Polar Bear Welfare and Sea Ice Loss

Polar bears are experiencing direct welfare impacts from climate-driven sea ice loss including starvation, increased conflict with humans, and reduced reproductive success.

Key Facts

Arctic sea ice extent has declined by about 13 percent per decade since the 1970s
Polar bears require sea ice to hunt ringed seals their primary food source
Longer ice-free seasons force bears ashore where food options are severely limited
Starving bears entering communities face lethal removal as conflict animals
Polar bear body condition has declined measurably in several monitored populations

Welfare Considerations

Polar bear welfare is a direct casualty of climate change in a way that is both scientifically documented and viscerally tangible. Longer ice-free seasons mean longer fasting periods for bears, particularly females nursing cubs. Chronically undernourished bears show reduced immune function, cub mortality, and behavioral changes consistent with chronic stress. Bears entering human communities seeking food face lethal removal. This is not a future scenario — measurable welfare decline is already occurring across multiple polar bear subpopulations.
