Smoke From Canada’s Wildfires Turns Skies Sickly Orange across the Eastern U.S.

Smoke from devastating wildfires in Canada is blanketing a large swath of the Midwest and Northeast this week, causing cities across the region to issue air quality warnings.

The extreme levels of smoke mean even able-bodied adults would be wise to take some precautions to protect their health. The increasing severity of wildfires across the continent—driven in part by climate change—means even places where blazes are not burning will still suffer the impact.

More than 100 fires are burning out of control across Canada as of Wednesday, with hundreds more being monitored or battled. The smoke has drifted south and east, turning skies hazy from Minnesota to New York. Particularly dramatic images have emerged from Toronto, where commuters went to work on Wednesday morning under orange skies. The region is also dealing with a heat wave, with temperatures well above 90 degrees Fahrenheit in many areas and an even higher heat index.
