The 2026 wildfire season has already consumed twice the acreage that burns in an average year at this point in the calendar. According to the National Interagency Fire Center, 2.4 million acres had burned across the United States by mid-June 2026, compared to a ten-year average of approximately 1.2 million acres through the same date.
The most visible consequence is smoke. Wildfire smoke has drifted over more than 30 states this season, carrying fine particulate matter — PM2.5, particles smaller than 2.5 micrometers — deep into the lungs and bloodstream of millions of people who may never see a fire.
