Disappearing sea ice is taking a toll on the youngest members of the largest species of penguins, new research finds. Emperor Penguins (Aptenodytes forsteri) are born into the darkness of Antarctica’s long winter and then fledge around December, when the days of the Southern Hemisphere’s summer are longest.
