Projected sea surface temperature anomalies under different SSP scenarios for European seas and global ocean

CMIP6 models (32 for SSP1-2.6, 32 for SSP2-4.5 and 22 for SSP5-8.5) are spatially averaged in their native grid for each of the European seas and the global ocean. The anomaly is computed against the model's period 1991-2010, then the 30-year climatology for 2070-2100 of each model is included to construct the boxplots showing 5th, 25th, 50th, 75th and 95th percentiles.
SSP scenarios (Shared Socioeconomic Pathways) are the new scenarios representing different socio-economic developments as well as different pathways of atmospheric greenhouse gas concentrations. Five narratives describe different path of economy and society (SSP1-SSP5) from the sustainable and “green” pathway (SSP1) to fossil-fueled development and integration of global markets (SSP5). Individual scenarios are followed by two numerals indicating the additional radiative forcing achieved by the year 2100 in units of watts per square meter. For the sake of simplicity, only scenarios SSP1-2.6, SSP2-4.5 and SSP5-8.5 are used in Figure 2.

The areas used for the regional seas are the following:
• Europe: 35°-70°N, 25°W-40°E
• Baltic Sea: 52.5°-67.5°N, 8.5°-30.5°E
• Black Sea: 39.5°-48.5°N, 27.5°W-42.5°E
• Mediterranean: 30.5°-46.5°N, 6.5°W-38.5°E
• North Sea area 50.5°-60.5°N, 5.5°W-9.5°E
