Climate Change may have led to the Fall of Indus Valley Civilization.

According to an Indian-origin scientist, Nishant Malik, from Rochester Institute of Technology (RIT) in the US, has linked the change in climate for rise and fall of the ancient Indus Valley civilization by analyzing data of 5,700 years from North India. He used a novel mathematical method to study the ancient climate patterns to impart insights into past climates by observing indirectly. The research was published in Chaos: An Interdisciplinary Journal of Nonlinear Science, observed that scientists could come up with the data of monsoon rainfall in the region for the last 5,700 years and then they could calculate the existence of specific chemical forms in stalagmite mineral deposits in the caves of South Asia region. Though he indicated that it might be a challenging task as it carries some noise and uncertainty with it.

The study claims that though there are many theories which try to throw some light on the decline of Indus Valley Civilization like nomadic Indo Aryans and earthquakes but climate change theory may be the most valid scenario. Though Nishant Malik told that there was no mathematical evidence till the new hybrid approach was incorporated. He backed the theory based on his research that there was a huge change in monsoon patterns before the rise and it totally reversed before fall of civilization attesting to the theory that climate change had caused the fall.

The scientists from Rochester Institute of Technology trust that the new method will give a new direction to evolve more mechanized techniques to find changes in ancient climate details which may lead to more ground- breaking and relevant theories.
