Wildfires have become part of California life. Of the 17 largest wildfires in California history, 16 have occurred since 2003, and nine of the 17 have occurred in 2020 and the first nine months of 2021. Wildfires now are more frequent, larger, and hotter. They feature firenados, heat domes with dry lightning, and wildfires have crossed over the granite wall of the Sierra Nevada to burn the eastern side. Vegetation in California is adapted to wildfire, it will burn. Our preparation to reduce wildfires relies on forest thinning and prescribed burns, but they don’t always do the job: The Camp Fire that burned Paradise and killed 85 people moved quickly across a thinned-out forest. Our focus needs to be to home hardening, that is making homes resistant to flames, as well as discouraging further human encroachment into wilderness areas.
