Pooof, we all freeze to death.
Still makes the world better, just not for humans ¯\_(ツ)_/¯
Only if you like cold barren rock, there's plenty of those already - isn't it nice to have an interesting one with lots of stuff happening?
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?
CO2's share of the greenhouse effect is pretty significant (about 20% afaik), and the other gases wouldn't just fill the gap. So it would get quite a bit colder.
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?
Apparently it's a bit more complicated than that.
