AB: Present-day sea-level and geoid changes around Greenland are largely the result of mass fluctuations in the Greenland Ice Sheet (GIS). However, there is still a very strong effect arising from the on-going glacial-isostatic adjustment of the Earth due to the demise of the other late-Pleistocene ice sheets, especially those that covered North America. The GIS's contribution may be divided between that which arises from the ice-sheet retreat following Last Glacial Maximum (21 ka BP), and those changes that are occurring today. Predictions of sea-level change have been made and are compared with values inferred from tide-gauge time series. Similarly, predictions of geoid change that may be detectable by the GRACE gravity space mission are discussed, and compared with currently available data.
