Half of Adélie penguins could be wiped out by global warming

Global warming may cause massive drops in the population of Adélie penguins in Antarctica, new climate data suggests. The tuxedo-clad birds breed on rocky, ice-free ground, and as glaciers receded over millions of years, Adélie penguins have reclaimed once icebound land for breeding. But the climate may have reached a tipping point, and future warming will likely fuel declines in Adélie colonies, the researchers found… Source
