Wildfire smoke blankets North American skies

This map shows the concentration of black carbon particulates – commonly called soot – over North America on July 21, 2021. The black carbon data come from the GEOS forward processing model, which assimilates data from satellite, aircraft, and ground-based observing systems.

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 Times reported 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.
