Almost 90 per cent of Indians are more vulnerable to public health issues, food shortages and increased risks to deaths due to the deadly heat waves fuelled by climate change in 2022, research by the University of Cambridge revealed on Thursday.

The study, published in the ‘PLOS Climate’ journal at a time when several states are already in the throes of rising temperatures, points out that India currently uses a national Climate Vulnerability Indicator (CVI) to measure climate vulnerability and make plans for the adaptation.
