Naomi Klein on climate strikes, Greta and the Green New Deal

Millions of climate strikers all across the world took to the streets on Friday and there's another major climate protest planned for next Friday, too. Today on Front Burner, we talk to Naomi Klein, author of the new book On Fire: The Burning Case for the Green New Dealabout Greta Thunberg, the Green New Deal, and why she thinks mass mobilization around climate change may be the only thing that can help us avoid global warming's most devastating effects. "If you don't believe in social movements, and if they make you kind of queasy and they seem kind of messy, then you should feel really pessimistic, because it's actually our only hope."
