Kyoto down to ashes

From Nature (paid subscription required):

"In the summer of 2003, wildfires raced across the region [Siberia, during a heatwave], incinerating an area of some 22 million hectares: slightly smaller than the state of Oregon. As the trees went up in smoke, they released about 250 million tonnes of carbon into the atmosphere — roughly the same amount as industrialized countries have pledged to cut from their emissions by 2012 under the Kyoto agreement."
