A new study published in Nature Communications Earth & Environment reveals that climate change contributes to thousands of annual deaths and significant economic costs due to wildfire smoke in the US. From 2006 to 2020, climate change was linked to approximately 15,000 deaths and $160 billion in costs. The study highlights the health impacts of PM2.5 from wildfire smoke, particularly affecting vulnerable populations. Experts emphasize the need for awareness and action to mitigate the effects of climate change on wildfires.
