Greenland ice change, 2015

The image shows Greenland ice-sheet annual elevation change in 2015, but using a 25-year record of ESA satellite data, recent research shows that the pace at which Greenland is losing ice is getting faster. The research, published in Earth and Planetary Science Letters, uses radar altimetry data gathered by the ERS, Envisat and CryoSat missions between 1992 and 2016.
