Anthropogenic warming drives earlier wildfire season onset in California
Overview
Paper Summary
Wildfires in California are starting earlier, driven by climate change and natural climate variability. While natural variability played a significant role, anthropogenic warming advanced fire season onset in most ecoregions, especially in the north, primarily due to warmer temperatures and earlier snowmelt. Southern California shows less of this trend due to fuel limitations and more complex climate influences.
Explain Like I'm Five
Warmer temperatures and earlier snowmelt are causing wildfires in California to start sooner each year, especially in the northern part of the state.
