Study Suggests Human Exposure To 20,000 ppm CO2 Has No Effect On Cognition, Health

An observational assessment undermines claims that elevated CO2 levels are harmful to humans.
Every year there are several papers published attempting to establish CO2 as a pollutant in indoor settings. This has likely served to scare people to regard elevated CO2 levels as dangerous – which is almost certainly the intent.
For example, I have noticed that on my home CO2 monitors the facial symbol denoting healthy vs. unhealthy concentrations vary from a smiley face below 600 ppm to a frowny face when the room CO2 rises to over 1,o00 ppm…and a straight face between 600 and 999 ppm.
