Greater Greenland Ice Sheet contribution to global sea level rise in CMIP6 [PDF]

Nature Communications, 2020
The potential contribution of Greenland Ice Sheet to sea level rise in the future is known to be substantial. Here, the authors undertake new modelling showing that the Greenland Ice Sheet sea level rise contribution is 7.9 cm more using the CMIP6 SSP585

Increased crevassing across accelerating Greenland Ice Sheet margins. [PDF]

Nat Geosci
Abstract Surface crevassing on the Greenland Ice Sheet is a large source of uncertainty in processes controlling mass loss due to a lack of comprehensive observations of their location and evolution through time. Here we use high-resolution digital elevation models to map the three-dimensional volume of crevasse fields across the Greenland ...

Clouds enhance Greenland ice sheet meltwater runoff [PDF]

Nature Communications, 2016
Clouds play a pivotal role in the energy and mass balance of the Greenland ice sheet, thereby affecting its contribution to global sea-level rise. Here, using a combination of observations and model simulations, the authors show that clouds enhance ...

Drill-site selection for cosmogenic-nuclide exposure dating of the bed of the Greenland Ice Sheet [PDF]

The Cryosphere, 2022
Direct observations of the size of the Greenland Ice Sheet during Quaternary interglaciations are sparse yet valuable for testing numerical models of ice-sheet history and sea level contribution. Recent measurements of cosmogenic nuclides in bedrock from

ICE FLOW VELOCITY MAPPING IN GREENLAND USING HISTORICAL IMAGES FROM 1960s TO 1980s: SCHEME DESIGN [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Ice flow velocity over long time series in Greenland plays a vital role in estimating and predicting the mass balance of the Greenland Ice Sheet and its contribution to global sea level rise.

Investigating the local-scale influence of sea ice on Greenland surface melt [PDF]

The Cryosphere, 2017
Rapid decline in Arctic sea ice cover in the 21st century may have wide-reaching effects on the Arctic climate system, including the Greenland ice sheet mass balance. Here, we investigate whether local changes in sea ice around the Greenland ice sheet

Possibility of Stabilizing the Greenland Ice Sheet

Earth's Future, 2021
Recent acceleration in the retreat of the Greenland ice sheet under a warming climate has caused unprecedented challenges and threats to coastal communities due to the rising sea level and increasing storm surges.

How warm was Greenland during the last interglacial period? [PDF]

Climate of the Past, 2016
The last interglacial period (LIG, ∼ 129–116 thousand years ago) provides the most recent case study of multimillennial polar warming above the preindustrial level and a response of the Greenland and Antarctic ice sheets to this warming, as well as a ...

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 ...

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
