Penguin colonies across the Southern Ocean face escalating welfare crises from climate-driven changes in sea ice, prey availability, and storm frequency affecting breeding success.
Penguins facing food scarcity from krill decline endure progressive starvation stress, reduced breeding success, and higher chick mortality. Colony-wide breeding failures caused by early ice melt or storms can kill thousands of chicks simultaneously. Individual penguins experience the welfare consequences of systemic ecological disruption driven by climate change. Addressing climate change is the most important long-term intervention for penguin welfare alongside protecting Antarctic marine protected areas.
