This timelapse depicts the changes in Greenland’s ice mass as detected by NASA’s GRACE satellite system. Between 2004 and 2014, an estimated 2,500 gigatons of ice had been lost from the Greenland landmass.
GRACE consists of two co-orbiting satellites that precisely measure the distance between the two spacecraft in order to make detailed measurements of the Earth’s gravitational field. Since launching in 2002, GRACE has provided a continuous record of changes in the mass of Earth’s ice sheets.
