Climate-driven sea ice loss is causing measurable welfare impacts on individual polar bears through increased fasting periods, drowning risk and reduced reproductive success.
Individual polar bears are experiencing measurable welfare impacts from climate change that are visible in declining body condition, increased cub mortality and changed behaviour. Bears that must swim long distances between ice floes in open water become exhausted, and cubs may drown or separate from their mothers during these crossings. Extended fasting on land causes metabolic stress and reduces immune function. Female bears emerging from dens with cubs in declining body condition have less milk for their young and may abandon cubs they cannot support. These are individual welfare impacts experienced by wild animals that are directly attributable to human greenhouse gas emissions.
