Mediterranean Sea level is projected to rise further during the coming decades and centuries , likely reaching 0.15-0.33 m in 2050, and 0.3-0.6 m for shared socioeconomic pathways  1-1.9 and 0.6-1.1 m for SSP5-8.5 in 2100  . Higher values cannot be excluded  and the process is irreversible at the scale of centuries to millennia . Coastal flood risks will increase in low-lying areas along 37% of the Mediterranean coastline that currently hosts 42 million people. The number of people exposed to sea level rise is projected to increase up to 2050, especially in the southern and eastern Mediterranean region, and may reach up to 130% compared to present in 2100 . Coastal settlements, World Heritage sites and ecosystems are at longer-term risk from sustained sea level rise over at least the coming three centuries .
