The Hidden Danger in Wildfire Smoke

What if the most dangerous part of wildfire smoke isn't the smoke itself? A new NASA-funded study has revealed that wildfires create a hidden air pollution threat: ground-level ozone. Unlike smoke particles that are visible in the air, ozone forms when gases released by wildfires react with sunlight. This invisible pollutant can travel hundreds or even thousands of kilometers from the fire, affecting air quality and human health far from the flames. Using satellite observations, weather data, and air quality measurements, scientists found that wildfire-generated ozone has become a major contributor to pollution and may be responsible for thousands of excess deaths each year. The findings also show that increasing wildfire activity is reversing decades of progress in reducing ozone pollution. Watch to discover how NASA satellites are helping scientists uncover this hidden consequence of a warming world. 🌎 Subscribe to @BeyondEarthBuckleUp for more NASA Earth science, climate, and space discoveries.
