Percentage is irrelevant. You need to look at absolute amount of greenhouse gases.You ask that as if to state that the composition of the atmosphere has no impact on surface temperature. That is especially so since you follow with:
What are the characteristics of each of those various gases with respect to infrared radiation?
Look at Carbon 0.04%? If you think that minute trace element would possibly make any difference to world climate, then you must also believe homeopathic remedies work as well!
If you take all 0.04% of CO2 and liquefy it, it would be roughly 4mm of liquid CO2 over the atmosphere which is a gigantic amount of matter capable to blank selected regions of spectrum
N2, O2, are two atom molecules and as far as infra-red concerned are 100% transparent.
H2O and CO2 are three atom molecules and because of that have additional degrees of freedom which are conveniently located in infra-red region corresponding to average surface temperature.
Astronomers have to launch their telescopes into space because of CO2 and H2O.
I was taught science as experimentation and observation not imputing computer modeling to get a desired result as is done by 99.9% of so called " climate scientists!"
By the way, I'm still waiting for just one catastrophe as predicted by the alarmists to befall the earth because of GW/CC over the last 40 years! to have come to pass. Just one!
So Far the global warming activists have a batting average of 0.000 in the predictions of GW/CC calamities. They literally haven't gotten a single prediction right yet. Doesn't that sow at least some sliver of doubt that is because there is no GW/CC crisis?
