Regressed seasonal cycles of the zonal mean of partial surface temperature changes (K) due to individual processes against PC1_N shown in Fig. 4b (for the Arctic warming) and PC1_S in Fig. 4d (for the Antarctic warming). Partial temperature changes due to feedbacks of (a) albedo, (b) atmospheric water vapor, (c) shortwave effect of clouds, (d) longwave effects of clouds, (e) the concentration of CO2, (f) atmospheric heat transport, (g) oceanic circulation and ocean heat storage term, and (h) surface turbulence sensible and latent heat fluxes. Black dots indicate the 95% confidence level of statistical significance.
