Record-breaking heatwave threatens millions of Americans across 14 states

A blistering heatwave is set to intensify across the US, with heat advisories affecting at least 113 million Americans. Air conditioner use in Texas has surpassed records as people try to stay cool, and around 27 million people are expected to experience temperatures over 110F (43C) in the coming days. The National Weather Service warns that this heatwave is one of the strongest systems of its kind ever seen in the region and is not showing signs of letting up. Hospitals are seeing an increase in heat-related admissions, and demand for power in Texas has surpassed record numbers. The heatwave is expected to persist until next week.
