Large-ensemble simulations of the North American and Greenland ice sheets at the Last Glacial Maximum with a coupled atmospheric general circulation–ice sheet model [PDF]

Climate of the Past
The Last Glacial Maximum (LGM) was characterised by huge ice sheets covering the Northern Hemisphere, especially over North America, and by its cold climate.

Changes in the Greenland Ice Sheet of the Southeastern Maniitsoq Coast from 1994-2004 and 2009-2019 [PDF]

, 2019
Remote sensing mechanisms through the use of technology like the Landsat 5-7 Land Manager satellites are commonly used in conjunction with multispectral methods such as unsupervised classification to record and analyze changes in snow and ice over time ...

Subglacial lake drainage detected beneath the Greenland ice sheet [PDF]

, 2015
The contribution of the Greenland ice sheet to sea-level rise has accelerated in recent decades. Subglacial lake drainage events can induce an ice sheet dynamic response—a process that has been observed in Antarctica, but not yet in Greenland, where the ...

Subglacial valleys preserved in the highlands of south and east Greenland record restricted ice extent during past warmer climates [PDF]

The Cryosphere
The Greenland Ice Sheet is a key contributor to contemporary global sea level rise, but its long-term history and response to episodes of warming in Earth's geological past remain uncertain.

Large and irreversible future decline of the Greenland ice sheet

The Cryosphere, 2020
. 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 (Glimmer) coupled to an atmosphere general circulation model ...

Greenland Ice Sheet Response to Stratospheric Aerosol Injection Geoengineering

Earth's Future, 2019
The Greenland ice sheet is expected lose at least 90% of its current volume if ice sheet summer temperatures warm by around 1.8 °C above pre‐industrial. Geoengineering by stratospheric sulfate aerosol injection might slow Greenland ice sheet melting and ...

Million years of Greenland Ice Sheet history recorded in ocean sediments [PDF]

, 2011
Geological records from Tertiary and Quaternary terrestrial and oceanic sections have documented the presence of ice caps and sea ice covers both in the Southern and the Northern hemispheres since Eocene times, approximately since 45 Ma.

Short-term impacts of enhanced Greenland freshwater fluxes in an eddy-permitting ocean model [PDF]

, 2010
In a sensitivity experiment, an eddy-permitting ocean general circulation model is forced with realistic freshwater fluxes from the Greenland Ice Sheet, averaged for the period 1991–2000.

Adding a dynamical cryosphere to iLOVECLIM (version 1.0): coupling with the GRISLI ice-sheet model [PDF]

Geoscientific Model Development, 2014
We present a coupling approach to and the first results of the GRISLI ice-sheet model within the iLOVECLIM-coupled climate model. The climate component is a relatively low-resolution earth system model of intermediate complexity, well ...

Holocene thinning in central Greenland controlled by the Northeast Greenland Ice Stream

Nature Communications
Ice-core records from the interior of the Greenland ice sheet suggest widespread thinning during the Holocene. However, the recurring underestimation of this thinning in numerical models raises concerns about both the veracity of such reconstructions and
