The chart in the article you linked to shows that currently, the level of CO2 in the atmosphere is 0.04% of the air we breathe, and that lifetime symptoms of hypercapnia do not appear until that number is 1.0%.
That means that CO2 levels would have to increase 25 times their current level in order for your fear of hypercapnia to become a problem.
- pmontra 4y agoFrom https://en.wikipedia.org/wiki/Carbon_dioxide#Below_1% https://en.wikipedia.org/wiki/Carbon_dioxide#Below_1% > A study of humans exposed in 2.5 hour sessions demonstrated significant negative effects on cognitive abilities at concentrations as low as 0.1% (1000 ppm) CO2 likely due to CO2 induced increases in cerebral blood flow. Another study observed a decline in basic activity level and information usage at 1000 ppm, when compared to 500 ppm. With some caveats about the quality of those studies.
