Thawing of Arctic Ocean releases lots and lots of methane

Not that this is in some scientific journal, rather this article appeared on Digital Journal: Scientists worry about giant plumes of methane in Arctic Ocean

It tells of how the current warming climate is causing the seabed of the Arctic Ocean to thaw, thereby releasing all the trapped methane. In the shallow waters of the East Siberian Arctic Shelf, the methane is released into the atmosphere without oxidising into carbon dioxide.

Not all scientists agree that these methane plumes do exist, much less, are of any cause for worry. But this is still quite an interesting article to read. After all, ice traps air as well. If the glaciers melt, will not carbon dioxide and methane that was trapped in and under these ice also be released into the atmosphere?
