Increased ENSO Sea Surface Temperature Variability under Four IPCC Emission Scenarios

ENSO Sea Surface Temperature (SST) variability underpins ENSO-related climate variability and climate extremes within and outside the Pacific. The recent IPCC sixth assessment reports no systematic change in ENSO SST variability under any emission scenarios considered. This study used the most recent CMIP6 models to compare 20th and 21st century SST variability, and found there is a robust increase in century-long ENSO SST variability under four IPCC plausible emission scenarios.
