I wrote a post a while ago that included a discussion of the risks of rapid methane emission in the Arctic. The general view was probably quite well represented by Michael Tobis’s comment

I think the prevailing opinion remains that it is a very important threat in the long run, but that there is no realistic mechanism proposed for an abrupt release in the space of a few decades or a century.

Since then, however, there appears to be more and more discussion of methane release in the Arctic. There’s a recent post by Jason Box called Is the climate dragon awakening? This post highlights that there is evidence that methane is reaching ocean surface, rather then being converted into the less greenhouse CO2 before getting to the surface.
