CO2 is very well understood. Even from the context of co2 is a weaker ghg than H2O, co2 is the stabel gas in the atmosphere and drives the average level of H2O in the atmosphere. We have our past level of climate thanks to co2. More is better doesn't go well with me during this heat wave we are having now. With increased co2 emissions rather than less, warmer gets ugly real fast.
http://www.skepticalscience.com/radiation.htmlSo please explain why Relative Humidity levels have been decreasing while the lapse rate feedback appears to be positive?
[color=#408000]Are you avoiding absolute or specific humidity?
Lapse rate is a negative feedback. It appears that lapse rate will slow down the ghg effect.

Lapse rateMain article: Lapse rate
The atmosphere's temperature decreases with height in the troposphere. Since emission of infrared radiation varies with temperature, longwave radiation escaping to space from the relatively cold upper atmosphere is less than that emitted toward the ground from the lower atmosphere. Thus, the strength of the greenhouse effect depends on the atmosphere's rate of temperature decrease with height. Both theory and climate models indicate that global warming will reduce the rate of temperature decrease with height, producing a negative lapse rate feedback that weakens the greenhouse effect. Measurements of the rate of temperature change with height are very sensitive to small errors in observations, making it difficult to establish whether the models agree with observations.[57][58]
