3.3.4 Atmospheric greenhouse effect after Stichel (1995)
Stichel (the former deputy head of the German Physical Society) stated once [134]:

Now it is generally accepted textbook knowledge that the long-wave infrared
radiation, emitted by the warmed up surface of the Earth, is partially absorbed
and re-emitted by CO2 and other trace gases in the atmosphere. This effect leads
to a warming of the lower atmosphere and, for reasons of the total radiation
budget, to a cooling of the stratosphere at the same time.”

Disproof: This would be a Perpetuum Mobile of the Second Kind. A detailed discussion
is given in Section 3.9. Furthermore, there is no total radiation budget, since there are
no individual conservation laws for the different forms of energy participating in the game.
The radiation energies in question are marginal compared to the relevant geophysical and
astrophysical energies. Finally, the radiation depends on the temperature and not vice versa.

In part, this says that any given CO2 molecule may or may not re-radiate energy it has gained from either thermal contact or IR influence. It may just bump a nearby molecule and lose its excess energy to some other gas. If it does re-radiate, it will be in some random direction, possibly back to space, possibly sideways, possibly down. This does not permit any kind of averaging computation.
