Coldest Place on Earth discovered

Small valleys near the top of Antarctica’s ice sheet reach temperatures of nearly -100 degrees Celsius.

The finding could change scientists’ understanding of just how low temperatures can get at Earth’s surface, and how it happens, according to the researchers. This is according to a new study published this week in Geophysical Research Letters.



New data showing that the coldest sites actually reach -98 degrees Celsius (-144 degrees Fahrenheit). The temperatures are observed during the southern polar night, mostly during July and August.

Ted Scambos, a senior research scientist at the National Snow and Ice Data Center at the University of Colorado Boulder and the study’s lead author, said:

“In this area, we see periods of incredibly dry air, and this allows the heat from the snow surface to radiate into space more easily.

The record of -98 degrees Celsius is about as cold as it is possible to get at Earth’s surface, according to the researchers. For the temperature to drop that low, clear skies and dry air need to persist for several days. Temperatures could drop a little lower if the conditions lasted for several weeks, but that’s extremely unlikely to happen.”
