Darryl CousinsThe results of the study that this article reports upon is that if atmospheric CO₂ levels continue to rise at the current rate then within several decades (50-odd years) our blood chemistry will be altered such that healthy homeostasis will be compromised.
So if you are concerned about water scarcity, sea level rise, damage due to floods and storms, crop failures, war, pestilence, and mass migrations here is something to add to the list of things driving us all toward a mass extinction event.
Stop fossil fuels. Stop war.

Rising carbon dioxide levels now detected in human blood
Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue. The findings are especially relevant for children and adolescents, whose developing bodies will experience the longest cumulative exposure to rising atmospheric CO₂.
