Methane, 20x more potent than CO2

This article in the Guardian.co.uk seeks to put in perspective the role of arctic methane in future climate change. The article has many links, so you too can become methane-supersaturated, just like the ocean waters above the East Siberian Arctic Shelf.

If you just wish their conclusion, it is:

"For methane to be a game-changer in the future of Earth's climate, it would have to degas to the atmosphere catastrophically, on a time scale that is faster than the decadal lifetime of methane in the air. So far no one has seen or proposed a mechanism to make that happen."

My opinion? I think methane may be a bigger player than the above quote implies. If you have an opinion, please add it under comments.
