You’re missing some deeply important context there, which is that those measurements are for outdoor atmospheric CO2 only.

Average indoor air quality ranges from 400-1000 ppm CO2, with adverse mental effects starting to appear close to 2000 ppm.

In that context, you can see why a 50 ppm difference is marginal. This is why asking an LLM is not generally a great idea for understanding something - you need to follow it up with more research.



> adverse mental effects starting to appear close to 2000 ppm.

cognition is harmed starting at 1000ppm (https://pmc.ncbi.nlm.nih.gov/articles/PMC3548274/)


I'm having a hard time parsing the data in this paper - is it showing that task focus increases at 1000ppm compared to 600ppm CO2 exposure?
