Extended Data Fig. 5: Inter-model analysis using ETIN-MIP data.
From: Recent global climate feedback controlled by Southern Ocean cooling
Global-mean a, total climate feedback λtotal and b, net cloud feedback λcloud from the multi-model ETIN-MIP experiments with reduced insolation between 45°S–65°S, versus Southeast Pacific cloud feedback strength estimated from the pre-industrial control run CFSEP (that is, shortwave cloud radiative effect regressed onto local SSTs, with both variables de-trended and deseasonalized). c, Global-mean total climate feedback difference between the synthetic experiment 4xCO2-SO and 4xCO2, versus CFSEP. d, Comparison of Southeast Pacific cloud feedback metrics based on local temperature (CFSEP in the abscissa) versus global-mean temperature (4xCO2 shortwave cloud feedback in the ordinate, calculated as shortwave cloud radiative effect regressed onto global surface air temperature). The two metrics are closely related with a correlation coefficient of 0.78.
