It is hot. Very hot. And we are only a few weeks into summer.
Nearly a third of Americans – over 113 million people – are under some form of heat advisory, the US National Weather Service said.
Across the US, temperatures are shattering decades-long record highs. In El Paso, Texas, temperatures have soared to above 37C – triple-digits Fahrenheit – for 27 consecutive days, overtaking a record last set in 1994.
