sciencehabit (1205606) writes "Greenland's white snow is getting darker. Scientists have generally attributed that darkening to larger, slightly less white snow grains caused by warmer temperatures. But researchers have found a new source of darkening taking hold: impurities in the snow. The new darkening effect could easily add 2 centimeters to the projections of 20 cm sea level rise by 2100—and perhaps more if impurity levels grow with time."
