Smoke from wildfires in Canada and the western United States is blanketing North America. As of July 21, 2021, air quality alerts had been issued even in the U.S. East, and, by mid-week, even New York City was blanketed with haze from wildfire smoke. The New York Timesreported on July 21:
In recent weeks, a series of near-relentless heat waves and deepening drought linked to climate change have helped to fuel exploding wildfires. In southern Oregon, the Bootleg Fire grew so large and hot that it created its own weather, triggering lightning and releasing enormous amounts of smoke. But more than 80 large fires are currently burning across 13 American states, and many more are active across Canada.
