American Geophysical Union's release claimed that -100 degree Celsius might be the lowest temperature that Earth can reach naturally.
Vostok, Antarctica, now holds the world record for the coldest temperature ever recorded by a land-based weather station. Weather stations can log conditions exactly as they are, but satellites can cover much greater areas around the clock.
The study took another look at temperature data that was taken between 2004 and 2016 during the Southern Hemisphere winter in the East Antarctic Plateau.
Extremely cold after that, as well as substantially listed below the previous document of minus 93 levels Celsius (minus 135 levels Fahrenheit) observed in the exact same location.
The high elevation of the East Antarctic Plateau and its proximity to the South Pole give it the coldest climate of any region on Earth, while the small dips in the Antarctic Ice Sheet is the coldest of the coldest.
The new study also found out how such cold temperatures are possible, again building on the previous 2013 research. As per the scientists, in order to reach this temperature, the sky must be clear and the light dry wind is necessary.
"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", Dr. Scambos said. Temperatures could drop a little lower if the conditions lasted for several weeks but that's extremely unlikely to happen, Scambos said.

Dry air is also key to the ultracold temperatures, the study found. (1.8 to 2.7 m) deep within the ice.
That's 144 degrees below zero on the Fahrenheit scale!
In 2013 and in the new study, researchers calibrated the same satellite measurements of surface temperatures with data collected from weather stations on Antarctica's surface.
This is because once the temperature drops below a certain point, the air cools so slowly that it can't get significantly colder before an inevitable change in weather conditions.
"There's a limit to how long the conditions persist to allow it to cool to these ultra-low temperatures, and a limit to how much heat you can actually get through the atmosphere, because water vapor has to be nearly nonexistent in order to emit heat from the surface at these temperatures", Scambos said in a statement.
That got the study authors wondering: is there a limit to how cold it can get on the plateau?
JUST HOW COLD can it get on Earth's surface?
With remote-sensing satellites, scientists have found the coldest places on Earth, just off a ridge in the East Antarctic Plateau.
The finding came as a major surprise for the team because many of these surface valleys witnessed the same ultra-low temperature despite being hundreds of kilometers apart.
Interestingly, even though the coldest sites were spread out over hundreds of kilometers, the lowest temperatures were all almost the same.
In the next year or two, scientists are expected to pile up more data by protruding ground-based devices in colder places.
