enlightened us thusly:


But pouring more water vapour into the air does not increase warming,
in fact if it leads to more clouds the change in albedo could have the
opposite effect ;-)


that's an unknown. water vapour is a greenhouse gas, and liberating the
carbon and hydrogen from fossil fuels adds to the current levels of CO2 and
H2O in the atmosphere.

cloud cover at night means no frost in the morning...

and although visible light is reflected more from clouds, not all the energy
arrives in the visible spectrum.
