Extended Data Fig. 4: Annual mean FCO₂ and SST anomalies in 2023 relative to a linear trend baseline.

Anomaly estimates from Table 1 are displayed as bars (fCO₂ product ensemble mean) with uncertainty ranges (standard deviation across four fCO₂ products). In addition to the results in Table 1, estimates for the individual fCO₂ products and GOBMs are displayed as symbols.
