"Some locations along the west coast of Greenland have warmed really strongly by about 2–4°C in summer and as much as 10°C locally in winter – in their average surface air temperatures since 1991," Edward Hanna of the University of Sheffield, UK, told environmentalresearchweb. "In general, warming has been much stronger in west Greenland than in the east. Similar warming trends are seen on the western flank of the ice sheet – at 1200 metres above sea level – as on the west coast, which indicates a significant impact of this strong warming on enhancing ice-sheet melt and mass loss."
