a wandering happenstance

@neauoire Elevated levels of CO₂ are bad for cognition, but the sustained levels where you start to see cognitive effects (above around 1200 ppm) would be historically absolutely unprecedented and would result in catastrophic global warming (RCP8.5-level, 3.0℃ to 12.6℃.

So, we’ll have to find some other way to inflict massive cognitive damage on ourselves—preferably more than one way.
