Mean Sea Level Trends for Tropical Stations

The graph compares the 95% confidence intervals of the mean sea level trends. Trends with the narrowest confidence intervals are based on the longest data sets. Trends with the widest confidence intervals are based on only 25-30 years of data. The graph gives an indication of the differing rates of vertical land motion, given that the absolute global sea level rise is believed to be between 1.0 and 2.4 millimeters/year.
