Death Valley National Park in U.S. is hottest placeListen /
The all-time heat record held for 90 years by El Azzizia in Libya is invalid, according to the World Meteorological Organization (WMO).
On 13 September 1922 the temperature recorded at El Azizia, about 40 kilometres south-west of Tripoli was recorded as 134.4 degrees Fahrenheit or 58 degrees Celsius.
Professor Randall Cerveny an expert on weather and climate extremes says a WMO committee has just completed a two-year long investigation of that record.
"Our committee evaluated that particular record and found that there were numerous problems with it in terms of the equipment that they used to make that measurement, in terms of the likelihood of an inexperienced observer who made it and its comparison to other locations and to its own record after this event. So when we examined that record we concluded that it was more than likely invalid and that it was not a proper measurement and therefore it should not be considered the world's hottest temperature."
WMO says the official highest recorded surface temperature of 56.7 Degrees Centigrade or 134 Degrees Fahrenheit was measured at Greenland Ranch, also known as Death Valley in California on 10 July 1913.
