NASA Study Reveals Wildfire Smoke's Impact on Ozone Levels Across the U.S.
A NASA-funded study has identified that wildfire smoke has significantly contributed to increased ground-level ozone pollution across the contiguous United States over the past decade. This pollution, often referred to as smog, has offset nearly four years of ozone-control progress, particularly affecting the West and Midwest regions. The study highlights that wildfires emit gases like carbon monoxide, which, when mixed with other pollutants, form surface ozone. This invisible pollutant poses health risks, including respiratory issues, and can affect plants and crops. The research utilized deep learning to analyze data from 2003 to 2024, revealing that wildfires have reversed ozone reduction trends since 2015. The study also noted an increase in premature deaths linked to wildfire-driven ozone exposure.
