I actually wonder about current co2 levels and concentration.

We’ve roughly doubled co2 in human history. Much of that in the last 100 years alone. They say that measurable drowsiness at 1000ppm and when you consider the atmospheric co2 being well above 400ppm and indoor conditions often more than doubling that i wonder if we’re not going to hit a measurable stupefaction of the world. Perhaps it’s already happening.
