- Arctic methane release
The release of methane from the Arctic seabed is a potential contribution to
global warminginduced by Arctic shrinkageand the thawing of seabed permafrost. Recent observations [ [http://www.independent.co.uk/environment/climate-change/exclusive-the-methane-time-bomb-938932.html The Methane Time Bomb] ] of accelerated release in arctic ocean regions of Siberiamay indicate the start of a "runaway" situation due to a positive feedbackloop, with the increased atmospheric methane causing additional warming, in turn causing accelerated releases.
