IntroductionArctic environmental change and intensified extractive/governance pressures are often framed through prediction, risk management, and expert control. This article argues instead that Indigenous cosmopolitical practices show how action becomes possible when inherited knowledge, human authority, and stable environmental cues cannot be assumed.MethodsWe bring cosmopolitical and multiple-worlds theory into dialogue with long-term ethnographic fieldwork, remembered field conversations, oral histories, whaling discourse, and ceremonial narratives from Eveny, Yup’ik, Iñupiaq, and Coast Salish contexts. We read these materials comparatively to ask how humans, animals, weather, ice, land, spirits, memories, and institutions participate in judgement, movement, refusal, and obligation.ResultsAcross the cases, cosmopolitics emerges less as an abstract recognition of plural ontologies than as the co-production of action. Yup’ik dog-team and Eveny reindeer accounts show authority redistributed under pressure when animals refuse unsafe human commands. Eveny border-crossing and cryospheric memory stories reveal a politics of perception in which snow, ice, light, cold, and animal sensing shape what can be seen, hidden, trusted, or acted upon. Iñupiaq whaling ethics show that whale–human relations depend on maintaining conditions of welcome through sharing, restraint, attention, and collective accountability amid regulatory, extractive, scientific, and media scrutiny. Eagle/Wolf and ceremonial narratives extend collaboration beyond human-centred reciprocity toward transformation across species, elements, and generations.DiscussionBuilding on Stengers’ demand for ralentissement and grounding it in the Eveny concept of nyamnin, we show that hesitation is not the opposite of action. Stopping, waiting, yielding, refusing, hiding, sharing, rerouting, and withholding judgement can be practical modes of safety and political refusal. Cosmopolitics thus names an operative practice for living with volatility: a way of remaining answerable to more-than-human warnings and obligations while challenging technocratic regimes that mute whales, reindeer, dogs, ice, land, and the dead within singular causal explanations.
