Hottest air temperatures reported on Earth

In my previous post, I questioned the validity of the hottest temperature measured on earth: the 58°C (136.4°F) reading from Al Azizia, Libya in September 1922. If, in fact, this record is not valid, then what might be the absolute maximum temperature measured on earth? I propose that the hottest reliable, undisputed temperatures yet measured on earth are the 129°F (53.9°C) readings on four different occasions in Death Valley, California.

Questions Concerning the World Record 136.4°F (58°C) at Al Aziza, Libya

One of the "sacred cows" of world weather extremes has been the widely reported "hottest temperature ever recorded on earth", a reading of 58°C (136.4°F) reported from Al Azizia, Libya on Sept. 13, 1922. I conclude that the temperature observations at Al Azizia prior to 1927 (when the site and instruments were changed) are obviously invalid. The shelter housing the thermometer was most likely over exposed and measuring heat radiating of off the black-tarred concrete of the terrace on which it was placed.
