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.

lost his senses. When he looks down, paraphrase the question back at him.
