More than 100 wildfires are burning in Canada, where a train crew in northern Ontario filmed themselves surrounded by flames before being safely evacuated. Winds are carrying the smoke southeast.
Warnings about unhealthy air conditions Wednesday extended from Minnesota through Toronto and into New York. Unusually hot summer temperatures were expected, too.
The best advice is to stay indoors to avoid both the smoke and the extreme heat, said Tyler Hasenstein, meteorologist with the National Weather Service in Chanhassen, Minnesota.
“Those two things coinciding with each other is not good from a health perspective,” he said.
Dan Westervelt, associate professor at Columbia University’s Climate School, said severe drought conditions combined with heat in Canada and the U.S. have created “a perfect storm for really dry conditions to provide a lot of fuel for these wildfires to burn.” Research shows warming temperatures from burning coal, oil and gas are making fires more frequent and intense.
High levels of fine particulate matter in the air from wildfire smoke may be unhealthy for sensitive groups, such as children and people with heart or lung conditions. The particulates can cause shortness of breath, coughing, dizziness or fatigue and aggravate heart and lung diseases and other chronic health issues.
Experts suggest wearing a N95 mask if you have to be outside and keeping your indoor air cleaner by closing windows and running an air purifier or air conditioner.
