Arctic species face existential welfare threats from climate change as sea ice loss alters the fundamental conditions of their existence.
Arctic wildlife welfare is determined by climate at a scale that individual or even national action cannot address. Polar bears facing sea ice loss experience chronic starvation as access to their primary prey shrinks. Walruses experiencing crowd deaths on coastal haul-outs face acute traumatic welfare events of unprecedented scale. The welfare response to Arctic species decline requires climate action at global scale — reducing greenhouse gas emissions — alongside specific protections for vulnerable populations during the transition.
