The authors concluded that the use of CVI may underestimate the actual burden of climate change concerning heat, and suggested that India should consider reassessing its climate vulnerabilities to meet the SDGs. States that were categorized as "low" in CVI rankings were found to be in "danger" HI categories, indicating that heatwaves put more people at extreme climate risk across India than estimated by CVI.
The study showed that more than 90 percent of India is in the "extremely cautious" or "danger" range of heatwave impacts through HI, otherwise considered "low" or "moderate" vulnerability through CVI. They then compared India's progress in SDGs over 20 years (2001-2021) with extreme weather-related mortality from 2001-2021. The researchers accessed a publicly available dataset on state-level climate vulnerability indicators from the government's National Data and Analytics Platform to classify severity categories. The climate vulnerability index (CVI) is a composite index that uses various indicators to account for socioeconomic, livelihood, and biophysical factors to study the impact of heatwave. The heat index (HI) is a measure of how hot it feels to the human body, taking into account both temperature and humidity. To assess India's climate vulnerability and the potential impact of climate change on SDG progress, researchers at the University of Cambridge conducted an analytical evaluation of the country's heat index with its climate vulnerability index. Thirteen people died from heatstroke at a Maharashtra government award function in Navi Mumbai on Sunday, making it one of the highest death tolls from a single heatwave-related event in the country's history.Īlso read | 19 districts reel under heatwave, Patna school hours revised again The paper published in 2021 said there were 706 heatwave incidents in the country from 1971-2019.
Heatwaves claimed more than 17,000 lives in 50 years in India, according to a paper authored by M Rajeevan, former secretary of Ministry of Earth Sciences, along with scientists Kamaljit Ray, S S Ray, R K Giri and A P Dimri.

The study, conducted by Ramit Debnath and colleagues at the University of Cambridge, also revealed that Delhi is particularly vulnerable to severe heatwave impacts, though its recent state action plan for climate change does not reflect this. Above-normal heatwave days are expected in most parts of central, east, and northwest India during this period.(PTI) Heatwaves in India are becoming more frequent and severe due to climate change, with over 90 percent of the country in the "extremely cautious" or "danger zone" of their impacts, according to a new study.
