NASA reported that during the time period from 2002 to 2016, the continent of Antarctica lost 125 gigatons of ice as measured by the GRACE satellite instrument. The sea level rise from this ice loss amounts to 0.35 millimeters per year according to their report.  While this might not seem like much, ice loss is expected to accelerate as the earth gets warmer, and of course other sources of ice like glaciers and Greenland are also losing ice mass.
