The Arctic is warming twice as fast as the rest of the world. This is putting its unique ecosystem at risk, and with it the existence of Europe’s only recognised indigenous people, the Sami, who have lived in the Arctic for millennia. Increasingly unpredictable and extreme weather is jeopardising Sami livelihoods and their rights as indigenous people. The Sami have a clear message for decision makers, from the front lines of climate change: now is the time to act.
