Human exposure to wildfires in the U.S. more than doubled in the past two decades. A climate scientist looks at who is at risk and why
The following essay is reprinted with permission from The Conversation, an online publication covering the latest research.
Most fires in the U.S. are suppressed before they have a chance to threaten communities, but the winds were too strong to send helicopters into the sky to help contain Maui’s fires on the first day, leaving firefighters to battle the blazes from the ground. Instead, three-quarters of this trend was driven by intense fires growing out of control and encroaching on existing communities.
Recent research on California’s fires found that almost all of the increase in that state’s burned area in recent decades was due to anthropogenic climate change – meaning climate change caused by human activities. If you picture wildfire photos taken from a plane, fires generally burn in patches rather than as a wall of flame. Pockets of homes within the fire boundary survive, but many also burn.
