In the greenhouse, the gas atmosphere can be totally neglected. It is irrelevant. The "atmosphere" in the greenhouse is the glass. If you don't understand this, make a simple estimate of where the % of incoming heat (radiation) ends up. Very near zero goes to the gases in a greenhouse (assuming you are using even half-way reasonable numbers). Both a well designed greenhouse and the earth are in convective and conductive isolation. That is what is so stupid about the claims of convection "heating" the greenhouse. If you don't start with the correct assumptions about the model, you end up with stupid conclusions. The claims that a greenhouse is "heated" by keeping the cold air out, is like claiming a hot air balloon rises by releasing the ropes. Both statements are true in a very literal sense, and both totally idiotic in terms of explaining the underlying science.
