re: #565 Buck

It is a great THEORY… but there is NO EVIDENCE anywhere that CO2, Man made or otherwise drives the climate.

Carbon dioxide is a strong greenhouse gas.

Consider this: The atmosphere on Mars is 95% carbon dioxide. Despite the fact that Mars is another 50 million kilometers farther out and the atmospheric density of Mars is 1/100 that of earth, the surface temperature of Mars at the equator occasionally exceeds the freezing point of water.

In my opinion, greenhouse-effect skepticism has a lot in common with evolution skepticism.
