The Growing Fire Season
Over the past 40 years, the US wildfire season has grown by an average of 78 days. Fires are burning 2-3 times more acreage annually compared to the 1980s and 1990s. The 10 largest fires in California history have all occurred since 2017.
Why Climate Change Matters
Higher temperatures dry out vegetation, creating more fuel for fires. Reduced snowpack means less moisture in summer. Drought conditions persist longer and cover larger areas. Earlier snowmelt extends the fire season. Bark beetle infestations (worsened by warmer winters) create millions of dead trees.
Future Projections
Scientists project that fire season length will increase by 3-4 weeks by 2050. The area burned annually could double or triple by end of century. Previously low-risk areas in the Southeast, Northeast, and Pacific Northwest are seeing increasing fire activity.
