- The absolute value the heat energy emission from a radiating body cannot be determined by experiment. An experiment can only determine the surplus of emission over absorption, with the absorption determined by the emission from the environment of the body.
- However, if one has a formula for the emission as a function of temperature (like Stefan-Bolzmann's Law), then the absolute value of the emission can be determined, but such a formula has only a hypothetical meaning.

Josef Stefan: Backradiation and DLR Pure Fiction!!
Josef Stefan 1879: Backradiation and DLR is pure fiction!!
Let us quote from Josef Stefan's On the Relation between Radiation and Temperature from 1879 (my translation of page 411):
We see that Stefan understood very well that only the net/surplus has a physical meaning.
Stefan would thus say that the mantra of CO2 alarmism of backradiation or Downwelling Longwave Radiation DLR from the atmosphere to the warmer Earth surface, is pure fiction.
Are CO2 alarmists relying on Stefan-Boltzmann's Law willing to listen to what Stefan has to say? Or can the work of a dead scientist be misused at will without any consequence?
