The previous posts lead us to view the thermodynamic action of the atmosphere to be similar to that of a refrigerator:
#Evaporation at the ocean surface driven by incoming radiation generates cooling of the warm atmosphere above the surface.
#Warm air rises by buoyancy under expansion and cooling to TOA where it releases heat by condensation for further radiation to outer space.
#Cool air descends from TOA under compression and warming completing a thermodynamic refrigerating cyclic process.
In addition, some incoming heat is returned by radiation. If the radiation is blocked, more or less, by greenhouse gases, the refrigerator process must intensify to maintain heat balance. This requires more evaporation and thus more cooling of the atmosphere above the ocean surface.
The atmosphere will thus act like a refrigerator giving additional cooling under increased energy input.
More greenhouse gases will thus cause global cooling!
