Ice sheets and sea level of the Last Glacial Maximum

This paper outlines the general issues regarding ice sheets and sea level of the Last Glacial Maximum (LGM), which formed the basis of an EPILOG Project workshop. Papers in this special issue of Quaternary Science Reviews provide a comprehensive assessment of these issues from the perspective of geological reconstructions of ice sheet extent, records of sea-level change, ice sheet modelling, ge...

How much are glaciers and ice sheets contributing to global sea-level rise?

From measurements made by the IPCC it is clear that Global sea level is rising, however the direct cause of this rise is not yet fully certain, although there is strong evidence that glacier melt is a strong causal factor. Global sea level rose by about 120 meters during the several millennia that followed the end of the last ice age (approximately 21,000 years ago), and stabilized between 3,00...

An expert judgement assessment of future sea level rise from the ice sheets

A major gap in predictive capability concerning the future evolution of the ice sheets was identified in the Fourth Assessment Report (AR4) of the Intergovernmental Panel on Climate Change. As a consequence, it has been suggested that the AR4 estimates of future sea-level rise from this source may have been underestimated. Various approaches for addressing this problem have been tried, includin...

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 sea level approximately 70 meters if completely melted, dominate uncertainties in projected sea-level change. Freshwater fluxes from these ice sheets also may affect oceanic circulation, contributing to cl...
