Peak refreezing in the Greenland firn layer under future warming scenarios

Nature Communications, 2022
Greenland firn, the layer of compressed snow that today covers 90% of the ice sheet, currently retains half of the meltwater through refreezing. Here the authors use climate simulations to predict that refreezing in Greenland firn could peak at around ...

Greenland bare-ice albedo from PROMICE automatic weather station measurements and Sentinel-3 satellite observations

GEUS Bulletin, 2021
The Programme for Monitoring of the Greenland Ice Sheet (PROMICE) provides surface meteorological and glaciological measurements from widespread on-ice automatic weather stations since mid-2007.

Modelling snow accumulation on Greenland in Eemian, glacial inception, and modern climates in a GCM [PDF]

, 2012
Changing climate conditions on Greenland influence the snow accumulation rate and surface mass balance (SMB) on the ice sheet and, ultimately, its shape.

MIS-11 duration key to disappearance of the Greenland ice sheet [PDF]

, 2017
Palaeo data suggest that Greenland must have been largely ice free during Marine Isotope Stage 11 (MIS-11). However, regional summer insolation anomalies were modest during this time compared to MIS-5e, when the Greenland ice sheet likely lost less ...

Unprecedented atmospheric conditions (1948–2019) drive the 2019 exceptional melting season over the Greenland ice sheet

The Cryosphere, 2019
. Understanding the role of atmospheric circulation anomalies on the surface mass balance of the Greenland ice sheet (GrIS) is fundamental for improving estimates of its current and future contributions to sea level rise.

Update of annual calving front lines for 47 marine terminating outlet glaciers in Greenland (1999–2018)

Geological Survey of Denmark and Greenland Bulletin, 2019
The Greenland ice sheet has been losing mass in response to increased surface melting (Khan et al. 2015; van den Broeke et al. 2017) as well as discharge of ice from marine terminating outlet glaciers (van den Broeke et al. 2009; Box et al. 2018). Marine

Greenland Ice Sheet surface melt amplified by snowline migration and bare ice exposure

Science Advances, 2019
Greenland’s snowline exhibits large fluctuations and is a primary amplifier of ice sheet surface melt and runoff. Greenland Ice Sheet mass loss has recently increased because of enhanced surface melt and runoff.

The Greenland-Ice-Sheet evolution over the last 24 000 years: insights from model simulations evaluated against ice-extent markers [PDF]

The Cryosphere
Continental ice sheets retain a long-term memory stored in their geometry and thermal properties. In Greenland, this creates a disequilibrium with the present climate, as the ice sheet is still adjusting to past changes that occurred over millennial ...

Monitoring of the Greenland ice sheet using a broadband seismometer network: the GLISN project

Antarctic Record, 2014
Global climate change is currently causing melting of the Greenland ice sheet. Recently, a new type of seismic event, referred to as a "glacial earthquake", has been recognized.
