Climate change is increasingly causing deadly heat waves in India, putting the nation’s development at risk and potentially reversing progress in poverty alleviation, health, and economic growth. A study by researchers from the University of Cambridge published in the journal PLOS Climate highlights the critical impacts of heat waves on India, including power outages, increased dust and air Pollution, and accelerated glacial melt in the north.

Since 1992, over 24,000 people have lost their lives to heat waves in India. As Climate change worsens, heat waves are expected to become more frequent, intense, and lethal. By 2050, Indian heat waves could surpass the survivability limit for a healthy human resting in the shade. More than 90% of the country may fall into an extreme heat “danger” zone, significantly impacting millions of lives and livelihoods.
Extreme heat poses a threat to energy security, health, and progress in reducing inequality and poverty. The study found that by 2050, outdoor working capacity could decrease by 15 percent during daylight hours due to extreme heat, costing India between 2.8 percent and 8.7 percent of its GDP and depressing living standards. Low-income populations, particularly in rapidly urbanizing cities like New Delhi, are at the greatest risk.
Despite India’s commitment to the UN’s Sustainable Development Goals, the country may not fully understand the true threat of heat waves on its population. The authors of the study urge India to update its extreme weather assessment to include the heat index and its impact on sustainable development.
Practical applications of the study’s recommendations include building heat resilience for low-income housing and implementing heat-health packages for low-income and slum dwellers. Urban greening strategies around densely populated areas can also provide relief from urban heat island effects.
India has made progress in recent years by declaring heat waves a natural disaster and mobilizing appropriate relief resources. However, as heat waves become more recurrent and long-lasting, it’s crucial for climate experts and policymakers to reevaluate the metrics for assessing the country’s climate vulnerability. Let’s join forces and push for stronger climate action to ensure a sustainable future for India and its people. Act now by supporting organizations working on climate resilience and advocating for policy changes that protect vulnerable communities from the impacts of Climate change. Together, we can make a difference.
