ljgeoffThis is the thing: The sun will come in this summer and the comming summers and hit the black and white arctic ocean, and what little energy that is bounced off the remaining snow and ice will be held in by the methane that's building up there like an eiderdown comforter. Which will accelerate more methane release. This will happen. It is physics. It will happen in my lifetime (unless I get hit by a truck on the way home) so I won't have to wonder.
It'll be interesting to see what happens to the jet stream.
From Arctic News:
Dr. Leonid Yurganov, Senior Research Scientist, JCET, UMBC, and member of AMEG, produced the above images with IASI/METOP satellite data (EUMETSAT).
The images show methane levels for 2008, 1-10 November, and for 2011, 1-10 November.
The images show a striking increase of methane over the shelf areas of the Arctic Ocean.
For reference, the image on the right is added, showing predicted methane hydrates, as published by WWF(1) with surface temperature hotspots added.
Dr. Yurganov points at the threat of large emissions of methane from clathrates (methane hydrates) in the Arctic, and urges others to support his proposals for further satellite methane monitoring.
Current growth of methane is being monitored by the Atmospheric Infrared Sounder (AIRS) facility on NASA's Aqua satellite.
Dr. Yurganov has been using AIRS data for years and points at an image he produced using AIRS data. The image shows that, during the autumn of 2011, the anomaly in the Northern Hemisphere was substantially larger than the anomaly in the Southern Hemisphere.

Monthly mean maps of methane are available at Dr. Yurganov's website. The maps have been produced using AIRS data since 2002 up to now, for both the Northern Hemisphere and the Southern Hemisphere. The maps are at:

Comparisons with other instruments for the Arctic are still few or lacking. Examples are for TANSO, May-November, 2010:
