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



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



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



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



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



The changes split the West Coast into two distinct stories. 



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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



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

Study: Most Vulnerable Countries Know Least About Climate Change. Collaborations on climate change research are divided into separate regions of the world with little knowledge exchange between them shows a new Danish-Brazilian study led by the University of Copenhagen. The most vulnerable countries of the world are largely disconnected from the production and flow of scientific knowledge on climate change, leaving their climate policymaking with little contextually relevant advice. The study calls for initiatives across private, governmental and non-governmental organisations, and from researchers themselves to diminish the knowledge gap.

When new research on climate change is published it most often concerns and is produced by the developed countries and the BRICS countries Brazil, India, China and South Africa rather than countries most vulnerable, but less contributing, to climate change.Study: Most Vulnerable Countries Know Least About Climate Change

The little research that does concern developing countries often lacks a locally based author. For instance, only about one fifth of the publications concerning climate change in Africa have a locally based first author - for the developed regions, it is two thirds of the publications. For some countries, such as the Republic of Congo and North Korea with up to 72 relevant publications, there are no locally based authors, not even co-authors.

"Without locally generated knowledge, it is more challenging to provide and integrate contextually relevant advice, and this leaves a critical gap in the climate policy debates. This is particularly worrying as we are dealing with countries likely to experience severe climatic changes and that are most sensitive to its detrimental impacts" says lead-author and postdoc Maya Pasgaard from the Department of Geosciences and Natural Resource Management at the University of Copenhagen.

In total, the study analysed author affiliations of more than 15.000 climate change publications published between 1999 and 2010. Authors focusing on the same countries for climate change research typically share geographical proximity, common climate, politics and economic characteristics.

"The regional divides limit critical flows of experiences and competencies across geographical and political-economic boundaries; a flow which is also needed to tackle the many threats and challenges of comparable character across regions, such as changes in crops, pest management and adaptation to climate hazards," says co-author and Professor Niels Strange from the Center for Macroecology, Evolution and Climate at the University of Copenhagen.

With the exception of some South American and African countries who share research interests, knowledge exchange on climate change suffers from large regional divides, in particular among vulnerable, developing regions.

The study recommends initiatives that focus on strengthening collaborations across geographical distances and across national differences in climate, export, democracy and national economy, as well as strengthening the local production and integration of knowledge.

Co-author and Assistant Professor Bo Dalsgaard from the Center for Macroecology, Evolution and Climate says:

"There is an array of partners responsible for increasing collaborations, ranging from big international organisations, such as the UN, to individual governments and higher education leaders. We also urge individual researchers and private companies alike to take responsibility for increasing cross-national collaborations and thus increase knowledge exchange between regions".

He is personally involved in a collaborative project across geographical, climatic and political-economic boundaries with UNICAMP in Brazil, the University of the West Indies in Jamaica, local coffee growers from, amongst other players, the Jamaican Coffee Growers' Association, and the London-based gourmet coffee brand Oubu Coffee. Together they study the effects of climate on the pollination of coffee in the Blue Mountains of Jamaica, West Indies.

"This project was initiated through a personal network between me, Oubu Coffee and their relations within Jamaica. As researchers we have to be willing to drive the transition forward through such opportunities and networks. Waiting for international institutions or governments to create new initiatives is not the only way forward" says Bo Dalsgaard.

Maya Pasgaard also has experience with research collaboration across regions, working together with a local researcher from Cambodia on community-based forest protection to mitigate climate change.

"Cross-border collaborations are not just highly relevant scientifically, but also rewarding on a personal level, as cultural knowledge exchange becomes an integrated part of the collaboration" she says.

The study is published online in the journal Global Environmental Change.

Arctic OffShore Drilling

Shell Loses $7.4 Billion After Pulling Oil Rigs From The Arctic. Royal Dutch Shell reported a third quarter loss of $7.4 billion Thursday as it re-organized and cancelled projects, including drilling in Alaska, to cope with the plunge in oil prices.
The net loss compares with a profit of $4.5 billion in the same period last year. Shell reported $7.9 billion in charges, including $2.6 billion for Alaska and $2 billion related to the decision to cancel the Carmon Creek project in Alberta, Canada.
Excluding one-time items and fluctuations in the value of inventories, the company said profit dropped to $1.8 billion, from $5.8 billion a year earlier, reflecting the plunge in oil prices.
"Shell's integrated business and our performance drive are helping to mitigate the impact of low oil prices on the bottom line in what is a difficult environment for the industry today," CEO Ben van Beurden said.
Energy companies are struggling to adjust to an age of lower prices after oil dropped to a six-year low in August. Brent crude, the benchmark for North Sea oil, averaged $50.26 a barrel in the third quarter, down 51 percent from a year earlier.
The drop is forcing companies to reconsider the <a href="https://www.bing.com/search?q=economics&amp;cvid=133c0645dcd14603b8c0de3930c2715d&amp;FORM=ANAB01&amp;PC=HCTS">economics</a> of projects.
Shell said it decided to discontinue work on the Carmon Creek thermal oil sands project because it "does not rank in its portfolio at this time."
In Alaska, Shell had intended to access what the U.S. Geological survey estimated to be some 26 billion barrels of conventionally recoverable oil under Arctic waters. But the company's first drilling produced only minor amounts of oil and gas. Shell Loses $7.4 Billion After Pulling Oil Rigs From The Arctic
"This, combined with the current economic and regulatory environment, has led Shell to cease further exploration activity offshore Alaska for the foreseeable future," the company said.
At the same time, environmental activists had the company in its sights, pledging to thwart the company in the arena of public opinion. Protesters argued that industrial activity would hurt fragile ecosystems and marine mammals. They insisted that the icy Arctic waters could not be cleaned in the event of a spill.
Analysts believe the company took the worst of the hit in Thursday's results.
"I think the bulk of the assets has been written off," Fadel Gheit, a managing director and senior analyst at Oppenheimer &amp; Co. Inc., said in an email.
Shell said it would still pay a dividend of 47 cents a share on third quarter earnings.

Scientists: Warming Ocean Is Cause Behind Collapse Of Cod Fishery. The rapid warming ocean off New England is a key factor in the collapse of the region's cod fishery, and changes to the species' management are needed to save one of <a href="https://www.bing.com/search?q=america&amp;cvid=e42be66a61d64b42b9dcfb7ac0da673f&amp;FORM=ANAB01&amp;PC=HCTS">America's</a> oldest industries, according to a report published Thursday in Science magazine.
Fishery managers say cod spawning in the Gulf of Maine - a key fishing area between Cape Cod and Canada that touches Massachusetts, Maine and New Hampshire - is only about 3 percent of sustainable levels, and participants in the fishery that dates to the Colonial era face dramatic quota cuts as a result.
The scientists behind the Science report say the warming of the Gulf of <a href="http://www.earth.com/news/shellfish-are-vanishing-from-the-gulf-of-maine/">Maine</a>, which accelerated from 2004 to 2013, reduced cod's capacity to rebound from fishing pressure. The report gives credence to the idea - supported by advocacy groups, fishing managers and even some fishermen - that climate change has played a role in cod's collapse. Scientists: Warming Ocean Is Cause Behind Collapse Of Cod Fishery
The lead author of the study, Andrew Pershing of the Gulf of Maine Research Institute in Portland, said the gulf is warming at a rate 99 percent faster than anywhere else in the world, and as a result, too many of the fish aren't living past age 4 or 5. Cod can live to be older than 20.
"Every animal has a temperature range that they prefer. The Gulf of Maine, for cod, is really at the warm end of that," Pershing said. "If you warm it, you push it somewhere that's really uncomfortable."
The report comes amid a collapse in commercial catch of Atlantic cod, which are also fished off New England in Georges Bank, where the stock has also collapsed. Catch fell from more than 33 million pounds in 2001 to less than 5 million pounds in 2013.
As a result, the price of local cod has risen in New England. Now, much of the cod in fish and chips there is from places such as Iceland and Norway, and sometimes restaurants use a different species altogether.
David Goethel, a biologist and longtime New Hampshire fisherman, said the study is reflective of what he sees at sea. He said it's important that published science now backs that up.
But he also said fishing managers are trying to rebuild cod stocks to unrealistic levels, which results in low quotas for fishermen. Instead, he said, they should set quotas that reflect the status of the stock. A New England fishing regulatory council voted to reduce the total allowable Gulf of Maine cod catch limit from 1,550 metric tons to 386 metric tons a year ago. In the early 2000s, it was 8,000 metric tons per year.
"We need to manage for what is here now," said Goethel, himself a former member of the fishing regulatory council. "Otherwise, we're just going to leave enormous amounts of protein in the water for no reason, for what's basically a bureaucratic reason."
The report said regulators need to incorporate environmental factors in managing commercial species. Jud Crawford, science and policy manager of U.S. Oceans, Northeast for Pew Charitable trusts, said that could mean placing a premium on conserving cod habitat.
Malin Pinsky, a biology professor at Rutgers University who was not involved in the study, said the findings help explain the northern shift in the cod's population. Researchers reported this month that numbers are improving in the colder waters off Newfoundland and Labrador.
"What we're learning about cod are the same kind of processes that are likely to play out in a wide range of important fish in this and other regions," he said.

A total of eight countries - Canada, Denmark, Finland, Iceland, Norway, Sweden, Russia and the U.S. - are formally establishing the Arctic Coast Guard Forum. The organization will help implement agreements of the Arctic Council, which is comprised of the same member countries, but also make its own decisions and plans concerning Arctic operations.
"Much of the ACGF's work will focus on fostering the strong partnerships required to support safe, secure and environmentally responsible maritime activity in the Arctic region," said Lisa Novak, a Coast Guard spokeswoman in Washington.
As the planet warms, waterways through the Northwest Passage above <a href="https://www.bing.com/search?q=canada&amp;cvid=996103fc3a274ff592c474e6955bfcfc&amp;FORM=ANAB01&amp;PC=HCTS">Canada</a> and Russia have opened during summer months, funneling more ship traffic through the Bering Strait. The region also holds trillions of dollars' worth of oil and gas reserves, and many have warned of a new battleground for resources emerging in the 21st century.
The summit is taking place at the academy's Center for Arctic Study and Policy. Officials say the Arctic has been emerging as a popular topic of study at the academy, where cadets train and study along the Thames River in New London for careers as Coast Guard officers.

Puerto Rico Bans All Plastic Bags. Puerto Rico's governor signed an executive order on Friday banning the use of plastic bags across the U.S. territory, defying legislators who just days ago rejected a similar bill.
The ban will take effect in mid-2016 and will be preceded by a six-month educational campaign, Gov. Alejandro Garcia Padilla said.
The announcement surprised many because 25 legislators in the island's House of Representatives recently voted against a measure calling for such a ban. Lawmakers had said they opposed the bill because it would charge people for the use of plastic bags amid an economic crisis. Puerto Rico Bans All Plastic Bags
Garcia said grocery stores across Puerto Rico import tons of plastic bags a year, noting that one small supermarket chain alone annually imports bags that fit in six boxcars that are 42 feet (13 meters) long.
"All that ends up in landfills in the best-case scenario," he said. "They end up on our streets, in our sewage system ... and kill our turtles and <a href="http://www.earth.com/news/ocean-acidification-could-cause-coral-reefs-to-fall-apart/">coral reefs.</a>"
The popular western tourist town of Rincon is the only Puerto Rican municipality that currently bans the use of plastic bags.
Environmental activists praised the move, noting that it is common to double-bag all groceries on the island, no matter how small the purchase. Garcia said he would push for legislation to be approved to help bolster his executive order.
Elsewhere in the U.S., plastic bag bans have been implemented in cities including Los Angeles, San Francisco, Chicago, Seattle and Austin, Texas. In addition, all counties in Hawaii have approved such a prohibition. There is currently no statewide ban on plastic bags, although California is placing the issue before voters in a November 2016 ballot.

Study: Mass Gains Of Antarctic Ice Sheet Greater Than Losses. A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change’s (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

According to the new analysis of satellite data, the <a href="http://www.earth.com/news/antarctica-is-melting-faster-than-models-predict-due-to-climate-variability/">Antarctic</a> ice sheet showed a net gain of 112 billion tons of ice a year from 1992 to 2001. That net gain slowed   to 82 billion tons of ice per year between 2003 and 2008. Study: Mass Gains Of Antarctic Ice Sheet Greater Than Losses

“We’re essentially in agreement with other studies that show an increase in ice discharge in the Antarctic Peninsula and the Thwaites and Pine Island region of West Antarctica,” said Jay Zwally, a glaciologist with NASA Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the study, which was published on Oct. 30 in the Journal of Glaciology. “Our main disagreement is for East Antarctica and the interior of West Antarctica – there, we see an ice gain that exceeds the losses in the other areas.”  Zwally added that his team “measured small height changes over large areas, as well as the large changes observed over smaller areas.”

Scientists calculate how much the ice sheet is growing or shrinking from the changes in surface height that are measured by the satellite altimeters. In locations where the amount of new snowfall accumulating on an ice sheet is not equal to the ice flow downward and outward to the ocean, the surface height changes and the ice-sheet mass grows or shrinks.

But it might only take a few decades for Antarctica’s growth to reverse, according to Zwally. “If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they’ve been increasing for the last two decades, the losses will catch up with the long-term gain in East Antarctica in 20 or 30 years -- I don’t think there will be enough snowfall increase to offset these losses.”

The study analyzed changes in the surface height of the Antarctic ice sheet measured by radar altimeters on two European Space Agency European Remote Sensing (ERS) satellites, spanning from 1992 to 2001, and by the laser altimeter on NASA’s Ice, Cloud, and land Elevation Satellite (ICESat) from 2003 to 2008.

Zwally said that while other scientists have assumed that the gains in elevation seen in East Antarctica are due to recent increases in snow accumulation, his team used meteorological data beginning in 1979 to show that the snowfall in East Antarctica actually decreased by 11 billion tons per year during both the ERS and ICESat periods. They also used information on snow accumulation for tens of thousands of years, derived by other scientists from ice cores, to conclude that East Antarctica has been thickening for a very long time.

“At the end of the last Ice Age, the air became warmer and carried more moisture across the continent, doubling the amount of snow dropped on the ice sheet,” Zwally said.

The extra snowfall that began 10,000 years ago has been slowly accumulating on the ice sheet and compacting into solid ice over millennia, thickening the ice in East Antarctica and the interior of West Antarctica by an average of 0.7 inches (1.7 centimeters) per year. This small thickening, sustained over thousands of years and spread over the vast expanse of these sectors of Antarctica, corresponds to a very large gain of ice – enough to outweigh the losses from fast-flowing glaciers in other parts of the continent and reduce global sea level rise.

Zwally’s team calculated that the mass gain from the thickening of East Antarctica remained steady from 1992 to 2008 at 200 billion tons per year, while the ice losses from the coastal regions of West Antarctica and the Antarctic Peninsula increased by 65 billion tons per year.

“The good news is that Antarctica is not currently contributing to sea level rise, but is taking 0.23 millimeters per year away,” Zwally said. “But this is also bad news. If the 0.27 millimeters per year of sea level rise attributed to Antarctica in the IPCC report is not really coming from Antarctica, there must be some other contribution to sea level rise that is not accounted for.”

“The new study highlights the difficulties of measuring the small changes in ice height happening in East Antarctica,” said Ben Smith, a glaciologist with the University of Washington in Seattle who was not involved in Zwally’s study.

"Doing altimetry accurately for very large areas is extraordinarily difficult, and there are measurements of snow accumulation that need to be done independently to understand what’s happening in these places,” Smith said.

To help accurately measure changes in Antarctica, NASA is developing the successor to the ICESat mission, ICESat-2, which is scheduled to launch in 2018. “ICESat-2 will measure changes in the ice sheet within the thickness of a No. 2 pencil,” said Tom Neumann, a glaciologist at Goddard and deputy project scientist for ICESat-2. “It will contribute to solving the problem of Antarctica’s mass balance by providing a long-term record of elevation changes.”

French President Goes To China To Boost Climate Negotiations. French President Francois Hollande hopes to use a state visit to China to boost difficult climate negotiations a month before a U.N. conference in Paris aimed at slowing global warming.
<a href="http://www.earth.com/image/historic-flooding-has-killed-hundreds-across-china/">China</a>, the most populous country and the biggest emitter of climate-warming greenhouse gases in the world, has promised it will try to cap its rising emissions before 2030 as part of its national pledge ahead of the <a href="https://www.bing.com/search?q=paris&amp;cvid=9393f8619ea54c7fb2d557aafaad6221&amp;FORM=ANAB01&amp;PC=HCTS">Paris</a> conference. French President Goes To China To Boost Climate Negotiations
Hollande says he intends to launch a bilateral appeal with Chinese President Xi Jinping "to make the climate conference a success." France is notably trying to get China's approval of a mechanism that would require countries to step up their emissions cuts over time.
This would be "a key" to success of the U.N. climate talks, a French diplomatic official said, because the current national pledges won't be enough to achieve the goal of keeping the rise in global temperatures below 2 degrees Celsius (3.6 degrees Fahrenheit) between pre-industrial times and the end of the century.
China has "a leading role" in influencing other developing countries on this issue, the diplomat said. France is proposing to update those emissions targets automatically every five years, but the rules have yet to be defined. The official spoke anonymously because discussions on the content of the French-Chinese bilateral declaration were still ongoing.
On Monday, the French president will visit Chongqing in southwest China, where he'll see examples of the country's efforts toward more environmentally friendly technologies. Later in the day, he'll be heading to Beijing to meet with the Chinese president.
On Tuesday, Hollande will meet with Prime Minister Li Keqiang and they will speak to a French-Chinese economic forum on green growth. Hollande will then go to South Korea for a one-day visit.
The Chinese president is expected to come to France on Nov. 30 for the opening of the U.N. climate conference along with many other world leaders, including President Barack Obama. The conference runs through Dec. 11.

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



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



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



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



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



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



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

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



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



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



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

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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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

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



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



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



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



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

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



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



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



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



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



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

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



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



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



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

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



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



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



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



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



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



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



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



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

Today’s Video of the Day from <a href="http://www.ntu.edu.sg/">NTU Singapore</a> reveals that some plants can remove toxic heavy metals from soil.&nbsp;



The researchers analyzed samples of various tropical plant species to test for levels of heavy metals and metalloids. The study showed that there are existing plants with high levels of these contaminants, which means that these species are great candidates for drawing pollutants out of the soil.&nbsp;



Among the plants examined in the study, 12 species had accumulated several types of heavy metals and metalloids. These plants are widely available, including species that are native to Singapore.



“In a small nation like Singapore, land may be repurposed to support new development plans, so it is important that we have a green and sustainable way to remediate land that is contaminated," said Professor Lam Yeng Ming.



"We set out to uncover how to better make use of tropical plants to do phytoremediation and through advanced characterization techniques, we showed how some of these tropical plant species can be an environmentally friendly and literally a 'green' way to remove contaminants in soil."&nbsp;



"Phytoremediation also has benefits of cost effectiveness, simplicity of management, aesthetic advantages, and long-term applicability and sustainability. The strategy prevents erosion and metal leaching by stabilizing or accumulating heavy metals, so that helps reduce the risk of contaminant spread.”

Today’s Video of the Day from the <a href="https://www.acs.org/">American Chemical Society</a> describes why herbicides are not as effective in killing weeds anymore. In the 20th century, chemical companies developed thousands of herbicides. The most commonly used herbicide was glyphosate, which was introduced in 1974.



Over the past few decades, dozens of species of weeds have evolved resistance to glyphosate. Depending on the site of action, the part of the plant that an herbicide interacts with, weeds may even be resistant to herbicides that have not been developed yet.&nbsp;



With increasing resistance to glyphosate and other herbicides, weeds are - once again - becoming a major concern for farmers.&nbsp;

Today’s Video of the Day from the <a href="https://www.jpl.nasa.gov/">NASA Jet Propulsion Laboratory</a> (JPL) describes a dust storm on Mars that was nearly twice the size of the United States. As the storm covered the southern hemisphere of the planet, some of NASA’s explorers had to delay their normal activities.



NASA’s Insight lander put itself in a "safe mode" for 11 days to conserve battery power because solar power was disrupted by the dust. The Ingenuity Mars Helicopter postponed flights until conditions improved.



"A fleet of NASA orbiters monitor Martian dust storms like this one and serve as lifelines to Earth by relaying data from the rovers and lander on the ground back to the team. This includes the Mars Reconnaissance Orbiter, MAVEN, and Odyssey," reports JPL.



"Dust storms like this recent one start close to the ground and are spread by wind as they rise – warming the cold Martian atmosphere."



The images in the video were captured by NASA’s Curiosity as the dust rolled in. A fleet of orbiters monitored the dust storm from above, relaying data from Mars’ explorers back to scientists on Earth.

Today's Video of the Day from the <a href="http://www.esa.int/">European Space Agency</a> features Qeshm Island in the Strait of Hormuz. This strait provides the only sea passage from the Persian Gulf to the open ocean.



Qeshm is separated from the Iranian coast by the Clarence Strait, also known as Khuran.&nbsp;The Hara Forest Protected Area is a network of shallow waterways and forest located between the island and the mainland. This protected region is home to sea turtles, snakes, and more than 150 species of migrating birds.



Qeshm is famous for its wide range of&nbsp;ecotourist&nbsp;attractions, such as the&nbsp;Hara marine forests. According to environmentalists, about 1.5 percent of the world birds and 25 percent of Iran's native <a href="https://www.earth.com/news/female-hummingbirds-avoid-sexual-harassment-by-looking-like-males/">birds</a> annually migrate to the forests, which are the first national geo park in Iran.



Tourists are also drawn to the island to see an age-old Portuguese&nbsp;fort, historic mosques, the&nbsp;Seyyed Mozaffar&nbsp;and&nbsp;Bibi Maryam&nbsp;shrines, and the "Valley of Stars."



The average temperature on the island is 81 degress and the region is often hot and humid. From June to August, the island is described as being oppressively hot. The ideal time to visit is during the winter season.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> features Inhambane Bay in southeast Mozambique.&nbsp;



"Inhambane Bay is a deep inlet into which the small Mutamba River flows," says ESA. "On one side of the bay lies the historical city of Inhambane, capital of the Inhambane Province, while the sister city of Maxixe, the economic capital of Inhambane, sits across from it. The province is the second largest grower of cashews, after Nampula, and it also produces coconut and citrus fruits."



The beaches of Barra and Tofo are popular with tourists. There are also coral reefs along the long coastline of Inhambane, making it an ideal destination for scuba diving and snorkeling.



"Mozambique’s extensive coastline heightens the country’s vulnerability to tropical cyclones that develop in the Indian Ocean as well as storm surge flooding," says ESA.



"More than half of the population lives in low lying coastal areas, putting communities at risk. Inhambane Bay was dangerously close to where Cyclone Idai made landfall in 2019 causing widespread destruction to the country."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency </a>&nbsp;features the Kangerlussuaq Glacier, one of the largest tidewater outlet glaciers in Greenland. The glacier is located on the east coast of the Greenland ice sheet.



As human-induced climate change continues to drive up temperatures, global ice loss is accelerating at an alarming rate. ESA reports that, over the past decade alone, 3.5 trillion tons of ice have melted from the Greenland ice sheet. This is enough to cover the UK with meltwater 15 meters deep.



Based on satellite imagery, researchers determined that Kangerlussuaq entered a new phase of rapid retreat and acceleration in 2017. In their study, published in <a href="https://www.frontiersin.org/articles/10.3389/feart.2019.00123/full">Frontiers in Earth Science</a>,&nbsp; the experts report that the glacier's ice front is now at its most retreated position since the early 20th century.



"Given Kangerlussuaq’s previous impacts on both the magnitude and pattern of ice sheet wide mass loss, we predict that its new phase of retreat, acceleration and thinning will markedly enhance the south-east region’s contribution to increasing discharge from the ice sheet," wrote the study authors.&nbsp;&nbsp;



"More broadly, accurate forecasting of the ice sheet’s contribution to sea level rise will require a deeper understanding of, and responses to, these non-linear ice dynamic processes."

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the complex relationship between ocean and climate. ESA's Climate Change Initiative will help us understand how oceans influence the climate and how climate change is impacting the oceans.&nbsp;



"Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate," explains ESA.



"As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life."



The amount of heat and carbon dioxide soaked up by the ocean depends on specific variables, including phytoplankton, temperatures, waves, salinity, and ice cover. Satellites can be used to measure these variables from space.



"From their unique vantage point, satellites provide key information for understanding the complexities of our planet and monitoring environmental issues," says ESA.

Today’s Video of the Day from the <a href="https://www.esa.int/">European Space Agency</a> describes the importance of monitoring the shape of the sea surface, which is constantly changing. These observations have many applications, such as ship routing, <a href="https://www.earth.com/news/the-modem-ocean-is-a-tough-place-for-whales-to-survive/">ocean</a> current forecasting, and debris tracking.



"A project supported by the Discovery element of ESA’s Basic Activities recently investigated a new technique to measure sea surface topography very precisely," reports ESA.



"The technique involves looking at satellite navigation (GNSS) signals that have been reflected off of the sea surface at very low angles. At these so-called grazing angles, waves and surface roughness have very little impact on the reflection process; the sea surface acts as a very smooth mirror."



Estel Cardellach is the principal investigator at the Institute for Space Studies of Catalonia, who first submitted the idea for the project.



“In a mirror-like reflection the phase of the signal can be tracked – it is continuous," said Cardellach. "Different surface heights result in different phase measurements. It gives a very precise measurement of the surface altitude at a few centimetres’ precision.”



The researchers developed a GNSS receiver and set up an experiment in the Balaeric Islands to collect signals from the receiver that were reflected off the sea surface. Ultimately, these signals will provide improved measurements of the shape of the sea surface.

Today’s Video of the Day from <a href="https://www.nasa.gov/goddard">NASA’s Goddard Space Flight Center</a> describes how scientists are using autonomous sound sensors to monitor deforestation in the Amazon. By recording soundscapes, the experts can determine which animals are present through their distinct sounds.&nbsp;



Using this method, sounds can be used as scientific measurements to analyze the effects of deforestation. The researchers will gain a better understanding of how the acoustics of a forest can be used to measure its health.&nbsp;



"From space, parts of the Amazon rainforest that have previously been logged or burned may look lush and green, like a place buzzing with activity and full of sounds. But inside the rainforest, the animal life may tell a different story, of a harsh environment and a quieter soundscape," says NASA.
