What the heck does the heat distribution within the earth or within the greenhouse have to do with anything, other than be a source of confusion for dimwits? I already pointed out that the ratio of atmosphere to surface heat capacity inside a greenhouse is way smaller than the ratio of atmospheric heat to surface heat capacity of the earth. The effect of that is simply that in a greenhouse, the air temps is much closer to the same temp as the surface, and that any time lag is much smaller. Freaking irrelevant to the analogy. The point remains that a greenhouse which (sans convection cooling or small conduction losses) is identical to the earth in space. The energy comes in and goes out via radiation, and the greenhouse temp goes up to reach thermal equilibrium which is 100% determined by the incoming and outgoing radiation's spectrum and its interaction with the covering of the system (glass or atmosphere as the case may be).

If you really don't understand it, then use a greenhouse with a roof 100 miles high so that it has the same volume of gas as the atmosphere. Guess what, the gas won't heat bottom to top in one day either. So what?

You figured out how to heat any of these greenhouses using "convection modulation" yet?
