Not much to say except…
In simulations of future warming we find that the permafrost carbon feedback increases global mean temperature by 10–40% relative to simulations without this feedback, with the magnitude of the increase dependent on the evolution of anthropogenic carbon emissions.
From Anthony et al. Methane emissions proportional to permafrost carbon thawed in Arctic lakes since the 1950s. And these feedbacks aren’t in the IPCC climate models. Conformation: A last message from the Department of Energy and Climate Change.
I expect it will.
