Extended Data Fig. 2: Response of the Southern Ocean warming to equilibrium climate sensitivity.
From: Future Southern Ocean warming linked to projected ENSO variability
a, Regression pattern of projected change in mean state of Southern Ocean temperatures to equilibrium climate sensitivity (ECS) from a previous study64. Stippling indicates where the correlation is statistically significant above the 90% confidence level based on a Student’s t-test. b, Inter-model relationship between ECS and the SO warming index, that is, a regional average in the upper 1000 m between 40°S and 60°S as indicated by the black box in Fig. 1b. c, Inter-model relationship between ECS and the projected changes in global mean surface temperature (GMT) which shows that they are highly correlated with each other. Therefore, the projected changes in global mean temperature are used in this study to represent ECS in each model to include as many models as possible. The correlation coefficient, slope, and p-value are indicated. The purple ellipse indicates 5–95% ranges.
