The Embassy of the U.S.A., Ottawa - Current Issues: "Warming Arctic Might Accelerate Climate Change, Scientists Say
Results affect Arctic tundra, possibly other global ecosystems

NASA-funded researchers have found that, despite subzero temperatures, a warming Arctic may add more carbon to the atmosphere from soil, further accelerating climate warming, according to an October 12 NASA press release.

'The 3-to-7-degree Fahrenheit rise in temperature predicted by global climate computer models could cause the breakdown of the arctic tundra's vast store of soil carbon,' said Michelle Mack, an ecologist at the University of Florida (UF) and a lead researcher on a study published in last week's issue of the journal Nature."
