The Burning Season
Earlier in the year, research published in the online version of the journal Science concluded that the uptick in both strength and number of wildfires is consistent with a changing climate. Dr. Anthony Westerling led the research while at the Scripps Institution of Oceanography. He was interviewed on NPR's Science Friday back in July. You can hear the segment here.
The terrible irony of the increase in forest fires is that the problem could be self-reinforcing; that is, as the fires burn they loose more carbon into the atmosphere, exacerbating the condition that led to the increasing fires in the first place.
