The GRACE
observations over Antarctica suggest a near - zero change due to
combined ice

models have suggested
and hence we produce a systematically lower estimate of ice mass change from GRACE data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged sea level change, or about 6 % of the sea - level change during that period.
