On June 27, 2023, a thick blanket of smoke from Canadian wildfires blanketed Chicago, pushing the city’s air quality to the worst on a global index of 95 cities. This sudden decline, according to Illinois State Climatologist Trent Ford, is an unusual scenario for a city that doesn’t have perennial air quality issues.

The result? Residents experienced headaches, discomfort, and a general sense of unease. While smoke in the atmosphere isn’t uncommon, high concentrations at the surface level, as seen on this day, are. The air quality index, which measures particulate matter and ground-level ozone, rose to a level deemed “very unhealthy,” signifying a health risk for everyone.
So, what’s causing this dramatic decline in air quality? Particulate matter known as PM2.5, tiny particles emitted by factories, vehicles, residential fireplaces, and wildfires, is the main culprit. PM2.5 can reach the deepest parts of our lungs and even enter the bloodstream, triggering health issues like heart attacks and strokes.
This hazardous air quality, according to Brian Urbaszewski, Director of Environmental Health Programs for the Respiratory Health Association, is a direct result of wildfires, weather systems, and winds carrying smoke. “We’re in the crosshairs,” Urbaszewski said, highlighting the interconnectedness of these conditions with larger Climate change discussions.
While the immediate health impacts are alarming, the long-term effects are a growing concern. With seven out of nine air quality alerts issued for the Chicago metropolitan area in June 2023 alone, it’s clear that these are not one-off events. This frequency of unhealthy air conditions, especially during summer when outdoor activities peak, has the potential to create significant public health challenges in the future.
As we grapple with this reality, the Canadian wildfire smoke shrouding Chicago serves as a stark reminder: climate change isn’t a distant threat—it’s already at our doorsteps. Now, more than ever, we need to engage in conversations about sustainability and climate action to safeguard our cities and our health.
