Data from NASA's GRACE satellites show that the land ice sheets in both Antarctica (left chart) and Greenland (right) have been losing mass since 2002. Both ice sheets have seen an acceleration of ice mass loss since 2009. (Source: GRACE satellite data)
Please note that the most recent data are from June 2017, when the GRACE mission concluded science operations. New data from GRACE’s successor mission, GRACE Follow-On, will be displayed when it becomes available.
