"I spray roundup on my driveway. The weeds die. Next year, some more weeds grow back. Because the weeds grow back and I didn't do anything to cause it, I must not have killed them in the first place."
Put that way, it's pretty stupid, isn't it?
The ozone hole, and how it's caused by chemical reactions on the surface of ice particles in the stratosphere, is no longer even mildly controversial, guy. Limbaugh is a brilliant political polemicist; he should avoid pontification in the area of atmospheric chemistry, where as far as I know he doesn't have much expertise. There isn't that much ozone up there in the first place, and if you put a source of atomic chlorine into the stratosphere, in the presence of particles upon which it can react with ozone, it will destroy the ozone.
Most 'environmnetalists' are indeed chicken-littles; there is a great deal of total b.s. talked by tree-hugging types, and he's right that many of these people really are ideologues who true goal is to make the rest of us live according to their particular notion of a harmonious life. But that doesn't mean that all environmental science is b.s.. Problem is, to tell the b.s. from the legitimate science, you really do need to know some science, and most people, on both sides of the issue, are not willing to do the hard work to learn science. So they toss idiotic slogans at each other, and when Rush does it, he's no better than the tree-huggers.
We've got to go back to something called the Big Bang, and then we've got to try to make guesses as to we were all spermazoid, promozoics.
This is gibberish. As I said, he looks like a fool when he says this sort of thing. If I were a liberal trying to convince scientists that conservatives are idiots, I'd play Rush's words here at them, without comment.
