A study published in Science challenges the common perception about wildfires: burning areas of vegetation with controlled, low-intensity fire not only does not worsen air quality in the long term, but significantly improves it.

Wildfires have worsened ozone levels across the United States so much over the last decade that they have reversed around four years of progress, a new study has found. insideclimatenews.org/news/0906202...

Wildfire smoke is stoking a new challenge for cleaner air. A NASA-supported study published Thursday found that, over the last decade, wildfires have worsened ground-level ozone pollution across much of the contiguous United States, creating unhealthy air far from active flames. bit.ly/4ocpsSt

Wildfire smoke has reversed US progress toward ozone air quality, study finds -- Since 2015, destructive fires have undone years of effort to reduce ozone levels, underscoring a growing public health crisis www.theguardian.com/us-news/2026...

Worsening wildfires have been sending so much smoke across the country in recent years that they've actually reversed the country's progress in cutting pollution from ozone (the main ingredient in smog). A new study shows what happened:

Larger US wildfires are reversing a decade of progress on air quality, a new study finds. Smoke-driven ground-level ozone has increased by 4% since 2015, offsetting strict federal regulations on power plants and vehicles. This is also linked to 318 additional deaths annually.

New study finds increased wildfire smoke has erased 4 years of progress in controlling surface ozone pollution. "Premature deaths from fire-sourced ozone have increased by 318 deaths per year since 2013, with post-2013 mortality 46% higher than pre-2013 mortality." www.science.org/doi/10.1126/...
