Polar bears are facing unprecedented welfare challenges as climate change reduces sea ice and disrupts their hunting season. Understanding their welfare status informs conservation and climate policy.
Polar bear welfare is inextricably linked to climate change outcomes. As ice seasons shorten, bears spend longer fasting periods on land, drawing down fat reserves accumulated during hunting seasons. Declining body condition is directly measurable and represents chronic nutritional stress. Female bears with insufficient fat reserves fail to produce cubs, or produce cubs that die early due to insufficient milk. This represents welfare harm at both individual and population levels. Conflict with human communities increases as food-stressed bears enter settlements seeking alternative food sources, often ending in lethal bear removal. Climate action is literally a polar bear welfare issue.
