Global Sea Level Rise

How much the world's average sea level has risen each year since 1880.

Annual global mean sea level change compiled by the US Environmental Protection Agency from CSIRO reconstructions and NOAA satellite measurements, with error bounds. Climate-risk, insurance, property and ESG platforms use it for coastal risk context and reporting.
