If there's cloud cover, the heat is trapped by water vapour and the temperature stays warm. If you go to In Salah in southern Algeria, they recorded at noon 52°C. By midnight, it's -3.6°C.
Yes you are absolutely right! And the fact that CO2 is the same in all locations makes a nonsense of the whole CO2/climate worry. It is water vapour and clouds that by far dominate climate through clouds as well as water greenhouse insulation effect. Clouds can both cool (low level) and warm (high level cirrus)- this is where the important and exciting climate research is going on- the behavior of clouds and their impact on climate. Adding a small amount of CO2 to the atmosphere will have a barely measurable effect on climate, even if you double CO2.
