The ongoing extreme heat across large parts of India is primarily driven by worsening climate change caused by the massive burning of coal, oil, and gas, UN climate chief Simon Stiell said on Wednesday (May 27, 2026).

He also highlighted the severe human and economic impact of the heatwave, particularly on people living in homes without cooling facilities and those working long hours outdoors.

"These extremes drive home the importance of measures to adapt to climate impacts, globally," said Mr. Stiell, the executive secretary of the United Nations Framework Convention on Climate Change (UNFCCC), in a statement.

His remarks came as the India Meteorological Department (IMD) on Wednesday (May 27) said heatwave to severe heatwave conditions were likely to persist over central and northwest India for the next two to three days.

The soaring temperatures have also led to a record-breaking power demand across the country. Peak power demand touched 257.3 GW on May 18, 260.4 GW on May 19, 265 GW on May 20, and a record 270.8 GW on May 21.

“India has also seen record-breaking peak electricity demand in recent days. Solar and other renewable energy sources have helped in meeting day-time peaks, and India’s strong steps to ramp up solar power have been a benefit,” said Mr. Stiell.

He added that the extreme heat underscored the importance of homegrown clean energy and energy-efficiency measures, which could help provide cooling to vulnerable populations and ensure more secure and affordable electricity for homes, businesses, vital health services, and electric transport.

This extreme heat is posing a double challenge to lives and livelihoods, coming amid the current fossil fuel cost crisis and spiralling prices of imported fossil fuels worldwide due to conflict in the West Asia said Mr. Stiell.
