ANTARCTICA: 5 MAY 2017: Climate change is affecting Antarctica’s penguin population, which is reducing rapidly, especially in regions where the impact of global warming is felt the most. The population is expected to plummet by 60 percent at the end of this century. The main reason for their plummeting population is the warming of sea water. Even though the penguins cannot survive extremely cold temperatures, the warmer places too cannot let them live, explain experts, relying on global climate model projections and satellite data for their study. About 30 percent of Adélie colonies in Antarctica may be wiped out by 2060, and 60 percent by 2099.
