The 2023 United Nations Climate Change Conference, or COP28, begins this week in Dubai. A new topic on the agenda this year is how wildfires are emerging as a serious health risk not just to those in their immediate vicinity, but even to people thousands of miles away. Last summer, smoke from Canadian wildfires drifted not only as far south as the mid-Atlantic region of the United States, but even across the Atlantic Ocean.

We speak with John Vaillant, whose book Fire Weather: A True Story from a Hotter World recounts a 2016 wildfire in Fort McMurray, Canada that dislocated tens of thousands of people and caused billions of dollars in damage. That natural disaster seemed like a terrifying outlier when Vaillant began his reporting, but 2023’s unprecedented fire activity suggest that Fort McMurray was merely the shape of things to come. John explains how climate change is making wildfires hotter and harder to contain. Next, we’re joined by photojournalist Andria Hautamaki, who observed a “prescribed burn” in Plumas County, California. Andria shares how these kinds of carefully planned, intentionally set fires can be a useful tool for preventing more destructive blazes.

Andria’s reporting for her wildfires story from the April/May 2023 issue of Smithsonian was supported by the Institute for Journalism and Natural Resources.
