Unprecedented 2007 Arctic Fire Released a Year's Worth of Stored Carbon

in 2007, the largest fire ever recorded in the Arctic swept across the Alaskan Northern Slope region, releasing an estimated 2.1 teragrams (2.3 million tons) of carbon into the atmosphere. Researchers estimate that the release of carbon was equivalent to a year’s worth of carbon storage for the entire Arctic tundra biome. Climate warming in the Arctic may lead to a greater frequency of such large fires, putting permafrost at risk of thawing and releasing more CO2.

Researchers Overpeck and Udall cite a litany of troubling trends to support their prediction: “soaring temperatures, declining late-season snow pack, northward-shifted winter storm tracks, increasing precipitation intensity (note: not total rainfall), the worst drought since measurements began, steep declines in Colorado River reservoir storage, widespread vegetation mortality, and sharp increases in the frequency of large wildfires.”
