A new study finds that megafires in the Western U.S. are causing premature deaths and have undermined improvements in air quality from reduced vehicle emissions. The study, published in The Lancet Planetary Health, found that air quality worsened in the West from 2000 to 2020, with concentrations of black carbon rising 55 percent. The authors estimate that fires have caused an additional 670 premature deaths each year.
"All the efforts for the past 20 years by the EPA to make our air cleaner basically have been lost in fire-prone areas and downwind regions," said University of Iowa professor Jun Wang, the study's lead author. "We are losing ground."
Axios notes that there is an emerging global consensus that adopting Indigenous fire management practices, including controlled burning, can help mitigate fire risks, and that smoke from managed burns is less intense and may be less toxic.
