Sea level rise is an increase in sea level. Multiple complex factors may influence such changes. The sea level has risen more than 120 m since the peak of the last ice age about 18000 years ago. However, only 2-4 m of this increase has occurred in the last 6000 years. From 3000 years ago to the 19th century the long term change was roughly 0.5 meters at a rate of 0.1 to 0.2 mm/yr. Modest 100 to 1000 year fluctuations may have been superimposed on this but are unlikely to have exceeded 0.3 to 0.5 m in amplitude [1]. Since 1850, sea level has risen again at 1 to 2 mm/yr [2] and since 1992 satellite altimetry from TOPEX/Poseidon suggests a rate of about 3 mm/yr [3]. These increased rates may indicate accelerating sea level change as a result of global warming. During the twenty-first century, global warming models predict a sea level rise of ~0.5 meters. en.wikipedia.org
