The Climate Change people are getting more and more desperate to be taken seriously.  You can tell because their claims are getting more and more ridiculous.  Check out the caption of Leonardo DiCaprio's upcoming movie.  This is apparently "Mankind's Darkest Hour."  Perhaps you hadn't noticed.  Black Plague?  That was nothing compared to today's situation.  World War two?  A relative picnic in the park. 

It's difficult for me to believe this sort of approach is helping their cause.
