Rapid response of Helheim Glacier in Greenland to climate variability over the past century
the largest ice-mass loss of the instrumental record 1, largely as a result of the acceleration, thinning and retreat of large outlet glaciers in West and southeast Greenland 2–5. The quasi-simultaneous change in the glaciers suggests a common climate forcing. Increasing air 6 and ocean 7,8 temperat...
