Global Heatwave: Millions at Risk as Dangerous Temperatures Persist

More than 100 million people, around a third of Americans, were under extreme heat advisories this weekend, with record-breaking heat expected to continue into the new week. The south-west and parts of the west were particularly hard hit, with officials warning that conditions could worsen in Arizona, California, and Nevada. Cooling centers extended their hours in some cities, and emergency rooms prepared to treat more people with heat-related illnesses. The National Weather Service urged residents to take the heat seriously and avoid time outdoors, as the heatwave has already resulted in several deaths.
