In today’s Big Story podcast, first of all, what is a heat dome? How rare is it? How deadly? Are the all-time high temperatures the Pacific Northwest experienced this week an anomaly, or a terrifying glimpse of the new normal?
Can we pin this all on a warming climate? Or is some of it an unlucky combination of weather systems? And if this is a sign of things to come, what do Canadians, and governments across the country, need to do to prepare for summers to come?
GUEST: Katharine Hayhoe, climate scientist
