US heatwave: A third of Americans under extreme heat advisories bbc
A "dangerous" US heatwave is forecast to intensify this weekend, with warnings issued across the south-west.
"Do not underestimate the impact of heat", the National Weather Service (NWS) warned on Saturday.
Nearly a third of Americans - about 113 million people - are under heat advisories: from Florida to California and up to Washington state.
Phoenix, Arizona, is likely to hit 110F (43C) on Saturday for the 16th day running - nearing a record.
Death Valley in California - one of the hottest places on Earth - is forecast to reach 128F (53C).
...
Last week, the global average temperature was 63F (17.23C), the highest ever recorded.
Scientists say the temperatures are being driven by climate change and the naturally occurring weather pattern known as El Niño, which happens every three to seven years and causes temperatures to rise.
The world has already warmed by about 1.1C since the industrial era began and temperatures will keep rising unless governments around the world make steep cuts to emissions.
