Polar Bear Climate Welfare | Animal Welfare Hub

How climate change is degrading polar bear welfare through sea ice loss and what conservation responses can help.

Key Facts

Arctic sea ice extent has declined 13% per decade since satellite records 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 force polar bears to fast for longer periods, causing nutritional stress and reproductive decline
Hudson Bay polar bear populations have declined approximately 30% since 1987, primarily due to earlier ice breakup
Climate projections suggest up to two thirds of polar bear subpopulations could decline significantly by 2050

Welfare Considerations

Polar bear welfare presents the starkest available example of climate-driven wildlife welfare harm. The sea ice that polar bears depend on is disappearing faster than species can adapt, forcing individual bears into longer fasting periods, longer swims to reach remaining ice, and reduced reproductive success. These are welfare costs at the individual level — real hunger, exhaustion, and reproductive stress experienced by individual bears — as well as population-level conservation concerns. The connection between individual bear welfare and global greenhouse gas emissions is direct: every tonne of CO2 emitted contributes to the sea ice loss that extends polar bear fasting seasons and reduces their survival probability.

What You Can Do

Reduce your personal and household carbon emissions as a direct welfare intervention for polar bears and other climate-affected species
Support Polar Bears International and WWF's polar bear conservation programmes
Advocate for ambitious greenhouse gas emission reduction policy at national and international levels
Avoid eco-tourism that stresses polar bears — choose operations with zero-disturbance guidelines
Engage with climate communication about wildlife welfare impacts alongside human impacts to broaden climate concern
