Wildfire Smoke Impacts Air Quality in Wisconsin
US · Published Sep 23, 2026
Wildfire smoke from Canada and Minnesota has significantly impacted air quality in Wisconsin, with particulate matter levels rising to dangerous levels.
According to Bart De Stasio, professor emeritus of biology at Lawrence University, particulate matter smaller than 2.5 micrometers can penetrate deep into the lungs, causing respiratory issues.

Impact & Risks

The wildfire smoke poses significant health risks, particularly for vulnerable populations such as older adults, Native Americans, and African Americans. Prolonged exposure to fine particulate matter can lead to respiratory problems and other health complications. A study by Carnegie Mellon University linked wildfire and prescribed burn smoke to 20,000 premature deaths and $200 billion in damages. In addition to health concerns, the smog disrupts daily life, as seen in Green Bay, where public spaces were temporarily closed. The worsening air quality also highlights the broader impacts of climate change, including increased heat stress and extreme weather events.
