Where do you get that? If you will look at the spectrum in the first graph in my reply you will notice that the peak of the radiation from the Sun, at the top of the atmosphere is in UV and visible? The level in the CO2 absorption bands is a whole lot lower than the level in the UV and visible.

And of course I'm still not sure why Venus is so hot if CO2 cools things off.
