A week ago, it was record-breaking temperatures. In the Arctic as well as the Antarctic. This weekend, an ice shelf the size of New York City broke off one of the parts of Antarctica that's supposed to be stable. Is this another frightening sign of how quickly the climate crisis is escalating? A series of coincidences that ultimately won't have massive consequences? Or a chance for us to learn that the answer to both those questions can, in fact, be "Yes"—and that scary headlines ultimately might not be the best way to wake up the world?

GUEST: Simon Donner, professor of climatology at the University of British Columbia
