I don’t see how CO2 impacts warming. It only absorbs 3 narrow spectral lines in the IR spectrum. Water vapor has a very broad IR absorption spectrum that covers the three CO2 absorption frequencies. Since water vapor is abundant it would be rare that a CO2 molecule got a chance to absorb any IR and it would not change the total IR absorption if it did.
