If you live anywhere near the Great Lakes or Mid-Atlantic (or certain parts of the Mountain West), odds are it’s smoky where you live. Wildfires raging in western Ontario are sending smoke cascading south and east across the U.S., prompting widespread air quality alerts affecting millions of Americans.
The good and — very bad — news is that we’ve been here before. Here’s a look back at some of Heatmap’s coverage from the summer of 2023, when smoke produced by forest fires in Quebec blanketed 128 million people in a murky haze and turned the New York City skyline an ominous shade of orange.
One day — even just one hour — of smoke inhalation can exacerbate pre-existing health conditions and increase an individual’s chance of premature death by 12%. To stay safe, Jeva Lange recommends avoiding prolonged outdoor exposure and masking up when you go outside.
Wildfire smoke is full of tiny pollutants that can leak into your apartment even when the windows and doors are sealed tight. That’s where air purifiers come in, Matthew Zeitlin writes.
Tinted skies are now a rare, remarkable event. But decades ago, before targeted policy interventions, this was everyday life for New Yorkers. Here’s Jeva with more on the legacy of the Clean Air Act.
Before you step out for a run, read Emily Pontecorvo’s guide to what the Air Quality Index is and isn’t telling you.
People should not inhale smoke because of its dangerous health effects. But plants, interestingly, may actually thrive. Allow Jeva to explain.
