Seasonal sea level compared to the 1993-2008 average, based on a combination of tide gauges (light blue) and satellite data (darker blue). In 2020, global mean sea level hit a new record high: 91.3 mm (3.6 inches) above 1993 levels. Data from UHSLC.
Since the start of the satellite record in 1993, the height of the sea surface has risen virtually everywhere (blue). The rate of increase on shore (dots) may be accelerated or slowed by geological processes like erosion or glacial rebound. Data from UHSLC.
