Although glaciers calving into the ocean cause much of the ice loss in Greenland, other research cited in the study shows that the majority of ice loss in recent years is from increased surface melt and runoff. (sciencedaily.com)
That's because the IPCC models only take into account temperature changes at the surface of glaciers, but not the rapid melting that occurs when glaciers calve and break up into the ocean, Rignot said. (scientificamerican.com)
Can a rising sea level can act as a boost for glaciers calving into the sea and trigger a surge of ice into the oceans? (realclimate.org)
