US EditionSmoke From 2023 Canada Fires Linked to Thousands of Deaths: Study
Researchers estimate over 354 million people worldwide were exposed to toxic smoke from Canada's 2023 wildfires, resulting in an estimated 82,000 premature deaths globally.
- Smoke from Canada's wildfires in 2023 caused an estimated 82,100 premature deaths worldwide, according to a study published in the journal Nature.
- The period from June 26 to July 7, 2023, accounted for about 5,400 acute deaths in the United States and Canada.
- Extreme fire conditions in Canada, fueled by climate change, burned about 18 million hectares, significantly impacting air quality across North America and western Europe.
- Qiang Zhang, the study's lead researcher, expressed surprise at the findings, calling the results 'striking' and highlighting the smoke's tremendous health burden.

Study estimates 2023 Canadian wildfire smoke caused 82,000 premature deaths globally
VANCOUVER — Smoke from record-breaking Canadian wildfires in 2023 caused an estimated 5,400 acute deaths and about 82,100 premature deaths worldwide, a new study shows. The study published in the peer-reviewed journal Nature acknowledges some variation in mortality estimates depending on the methods used, but says its overall conclusion is the smoke led to an […]
Long-range PM2.5 pollution and health impacts from the 2023 Canadian wildfires
Smoke from extreme wildfires in Canada adversely affected air quality in many regions in 20231,2. Here we use satellite observations, machine learning and a chemical transport model to quantify global and regional PM2.5 (particulate matter less than 2.5 μm in diameter) exposure and human health impacts related to the 2023 Canadian wildfires. We find that the fires increased annual PM2.5 exposure worldwide by 0.17 μg m–3 (95% confidence interval,
A peer-reviewed study indicates that smoke from record forest fires in Canada in 2023 caused approximately 5,400 short-term deaths and about 82,100 long-term deaths worldwide
