In order to use tidal gauges to reliably
estimate global sea level changes, researchers have to successfully separate the components of shifting land heights and local sea level variability from any global trends.
Thirteen years of GRACE data provide an excellent picture of the current mass changes of Greenland and Antarctica, with mass loss in the GRACE period 2002 - 15 amounting to 265 ± 25 GT / yr for Greenland (including peripheral ice caps), and 95 ± 50 GT / year for Antarctica, corresponding to 0.72 mm / year and 0.26 mm / year
average global sea level change.

East Antarctica's Role in
Global Sea Level Change «will not result in any increase in sea level» — April 23, 2008
In view of the multiple modes and periods of internal variability in the ocean, it is likely that we have not detected the full scale of internal variability effects on regional and
global sea level change.
Global sea level changes are thought to be caused by geotectonic and glacial phenomena.
Over 500 million years back to the Cambrian Period we see
global sea level changes.
Sequence stratigraphy is based on
these global sea level changes.
