Researchers have studied the emperor penguins around Pointe Géologie, in Terre Adélie, since the 1960s.

The Adélie penguin, for example, was first identified by a naturalist who joined an 1837 expedition to southeastern Antarctica led by the French explorer Jules Dumont d’Urville, who named the place Terre Adélie after his wife.

For more than 60 years, scientists have extensively studied one Emperor Penguin colony in Antarctica, called Terre Adélie.

In 2012, the two scientists and their team published a study in the journal Global Change Biology, that found that the Terre Adélie penguin population could decline by 80 percent by the end of this century.

For their newest study, the researchers expanded on this work, using the established population models from Terre Adélie to project how all 45 of Antarctica’s known colonies of emperor penguins would respond to future climate change.
