Arctic methane leaks could be accelerating global warming

Apr 23, 2012 | Posted by: roboblogger | Full story: AndhraNews

The high concentrations of the greenhouse gas recorded in the air above cracks in the ice could be evidence of yet another positive feedback on the warming climate - leading to even faster Arctic warming, the New Scientist reported.

Tho arctic permafrost & shallow ocean methane release to the atmosphere is increasing, not a major rise in global methane levels are seen. Work to decrease rice paddy emissions, animal emissions & decrease escaping methane from oil industry operations may be helping, altho the recently ended but deep & extended solar minimum could also have had some influence in slowing the rise of atmospheric methane.

There are controls of atmospheric methane, as mentioned. However, if great permafrost & clathrate methane emissions helped push world methane levels to 4-5000 ppb, human ability to control greenhouse warming would be compromised.

The question remains, where is the methane originating?
