Fixing 'bugs' in climate models: Accounting for melting permafrost
2015-04-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Abrupt climate change within a decade triggered by runaway melting of Arctic permafrost is extremely unlikely, according to a study published in Nature yesterday. Rather, the permafrost, or frozen ground, in the Northern Hemisphere will take decades or centuries to melt and release the carbon stored in the soil. The release will not trigger a catastrophe per se but will exacerbate global warming. "These are large and significant releases, so, over a century, we are going to release 100 billion...

Permafrost Carbon Bomb May Be More of a Slow Burn, Say Scientists
2015-04-09 21:45:00| Climate Ark Climate Change & Global Warming Newsfeed
Guardian: The carbon bomb stored in the thawing Arctic permafrost may be released in a slow leak as global warming takes hold, rather than an eruption, according to new research. Scientists at the US Geological Survey (USGS) found previous predictions of a catastrophic release of carbon dioxide and methane into the atmosphere as permafrost thaws may have been overstated. But the impact on the climate of future permafrost emissions remained significant. More than 1,000bn tonnes of carbon are stored...
Melting Arctic Permafrost To Cause Massive but Gradual CO2 Release
2015-04-09 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: A comprehensive new study of the potential climate change impacts of melting Arctic permafrost says that a vast amount of carbon dioxide will be released from thawing permafrost but that it will seep out gradually, rather than in an abrupt carbon bomb. Working since 2011, a group of 17 Arctic permafrost scientists studied the rate at which permafrost is thawing and the resulting release of CO2. The scientists concluded that Arctic permafrost has undergone a stunning degree of warming, rising from...

Thawing permafrost could be the worst climate threat you havent heard of
2015-04-03 22:28:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Some things get better when you take them out of the freezer. Ice cream, for example, is unarguably more delicious when it gets a little melt-y. (Unarguably, I say! Come at me, trolls.) But other things get remarkably worse. Take bananas - the next time you whip up a smoothie, leave the frozen banana to defrost on your counter and watch in horror as it turns into a yellowish brown pile of watery mucus. And then theres permafrost: You dont even want to know what happens to that shit when it thaws...
Most of Alaska's Permafrost Could Melt This Century
2014-12-19 16:35:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: The permafrost in some of Alaska's most iconic national parks could all but disappear this century, new research suggests. Right now, half of the ground in Denali National Park's is frozen year-round, but if global warming continues at the current pace, just 1 percent of this land could remain permafrost by the year 2100, according to new research presented here at the annual meeting of the American Geophysical Union. Not only could vast swaths of the Alaskan tundra transform into swampy bogs,...
