Environmental Woes of Tierra del Fuego -- Climate Change

Dr. Harald Biester and students Oscar Baeza and Sascha Birkenstock push a sharpened sleeve into a bog at the foot of the Gran Campo Nevado ice field to remove a core from its 10,000-year-old peat. The region's many bogs trap pollens and chemicals dispersed through the air and water. Peat cores take scientists back thousands of years with each foot of depth.
