This summer, North America is facing a prolonged period of poor air quality due to intense wildfires raging across Canada. Smoke from these wildfires has significantly impacted cities like Chicago and Detroit, ranking their air quality among the worst in the world. Reports indicate that many areas, including parts of Michigan and New Hampshire, are experiencing unhealthy air conditions, prompting alerts across five U.S. states. The smoke has even reached the Bay Area and is forecasted to affect numerous regions, including the Midwest and Great Lakes areas. Local authorities are advising residents to stay indoors as the situation leads to hazy skies and concerns over respiratory health. As wildfires continue to burn, the effects of both smoke and dust from as far away as Africa complicate the air quality crisis.
