The highest temperature on Earth was measured on 10 July 1913 at Greenland Ranch, Death Valley, California, USA.
On 13 September 2012, the World Meteorological Organisation disqualified the record for the highest recorded temperature, exactly 90 years after it had been established at El Azizia, Libya, with a measurement of 58°C. The official highest recorded temperature is now 56.7°C (134°F), which was measured on 10 July 1913 at Greenland Ranch, Death Valley, California, USA.
As a result of an investigation in 2012, the WMO concluded that the El Azizia record measurement could be inaccurate by as much as 7°C due to a combination of factors including the asphalt-like surface over which the measurement was taken, which is not a fair representation of the native desert soil.
