Resumen de Tibet's primeval ice
High on the western edge of the Tibetan Plateau, scientists last fall retrieved what may be the oldest ice on the planet. Ice cores drilled at the Guliya ice cap hold a record of ancient climate on the plateau that could stretch back nearly a million years. Guliya is thought to be the best record of midlatitude climate during the last ice age, and its ice may well turn out to be a Rosetta Stone for interpreting how Asia responds to a changing climate. The stakes are enormous: The Tibetan Plateau is the engine that drives the Indian monsoon and it gives rise to major rivers that are the lifeblood of more than 1.4 billion people.
