Carbon loss from an unprecedented Arctic tundra wildfire : Nature : Nature Publishing Group

Carbon loss from an unprecedented Arctic tundra wildfire : Nature : Nature Publishing Group.

More grim news – “In 2007, an area of more than 1,000 square kilometres of Alaskan tundra was destroyed by a single fire, more than doubling the cumulative area burnt in this region since 1950. Michelle Mack and colleagues now show that, in the process, 2.1 teragrams of carbon was released and about one-third of soil organic matter burned away, thereby potentially exposing permafrost soils to thaw. The amount of carbon released from the entire burn was comparable to the annual net carbon sink of the entire Arctic tundra biome during the past 25 years of the twentieth century.”
