Adélie penguins are one of two true Antarctic penguins, and they are threatened by a changing climate.
Antarctica Could Lose Most of Its Penguins to Climate Change
A new study finds significant impact, and a possible silver lining, for the iconic birds over the next century.
Published Wednesday in Scientific Reports, the study, led by oceanographer Megan Cimino, found that up to 60 percent of the current Adélie penguin habitat in Antarctica could be unfit to host colonies by the end of the century.
The Adélie penguin is one of two true Antarctic penguins—the other being the emperor penguin (Aptenodytes forsteri)—and it inhabits the full extent of the continent. The penguins nest on land during the austral (southern) summer, and migrate during the winter to the edge of the sea ice, where they are able to feed at sea.
Using a combination of field survey data and high-resolution satellite imagery, the researchers were able to stitch together 30 years of colony data, from 1981 to
