Wildfires in Colorado burned down more than 600 homes and cost insurers $450 million, making 2012 the costliest season for blazes in the state's history. New Mexico suffered its worst-ever fires in May and June.
"This is a scary trend," Bloomberg View editors wrote on July 16. "In the 1960s, Colorado had about 460 fires a year that burned an average of 8,000 acres, according to a report compiled from state forest service records. In the past 10 years, the state averaged about 2,500 fires a year that consumed about 100,000 acres."
