India may have seen a number of record-breaking warm years in the recent decades, but there has been no let-up in the extreme cold waves in the country despite global warming, an IITM study has indicated. The analysis, led by IITM scientists Raju Mandal and Susmitha Joseph, took into account the number of cold wave events in the last seven decades, 1951–2022, and found that more cold wave days are occurring in the recent decades than in the previous ones.
