By the end of this century, permafrost in the rapidly warming Arctic will likely emit as much carbon dioxide and methane into the atmosphere as a large industrial nation, and potentially more than the U.S. has emitted since the start of the industrial revolution. More information on the findings of an international team inculding scientists from the Alfred Wegener Institute can be found in this press release by the Northern Arizona University...
