Our biggest concern with atmospheric CO2 levels is as a greenhouse gas.
Our second-biggest concern with atmospheric CO2 levels is as an ocean acidifier.
A more distant but still important problem with higher atmospheric CO2 levels is that it raises the baseline for indoor CO2 buildup. With open-air levels >430ppm it takes less time for indoor levels to reach a generally uncomfortable 700ppm (or a sleep-inducing 1000ppm).
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.
“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.”

There may not be time to wait for more scientific certainty, Schulz said: “In 10 years, it might be too late to do anything about it.”
