What Is the Link Between Wildfires and Climate Change (and How Does It Affect Air Quality)?
Climate change is intensifying wildfire behavior through longer fire seasons, hotter temperatures, prolonged droughts, and drier vegetation that ignites more easily and burns more severely. What once defined California’s fire risk from mid-April through October has expanded into a year-round threat, fundamentally altering how communities prepare for and respond to wildfire smoke exposure.
The numbers tell a striking story. California has seen a fivefold increase in annual burned area since 1972, according to NASA research. In 2026 alone, CAL FIRE has already documented 3,838 wildfires across 195,439 acres, with incidents like …
