The hottest temperature ever recorded on Earth was 134 degrees Fahrenheit (56.7 degrees Celsius). This record was set on July 10, 1913, at Furnace Creek Ranch in Death Valley, California. The extreme heat in this region is due to its low elevation, geological characteristics, and climatic conditions, making it one of the hottest places on the planet. While this record has been contested and there have been debates about its accuracy due to potential measurement errors, it still stands as a significant benchmark for high temperature records and showcases the extreme conditions found in desert environments.
