The way we talk about climate change needs to, well, change. Everything is either invisible, like emissions, or incomprehensible, like megatonnes, or inconceivable, like reductions of national emissions 25 years in the future. The cause of climate change is simple: it's fire. To end global warming, we need to stop burning things.   Guests: Tim Stezik of Toronto Fire Services, Lytton fire survivor and author Meghan Fandrich and Pulitzer Prize finalist and author of Fire Weather, John Valliant.
