							<![CDATA[Sea ice floating atop the Arctic Ocean reached its minimum extent for 2025 on Sept. 10, covering 4.602 million square kilometers (1.78 million square miles) concluding this year’s summer melt-out. That’s far from a record low and represents a recovery, in some ways, from where things stood earlier this year. At the winter maximum in March 2025, the Arctic ice was in bad shape. That’s the month in which sea ice, encouraged by freezing temperatures and 24-7 darkness, annually reaches its greatest extent. Ice cover in the region then barely topped 14.3 million square kilometers (5.5 million square miles) — the smallest extent at the winter maximum observed in the 47-year satellite record, and more than 1 million km2 (386,000 mi2) below the 1981 to 2010 average winter maximum. Much of 2025 followed a similar downward sloping path; throughout June and into early August, Arctic sea ice cover was tracking close to, if not at, a record low for the time of year. But things swung around in the latter half of August, as ice melt stagnated. “You get to August and the sun is setting in the Arctic, so things start to slow down,” said Walt Meier, a senior research scientist with the National Snow and Ice Data Center (NSIDC) in Colorado. “You need a lot of momentum to keep going, some kind of unusual winds or a big storm like we had in 2012,” the record low sea ice minimum year. “We haven’t really seen that this summer.”&hellip;This article was originally published on <a href="https://news.mongabay.com/2025/09/no-new-record-low-for-arctic-sea-ice-loss-in-2025/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Sea ice extent is at record, and near record, lows for this time of year in both polar regions, leaving the planet increasingly vulnerable to the cascading effects of global warming. This March, the Arctic sea ice winter maximum reached its lowest extent in the 47-year satellite record, while the Antarctic sea ice summer minimum vied for the second lowest recorded extent in nearly five decades, according to data from the U.S. National Snow and Ice Data Center (NSIDC). With less sea ice to reflect solar radiation, and more open ocean to absorb and store heat, the polar cooling system that helps protect the planet from higher temperatures will increasingly become dysfunctional. Recent climate models predict daunting scenarios of irreversible ecosystem change at Earth’s poles, with those drastic changes in polar regions rippling out to impact the rest of the world. “The Arctic and the Antarctic are really different systems, but anthropogenic global warming is the overall factor that’s leading to less ice in the north and the south,” said Walt Meier, an NSIDC senior research scientist.

							<![CDATA[Earth’s frozen places — ice sheets, glaciers and permafrost — are melting: A clear sign of climate change and a planet quickly exiting the stable state that gave rise to human civilization. This great thaw is having far-reaching consequences for communities and individuals across the globe — from polar and mountainous regions to coastal areas. In a recent landmark report, marking the World Day for Glaciers, UNESCO is ringing alarm bells: Cryosphere melt is putting freshwater accessibility at risk for more than one billion people living in mountainous regions and a further two billion living downstream as glaciers and snowpacks melt away and decline; most of those individuals live in developing countries. That same report finds that cryosphere melt is endangering two-thirds of irrigated agriculture across the globe. “The melting and the changes in the cryosphere are a reality and we need to really start taking action,” Abou Amani, director of the Division of Water Sciences and secretary of the Intergovernmental Hydrological Programme, tells Mongabay in an interview. That’s a stark warning, but only the tip of the iceberg when it comes to gauging the cryosphere’s importance to human wellbeing and evaluating potential harms as it shrinks away. Amani lists the ever-increasing risks associated with shrinking mountain snowpacks and glaciers — melting that has downstream impacts on water quality and availability, harms food security, heightens disease risk, triggers catastrophic landslides and glacial lake outburst floods (or GLOFs), and threatens the long-term viability of hydropower. Those risks have already heightened —&hellip;This article was originally published on <a href="https://news.mongabay.com/2025/03/with-climate-change-cryosphere-melt-scales-up-as-a-threat-to-planetary-health/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[The Arctic region has shifted from storing carbon dioxide to releasing it into the atmosphere, according to the 2024 Arctic Report Card released by the U.S. National Oceanic and Atmospheric Administration. The report, authored by 97 scientists from 11 countries, documents widespread changes across the Arctic, from declining caribou populations to record-breaking temperatures. Scientists say this rapid warming is reshaping the region&#8217;s environmental and human systems. &#8220;It&#8217;s not particularly surprising, although it&#8217;s still really sobering,&#8221; Twila Moon, deputy lead scientist at the National Snow and Ice Data Center at the University of Colorado Boulder and an editor of this year&#8217;s report, told Mongabay. The Arctic is Earth&#8217;s northernmost region, centered around the Arctic Ocean and surrounded by the lands of North America, Europe and Asia. The treeless tundra that rings the Arctic Ocean covers an area nearly twice the size of Alaska. This region has historically served as Earth&#8217;s freezer. Its permanently frozen ground, called permafrost, stores more than half of all the carbon stored in the Earth’s soil, which has accumulated over thousands of years. This map shows the Arctic&#8217;s average carbon balance from 2002-2020. Land areas colored purple were a source of carbon dioxide to the atmosphere. The darkest purple clusters show areas where there were large releases due to wildfires. Green areas had a negative carbon dioxide flux, meaning they were a “sink” that removed and stored atmospheric carbon dioxide.

							<![CDATA[For sea ice scientists, September is the time for polar highs and lows. Around mid-month, the Antarctic winter sea ice approaches its highest extent, while the Arctic summer thaw melts the region’s sea ice to its lowest extent. This year, Antarctic sea ice is shrinking to new winter lows for the second year in a row, with only 17.15 million km2 (6.62 million mi2) remaining on September 19, according to satellite records analyzed by the U.S. National Snow and Ice Data Center (NSIDC). This drop is almost one million km2 (roughly 400,000 mi2) less than the typical mid- September mean of about 18.5 million km2 (about 7.1 million mi2). But scientists say it may still be too soon to declare the winter sea ice annual maximum extent. In the Arctic this year, sea ice continues its multidecade downward slide, with just 4.28 million km2 (1.65 million mi2), making it the 7th lowest minimum in the satellite record, based on the NSIDC 5-day average extent. Polar researchers want to know: Is sea ice decline the new normal? “That&#8217;s the big question,” said Walt Meier, a sea ice expert with the NSIDC. “Is the Antarctic sea ice finally responding to global warming? Or is this just an extreme year or two?” Melting sea ice in the Arctic Ocean’s Canada Basin. Image courtesy of Jeremy Potter/NOAA.

							<![CDATA[July is the peak of melt season in the Arctic. The sun is high and shines for almost 24 hours a day. Air and water temperatures rise above freezing. Rapid midsummer melt is therefore both unremarkable and unsurprising. But it is also an unreliable indicator of just how much ice will cover the Arctic Ocean when the September annual sea ice minimum arrives. Now a combination of satellite and on-the-ice observations are helping scientists better understand summer sea ice behavior and track the evolution of melt ponds atop the ice, so as to more accurately forecast what extent will remain frozen at the September minimum. In separate research, scientists have recently demonstrated how to see details on sea ice, combining high- and low-resolution satellite images to get a clearer picture of melt ponds and thereby test how well climate models are capturing melt pond evolution. Scientists study Arctic melt pond evolution. Image courtesy of Melinda Webster, University of Washington. Uncovering melt ponds with satellites Ice and snow reflect sunlight, keeping the Arctic cool, while large dark areas of open ocean absorb abundant solar energy, which triggers more ice melt and delays the autumn refreeze. Melt ponds sitting atop the sea ice absorb more energy than fresh snow, but less than open water. So, understanding their evolution could help scientists better forecast future seasonal sea ice extent. But melt ponds have always been hard to see — especially on satellite images. Passive microwave data can’t distinguish between melt ponds and open&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/08/arctic-melt-ponds-influence-sea-ice-extent-each-summer-but-how-much/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[For a few days each June, the saltwater wind that blows over the fairgrounds in Utqiagvik, Alaska mixes with the smell of coffee, salmonberry pie and fresh whale meat. The festivities start early and end under the midnight sun during Nalukataq, the annual whaling festival. By noon, the tables at the center of the fairgrounds are filled with slabs of whale blubber, cauldrons of stew and baked goods — enough to feed the town for a month. After a prayer, crew members circle the fairgrounds and fill coolers with food. Meanwhile, captains trade turns making speeches, pumping up the crowd and singing songs into a megaphone. On the first day of last summer’s festival, one cut of whale meat was conspicuously absent from the spread. The kidneys of a bowhead whale (Balaena mysticetus), which are usually slow cooked through the morning, were sitting in wildlife veterinarian Raphaela Stimmelmayr’s laboratory eight kilometers (five miles) away at the North Slope Borough Department of Wildlife Management.

							<![CDATA[Dozens of once-pristine rivers and streams in Alaska&#8217;s Brooks Range are turning an alarming shade of orange. The discoloration, according to a new study published in the journal Communications Earth and Environment, is likely caused by the thawing of permafrost, which is exposing previously frozen minerals that are now leaching into the waterways. The research team, led by ecologist Jon O&#8217;Donnell from the U.S. National Park Service, documented 75 locations across a vast area of northern Alaska where the crystal-clear waters now appear heavily stained. Using satellite imagery and field observations, the scientists determined that the onset of this discoloration coincided with a period of warming and increased snowfall in the region over the past decade. Permafrost, which is ground that remains frozen year-round, acts as a storage vault for various minerals. As rising temperatures cause this frozen layer to thaw, these minerals are exposed to water and oxygen, triggering chemical reactions that release iron and other metals into the groundwater. This metal-rich water then makes its way into rivers and streams. &#8220;Our recent study highlights an unforeseen consequence of climate change on Arctic rivers,&#8221; study co-author Brett Poulin, an environmental toxicologist from the University of California, Davis, told Mongabay. &#8220;Arctic environments are warming up to four times faster than the globe as a whole, and this is resulting in deterioration of water quality in the most pristine rivers in North America.&#8221; Map of orange stream observations across Arctic Inventory and Monitoring Network (ARCN) parks in northern Alaska.

							<![CDATA[Most of us will never travel to Earth’s poles, but every creature on this planet will likely experience the consequences of escalating global warming in the polar north and south. Rapidly rising temperatures are radically altering the freezing, melting and precipitation patterns in the polar regions. And there’s strong evidence those changes don’t stay in the Arctic or Antarctic, but resonate across the world. Scientists now know that events in the far north and south affect global weather, sea level rise, biodiversity, ocean currents and more. Three recent studies add new insights about the effects of warming in the coldest places on Earth — and, by extension, on all of us. Aerial view of a permafrost thaw slump on Herschel Island (Nunataryuk project), Unorganized Yukon, Canada. Arctic permafrost can store greenhouse gases for many centuries, but when that permafrost melts it releases those gases and they add to global climate change.

Arctic shifting from greenhouse gas sink to source For centuries, the Arctic landscape has been a reliable long-term repository for greenhouse gases that, if released in large amounts into the atmosphere in coming years, could significantly accelerate global warming. But since the late 1970s, the Arctic has warmed at least twice — and perhaps almost four times — as fast as the rest of the world, leading to more thawed permafrost, raging record wildfires, and drastic terrain alterations. In March 2024, scientists released a new study of this changing landscape that&hellip;This article was originally published on <a href="https://news.mongabay.com/2024/05/polar-warning-warming-temperatures-mean-more-than-melted-ice/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Warming temperatures in the Arctic are accelerating the thaw of carbon-rich permafrost and threatening to add massive amounts of carbon dioxide and methane to an atmosphere already overheating from the buildup of anthropogenic greenhouse gas emissions. More than half that permafrost lies beneath remote Russian soil, where scientists have long worked in an international research community that freely shared its field stations, climate sensors and data sets to better understand the rapidly changing polar region’s planetary impacts. Researchers are especially eager to know when a dangerous tipping point may be reached that would trigger the release of vast amounts of greenhouse gases stored in frozen soils. But then came the Russian invasion of Ukraine on Feb. 24, 2022, and all that cooperation came to a halt, part of the fallout of Western sanctions on Russia. Since then, international researchers outside Russia have applied creative workarounds in order to continue their research, but problems remain. “If you haven&#8217;t seen or touched or smelled permafrost, it’s challenging to talk with people about it,” says Guido Grosse, a geologist at Germany’s Alfred Wegener Institute. In fact, people living on permafrost don’t always know it, as it can be hidden below the soil surface. To make permafrost more “real,” Grosse often brings permafrost samples to presentations for people to touch. Image courtesy of bradosav via Flickr (CC by 2.0).

							<![CDATA[KATHMANDU — The South Col in the Sagarmatha (Mount Everest) region faces blasts of unrelenting winds that sweep away almost everything in their path, including snow. Located nearly 8,000 meters (26,000 feet) above sea level, the southeastern ridge of this desolate terrain is where mountaineers heading to world&#8217;s tallest peak make their final camp. A recent study published in the journal Arctic, Antarctic, and Alpine Research, shows that even the winds haven’t swept away a trail of tough microbes that can survive the harsh conditions on the Roof of the World for decades, if not centuries, left behind by mountaineers in the area. “Some of the microbes we found were possibly transported by humans when they sneeze or cough,” said Steve Schmidt, co-author on the paper and professor of ecology and evolutionary biology. “The concern, with all the pollution that’s going on Everest, is that these microbes aren’t going to go away,” he told Mongabay, adding that he himself didn’t go to Sagarmatha to collect soil samples there. Through his previous work, Schmidt had established ties with researchers on their way to Sagarmatha to set up the world&#8217;s highest weather station on South Col in May 2019 as part of the National Geographic and Rolex Perpetual Planet Everest Expedition (April to May 2019).  He requested collections of soil samples, to which Baker Perry, co-author and professor of geography at Appalachian State University, obliged.

							<![CDATA[JAKARTA — Tropical forest loss remained consistently high in 2021 with no sign of slowing down, despite commitments by companies and governments to curb deforestation, according to new data from the University of Maryland. The data, available on the Global Forest Watch platform managed by the World Resources Institute (WRI), show that tropical countries lost 11.1 million hectares (27.5 million acres) of tree cover in 2021, an area the size of Cuba. Of this total tree loss, 3.75 million hectares (9.3 million acres) occurred in tropical primary forests, the world’s most biologically diverse ecosystems. This means the planet is not on its way to halting and reversing forest loss by 2030, as pledged by 141 countries during last year’s COP26 climate summit in Glasgow, experts say. A handful of countries, most notably Indonesia and Gabon, saw their rates of primary forest loss decline significantly in recent years. But this was offset by high deforestation rates in other tropical countries, such as Brazil and Bolivia. As a result, the tropics still lost 10 football pitches of primary forest per minute in 2021, in the process releasing 2.5 billion metric tons of greenhouse gases (GHG). That’s equivalent to the annual fossil fuel emissions from India. While the tropics lost 11% less primary forest in 2021 than in 2020, the figure was still almost the same as in 2019. This means that loss of primary tropical forests remains “stubbornly persistent throughout the years,” said Rod Taylor, the global director of WRI’s forests program.&hellip;This article was originally published on <a href="https://news.mongabay.com/2022/04/2021-tropical-forest-loss-figures-put-zero-deforestation-goal-by-2030-out-of-reach/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Arctic sea ice extent July 9, 2020. Image courtesy of University of Bremen. The record-setting heat wave that swept through Arctic Siberia in June has yielded a wide-range of deleterious effects in the expansive polar and sub-polar region, triggering raging wildfires, thawing permafrost, and now, spurring the rapid melt-out of Arctic sea ice. Last month, Siberian temperatures spiked, reaching a record average more than 5 degrees Celsius (9 degrees Fahrenheit) hotter than normal, according to recently released data from the European Union. The remote town of Verkhoyansk in northeast Siberia recorded a reading of more than 38 degrees Celsius (100 degrees Fahrenheit) on June 17, the highest temperature ever recorded north of the Arctic Circle. Under this metaphorical blow torch, ice extent in the seas that border Siberia has plummeted in recent days, pushing the Arctic region as a whole into the record books. Between July 2 and July 7, sea ice extent across the Arctic Ocean went from being at its fifth lowest extent for this time of year since satellite record-keeping began in 1979, melting into first place, slightly below even the calamitous year of 2012 which eventually saw sea ice hit a record low at the end of the summer melt season in September. As of July 9, sea ice extent in the global Arctic sits at just 8.310 million square kilometers (3.2 million square miles). If that melting momentum carries forward (and nobody knows if it will), 2020 could nab the title of the lowest ice&hellip;This article was originally published on <a href="https://news.mongabay.com/2020/07/siberian-heat-drives-arctic-ice-extent-to-record-low-for-early-july/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Small scale permafrost slump. Photo credit: NPS Climate Change Response on Visual Hunt / CC BY. The cracked, buckling road between Fairbanks and Fox, Alaska, wends its way past snowy forests where slender birches and black spruce trees protrude out of the ground at impossible angles, slanting and swaying as if the very earth were alive. Scientists call these “drunken forests.” The ground here consists of permafrost — soil, sediment, rock and ice that often remains at or below 0 degrees Celsius (32 degrees Fahrenheit) year-round. Permafrost covers approximately 22.8 million square kilometers (8.8 million square miles) in the Arctic, sub-Arctic and alpine regions — comprising nearly a quarter of the exposed land surface in the northern hemisphere. In Alaska, 85 percent of the state lies within the permafrost zone, though discontinuous permafrost — areas with patchy permafrost presence — underlies much of the Fairbanks area. In Arctic regions, permafrost temperatures often dip down to -8 degrees C (-17.6 degrees F). But in Fairbanks, which lies roughly 321 kilometers (200 miles) south of the Arctic Circle, temperatures hover much closer to the freezing point, causing the permafrost to sporadically thaw out. This freeze-thaw action has long posed challenges for natural and human systems, intoxicating forests, breaking pavement, sinking houses, and even sometimes draining lakes sitting atop it. But as climate change heats up the planet, with the Arctic warming at twice the rate of the rest of the globe, things are about to get a whole lot worse.

							<![CDATA[An open-air market in Marrakesh, Morocco. The city is hosting November’s COP22 Climate Conference and decisions made there could shape its future. If the rising heat brought by global warming isn’t abated, then parts of North Africa could become inhabitable by mid-century, according to a 2016 study. Feliciano Guimarães licensed under the Creative Commons Attribution 2.0 Generic license The first question I ask officials heading to Marrakesh, Morocco for this November’s United Nations Climate Summit known as COP22: How do you top Paris? “There is a lot of political momentum coming from Paris,” answers Dan Bodansky, a climate adviser to the White House and a law professor at Arizona State University. “But will it actually lead to a dynamic where there are changes on the ground in terms of what countries are actually doing?” That is exactly the sort of nuts-and-bolts pragmatic role negotiators hope COP22 will play après Paris. The Paris Agreement is without question an historic achievement. World leaders authored the first-ever blueprint to broadly tackle climate change. The agreement was ratified globally with unprecedented haste and achieves the force of law this week, on November 4th, four years earlier than anticipated. Meanwhile, more than 100 countries, including the U.S., China and India, agreed last month to dramatically limit the future use of hydroflourocarbons, a potent greenhouse gas used in air conditioners. Another climate victory was hailed. But those headed to COP22 will emphatically tell anyone listening: Folks, we’re not there yet. We’re not even close.

							<![CDATA[Undercover sting by Greenpeace exposes two prominent skeptics [The Guardian] Posing as consultants to fossil fuel companies, Greenpeace was able to uncover two prominent climate skeptics that were available for hire to write reports that would cast doubt on the dangers of global warming. Up to a quarter of Alaska’s permafrost could melt by 2100 [Guardian UK] So what’s the big deal with thawing soil? This permafrost, soil that’s been frozen for thousands of years, has been storing pools of carbon. As the permafrost begins to thaw, carbon and methane is released, thereby fueling more warming and melting, which in turn accelerates the warming of our climate even more. Affects from climate change has islanders pleading for help [Reuters] As rising sea levels and tidal waves wash away the coastlines of Maldives islands, the residents are asking for insurance to help cover the costs of the damage. There are some insurance options for other extreme weather losses, such as high waters and flooding, but not for costal erosion.

							<![CDATA[Climate change is happening and humans are causing it, primarily from the increase in atmospheric carbon dioxide caused by burning fossil fuels. This much we know. The &#8220;secret&#8221; comes from changes happening in the fast-warming Arctic: we may be surprisingly close to an Earth that supports far fewer humans than it does today. Permafrost and methane hydrates In the Arctic, two things may become crucial: permafrost and methane hydrates. Permafrost&#8212;ground frozen for thousands of years&#8212;is a huge store of carbon, originating from long-dead plants and animals. As permafrost thaws, this carbon is released into the atmosphere as carbon dioxide or methane, both greenhouse gases that cause climate change. According to a NASA research report, &#8220;Is a Sleeping Climate Giant Stirring in the Arctic?&#8221; there is four to five times the amount of carbon in the permafrost than the sum total of all carbon humanity has emitted into the atmosphere since 1850. Methane hydrate. Photo by: Wusel007/Creative Commons 3.0. Methane doesn&#8217;t last as long as carbon dioxide in the atmosphere. But on a 20-year time scale, it&#8217;s 105 times as potent in causing global warming. In the Arctic Ocean, there is an immense amount of methane stored in ice, in a form called methane hydrates. According to a March 2010 report in Science, these methane hydrates are equivalent to 3-30 times the total amount of carbon dioxide humanity has emitted since the Industrial Revolution. Permafrost and methane hydrates are pivotal because the Arctic (and Antarctic) is warming faster than anywhere else&hellip;This article was originally published on <a href="https://news.mongabay.com/2014/05/climate-changes-ominous-secret/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Frost crystals at the entrance of Ledyanaya Lenskaya Cave. Photo by: Vladimir V. Alexioglo. While nations around the world have committed to keeping temperatures from rising 2 degrees Celsius (3.6 degrees Fahrenheit) above the pre-industrial era, new research published in Science suggests that the global climate could hit a tipping point at just 1.5 degrees Celsius (2.5 degrees Fahrenheit). Studying cave stalactites and stalagmites in Siberia, scientists found that at about 1.5 degrees Celsius the Siberian permafrost melts, potentially releasing a greenhouse gas bomb of 1,000 giga-tonnes, according to some experts. Turning to cave formations&#8212;stalactites and stalagmites&#8212;to reconstruct past climates in Siberian Russia, the scientists found that Russia had little permafrost around 400,000 years ago when the world was about 1.5 degrees warmer than the past 10,000 years (or the length of human civilization). &#8220;The stalactites and stalagmites from these caves are a way of looking back in time to see how warm periods similar to our modern climate affect how far permafrost extends across Siberia,&#8221; lead author Anton Vaks of Oxford University&#8217;s Department of Earth Sciences explains. The stalactites and stalagmites do not grow under permafrost conditions, but only when ice melt or rain is available. Therefore these cave formations act as signals for what past climate looked like. According to the study, the only time the permafrost melted in the last half million years was between 424,000 and 374,000 years ago when temperatures globally hit the 1.5 degree Celsius mark. So far global temperatures have risen 0.8 degrees&hellip;This article was originally published on <a href="https://news.mongabay.com/2013/02/rise-in-1-5-degrees-celsius-likely-to-spark-massive-greenhouse-gas-release-from-permafrost/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Methane, a greenhouse gas 30 times more potent than carbon, is spewing from what was believed to be an impermeable barrier in Siberia in amounts equal to methane releases from the world&#8217;s oceans. The discovery has lead researchers to fear the possibility of abrupt climate warming. According to the study published in Science, subsea permafrost below the East Siberian Arctic Shelf has become compromised, leaking vast amounts of methane into the atmosphere. The researchers have estimated that 6.5 to 10 teragrams of methane is emitted from the East Siberian Arctic Shelf every year: one teragram equals about 1.1 million tons. However, researchers are particularly worried about the amount of methane that could be released in the future. The sea surface above the East Siberian Arctic Shelf is full of ice and bubbles. Sonar is the only way to detect the vast clouds of methane bubbles rising from the sea floor. Photo courtesy of Igor Semiletov, University of Alaska Fairbanks. &#8220;Our concern is that the subsea permafrost has been showing signs of destabilization already,&#8221; explains lead author Natalia Shakhova, a researcher at the University of Alaska Fairbank’s International Arctic Research Center. &#8220;If it further destabilizes, the methane emissions may not be teragrams, it would be significantly larger.&#8221; Since the methane is stored below the sea, the release of the potent greenhouse gas has the capacity of being far larger and quicker than methane released by thawing permafrost on land. In a podcast Shakhova compared the methane built up beneath the East&hellip;This article was originally published on <a href="https://news.mongabay.com/2010/03/massive-methane-leak-in-arctic-could-trigger-abrupt-warming/" data-wpel-link="internal">Mongabay</a>]]>

							<![CDATA[Melting permafrost will be major driver of global warming Melting permafrost will be major driver of global warming mongabay.com September 1, 2008 The thawing of permafrost in northern latitudes will become a major source of greenhouse gas emissions, according to a new study that more than doubles previous estimates of the amount of carbon stored in the frozen soils of Alaska and Siberia. Writing in the September 2008 issue of BioScience, Edward A. G. Schuur of the University of Florida and colleagues show that melting permafrost &#8220;could release as &#8220;could amount to roughly half those resulting from global land-use change during this century,&#8221; according to a statement from the American Institute of Biological Sciences. Reassessing how organic materials are stored during melting and freezing of permafrost, the authors estimate that frozen soils store more than a trillion metric tons of organic compounds. As these soils melt due to rapidly increasing temperatures, orgainc materials decompose, releasing methane and carbon dioxide into the atmosphere and thereby exacerbating warming.

							<![CDATA[Sea ice loss may triple warming over northern Alaska, Canada, and Russia Sea ice loss may triple warming over northern Alaska, Canada, and Russia mongabay.com June 11, 2008 Fast-declining Arctic sea-ice could spur rapid warming in northern Alaska, Canada, and Russia triggering thawing of permafrost and a release greenhouse gases from the frozen soils, reports a new study published in Geophysical Research Letters. &#8220;Our study suggests that, if sea-ice continues to contract rapidly over the next several years, Arctic land warming and permafrost thaw are likely to accelerate,&#8221; said lead author David Lawrence of the National Center for Atmospheric Research (NCAR). The research, funded by the U.S. Department of Energy and the National Science Foundation, looked at whether last summer&#8217;s unusually low sea-ice extent &#8212; more than 30 percent below average &#8212; and warm land temperatures &#8212; more than 2 degrees C above the 1978-2006 average &#8212; were related. Using computer models to simulate the effects of rapid sea-ice loss, the researchers found that Arctic land warms at a rate 3.5 times greater than the average 21st century warming rates predicted in global climate models. The warming, which is most pronounced over ocean areas, can extend up to 900 miles inland. The findings suggest that autumn temperatures &#8212; when sea-ice extent is at its lowest &#8212; could rise as much as 9 degrees F (5 degrees C) along the Arctic coasts of Russia, Alaska, and Canada during extended sea-ice-loss events.

							<![CDATA[Melting permafrost affects greenhouse gas emissions Melting permafrost affects greenhouse gas emissions Climate change and permafrost thaw alter greenhouse gas emissions in northern wetlands Michigan State University August 10, 2007 Permafrost &#8212; the perpetually frozen foundation of the north &#8212; isn&#8217;t so permanent anymore, and scientists are scrambling to understand the pros and cons when terra firma goes soft. Permafrost serves like a platform underneath vast expanses of northern forests and wetlands that are rooted, literally, in melting permafrost in many northern ecosystems. But rising atmospheric temperatures are accelerating rates of permafrost thaw in northern regions, says MSU researcher Merritt Turetsky. In the report, &#8220;The Disappearance of Relict Permafrost in Boreal North America: Effects on Peatland Carbon Storage and Fluxes,&#8221; in this week&#8217;s online edition of Global Change Biology, Turetsky and others explore whether melting permafrost can lead to a viscous feedback of carbon exchange that actually fuels future climate change.

Researchers say global warming is to blame. &#8220;The conventional thinking on treeline dynamics has been that advances are very slow because conditions are so harsh at these high latitudes and altitudes,&#8221; said Dr. Ryan Danby, a biologist at the University of Alberta and lead author of the study. &#8220;But what our data indicates is that there was an upslope surge of trees in response&hellip;This article was originally published on <a href="https://news.mongabay.com/2007/08/melting-permafrost-affects-greenhouse-gas-emissions/" data-wpel-link="internal">Mongabay</a>]]>
