Permafrost thaw threatens Arctic infrastructure
2014-12-19 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Deutsche-Welle: Global warming is changing the Arctic - while some herald the opportunities that come with easier access, the thaw could literally yank the ground out from under communities. DW talked to an expert about the risks. DW: Why should we be concerned about warming and thawing in the Arctic? Hugues Lantuit: Permafrost is frozen ground in the Arctic, and it's currently warming at a fast pace. What we've done in a European Union project is to build for the first time an integrated database on permafrost...

Permafrost soil: Possible source of abrupt rise in greenhouse gases at end of last Ice Age
2014-11-20 13:00:00| LifeSciencesWorld
[NEWS] medien@awi.de 49-471-483-12007 Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research Bremerhaven/Germany, 20 November 2014. Scientists from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) have identified a possible source of carbon dioxide (CO2) and other greenhouse gases tha…
The Good and Bad Climate News from Permafrost Melt
2014-09-12 16:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Climate Central: Earth's subterranean carbon blisters are starting to pop. Carbon inside now-melting permafrost is oozing out, leaving scientists scrambling to figure out just how much of it is ending up in the atmosphere. Whether recent findings from research that attempted to help answer this question are good or bad climate news might depend on whether you see an Arctic river basin as half full of mud -- or half empty. Frozen soils known as permafrosts can be found across the planet, and they're concentrated...
Melting permafrost could worsen water quality in Rockies

Colorado Independent: Heavy metals concentrations are increasing in the Snake River, near Keystone, Colorado, and some scientists think global warming may be a factor. We may not yet know exactly how global warming will affect all the complex parts of Rocky Mountain ecosystems, but its not for lack of trying. Scientists are prodding the soil, counting wildflowers, measuring winds and gauging snowfall nearly every day to unravel the mysteries of the anthropocene, this present-day geological epoch in which humans are...

Sunlight boosts CO2 from thawing permafrost
2014-09-05 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
ClimateWire: Arctic permafrost holds about twice as much carbon as the atmosphere, making its ultimate fate a key factor in the severity and pace of climate change impacts. Now a study reports that old assumptions of how permafrost carbon breaks down in Arctic lakes and rivers may be wrong. Instead of bacteria being responsible for the conversion of carbon into carbon dioxide, the real culprit in many cases is sunlight, according to the research supported by the National Science Foundation. The findings...
