Seasonal vegetative cycles cause oscillations in the Keeling curve
the verdict
SUPPORTED
the evidence backs this
confidence 85/100
Seasonal variations in plant growth and decay drive regular uptake and release of carbon dioxide, which produce the characteristic annual oscillations observed in the Keeling curve.
