Coupled regional climate–ice-sheet simulation shows limited Greenland ice loss during the Eemian [PDF]
Climate of the Past, 2013 During the last interglacial period (Eemian, 130–115 kyr BP) eustatic global sea level likely peaked at > 6 m above the present-day level, but estimates of the contribution of the Greenland Ice Sheet vary widely.

An ice sheet model validation framework for the Greenland ice sheet [PDF]
Geoscientific Model Development, 2016 Abstract. We propose a new ice sheet model validation framework – the Cryospheric Model Comparison Tool (CmCt) – that takes advantage of ice sheet altimetry and gravimetry observations collected over the past several decades and is applied here to modeling of the Greenland ice sheet.

Brief communication "The aerophotogrammetric map of Greenland ice masses" [PDF]
The Cryosphere, 2013 The PROMICE (Programme for Monitoring of the Greenland Ice Sheet) aerophotogrammetric map of Greenland ice masses is the first high resolution dataset documenting the mid-1980s areal extent of the Greenland Ice Sheet and all the local glaciers and ice ...

Exceptionally high heat flux needed to sustain the Northeast Greenland Ice Stream [PDF]
The Cryosphere, 2020 The Northeast Greenland Ice Stream (NEGIS) currently drains more than 10 % of the Greenland Ice Sheet area and has recently undergone significant dynamic changes.

Eemian Greenland ice sheet simulated with a higher-order model shows strong sensitivity to surface mass balance forcing [PDF]
The Cryosphere, 2019 The Greenland ice sheet contributes increasingly to global sea level rise. Its history during past warm intervals is a valuable reference for future sea level projections.

Design and results of the ice sheet model initialisation initMIP-Greenland: an ISMIP6 intercomparison [PDF]
The Cryosphere, 2018 Earlier large-scale Greenland ice sheet sea-level projections (e.g. those run during the ice2sea and SeaRISE initiatives) have shown that ice sheet initial conditions have a large effect on the projections and give rise to important uncertainties. The

Threatened loss of the Greenland ice-sheet [PDF]
Nature, 2004 The Greenland ice-sheet would melt faster in a warmer climate and is likely to be eliminated — except for residual glaciers in the mountains — if the annual average temperature in Greenland increases by more than about 3 °C. This could raise the global average sea-level by 7 metres over a period of 1,000 years or more.

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]
The Cryosphere, 2013 We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

Greenland ice sheet mass balance from 1840 through next week
Earth System Science Data, 2021 . The mass of the Greenland ice sheet is declining as mass gain from snowfall is exceeded by mass loss from surface meltwater runoff, marine-terminating glacier calving and submarine melting, and basal melting. Here we use the input/output (IO) method to

Holocene deceleration of the Greenland Ice Sheet [PDF]
Science, 2016 Keeping a stiff upper layer The interior of the Greenland Ice Sheet is growing thicker, in contrast to the thinning that is occurring at its edges. Why? MacGregor et al. conclude that more snow is accumulating and that the ice in the interior is flowing more slowly than it did thousands of years ago (see ...
