ABSTRACT
Globally averaged sea level rose by about 15 cm over the course of the 20th century. Superimposed on this global rise are regional variations associated with vertical land movement. In some regions the land is rising so quickly that sea level is sinking with respect to the land (e.g., Fennoscandia). In other regions the land is sinking and this can result in local rates of sea level rise that greatly exceed the globally averaged value of 1.5 mm per year.
