Considering 15 ppm O3 in the ozone layer capture 98% of UV coming into stratosphere, CO2 is heavy and mainly in the troposphere where air is much denser so I would say 10 ppm CO2 capture 99% of IR. So 10 ppm CO2 and 1000 ppm CO2 probably wouldn't have any noticeable difference to temperature.

The ozone layer, our Earth's sunscreen, absorbs about 98 percent of this devastating UV light.

The total mass of ozone in the atmosphere is about 3 billion metric tons. That may seem like a lot, but it is only 0.00006 percent of the atmosphere. The peak concentration of ozone occurs at an altitude of roughly 32 kilometers (20 miles) above the surface of the Earth. At that altitude, ozone concentration can be as high as 15 parts per million (0.0015 percent).

Tia, CO2 does not "capture" anything. Can you ask your question without using any variants of "capture"?
