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.
If the libs and .gov told the truth they would just say that what they really want is to control everything including the means of production.
