Penguin population could drop 60 percent by end of the century

Approximately 30 percent of current Adélie penguin colonies may be in decline by 2060, researchers predict, and approximately 60 percent may be in decline by 2099. The declines are associated with warming -- many regions of Antarctica have warmed too much and further warming is no longer positive for the species.
