Distribution of modelled interannual May–June SST anomalies with respect to 1850-1900 climatological mean for GWL = 0 °C (blue) and GWL = 1.3 °C (orange) for (a) NATL and (b) HS regions. Vertical thin bars correspond to multi-model multi-ensemble means for each GWL. The thick vertical bars (red) correspond to the 2023 anomalies from OSTIA (dashed) and ERSSTv5 (solid). Maps of the May-June relative SST anomaly (grid-point anomaly minus basin-wide averaged anomaly) for (c) ERSSTv5 in 2023 relative to 1991–2020 and for (d) CMIP6 anthropogenically forced response at GWL = 1.3 °C relative to 1850–1900. The blue contour stands for the HS mask.
