Ticking Arctic Carbon Bomb May Be Bigger Than Expected

sciencehabit writes "Scientists are expressing fresh concerns about the carbon locked in the Arctic's vast expanse of frozen soil. New field studies quantify the amount of soil carbon at 1.9 trillion metric tons, suggesting that previous estimates underestimated the climate risk if this carbon is liberated. Meanwhile, a new analysis of laboratory experiments that simulate carbon release by thawed soil is bolstering worries that continued carbon emissions could unleash a massive Arctic carbon wallop."

I'm recovering with a flu so I might have missed something when reading TFA, but this CO2 release seems to be in addition to the expected massive release of methane from frozen Siberian permafrost.

If so, we're fucked^2 I see no way we can avoid the positive feedback loops of AGW. Sandy will be a pleasant memory from the past, to the citizens of NYC.
