Because if the types are correct, it’s mostly bug free already, right?

AFAIK without any greenhouse gasses the temperature would be about -18 °C so 20% of about 45 is 9° C which is a drop from +25 to about +16 which is quite cold but not exactly humanity ending cold, right?

I assume that the other greenhouse gasses would still be plenty good at their job. Why do you assume that the drop would be catastrophic?

Still makes the world better, just not for humans ¯\_(ツ)_/¯

Remove the ability of carbon dioxide to act as a greenhouse gas.
