2-degree rise in temperature may doom penguins mongabay.com October 10, 2008 2°C is Too Much cites research showing that 50 percent of the emperor penguins and 75 percent of the Adélie penguins are at risk by a 2-degree increase in temperatures. The report says loss of sea ice will impede penguin nesting and diminish krill populations, an important source of food in the Antarctic food chain. "Penguins are very well adapted to living in the cold and extreme conditions of Antarctica, so the continued increase in global temperature and resulting loss of feeding areas and nesting zones for their chicks has already led to notable reductions in their populations," said Juan Casavelos, WWF Antarctica Climate Change Coordinator. "If temperatures increase by another two degrees these icons of the Antarctic will be seriously threatened."
