Wherever you are in Greenland, the way the wind feels can place you in relation to the sea and the ice.

The Inuit have relied for nearly a thousand years on tiny nuances in the breeze to guide them on foggy, starless nights, and they gave these winds special names. A single word, isersarneq, communicates something like: “This is a wind in the fjord that comes in from the sea, and it can be hard to get home, but once you get out of the fjord, it’s nice weather.”

But recently, as the winds change and become unpredictable, these terms are disappearing.
