###########Terms and units

Sea Surface Temperatures (SSTs) are in degrees Celsius. Latitude are in degrees north. Longitude in degrees east.

NZESM (New Zealand Earth system model; Williams et al., 2016), UKESM (United Kingdom Earth System model; Sellar et al., 2019),  HadISST 1870-1879 AD (HadleyCentre Sea Ice and Sea Surface Temperature; NCAR, 2022), mPWP (mid-Pliocene Warm Period 3.3 - 3.0 Ma), MIS5e (Marine Isotope Stage 5e; 125 ka). SSP1 /2/ 3 (Socio-economic Pathways; IPCC). UK'37 - alkenone biomarker SST proxy TEX - TEX86 biomarker SST proxy

Two periods were extracted from NZESM and UKESM i) 2036-2040 AD for SSP 2, and ii) 2090-2099 AD for SSP1, SSP 2, SSP 3. These are provided as stand alone values and in reference to HadiIST (e.g. NZESM - HadISST or NZESM.HadISST) 

Table 2. Statistical distribution of mid-Pliocene Warm Period (3.3-3.0 Ma) Sea Surface Temperatures anomalies (SST; °C) relative to HadiSST (1870-1879 AD) using BAYSPLINE calibration (Tierney and Tingley, 2018).  The total range is calculated as the difference between maximum and minimum temperature and represents glacial to interglacial extremes.

Table 3. Site annual mean Sea Surface Temperature anomalies (SST; °C) for UKESM and NZESM with respect to HadISST (1870-1879 AD) for SSP2-4.5 2040 AD (2036–2045 AD).  

Table 4. Site annual mean Sea Surface Temperature anomalies (SST; °C)for UKESM and NZESM with respect to HadISST (1870-1879 AD) for SSP1-2.6, SSP2-4.5, SSP3-7.0 at 2095 AD (2090–2099 AD).  

Table A1. Comparison between  derived SST using BAYSPLINE with TEX₈₆ -index SST calibrations of Schouten et al. (2002), Kim et al, (2010), OPTIMAL (Dunkley Jones et al., 2020) and BAYSPAR (Tierney and Tingley, 2015).

Table S1. All site sea surface temperature (SST; °C) data used in results with  index and calibrations of Müller98 (Müller et al., 1998) and BAYSPLINE (Tierney and Tingley, 2018). The proxy type and references are also provided.

Table S2. Site sample data for analyses undertaken this study, including all  and TEX₈₆ index calculations and calibrations. References for calibrations are contained within column headers.

Table S3. Seasonal and annual mean sea surface temperature (SST; °C) model outputs of HadISST (NCAR, 2022), UKESM (Sellar et al., 2019), NZESM (Williams et al., 2016) at the seven Southwest Pacific sites (DSDP 594, ODP 1172, ODP 1168, ODP 1125, ODP 1123, DSDP 593, DSDP 590) for SSP2 2040 AD (2036-2045 AD), and SSP1, 2, and 3 2095 AD (2090-2099 AD). Including UKESM and NZESM with respect to HadISST.

Table S4. Site sea surface temperature (SST; °C) annual means and seasonal range for UKESM and NZESM SSP2-4.5 2036-2045 AD, with MPWP interglacial modal means and total glacial range (maximum to minimum SST).  

Table S5. Compiled sea surface temperature (SST; °C) interglacial means for MIS 5e (125kyr; Cortese et al., 2013) and mPWP (3.3-3.0 Ma) and model annual means for HadISST (1870-1879 AD), and SSP2-4.5 2090-2099 AD for UKESM, NZESM.
