“a 15 percent decline of cognitive ability scores at 950 ppm”
Here’s a nice overview discussing research from Berkeley and Harvard on cognitive impairment with higher levels of carbon dioxide: https://

A few choice quotes from the article:
- “The Harvard group measured a 15 percent decline of cognitive ability scores at 950 ppm and 50 percent declines at 1,400 ppm.”
- “The IPCC projects outdoor air concentrations up to 1099 ppm by 2100 (much higher in cities and indoors of course).”
- “Measured outdoor CO2 levels in major cities from Phoenix to Rome can be many tens of ppm higher — up to 100 ppm or more — than the global average”
- “As a result of these studies, NASA has already lowered the maximum allowable CO2 levels on the space station.”
Cognitive impairment presents a potentially untapped angle on the changing climate and rising carbon dioxide levels.
Please recommend a cheap, portable carbon dioxide meter! Comment below, 10 ppm accuracy is sufficient.
