Quantifying the Relative GHE for Various Planets
In a previous post I debunked a silly paper from Holmes that claimed to be able to calculate the 1-bar temperatures of a planet knowing only the ratio of the TSI values for the two planets and the 1-bar T for the second planet. Holmes' used the following equation. T1 = ∜rTSI*T2 I showed that this equation doesn't work because it ignores both the GHE and albedo. It gives the superficial appearance of working if you calculate 1-bar T of Earth from Venus and vice versa, since Venus has both a strong albedo and GHE. But even then it only "works" if you use 340 K for Venus' 1-bar T, and NASA currently reports the 1-bar T for Venus to be 360K. And this formula doesn't work for any of the possible calculations involving Titan at all, so it has at best a 67% failure rate (if you accept 340 K for Venus). One thing I thought was interesting, though, is that if you use ASR instead of TSI, the results were still wrong, but they were wrong in such a way that indicated the...
