Host Kathleen Stephenson interviews Fen Montaigne, author of "Fraser's Penguins: A Journey to the Future in Antarctica." Journalist and author Fen Montaigne discusses the beauty of Antarctica, the lives of the Adelie penguins and the details of the work of scientist Bill Fraser. Fraser has worked in Antarctica since 1975. He has documented how the part of Antarctica that is home to Adelie penguins and other wildlife has warmed faster than almost any place on earth. No creature has been more profoundly affected by the changes than the Adelie, who depends on sea ice to survive.
