The Arctic heatwave: here’s what we know | Climate change | The Guardian
The real fear around the Arctic for the longer term, I find when talking to people, comes from the idea of “runaway” warming from methane release. Warming could release stores of methane – a strong greenhouse gas – from permafrost or frozen sediments at the bottom of the ocean, which would add to the warming from our own activities. There is more than twice the amount of carbon in the permafrost as in the atmosphere, and thawing has already begun.
