How hot can it get on Earth? It is a sort of dubious honor to be the hottest place, but some place has to be the record holder. A World Meteorological Organization panel has concluded that the all-time heat record held for exactly 90 years by El Azizia in Libya is invalid because of an error in recording the temperature. The announcement follows a danger-fraught investigation during the 2011 Libyan revolution. Death Valley National Park in California, USA, now officially holds the title of the world’s hottest place – as symbolic for meteorologists as Mt. Everest is for geographers.
