DescriptionUPDATE: (See comments for discussion of changes below)

FWIW the idiocy du jour is that thermal energy is not heat. Thermal energy is heat. Joule showed that about 150 years ago

This is probably time to move on to the next section, the mystical revolving planet

The following might be inserted into the introduction (from Robert P):

Gerlich and Tscheuschner [1] assert that Clausius' statement of the second law of thermodynamics forbids transfer of energy from a colder atmosphere to a warmer surface. As shown in Section (3.9), the second law requires consideration of all heat flows in a process, so one must also include the transfer of thermal energy from the surface to the atmosphere. Ref. 1 does not consider this second part of the process and thus errs. When done properly, there is no contradiction

The fundamental equations of radiative transfer have the Second Law of Thermodynamics built into them, via Kirchoff's Law, which can be derived directly from the 2nd Law. Thus when solved numerically the solutions perforce obey the 2nd law. This applies equally well to simple models described below, and to the most elaborate line-by-line calculations. All show that the presence of greenhouse gases in the atmosphere results in a warmer surface than in their absence.
