Summary

The International Commission on Stratigraphy recently announced the creation of a new unit in the scale of geological time, the Meghalayan Age, from 4200 years before present, or 2200 BCE, to the present. The Commission explains that this period began with a two-centuries-long megadrought that caused the collapse of civilizations in Egypt, Greece, Syria, Palestine, Mesopotamia, the Indus Valley, and the Yangtze River Valley (1). However, there is little archaeological evidence for such sudden, widespread civilizational collapse.
