Sensitivity of Greenland ice sheet projections to model formulations
Physically based projections of the Greenland ice sheet contribution to future sea-level change are subject to uncertainties of the atmospheric and oceanic climatic forcing and to the formulations within the ice flow model itself. Here a higher-order, three-dimensional thermomechanical ice flow model is used, initialized to the present-day geometry. The forcing comes from a high-resolution regi...
متن کاملIce-dynamic projections of the Greenland ice sheet in response to atmospheric and oceanic warming
Continuing global warming will have a strong impact on the Greenland ice sheet in the coming centuries. During the last decade (2000–2010), both increased melt-water runoff and enhanced ice discharge from calving glaciers have contributed 0.6±0.1 mm yr to global sea-level rise, with a relative contribution of 60 and 40 % respectively. Here we use a higher-order ice flow model, spun up to presen...

متن کاملDark ice dynamics of the south-west Greenland Ice Sheet
Runoff from the Greenland Ice Sheet (GrIS) has increased in recent years due largely to changes in atmospheric circulation and atmospheric warming. Albedo reductions resulting from these changes have amplified surface melting. Some of the largest declines in GrIS albedo have occurred in the ablation zone of the south-west sector and are associated with the development of “dark” ice surfaces. Fi...
متن کاملDependence of century-scale projections of the Greenland ice sheet on its thermal regime
Observations show that the Greenland ice sheet has been losing mass at an increasing rate over the past few decades, which makes it a major contributor to sea-level rise. Here we use a threedimensional higher-order ice-flow model, adaptive mesh refinement and inverse methods to accurately reproduce the present-day ice flow of the Greenland ice sheet. We investigate the effect of the ice thermal...
