Antarctica Penguin Perfect (For Now)

The Penguin Post has learned that Antarctic sea ice levels are perfect for emperor penguins.  That according to researchers, who have found the frozen continent has in the past been (if you can believe) too cold for the bird. A team of Australian researchers, including scientists from the University of Tasmania and the Australian Antarctic Division, has been investigating how emperor penguin numbers have varied over centuries.
