Polar Bear Welfare in Changing Arctic Conditions

Climate-driven changes to Arctic sea ice are creating unprecedented welfare challenges for polar bears, whose hunting ecology depends on stable sea ice platforms for accessing seal prey.

Key Facts

Arctic sea ice extent has declined approximately 13% per decade since satellite records began in 1979
Polar bears require sea ice to hunt ringed seals, their primary prey
Extended ice-free periods cause fasting that affects body condition and reproductive success
Polar bear-human conflicts increase as bears spend more time on land seeking alternative food
Maternal denning success is affected by permafrost thaw and early den emergence conditions

Welfare Considerations

Polar bear welfare is being undermined by ecosystem-scale changes driven by climate change rather than direct management decisions. Individual bears experiencing prolonged fasting periods suffer the physiological and behavioral consequences of nutritional stress - reduced mobility, increased stress hormones, and compromised immune function. While individual welfare interventions are limited, reducing the greenhouse gas emissions driving Arctic warming is the most meaningful long-term action for polar bear welfare.

What You Can Do

Reduce personal greenhouse gas emissions to contribute to Arctic climate protection
Support organizations monitoring polar bear welfare and population trends
Advocate for strong climate policies that protect Arctic ecosystems
