Permafrost, a vicious cycle

carbonbrief : "Scientists are concerned that permafrost thaw and the subsequent release of carbon will fuel a positive feedback loop, which will accelerate climate change. Warmer conditions cause the release of carbon dioxide and methane from permafrost, which means more warming, which in turn causes more permafrost to thaw and so on.

Calling this cycle a 'positive' feedback might be misleading. It's more of a vicious cycle."
