U.S. wildfires are up to four times larger and three times more frequent than they were in the 1980s and '90s , authors say.

Fast-moving fires have been particularly destructive, accounting for 78% of structures destroyed and 61% of suppression costs.

Climate change sets stage for larger and more intense fires, but humans are actively fanning the flames, they say.

Soil moisture in the Los Angeles region was about 2% of historical levels for that time of year when the fires began on Jan. 7, 2025 . As the factors that can drive wildfires converge, the potential for increasingly severe wildfires looms ever larger. Severe fires also release large amounts of carbon from trees, vegetation and soils into the atmosphere, increasing greenhouse gas emissions and exacerbating climate change, contributing to more extreme fire seasons.
