Modern technology in the shape of the two GRACE (Gravity Recovery and Climate Experiment) satelites has enabled scientists in France to assess the rate at which sea levels are rising and what is responsible. For most of the last century, sea levels rose by 1.8mm, however since 1993 sea levels have been rising by 3.3 mm per year.
Anny Cazenave of LEGOS , Toulouse, says between 1993 and 2003, 50% of the sea level rise was due to thermal expansion and 50% due to land ice melting (glaciers, ice sheets).
Now about 80% is due to Greenland and Antarctic land ice melting whilst thermal expansion was a smaller contributing factor.
