Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 8 inches per century (2 mm/year).
Changes in sea level since the end of the last glacial episodeSea level rise is an increase in sea level. Multiple complex factors may influence such changes.

Sea level has risen around 130 metres (400 feet) since the peak of the last ice age about 18,000 years ago. Most of the rise occurred before 6,000 years ago. From 3,000 years ago to the start of the 19th century sea level was almost constant, rising at 0.1 to 0.2 mm/yr.[1] Since 1900 the level has risen at 1 to 2 mm/yr; since 1992 satellite altimetry from TOPEX/Poseidon indicates a rate of rise about 3 mm/yr.[2] The IPCC notes, however, “No significant acceleration in the rate of sea level rise during the 20th century has been detected.”[2]
