These sea level rise risk projection products capture projected risk of decadally-averaged sea level rise exceeding the altitude of the local bathymetry for all locations globally. These risk maps reflect the future long-term risk from sea level rise globally at decadal time steps for an intermediate emissions scenario.
These maps compare sea level rise projections developed by NOAA to a high-resolution global bathymetry map from the General Bathymetric Chart of the Oceans (GEBCO). The spatial scale for this dataset is roughly 1.8 km/pixel and data are available for the years 2020 - 2150.
The probability (between 0-1) that decadally-averaged sea level rise exceeds local bathymetry at each grid point is provided for the combinations of NOAA sea level rise scenario and time horizon.
