Soaring temperatures in subcontinent, which have caused widespread suffering, would be extraordinarily rare without global heating

The heatwave scorching India and Pakistan has been made 30 times more likely by the climate crisis, according to scientists. Extreme temperatures and low rainfall since mid-March have caused widespread suffering, including deaths, crop losses, forest fires, and cuts to power and water supplies.

The study is the latest to show the already severe impacts of global heating on millions of people, even though the global average temperature has risen only 1.2C above pre-industrial levels to date. If it rises to 2C, heatwaves as intense as the current one would be expected as often as every five years in India and Pakistan, the scientists estimated.

April temperatures at unprecedented levels have led to critical water and electricity shortages

For the past few weeks, Nazeer Ahmed has been living in one of the hottest places on Earth. As a brutal heatwave has swept across India and Pakistan, his home in Turbat, in Pakistan’s Balochistan region, has been suffering through weeks of temperatures that have repeatedly hit almost 50C (122F), unprecedented for this time of year. Locals have been driven into their homes, unable to work except during the cooler night hours, and are facing critical shortages of water and power.

Ahmed fears that things are only about to get worse. It was here, in 2021, that the world’s highest temperature for May was recorded, a staggering 54C. This year, he said, feels even hotter. “Last week was insanely hot in Turbat. It did not feel like April,” he said.
