wildfires_people_85861.jpg

FILE - In this May 6, 2009 file photo, a home is threatened by a wall of flames near Santa Barbara, Calif. People are causing five out of every six wildfires in the United States and tripling the length of America’s wildfire season, a study of 20 years of fires finds. Even as climate change worsens the nation’s wildfire season, making it longer and easier to burn more acres, a new study says the human ignition factor plays an even bigger role on top of that. While fire experts have long blamed people more than lightning, this study digs into the details of how and where the people problem is and how it interacts with global warming to make matters worse.
