Is the rate of sea-level rise increasing?
Yes. Relying on nearly a 30-year record of satellite measurements, scientists have measured the rate of sea-level rise at 0.13 inches (3.4 millimeters) per year. And during this satellite period, 1993 to present, emerging indications suggest the mean (average) rate of global mean sea-level rise has increased – from about 0.1 inches (2.5 millimeters) to 0.13 inches (3.4 millimeters). Further measurements in coming years, by the Sentinel-6/Michael Freilich satellite, the Surface Water and Ocean Topography (SWOT) satellite, and others, will help establish the rate of increase more precisely.
