You guys should really watch it. The global warming crowd will soon be changing their focus to some other "global" problem because the whole "man is causing global warming" will soon become obvious is a load of crap.
Greenhouse gasses don't cause global warming.....global warming causes green house gases. Funny how Al Gore didn't mention that the relation of global warming and green house gases is that green house gases don't increase until several hundred years AFTER the climate has warmed and the majority of the green house gases come from the ocean...which would make sense since the earth has had hundreds of ice ages well before man was in the picture. But...those are just facts. Also, never mind that the earth temperatures seem to follow solar activity on the sun. Just a coinky dink...right?
