For more than a century, the Winter Olympics have depended on cold, reliable conditions. But as the planet warms, that foundation is becoming harder to find.

As the Games return to Northern Italy, this episode of Off the Radar examines how climate change is reshaping the future of winter sports. Meteorologist Emily Gracey speaks with Dr. Daniel Scott of the University of Waterloo, whose research shows a rapidly shrinking list of cities capable of hosting the Winter Olympics safely and fairly.

We explore why warmer temperatures mean more than just artificial snow, how deteriorating snow and ice increase risks for athletes, and why the Paralympic Games face even steeper challenges as competition moves deeper into warmer months.

With fewer cold places left on the map, the question is no longer theoretical. Can the Winter Olympics survive in a warming climate, and what decisions made today will determine their future?
