The geopolitical landscape of the Arctic has shifted dramatically following Russia’s full-scale invasion of Ukraine, which paused over 25 years of traditional Arctic Council-informed and -guided cooperation with Arctic Indigenous Peoples, Arctic Nations, and Observer States. This break in Arctic diplomacy, particularly the cessation of scientific cooperation, raises crucial questions about the future of Arctic collaboration on challenges facing the Arctic and the planet. In light of this, our project seeks to present a series of informed scenarios that may help guide Arctic diplomacy and cooperation as we look toward 2032, a year that will also mark the 5th International Polar Year (IPY-5).
