Carbon dioxide does NOT form aggregates. It is not lighter than air and thus does not rise quickly. There is no phase change when carbon dioxide enters the atmosphere. Carbon dioxide carries less than half the heat per molecule compared to water. One gram of Carbon Dioxide heated at the surface by incident sunlight carries (2 * 539 = 1078) 1078 times less energy into the atmosphere than one gram of water. Carbon dioxide represents 0.0387 % of the atmosphere. Water in the lower atmosphere represents 1% to 4% or 25 to 100 times the amount of carbon dioxide. Combining the two statements above, Water is (25 * 1078 = 27,175) to (100 * 1078 = 108,700) times more responsible for greenhouse effect than carbon dioxide.

That link has some things backwards. The cooling effect of evaporation at the surface and condensation at higher altitude is a countering force to the greenhouse effect, not part of it. The fact that CO2 does not condense is what gives it its greenhouse abilities.

BULLS EYE!!!!!!!!!!!!!!!!!!!!!!!!

You dah MAN!
