Slate is featuring the Dark Snow Project. Photos taken this past summer by Jason Box document just how impressively dark the ice sheet surface has become in South Greenland.

The Slate piece describes how 2014 was not only the darkest ice sheet summer on record, it was also the most intense forest fire summer on record. The darker the ice sheet becomes, the more solar radiation it absorbs, and the faster in melts. A link between forest fires and ice sheet melt would be a rather unexpected climate feedback!
