Here's one of the side effects of North Country fires... "dark snow" falling on white glaciers. <<*Slate* Exclusive: Why Greenland’s “Dark Snow” Should Worry You By Eric Holthaus Isn’t ice supposed to be white?Photo by Jason Box Jason Box knows ice. That’s why what’s happened this year concerns him so much. Box just returned from a trip to Greenland. Right now, the ice there is … black: Dark ice is helping Greenland’s glaciers retreat.Photo by Jason Box Crevasses criss-cross the Greenland ice sheet, allowing melt water to descend deep beneath the ice.Photo by Jason Box This year, Greenland’s ice was the darkest it’s ever been.Photo by Jason Box Box and his team are trying to discover what made this year’s melt season so unusual.Photo by Jason Box Box marks his study sites, appropriately, with black flags.Photo by Jason Box Box’s ‘Dark Snow’ project is the first scientific expedition to Greenland to be crowdfunded.Photo by Jason Box Advertisement The ice in Greenland this year isn’t just a little dark—it’s record-setting dark. Box says he’s never seen anything like it. I spoke to Box by phone earlier this month, just days after he returned from his summer field research campaign. “I was just stunned, really,” Box told me. The photos he took this summer in Greenland are frightening. But their implications are even more so. Just like black cars are hotter to the touch than white ones on sunny summer days, dark ice melts much more quickly. As a member of the Geological Survey of Denmark and Greenland, Box travels to Greenland from his home in Copenhagen to track down the source of the soot that’s speeding up the glaciers’ disappearance. He aptly calls his crowdfunded scientific survey Dark Snow. Message 29718702
