Yesterday I checked out David Wallace-Wells' book The Uninhabitable Earth. Here's a bit I just read from it, verbatim (on pages 58-59):
"With CO2 at 930 parts per million (more than double where we are today), cognitive ability declines by 21 percent.
The effects are more pronounced indoors, where CO2 tends to build up--that's one reason you probably feel a little more awake when taking a brisk walk outside than you do after spending a long day inside with the windows closed. And it's also a reason elementary school classrooms have been found by one study to already average 1,000 parts per million, with almost a quarter of those surveyed in Texas over 3,000--quite alarming numbers, given that these are the environments we've designed to promote intellectual performance. But classrooms are not the worst offenders: other studies have shown even higher concentrations on airplanes, with effects that you can probably groggily recall from past experience."
