The methane hydrate feedback revisited

Excellent article, thank you for posting it, the size of the potential methane sources is staggering (a consequence that the clathrates, in particular, have had a long time to build up since their last major release). Joe, it blows my mind, that at this point, nobody has a climate model that incorporates the methane feedbacks from the melting permafrost. With an ice free summer arctic coming in the next 10 years we’re going to be living large releases before we get them in our models. We’ve known about these potential runaway feedback triggers for more than a decade (Amazon rainforest dry-out, melting permafrost, melting clathrates to name a few), its a shame we’re not further down the road on forecasting their potential effects yet. It feels like we’re really running out of time (i.e. just having enough time to forecast the runaway feedback effects before they actually st...
