Executive Summary
India and nearby South Asian countries are facing more frequent, earlier, and more intense heatwaves that are driving health harms, labor losses, power demand spikes, and water stress. Attribution studies and meteorological data increasingly link these events to human-caused warming, while adaptation systems remain uneven and often inadequate.
Key Points
- Extreme heat in India and South Asia is recurring across multiple months, with several events reaching above 45C and some locations nearing 50C.
- Observed trends point to longer, more frequent, and more humid heatwaves, with rising nighttime temperatures adding stress after sunset.
- Attribution studies repeatedly connect recent heatwaves to human-caused climate change, with some events judged several times more likely in the current climate.
- The main impacts are health burdens, lost labor capacity, dehydration and heat illness, crop and livestock stress, and elevated mortality risk.
- Electricity systems are under pressure from rising cooling demand, with record or near-record peak demand, outages, and concerns about coal-backed load growth.
- Adaptation remains fragmented: heat action plans, cooling centers, warning systems, and mortality tracking are described as incomplete or unevenly targeted.
- Renewable energy, distributed solar, batteries, and grid upgrades appear in the material as practical responses, but heat also affects their performance and deployment.
