Reading of -69.C in 1991 from Greenland is nearly 2C colder than previous known records
The coldest temperature ever recorded in the northern hemisphere just got colder, thanks to the work of climate detectives at the World Meteorological Organization.
Searching through the WMO archives of heat records from weather stations at the top of the world, researchers found the coldest temperature reading came from an automatic weather station in Greenland in midwinter almost 30 years ago, nearly 2C (3.6F) colder than the previous known records.
