I’ll have to respond later, but this is kind of backwards. Heat loss to space by evaporational cooling at the surface and condensation warming aloft works against global warming. It is a major source of global cooling.

Water acts as a strong negative-feedback element against global warming. If the Earth gets warmer, then more evaporation happens, and more energy gets transported into the upper atmosphere to be released when water vapor condenses into rain.
