Extended Data Fig. 3: Correlation between historically observed and modelled variability and extremes.
From: Multi-month forecasts of marine heatwaves and ocean acidification extremes

Correlation coefficient between historical (column 1) variability of (a) sea surface temperature, (c) Ωa, (e) [H+] and (column 2) extremes (b) marine heatwaves, (d) ocean acidification extremes (Ωa),(f) ocean acidification extremes ([H+]) in SMYLE FOSI and observations (OceanSODA-ETHZ). Higher correlation coefficients indicate more similar historical variability or extreme events.
