One memorable day July 21,1983, the handful of scientists who stayed for the Antarctic winter at the Vostok Station woke to a brisk temperature of -126.6 F.
Vostok Station, located 800 miles east of the South Pole at an altitude of 11,444 feet, normally endures a lovely -88 F temperature in July.
This cold record is the only reliable low-temperature measurement ever taken and it was presumably taken digitally since Mercury freezes at -40 F.
