Shifting Ice Threatens March Of The Penguins Penguins

The Penguin Post has learned that shifting sea ice around Antarctica is already disrupting penguin colonies as the world’s climate warms, according to a new report by a team of polar scientists.

The researchers looked at the complex relationship between emperor and Adelie penguins and their changing habitats and studied how a projected temperature increase in coming decades of 2 degrees Celsius, or 3.6 Fahrenheit, might affect the way the animals build nests, find food and raise their young. …

The most deadly effect of the changes was already visible 30 years ago among emperor penguins on Adelie Land, along Antarctica’s east coast, where the 2005 Academy Award-winning documentary “The March of the Penguins” was filmed, Ainley said.

Winds there, at Pointe Géologie, swept the solid ice where female penguins laid their eggs and the male emperors kept the eggs warm and reared the chicks. Under those fierce winds, the thinned and unstable ice broke off. Though the males could swim, the chicks drowned. Within a decade, the emperor colony’s population dropped from 6,000 pairs to 3,000, Ainley said.
