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.
There is very little heat actually captured by gasses in the atmosphere. That is why it is really cold up there!
The issue is the amount of energy captured at the surface and then transferred into the atmosphere as vibrational and translational energy. It is this relative ability of water compared to CO2 that generates our temperatures.
The greenhouse effect is generated by the glass keeping that energy confined. Open the windows of your car and see if it gets cooler.
