I wish some one would step up to the plate and put proof behind the global warming pile of cow pop. But right here is $500,000 if you can prove it is man made. I would think that at least a good university would have clamed this prize by now if it was true.

If you look at the facts on the rotation of the earth then you might see a different thought on what is causing it. Look into the part of where the North Pole dose not stay in a constant rotation with the earth. Why else dose the North Star change every year by a constant amount? Do you think that the gravitational pull because the distance changed could cause the North Pole to move?
In 1999 there was a going to be a global warming conference in the city. It was postponed because of bad weather. We hit a total of half an inch of snow that day.
