This is not what I needed to start my Saturday morning with

Given that the entire evolution period for humans has seen a stable and relatively low atmospheric CO2 level (< 300 ppm), it’s possible that our physiology is finely tuned for a range of CO2 that will not be much greater than this level. As the atmospheric CO2 levels rise, already at 420 ppm, the increasing levels of bicarbonate, and decreasing levels of calcium and phosphorus in our blood represent permanent and growing changes in human blood chemistry. These changes can be explained by CO2 retention and overload in the body. The extra CO2 being inhaled isn’t expelled via increased ventilation, as ventilation rate is controlled by pH which has likely remained stable due to acid-base regulation. CO2 storage in the body then becomes a major issue presenting a risk to population health and an existential threat for many species especially given that the rise in atmospheric CO2 may be a phenomenon that has significant momentum. Realistically, to mitigate this approaching threat, the alarm needs to be raised immediately. Unfortunately, currently there is little awareness or inclination for action on this issue.
