Wildfire activity across western U.S. forests has seen substantial variability over the past century with changes in human settlement, fire management policies and climate variability. Since the mid-1980s, the amount of fire across western U.S. forests has increased eight-fold leading to widespread forest mortality, carbon emissions, periods of degraded air quality, and substantial fire suppression expenditures.
Although numerous factors aided the recent rise in fire activity, observed warming and drying have significantly increased fire-season fuel aridity, fostering a more favorable fire environment across forested systems. Human-caused climate change was responsible for half of the documented increases in fuel aridity since the 1970s and contributed to a substantial increase in forest fire extent over the past three decades.
