Doctors treated hundreds of victims of heatstroke at hospitals across Pakistan on Thursday after an intense heatwave sent temperatures above normal levels due to climate change, officials said. Temperatures soared as high as 49 degrees Celsius (120 degrees Fahrenheit) the previous day in Mohenjo Daro. The city, known for its archaeological sites, is in southern Sindh province, which was badly hit by climate-induced monsoon rains and devastating floods in 2022. The heatwave is forecast to continue for at least a week. Authorities have urged people to stay indoors, hydrate and avoid unnecessary travel. But laborers say they don’t have a choice because they need to work to feed their families. “Pakistan is the fifth most vulnerable country to the impact of climate change. We have witnessed above normal rains, floods,” Rubina Khursheed Alam, the prime minister´s coordinator on climate, said at a news conference in the capital, Islamabad. Barakullah Khan, a civil defense official, asked people not to place cooking gas cylinders in open areas as a safety measure. He warned those living near fields that snakes and scorpions could enter homes and storage places in search of cooler places. This month, temperatures are likely to soar to 55 C (131 F), weather forecasters said. Doctors say they treated hundreds of patients in the eastern city of Lahore, while scores of people were brought to hospitals in Hyderabad, Larkana and Jacobabad districts in the southern Sindh province. “The situation has been getting worse since yesterday, when people affected by heat started coming to hospitals in the Punjab province,” said Ghulam Farid, a senior health official. Pakistan has set up emergency response centers at hospitals to treat patients affected by the heat. The state-run ambulance service is now carrying bottled water and ice to provide emergency treatment to victims of the heat, health officials said. The United Nations children´s agency appealed for children to be protected from the heat. “UNICEF is deeply concerned about the health and safety of babies and young children as debilitating heatwave conditions take hold in several countries,” said Sanjay Wijesekera, UNICEF regional director for South Asia.
