Heat health alerts have been extended across most of England as temperatures reached 35C, marking the eighth day this year at or above 34C and setting a new annual record. Health services and rail networks reported significant strain, with multiple train operators warning of disruptions and the electricity grid operator anticipating tight power margins. Emergency services advised the public to take precautions against dehydration, heat-related illness and wildfire risks. Scientists noted that rising temperatures and more frequent heatwaves are linked to human-driven climate change, with UK summers continuing to warm over recent decades.
