A new study found that long-term exposure to fine particulate pollution (PM2.5) from wildfire smoke is linked to about 24,100 deaths per year in the United States, showing a major health impact beyond direct fire fatalities. The tiny particles in wildfire smoke can penetrate deep into the lungs and bloodstream, worsening respiratory and cardiovascular diseases and increasing mortality. Researchers say that climate change, forest mismanagement and expanded development in fire-prone areas are contributing to more frequent and severe wildfires that worsen air quality. The findings highlight the growing danger that wildfire smoke poses as a public health issue linked to global warming.
