A persistent and dynamic East Greenland Ice Sheet over the past 7.5 million years [PDF]
Nature, 2016 Climate models show that ice-sheet melt will dominate sea-level rise over the coming centuries, but our understanding of ice-sheet variations before the last interglacial 125,000 years ago remains fragmentary.

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.

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 ...

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.

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

Greenland Ice Sheet: Increased coastal thinning [PDF]
Geophysical Research Letters, 2004 Repeated laser‐altimeter surveys and modelled snowfall/summer melt show average ice loss from Greenland between 1997 and 2003 was 80 ± 12 km3 yr−1, compared to about 60 km3 yr−1 for 1993/4–1998/9. Half of the increase was from higher summer melting, with the rest caused by velocities of some glaciers exceeding those needed to balance upstream snow ...

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.

Constraining GRACE-derived cryosphere-attributed signal to irregularly shaped ice-covered areas [PDF]
The Cryosphere, 2013 We use a Monte Carlo approach to invert a spherical harmonic representation of cryosphere-attributed mass change in order to infer the most likely underlying mass changes within irregularly shaped ice-covered areas at nominal 26 km resolution.

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.
