While elevated CO2 levels seem to be affecting certain cognitive abilities, I did not find definitive results indicating that this has become a general problem.

There is a meta review that indicates additional research might be worthwhile / required ( https://pubmed.ncbi.nlm.nih.gov/32557862/ ).

Do you have any sources worth looking into?

Sorry I don't have good sources. I just read this a few years back with one study showing there is already an effect.

While you'd probably need to study this further to be 100% certain, I don't think it's much of a stretch to assume ventilation is going to work worse because a constant air exchange would move concentrations towards 400ppm instead of 280ppm. So the median (or whatever) can be higher than 100ppm difference. Or maybe I'm getting this wrong?

Ventilation definitely helps. I mean, I'm not doubting the effects, I actually run sensors in my office and have personally experienced "mind fog" when I ignored the readings for too long and didn't open the windows when it was time.

I was just wondering if we're already at a point where environmental changes have made this one additional problem we need to think about more.

I think we have to assume it's already affecting people. The sensors are a good idea, I definitely should get some for arduino.
