The Decline of the Arctic

New research using combined records of ice measurements from NASA's Ice, Cloud and Land Elevation Satellite (ICESat), the European Space Agency's CryoSat-2 satellite, airborne surveys and ocean-based sensors shows Arctic sea ice volume has declined 36 percent in the autumn and nine percent in the winter over the last decade. The work builds on previous studies using submarine and NASA satellite data, confirms computer model estimates that showed ice volume decreases over the last decade, and builds a foundation for a multiple decade record of sea ice volume changes.
