Why CO2 is Not a Pollutant
By Robert Bradley Jr. -- September 8, 2023
“… the UK Health and Safety Executive has defined safe CO2 limits for the workplace. The limit for long-term exposure is 0.5% (5,000 ppm) but for shorter encounters it is 2% [20,000 ppm]. Anything over that figure is regarded as a risk to human health.”
Skeptical Science, advertised as “getting skeptical about global warming skepticism,” posted recently on the question: Is CO2 a pollutant? Interestingly, they made the point that carbon dioxide (CO2) is not a pollutant in any sense of the word. Yes, very high concentrations in confined spaces (they provide an example) is deadly, but then so is water in a drowning. But water is not a pollutant either.
