Air-quality alerts have been posted in New York City, with 740 fires raging across Canada from the Arctic Circle to southern Ontario.

The worst air quality in recent years occurred in June 2023, when the smoke became so thick it created an orange haze over the city. However, the subpar air quality has returned to the city in each of the past two summers as well, including multiple times earlier this year.
