Arctic permafrost -- ground that has been frozen for many thousands of years -- is now thawing because of global climate change, and the results could be disastrous and irreversible.
"The release of greenhouse gases resulting from thawing Arctic permafrost could have catastrophic global consequences," said Dr. Max Holmes, a Senior Scientist at the Woods Hole Research Center (WHRC) who has been advising State Department officials on the problem.
Thawing permafrost releases greenhouse gases (carbon dioxide and methane) into the atmosphere, which accelerates climate change, which in turn causes more thawing of the permafrost.
