SUMMARY:The contribution of melt ponds to enhanced Arctic sea-ice melt dur
 ing the Last Interglacial - Rachel Diamond\, British Antarctic Survey

DESCRIPTION:The Hadley Centre Global Environment Model version 3 (HadGEM3)
  is the first coupled climate model to simulate an ice-free Arctic during 
 the Last Interglacial (LIG)\, 127 000 years ago\, and appears to yield acc
 urate Arctic surface temperatures during the summer season. Here\, we inve
 stigate the causes and impacts of this extreme simulated ice loss. We find
  that the summer ice melt was predominantly driven by thermodynamic proces
 ses\, and significantly impacted by melt pond formation. Our results sugge
 st that models with more detailed melt pond schemes can simulate very diff
 erent sea ice behaviour under forcings other than the present day. This is
  of concern for future projections of sea-ice loss.
