The study estimates that by 2100, at least two-thirds of emperor penguin colonies will have dramatically declined.
Over a million Adélie penguins were found living off the coast of Antarctica, on the remote Danger Islands. Just 100 miles away in the west Antarctic, the same species is in decline due to sea ice melt.
Over two expeditions, Robert F. Scott discovered and investigated the first breeding colony of emperor penguins. This broadened our knowledge about this species.
The first person to describe emperor penguins was Johann Reinhold Forster. He had spotted a few during James Cook's voyage.
