And here’s the rub:

The authors admit they don’t know whether the increase in old carbon emissions is from natural variability or anthropogenic disturbance. In their own words:

“Whether or not anthropogenic perturbation has increased the leak of old carbon…remains a notable knowledge gap”.

Yet we’re told with absolute certainty that the Earth will warm by 1.5°C unless we ban gas stoves, eat bugs, and shut down reliable energy. This study exposes just how deeply uncertain and unresolved the feedbacks in the carbon cycle remain.
