For at least the last 100 years, sea level has been rising at an average rate of about 1.8 mm (0.1 in) per year. Most of this rise can be attributed to the increase in temperature of the sea and the resulting slight thermal expansion of the upper 500 metres (1,640 feet) of sea water.recise determination of a mean sea level is a difficult problem because of the many factors that affect sea level. Sea level varies quite a lot on several scales of time and distance.
