The models include this at a high enough level to provide reliable predictions of temperature profiles. It appears that you are confusing convections with radiation here. This should not effect radiative losses. The next to last sentence is fundamentally dishonest. It puts global warming on the same basis as a runaway greenhouse effect.
NONE predict a runaway greenhouse effect.
As Tobis pointed out to you there is no doubt that CO2 and trace gas concentrations are increasing. Long searches for additional non-anthrogenic sources, or unknown sinks have failed. Calculations of anthrogenic releases of CO2 and other trace gases such as NH3 and CH4 agree with measured increases. Basically, denying this makes you look like an idiot with his thumb up his nose. What Tobis was telling you is 1.
