What could be the highest temperature ever reliably recorded on Earth – 130F (54.4C) – may have been reached in Death Valley National Park, California.
The recording is being verified by the US National Weather Service.
It comes amid a heatwave on the US’s west coast, where temperatures are forecast to rise further this week.
The scorching conditions have led to two days of blackouts in California, after a power plant malfunctioned on Saturday.
