The pattern of changes in Sea Surface Temperatures (SSTs) over recent decades has been marked by enhanced warming in the western equatorial Pacific and cooling in the eastern Pacific and Southern Ocean. Current state-of-the-art coupled Atmosphere- Ocean General Circulation Models (AOGCMs) fail to reproduce this observed pattern. Here we compare the coupled CESM1 and CMIP6 initial-condition large ensembles against Atmosphere- only GCMs forced with observed SSTs and sea-ice concentrations from the Atmospheric Model Intercomparison Project (AMIP) and against reanalysis.
