Since 1880, global mean sea level has risen by 8-9 inches (21-24 centimeters) .

Dataset

The National Aeronautics and Space Administration (NASA), in collaboration with The National Oceanic and Atmospheric Administration (NOAA), has developed several satellites to measure global sea levels, including TOPEX/Poseidon and the Jason satellite series: Jason-1, Jason-2, and Jason-3. These satellites have monitored the same areas since 1992, and the data from NOAA’s Laboratory for Satellite Altimetry provide insight into historical trends of sea level rise. In this dataset, the difference in mean sea level from each satellite is provided from 1992 to 2022.
