Environmental Woes of Tierra del Fuego -- Climate Change

A layer of volcanic ash stripes a core of peat taken from the bog. Deposited 3,800 years earlier when the Mt. Burnay volcano erupted 60 kilometers away, the ash marks a catastrophic event that will give the scientists clues about how the environment reacted to change in the eruption's aftermath. The team compares information from peat layers with other parts of the interdisciplinary study. "In one of the lakes we drilled here this was followed by extreme erosion," Dr. Rolf Killian notes. Trees died and washed into lakes. Moss in the bog was killed.
