India's Nights Burn: Heatwaves Grip Nation

India is increasingly experiencing sweltering nights as a consequence of global warming and inadequate urban planning, placing millions at risk. For eight of the last ten years, pre-monsoon minimum temperatures have exceeded the long-term average, a trend the India Meteorological Department (IMD) has warned will continue this summer.

These sustained high nighttime temperatures pose a greater threat of heat exhaustion than daytime heat, especially for vulnerable populations lacking access to water and cooling. Urban areas contribute significantly through the 'urban heat island' effect, where concrete structures trap daytime heat and release it at night, leading to higher indoor temperatures.

The escalating heat has driven power demand to record highs, not only during the day but also at night. This has resulted in significant daily supply shortfalls, impacting states like Uttar Pradesh, where many households face extended power outages. The strain on distribution networks, coupled with geopolitical issues affecting fuel supplies, has exacerbated the crisis.

While daytime demand is partly met by solar expansion, evening supplies are more stressed. This situation highlights a critical infrastructure deficit, particularly for those without access to active cooling, making indoor heat a lethal concern. The challenge demands comprehensive solutions addressing both climate change and urban development.
