Siku On the front lines of climate change, Arctic communities use tech to keep tradition alive Arctic Indigenous communities are fighting to preserve their culture in the face of the climate crisis. Katie Collins Dec. 22, 2020 Among the Inuit Nunangat communities in far northern Canada, there's a saying: If you smack the ice with your harpoon and it doesn't go through on the first hit, it's thick enough to walk on. If you can hit it three times without it breaking, it's good for snowmobiles. And if you can hit it five times, it can support anything. This valuable advice has kept generations of Inuit hunters safe as they navigate the frozen sea in search of whales, seals, fish and birds. But as climate change disrupts the rhythms of life in the Arctic, it's becoming increasingly difficult to apply traditional knowledge to the sea ice, weather patterns and the seasons. The Arctic as a whole is warming twice as fast as the rest of the world, and scientists estimate that Arctic summer sea ice could totally disappear by the year 2040.
