I find it interesting that theoretical calculations for doubling CO2 are ~ 1C, and with watervapour corrected to temperature it gives an increase of ~1.3C. that's pretty close to what most knowlledgable skeptics and lukewarmers have been saying all along. edit- transient climate sensitivity estimates have come way down lately to ~1.3C from about 2C
I am too lazy to check the actual numbers but it seems like the outgoing radiation in the atmospheric window is increased more than other areas, which is what you would expect for GHGs thermalizing GHG specific energy into (admittedly less that perfect) blackbody radiation.
