> Noticeable cognitive impairment starts in the 700-1000ppm range

The US navy failed to detect such effects in submarine crew, even at much higher levels like 10,000 ppm.

Another reason to be skeptical is that exhaled breath is 4% CO2 (40,000 ppm!). Therefore a few thousand extra ppm in the inhaled air should not make much of a difference to the homeostasis mechanisms in our bodies.

See my sibling comment for meta-analysis that disagrees with you. Would love to see citation for those navy experiments.

    Back in the 00’s I worked at a place where we were still ignoring WLB and would work until seven a couple nights a week on average. But the building AC shut off at 6. A few of us noticed that the later it got the worse our decisions and the worse the bickering and we eventually got to the policy that anyone could declare Deciding done for the evening when they realized we were just tired, hot, and stuffy. Every minute past about 6:15 got worse, particularly in summer.

    I’m sure the CO2 was part of it but lack of circulation also means increasing temperature, especially with a bunch of people in a small meeting room. Long meetings themselves are a problem and any excuse to call it early is probably worth it even if it’s not entirely true.
