Polar Bear Welfare in a Warming Arctic

Polar bears are facing accelerating welfare deterioration as sea ice loss from climate change reduces access to prey, extends fasting periods, and forces increasingly long swims with welfare implications for individual bears.

Key Facts

Arctic sea ice has declined approximately 13% per decade since satellite monitoring began in 1979
Polar bears depend on sea ice as a hunting platform for their primary prey, ringed and bearded seals
Extended ice-free seasons in Hudson Bay have increased fasting duration from 4 months to 5+ months for some populations
Body condition scores in Western Hudson Bay polar bears have declined significantly over three decades
Longer swims between ice and land cause exhaustion and heat loss, particularly for cubs who may drown
Polar bear reproductive success declines sharply when females emerge from maternity dens in poor body condition
The IUCN projects that two-thirds of polar bears will be gone by 2050 under current warming trajectories

Welfare Considerations

Climate change causes welfare harm to polar bears through a cascade of interconnected mechanisms. Extended fasting periods beyond historical ranges cause muscle catabolism, immune suppression, and behavioral changes indicating poor body condition. Cubs born to thin females have reduced survival odds and face longer swims across open water that exceed their physiological capacity. Individuals forced into coastal human communities seeking food face lethal control. The welfare trajectory for polar bears under continued warming is unambiguously negative - a slow, population-wide welfare decline driven by habitat loss that no local conservation intervention can reverse without addressing the underlying climate driver.

What You Can Do

Support climate policy that limits warming to below 1.5 degrees C - this is the primary polar bear welfare intervention
Donate to Polar Bears International which funds research, advocacy, and education on polar bear conservation
Reduce your personal carbon footprint through diet, transport, and energy choices
Advocate for fossil fuel phase-out policy in your country through electoral engagement
Support Arctic marine protected areas that reduce additional stressors on already-stressed polar bear populations
