Bubble, Bubble. GigaTons of Methane Trouble // Published on Jun 28, 2017
Vast amounts of methane exists within ocean floor sediments on the Eastern Siberian Arctic Shelf, in the form of methane hydrates & free methane gas.
Up to recently, gas release to the shallow water column (50 meters deep) and atmosphere has been slow, with the subsea permafrost acting as a million corks on a million champagne bottles to contain the methane.
Now, rapid thawing of the permafrost has released 10% of the corks, allowing rapid ongoing increases in methane release.
