El Azizia, Libya
On Sept. 13, 1922, El Azizia made history after a weather station there recorded the highest temperature ever directly measured on Earth: a blistering 136.4 degrees Fahrenheit. The record stood for 90 years until the World Meteorological Organization announced in 2012 that it found the 1922 numbers to be invalid.
Although El Azizia's record has been downgraded, there's little doubt that the region is capable of reclaiming it, as temperatures regularly climb over 120 degrees in the summer. In fact, recordings at the Libyan town of Ghadames have also soared to near-record levels.
