New Studies Claim The More CO2 In The Venus Atmosphere The Colder It Gets

Early Venus is suggested to have been much colder – and thus habitable – due to higher concentrations of CO2…because CO2 drives cooling in most of the Venus atmosphere (stratosphere, mesosphere, thermosphere).
Scientists have for decades agreed it is “well recognized” that CO2 molecules radiatively cool the atmospheres of planets like Earth, Mars, and Venus (Sharma and Wintersteiner, 1990) in the 15 μm band starting from 12 km above the surface on up.

For rocky planets like Venus “adding CO2 obviously cools the whole free atmosphere” (Wang and Yang, 2022).
