Bill McKibben, founder of the environmental activism group 350.org and author of several books, including Oil and Honey: The Education of an Unlikely Activist (Times Books, 2013), offers his top 3 solutions to climate change.
McKibben said the most salient solution in combating climate change is building a movement to influence public and political opinion.
"I think history indicates that there's no way to do that without changing the zeitgeist, without having some leaders step up and say, 'This is job one; this is where we're going to put all of our emphasis from this day on,'" he said. "That's what the last three or four years of movement-building around the world has been about. You'll remember the remarkable work that activists around New York did to make sure that Governor Cuomo had no choice really but to block fracking in the Empire State."
