What is also true is that the CO2 and other greenhouse gasses warm the earth the same way. Not in the same way as a greenhouse no. You still don't understand this. Visible light from the sun can pass through these gasses, the light strikes something near the surface where it is absorbed and some of that is re-emitted at a lower frequency that does not easily pass through the greenhouse gas. Actually most of passes through the greenhouse gas. If it did a clear jar of CO2 would get very hot. But when I had a plastic container full of CO2 it was not noticably warmer than other nearby objects. Conduction and convection near the surface help this heat to blow around the troposphere, but conduction and convection is greatly reduced between the troposphere and stratosphere, thereby keeping the heat in the troposphere for a considerable length of time. Again I am not sure what you are trying to say here. I think you are confusing heat with temperature again. At higher elevations the temperature is lower simply because the air is thinner, but that does not prevent heat exchange. Also you seem to think there are clear lines between the various man made names of the atmosphere, these lines are imaginary.
