The Greenland Ice Sheet has been a major contributor to global sea-level rise in recent decades 1 , 2 , and it is expected to continue to be so 3 . Although increases in glacier flow 4 – 6 and surface melting 7 – 9 have been driven by oceanic 10 – 12 and atmospheric 13 , 14 warming, the magnitude and trajectory of the ice sheet’s mass imbalance remain uncertain. Here we compare and combine 26 individual satellite measurements of changes in the ice sheet’s volume, flow and gravitational… Expand

Forty-six years of Greenland Ice Sheet mass balance from 1972 to 2018
TLDR
Even in years of high SMB, enhanced glacier discharge has remained sufficiently high above equilibrium to maintain an annual mass loss every year since 1998, and the acceleration in mass loss switched from positive in 2000–2010 to negative in 2010–2018, which illustrates the difficulty of extrapolating short records into longer-term trends.

Variations of Mass Balance of the Greenland Ice Sheet from 2002 to 2019
TLDR
The mass balance of the Greenland Ice Sheet during the study period was at a loss, and this was closely related to increasing trends in temperature and precipitation, and the rate of mass change has accelerated significantly, mainly because of climate change. Expand
Dynamic response of the Greenland ice sheet to recent cooling
TLDR
It is hypothesized that under thinner ice, increases in basal water pressure offset a larger proportion of the ice overburden pressure, leading to reduced effective pressure and thus greater acceleration when compared to thicker ice further inland, and is strongly correlated with ice thickness.

Large and irreversible future decline of the Greenland ice sheet
Abstract. We have studied the evolution of the Greenland ice-sheet under a range of constant climates typical of those projected for the end of the present century, using a dynamical ice-sheet model… Expand

Centennial response of Greenland’s three largest outlet glaciers
TLDR
Historical photographs are used to calculate ice loss from 1880–2012 for Jakobshavn, Helheim, and Kangerlussuaq glacier to infer that projections forced by RCP8.5 underestimate glacier mass loss which could exceed this worst-case scenario. Expand
21 st century response of Petermann Glacier , northwest 1 Greenland to ice shelf loss 2
Ice shelves restrain flow from the Greenland and Antarctic ice 10 sheets. Climate-ocean warming could force thinning or collapse of floating 11 ice shelves and subsequently accelerate flow, increase… Expand
Global environmental consequences of twenty-first-century ice-sheet melt
TLDR
Increased meltwater from the Greenland and Antarctic ice sheets will slow the Atlantic overturning circulation and warm the subsurface ocean around Antarctica, further increasing Antarctic ice loss. Expand
Mass Balance of 14 Icelandic Glaciers, 1945–2017: Spatial Variations and Links With Climate
To date, most mass balance studies in Iceland have concentrated on the three largest ice caps. This study turns the focus toward smaller Icelandic glaciers, presenting geodetic mass-balance estimates… Expand
Greenland Ice Sheet Contribution to 21st Century Sea Level Rise as Simulated by the Coupled CESM2.1‐CISM2.1
The Greenland Ice Sheet (GrIS) mass balance is examined with an Earth system/ice sheet model that interactively couples the GrIS to the broader Earth system. The simulation runs from 1850 to 2100,… Expand
