Few people are doubting that. The issue is that
> millions will die due to extreme weather
and due to climate-related wars, and life in general will become less pleasant. Just breathing air with higher CO2 concentration already isn’t that great.
- hartator 2y ago> Just breathing air with higher CO2 concentration already isn’t that great. Or less O2. I wonder if there any study that does show any impact already or these are still speculations?
- Filligree 2y agoThere isn't less O2. Even if all plants on earth disappeared (and animals somehow survived that), it would take millions of years before there's any measurable impact on O2 concentrations. Moreover, there's no physiological impact whatsoever until you drop several percent.
- hartator 2y agoO2 does decrease and is measurable: https://www.oxygenlevels.org/ https://www.oxygenlevels.org/ I think this is a more marketable concern than CO2 as without O2 most know that you can’t live.
- nradov 2y agoThose are meaningless changes. It's less than the effect of walking up a small hill in terms of inspired oxygen partial pressure.
