Good points: remind that the Earth is a water planet. We live on islands. Water vapor traps much more heat than CO2. The villan, therefore is humidity.
Hey east coast, stop messing with the climate.
Be careful about that stmt. I posted just about the same and had a go round with a couple freepers telling me a) the greenhouse effect isn't real (with links to dispute it) and that b) water vapor isn't a strong greenhouse gas. The person disputing water vapor wanted my sources. It is hard to say it was 10th grade space science and 12th grade astromony when we studied absoption spectragraphs and this was LONG before the internet was "invented" (by Al Gore of course).
I just quit arguing with them, not worth my time.
