CO2 is busted as a cause of heating so now they’re going for a loss of water vapor as the cause for cooling? Wrong, water vapor, like CO2, is a trailing indicator of temperature change. ISS (It’s the Sun Stupid).
I believe you make an excellent point there. That’s why dew forms overnight and condensation appears on a glass of cold liquid. It’s not the dew that causes the temperature to drop, nor the condensate that makes the glass cold.
