California’s Death Valley is the world’s hottest place, according to the World Meteorological Organization.On July 10, 1913, Greenland Ranch in Death Valley recorded a surface temperature of 134 degrees Fahrenheit, the WMO wrote in an American Meteorological Society bulletin.
Randy Cerveny, WMO’s Rapporteur of Climate and Weather Extremes, told NBC News, “That record was investigated pretty thoroughly by Dr. Arnold Court, a meteorology professor from California, back in the 1940s and determined to be valid.”
According to the Associated Press, the previous record of 136.4 degrees was held in El Azizia, Libya, but an investigation found the temperature was incorrectly recorded. “Experts say the Libyan record was set after the observer broke a more reliable instrument and used a complicated and less reliable type of thermometer. They believe the temperature was off by about 5 degrees.”
