Alright, so we pump energy into a chaotic system and obviously the extremes will get more exteme. Stronger hurricanse, colder hurricanse and snap freezes, deeper floods, wet bulb events further north than you think possible, whatever. This is the known unknown.

I am existentially afraid of the unknown unknowns. At what point do the phytoplankton I'm currently breathing the poop of have a mass extinction event? All of human civilization is about to drown on dry land and I spend 5 days a week maintaining software that charges people for turning on their lights.

I crave death I crave oblivion death to america death to capitalism death to me.

However, nobody talks about the known known: What are the effects of rising CO2 levels on human life?

Your body simply creates more hemoglobin cells to compensate for the reduced concentrations of oxygen. People living in high altitudes have crazy amounts of hemoglobin cells in their blood, and if you spend some time living there you'll adapt to it in just a few days.

Yeah but 1950s high altitude air is different from 2024 lowland air. Old High air just has less of everything in general, while new air (regardless of altitude) has 50% more CO2 specifically

CO2 is not poisonous if thats what you mean. It fucks up the environment because having more of it makes the planet absorb more heat, but it's not harmful directly like CO is.
