Wildfire Smoke Affects Millions in US and Canada

Wildfires in northern Minnesota and Canada are causing poor air quality in the Midwest and Northeast. Air quality alerts have been issued in several cities, including New York and Chicago.
Millions of Americans and Canadians are experiencing poor air quality due to wildfire smoke from fires in northern Minnesota and Canada. The smoke has turned the skies orange in some areas and is causing health concerns. Air quality alerts have been issued in New York, Chicago, and Toronto, with officials advising people to stay indoors.
The wildfires are not only affecting air quality but also destroying homes and devastating local tourism. Researchers have found that human-caused climate change is making wildfires more likely and intense, although it is too early to directly link these wildfires to climate change.
A report by Climate Central found that per-person exposure to harmful wildfire smoke in the US was four times higher during 2020-2024 than during 2006-2019. The smoke could continue to be a problem for some time, with hot and dry conditions allowing the fires to keep burning and an elevated risk of new fires.
