Climate-driven sea ice loss is transforming the welfare of polar bears across the Arctic, forcing longer fasting periods and increasing human-wildlife conflict.
Polar bears are experiencing in real time what climate change means for individual animal welfare. Reduced sea ice access means longer fasting periods, declining body condition, lower cub survival, and increased desperation that drives bears into human settlements. The welfare consequences of climate change for wildlife are often overlooked in policy discussions focused on population-level biodiversity metrics. For individual polar bears, the lived experience of a warming Arctic is one of chronic food stress and increasing mortality risk.
