Permafrost Carbon Sink Decreasing

I first began to become aware of the phenomenon of melting permafrost in the early 1980s when I read about tombstones of Alaska's early settlers tipping over because permafrost was melting. And now, a long time Alaskan resident that I met recently shared how winter's lowest winter temperatures in the Arctic are about 20 degrees above normal. Then I read about how it is the higher winter temperatures that are having the greatest influence in permafrost melting.
