KapteinB:

    One possibility is conspicuously missing from the list. Scientists have long feared that thawing Arctic sediments and soils could release huge amounts of methane, but so far there’s no evidence of that

I'm surprised this got only a passing mention in the article. For years now I've been reading about the mysterious craters in Siberia that may or may not be caused by methane gas escaping as the permafrost thaws.
