Polar Bear Welfare and Climate Change: An Arctic Crisis

Polar bears are among the most iconic victims of climate change. Shrinking sea ice is reducing hunting opportunities, causing nutritional stress, increased human conflict, and long-term population decline across most subpopulations.

Key Facts

Polar bears depend almost entirely on sea ice as a platform for hunting ringed seals, their primary prey
Arctic sea ice extent has declined by approximately 13% per decade since satellite measurements began in 1979
Of 19 recognised polar bear subpopulations, 3 are declining, 6 are of concern, and the trend for most is negative
Body condition of female polar bears in the southern Beaufort Sea has declined significantly since the 1980s
Longer ice-free periods force polar bears into nutritional fasting states that reduce reproductive success and cub survival
Human-bear conflict is increasing as bears spend more time onshore near communities during ice-free seasons
Current projections suggest that under high-emissions scenarios, frequent summer sea ice could disappear by 2050

Welfare Considerations

Polar bear welfare is increasingly determined by climate trajectory. Nutritional stress from reduced hunting opportunities causes chronic physiological harm — bears in poor body condition have weakened immune systems, reduced reproductive success, and higher mortality rates. Cubs born to nutritionally compromised females have lower survival rates. Longer onshore periods increase conflict with humans, resulting in bears being killed in defence of life situations or relocated — both welfare-negative outcomes. The welfare of individual polar bears is inseparable from the broader climate crisis: addressing emissions is the only meaningful long-term welfare intervention available. Short-term measures including conflict management and supplemental feeding are palliative at best.

What You Can Do

Support climate change policy advocacy as the single most important action for polar bear long-term welfare
Donate to Polar Bears International which funds polar bear research, monitoring, and climate advocacy
Support conflict reduction programmes in Arctic communities that protect both humans and bears during onshore seasons
Avoid purchasing products from industries with high Arctic development footprints that compound sea ice loss
Learn about polar bear ecology and the specific mechanisms through which climate change affects their welfare and survival
