The ice of “Ice Watch” indeed weighs in at a whopping 100 tons, having been collected by Royal Arctic Line divers and dockworkers near the Nuup Kangerlua fjord outside Nuuk, Greenland. The pieces were shipped in four refrigerated containers to Denmark before being left to melt in the middle of the central city square. As they crack, break and disappear, members of the public are able to witness firsthand the death of Arctic ice. Frank Jensen, Copenhagen’s mayor, and Rasmus Helveg Petersen, the Danish Minister for Climate, Energy and Building, stand behind the striking show.
