In the early 21st century, prior recordings for the highest temperature on Earth were investigated as probable mis-readings. 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. This record was decertified by the WMO in January 2012 as persuasive evidence led to a faulty reading recorded in error by an inexperienced observer.[1] The decertification of this former record led researchers to also investigate the former and current recording made in Death Valley in 1913.[2] One of the earliest objections came in 1949 by Dr. Arnold Court, who came to the conclusion that the temperature may have been the result of a sandstorm that occurred at the time.
