Temperatures on Earth typically range from 115 degrees Fahrenheit at the hottest to minus 100 degrees at the coolest. The Earth's approximate average temperature is 61 degrees.
The hottest ever recorded air temperature on Earth was 134 degrees, which was recorded in 1913 in Death Valley, California. The highest recorded surface temperature was higher, reaching 159 degrees in the Lut Desert of Iran in 2004. Antarctica's Volstok Station holds the record for coldest temperature, reading minus 128.6 degrees in 1983.
Temperature has been regularly recorded for less than two centuries, and meteorologists believe the Earth has seen wider temperature ranges prior to measurement. Since the late 1800s, data shows that the average temperature of Earth has increased 33.4 degrees.
