You are totally wrong in thinking that carbon dioxide is a primary cause of warming.

Radiation in just a few spectral bands from carbon dioxide can never cause a warmer surface to increase in temperature. It can have a minuscule effect slowing down radiative cooling, but virtually all the slowing of surface cooling is by conduction at the surface-atmosphere boundary. The energy thus absorbed primarily by nitrogen and oxygen molecules subsequently finds its way by diffusion into water vapor, carbon dioxide and other radiating molecules, all of which act like holes in the nitrogen-oxygen blanket, radiating energy out of the atmosphere.

There is no need for any warming by radiation anyway. It is now well-known and proven empirically that gravity forms a thermal gradient at the molecular level in the tropospheres of any planet with a significant atmosphere. On Earth the surface temperature would be a few degrees hotter if there were no water vapor, but it is cooler because water vapor and other radiating molecules (carbon dioxide included) help to cool the lower troposphere by radiating energy to higher altitudes and to space.

That is what physics tells us. From my reading of what climatologists have assumed, I find their writings to be a complete travesty of physics.
