Even if the global community were to double down in its efforts to protect the climate, it would not be able to give the Arctic Ocean back its ice. But, in a symbolic act, Hamburg-based conceptual artist Swaantje Güntzel has done just that: on 18 November, at Båtsfjord in the far north of Norway, she produced ice cubes from meltwater taken from the North Pole and let them slip into the sea. This artistic intervention is part of Güntzel's year-long fellowship at the Research Institute for Sustainability - Helmholtz Centre Potsdam (RIFS).
