On the Rise: Siberian lakes—Major sources of methane

By Sid Perkins, 15:55 PM April 15, 2008

Recent warming in Siberia is liberating carbon that had been locked in the permafrost for millennia. Consequently, Siberian lakes are making a surprisingly large contribution to atmospheric methane, a planet-warming greenhouse gas, according to a new analysis of the methane bubbling from those lakes.

Previous studies had suggested that most northern Siberian lakes sit atop permafrost containing rich soil. Methane-making microbes in the oxygen-poor lake-bottom sediments render the lakes major ...
