No, I'm not confusing CO for CO2.
Yes, I do have sources that human mental performance suffers at elevated CO2 levels (800-1000ppm, not uncommon in buildings... but could be the CO2 level outdoors and even if it's not quite that high, it'll be harder and harder to keep building CO2 levels below that as external CO2 levels increase). https://www.nature.com/articles/s41370-018-0055-8 https://www.nature.com/articles/s41370-018-0055-8

Current levels aren't really problematic except in stuffy buildings. But if we don't stop changing the chemistry of the atmosphere, it becomes a problem.
- morpheos137 5y agoIt would be interesting if the study could be duplicated. More importantly it does not seem to distinguish between the acute effect of a sudden increase in CO2 in an experimental setting and the chronic effect of gradually rising ambient rates over the span of years. It stands to reason that the body would adapt to higher CO2 levels over longer time ranges vs. just injecting a sudden pulse of 2500 ppm into a closed chamber.
- Robotbeat 5y agoWell, good news! We’re conducting a planetwide, n = 8 billion, study on this topic right now! We don’t have a control group, though, except maybe a handful of rich folk who can afford to scrub CO2 from their penthouses.
