Please review the hundred or so references in the HITRAN spectral database that quantify in detail the absorbtion spectrum of CO2.

That's been presented to jc before. He says those hundred papers don't count. Because he says so. He doesn't need any other reasons.
We've shown him many other experiments. jc says they all don't count. And never gives a reason. jc, along with Billy, just declare the last century of physics never happened, and they're sticking to that purely out of religious faith.
At this point, jc tends to run for cover by lying about the Koch experiment. Even his own source says he's full of shit, so jc pretends not to have seen that part of his source. This would be what jc always deliberately leaves out.
The Carbon Dioxide Greenhouse Effect
---
These measurements and arguments had fatal flaws. Herr Koch had reported to Ångström that the absorption had not been reduced by more than 0.4% when he lowered the pressure, but a modern calculation shows that the absorption would have decreased about 1% — like many a researcher, the assistant was over confident about his degree of precision.
(9*) But even if he had seen the1% shift, Ångström would have thought this an insignificant perturbation. He failed to understand that the logic of the experiment was altogether false.
The greenhouse effect will in fact operate even if the absorption of radiation were totally saturated in the lower atmosphere. The planet's temperature is regulated by the thin upper layers where radiation does escape easily into space. Adding more greenhouse gas there will change the balance. Moreover, even a 1% change in that delicate balance would make a serious difference in the planet’s surface temperature. The logic is rather simple once it is grasped, but it takes a new way of looking at the atmosphere — not as a single slab, like the gas in Koch's tube (or the glass over a greenhouse), but as a set of interacting layers.

jc, discuss the science. It's not honest to present an argument, and then deliberately leave out the next paragraphs that show the fatal flaws of the argument. That sort of chronic dishonesty is why nobody outside of your cult gives you the time of day, and never will, no matter how often you lie about not being shown the experiments.
Now, if you'd like, we can go over again how you and Billy lied your asses off about the mythbusters experiment. Shameful indeed, your behavior there was. It's a wonder you're still willing to show your faces here.
Also, if you'd like, we could point out the staggering stupidity of asking for a quick lab experiment that instantly predicts the temperature change on earth over many decades. Even rudimentary intelligence and common sense would have someone understanding how stupid that demand is, so only the most brainless religious fanatics make that demand.
