TWTW begins with a brief discussion of the second law of thermodynamics because some scientists claim that the greenhouse effect violates it.

It Does !

No spectral filtering can create and sustain an energy , ie: temperature , gradient .

The reason and amount by which bottoms of atmospheres are hotter than their planet's radiative equilibrium , determined by its distance from the Sun and the correlation of its Schwarzchild spectrum ( color ) and that of the Sun's power spectrum , is the adiabatic tradeoff of gravitational , potential , and kinetic , thermal , energy keeping total energy constant as required by Conservation of Physics .
