Wild Polar Bear Welfare: Climate Change and Sea Ice Loss

Polar bears face existential welfare threats from sea ice loss driven by climate change, with declining body condition, increased fasting periods, and human conflict creating growing individual suffering.

Key Facts

Sea ice coverage in the Arctic has declined approximately 13% per decade since satellite monitoring began
Polar bears depend on sea ice for hunting ringed seals, their primary prey
Declining ice extent forces longer fasting periods and reduced body condition in many subpopulations
Some western Hudson Bay polar bear subpopulations have shown 30% population decline since the 1980s
Polar bear-human conflict increases as bears spend more time on land near human communities
Maternal den success rates decline with reduced snow coverage and earlier den-opening temperatures

Welfare Considerations

Polar bear welfare is inextricably linked to climate change - the most significant and unavoidable welfare threat to this species. Longer fasting periods as sea ice disappears mean extended periods of energy deficit, affecting body condition, reproductive success, and cub survival. Extended time ashore forces bears into conflict with human communities, resulting in lethal control of problem animals. Cubs born to nutritionally depleted mothers face reduced survival odds. Climate action is fundamentally a polar bear welfare issue alongside its human dimensions.

What You Can Do

Support ambitious climate action policies that reduce Arctic warming
Donate to polar bear conservation organizations like Polar Bears International
Reduce personal carbon footprint with particular attention to high-impact choices
Support communities in polar bear range countries developing non-lethal conflict management
