> Humans evolved in an atmosphere containing roughly 280–300 ppm of CO₂. The average annual increase over the past decade has been about 2.6 ppm per year, with 2024 recording a 3.5 ppm rise.

So currently we're at 428 with 3.5 increase per year, yeah, that's scary if it doesn't slow down soon. Makes you wonder about what indirect health side-effects that could have on us.

Good job we can outsource all our thinking to an agent, now.

When the wildfires during COVID hit some folks did some work to figure out how much of a cognitive effect wildfire smoke has on the brain. Its pretty staggering.

Essentially, this affects every person and animal on the planet.

Literally said this down below and got downvoted... but it's a big deal and nobody is talking about it really - indoor levels are much higher.

Exercise rises CO2 levels in blood and there are specific exercises to increase CO2 tolerance. Also, extra ventilation during very long exercises (hours) lowers CO2 blood level.

As the recovery from aerobic and resistance exercises also increase ventilation, I think we should just train a little more.

I'm not a doctor, but I reckon it'd be same as any other case of carbon dioxide poisoning.

It makes us dumber and dumber.
