but in a system where CO2 is heated by the sun so it collides with other gas molecules and subject it to 140mph jetstreams, then no, it's going to mingle with every other gas up to around 80km high.

Air has greater heat capacity than CO2, air density changes with conditions(temp/pressure) to a much greater extent than CO2, so it's unlikely to rise in the same manner that air does as it's density doesn't change much with temp/atmospheric pressure, neither will its buoyancy.

CO2 insulates the planet by blocking the reflected IR from flying off into space.

I'd argue that water vapor is just as insulating as CO2 if not more so, but no one bothers to curb humidity do they....

air contains CO2? either way the reason why the density of CO2 is irrelevant here is known, for the same reason they don't tell you to put CO detectors on the floor.

For the reasonable observation is that you can't stop water evaporation, but you can reduce CO2 emissions, so let's try and fix the fixable first?

Air has a lot of things, is air a molecule like H2O? CO has similar density to air, thus it diffuses in air much more readily than CO2.

but you can reduce CO2 emissions

Yeah by not breathing, try it, see how long that works out for ya.

well it's only inversely proportional to molar mass, so not by much, air currents would be vastly more significant

Yeah by not breathing
