December 22, 1991 was the coldest day in Northern Hemisphere,in Greenland, with temperature as low as -69.6 Celsius (-93.2 Fahrenheit), the Danish Meteorological Institute (DMI)announced Wednesday, 28 years after the fact.

According to AFP, the temperature, recorded at a weather station outside of the usual network, was exhumed by “climate detectives” who later had it confirmed by the World Meteorological Organisation.

According to DMI statement, “The record was registered at an altitude of 3,105 metres, near the topographical summit of the icecap, at an automatic test station called Klinck.”

The lowest temperature ever recorded in the world is -89.2 Celsius, at the Vostok high altitude weather station in the Antarctic, set on July 21, 1983.

“In the last decade, there have been a lot of heat records and it’s important to recognise the extremes,” DMI climatologist John Cappelen told AFP.

He said that there was less chances of getting a cold record but “I cannot say that it won’t happen anymore.”  The previous record low in the Northern Hemisphere was -67.8 Celsius, registered in Russia on two occasions, in 1892 and 1933.
