Climate: Interior West forests on verge of becoming net carbon emitter -- 11/11/2010 -- www.eenews.net - 0 views

Peter Vidito on 16 Nov 10"Forests in the Interior West could soon flip from carbon sink to carbon source, forest experts say. The region's forests once absorbed and stored more carbon from the atmosphere than they released. But huge conflagrations -- like the 138,000-acre Hayman Fire in Colorado in 2002 and the Yellowstone fires of 1988, which scorched 1.2 million acres -- combined with a series of severe bark beetle infestations and disease outbreaks, have left large swaths of dead, decomposing trees in almost every major Western forest. Those dead trees are releasing massive amounts of carbon dioxide, turning the region into a net emitter of carbon rather than a CO2 sponge."
