Animation - Greenland Ice Loss

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. These results from the UK Centre for Polar Observation and Modelling (CPOM) at the University of Leeds combine data from the CryoSat mission with a regional climate model to map changes in Greenland ice-sheet mass.

Arctic Ice freeboard (thickness)

Ice freeboard (in meters) estimates from Cryosat-2 in March 2011, 2012 and 2013. Freeboard is used as a proxy for ice thickness.

CryoSat

Artist’s impression of the CryoSat satellite in orbit.

The launch of the CryoSat spacecraft was unfortunately aborted on 8 October 2005 due to a malfunction of its Rockot launcher, which resulted in the total loss of the spacecraft.
