Which is the coldest place on earth?

The confirmed coldest temperature on Earth was recorded in Vostok, Antarctica at a brisk -89.2 degrees Celsius (183 Kelvin). There is an unconfirmed report of the temperature reaching -91 degrees Celsius (181 Kelvin); either way you look at it; you are still freezing your butt off.
The high velocity winds at the South Pole don't make enduring the cold any easier by the dedicated scientists that work there. Winds can reach a velocity of 90 m/s. These temperatures were recorded during the Antarctic winter in June and July, during the period when the sun never actually rises. Even at its balmiest, Vostok only reaches temperatures of around -25 degrees Celsius (248 Kelvin). When we are looking at temperatures that cold, the Kelvin scale helps make the picture look less bleak; no ominous negative sign out front to make you lose all hope of getting warm. Incidentally, the warmest recorded temperature at Vostok was -19 degrees Celsius (254 Kelvin).
Vostok's elevation is almost 3500 meters above sea level, and due to the density of oxygen being less towards the poles, the scientists are working at an effective height of 5000 meters above sea level.

The lowest temperature ever recorded on earth was -129F recorded in 1983 at the Russian Base Vostok in Antarctica. Antarctica, a continent owned by no one, covers the southern end of our globe. In addition to being the coldest place on earth, Anarctica is also the wettest and the driest place on earth. Over ninety eight percent of Anarctica is covered by ice. Antactica contains seventy percent of the earth's fresh water and ninety percent of the earth's ice.
