Global climatic events like the Roman Warm Period, Medieval Climate Anomaly, and the Little Ice Age may have had significant impacts on India's landscape, vegetation, and socio-economic growth, with abrupt shifts in the Indian Summer Monsoon (ISM) coinciding with these climatic events, a study by Indian researchers has found. The study by the Wadia Institute of Himalayan Geology, an institute of the Department of Science & Technology, shows wet monsoon conditions in the North-Western Himalaya between 1200 and 550 BCE. This condition prevailed till 450 AD, coinciding with the Roman Warm Period. It was followed by reduced precipitation and a weak ISM till 950 AD and then strengthened during the Medieval Climate Anomaly between 950 and 1350 AD. During the Little Ice Age, there was a pronounced reduction in monsoon precipitation. The study carried out with lake sediments from Rewalsar Lake, a freshwater lake in Mandi district of Himachal Pradesh, could resolve the long debate among ...
