Inter-model regression of a grid-point rainfall variability change (1960–2030 minus piControl, mm d−1 per °C of global warming), b grid-point zonal wind stress (TAUU) variability change (1960–2030 minus piControl, N m−2 per °C of global warming) and c relative sea surface temperature (SST) warming (1960–2030 minus piControl, °C per °C of global warming) onto strength of ENSO non-linearity (measured by amplitude of Alpha over the whole period; see Methods). Black stippling in a–c indicates statistical significance above the 90% confidence level based on a two-tailed Student’s t-test. Results shown here are based on the RCP85/SSP585 scenario for a future warming climate.
