I'll admit that at the thermodynamic level, Wirebender has a case. Increase pressure=higher temperatures.
The sun would have to increase its output to cause a warming of the planet...A increase in energy.
Water vapor is stored heat that evaporates(taking in heat) and releasing heat in latent heat as it condenses. So it doesn't break the rule.
Water is in fact, the only gas in the atmosphere, and the only substance known to man that can absorb and retain heat and convert to its various phases in an open atmosphere.
