The satelite data is not able to distinguish between sea level changes and changes in land elevation due to tectonic activity or erosion. El Nino and shifting water temperatures (and densities) are additional complications in proving a clear answer on sea levels.
It has been estimated that another 25 years of data collection will be required to make a distinction between these factors.

Who estimated that?
