Sea-level changes at the LGM from ice-dynamic reconstructions of the Greenland and Antarctic ice sheets during the glacial cycles
Abstract New experiments were performed with three-dimensional thermomechanical models of the Greenland and Antarctic ice sheets to simulate their behaviour during the glacial cycles, to reconstructExpand

Calibrating a glaciological model of the Greenland ice sheet from the Last Glacial Maximum to present-day using field observations of relative sea level and ice extent
We constrain a three-dimensional thermomechanical model of Greenland ice sheet (GrIS) evolution from the Last Glacial Maximum (LGM, 21 ka BP) to the present-day using, primarily, observations ofExpand

Ice-Sheet and Sea-Level Changes
Future sea-level rise is an important issue related to the continuing buildup of atmospheric greenhouse gas concentrations. The Greenland and Antarctic ice sheets, with the potential to raise seaExpand

Elimination of the Greenland ice sheet in a high-CO2 climate
Projections of future global sea level depend on reliable estimates of changes in the size of polar ice sheets. Calculating this directly from global general circulation models (GCMs) is unreliableExpand

Ice-sheet contributions to future sea-level change
Accurate simulation of ice-sheet surface mass balance requires higher spatial resolution than is afforded by typical atmosphere–ocean general circulation models (AOGCMs), owing, in particular, to theExpand

The influence of North Atlantic atmospheric and oceanic forcing effects on 1900–2010 Greenland summer climate and ice melt/runoff
Correlation analysis of Greenland coastal weather station temperatures against the North Atlantic Oscillation (NAO) and the Atlantic Multidecadal Oscillation (AMO) indices for the summer season (whenExpand

Evolution of supra-glacial lakes across the Greenland Ice Sheet
Abstract We used 268 cloud-free Moderate-resolution Imaging Spectroradiometer (MODIS) images from 2003 and 2005–2007 to study the seasonal evolution of supra-glacial lakes in three different regionsExpand

Greenland Ice Sheet: Increased coastal thinning
[1] 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 forExpand

Runoff and mass balance of the Greenland ice sheet: 1958–2003
Meteorological models were used to retrieve annual accumulation, runoff, and surface mass balance on a 5 km A� 5 km grid for the Greenland ice sheet for 1958-2003. We present the first such historyExpand

Eight glacial cycles from an Antarctic ice core
The Antarctic Vostok ice core provided compelling evidence of the nature of climate, and of climate feedbacks, over the past 420,000 years. Marine records suggest that the amplitude of climateExpand
