Update on the permafrost emissions feedback potential. This is a quite thorough review of an even more thorough recently published review of the immense amount of research that has been concentrated on this subject. There are many interesting conclusions, the most basic of which is that the problem is serious and the IPCC has been wrong to exclude it when making projections. “The overall conclusion is that, although the permafrost feedback is unlikely to cause abrupt climate change in the near future, the feedback is going to make climate change worse over the second half of this century and beyond.” They show about how much worse under several possible scenarios.
