Scientists core into California's Clear Lake to explore past climate change

(University of California - Berkeley) One of the oldest lakes in the world, Clear Lake in northern California has deep sediments that contain a record of the climate and local plants and animals going back perhaps 500,000 years. UC Berkeley scientists are drilling cores from the sediments to explore 130,000 years of this history and fine-tune models for predicting the fate of today's flora and fauna in the face of global warming and pressure from a growing human population.
