The amount of oxygen in the air is hardly changing and would support human life easily after climate change goes bananas. The amount of CO2 that is causing climate change is actually quite tiny even though it doubled or tripled since pre-industrial times. It’s still far less than 0.5% (the safe recommended amount) of the atmosphere. You could triple the current CO2 levels, which would be devastating for the climate, and still breath perfectly fresh air.

I think “perfectly fresh air” is a bit subjective here lmao but I get what you mean
