I've been trying to read up a bit on the methane clathrate "bomb" or "gun" theory lately, it seems to be popular among some fringe "we're all gonna die anyway" communities. Though my impression was that the vast majority of climate scientists don't consider it to be a very plausible threat [1]. It is based on some real scientific publications, but as far as I can tell in the realm of "very implausible theory".
There is definitely a concern about multiple feedback loops involving methane from clathrates, permafrost and also wetlands. There's also considerable uncertainty about the origin of methane emissions. But as far as I can tell the methane "bomb" theory shouldn't be our major concern.
