Relationship between GMST and HU/SWR in inter-annual variations for different areas. (a–d) Lagged regression (a,b) of net shortwave radiation (SWR) and of net heat uptake HU (c,d), against GMST. (a,b) SWR split between tropics (30°S and 30°N) and extra-tropics, ocean and land, and upward and downward shortwave radiation such that the black and purple lines in both panels sum to the green line in Fig. 1; HU split between tropics and extra-tropics such that both panels sum to Fig. 1. (c,d) Regression values are in W m⁻² K⁻¹.
