Data from NASA's GRACE and GRACE Follow-On satellites show that the land ice sheets in both Antarctica (left chart) and Greenland (right chart) have been losing mass since 2002.

The GRACE mission ended in June 2017. The GRACE Follow-On mission began collecting data in June 2018 and is continuing to monitor both ice sheets. This record includes new data-processing methods and is continually updated as more numbers come in, with a delay of up to two months.
