Water vapor covers the exact same wavelengths as CO2,
Talking to yourself like this is an indication of insanity, walleyedretard, but of course, we don't really need to see any more indications since you've already demonstrated that you're completely bonkers many times on this forum....clearly your knowledge on the subject is lacking. As it is for most science hating AGW [denying] religious fanatics. You guys don't "do" science. It scares you or something.
Wait wait wait.
The wavelength of light and short wavelength infrared CHANGES after it passes through the atmosphere.
So WHICH wavelength absorption is being measured in that handy dandy little chart? The absorption of the energy on the way down through the atmosphere or the absorption of the energy (mostly heat) on the way back up from the Earth?
I am not a scientist and don't play one on TV. But I do recognize a much greater need for precision in this discussion.

I noticed that TinkerBelle had to go waaay back to the 1950s to find a chart that lopped off the most important bits of that relationship..
A more complete view of the overlap is shown here..
Note the bracket showing the band for the reflected surface heat.. If you want to treat the surface as a black body radiator (which it isn't really) than you want to know what happens primarily in the longer wavelengths..
SMALL SHIFTS in that reflected radiation band COULD modulate the amount of overlap in the water/CO2 absorption bands. As in changes in Albedo in the Arctic or contributing to other "sensitivities" that we observe REGIONALLY or seasonally...
