Correct. And what a lot of Leftist pseudoscience fails to note is that global warming began at the end of the Ice Age. And lo...humanity didn't have coal-burning plants or the internal combustion engine at that time!
This whole "global warming" nonsense is nothing but one more reason why science should never be handled by committee.
As someone pointed out on another thread, global warming is like the acid rain of the late 70's and 80's. I remember when I was in elementary school I was scared out of my mind by acid rain. I wrote this story (please forgive me I was in 4th grade) about how humanity had to retreat to underground cities in order to save themselves from the ravages of the dread acid rain. It was a tragic tale of man's absoulte disregard for the environment and also a streaming pile of politically correct bullsh*t. In any case, apparently the impact of acid rain wore off so now we are onto global warming - some kid is probably writing an essay at this very moment.
