Hundreds of wildfires have been blazing across Canada and Mexico since last week, and new satellite images released by NASA show the smoke pouring out of some.
Firefighters have been battling this army of wildfires, which are scattered across various Canadian provinces, including over 30 blazes in Alberta and British Columbia and 10 in Ontario, according to the Canadian Interagency Forest Fire Centre. Smoke from multiple fires flowed into the United States and blanketed Wisconsin last Sunday (May 12), prompting the state's first air quality advisory of the year.
