"This Is the New Normal": How Climate Change Is Fueling Massive Storms like Harvey

Hurricane Harvey has already dumped more than 9 trillion gallons of water on Texas-enough water to fill the Great Salt Lake in Salt Lake City twice.

We speak with David Helvarg, executive director of Blue Frontier, an ocean conservation organization, about how climate change is fueling massive storms like Hurricane Harvey.
