- Figs. 5 and 6: the total Arctic-sea ice area (SIA) and volume (SIV) decrease in all experiments with higher SST, in agreement with the OHT increase; the SIA decrease is larger with increased SST for the 2 first domains, but not for the BSO domain (where the strength of the SIA decrease is relatively similar between the 3 experiments);

- Fig. 8: the mixed layer depth in the Labrador, northern North Atlantic and Greenland-Iceland-Norway (GIN) Seas decreases with higher SST for the 2 larger domains (North Atlantic and northern North Atlantic); this probably explains the OHT decrease south of 60N, following a weakening of the overturning circulation;

- Fig. 9: the mean March sea-ice concentration clearly decreases in the Barents and GIN Seas in the North Atlantic and northern North Atlantic experiments (top and middle rows) and this decrease is much less pronounced in the case of the BSO experiment (bottom row); furthermore, increasing the SST in the North Atlantic experiment (top row, from left to right) clearly decreases the sea-ice concentration in the Barents and Kara Seas, with a farther spread of ocean heat.

**Fig. 1: Latitudinal transect of mean Atlantic OHT averaged over 50 years (except 2000-2014 for the CMIP6 r1 member to compare to TF2017); OHT estimates from Trenberth and Fasullo (TF2017) and hydrographic measurements (as in Grist et al., 2018) are plotted for reference; the number in brackets is the difference in mean OHT between the experiment and the control (CTRL)**
