Thanks Loafer! Lets hope for a clearer picture when we have this years data?

sat measurements of methane the past 10 Novembers.?

G-W - Is there an image missing from your post - all I can see is a blank space and the words "sat measurements of methane the past 10 Novembers.?"

I was going to make a joke about it making more sense than most of your posts, but I wouldn't want you to think I was being serious!

There is a Youtube video of the methane levels from November 2002 through to 2011. Quite alarming if it's accurate...

Ah! YouTube is blocked at my office. Thanks.

I took the methan images from here:

this gives the full ten years for each month. If you wonder why Dec,Jan, Feb show such alarming rises compared to summer it is well explained in the 'comments' section.

As for 'methane releases' it seems 2011 broke 2010's temp record across the Arctic region. Then I wonder why I worry about such????

With the promise of an El-Nino on the horizon what would global (and more importantly Arctic) temps do then with Solar on the upswing and the PDO-ve running out of steam???

Thanks to Weathership for bringing this to our attention;

A bump for the thread now melt season is upon us!

I'll put it in the correct thread GW although there is no need as you have already done so.

Enter stage left GW. Sorry don't have access to the full paper.
Arctic methane leaks threaten climate

As Arctic sea ice breaks apart, massive amounts of methane could be released into the atmosphere from the cold waters beneath.
High concentrations of the greenhouse gas have been recorded in the air above cracks in the ice. This could be evidence of yet another positive feedback on the warming climate – leading to even faster Arctic warming.
The Arctic is home to vast stores of methane – there are billions of tonnes of methane in permafrost alone. It is a potent greenhouse gas, so a major methane release would greatly accelerate climate change. The gas is found in icy crystals called hydrates beneath the shallow seas that flood some areas of the continental crust, as well as in permafrost. It is also being released from Arctic wetlands.
But this doesn't explain why Eric Kort of the Jet Propulsion Laboratory in Pasadena, California, and his colleagues found patches of methane in remote regions of the Arctic Ocean, far from any of these known methane sources.
The team found the patches during five flights over the Arctic Ocean between 2009 and 2010, as part of a project to systematically map greenhouse gas levels in the atmosphere.
