The view from Kongsfjorden, Svalbard, is endless snow-covered mountains and glassy, frigid water. You need to travel roughly 400 miles west from the remote Norwegian archipelago to reach the northeast coast of Greenland.
Kongsfjorden, home to one of the few human settlements on Svalbard, has been studied intensively. It's a "natural laboratory" of Arctic climate change, one that has suggests that the ecosystems living in these icy water have so far managed a surprising amount of resilience in the face of rising temperatures, according to a paper in Nature Climate Change. But the long-term picture suggests a future that is probably not so rosy.
Layers of complexity
As the sea ice melts in the Arctic—which is warming substantially faster than the global average—the food webs living in these icy waters are in peril.
