Since the time of the great physicist Maxwell to the present day, a few skeptics have noted that the primary source of the greenhouse effect is due to the effect of a gravity field upon adiabatic gases (both IR-active and non-IR-active) free to convect heat and transport latent heat from the surface, which rise/expand/cool until equilibrated with the upper atmosphere, following which, due to their gravitational potential energy and increased density from cooling, subsequently fall/compress/warm back to the surface.
This adiabatic expansion/compression process of all atmospheric gases repeats ad infinitum to create the adiabatic lapse rate/temperature profile of the entire troposphere. Radiative forcing from IR active gases is a bit player completely dominated by the thermodynamics of convection, evaporation, and the ideal gas law which are the real causes of the real ~33C greenhouse effect, not radiative forcing from greenhouse gases.
As demonstrated by a paper in Nature by Robinson & Catling, convection/adiabatic lapse rate controls the radiative-convective equilibrium and tropospheric temperature profile of all planets in our solar system with thick atmospheres. The troposphere ends at about ~10,000 km where the pressure = 0.1 bar, at which point the atmosphere is too thin to sustain convection, and radiative forcing from greenhouse gases takes over to cause cooling of the stratosphere and beyond to space.
The greenhouse gas water vapor DOES have a profound effect upon climate, slowing of cooling at night and slowing of warming during the day. The wet adiabatic lapse rate is only one-half the dry adiabatic lapse rate, proving that water vapor has a large negative-feedback cooling effect, not warming effect, on climate.
Here's one of many such explanations recently published in the French magazine Contrepoints by French scientist Jacques Henry (Google translation from French):
