Another graph that should be included is the actual energy spectrum reradiated from the earth; the relative amounts of energy in the H2O spectrum and the CO2 spectrum are important to be able to judge the reasonableness of the hypothesis.

I note that the difference in area between 380 ppm and 1000 ppm is minuscule, which suggests that effective saturation has occurred at a far lower level, which is why a 200 ppm curve would be of great interest.

Excellent graphs!

Just for giggles, I’d like to see that graph with water vapor only included at realistic levels, no CO2. Doesn’t water vapor alone also cause significant absorption in the 600 to 800 Wavenumber region?

Thanks,
Gregg

one correction: 380 ppmv is 0.038%, not 0.00038%.

Nice graphs though!

Silly me, thanks
