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.

Every day children are exposed to air CO2 levels of 2,000 ppm, 3,000 ppm and up in their school classrooms (Corsi et al., 2002). Somehow they manage to survive.

The one comment to the article is particularly revealing:

This wouldn’t surprise submariners, who are exposed to 4 figure PPM concentrations – for weeks or months at a time.

Indeed.

It's nice to know it's safe for me huff carbon dioxide.

If that is/was true then the schools are responsible for it, has no one in education heard of air circulation? If they are claiming these levels now what was it like when we had 50% or more students in a classroom for more time than kids are now? I'm pretty sure that the all the kids I knew turned out well and without any mental deficiencies they were not born with.
