In my experience, lack of proper ventilation is a much bigger problem than background CO2 levels.
In other words, this article only holds under the assumption that ventilation stays as bad as it is. If we improve ventilation, we can get an improvement much bigger than the increase in background CO2.
The article even says so:
"In a 2002 study, researchers tested the air in 120 Texas classrooms, and found CO2 levels above 1,000 ppm in 88% of them. In 21% of the classrooms, the concentration exceeded 3,000 ppm." -- current background is ~410 ppm (possibly higher in cities) so even a doubling + better ventilation would improve the situation in most classrooms.

- Omnitaus 7y agoThey're missing something. Right below, in the same article: "As carbon dioxide levels rise, better ventilation won't be enough to protect us from its effects. "There's no way to solve this except for keep the CO2 low," Karnauskas said. "You can try to increase ventilation, but you're only going to be ventilating higher-CO2 air, because it's going up outside."" If CO2 concentrations outdoors double, you're already looking at a minimum of 1000ppm indoors.
