Heatwave duration to increase in most areas by 2060: IMD report

India could see an increase in the duration of heatwaves by 12-18 days by 2060, according to a report by the India Meteorological Department (IMD). The report recommends a response plan for heatwaves that includes cultural, institutional, technological and ecosystem-based adaptation strategies. Heatwaves have claimed more lives in India than other natural hazards, except tropical cyclones, IMD said. The report used data from 1961-2020 to decipher heat wave climatology and occurrence.
