>Is it radiative spectroscopy that tells us how much heat is being emmited by the CO2 in the atmosphere?
Again, a very weak greenhouse gas. Deal with it. The effect of water vapor is MUCH stronger and almost completely covers the absorption spectrum of CO2.

>Is it the isotope analysis that tells us we are the only net source of increasing CO2 in the atmosphere?
The half-life of anthropogenic CO2 in the atmosphere is only about 5%. Why? Because it's atmospheric half-life is about 5 years. And the ocean is a much larger sink for CO2 than the atmosphere.


And look at the B Bolin, E Eriksson - The atmosphere and the sea in motion, 1959, specifically.
P. 133, "...any excess CO2 put into the atmosphere will ultimately be distributed so that about 11/12 of it goes into the sea..."


Pic related (Jaworski 1997a), almost no correlation between the flux of anthropogenic CO2 and the increase of CO2 in the atmosphere.

Quantum mechanics is hardly a "supposed effect." The quantification of absorption to specific wavelengths is not in dispute. But see the attached graph for the absorption bands of various greenhouse gases. Notice that CO2 has only a couple of narrow bumps. Outside of that range, it is IMPOSSIBLE for CO2 to absorb electromagnetic radiation. Once the radiation from those wavelengths are absorbed, there is nothing more that it can do.
