“Joel, I don’t think people are confused by the concept that, given the same amount of heating, things which are already warm get hotter than things which were colder.”
I am.
If one had no or 1/2 greenhouse affect how cold would a nite be?
That is one question. Next question is concerning ground temperature.
Take sand, grass, dirt, water, whatever, and use measure of there temperature as being the temperature [normally temperature on earth is air temperature in the shade, but air temperature is meaningless on the Moon. And want to compare the moon [has zero greenhouse affect] with earth. So second question is what would surface temperature on earth at nite be if no greenhouse effect.
