The hottest accepted recorded temperature on Earth was 134 degrees in Death Valley, California, in 1934. The coldest is -128.6 degrees at Vostok Station, Antarctica. But these are “recorded” instrument data.

The vast majority of locations on the planet are without a thermometer. So until recently, we could only guess the actual hot and cold potential for our planet. But weather satellites can now measure ground temperatures by measuring the wavelength of emitted infrared radiation.

Using this method, the hottest temperature estimated is 159.3 degrees in an uninhabited spot in the Lut Desert of Iran. The coldest is -135.8 degrees on an uninhabited glacier in eastern Antarctica.

No wonder these places are uninhabited.
