How do we apply the Stefan-Boltzmann equation to radiative heat transfer from/to CO2 in the atmosphere?
If we can use the Stefan-Boltzman equation to quantify the radiative flux leaving a solid body due to emission of radiation and to do it properly for a solid body we need to include the emissivity ...
