The period began 4,200 years ago with an abrupt mega-drought (ICS)We are living in the Meghalayan Age, a new chapter in the history of our planet, according to geologists.
The International Commission on Stratigraphy (ICS) has classified the past 4,200 years as a distinct age – the Meghalayan – in geological terms.
It’s a subdivision of the Holocene era, one of three approved by the International Commission on Stratigraphy.
The Meghalayan began with a huge drought that disrupted civilisations in Egypt, Syria and China, the geologists say.
The researchers say, ‘Agricultural-based societies that developed in several regions after the end of the last Ice Age were impacted severely by the 200-year climatic event that resulted in the collapse of civilizations and human migrations in Egypt, Greece, Syria, Palestine, Mesopotamia, the Indus Valley, and the Yangtze River Valley.

The International Commission on Stratigraphy approved proposals for two other ages: the Middle Holocene Northgrippian Age and the Early Holocene Greenlandian Age with beginnings defined at climatic events that happened about 8,300 years and 11,700 years ago, respectively.
The three ages comprise the Holocene Epoch, which represents the time since the end of the last Ice Age.
