Extreme weather events to rise manifold in india due to climate change: IIT Gandhinagar study
The frequency of extreme weather events such as floods and heatwaves is projected to rise manifold in India in the future due to climate change, according to a study by researchers at the Indian Institute of Technology, Gandhinagar. The research team studied the period from 1951 to 2020 to quantify India's risk of sequential extremes -- heatwaves in the summer and extreme rainfall in the following summer monsoon season over the same regions.
The study, published in the One Earth journal on Friday, found that the risk will increase significantly under the warming climate and variability in the El Nino-Southern Oscillation (ENSO) -- a recurring climate pattern involving changes in the temperature of waters in the central and eastern tropical Pacific Ocean.
The researchers noted that climate mitigation and reduction in vulnerability could help in reducing the risk. The study highlighted that mega-heatwaves occurred during the summer of 1995 and 1998, with 20 per cent and 8 per cent of the country being affected by sequential extremes.
The researchers noted that a considerable reduction in vulnerability by improving socioeconomic livelihood and infrastructure will be needed to maintain the same risk (at 1.5 degrees Celsius global warming level) at higher global warming levels.
