NOAA: By 2050, U.S. Coastline Sea Level Expected to Rise 10-12 Inches

Sea levels along the United States coastline are expected to rise dramatically by the year 2050, according to a newly published report by NOAA, in cooperation with six other federal agencies.

The U.S. is expected to experience as much sea level rise by the year 2050 as it has experienced in the previous 100  years, the report says.

The Sea Level Rise Technical Report provides the most up-to-date sea level rise projections for all U.S. states and territories by decade for the next 100 years and beyond, based on a combination of tide gauge and satellite observations and all the model ensembles from the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC). The report projects sea levels along the coastline will rise an additional 10-12 inches by 2050 with specific amounts varying regionally, mainly due to land height changes.

The report updates the federal government’s 2017 sea level rise projections, and provides additional information on tide, wind, and storm-driven extreme water levels affecting current and future coastal flood risk. A suite of federal tools are using this data, including the NOAA Sea Level Rise Viewer.
