NASA study reveals the amazing geologic past of Greenland

Researchers say that if the Greenland ice sheet melting continues at ’unprecedented rates’ - which they attribute to warmer summers - it could accelerate the already fast pace of sea level rise. Ice loss from Greenland is one of the key drivers of global sea level rise, according to the study. Icebergs calving into the ocean from the edge of glaciers represent one component of water re-entering the ocean and raising sea levels. Original Article:
