Environmental Woes of Tierra del Fuego -- Climate Change

Dr. Gino Casassa and Dr. Harald Biester haul equipment over a rough trail to the Lengua glacier, passing a huge peat bog that acts as a repository for thousands of years of data on vegetation and atmospheric conditions. Wood samples washed out of the bog by the river pictured will be carbon dated, and the rings in the wood -- preserved in the oxygen-starved depths of the bog for thousands of years -- will be studied for ancient weather patterns.
