Effects of climate change on wildfires and future air quality.
In a Nutshell:
Harvard atmospheric chemists Dominick Spracklen, Loretta Mickley, and Jennifer Logan investigated the impact of climate change on wildfire activity and air quality in the western United States for the 2000 to 2050 time period. They found that rising temperatures in the Pacific Northwest and Rocky Mountains could increase the area burned by wildfires in these regions by as much as 75-175% by mid-century. Spracklen and co-workers also calculated that one important type of smoke particle -- organic carbon aerosols -- could increase by about 40 percent averaged over the West, with implications for human health and visibility.
