An Indian-origin scientist, Nishant Malik, has suggested that the shifting monsoon patterns led to the fall of the Indus Valley Civilisation
According To Indian Express, The analysis by Nishant Malik from Rochester Institute of Technology (RIT) in the US used a new mathematical method to study ancient climate patterns in North India over time, providing insights about past climates using indirect observations.
Malik developed a mathematical method to study paleoclimate time series. The research has been published in Chaos: An Interdisciplinary Journal of Nonlinear Science
The analysis showed there was a major shift in monsoon patterns just before the dawn of the civilisation and that the pattern reversed course right before it declined.
