Polar bears are uniquely dependent on sea ice for hunting. Climate change is causing rapid ice loss that is creating welfare and conservation crises for this iconic species.
Wild polar bear welfare is deteriorating in direct proportion to sea ice loss. The mechanism is straightforward: bears that evolved to hunt seals on sea ice for much of the year are forced into extended land fasting as ice season shortens. Nutritional stress affects body condition, reproductive success, and cub survival. Emaciated bears foraging near human communities face management interventions including capture and relocation that cause acute welfare harm. Fatal encounters with humans are increasing as bear desperation drives greater risk-taking. The welfare trajectory for individual polar bears under current climate projections is clearly negative. Unlike most wildlife welfare problems, the primary solution — climate action — lies outside the conventional toolkit of wildlife management.
