"Global Warming" is the biggest and, so far, most successful con of the new century! So many people have fallen for it because they "don't really understand science" and because they habitually put their trust in the public pronouncements of celebrities. Sad, but that is where we are.
I recall hearing Gorbachev say that when the Soviet Union fell the Commies moved to the enviromental movement. Reason enough not to trust those global warming nuts!
