston is a clear case study that shows the extreme challenges arising from unbridled urban sprawl in coastal cities, particularly those most threatened by hurricanes.



From 2000 to 2023, Harris County grew by one-third, adding 1.3 million residents. While the economic boom related to <a href="https://www.earth.com/news/global-population-10-9-billion/" target="_blank" rel="noreferrer noopener">population growth</a> brought new jobs to the county, many of these jobs do not pay well, making Harris County's poverty rate 16.5% (compared to the national average of 11.5%).



After Hurricane Harvey's massive flood damage in 2017, a heated debate started. Many people pointed out a problematic reality - Houston was built on a swamp.&nbsp;



In these conditions, the laissez-faire mentality of Texas politics, which prioritizes not intervening in population growth, has contributed to unbridled urban development, turning what once was a wetland to concrete land. Thus, with wetlands just paved over, heavy rain cannot be easily absorbed, making new neighborhoods highly vulnerable to flooding.



<h2 class="wp-block-heading" id="h-urgent-need-to-rethink-urban-development-nbsp">Urgent need to rethink urban development&nbsp;</h2>



Previous research by Shao’s research group that focused on risk decision-making has found that, among all land use and land cover types in the county, developed land has increased fastest, from 35% of the county's land in 2000 to 50% in 2020.



Hurricane Harvey provided a good example of the importance of planning for extreme weather events in urban development. Unfortunately, as the hurricane’s devastation fades in the collective memory, increasingly more people are now moving to Houston.



According to Shao and her colleagues, coastal communities cannot afford to wait for a natural disaster's wake-up call to start investing in protecting themselves. To prepare for future such disasters, they must urgently rethink urban development, while keeping the realities of climate change in mind.



<h2 class="wp-block-heading" id="h-hurricane-resilience-in-coastal-cities">Hurricane resilience in coastal cities</h2>



Building resilience involves strengthening flood control systems and upgrading emergency response strategies to account for increasingly severe <a href="https://www.earth.com/news/coastal-hurricanes-are-intensifying-faster-due-to-climate-change/" target="_blank" rel="noreferrer noopener">storms</a>. This also requires implementing zoning regulations that restrict construction in high-risk flood zones.&nbsp;



In some cases, it may even be necessary to consider managed retreat, where buyouts are used to relocate vulnerable communities to safer areas.



Raising public awareness is equally crucial. Educational campaigns can inform people about disaster risks, while accurate <a href="https://www.earth.com/news/can-we-outrun-the-flood-risks-of-climate-change/" target="_blank" rel="noreferrer noopener">flood</a> risk maps can encourage individuals to purchase insurance, select safer locations, and better safeguard their homes against local hazards.&nbsp;



Effective awareness efforts often collaborate with grassroots organizations to expand their reach, ensuring that vulnerable populations are informed and prepared.

Imagine having a crystal ball that could predict the next volcanic eruption. For millions of people living near active volcanoes, such a tool would be invaluable. 



Interestingly, some crystals formed deep within the Earth can indeed help forecast volcanic activity. These crystals, which are created as molten rock travels from beneath the Earth's surface, hold vital clues about past eruptions.



<h2 class="wp-block-heading" id="h-crystals-hold-a-record-of-eruptions-nbsp">Crystals hold a record of eruptions&nbsp;</h2>



By employing advanced scientific methods, researchers can extract a hidden record from these <a href="https://www.earth.com/news/stars-turning-crystals/" target="_blank" rel="noreferrer noopener">crystals</a>, uncovering the reasons, locations, and timings of previous eruptions. This historical information can help interpret early signs of volcanic unrest, such as earthquakes, which often signal magma moving toward the surface.&nbsp;



In a new column in <a href="https://www.nature.com/articles/s41561-024-01509-y" target="_blank" rel="noreferrer noopener">Nature Geoscience</a>, Teresa Ubide, a geoscientist at the <a href="https://www.uq.edu.au/" target="_blank" rel="noreferrer noopener">University of Queensland</a>, discusses how we are getting closer to having crystal balls - at least for volcanoes.



<h2 class="wp-block-heading" id="h-crystals-formed-by-cooling-magma">Crystals formed by cooling magma</h2>



When <a href="https://www.earth.com/news/volcanic-magma-traced-to-melting-in-earths-crust/" target="_blank" rel="noreferrer noopener">magma</a>, the extremely hot molten rock that powers eruptions, forms tens of kilometers below Earth's surface in the mantle, it begins a complex journey upward.&nbsp;



During this trip, magma may pause in reservoirs and travel through a winding path before eventually erupting. As magma ascends, it cools, forming small crystals that can be carried to the surface during eruptions.



Once magma reaches the surface, it can either flow as lava or explode into fragmented particles known as pyroclasts. As these materials cool, they solidify into volcanic rocks, which preserve the crystals formed deep within the Earth. These crystals serve as “crystal balls,” preserving the memory of everything they experienced inside the volcano.



<h2 class="wp-block-heading" id="h-distinct-appearance-of-volcanic-crystals">Distinct appearance of volcanic crystals</h2>



The appearance of these crystals depends on their mineral composition. For instance, the green olivine found in Hawaiian lavas and the white plagioclase crystals in the Tweed volcano's lavas on the Queensland-New South Wales border are distinct examples.&nbsp;



However, one of the most critical minerals for studying volcanoes is clinopyroxene. This mineral produces shiny black crystals that hold essential information about the inner workings of volcanoes.



<h2 class="wp-block-heading" id="h-chemical-changes-within-the-crystals-nbsp">Chemical changes within the crystals&nbsp;</h2>



Clinopyroxene crystals may be as tiny as a grain of sand, but under a microscope, they reveal extraordinary details about volcanic activity. They grow in concentric zones, similar to <a href="https://www.earth.com/news/earths-largest-ever-solar-storm-discovered-through-tree-rings/" target="_blank" rel="noreferrer noopener">tree rings</a>, with each zone documenting changes in the magma environment within the volcano.&nbsp;



The outermost growth zone is particularly important, as it can indicate if an eruption was triggered by fresh magma rising from deep within the Earth.&nbsp;



By analyzing the chemical changes within these crystals, scientists can estimate how long it took for magma to reach the surface - information that could help predict future eruptions.



<h2 class="wp-block-heading" id="h-indications-of-potential-volcanic-eruptions">Indications of potential volcanic eruptions</h2>



These crystals sometimes grow with different compositions in various directions, a phenomenon called sector zoning, which resembles an hourglass inside the crystal.&nbsp;



Sector zoning provides further clues, suggesting that the magma underwent complex processes such as mixing with other magma, releasing gas, or rising quickly before an eruption.&nbsp;



By identifying these processes in the crystals, volcanologists can watch for similar signs at the surface, offering early indications of potential volcanic activity.



It’s also critical to identify where within the volcano these eruption triggers occur. This information can help determine if certain depths, where earthquakes or ground deformations occur, are particularly significant for <a href="https://www.earth.com/news/new-research-enhances-predictions-on-volcanic-eruptions/" target="_blank" rel="noreferrer noopener">predicting an eruption</a>.



<h2 class="wp-block-heading" id="h-pressure-conditions-during-crystal-formation-nbsp">Pressure conditions during crystal formation&nbsp;</h2>



The chemical makeup of clinopyroxene crystals also provides clues about the pressure conditions during their formation, which can be translated into the depth of magma storage below the surface.&nbsp;



Analyzing these chemical variations requires cutting-edge laboratory techniques, such as using lasers the width of a human hair or focusing intense synchrotron light from particle accelerators like the one in Melbourne, Australia.&nbsp;



These tools enable scientists to extract detailed information about the magma’s journey from the microscopic structures of the crystals.



Next time you hike near a volcano, whether it's in Hawai'i, Iceland, or the Glass House Mountains in Australia, look closely at the rocks for colorful specks. These tiny crystals are the keys to unlocking the history of the volcano - and they might also offer insights into its future.

Crystals can help predict volcanic eruptions

Imagine having a crystal ball that could predict the next...

The world is racing against time, rapidly devouring resources that sustain life, and if we continue on our current trajectory, even basic living standards might become a luxury. But, there's hope for the Earth and its resources. 



A recent report suggests that we have the power to change the tide, provided we transform our economic systems and technologies, and adopt a more equitable resource management approach.



<h2 class="wp-block-heading" id="h-green-light-for-cities-and-businesses">Green light for cities and businesses</h2>



The research, conducted by an international team of scientists including those from The Australian National University (<a href="https://www.anu.edu.au" target="_blank" rel="noreferrer noopener">ANU</a>), makes a compelling case for cities and businesses to step up. 



The report, published in The Lancet Planetary Health, urges them to adopt the mantle of “stewards” of Earth’s critical resources. 



By demonstrating how to reduce their environmental impact, cities and businesses could play a vital role in <a href="https://www.earth.com/news/earth-day-2024-the-tide-may-finally-be-turning/" target="_blank" rel="noreferrer noopener">protecting the planet</a>.



<h2 class="wp-block-heading" id="h-protecting-earth-s-resources">Protecting Earth's resources</h2>



The research, a product of the Earth Commission's first phase, involved more than 40 researchers from various disciplines worldwide. 



<a href="https://earthcommission.org/" target="_blank" rel="noreferrer noopener">The Earth Commission</a>, founded in 2019, includes 18 globally respected scholars who provide interdisciplinary insights.



The report leans heavily on the findings of the Safe and Just Earth System Boundaries report published in <a href="https://www.nature.com/articles/s41586-023-06083-8" target="_blank" rel="noreferrer noopener">Nature</a> last year. 



This report unveiled a disturbing fact -- humanity has overstepped most of the crucial boundaries within which people and the planet can flourish.



<h2 class="wp-block-heading" id="h-driving-change-in-earth-s-resources">Driving change in Earth's resources</h2>



Distinguished Professor Xuemei Bai from ANU, one of the three lead authors who led the working group on Translation, emphasized the pivotal role of companies and cities. 



According to her, these entities possess the necessary resources to effect sweeping changes and significantly lessen the strains on <a href="https://www.earth.com/news/world-environment-day-2024-a-call-for-land-restoration/" target="_blank" rel="noreferrer noopener">our planet</a>.



"Companies and cities have a huge potential to make a difference, especially if they work towards the same goal, which is to ensure the <a href="https://www.earth.com/news/climate-records-shatter-2024-set-to-be-hottest-year-ever/" target="_blank" rel="noreferrer noopener">planet</a> can provide for everyone long-term," Professor Bai points out. 



She added that they are more adaptable than states and can set science-based goals that align with the research findings.



Her colleague, Professor Stuart Bunn from <a href="https://www.griffith.edu.au" target="_blank" rel="noreferrer noopener">Griffith University</a>, echoed her sentiments. He co-led a working group focusing on freshwater and nutrient pollution boundaries, another critical aspect of Earth's sustainability.



<h2 class="wp-block-heading" id="h-challenge-of-our-lifetime">Challenge of our lifetime</h2>



The research confirmed that our planet's resilience is under immense strain. However, it emphasized that it's still possible for humans to avoid the adverse effects of Earth's system change if we act urgently.



The way forward? Reducing inequalities in accessing and using critical resources like freshwater and nutrients. 



Alongside this, there needs to be fair sharing of responsibilities such as carbon emission reduction, combined with an economic and technological overhaul.



Without urgent transformations, the report warns that by 2050, <a href="https://www.earth.com/news/earth-just-experienced-its-hottest-day-ever/" target="_blank" rel="noreferrer noopener">Earth's climate</a> could deteriorate so much that there would be no "safe and just space" left.



<h2 class="wp-block-heading" id="h-sustainability-and-earth-s-resources">Sustainability and Earth's resources</h2>



Innovation stands as a cornerstone in the pursuit of sustainability, offering solutions that can bridge the gap between consumption and conservation. 



By harnessing advancements in technology, such as renewable energy, smart agriculture, and sustainable manufacturing practices, we can significantly reduce our ecological footprint. 



Universities, research institutions, and private companies are increasingly collaborating to develop cutting-edge solutions that not only address immediate environmental concerns but also create systems that can adapt to future challenges. 



This interconnected web of innovation empowers communities and industries to meet their needs while safeguarding our planet's resources for generations to come.



<h2 class="wp-block-heading" id="h-path-to-a-safe-and-just-space">Path to a "safe and just space"</h2>



To prevent this potential catastrophe, the researchers recommend a series of critical actions to save the Earth's resources. 



Primarily, policymakers, businesses, civil society, and communities need to collaborate to transform our economic system with policies and funding mechanisms that address inequality while reducing pressure on <a href="https://www.earth.com/news/earth-days-getting-longer-rotation-slows-climate-change/" target="_blank" rel="noreferrer noopener">nature and climate</a>.



Secondly, efficient and effective management, sharing, and usage of resources at all societal levels are fundamental. 



This includes tackling excessive consumption in some communities, which denies access to vital resources for the most needy.



Thirdly, investing in sustainable and affordable technologies that allow us to reduce resource usage is paramount in reopening the "safe and just space."



Here's the bottom line: sure, we're in deep water, but we're not drowning yet. This report is a lifeline, a blueprint for change, and a call to action. 



As daunting as the challenge might seem, we have the resources, the knowledge, and yes, the responsibility, to turn things around.



The report is published in the journal <a href="https://www.thelancet.com/journals/lanplh/article/PIIS2542-5196(24)00042-1/fulltext" target="_blank" rel="noreferrer noopener">The Lancet Planetary Health</a>.

How cities and businesses can help save Earth and its resources

The world is racing against time, rapidly devouring resources that...

Air samples collected at altitudes up to 2,000 miles above Japan held an astonishing variety of living microbes, such as bacteria and fungi, many of which are toxic to humans.



Not just the homegrown ones either. Some of these microbial stowaways traveled over 1,000 miles with the help of aerosols, originating from regions lush with fertilizers and pesticides.



This has launched the scientific world into a wave of questions about the journey of human, animal, and plant pathogens across vast geographical terrains, invisible to the naked eye. 



Leading this microbial exploration was the Barcelona Institute for Global Health (<a href="https://www.isglobal.org/en/" target="_blank" rel="noreferrer noopener">ISGlobal</a>) with support from the Daniel Bravo Andreu Private Foundation (<a href="https://www.fundaciodanielbravo.org/en/" target="_blank" rel="noreferrer noopener">FPDBA</a>).



<h2 class="wp-block-heading" id="h-microbes-travel-in-the-air">Microbes travel in the air</h2>



<a href="https://www.earth.com/news/microbes-laid-the-foundation-for-early-life-on-earth/" target="_blank" rel="noreferrer noopener">Pathogens</a> hitching a ride on the wind isn’t unheard of. But the diversity of microbes that can survive at high altitudes, where conditions could give even an Everest mountaineer pause, is a fresh revelation.



“We know that above a certain point in the troposphere (called the planetary boundary layer), certain materials can be transported over long distances because the air in that region is isolated from the surface and there is less friction. But we did not suspect that viable microorganisms could be there also,” says&nbsp;Xavier Rodó, ICREA researcher at ISGlobal.



Rodó and his team carried out ten tropospheric flights to examine microbial diversity at high altitudes -- a significant jump from studies usually executed just a few meters above the ground or the ocean.



<h2 class="wp-block-heading" id="h-tracing-the-microbial-travel-path">Tracing the microbial travel path</h2>



Rodó and his international team boarded a Cessna aircraft and conducted air surveys above Japan, tracing wind currents from mainland Asia. 



These <a href="https://www.earth.com/news/how-do-deadly-microbes-travel-around-the-world-so-quickly/" target="_blank" rel="noreferrer noopener">transcontinental airways</a>, known as tropospheric bridges, connect air from distant parts of the world.



For context, think about air that lifts in mainland China and then descends over Tokyo, courtesy of typical winter weather conditions. 



A total of 22 aerosol filter samples were gathered during two periods (in February and April 2014), methodically analyzed for their chemical and biological composition.



Sequencing DNA from the samples, the team identified over 266 fungal and 305 bacterial genera associated with the aerosols. 



<h2 class="wp-block-heading" id="h-types-of-microbes-in-the-air">Types of microbes in the air</h2>



This microbial soup included potential pathogens for humans, animals, and plants -- familiar names like Escherichia coli, Serratia marcescens, Haemophillus parainfluenzae, and several Staphylococcus species were among the bacterial mix.



The fungal factions included genera like Candida and Cladosporium, to name a couple.



“Surprisingly, the Micrococcus luteus strain isolated was resistant to multiple drugs, including carbapenems, glycopeptides, ciprofloxacin, and trimethoprim-sulfamethoxazole," says Sofya Podzniakova, co-first author of the study.



"Our findings suggest that antimicrobial resistance could spread over long distances via this previously unrecognized route", 



<h2 class="wp-block-heading" id="h-tropospheric-travel-tunnel-of-air-microbes">Tropospheric travel tunnel of air microbes</h2>



If you're curious about the origin of these airborne pathogens, the answer could be right underneath our noses -- or rather, our feet.



The presence of elements such as zinc sulfate and potassium, usually found in fertilizers and pesticides, implies an agricultural source. A scenario quite consistent with the extensively farmed croplands in northeast China.



The high-altitude and ground samples from the days examined showed a striking similarity in <a href="https://www.earth.com/news/marine-microbes-can-tell-us-about-global-changes-in-the-ocean/" target="_blank" rel="noreferrer noopener">microbial diversity</a>. A consequence of air descending from altitudes to the <a href="https://www.earth.com/news/microbes-activities-underground-revealed-by-new-technology/" target="_blank" rel="noreferrer noopener">ground</a>, perhaps? 



The particle transport models simulated by Roger Curcoll, currently a researcher at the Universitat Politècnica de Catalunya -- BarcelonaTech (<a href="https://www.upc.edu/en" target="_blank" rel="noreferrer noopener">UPC</a>), would certainly support this theory.



<h2 class="wp-block-heading" id="h-new-chapter-in-microbe-transport-study">New chapter in microbe transport study</h2>



The implications of this study are profoundly impactful. “Our findings uncover a rich and unprecedented diversity of microbes that are dispersed by wind currents thousands of kilometers away from their sources by intense tunnels of wind that form high in the troposphere,” Rodó emphasized.



“They represent a paradigm shift in our understanding of how human health can be affected by pathogens thriving in the environment, particularly in the air."



Though there's no direct trace yet linking the presence of known human <a href="https://www.earth.com/news/plant-pandemic-looms-as-pathogens-move-from-wild-plants-to-crops/" target="_blank" rel="noreferrer noopener">pathogens</a> in aerosols and health effects, the study affirms the pressing need for further exploration of air microbes and microbial pathogens' long-distance travel.



So, the next time you feel the wind against your face, remember, it has stories to tell -- tales of microbial hitchhikers scaling the heights of the troposphere and crossing continents. Globe-trotting pathogens show us how interconnected our world truly is, even in ways we can't see.



The study is published in the journal <a href="https://www.pnas.org/doi/10.1073/pnas.2404191121" target="_blank" rel="noreferrer noopener">Proceedings of the National Academy of Sciences</a>.

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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



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



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



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



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



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



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>.

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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

Today's Video of the Day from <a href="https://www.nasa.gov/goddard">NASA Goddard</a> describes how record-breaking heat expressed itself around the world in 2022.



Scientists have determined that 2022 was the 5th warmest year since 1880. Furthermore, the last nine consecutive years have been the warmest on record.



From devastating floods and wildfires to natural disasters like Hurricane Ian, 2022 showed us yet again how a warming climate affects people across the globe.&nbsp;



"As we look back at 20:22 and years past, we see that each year we better understand the challenges we face and how important it is to meet them," says NASA.

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



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



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



Images from Earth-observing satellites show how the world’s plant life is affected by natural disasters, fires, and deforestation. Satellites also reveal how widespread changes in vegetation impact waterways,&nbsp; the climate, air quality. Satellites communicate by using radio waves to send signals to the antennas on the Earth.

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."
