Extended Data Fig. 3: Estimation of the model drift.

Timeseries from our control simulation (constant climate and atmospheric CO₂ concentration) for A ocean CO₂ uptake [TgC yr⁻¹], B partial pressure of CO₂ in the surface ocean [μatm yr⁻¹], C Revelle factor [yr⁻¹], D export flux at 100 m [TgC yr⁻¹], and C DIC_REMIN [PgC yr⁻¹]. The model drift is extremely small compare to climate change and evidence a quasi-equilibrium for surface (CO₂ flux, \({p}_{\rm{CO}_2}\) and Revelle factor), intermediate (export flux at 100 m) and deep ocean variables (DIC_REMIN).
