We can see that there are large buildups of methane clathrates in permafrost regions.
Climate scientist James Hansen has predicted that the release of the permafrost methane clathrates could cause runaway climate change.
We know that some have related the Triassic Extinction event to the release of Permafrost Clathrates.
Do we know how much methane is stored in the permafrost? Do we know at what temperature it will be released? Can we model the release of methane into the atmosphere in the same way we can model the release of carbon dioxide?
My question is: Is there evidence to suggest that the release of methane clathrates in permafrost regions will impact climate change?
