A new cold record in the Northern Hemisphere of -69.6 Celsius (-93.2 Fahrenheit) was set on December 22, 1991, in Greenland, the Danish Meteorological Institute announced Wednesday, 28 years after the fact. 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. "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 DMI said in a statement. "There have been a lot of heat records in the last decade and it's important to recognise the extremes," DMI climatologist John Cappelen told AFP. "The possibility of getting a cold record is lower and lower but I cannot say that it won't happen anymore," he added. The previous record low in the Northern Hemisphere was -67.8 Celsius, registered in Russia on two occasions, in 1892 and 1933. 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.

Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth. "The Arctic tundra is one of the coldest biomes on Earth, and it's also one of the most rapidly warming," said Logan Berner, a global change ecologist with Northern Arizona University in Flagstaff, who led the recent research. "This Arctic greening ... read more
