This is a several-years old study that has been controversial. Other results using independent observations from mass-observing missions have come to very different conclusions [1] [2]. One thing people should understand is that the method used in the linked article is altimetry from radar, so you get a very accurate surface height, but the height is not a direct indicator of ice mass because of compression of snow/ice, and rebound of the underlying continent. It's really important to have some appreciation of the limitations of measurement techniques, before jumping to conclusions from a single study.
