In the most detailed picture to date, information from ESA's CryoSat satellite reveals how melting ice in Greenland has recently contributed twice as much to sea-level rise as the prior two decades. Between 2011 and 2014, Greenland lost around one trillion tonnes of ice. This corresponds to a 0.75 mm contribution to global sea-level rise each year – about twice the average of the preceding two decades. The study, published in Geophysical Research Letters today, combines data from the CryoSat mission with a regional climate model to map changes in Greenland ice-sheet mass. It is the most detailed recent picture of ice loss from Greenland. http://phys.org/news/2016-07-cryosat-reveals-greenland-ice-loss.html Study: http://onlinelibrary.wiley.com/doi/10.1002/2016GL069666/full
