It's been a devastating year of forest fires around the world, with blazes wreaking havoc from Portugal to Canada to Australia. The picture hasn't been pretty in the U.S., either. From Jan. 1 through Aug. 20 of this year, 648,768 acres of U.S. national forest land have gone up in flames. The U.S. Forest Service estimates that it will need to spend $773 million on firefighting this year, but Congress has approved only $418 million. The Wilderness Society has rounded up these and plenty more facts about wildfires -- only on the Grist Magazine website.
