Summary Antarctic GlaciersDuring the southern summer, Mark Horstman and Dr Paul Willis travelled to opposite sides of Antarctica. Their purpose: to witness just how the east and west of the continent are reacting differently to climate change.Antarctica contains around 90% of the world's snow and ice. But climate change and ocean warming are causing the giant ice shelves that buttress the glaciers to break down. This in turn is allowing the glaciers to slide faster into the sea.Otto NordenskjoeldAround the turn of the 20th century in what is known as Antarctica's Heroic Age, 16 expeditions set off from 8 different countries for the icy continent. While names like Mawson, Scott and Amundsen are well known, it's easy to overlook the legacy of Antarctica's other early explorers. Dr Paul Willis takes up the story of Otto Nordenskjoeld. His epic ordeal rivals that of Shackleton and he remains one of the most significant pioneers of Antarctic research. Southern Ocean SentinelThe Southern Ocean stretches right around the planet, linking the Atlantic, Pacific and Indian oceans. It's like a carbon sponge that helps buffer the rest of the world from global warming. But it's also the first to feel the impacts of climate change. Mark Horstman goes aboard the Aurora Australis with scientists studying tiny plankton for clues about the pace and effects of climate change in the Southern Ocean.PRODUCTION DETAILS:Executive Producer: Nick Lee; Series Producer: Matt Scully.
