Why Are Emperor Penguins Endangered?

Emperor penguins are not listed as endangered as of 2015, but are expected to be listed as such soon due to the rising temperatures in Antarctica. These temperatures eliminate the sea ice that emperor penguins use as a resting place as well as a place to find their main source of food, which is krill, reports the Telegraph.

The Intergovernmental Panel on Climate Change (known as the IPCC) reported that it is believed that approximately 66 percent of all emperor penguin colonies will see their numbers decrease in half by 2100. However, too much sea ice can also be a bad thing for penguins. If there is too much sea ice present then the penguins must leave their young chicks for a much longer period of time in order to get to the ocean and hunt for food.
