Indigenous Arctic Knowledge

The Arctic is not uninhabited. Inuit, Sami, Nenets, and Chukchi peoples have lived here for thousands of years, building survival knowledge that still impresses modern scientists. Inuit languages, for example, carry a rich vocabulary for distinguishing types of snow and ice, each tied to different travel and hunting conditions.

Traditional igloos are engineering marvels. The curved ice blocks form a self-supporting dome, and trapped body heat can lift the inside temperature tens of degrees Celsius above the outside air. These cultures prove that humans can thrive in almost any geography, given enough time and ingenuity.
