poor poor Eric, convection is caused by a difference in density at equal pressures. Density at the same pressure is affected by two things, The termperature and the partial pressure of H20 making up a given volume. For any two air masses of the same volume and the same pressure, the density of the air is inversely proportional to the dew point of that mass. It is also inversely proportional to the temperature of that mass except in the cases where dew point dominates. See Density Altitude Calculator. pilotoutlook.com The the lift of that air is the ratio of the delta density. Theoretical dry air being the most dense. Why don't you read about Density Altitude. en.wikipedia.org The tiny change is air density by increasing the density of theoretical dry air causes more work lift potential than the supposed non existence increase in radiative forcing by CO2. In addition the absorption gradient of said increase, increases the thermal effect of said change and that also increase the lift potential. Consider a plate in a microwave. A drop of water at it's center. The water heats, and that heats the plate locally where the water is. the rest of the plate remains cool. In the same manner CO2 would heat air in a smaller volume closer to the emitting surface.
