By the middle of the 21st century, the annual flooded area of small island developing states due to sea level rise is expected to surpass 15 km², which represents an increase of 167 percent compared to 2020 levels. Following the worst case scenario (SSP5-8.5), almost 45 km² of small island nations' land is projected to be flooded by 2150.

Supplementary notes
Shared Socioeconomic Pathways (SSP):
SSP1-1.9: very low GHG emissions - CO₂ emissions cut to net zero around 2050.
SSP1-2.6: low GHG emissions - CO₂ emissions cut to net zero around 2075.
SSP2-4.5: intermediate GHG emissions - CO₂ emissions around current levels until 2050, then falling but not reaching net zero by 2100:
SSP3-7.0: high GHG emissions - CO₂ emissions double by 2100.
SSP5-8.5: very high GHG emissions - CO₂ emissions triple by 2075.
