World Bank report warns of heatwaves beyond endurance in India

New Delhi: Severe heatwaves, responsible for thousands of deaths across India over the last few decades, are increasing with alarming frequency and soon the country could become one of the first places in the world to experience heatwaves that break the human survivability limit, according to a new report.

The World Bank report titled 'Climate Investment Opportunities in India's Cooling Sector' said the country is experiencing higher temperatures that arrive earlier and stay far longer. "In April 2022, India was plunged into the grip of a punishing early spring heatwave that brought the country to a standstill, with temperatures in the capital, New Delhi, topping 46 degrees Celsius (114 degrees Fahrenheit). The month of March, which witnessed extraordinary spikes in temperatures, was the hottest ever recorded", it said. The report will be released during the two-day 'India Climate and Development Partners' Meet' being organised by World Bank in partnership with the Kerala government in Thiruvananthapuram.

Predicting that the heatwave situation in India could break the human survivability limit, it said the recent heatwave supports what many climate scientists have long cautioned about with reference to rising temperatures across South Asia. "In August 2021, the sixth assessment report of the Inter-governmental Panel on Climate Change (IPCC) warned that the Indian subcontinent would suffer more frequent and intense heat waves over the coming decade.

"The G20 climate risk atlas also warned in 2021 that heat waves across India were likely to last 25 times longer by 2036-65 if carbon emissions remain high, as in the IPCC's worst-case emission scenario," the report said. It also warned that rising heat across India can jeopardise economic productivity.

"Up to 75 percent of India's workforce, or 380 million people, depend on heat-exposed labour, at times working in potentially life-threatening temperatures. ...By 2030, India may account for 34 million of the projected 80 million global job losses from heat stress associated productivity decline," the report said. It further said India showed the largest heat exposure impacts on heavy labour among South Asian countries, with more than 101 billion hours lost a year.

Analysis by global management consulting firm, McKinsey & Company shows that lost labour from rising heat and humidity could put up to 4.5 per cent of India's GDP -- approximately USD 150-250 billion -- at risk by the end of this decade.
