If you want to take on the powerful fossil fuel industry but you are unable to compete with it, what do you do?  You create a worldwide crisis, the evidence of which is in an area that few people have any expertise in, that relies on speculation and statistics for its support, and which few will question because of fear.   Then you overwhelm the media airwaves/Internet with propaganda that the world is literally going to end as a result of this crisis.  

Funny that many people here will mock the Communist menace that was the crisis of the 1950s, but they buy into this one hook, line and sinker.  At least there were actually Communists in the 1950s.

I suggest you all watch the movie, "Wag the Dog."  "I saw it on TV so it must be true."
