AMERICA IS ON fire … again. More than a million and a half acres are burning in 15 states, from Arizona to Alaska. More than 3,000 firefighters are working to contain the Mendocino Complex Fire 100 miles north of San Francisco, now the largest in California history, and over the weekend, lightning strikes sparked dozens of new wildfires across the state of Washington. Near Mount Shasta, the deadly Carr Fire has so far incinerated 1,077 homes, forced mass evacuations, and killed eight.
Putting a few hundred miles between you and combustion country certainly confers some measure of safety. But not as much as you might think. While wildfires are geographically limited by nearby fuel sources, wildfire smoke goes wherever the wind takes it. Carried on eastward-flowing air currents, dangerous particulate matter from wildfires is increasingly smothering large swathes of the US, causing health scares wherever these air pollution spikes hit. Welcome to the United States of Smoke.
