Polar Bear Welfare and Sea Ice Loss Under Climate Change

Polar bears are highly dependent on sea ice for hunting seals and face the most severe individual welfare consequences of Arctic sea ice loss from climate change.

Key Facts

The global polar bear population is estimated at 20,000-25,000 individuals across 19 subpopulations
Sea ice extent and duration directly determine seal hunting access and reproductive success
Extended ice-free periods force bears onto land where food resources are scarce
Body condition indices have deteriorated in multiple subpopulations with increasing ice-free seasons
The IUCN classifies polar bears as Vulnerable with declining population trajectory

Welfare Considerations

Polar bear welfare impacts from sea ice loss are documented across multiple subpopulations as declining body condition, reduced cub survival, and increased starvation mortality. Prolonged fasting on land during extended ice-free seasons causes significant physiological and welfare stress. Cubs born to nutritionally compromised females have reduced survival through the first year. Female bears with cubs are particularly vulnerable as they face competing demands of cub nursing and fat reserve maintenance. The welfare of polar bears is directly and demonstrably linked to greenhouse gas emissions — climate action is the most fundamental welfare intervention available.
