  "The study did not take into account other potential influencing factors"

  420ppm seems to ignore how bad it actually is for a lot of humans. A lot of buildings have over 1000ppm of CO2 due to being poorly ventilated, levels where humans start to have noticeable cognitive decline. Spending so much time at home post COVID I got an indoor air monitor to tell me when to open the windows. 2-3 days of not ventilating will get it over 1000ppm
