Climate change has been linked to a multitude of troubling trends, like melting polar ice caps, rising sea levels, and more extreme weather. And while these changes are bound to have a profound impact on future life on Earth, the disturbing realities of this phenomenon are already being felt -- it's killing baby penguins.
In the world's largest Magellanic penguin colony on Argentina's Punta Tombo peninsula, home to more than 200,000 breeding pairs, changes in both temperature and rainfall are taking a deadly toll. According to the results of decades of study, researchers found that these shifts have led to an increase in mortality rates among penguin chicks.
University of Washington biology professor P. Dee Boersma says that young chicks who have yet to shed their downy feathers are particularly vulnerable to heavy rainfall which can soak through to their skin causing hypothermia. In the last 30 years, Boersma has recorded an increase in storms over the normally arid region, in some years causing nearly half the colony's chick deaths.
