Hot and Bothered: What's driving the extreme heat?

We're at a point where "record-breaking heat" has become a broken-record phrase. Year over year, we hear how many parts of the world have reached a new temperature high. And just days into summer 2026, things already ramped up, with intense and deadly heat waves gripping much of Europe, where temperatures pushed near 50 degrees. And North America hasn't been exempt, as July brings in a new wave of brutal heat. Today on The Big Story, host Caryn Ceolin speaks with City News' Chief Meteorologist Natasha Ramsahai about why the heat is ramping up, how it's going to affect you, and what we can do, if anything, to stop it. We love feedback at The Big Story, as well as suggestions for future episodes.
