For almost a year, Hilde Fålun Strøm and Sunniva Sorby have lived in a tiny hunter’s cabin in the high Arctic, with no running water or electricity, and with polar bears as their nearest neighbours. They’ve battled hurricane winds, bone-chilling temperatures and months of darkness, but it’s all in an effort to raise awareness for climate change. As citizen scientists, they host video chats with classrooms around the globe, encouraging students to care about the earth’s future.
