Table 1 Contribution of Greenland catchment basins to LSL.

GFM-derived contribution of five catchment basins (Petermann Glacier, Helheim Glacier, North-East Greenland Ice Stream, and Jakobshavn Glacier, all delimited in fig. S1) to LSL in 30 cities around the world based on an average of two SeaRISE model runs (see Materials and Methods) over a 200-year time period. For each basin, the projected GMSL value is provided for reference. For each city, a value of LSL is provided in cm, along with a ratio to GMSL in %.
