If Co2 levels go up, plants grow faster, removing more Co2 from the air and returning more oxygen for us to breathe. So, what is the problem with higher C02 levels? It can’t trap heat, because it is colorless and odorless.
The only way to let the heat out of the earth would be to start the Freon plants back up and get a nice big hole in the ozone layer, IMHO. (This was another farce brought to us by these same global warming paranoics).
Only to a point; the CO2 fertilization effect apparently is self-limiting, and we've got plenty of oxygen.

It absorbs in the IR; it's not "colorless" in the infrared range.
