Warming temperatures contribute to sea level rise by: expanding ocean water; melting mountain glaciers and ice caps; and causing portions of the Greenland and Antarctic ice sheets to melt or flow into the ocean. [3]

Since 1870, global sea level has risen by about 7.5 inches. [2] Estimates of future sea level rise vary for different regions, but global sea level for the next century is expected to rise at a greater rate than during the past 50 years. [2] Studies project global sea level to rise by another 1 to 4 feet by 2100, with an uncertainty range of 0.66 to 6.6 feet.

New York State Department of Environmental Conservation (DEC) recently proposed science-based projections of sea-level rise for New York State’s tidal coast by region.  These proposed sea level projections are being established for use in future environmental assessments that include flood projections and the effects of sea level rise.

See below chart projections below.
