Bill McKibben on Global Warming: Have We Passed The Point of No Return?

On Saturday, July 20th, I spoke with Bill McKibben the founder of 350.0rg. Prior to a terrific talk he gave to the crowd of more than 100, he spoke with me on camera about global warming. He answered my second question in this very short clip with a blunt and somber answer. The question was: do you think we’ve passed the point of no return.

Watch this short clip for his answer.
