From the vantage point of space, scientists have spent three decades reading the color of penguin waste across Antarctica — and what they have found is a continent quietly unraveling. Adélie penguins, those ancient inhabitants of the ice, are being pushed from nourishing fish toward scarcer, less sustaining krill as the sea ice that structures their world retreats. This first continental-scale food-web study, conducted by researchers from Clemson, UC Santa Cruz, NASA, and others, transforms satellite imagery into a kind of ecological confession — a record of what climate change is doing to lif

Adélie penguin populations face existential risk from climate-driven ecosystem changes affecting food availability and nutritional intake.
