And then you've got President Clinton who made the case as only he can. After he spoke, somebody sent out a tweet- they said, you should appoint him secretary of explaining stuff.

We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science-and act before it's too late.
