Global gross primary productivity and biomass have undergone substantial changes throughout Earth history, driven by climate variations, atmospheric changes, and nutrient cycles.

The analysis

The claim states that global gross primary productivity and biomass have changed substantially over Earth history. Retrieved papers such as [0] and [9] model and quantify the spatial and temporal variations of global gross primary productivity (GPP) and carbon dynamics. Because these studies confirm significant fluctuations and drivers of terrestrial productivity on global scales, the claim is supported.
