Phase Transition of CO2‐Driven Equatorial Pacific Warming Pattern Governed by Ocean Dynamics and Remote Forcing
Climate models robustly project an El Niño–like warming under rising CO2, yet recent observations show the opposite with enhanced zonal SST gradients. Whether the long‐term projection is relevant for interpreting historical trends remains questionable. Using a large‐ensemble of abrupt 4xCO2 experiment, we identify a tw...
