"The 2012 wildfire season isn't over yet, but already this year is shaping up to be the one of the worst on record in the American West. According to the National Interagency Fire Center, with nearly two months still to go in the fire season, the total area already burned this year is 30 percent more than in an average year, and fires have consumed more than 8.6 million acres, an area larger than the state of Maryland."
" Yet, what defines a 'typical' wildfire year in the West is changing. In the past 40 years, rising spring and summer temperatures, along with shrinking winter snowpack, have increased the risk of wildfires in most parts of the West.
Studies show that continued climate change is going to make wildfires much more common in the coming decades.
The National Research Council reports that for every degree Celsius (1.8oF) of temperature increase, the size of the area burned in the Western U.S. could quadruple. According to the IPCC 4th Assessment Report, summer temperatures in western North America could increase between 3.6oF and 9oF by the middle of this century."
