|Global Sea Level rise faster than expected|
Sea levels around the world are rising.
Between 1870 and 2004, global average sea levels rose 195 mm (7.7 inches), or almost 20 cm.
From 1950 to 2009, measurements show an average annual rise in sea level of about 1.7 mm per year, with satellite data showing a rise of about 3.3 mm per year from 1993 to 2009, a much faster rate of increase than previously estimated.
Two main factors contributed to observed sea level rise.
The second is from the contribution of land-based ice due to increased melting. The major store of water on land is found in glaciers and ice sheets.
