Global warming is a bunch of crap and I can prove it.
Dinosaurs, millions of years ago cold blooded reptiles dominated the planet. Giant asteroid comes and hits near mexico, or volcanos or something else got spewed into the atmosphere. Earth cooled down a lot. The dinosaurs died, even the ones living in places like: the Gobi desert, the mountains of Utah, South Dakota, Antartica and other places that they have found fossils.
Later
Huge woolly mamoths roam the plains of America, Siberia and as far down as California. Ice covers much of the world and huge glaciers carve the American plains flat. New England is scraped off and little more than rock is left. The ice starts to melt because the dust is settling. The sun comes out. Woolly mamoths, mastadons, saber tooth tigers, giant sloths, little horses, dire wolves and huge bears die because it is no longer cold enough and they get too hot.
fast forward to today.
We look at the blink of an eye in time and say it is getting warmer. Of course it is, it is going back to the temperatures of the dinosaur days, they natural state of the earth. DUH!
