Greenland is no longer a terrain of pure and infinite glacial white. Melting during the summer season now reveals it to be a place increasingly marred with blue meltwater and grays and blacks from collected dust, ash and soot materials deposited from across the globe, also known as cryoconite. The local melt rate of ice has been measured to double when cryoconite is present, which is due to to the lowering of albedo/reflectivity of the ice. In 2014, meltwater from the Greenlandic ice sheet was responsible for 1.2mm gain in sea levels.
