Climate Change Rocked Cradles Of Civilization

Severe climate change was the primary driver in the development of civilisation, according to new research by the University of East Anglia. The early civilisations of Egypt, Mesopotamia, South Asia, China and northern South America were founded between 6000 and 4000 years ago when global climate changes, driven by natural fluctuations in the Earth's orbit, caused a weakening of monsoon systems resulting in increasingly arid conditions.
