Carbon dioxide overload, detected in human blood, suggests a potentially toxic atmosphere within 50 years - Air Quality, Atmosphere & Health

Anthropogenic activities are increasing the amount of carbon dioxide (CO2) in the atmosphere. There is mounting experimental evidence that lifetime exposur

Closing thoughts of meticulous writeup:
"...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."
