Bill Illis posted a table from RealFakeClimate showing Hansen’s scenario A/B/C assumptions. What was inside was just about what I should have expected from Homer.
He is off by three orders of magnitude in his CFC numbers
The table is parts per million, but the CFC numbers are at least three orders of magnitude too high. CFC11 should be 0.00025 PPM, not 0.52
If everyone on the planet was a molecule of air, less than two people would be CFC11 molecules. CFC’s play essentially no role in the greenhouse effect, as radiative transfer models show. A 1 ppm change in CO2 is 4,000 times more molecules than a doubling of CFC11.
Hansen is completely incompetent, and apparently has been for his entire career.
