Busted: American Lung Association Never Mentions CO2 as Harmful to Human Health


I just finished watching Chris Wallace grill EPA director Scott Pruitt and was shocked to see the questioning of Chris Wallace. It was if he got his talking points from MSNBC or Michael Mann. The one comment he repeated were highly speculative comments made about the clean power act saving thousands of lives. To support these claims he referenced the American Lung Association’s position multiple times. I found that extremely odd. If there is any organization that understands that CO2 is not a pollution, it is the American Lung Association.  The entire purpose of the lung is to manage the delicate balance between CO2 and O2 in the human body. CO2 is necessary for the lung and blood to function. Too little or too much CO2 in the lung and the pH of the blood can change, hyper- ventilating can cause a person to lose consciousness, too much CO2 and a person can suffocate.  The standard level of CO2 in the lungis between 2.7 to 7.5%. To put that in perspective atmospheric CO2 is 400 ppm, or 0.04%. 2.7 to 7.5% or 27,000 ppm to 75,000 ppm is between 67 and 187x the level of the atmosphere. Submarines can have CO2 levels near 10,000 ppm. The lungs have absolutely no problem handling high levels of CO2. Plants are the same. Higher CO2 levels make plants more drought resistant and greatly increases their yields. Plants die when CO2 drops below 180 ppm.

typical or physiological CO2 levels in the lungs which range from about 20 to 50 mm Hg or from about 2.7 to 7.5%.

It is for that reason, I questioned Chris Wallace’s approach and had to check out the American Lung Association. Sure enough, the American Lung Association makes the obligatory platitudes towards “climate change,” but never with an “N” mentions CO2 as a harmful pollutant. Sometimes a half-truth is often quite the lie. They did nothing to clarify the critical role CO2 plays in improving and saving the lives of every living organism. They do vaguely mention “carbon pollution” and state that utility plants produce CO2, but conveniently never mention CO2 as a health risk. Interestingly, they do mention that “biomass plants” are major sources of pollution. I’m pretty sure far more people die and suffer from natural causes of asthma and hayfever than CO2. I’ve never heard of anyone having an allergic or asthma reaction to CO2.  The very concept is laughable.
