Polar Bear Welfare in a Warming Arctic

Climate change is fundamentally altering polar bear welfare by reducing sea ice habitat, increasing fasting periods, and forcing greater human-wildlife conflict as bears seek terrestrial food.

Key Facts

Polar bears depend on sea ice to hunt ringed and bearded seals — their primary food source
Arctic sea ice has declined approximately 13% per decade since satellite monitoring began
Extended ice-free periods force polar bears into longer terrestrial fasting that depletes body condition
Female polar bears with poor body condition have reduced reproductive success and cub survival rates
Human-bear conflict incidents are increasing as bears spend more time near coastal communities
Some polar bear subpopulations are already declining in both body size and reproductive output

Welfare Considerations

Polar bear welfare is directly threatened by climate change in ways that are measurable, ongoing, and worsening. Extended fasting periods cause physiological stress, reduced immunity, and increased mortality — particularly affecting cubs and reproductive females. The welfare costs of starvation are severe and prolonged. As ice-free periods lengthen, bears are forced into behavioral adaptations including terrestrial foraging on bird eggs and whale carcasses that partially compensate nutritionally but cannot fully replace the energy-dense seal diet. Human-bear conflict creates additional welfare risks from deterrence activities, hazing, and mortality. Meaningful polar bear welfare improvement requires climate action — no localized conservation measure can compensate for the loss of the sea ice ecosystem.
