Climate Change
Definition
Climate change is the dominant long-term threat to penguin species worldwide. Rising ocean temperatures shift prey distributions, reduce sea-ice habitat, and increase the frequency of extreme weather events. Emperor penguins could lose 80% of their colonies by 2100 under high-emission scenarios as fast ice becomes unreliable. Temperate-zone species like the Galapagos and African penguin face prey collapses driven by warming waters. Climate change also interacts with other threats — fishing pressure, disease, and habitat loss — to amplify overall extinction risk.
Related Terms
Sea ice extent refers to the total area of ocean covered by sea ice at a given time, and it is one of the most important environmental variables for Antarctic penguin species.
El Nino is a periodic warming of sea surface temperatures in the central and eastern tropical Pacific Ocean that disrupts global weather patterns.
Population trend describes whether a species is increasing, stable, decreasing, or unknown over a defined time period, typically three generations.
