Heat, Hunger, and Survival: Why India’s Climate Cooling Summit Cannot Wait
Imagine this: a small town in Uttar Pradesh during a brutal summer. Evening falls, but the temperature refuses to dip below 40°C. The air is heavy with humidity, every breath feels like inhaling hot steam. Power lines collapse under the weight of demand, leaving homes in suffocating darkness. Children cry for water that no longer cools their bodies. By midnight, hundreds collapse. By dawn, thousands are dead. This is not science fiction. It is the opening scene of Kim Stanley Robinson’s The Ministry for the Future—and a scientifically accurate portrayal of what could happen in India if the wet-bulb temperature crosses 35°C. Beyond this point, even shade and water cannot prevent death. Survival becomes nearly impossible.
India is already moving toward this danger zone. In April and May 2026, large parts of the country experienced extreme heat, with daily maximum temperatures crossing 46°C in many places, reaching 48°C. One report found that in late April, 98 of the world’s 100 hottest cities were in India. In recent days, parts of Madhya Pradesh, Rajasthan, Uttar Pradesh, and Haryana also remained above 45°C, even as severe heatwave conditions affected northern, central, and eastern India.
But the cruelest part of heat is not always the afternoon sun. It is the night that never cools. Concrete, asphalt, and dense buildings trap heat during the day and release it slowly after sunset. The urban heat island effect turns homes into ovens. The body does not recover. Children cannot sleep. Elderly people gasp through the night. Those with diabetes, heart disease, asthma, kidney disease, and other chronic conditions face rising danger with every hour of trapped heat. The World Health Organization warns that extreme heat can worsen chronic illnesses and cause acute health emergencies, including heatstroke and kidney injury.
Now imagine this without air conditioning. HCI’s earlier article noted that almost 90% of Indian homes lack air conditioning and nearly 70% of the workforce labors outdoors. The deaths are largely hidden. A new paper, Estimating heatwave-induced excess mortality in India’s districts, published in Frontiers in Environmental Health, estimates that one day of extreme heat causes approximately 3,400 excess deaths across India, while a five-day heatwave causes nearly 30,000. The study also exposes a vast gap between official heat-death records and actual mortality. In a severe summer with repeated multi-day heatwaves across districts, the implied toll could exceed 150,000 hidden deaths.
Heat also becomes hunger. Extreme temperatures reduce crop yields, stress livestock, dry water sources, lower worker productivity, and disrupt supply chains. When harvests fail, food prices rise. When food prices rise, poor families eat less. As farming becomes increasingly difficult, many rural families are forced to migrate to cities in search of work—but there, too, relief is hard to find. They often end up in overcrowded informal settlements, tin-roof homes, or poorly ventilated rooms where urban heat is trapped through the night. If heatwaves combine with monsoon disruption, drought, or floods, food inflation can become hunger, rural distress can become forced migration, and in the most vulnerable regions, famine-like suffering. .
The coming years may be even more dangerous. NOAA reported in May 2026 that El Niño is likely to emerge soon, with an 82% chance in May–July 2026 and a 96% chance of continuing through the Northern Hemisphere winter of 2026–27. The World Meteorological Organization has warned that a moderate to potentially strong El Niño could raise global temperatures and intensify extreme weather, including heatwaves, droughts, heavy rains, and crop failures.
This is not a one-summer crisis. Heatwaves and excessively hot summers will increase in frequency and intensity as global warming continues. The IPCC has concluded that human-caused climate change has already increased heatwave frequency and intensity over most land areas, and that additional warming will further worsen them. At 2°C of warming, which some leading scientists warn may reach within the next decade, heat extremes are expected to more often reach critical tolerance thresholds for agriculture and human health. Feedback loops—melting ice, warmer oceans, drying forests, and fires—make the risks even more urgent.
This is why the India Climate Cooling Summit 2026 is so important. Scheduled for August 4, 2026, at the India Habitat Centre, New Delhi, the Summit is envisioned as a one-day high-level policy dialogue convening about 100 invited participants. Organized by the Healthy Climate Initiative, with collaboration from scientific, policy, civil society, philanthropic, media, and international partners, the Summit will focus on near-term climate risk reduction, resilience, responsible governance, and science-based approaches to managing escalating climate threats.
Mitigation and adaptation remain crucial. India and the world must cut emissions, restore ecosystems, remove carbon dioxide from the atmosphere, and build resilience. But slow mitigation and adaptation alone cannot manage the climate extremes already unfolding in the near term. Heatwaves, crop failures, glacier melt, floods, and food shocks are accelerating faster than our current systems can respond. We need comprehensive climate-risk planning that integrates rapid cooling options—locally, regionally, and globally—into existing mitigation and adaptation strategies. This means preparing not only for the long-term transition, but also for the immediate protection of lives, livelihoods, food systems, cities, and ecosystems from worsening climate extremes
The question is no longer whether the crisis is coming. It is here. Will we count the dead after every summer—or prepare now to protect the living? HCI believes India must act, prepare, and lead. The time is now.
