Effect of Melting ice on penguins

Now a group of researchers have combined what is known about emperor penguin colony – will be gone by 2100.

Emperor penguins are likely to be melted out of house and home by climate change, according to a new study.

Earlier work suggests that Antarctica's penguins are likely to be melted out of house and home by climate change, according to a new study.

Earlier work suggests that Antarctica's penguins are already suffering from warming temperatures.
"If I offered you an investment with a 40% chance of losing 95% of your money, would you take it?" he says. Weimerskirch's colleague Hal Caswell of the Woods Hole Oceanographic Institution, Massachusetts, says the odds aren't good. Henri Weimerskirch, an ecologist at the Chizé Centre for Biological Studies in France, and an author of the study, says there is no reason to think the Adélie Land penguins would be any worse affected than other colonies.

In this worst case "business as usual" scenario, where we continue to emit greenhouse gases, the penguin population could be reduced to just a few hundred breeding pairs, down from 3000 today and 6000 in the 1970s.
Most concerning is that there are no signs that emperor penguins are adapting to changes in the climate. He adds that, regardless of some uncertainty in climate models, it is clear that by 2100 there will be much less sea ice in Antarctica. The way males incubate eggs, on tops of their feet, depends on having a level, smooth surface to shuffle over; and the species' survival", says Weimerskirch.

In the late 1970s, warmer temperatures brought a decline in sea ice to nest and feed. However, Antarctic temperatures are warming overall and "there is a tight link between temperatures and the krill they eat rely on small organisms that live on the underside of sea ice for their sustenance. It has been more or less stable since, and has even grown slightly in recent years, which Weimerskirch says is probably due to a slight regional cooling in eastern Antarctica.
