Emperor penguins threatened by Antarctic sea ice loss (80% decline by 2100?)

[font size=3]BOULDER—A decline in the population of emperor penguins appears likely this century as climate change reduces the extent of Antarctic sea ice, according to a detailed projection published this week.
The study, led by the Woods Hole Oceanographic Institution (WHOI), with co-authors from the National Center for Atmospheric Research (NCAR) and other organizations, focuses on a much-observed colony of emperor penguins in Terre Adélie, Antarctica. The authors conclude that the number of breeding pairs may fall by about 80 percent by 2100.
“The projected decreases in sea ice may fundamentally alter the Antarctic environment in ways that threaten this population of penguins,” says NCAR scientist Marika Holland, a co-author of the study.
The study uses a set of sophistical computer simulations of climate as well as a statistical model of penguin demographics. Building on previous work, it examines how the sea ice may vary at key times during the year such as during egg laying, incubation, rearing chicks, and non- breeding season, as well as the potential influence of sea ice concentrations on males and females.
