Climate change is disrupting penguin breeding, foraging, and survival across both Antarctic and temperate species.
Climate change creates multiple welfare pathways for penguin populations. Chick mortality from rainfall and flooding during critical development periods causes distressing deaths by hypothermia and starvation. Adults foraging further for reduced prey experience nutritional stress. Sea ice changes disrupt Emperor penguin breeding on annual ice that no longer forms reliably. Climate policy is penguin welfare policy.
