For years, scientists believed they had a decent handle on what was melting the ice in West Antarctica. Warmer oceans and stronger winds blowing in from the west - that was the popular theory.



But now, after running climate simulations using local data, researchers have discovered that we might have been looking the wrong way entirely. It’s not the westerly winds causing the biggest trouble - it’s the northerly winds.



<h2 class="wp-block-heading" id="h-ice-loss-means-rising-seas">Ice loss means rising seas</h2>



Antarctica holds most of the planet’s freshwater, frozen in a massive sheet of ice that covers an area bigger than the U.S. and Mexico combined. 



That ice isn’t just sitting still. Some of it flows slowly into the ocean, held back by giant floating extensions called <a href="https://www.earth.com/news/antarcticas-melting-ice-shelves-threaten-global-sea-levels/">ice shelves</a>. If the ice sheet in West Antarctica collapses, sea levels around the world could rise by as much as 20 feet.



Even small changes in how fast that ice melts can have huge consequences for coastal cities, global currents, and <a href="https://www.earth.com/news/ai-prediction-model-is-a-major-breakthrough-in-weather-forecasting/">weather systems</a>. 



That’s why scientists have spent decades trying to understand what’s causing the West Antarctic ice sheet to shrink. It’s been getting smaller since at least the 1940s. But not all the pieces of the puzzle were adding up.



<h2 class="wp-block-heading" id="h-tracking-antarctica-s-hidden-winds">Tracking Antarctica’s hidden winds</h2>



The new study was led by researchers at the <a href="https://www.washington.edu/" target="_blank" rel="noreferrer noopener">University of Washington</a> (UW). They weren’t satisfied with the usual <a href="https://www.earth.com/news/climate-models-underestimate-sea-ice-melt-and-global-warming/">climate models</a>, which often rely on global data and struggle with the lack of weather stations in Antarctica. So they decided to build something better.



They pulled in proxy data - long-term records preserved in things like ice cores, tree rings, and coral. These natural sources can give clues about past wind and weather patterns, helping fill in the gaps left by satellite data and on-the-ground observations.



“We thought that we were going to support what the climate models showed, which was that the westerly winds were getting stronger near the coast of Antarctica,” said Gemma O’Connor, lead author and a UW postdoctoral researcher. 



“But there was no evidence of westerly winds strengthening in this part of Antarctica.” That finding was odd. If westerly winds weren’t to blame, what was?



<h2 class="wp-block-heading" id="h-northerly-winds-drive-the-ice-melt">Northerly winds drive the ice melt</h2>



The team used high-resolution simulations to test 30 different wind scenarios. Each run of the model applied a different wind pattern to see what happened to the ice over a five-year stretch. They repeated the process again and again.



One pattern kept showing up: when winds came from the north, ice loss accelerated. <a href="https://www.earth.com/news/the-westerly-winds-are-changing-and-the-consequences-are-unknown/">Westerly winds</a> didn’t do much.



Northerly winds shifted sea ice, closing small open areas in the ice cover known as polynyas. These are basically patches where heat can escape from the ocean into the atmosphere. When the winds closed them off, the ocean held onto more of its heat.



“Sea ice is a really good insulator, it keeps the ocean relatively warm compared to the air,” said Kyle Armour, a UW professor. “When northerly winds close the polynyas, it reduces ocean heat loss, which means warmer waters and more melting of ice shelves below the surface.”



This hidden heating creates a chain reaction. As the warmer water melts the ice shelves from below, freshwater enters the salty sea. That mix causes a difference in density, which pulls even more warm ocean water into the region - speeding up the melt further.



<h2 class="wp-block-heading" id="h-a-climate-connection-we-didn-t-expect">A climate connection we didn’t expect</h2>



The big question is: what’s making those northerly winds stronger? Early signs point to climate change. 



Emissions of <a href="https://www.earth.com/news/greenhouse-gas-emissions-reach-another-all-time-high/">greenhouse gases</a> are likely decreasing air pressure over the Amundsen Sea, a region that shapes many of Antarctica’s weather patterns. Lower pressure strengthens the northerly winds - the same ones that are making the melt worse.



“This mechanism provides a connection between West Antarctic ice loss and human-induced climate change, albeit a different mechanism than we previously suspected,” O’Connor said.



This isn’t just a scientific curiosity. It’s a real link between our actions and the future of the world’s ice. If our emissions are playing a role in these winds, then reducing those emissions could slow the melting.



“We know the Earth is warming up on average, but that alone doesn’t explain ice loss in Antarctica,” said Eric Steig, professor of Earth and space sciences at UW. 



<h2 class="wp-block-heading" id="h-northerly-winds-change-the-story">Northerly winds change the story</h2>



For decades, the focus has been on <a href="https://www.earth.com/news/the-westerly-winds-are-changing-and-the-consequences-are-unknown/">westerly winds</a> - the ones that blow from west to east across the Southern Hemisphere. 



Scientists thought they were pushing warm ocean water toward Antarctica and driving the ice to melt faster. But they missed something important.



“I think what Gemma has done is going to lead to a complete revolution in the understanding of what drives Antarctic ice loss,” Armour said. “We had all sorts of theories about the winds that blow from west to east, but the northerly winds weren’t even on our radar. We were off by 90 degrees.”



The lesson here is clear. Climate science is constantly evolving, and even long-standing ideas can be turned on their head. In this case, or rather, on their side.



Understanding which way the wind is blowing - literally - might be one of the keys to protecting the future of Earth’s ice.

Antarctic ice melt traced to an overlooked source

For years, scientists believed they had a decent handle on what was melting the ice in West Antarctica. Warmer oceans and stronger winds blowing in from the west - that was the popular theory. But now, after running climate simulations using local data, researchers have discovered that we might have been looking the wrong way entirely.

Scientists at the <a href="https://www.southampton.ac.uk/" target="_blank" rel="noreferrer noopener">University of Southampton</a> have successfully engineered the microbiome of plants for the first time, marking a significant advancement in agricultural biotechnology. 



This development has the potential to revolutionize the way we protect <a href="https://www.earth.com/news/tackling-malnutrition-new-satellite-can-monitor-nutrients-in-crops-from-space/">crops</a> from diseases, substantially reducing the dependence on harmful pesticides.



<h2 class="wp-block-heading" id="h-plant-microbiomes">Plant microbiomes</h2>



The significance of the microbiome, which refers to a complex community of microorganisms, has been a subject of growing interest. In humans, gut microbiomes play a critical role in various aspects of health, from metabolism to immunity.&nbsp;



Similarly, plants host diverse microbiomes consisting of bacteria, fungi, viruses, and other microorganisms within their roots, stems, and leaves. These microbial communities are crucial in determining a plant's health and its susceptibility to diseases.



<h2 class="wp-block-heading" id="h-study-significance">Study significance</h2>



"In nature, plants and their associated microbes, collectively known as the microbiota, form functional entities that rely on each other. The microbiota contributes to aspects such as disease resistance, stress tolerance, and nutrient acquisition," wrote the study authors.



"Successful recruitment and maintenance of a sufficient abundance of specific microbial members determines the outcome of plant-microbiota interactions. Thus, understanding the principles driving microbiome assembly in crop plants has become one of the main pursuits of present studies in order to integrate microbiome functioning into sustainable crop production."



<h2 class="wp-block-heading" id="h-focus-of-the-research-nbsp">Focus of the research&nbsp;</h2>



The research was focused on a specific gene in the lignin biosynthesis cluster of the rice plant, a component crucial for plant cell walls and overall biomass.&nbsp;



Upon deactivating this gene, the scientists observed a decline in certain beneficial bacterial populations, underscoring the gene's role in shaping the plant's microbiome.&nbsp;



On the other hand, overexpressing the gene resulted in the increased production of a particular metabolite, subsequently enhancing the prevalence of beneficial bacteria.



<h2 class="wp-block-heading" id="h-successful-results">Successful results</h2>



The genetic modification proved its effectiveness when the engineered rice plants exhibited substantial resistance to Xanthomonas oryzae. This pathogen is responsible for bacterial blight, a prevalent and destructive disease in rice crops.&nbsp;



The traditional method of controlling bacterial blight involves the use of polluting pesticides. Therefore, the development of crops with a naturally protective microbiome could not only secure food production but also benefit the environment.



<h2 class="wp-block-heading" id="h-broader-implications-nbsp">Broader implications&nbsp;</h2>



“For the first time, we’ve been able to change the makeup of a plant’s microbiome in a targeted way, boosting the numbers of beneficial bacteria that can protect the plant from other, harmful bacteria,” said study co-author Dr. Tomislav Cernava.



“This breakthrough could reduce reliance on pesticides, which are harmful to the environment. We’ve achieved this in rice crops, but the framework we’ve created could be applied to other plants and unlock other opportunities to improve their microbiome. For example, microbes that increase nutrient provision to crops could reduce the need for synthetic fertilizers.”



The implications of this research extend beyond disease resistance. The Southampton team is exploring ways to manipulate plant microbiomes to enhance other aspects of plant health, such as nutrient provision.&nbsp;



The study is published in the journal <a href="http://dx.doi.org/10.1038/s41467-023-44335-3" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

Engineered plant microbiomes: The future of crop protection 

Scientists at the University of Southampton have successfully engineered the...

Scientists from the <a href="https://www.unsw.edu.au/" target="_blank" rel="noreferrer noopener">University of New South Wales</a> (UNSW) Sydney have developed a comprehensive plan to cool off one of the world’s hottest cities. The researchers outlined a strategy to lower the temperature of Riyadh, Saudi Arabia by as much as 4.5°C. 



<h2 class="wp-block-heading" id="h-reducing-extreme-heat-nbsp">Reducing extreme heat&nbsp;</h2>



In collaboration with the Royal Commission of Riyadh, the experts present a multi-faceted approach combining "super cool" building materials, expanded green spaces, and energy-efficient retrofitting to tackle extreme urban heat.



The study was led by Professor Mattheos Santamouris, who is renowned for his work in developing strategies to reduce urban heat. The research is especially relevant as over 450 cities struggle with extreme heat, exacerbating energy consumption and posing severe health risks.



“The project demonstrates the tremendous impact advanced heat mitigation technologies and techniques can have to reduce urban overheating, decrease cooling needs, and improve lives,” said Professor Santamouris.



<h2 class="wp-block-heading" id="h-urban-heat-island-nbsp">Urban heat island&nbsp;</h2>



Riyadh, the capital of Saudi Arabia, is a prime example of an urban heat island. Encircled by desert, the city often experiences <a href="https://www.earth.com/news/rising-temperatures-linked-to-vision-impairment/">temperatures</a> soaring above 50°C during summer months. 



Contributing factors include limited vegetation, heat-trapping conventional building materials like asphalt and concrete, and additional heat from vehicles and industrial activities. This scenario is further intensified by climate change and rapid urbanization.



The UNSW team conducted extensive simulations in Riyadh's Al Masiaf precinct, analyzing the energy performance of 3,323 urban buildings under eight different heat mitigation scenarios. These scenarios combined various super cool materials, vegetation types, and energy retrofitting levels to identify the most effective strategies for cooling the city and reducing its energy requirements.



<h2 class="wp-block-heading" id="h-pinpointing-the-optimal-approach-nbsp">Pinpointing the optimal approach&nbsp;</h2>



The simulations revealed that it's possible to lower outdoor temperatures by nearly 4.5°C during summer months, while also conserving up to 16% in cooling energy. The optimal approach for Riyadh includes the implementation of super cool materials on building roofs and more than doubling the number of irrigated trees to enhance transpiration cooling.



The study warns against the indiscriminate application of urban cooling techniques without detailed scientific optimization. For instance, using non-irrigated greenery could inadvertently increase the city's temperature.



“By implementing the right combination of advanced heat mitigation technologies and techniques, it is possible to decrease the ambient temperature at the precinct scale,” said Professor Santamouris. “For a sweltering city the size of Riyadh, significantly reducing cooling needs is also tremendous for sustainability.”



<h2 class="wp-block-heading" id="h-far-reaching-benefits-nbsp">Far-reaching benefits&nbsp;</h2>



Professor Santamouris noted that lowering the temperature of the city will help increase thermal comfort for people as well as reduce health issues from severe heat, decrease the concentration of pollutants, and improve human productivity.



Although not directly addressed in this study, previous research indicates that such cooling strategies can also reduce heat-related mortality.



<h2 class="wp-block-heading" id="h-energy-impact">Energy impact</h2>



The researchers examined the energy impact of retrofitting all 3,323 buildings in the precinct, in conjunction with the proposed urban-scale heat mitigation technologies.&nbsp;



By optimally combining cooling technologies with retrofitting measures – like better windows, insulation, and cool roofs – the cooling demand could be slashed by up to 35 percent.&nbsp;



“This represents a substantial reduction to the energy needs for Riyadh that would help further reduce costs associated with cooling for the city while improving the quality of life for the local population,” said Professor Santamouris.



<h2 class="wp-block-heading" id="h-study-implications-nbsp">Study implications&nbsp;</h2>



The researchers now hope to work with the Royal Commission of Riyadh to begin implementing their heat mitigation plan, which will be the largest of its kind in the world.



“Once implemented at the city scale, these advanced heat mitigation technologies will deliver important health, sustainability and economic outcomes for the city for years to come,” said Professor Santamouris.&nbsp;

Tackling urban heat: Experts plan to cool a desert city by 4.5°C

Scientists from the University of New South Wales (UNSW) Sydney...

New research from the <a href="https://www.colorado.edu/" target="_blank" rel="noreferrer noopener">University of Colorado Boulder</a> has unveiled alarming projections for acidity levels of Antarctic coastal waters.



By the century's end, the acidity in these waters could surge by over 100% compared to the 1990s, posing a grave threat to diverse marine life including whales, penguins, and numerous other species in the Southern Ocean.



Nicole Lovenduski, co-author of the study and interim director of CU Boulder’s Institute of Arctic and Alpine Research (<a href="https://www.colorado.edu/instaar/" target="_blank" rel="noreferrer noopener">INSTAAR</a>), emphasized the importance of these findings. 



“The findings are critical for our understanding of the future evolution of marine ecosystem health,” she stated. 



<h2 class="wp-block-heading" id="h-looming-acidity-crisis-in-antarctic-waters">Looming acidity crisis in Antarctic waters</h2>



The study highlights a worrying trend. The upper 650 feet (200 meters) of the ocean, a critical habitat for many marine organisms, is expected to experience this sharp increase in acidity.



Oceans worldwide act as buffers against climate change by <a href="https://www.earth.com/news/ocean-carbon-dioxide-sink/" target="_blank" rel="noreferrer noopener">absorbing</a> nearly 30% of CO2 emissions. However, this comes at a cost. 



Cara Nissen, the paper’s lead author and a research scientist at INSTAAR, pointed out, “Human-caused CO2 emissions are at the heart of ocean acidification,”



Particularly vulnerable is the <a href="https://www.earth.com/news/the-southern-ocean-is-a-critically-important-carbon-sink/" target="_blank" rel="noreferrer noopener">Southern Ocean</a> around Antarctica, where colder waters absorb more CO2 and unique ocean currents contribute to already acidic conditions.



<h2 class="wp-block-heading" id="h-how-the-study-was-conducted">How the study was conducted</h2>



Nissen, Lovenduski, and their team used computer models to simulate how the Southern Ocean's seawater might change throughout the 21st century. 



They discovered that without significant emission cuts, acidification would escalate drastically, affecting the entire water column, from surface to seabed.



The team's focus also included Antarctica’s <a href="https://www.earth.com/news/marine-protected-areas-improve-well-being-in-coastal-communities/" target="_blank" rel="noreferrer noopener">marine protected areas</a> (MPAs), zones where human activities like fishing are limited to conserve biodiversity. 



Despite these protections, both existing and proposed MPAs in Antarctic waters are likely to suffer significant acidification. 



Under a high-emission scenario, the <a href="https://www.earth.com/news/antarcticas-ross-sea-sanctuary-greenlighted/" target="_blank" rel="noreferrer noopener">Ross Sea region</a> -- the world's largest MPA -- could witness a 104% rise in water acidity by 2100 compared to the 1990s. Even under a moderate emission scenario, a 43% increase is expected.



Nissen expressed her astonishment at the severity of potential <a href="https://www.earth.com/news/preparing-for-ocean-acidification-a-silent-killer-of-climate-change/" target="_blank" rel="noreferrer noopener">ocean acidification</a> in these areas. “It’s surprising to me how severe ocean acidification would be in these coastal waters,” Nissen said. 



<h2 class="wp-block-heading" id="h-harm-caused-by-acidic-waters">Harm caused by acidic waters</h2>



Water acidity in Antarctica hamper the growth of <a href="https://www.earth.com/news/warmer-water-and-ocean-acidification-harm-important-plankton/" target="_blank" rel="noreferrer noopener">phytoplankton</a>, crucial to the marine food chain, and weaken the shells of organisms like <a href="https://www.earth.com/news/how-do-high-temperatures-affect-young-sea-snails/" target="_blank" rel="noreferrer noopener">sea snails</a> and <a href="https://www.earth.com/news/sea-urchins-are-struggling-to-survive-because-they-cant-get-a-grip/" target="_blank" rel="noreferrer noopener">sea urchins</a>, which could have cascading effects up to top predators.



The team also examined the <a href="https://www.earth.com/news/a23a-worlds-largest-iceberg-is-moving-after-30-years/" target="_blank" rel="noreferrer noopener">Weddell Sea</a>, one of the proposed MPAs. Known for its extensive sea ice coverage, which currently shields the region from warming and CO2 absorption, the area is seen as a potential climate change sanctuary. 



“The result shows that establishing the Weddell Sea region as a protected area should have high priority,” Nissen said. 



However, the study indicates that as global warming progresses, melting sea ice will lead to <a href="https://www.earth.com/news/antarctic-icefish-have-developed-alien-like-superpowers-to-survive/" target="_blank" rel="noreferrer noopener">acidification</a> similar to other MPAs, albeit slightly delayed. 



<h2 class="wp-block-heading" id="h-reverse-antarctica-water-acidity-is-crucial">Reverse Antarctica water acidity is crucial</h2>



Nissen emphasized the urgency of establishing the Weddell Sea as a <a href="https://www.earth.com/news/marine-protected-areas-are-not-immune-to-ocean-heatwaves/" target="_blank" rel="noreferrer noopener">protected area</a>.



"This study reminded me that these dynamic Antarctic coastal areas are also themselves capable of rapid change,” Lovenduski said, reflecting on the study's implications.



“As a scientist who typically studies the open ocean, I tend to think of Antarctic coastal areas as a conduit for climate signals to reach the global, deep ocean,"  Lovenduski concluded.



The research concludes with a stark warning: only an aggressive reduction in CO2 emissions can prevent severe <a href="https://www.earth.com/news/crabs-are-losing-their-sense-of-smell-and-vanishing-due-to-ocean-acidification/" target="_blank" rel="noreferrer noopener">ocean acidification</a> in the Southern Ocean. 



“We still have the opportunity to choose our path regarding emissions, but time is running out,” Nissen cautions. 



In summary, this study serves as a critical call to action, underscoring the urgent need for global cooperation in reducing emissions to protect these vital ecosystems.



The full study was published in the journal <a href="https://www.nature.com/articles/s41467-023-44438-x" target="_blank" rel="noreferrer noopener">Nature Communications</a>.

For most humans on our planet, bugs are often overlooked and sometimes swatted away. However, we need to learn to coexist, because insects and spiders, or arthropods, are pivotal to the <a href="https://www.earth.com/news/insects-play-important-roles-in-ecosystems/" target="_blank" rel="noreferrer noopener">ecosystems</a> humans depend on.



These creatures, characterized by their hard exoskeletons and jointed legs, constitute a staggering 84% of known animal species. Their role in our urban landscapes is more critical than many realize.



<h2 class="wp-block-heading" id="h-how-humans-and-bugs-interact">How humans and bugs interact</h2>



Recent research has shed light on how human activities influence <a href="https://www.earth.com/news/global-insect-decline-what-are-the-causes-and-consequences/" target="_blank" rel="noreferrer noopener">insect biodiversity</a>. The study, a collaboration between <a href="https://dornsife.usc.edu/" target="_blank" rel="noreferrer noopener">USC Dornsife College</a> and the Natural History Museum of Los Angeles County's <a href="https://nhm.org/community-science-nhm/bioscan" target="_blank" rel="noreferrer noopener">BioSCAN project</a>, focuses on nonbiological factors like temperature fluctuations and proximity to the ocean and their impact on arthropods in urban settings.



The BioSCAN project, bolstered by around 80 volunteers, involved setting up Malaise traps across Los Angeles to collect various flying arthropods, including bees, flies, and moths. 



Spiders were also hand-collected in these areas. This community science initiative played a vital role in understanding the <a href="https://www.earth.com/news/insect-declines-in-europe-linked-to-human-activities/" target="_blank" rel="noreferrer noopener">arthropod diversity</a> in the bustling metropolis.



<h2 class="wp-block-heading" id="h-insects-have-diverse-responses-to-humans">Insects have diverse responses to humans</h2>



<a href="https://dornsife.usc.edu/profile/laura-melissa-guzman/" target="_blank" rel="noreferrer noopener">Melissa Guzman</a>, the study's lead researcher and Assistant Professor of <a href="https://dornsife.usc.edu/bisc/" target="_blank" rel="noreferrer noopener">Biological Sciences</a> and <a href="https://www.qcb-dornsife.usc.edu/" target="_blank" rel="noreferrer noopener">Quantitative and Computational Biology</a> at USC Dornsife, highlighted the unexpected diversity in bug responses to humans in urban environmental factors.



These included land covered by asphalt or concrete, and daily temperature changes. Contrary to initial thoughts, these factors had varied impacts across different arthropod groups.



For instance, the prevalence of concrete and asphalt surfaces increased the diversity of fruit flies but decreased that of crane flies. 



“In general, we thought most <a href="https://www.earth.com/news/common-insect-species-face-the-greatest-declines/" target="_blank" rel="noreferrer noopener">arthropods</a> would be similarly affected by environmental factors such as land covered by asphalt or concrete and temperature fluctuations over a 24-hour cycle,” said Guzman.



“Instead, we found an unexpectedly large range of responses to factors such as these, both within closely related groups and across different groups.”



<a href="https://www.earth.com/news/natural-pest-control-tree-species-diversity-increases-spider-density/" target="_blank" rel="noreferrer noopener">Spiders</a>, interestingly, thrived in these hard-covered areas. Temperature variations also significantly influenced the diversity of specific <a href="https://www.earth.com/news/extreme-weather-has-increased-seasonal-insect-activity/" target="_blank" rel="noreferrer noopener">insect families</a>.



The researchers theorize that summertime's higher temperatures cause the drying up of plants that aphids feed on, thus depleting a primary food source for many hover flies. 



Additionally, they observe that non-native honeybees increase their foraging in warmer temperatures, directly competing for the same food resources as some hover flies.



<h2 class="wp-block-heading" id="h-urban-planning-and-biodiversity">Urban planning and biodiversity</h2>



These insights are crucial for urban planners and developers. Understanding the link between <a href="https://www.earth.com/news/why-do-so-few-insect-species-live-in-the-ocean-scientists-think-they-know/" target="_blank" rel="noreferrer noopener">species diversity</a> and factors like land value and temperature can guide adjustments in urban projects to enhance biodiversity. 



This, in turn, brings numerous benefits, including improved air quality, flood risk reduction, and better mental health for city dwellers.



Brian Brown, entomology curator at the Natural History Museum, revealed an exciting outcome. They discovered many <a href="https://www.earth.com/news/insect-larvae-had-sophisticated-defense-strategies-100-million-years-ago/" target="_blank" rel="noreferrer noopener">arthropod species</a> previously unknown in the L.A. area, including about 50 new to science. 



“Based on that, we have a new understanding of what the biodiversity of Los Angeles is like in terms of <a href="https://www.earth.com/news/insect-populations-are-headed-towards-widespread-chaos-in-our-continually-warming-world/" target="_blank" rel="noreferrer noopener">insects</a>,” he said. “So instead of the 3,500 or 4,000 species that we previously thought, now we’re thinking there are close to 20,000 species living here in the ‘city of insects.’”



In a heartwarming tribute, each newly discovered species was named after a family participating in the BioSCAN project, emphasizing the crucial role of community involvement in conservation efforts.



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



Despite some limitations, like not accounting for seasonal variations in weather, the study offers practical ways for Los Angeles residents to enhance arthropod biodiversity. 



Guzman suggests prioritizing green areas, reducing pesticide use, and designing microhabitats in urban developments to support <a href="https://www.earth.com/news/rise-and-fall-of-insect-populations-directly-linked-to-the-weather/" target="_blank" rel="noreferrer noopener">diverse species</a>.



“Prioritizing green areas and reducing the use of pesticides would go a long way,” Guzman says. “And urban planners and builders could include microhabitats designed to allow a greater variety of species to thrive.”



While focused on Los Angeles, the study's findings have broader implications for urban environments across western North America. 



By understanding and applying these insights, land developers and homeowners can play a significant role in nurturing and preserving the delicate balance of urban ecosystems.



In summary, the study emphasizes the often-unseen diversity of urban wildlife and provides a roadmap for fostering healthy, resilient urban ecosystems. 



Through community involvement and informed urban planning, we can ensure that our cities remain vibrant havens for diverse life forms.

Do bugs bug humans more than humans bug bugs?

For most humans on our planet, bugs are often overlooked...

Global warming demands immediate and effective actions. One critical aspect of tackling this challenge is the reduction of greenhouse gas <a href="https://www.earth.com/news/epa-plans-to-eliminate-greenhouse-gas-emissions-from-power-plants-by-2040/">emissions</a>, specifically carbon dioxide (CO2).&nbsp;



Traditional approaches are not sufficient to meet the ambitious climate targets set by the global community. Consequently, there is a growing emphasis on innovative methods to capture CO2 directly from the atmosphere.



<h2 class="wp-block-heading" id="h-carbon-capture-technologies-nbsp">Carbon capture technologies&nbsp;</h2>



Current carbon capture technologies are energy-intensive and costly. This limitation highlights the urgent need for alternative, efficient methods.&nbsp;



A team of researchers at <a href="https://ethz.ch/en.html" target="_blank" rel="noreferrer noopener">ETH Zurich</a> led by Professor Maria Lukatskaya has developed a novel approach to direct CO2 capture by harnessing the power of sunlight.&nbsp;



<h2 class="wp-block-heading" id="h-chemical-phenomenon-nbsp">Chemical phenomenon&nbsp;</h2>



In acidic aqueous solutions, CO2 exists in its original state, while in alkaline solutions, it converts to carbonates. This reaction is reversible, depending on the solution's acidity.



To manipulate this acidity, the ETH team introduced photoacids into the solution. These special molecules respond to light. In the presence of light, they acidify the liquid, and in darkness, they revert, making the liquid more alkaline.



<h2 class="wp-block-heading" id="h-breakthrough-technique-nbsp">Breakthrough technique&nbsp;</h2>



The process begins by passing air through an alkaline solution containing photoacids in the dark, causing CO2 to react and form carbonates.&nbsp;



Once a significant amount of carbonates accumulate, the solution is exposed to light, turning acidic and releasing CO2 gas, similar to the effervescence observed in a cola bottle. The released CO2 is then collected in gas tanks. After most CO2 is expelled, the light is turned off, and the cycle restarts.



<h2 class="wp-block-heading" id="h-overcoming-challenges-nbsp">Overcoming challenges&nbsp;</h2>



Initially, the researchers found that the photoacids were unstable in water. “In the course of our earliest experiments, we realized that the molecules would decompose after one day,” said study lead author Anna de Vries.



To overcome this, the team experimented with a mix of water and an organic solvent, eventually finding an optimum ratio that stabilized the photoacids for nearly a month and allowed the required reversible reaction.



<h2 class="wp-block-heading" id="h-advantages-over-traditional-methods">Advantages over traditional methods</h2>



The new technique stands out from existing carbon capture processes, which typically involve cyclical temperature-based systems requiring significant energy for heating and cooling.&nbsp;



By contrast, the ETH Zurich method is more energy-efficient as it eliminates the need for heating, potentially operating solely on sunlight.



“Another interesting aspect of our system is that we can go from alkaline to acidic within seconds and back to alkaline within minutes. That lets us switch between carbon capture and release much more quickly than in a temperature-​driven system,” explained de Vries.



Looking ahead, the researchers aim to enhance the stability of photoacid molecules and optimize the process parameters for potential market application.

Sunlight may be the secret weapon for direct CO2 capture 

Global warming demands immediate and effective actions. One critical aspect...

A new study has revealed that the world's <a href="https://www.earth.com/news/half-of-americas-beaches-contain-alarming-levels-of-fecal-contamination/">beaches</a> and dunes are under significant threat due to a phenomenon known as "coastal squeeze." This issue stems from the encroachment of roads and buildings on these natural landscapes.



Coastal squeeze has adverse effects on biodiversity, drinking water supplies, and our protection against rising sea levels. However, the research provides a glimmer of hope, showing that beaches and dunes can be effectively safeguarded through the designation of nature reserves.



The study was led by a team of experts from the <a href="https://www.nioz.nl/en" target="_blank" rel="noreferrer noopener">Netherlands Institute for Sea Research</a>, University of Groningen, Utrecht University, TU Delft, and the Dutch Forestry Commission.



<h2 class="wp-block-heading" id="h-startling-reality">Startling reality</h2>



The research highlights a startling reality: on average, a mere 390-meter walk from any given point on a beach leads to the nearest road or building.&nbsp;



This proximity, while seemingly convenient for beachgoers, actually spells disaster for the environment.&nbsp;



<h2 class="wp-block-heading" id="h-vital-functions-nbsp">Vital functions&nbsp;</h2>



Beaches and dunes serve as crucial natural barriers against flooding and important habitats for diverse wildlife.&nbsp;



But as these areas become increasingly boxed in by human infrastructure on one side and rising sea levels on the other, their ability to perform these vital functions is severely compromised.



<h2 class="wp-block-heading" id="h-extensive-data-analysis">Extensive data analysis</h2>



To quantify the extent of coastal squeeze, the team used a combination of previous measurement data from TU Delft.&nbsp;



The researchers conducted an extensive survey, measuring the straight-line distance from the coastline to the nearest paved road or building along all the sandy beaches globally. This meticulous process involved 235,469 individual measurements.



<h2 class="wp-block-heading" id="h-key-findings">Key findings</h2>



The study revealed that on a global scale, human infrastructure is alarmingly close to the sea, with the average distance to the first building or paved road being just 390 meters.&nbsp;



The situation is even more dire in densely populated regions like the Netherlands (210 meters) and France (30 meters). Europe emerges as the continent with the most constrained beaches and dunes, averaging a distance of only 130 meters, in contrast to Oceania's 2.8 kilometers.



<h2 class="wp-block-heading" id="h-future-outlook">Future outlook</h2>



Looking ahead, the issue of coastal squeeze is expected to worsen due to rising sea levels. In a natural scenario, beaches and dunes would migrate inland to adapt, but the presence of buildings and roads obstructs this natural process.&nbsp;



The researchers project that by 2100, up to 30 percent of the world's beaches and dunes could be eroded or submerged.



<h2 class="wp-block-heading" id="h-nature-reserves-offer-hope">Nature reserves offer hope</h2>



The study, however, offers hope that the establishment of nature reserves could help prevent the negative impacts of coastal squeeze. Areas with protected status exhibit a significantly greater distance between infrastructure and the coastline.&nbsp;



"Encouragingly, we find that nature reserves relieve squeezing by 4-7 times. Yet, at present only 16% of world’s sandy shores have a protected status. We therefore advocate the incorporation of nature protection into spatial planning policies," wrote the study authors.

Shrinking shores: Beaches need protection from coastal squeeze

A new study has revealed that the world's beaches and...

A recent report published in the journal <a href="http://dx.doi.org/10.1038/s41558-023-01900-4" target="_blank" rel="noreferrer noopener">Nature Climate Change</a> emphasizes the crucial role of addressing inequality in achieving net-zero <a href="https://www.earth.com/news/global-co2-emissions-expected-to-reach-a-new-high-in-2023/">carbon emissions</a>. The researchers argue that inequality significantly limits individuals' capacity to adopt low-carbon behaviors, calling for societal changes and political acknowledgment of these barriers.



<h2 class="wp-block-heading" id="h-various-forms-of-inequality-nbsp">Various forms of inequality&nbsp;</h2>



The report, authored by Dr. Charlotte Kukowski, a postdoctoral researcher at the <a href="https://www.cam.ac.uk/">University of Cambridge</a>, and Dr. Emma Garnett, a postdoctoral researcher at the <a href="https://www.ox.ac.uk/">University of Oxford</a>, highlights various forms of inequality, including wealth, income, political influence, free time, and access to low-carbon options like public transport and housing insulation subsidies.



“It’s increasingly acknowledged that there’s inequality in terms of who causes climate change and who suffers the consequences, but there’s far less attention being paid to the effect of inequality in changing behaviors to reduce carbon emissions,” Kukowski said, noting that those on lower incomes face more restrictions in reducing their carbon footprint due to cost and time constraints.



<h2 class="wp-block-heading" id="h-financial-inequalities-nbsp">Financial inequalities&nbsp;</h2>



The report details how deep-rooted inequalities hinder the shift to lower-carbon behaviors. For instance, in the UK, insulating a house can be costly, with subsidies mainly available for homeowners, leaving renters with little control over their living conditions.&nbsp;



The UK's old, poorly insulated houses demand more energy for heating, necessitating government schemes that aid lower-income groups in reducing home carbon emissions.



Similarly, plant-based meat alternatives, though more sustainable, are often less affordable than animal products. Despite the significant impact of eating more plant-based foods on carbon footprint reduction, the cost makes it less accessible for those on lower incomes.



<h2 class="wp-block-heading" id="h-inability-to-change-behaviors-nbsp">Inability to change behaviors&nbsp;</h2>



The researchers also highlight the challenges in acquiring electric vehicles and bikes due to their high upfront costs and the inaccessibility of tax breaks or financing for those not in permanent employment. Additionally, inadequate public transport services, especially in rural areas, make it difficult for many to opt for this lower-carbon transport method.



“If you have more money you're likely to cause more carbon emissions, but you're also more likely to have greater ability to change the things you do and reduce those emissions,” Garnett explains. She stresses the need for interventions targeting high emitters and making lower-carbon choices in areas like food and transport accessible to everyone.



<h2 class="wp-block-heading" id="h-overcoming-the-barriers-to-change">Overcoming the barriers to change</h2>



The researchers criticize current campaigns focusing mainly on providing information, pointing out that understanding the issues doesn't automatically overcome barriers to change.&nbsp;



"Policies and psychological approaches often overemphasize individual agency, overlooking how socioeconomic inequality can constrain access to low-carbon alternatives. We argue that tackling these inequalities is urgent for impactful, equitable behavior change," wrote the experts.&nbsp;



The experts propose policy interventions, such as urban planning for bus and bike lanes, progressive taxation, and employer-subsidized low-carbon meal options, to facilitate more inclusive and practical ways for people to adopt lower-carbon lifestyles.



This report underscores the intricate link between socio-economic inequality and environmental sustainability, advocating for comprehensive strategies that address both to effectively combat climate change.

Reducing inequality is a major battle in the war against climate change

A recent report published in the journal Nature Climate Change...

Many,Red,Sea,Fans,And,White,Cluster,Sea,Whip,Coral

Researchers have unveiled a new ally in the fight to protect corals against the ravages of ocean warming: a unique single-celled microbe. This discovery marks a pivotal moment in our understanding of <a href="https://www.earth.com/news/coral-reefs-in-some-parts-of-the-world-actually-benefit-from-warming-el-nino-events/" target="_blank" rel="noreferrer noopener">coral resilience</a>, especially in the face of escalating ocean-warming events such as bleaching.



The study was spearheaded by a team from the University of Miami <a href="https://www.earth.miami.edu/" target="_blank" rel="noreferrer noopener">Rosenstiel School</a> of Marine, Atmospheric, and Earth Science, alongside colleagues from the Institute of Evolutionary Biology (<a href="https://www.ibe.upf-csic.es/">IBE: CSIC-UPF</a>) in Barcelona. 



The team highlights the intricate role microbes play in bolstering <a href="https://www.earth.com/news/recent-coral-recovery-in-the-great-barrier-reef-has-paused/" target="_blank" rel="noreferrer noopener">coral</a> defenses against the severe impacts of end-of-century heat stress and climate change projections.



<h2 class="wp-block-heading" id="h-microbial-indicator-of-coral-resilience">Microbial indicator of coral resilience</h2>



At the heart of this research lies the revelation that specific protists within the <a href="https://www.earth.com/news/devastating-coral-bleaching-is-expected-around-the-world-within-the-next-year/" target="_blank" rel="noreferrer noopener">coral</a> microbiome -- the diverse microorganisms residing in corals -- can serve as indicators of a coral's ability to endure heat stress. 



This insight is particularly vital for <a href="https://www.earth.com/news/massive-study-provides-answers-to-how-coral-reefs-can-survive-climate-change/" target="_blank" rel="noreferrer noopener">corals</a> worldwide as they increasingly confront more frequent ocean warming events. 



The study places a spotlight on corals devoid of zooxanthellae, a type of symbiotic algae expelled during warm water-induced bleaching, underlining their vulnerability.



“This is the first time that a non-algae microbe has been shown to influence the ability of corals to survive a heat-stress event,” reveals Javier del Campo, the study’s senior author, adjunct assistant professor at the Rosenstiel School, and principal investigator of the IBE. 



He emphasizes the critical need for a comprehensive understanding of the microbial factors affecting <a href="https://www.earth.com/news/coral-growth-cannot-keep-pace-with-rising-sea-levels/" target="_blank" rel="noreferrer noopener">coral</a> survivability to guide conservation strategies, particularly in prioritizing corals for intervention amid climate change.



“As corals face more and more heat-stress events due to climate change, a better understanding of all the microbes that may influence survivability can inform conservation practitioners as to which <a href="https://www.earth.com/news/nutrients-from-seabird-poop-accelerate-coral-reef-recovery/" target="_blank" rel="noreferrer noopener">corals</a> they should prioritize for intervention," del Campo explained.



<h2 class="wp-block-heading" id="h-how-the-study-was-conducted">How the study was conducted</h2>



To arrive at these findings, the international research team embarked on a meticulous journey. 



They collected samples of the violescent sea-whip (Paramuricea clavata), a vital architect of the Mediterranean temperate reefs currently facing the threats of mass mortality due to global warming. 



In the lab, they analyzed the coral’s microbiome and subjected it to natural heat-stress conditions, observing signs of mortality.



The study identified a group of single-celled parasitic protists, known as Syndiniales, that are more prevalent in <a href="https://www.earth.com/news/unexpected-coral-adaptations-challenge-conservation-plans/" target="_blank" rel="noreferrer noopener">corals surviving</a> heat stress. 



In contrast, Corallicolids -- protists closely related to human malaria parasites -- are found more abundantly in corals succumbing to heat stress.



<h2 class="wp-block-heading" id="h-new-horizon-in-coral-conservation">New horizon in coral conservation</h2>



Protists, or single-cell eukaryotes, are less studied than bacteria in most host organisms but may have a major influence on the health of their coral host. 



del Campo underscores the importance of considering all members of the microbiome, from bacteria to protists, in assessing <a href="https://www.earth.com/news/some-corals-survive-warming-waters-by-remembering-heat-waves/" target="_blank" rel="noreferrer noopener">coral health</a>.



“The microbiome is a vital component of coral host health and we should study all members of it from the bacteria to the protists,” said del Campo.



In summary, this study unveils a critical microbial player in the coral ecosystem, while clearing new paths for more targeted conservation efforts. 



Understanding the complex interplay of various microorganisms within corals is crucial in developing strategies to bolster coral resilience against the escalating challenges posed by climate change.



<h2 class="wp-block-heading" id="h-more-about-sea-whip-coral-and-their-microbes">More about sea-whip coral and their microbes</h2>



As mentioned above, sea-whips, captivating marine organisms, claim their place in the underwater world with their unique, whip-like structures. 



These intriguing sea creatures, belonging to the soft <a href="https://www.earth.com/news/deepest-known-coral-reef-bleaching-discovered-alarming-scientists/" target="_blank" rel="noreferrer noopener">coral</a> family, paint the ocean floor with their vivid colors and intricate forms. 



Unlike their hard coral cousins, sea-whips lack a rigid calcium carbonate skeleton, allowing them a flexibility that adds a dynamic element to the seascape.



<h3 class="wp-block-heading" id="h-anatomy-and-habitat">Anatomy and habitat</h3>



Sea-whips exhibit a fascinating anatomy. They consist of a central, whip-like skeleton covered in polyps, tiny animals that make up the living part of the <a href="https://www.earth.com/news/coral-skeletons-improve-reef-recovery-after-bleaching/" target="_blank" rel="noreferrer noopener">coral</a>. 



These polyps possess stinging cells, enabling them to capture tiny organisms for nutrition. Sea-whips thrive in a variety of marine environments, from shallow reefs to deep-sea floors, displaying an incredible adaptability to different ocean conditions.



Sea-whips play a crucial role in marine ecosystems. They serve as habitats for a multitude of marine species, offering shelter and breeding grounds. 



Fish, crustaceans, and other sea creatures often seek refuge within the branches of sea-whips, finding protection from predators and harsh environmental conditions.



<h3 class="wp-block-heading" id="h-threats-and-conservation-efforts">Threats and conservation efforts</h3>



Despite their resilience, sea-whips face several threats, primarily from human activities. Overfishing, pollution, and destructive fishing practices, like trawling, pose significant risks to their survival. 



Additionally, climate change and the resulting ocean acidification and warming further exacerbate these challenges. Thankfully, as discussed above, single-celled microbes are proving adept at protecting these <a href="https://www.earth.com/news/coral-skeletons-improve-reef-recovery-after-bleaching/" target="_blank" rel="noreferrer noopener">coral</a> from climate change.



Conservation efforts focus on protecting sea-whip habitats, promoting sustainable fishing practices, and raising awareness about the importance of these delicate marine organisms.



Sea-whips attract considerable scientific interest due to their unique biological properties. Researchers study them for insights into coral growth, reproduction, and resilience. 



Moreover, sea-whips are of interest in the field of biomedicine for their potential in drug discovery, as they produce a range of bioactive compounds.



In summary, sea-whips stand as guardians of the ocean's beauty and biodiversity. Their presence adds to the aesthetic value of the underwater world while playing a pivotal role in maintaining the health and balance of marine ecosystems. 



Protecting these magnificent creatures is essential for preserving the richness and diversity of life beneath the waves.

A single-celled microbe is protecting corals from heat and helping them survive climate change

Researchers have unveiled a new ally in the fight to...

A recent study conducted by an international team of scientists from China, the United States, New Zealand, Italy, and France has shed light on alarming trends in <a href="https://www.earth.com/news/limiting-global-warming-to-1-5-degrees-celsius-would-save-billions-of-lives/">global warming</a>, with a particular focus on ocean temperatures.&nbsp;



The comprehensive analysis confirms that 2023 was the hottest year on record, continuing a decade-long pattern where each year surpassed the previous in ocean heat levels.



<h2 class="wp-block-heading" id="h-the-ocean-s-role-in-climate">The ocean's role in climate</h2>



Covering 70% of the planet, the ocean is a crucial component of the Earth's climate system. It absorbs about 90% of the heat generated by global warming, significantly influencing atmospheric conditions. A warmer ocean leads to a warmer atmosphere that holds more moisture, resulting in extreme weather patterns.&nbsp;



Furthermore, the ocean plays a pivotal role in dictating the pace of climate change, making it a key focus for understanding future climatic shifts.



<h2 class="wp-block-heading" id="h-data-analysis-nbsp">Data analysis&nbsp;</h2>



The data, derived from two prominent research teams - the Institute of Atmospheric Physics (IAP) at the Chinese Academy of Sciences (CAS) and the National Centers for Environmental Information of the National Oceanic and Atmospheric Administration (NOAA) - present a concerning picture.&nbsp;



The IAP analysis showed an increase in ocean temperature by 15 zettajoules compared to 2022, while NOAA's findings indicated a slightly lower increase of 9 zettajoules. Despite these differences, both groups agree on the overall trend of ocean warming.



<h2 class="wp-block-heading" id="h-understanding-zettajoules">Understanding zettajoules</h2>



To put these figures into perspective, the entire global energy consumption annually is about half a zettajoule. Therefore, 15 zettajoules is an immense amount of energy - equivalent to the energy it would take to boil away 2.3 billion Olympic-sized swimming pools.



The discrepancy in data between IAP and NOAA has prompted further investigation. Early evidence suggests that the differences may stem from varying methodologies in data handling, particularly in quality control and the mapping of individual data points onto a global grid. In a warming climate, it's possible that new high ocean temperature measurements could be mistakenly discarded.



“What this means is the warming might be greater than the numbers reported here," explained study lead author Dr. Lijing Cheng from IAP/CAS.



<h2 class="wp-block-heading" id="h-shifting-ocean-composition">Shifting ocean composition</h2>



The experts also noted shifts in rainfall and evaporation patterns, altering ocean salinity. These changes affect marine life and ocean currents.&nbsp;



In addition, the increasing stratification of the ocean, where less dense, warm, and fresh waters remain near the surface, impedes the ocean's ability to transport heat and carbon dioxide to deeper layers. This leads to reduced oxygen levels and a diminished capacity for carbon dioxide absorption, adversely affecting marine wildlife.



<h2 class="wp-block-heading" id="h-warming-oceans-and-extreme-weather">Warming oceans and extreme weather</h2>



A warmer ocean supercharges weather systems, contributing to more severe storms with heavier rainfall, stronger winds, and significant flooding.&nbsp;



The economic and human costs of these events are staggering. In the United States alone, damages are estimated at approximately $200 billion per year.



These findings highlight the urgent need to halt the burning of fossil fuels and reduce carbon dioxide emissions. Transitioning to renewable energy sources such as wind, solar, and hydropower is critical for decarbonizing the economy and mitigating the impacts of climate change.&nbsp;



The study is published in the journal <a href="http://dx.doi.org/10.1007/s00376-024-3378-5" target="_blank" rel="noreferrer noopener">Advances in Atmospheric Sciences</a>.&nbsp;

Ocean temperatures were a driving force behind 2023's record heat

A recent study conducted by an international team of scientists...

A new study has unveiled a startling truth about bottled water: it can contain hundreds of thousands of nanoplastics, a number that far exceeds previous estimates.



For the investigation, researchers at <a href="https://www.climate.columbia.edu/" target="_blank" rel="noreferrer noopener">Columbia Climate School</a> used a novel microscopic technique focused on nanoplastics, which is a largely unexplored domain. 



These tiny particles, the offspring of <a href="https://www.earth.com/news/humans-inhale-the-equivalent-of-a-credit-card-in-microplastics-each-week/">microplastics</a>, pose potential threats to human health and ecosystems, as they can infiltrate blood, cells, and even the brain.



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



For years, <a href="https://www.earth.com/news/microplastics-deadly-and-widespread-environmental-pollutants/" target="_blank" rel="noreferrer noopener">microplastics</a> -- particles formed from the breakdown of larger plastics -- have been a growing concern. They have been found in diverse environments ranging from Arctic ice to everyday items like drinking water and food.&nbsp;



However, the focus has now shifted to bottled water, which was already known to contain thousands of microplastic fragments.



<a href="https://www.earth.com/news/zooplankton-are-rapidly-escalating-the-threat-of-nanoplastics/" target="_blank" rel="noreferrer noopener">Nanoplastic</a> comprises ever smaller fragments derived from microplastics. The Columbia team counted and identified these nanoplastics in bottled water, discovering an average of 240,000 fragments per liter -- a number 10 to 100 times greater than earlier estimates.



Nanoplastics, unlike their larger counterparts, can bypass the intestines and lungs, entering the bloodstream directly. From there, they can travel to various organs, including the heart and brain. 



Their ability to invade individual cells and cross the placenta raises significant concerns about their impact on human health.



<h2 class="wp-block-heading" id="h-finding-nanoplastics-in-bottled-water">Finding nanoplastics in bottled water</h2>



The new detection technique used for the study, stimulated Raman scattering microscopy, was co-invented by study co-author Wei Min. 



This method allows for precise identification of <a href="https://www.earth.com/news/nanoplastics-can-easily-travel-through-food-webs/" target="_blank" rel="noreferrer noopener">nanoparticles</a> and provides a clearer understanding of what these particles are and their potential toxicity.



Study co-author Beizhan Yan, an environmental chemist at Columbia University’s <a href="https://lamont.columbia.edu/" target="_blank" rel="noreferrer noopener">Lamont-Doherty Earth Observatory</a>, highlighted the novelty of this research.&nbsp;



“Previously this was just a dark area, uncharted. Toxicity studies were just guessing what’s in there,” said Yan. “This opens a window where we can look into a world that was not exposed to us before.”



Globally, plastic production is approaching 400 million metric tons annually, with over 30 million tons discarded into water bodies or landfills.



Unlike organic matter, plastics do not degrade into harmless substances. Instead, they continue to break down into <a href="https://www.earth.com/news/microwaving-baby-food-containers-releases-billions-of-nanoplastics/" target="_blank" rel="noreferrer noopener">smaller particles</a>, potentially down to the molecular level.&nbsp;



<h2 class="wp-block-heading" id="h-alarming-discovery-nbsp">Alarming discovery&nbsp;</h2>



Nanoplastics are defined as particles smaller than one micrometer, measured in billionths of a meter. This is significantly smaller than microplastics.&nbsp;



The discovery of these nanoplastics in bottled water is particularly alarming, considering their potential for <a href="https://www.earth.com/news/nanotoxicology-could-help-assess-the-risks-of-microplastics/" target="_blank" rel="noreferrer noopener">biological interaction</a>.



The issue of plastics in bottled water came to the forefront following a 2018 study that detected 325 particles per liter. However, this new research suggests that the actual number could be exponentially higher.&nbsp;



The challenge has been in detecting particles smaller than one micrometer, which marks the boundary of the nano world.



<h2 class="wp-block-heading" id="h-identifying-nanoplastics">Identifying nanoplastics</h2>



Study lead author Naixin Qian, a Columbia graduate student in Chemistry, explained the limitations of previous studies in identifying nanoplastics.



“People developed methods to see <a href="https://www.earth.com/news/microplastic-pollution-found-in-every-aquatic-species-tested/" target="_blank" rel="noreferrer noopener">nanoparticles</a>, but they didn’t know what they were looking at,” said Qian. She noted that previous studies could provide bulk estimates of nano mass, but for the most part could not count individual particles, nor identify which were plastics or something else.



The new technique allows for not only detecting these particles but also identifying their composition. This understanding is crucial for assessing the potential health risks posed by different types of <a href="https://www.earth.com/news/plastics-can-be-passed-from-mothers-to-unborn-babies/" target="_blank" rel="noreferrer noopener">plastics</a>.



In their analysis, the researchers found that polyethylene terephthalate (PET), commonly used in water bottles, was not the most abundant plastic.&nbsp;



Instead, polyamide, a type of nylon likely originating from water purification processes, was more prevalent. This indicates that even processes meant to purify water may contribute to the problem.



<h2 class="wp-block-heading" id="h-bottled-water-nanoplastics-and-future-research">Bottled water, nanoplastics, and future research</h2>



An intriguing aspect of the study was the discovery that the seven types of plastics identified accounted for only about 10% of all the nanoparticles found.



This means that a vast array of unknown particles are present in bottled water, emphasizing the complexity of this issue.



The team is expanding their research beyond bottled water to include tap water and other sources of potential nanoplastic contamination.&nbsp;



Collaborative efforts are underway to study nanoplastics in different environments, including Antarctic snow and human tissues, to better understand their ecological and health impacts.



“There is a huge world of nanoplastics to be studied,” said Min. He noted that by mass, nanoplastics comprise far less than microplastics, but “it’s not size that matters. It’s the numbers, because the smaller things are, the more easily they can get inside us.”



<h2 class="wp-block-heading" id="h-more-about-nanoplastics">More about nanoplastics</h2>



As discussed above, nanoplastics are minuscule fragments of plastic, much smaller than microplastics, often measuring less than 100 nanometers in size. 



Despite their tiny dimensions, these particles pose a significant environmental threat due to their widespread presence and potential to harm ecosystems and human health.



<h3 class="wp-block-heading">Origins of nanoplastics</h3>



The origin of nanoplastics primarily lies in the breakdown of larger plastic debris. Over time, factors such as sunlight, physical abrasion, and biological degradation reduce these larger pieces into increasingly smaller fragments. 



Additionally, nanoplastics can originate from consumer products like cosmetics and industrial processes.



Once in the environment, nanoplastics present unique challenges. Their small size allows them to evade filtration systems and disperse widely in water bodies and soils. 



This widespread distribution raises concerns about their accumulation in the food chain, as they can be ingested by a wide range of organisms, from plankton to larger animals.



<h3 class="wp-block-heading">Impact on organisms and human health</h3>



The impact of nanoplastics on living organisms is a topic of ongoing research. Studies suggest that these particles can cause physical and chemical harm. 



Physically, they can clog the digestive systems of aquatic animals and reduce nutrient absorption. 



Chemically, nanoplastics may release toxic additives or adsorb harmful pollutants from their surroundings, introducing these substances into organisms that ingest them.



For human health, the implications are equally concerning. Nanoplastics can potentially enter the human body through the consumption of contaminated food and water or inhalation. Once inside, they might cause inflammatory responses or release toxic substances.



<h3 class="wp-block-heading">Addressing the nanoplastic problem in bottled water</h3>



Addressing the nanoplastics issue requires a multifaceted approach. Reducing plastic waste at the source is crucial. 



This reduction can be achieved through better waste management practices, promoting the use of biodegradable materials, and enhancing public awareness about the impact of plastic pollution. 



Additionally, advancing filtration and remediation technologies to capture and remove nanoplastics from the environment is essential.



In summary, nanoplastics represent a growing environmental hazard. Understanding their behavior, impacts, and methods to mitigate their presence is vital for preserving ecosystems and safeguarding human health. 



It's a global challenge that demands immediate and sustained action from individuals, industries, and governments worldwide.

Over 240,000 cancer-causing nanoplastics found in bottled water

A new study has unveiled a startling truth about bottled...

Rain,Forest

In a monumental international effort led by University College London (<a href="https://www.ucl.ac.uk/" target="_blank" rel="noreferrer noopener">UCL</a>) researchers, a team of 356 scientists has made a startling discovery about tree species in the world's <a href="https://www.earth.com/news/tropical-trees-use-social-distancing-to-promote-forest-diversity/" target="_blank" rel="noreferrer noopener">tropical forests</a>. 



Their study, encompassing over a million trees across 1,568 distinct tropical locations, reveals a strikingly uniform pattern of tree diversity spanning tropical forests in Africa, the Amazon, and Southeast Asia.



<h2 class="wp-block-heading" id="h-significance-of-tree-diversity-in-tropical-forests">Significance of tree diversity in tropical forests</h2>



This extensive study marks the first of its kind to scrutinize the most prevalent tree species in these biodiverse-rich regions. 



What emerges from their analysis is a revelation that a mere 2.2% of tree species constitute half of the total tree population in these <a href="https://www.earth.com/news/tree-plantations-have-hidden-impacts-on-tropical-biodiversity/" target="_blank" rel="noreferrer noopener">tropical forests</a>. This uniformity is remarkable, considering the vast geographical and environmental differences across the continents. 



Dr. Declan Cooper, the lead author from UCL's Geography Department and the Centre for Biodiversity and Environment Research, underscores the significance of these findings. 



He explains, "Our findings have profound implications for understanding <a href="https://www.earth.com/news/tropical-trees-higher-elevations/" target="_blank" rel="noreferrer noopener">tropical forests</a>. Focusing on the commonest tree species can help predict the entire forest's response to rapid environmental changes." 



This is crucial given the role of <a href="https://www.earth.com/news/tropical-forests-are-losing-their-carbon-storage-capacity/" target="_blank" rel="noreferrer noopener">tropical forests</a> as significant carbon stores and their global significance as carbon sinks.



Dr. Cooper further elucidates, "Identifying the prevalence of the most common species offers a new lens through which to view tropical forests. Tracking these species could revolutionize how we assess forest health and predict future ecological changes."



<h2 class="wp-block-heading" id="h-understanding-tree-diversity-across-continents">Understanding tree diversity across continents</h2>



The <a href="https://www.earth.com/news/the-amazon-rainforest-and-the-looming-threat-of-drought/" target="_blank" rel="noreferrer noopener">Amazon</a> encompasses a vast, interconnected forest region, in contrast to Southeast Asia's predominantly fragmented island landscape. 



<a href="https://www.earth.com/news/indigenous-amazon-rainforest-dwellers/" target="_blank" rel="noreferrer noopener">Human settlements</a> appeared in the Amazon approximately 20,000 years ago, much later than in the African and Southeast Asian forests, where people have resided for over 40,000 years. 



Currently, African forests undergo a climate that is drier and cooler compared to their counterparts in the Amazon and Southeast Asia.



Whether it's the expansive, interconnected forests of the <a href="https://www.earth.com/news/amazons-rainforests-are-at-risk-of-transforming-into-dry-grassy-savannas/" target="_blank" rel="noreferrer noopener">Amazon</a>, the fragmented island ecosystems of Southeast Asia, or the relatively drier and cooler African forests, this pattern holds true.



Despite their diverse histories and current environmental conditions, the similarity in tree diversity patterns across these regions suggests a possible underlying mechanism governing tree community assembly. This intriguing possibility forms the basis for future research endeavors.



<h2 class="wp-block-heading" id="h-identifying-common-tropical-tree-species">Identifying common tropical tree species</h2>



Another striking aspect of this research is the identification of common tree species. Through statistical analyses and a technique called resampling, the team compiled a list of 1,119 tree species. 



This list, a first of its kind, is expected to significantly streamline future ecological studies by focusing on these common species.



Professor Simon Lewis, the senior author of the study, highlights the novelty of their approach.



"By concentrating on a few hundred common tree species rather than the thousands we know little about, we can unlock new ways to understand these vital ecosystems," Lewis said.



He adds, "This doesn't diminish the importance of rare species, which require special conservation efforts, but emphasizes that significant advancements in knowledge can stem from studying the most common trees."



<h2 class="wp-block-heading" id="h-methodology-and-data-collection">Methodology and data collection</h2>



The research involved assembling data from untouched tropical forests, unaffected by logging or fire. In each location, teams meticulously recorded every tree with a trunk diameter exceeding 10 centimeters within a hectare. 



This colossal effort, led by Professor Lewis over 20 years, resulted in the documentation of 1,003,805 trees, encompassing 8,493 species across almost eight square miles of forest.



In summary, this landmark study shines a light on the uniformity of tree diversity in <a href="https://www.earth.com/news/in-tropical-forests-lightning-strikes-the-most-resilient-trees/" target="_blank" rel="noreferrer noopener">tropical forests</a>, while forging new paths for future ecological research and conservation efforts.



By focusing on the most common species, scientists can gain insights into the overall health and functioning of these crucial ecosystems, ultimately aiding in their preservation for future generations.



The full study was published in the journal <a href="https://www.nature.com/articles/s41586-023-06820-z">Nature</a>.

Scientists name the most common tropical tree species for the first time

In a monumental international effort led by University College London...

Beautiful,Ellery,Lake,And,Mountain,,With,Melting,Snow,Patches,In

Snow, a seemingly simple yet perplexing aspect of our climate, has recently been at the forefront of discussions on global warming. The fluctuating patterns of snowfall and snowpack across the globe have raised crucial questions about climate change and the future of our planet.



Winter seasons in recent years have been marked by contrasting <a href="https://www.earth.com/image/snow-season-arrives-in-the-rocky-mountains/" target="_blank" rel="noreferrer noopener">snow patterns</a>. Regions from Oregon to New Hampshire witnessed a notable lack of snowfall in December, painting a stark picture of a warming world. 



The landscapes, more brown than white, and the severe snow drought in the American Southwest, seemed to signal a dire future.



In stark contrast, record blizzards like those seen in early 2023 have challenged our understanding. These blizzards, which buried <a href="https://www.earth.com/image/powerful-storm-dumps-snow-in-southern-california/" target="_blank" rel="noreferrer noopener">California mountain</a> communities, replenished dry reservoirs, and dropped an astonishing 11 feet of snow in northern Arizona, appeared to contradict the narrative of a warming planet.



<h2 class="wp-block-heading" id="h-scientific-climate-change-data-on-snowpack">Scientific climate change data on snowpack</h2>



The confusion extends to scientific data as well. Ground observations, satellite data, and climate models have shown inconsistent results regarding the impact of global warming on <a href="https://www.earth.com/news/snow-offers-mountain-goats-relief-from-biting-insects/" target="_blank" rel="noreferrer noopener">snowpacks</a> in high-elevation mountains. 



This inconsistency complicates efforts to manage potential water scarcity for many population centers.



Addressing these uncertainties, a recent study from <a href="https://www.dartmouth.edu" target="_blank" rel="noreferrer noopener">Dartmouth</a> provides valuable clarity. The research confirms that seasonal snowpacks across the Northern Hemisphere have significantly <a href="https://www.earth.com/wp-content/uploads/2024/01/climate-change_snowpack-decline_human-driven_map_2m.jpg" target="_blank" rel="noreferrer noopener">diminished over the past 40 years</a>. 



This decline, attributed to human-driven climate change, is most pronounced in certain regions. The Southwestern and Northeastern United States, along with Central and Eastern Europe, have seen snowpack reductions ranging from 10% to 20% per decade.



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



This loss of <a href="https://www.earth.com/news/snow-cover-has-decreased-in-recent-decades/" target="_blank" rel="noreferrer noopener">snowpack</a> has dire implications for hundreds of millions of people in North America, Europe, and Asia who rely on snow for their water supply. 



As first author <a href="https://sites.dartmouth.edu/EEES/graduate-students/alex-gottlieb" target="_blank" rel="noreferrer noopener">Alexander Gottlieb</a>, a PhD student at Dartmouth, points out, "The most immediate and potent risk that climate change poses to society is the loss of the water reservoir stored in snow." 



Gottlieb emphasizes that the study identifies watersheds that have historically lost <a href="https://www.earth.com/news/blowing-snow-plays-an-important-role-in-arctic-warming/" target="_blank" rel="noreferrer noopener">snow</a> and those most vulnerable to future declines. 



He warns of regions like the Southwestern and Northeastern United States approaching near snow-free conditions by the end of March by the end of the 21st century, highlighting the urgency of adapting to water scarcity.



"Our work identifies the watersheds that have experienced historical <a href="https://www.earth.com/news/study-reveals-a-widespread-decline-of-snow-cover-in-the-northern-hemisphere/" target="_blank" rel="noreferrer noopener">snow loss</a> and those that will be most vulnerable to rapid snowpack declines with further warming," Gottlieb said. 



"The train has left the station for regions such as the Southwestern and Northeastern United States. By the end of the 21st century, we expect these places to be close to snow-free by the end of March. We're on that path and not particularly well adapted when it comes to water scarcity."



<h2 class="wp-block-heading" id="h-impact-of-snowpack-decline-from-climate-change">Impact of snowpack decline from climate change</h2>



However, the implications of snow loss extend beyond water security. <a href="https://geography.dartmouth.edu/people/justin-s-mankin" target="_blank" rel="noreferrer noopener">Justin Mankin</a>, an associate professor of geography and the paper's senior author, sheds light on the economic repercussions. 



Regions like the Northeastern U.S., facing steep declines in <a href="https://www.earth.com/news/fall-snow-levels-can-help-predict-a-years-total-snowpack/" target="_blank" rel="noreferrer noopener">snowpack</a>, are at risk of significant economic losses, particularly in states reliant on winter recreation. 



Vermont, New York, and New Hampshire, for example, could see their economies suffer as even <a href="https://www.earth.com/news/artificial-snowmaking-sustainability-must-become-a-priority/" target="_blank" rel="noreferrer noopener">machine-made snow</a> becomes less feasible due to rising temperatures.



Mankin further highlights the disproportionate impact on vulnerable communities. Lower elevation ski resorts, already grappling with decreasing snow, face accelerated challenges. 



Continuation of the trend could lead to the consolidation of skiing activities into larger, more resourced resorts. This shift could have far-reaching consequences on local economies and cultural values.



<h2 class="wp-block-heading" id="h-decoding-snowpack-changes-with-ai">Decoding snowpack changes with AI</h2>



In a world grappling with the effects of global warming, understanding the dynamics of snowpacks is crucial. Gottlieb and Mankin's study, spanning from 1981 to 2020, delved into the changes in snowpack across 169 river basins in the Northern Hemisphere. 



Their focus was on how global warming’s influence on temperature and precipitation patterns has transformed these <a href="https://www.earth.com/image/heavy-snow-cloud-alps/" target="_blank" rel="noreferrer noopener">snowpacks</a>. The loss of snowpacks means potentially less meltwater in spring, affecting rivers, streams, soils, ecosystems, and, importantly, people’s access to water.



The researchers employed a machine learning model to analyze a vast array of data. They examined thousands of observations and climate-model experiments, which included snowpack, temperature, precipitation, and runoff data. 



This innovative approach allowed them to pinpoint where and how warming has led to snowpack losses. Crucially, it also enabled them to study the complex interplay between temperature and precipitation changes -- factors that decrease and increase <a href="https://www.earth.com/news/mountains-face-low-to-no-snow-winters-in-a-warming-climate/" target="_blank" rel="noreferrer noopener">snowpack</a> thickness, respectively.



A key achievement of their study was identifying uncertainties in both models and observations. This understanding allowed them to discover aspects previously overlooked in assessing climate change’s impact on snow. 



Their methodology builds upon a <a href="https://home.dartmouth.edu/news/2021/12/finding-predictability-uncertainty-snow-drought" target="_blank" rel="noreferrer noopener">2021 study</a> by the same researchers, which improved predictions of water availability by leveraging uncertainties in measuring snow depth and defining snow drought.



<h2 class="wp-block-heading" id="h-challenging-common-misconceptions-about-snow">Challenging common misconceptions about snow</h2>



Mankin highlights the complexities surrounding <a href="https://www.earth.com/image/snow-around-the-great-lakes/" target="_blank" rel="noreferrer noopener">snow</a> measurements and their implications for water security. "Snow observations are tricky at the regional scales most relevant for assessing water security," he said. 



"Snow is very sensitive to within-winter variations in temperature and precipitation, and the risks from snow loss are not the same in New England as in the Southwest, or for a village in the Alps as in high-mountain Asia," Mankin continued.



The study reveals a striking dichotomy. About 80% of the Northern Hemisphere’s <a href="https://www.earth.com/image/snow-trails-across-eastern-china/" target="_blank" rel="noreferrer noopener">snowpacks</a>, predominantly in far-northern and high-elevation areas, experienced minimal losses or even expansion in places like Alaska, Canada, and Central Asia. This expansion is attributed to increased precipitation in these colder regions.



Conversely, the remaining 20% of <a href="https://www.earth.com/news/microplastics-found-for-the-first-time-in-antarctic-fresh-snow/" target="_blank" rel="noreferrer noopener">snowpacks</a>, crucial for many major population centers, have seen significant reductions. Since 1981, these snowpack declines have been largely inconsistent due to observational uncertainties and natural climate change variations. 



However, Gottlieb and Mankin observed a consistent annual pattern of snow accumulation decline, leaving these regions increasingly short of new water supplies from snowmelt.



<h2 class="wp-block-heading" id="h-the-snow-loss-cliff-and-its-implications">The "Snow-Loss Cliff" and its implications</h2>



One of the study's most alarming findings is the identification of a "snow-loss cliff." This term refers to a critical temperature threshold (17 degrees Fahrenheit or minus 8 degrees Celsius) beyond which snow loss accelerates, even with modest local temperature increases. 



Many densely populated watersheds, reliant on snow for their water supply, face accelerated <a href="https://www.earth.com/news/snow-cover-in-the-alps-could-soon-be-cut-in-half/" target="_blank" rel="noreferrer noopener">snow losses</a> in the coming decades.



"It means that water managers who rely on snowmelt can't wait for all the observations to agree on snow loss before they prepare for permanent changes to water supplies. By then, it's too late," Mankin warns. 



Manking stresses the need for immediate preparation for permanent changes in water supplies, as waiting for complete observational consensus is too late. Once a watershed crosses the snow-loss threshold, the challenge becomes adapting to enduring alterations in water availability.



"Once a basin has fallen off that cliff, it's no longer about managing a short-term emergency until the next big snow. Instead, they will be adapting to permanent changes to water availability," he explained.



In summary, Gottlieb and Mankin’s study is a critical contribution to our understanding of the complex relationship between climate change and snowpacks. It highlights the urgent need for regions to prepare for and adapt to these changing conditions, ensuring the sustainability of water resources in a warming world.

<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."
