From a friend. CH4 is 25 times the greenhouse gas as CO2. <<Somebody posted this today. Maybe your son-in-law would like the links.... The best thing I've found are these monthly satellite maps of Arctic methane, but they measure levels pretty high in the troposphere ftp://asl.umbc.edu/pub/yurganov/methane/MAPS/NH/ Compare especially Novembers over the last few years. The methane certainly seems more concentrated this most recent November, but not the vast areas of 2ppm + concentrations one might expect from a really big blowout. [Edit: Ah, I see the December image is now up--and it shows quite strong concentrations over the ESAS as well as the southern-most reaches of the tundra, aka permamelt: ftp://asl.umbc.edu/pub/yurganov/methane/MAPS/NH/ARCTpolar2011.12._AIRS_C... Compare that image with any other December image and you will find it strikingly darker red over these areas this year than any other--something is definitely afoot with Arctic methane this year!]
