Let’s have a look at the Greenland Ice Sheet today. Ninety-five percent of the ice sheet is spectacularly white, except for one strip along the southwest coast. I fly over that section of Greenland on a regular basis, and the ice there is covered with very dark soot or dirt – which appears to have blown in from somewhere. The dirt absorbs sunlight and causes the melt, not the other way around.
