There is concern about sea level rise caused by ice loss (melt and glaciers falling into the sea) on Greenland. Between 1997 and 2003 ice loss was , compared to about  for 1993/4-1998/9. Half of the increase was from higher summer melting, with the rest caused by the movements of some glaciers exceeding the speeds needed to balance upstream snow accumulation. A complete loss of ice on Greenland would cause a sea level rise of as much as .
