Sub-sea methane instability

As reported today in various media, including Climate Progress, an NSF article and the Wall Street Journal, there is a paper in the current edition of Science that points to an urgent need for further research into methane venting from sub-sea deposits in the arctic.

If the measured CH4 escaping from the shallow seas is a new phenomenon, then it has serious implications for the climate. Current climate models do not provide for this, and in the near term, it would mean a sudden warming of the earth if the vast amounts of trapped methane were to escape to the atmosphere.
