Polar Bear Welfare and Climate Change

Polar bears are among the most visible wildlife welfare victims of climate change, facing starvation, drowning, and increasingly poor body condition as sea ice shrinks.

Key Facts

Arctic sea ice extent has declined by approximately 13% per decade since satellite records began
Polar bears depend on sea ice as a platform for hunting seals — extended ice-free periods cause prolonged fasting
Body condition of Western Hudson Bay polar bears has declined significantly since the 1980s
Drowning incidents occur when bears attempt to swim between shrinking ice floes across greater open water distances
Captive polar bear numbers cannot compensate for wild population losses — captive bears require vast spaces

Welfare Considerations

Polar bears provide a visible and compelling illustration of how climate change translates into animal welfare harm. The declining sea ice that forces bears into longer fasting periods causes the chronic welfare harms of hunger, nutritional stress, reduced reproductive success and increased mortality in cubs and elderly individuals. Bears swimming long distances between shrinking ice floes face exhaustion and drowning. Mothers in poor condition produce smaller, less viable cubs. These are not abstract population statistics but individual animal welfare harms happening to millions of bears across one of the world's most extreme environments. Climate action is therefore the most impactful single intervention for polar bear welfare.
