As global warming causes soil temperatures to increase, some of the billions of tons of carbon frozen in Arctic permafrost will will be released into the atmosphere, and accelerate climate change. This is a big unknown. Now there’s a simple model of permafrost carbon based on direct observations of carbon in Arctic permafrost.
