This summer's devastating wildfire season has sent smoke across county, state, and even international borders, affecting air quality thousands of miles away from the flames. Host Emily Gracey dives deep into the science behind the haze, exploring why wildfire seasons are stretching longer each year and how a changing climate is literally adding fuel to the fire.

You'll discover the invisible dance between smoke and weather systems that determines whether your city wakes up under clear skies or a blanket of particulates. Climate Central's Shel Winkley explains the wildfire-climate connection, while Michigan meteorologist Alec Kownacki makes sense of those color-coded air quality measurements on your phone – what they really mean, how they're calculated, and why the difference between "moderate" and "unhealthy" could determine whether you take that morning jog or stay inside.
