Coldest Places on Earth: Key Regions and Temperature Records
Antarctica: The Coldest Continent on Earth
Antarctica is widely recognized as the coldest, driest, and windiest continent on the planet, with almost the entire landmass covered by a thick ice sheet that can reach up to 5 kilometers deep. This ice sheet contains about 90% of the world’s fresh water and contributes to the continent’s extreme cold by reflecting most of the sun’s energy back into space, a phenomenon known as high albedo. The average temperature in the coastal regions of Antarctica is around –10°C (14°F), while the inland plateau experiences much colder conditions, with average temperatures near –55°C (–67°F) 810.
East Antarctic Plateau: The Coldest Surface Temperatures
The East Antarctic Plateau, particularly near the ice divide, holds the record for the lowest surface temperatures ever observed on Earth. Satellite thermal infrared mapping has identified small topographic basins above 3,800 meters elevation where surface snow temperatures can drop below –90°C during clear winter nights. The coldest recorded surface temperature is approximately –98°C, which corresponds to near-surface air temperatures of about –94°C. These extreme lows are caused by a combination of high elevation, clear skies, and the pooling of cold air in shallow depressions, further intensified by strong polar vortex circulation .
South Polar Plateau and Other Polar Regions
The South Polar Plateau, which includes the geographic center of Antarctica, is consistently cited as one of the coldest places on Earth. However, the actual South Pole is not the coldest spot; instead, the coldest temperatures are found in the central plateau region 17. In addition to Antarctica, other extremely cold regions include northeastern Siberia, Greenland, and parts of Canada, which have also recorded some of the lowest air temperatures on the planet .
Greenland: Record Lows in the Northern Hemisphere
Greenland’s ice sheet is another location where some of the lowest temperatures in the Northern Hemisphere have been recorded. For example, a temperature of –66°C was measured at the French central station in February 1950, with mean daily temperatures sometimes remaining below –63°C. These conditions make Greenland one of the coldest inhabited places outside Antarctica 135.
Northeastern Siberia and Canada: Cold Poles of the North
Northeastern Siberia, particularly locations like Oymyakon and Verkhoyansk, and certain regions in Canada, are also known for their extreme cold. These areas regularly experience winter temperatures that rival those of Greenland, though they do not reach the absolute minimums found in Antarctica .
Coldest Places with Plant and Animal Life
While the coldest places on Earth are largely inhospitable, some high-altitude regions, such as the Dom summit in the Swiss Alps, support limited plant and animal life despite experiencing winter minimums as low as –20.9°C. These sites represent the coldest known habitats for angiosperm plants and certain animal species, demonstrating the resilience of life in extreme cold .
Conclusion
The coldest places on Earth are primarily found in Antarctica, especially on the East Antarctic Plateau, where surface temperatures can approach –98°C. Other notable cold regions include Greenland, northeastern Siberia, and parts of Canada. While the South Pole is iconic, the true coldest spots are found in the central Antarctic plateau and specific high-elevation basins. These regions are not only scientific curiosities but also serve as important sites for climate research and understanding the limits of life on our planet 1237+3 MORE.
