<P> The standard measuring conditions for temperature are in the air, 1.5 meters above the ground, and shielded from direct sunlight . According to the World Meteorological Organization (WMO), the highest confirmed temperature on Earth recorded according to these measures was 56.7 ° C (134.1 ° F) in Furnace Creek Ranch, California, located in the Death Valley desert in the United States, on July 10, 1913 . </P> <P> From 1922 until 2012, the WMO record for the highest official temperature on Earth was 57.8 ° C (136.0 ° F), registered on 13 September 1922 in' Aziziya, Libya . In January 2012, the WMO decertified the 1922 record, citing persuasive evidence that it was a faulty reading recorded in error by an inexperienced observer . Christopher C. Burt, the weather historian writing for Weather Underground who shepherded the Libya reading's 2012 disqualification, believes that the 1913 Death Valley reading is also "a myth", and is at least four or five degrees Fahrenheit too high, as do other weather historians Dr. Arnold Court and William Taylor Reid . If the 1913 record were to be decertified, the current highest recorded temperature on Earth would be 54.0 ° C (129.2 ° F), recorded both in Death Valley on 20 June 2013, and in Mitribah, Kuwait on 21 July 2016 . </P>
