Elizabeth K. Fitch, : Rapid Climate Change and the Collapse of the Maya CivilizationAlmost overnight, from a historical standpoint, the Maya Civilization collapsed. The suddenness of this collapse has been shrouded in mystery until recent explorations of sediment records have shed some light on the subject. Cores from lakes in the Yucatán and from the Cariaco Basin off the northern coast of Venezuela reveal overall favorable climatic conditions during the development and height of the Maya. The cores also show that the time period coinciding with the collapse of the Maya was an extended period of drought punctuated by shorter intense droughts in A.D. 810, 860, and 910. These periods of drought, considered rapid climate changes, may have triggered the collapse of the Maya at a time when their population was stretching the limits of the environment.
