Atmospheric CO2 and the Lapse Rate: No Effect
The notrickszone site has a post by a Japanese scientist that says CO2 "climate sensitivity" (defined as the temperature increase to be expected from a doubling of CO2 in the atmosphere) is currently overstated, even "meaningless", because increasing the CO2 would change the temperature "lapse rate" in the atmosphere. My response:
All scientists should know by now that my 2010 Venus/Earth temperatures comparison already definitively showed there is no actual "CO2 global warming greenhouse effect".
Never mind doubling the CO2. The Venus atmosphere has over 2400 times the concentration of CO2 as does Earth's (that is 11.4 doublings of CO2, not just one doubling), without ANY effect upon the temperature at any given pressure level.
Further, since that Venus/Earth comparison precisely confirms the Standard Atmosphere model for Earth's troposphere as the true, stable equilibrium state of the atmosphere, it also confirms the physics behind that model, which is just that of the hydrostatic condition, that the pressure at any level in the troposphere is just the weight of the atmosphere above that level. And since the hydrostatic condition provides that the lapse rate MUST BE just -g/c, where g is the acceleration due to gravity and c is the effective specific heat of the atmosphere, the lapse rate has ESSENTIALLY NOTHING to do with the CO2 level in the atmosphere (certainly not in the trace amounts found in Earth's atmosphere, and even between Earth's .04% and Venus's 96.5%, as the Venus/Earth comparison I performed showed).
I have yet to come across ANY "expert", like the above author, who knows what they are talking about. The Venus/Earth temperature comparison makes them all appear incompetent.
