Methane in the Arctic Ocean

At http://phys.org/print304596241.html … (the same story is at http://wattsupwiththat.com and has hundreds of comments to wade through) but basically we learn that methane is bubbling up from the East Siberian continental shelf system in the Arctic Ocean (opposte Ellesmere Island and the top of Greenland). This shelf system was dry land in the Pleistocene, according to some geologists, part of the Beringia complex (now drowned). It is thought to harbour the remains of lots of Pleistocene mammals. The alarmist slant to the paper is that this methane is a major environmental and CAGW problem – capable of leaking into the atmosphere. However, it is being produced in cold sea water – which is extremely cold in the Arctic winters. This is reminiscent of what Tim Cullen was saying at his various methane posts at http://malagabay.wordpress.com
