New research indicates that intensifying wildfires have reversed national air quality progress by causing a 4% rise in ground-level ozone since 2015.Scientists estimate that this pollution surge is responsible for 318 additional premature deaths each year due to severe respiratory damage.Data from the EPA and new artificial intelligence models reveal that wildfire smoke now accounts for rising ozone levels across the Northern Rockies and Midwest.Experts warn that existing safety standards are insufficient and urge immediate policy updates to address the health risks posed by climate-driven fires.
