Emissions from Melting Permafrost Could Cost Trillions
2015-09-30 17:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: While rain forests have long scored attention for their role in trapping carbon, discussions concerning the Arctic have centered on whether or not, or how much, we are going to allow companies to drill for oil far up north. Now, scientists are suggesting the Arctic should have renewed focus for another reason: Climate change, accelerated by the melting of permafrost and resulting greenhouse gas emissions, could cost the global economy, in the long run, as much as $43 trillion. This analysis...

Climate research: Where is the world's permafrost thawing?
2015-09-13 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: This Saturday at a conference in Quebec, Canada an international research team will present the first online data portal on global permafrost. In the Global Terrestrial Network for Permafrost (http://gtnp.arcticportal.org/) researchers first collect all the existing permafrost temperature and active thickness layer data from Arctic, Antarctic and mountain permafrost regions and then make it freely available for download. This new portal can serve as an early warning system for researchers and decision-makers...

Some permafrost might soak up methane as climate warms
2015-08-21 09:54:00| Climate Ark Climate Change & Global Warming Newsfeed
ArsTechnica: Talk of a warming planet often focuses on places that are cold. Glaciers shrink and raise sea level. Arctic sea ice dwindles, opening an actual northwest passage in the summer. And permafrost thaws, pulling vast amounts of organic matter out of the freezer to spoil and add to the greenhouse gases in the atmosphere. Lots of research has focused on organic-rich permafrost and the amount of carbon dioxide and methane it could produce as microbes break down all that food. But thats only a slice of...

Study shows some permafrost carbon transported by river to the ocean
2015-08-10 15:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Environmental News Network: As temperatures rise, some of the organic carbon stored in Arctic permafrost meets an unexpected fateburial at sea. As many as 2.2 million metric tons of organic carbon per year are swept along by a single river system into Arctic Ocean sediment, according to a new study an international team of researchers published today in Nature. This process locks away carbon dioxide (CO2) - a greenhouse gas - and helps stabilize the earths CO2 levels over time, and it may help scientists better predict how...
