Coldest Place on Earth - in Antarctica, of course

In summary, the East Antarctic Plateau was found to be the coldest place on Earth. This is due to the stable air and the cold sublimation temperature for carbon dioxide.

What’s the coldest spot on Earth? NASA has pinpointed it — and the nights are deadly​

https://www.yahoo.com/news/coldest-spot-earth-nasa-pinpointed-125903009.html

The National Snow and Ice Data Center concluded the East Antarctic Plateau was the coldest place in the world after analyzing 32 years of data from several satellites, NASA says. The hollows on the plateau are considered the coldest spots.

“Near a high ridge that runs from Dome Arugs to Dome Fuji, the scientists found clusters of pockets that have plummeted to record low temperatures dozens of times,” officials reported. “The lowest temperature the satellites detected - minus 136° F (minus 93.2° C), on Aug. 10, 2010.”

Scientists attribute the plateau’s dangerous temperatures to a combination of air that is “stationary for extended periods, while continuing to radiate more heat away into space.”

However, the plateau is not “the coldest permanently inhabited place on Earth,” experts say. That’s located in northeast Siberia, “where temperatures dropped to a bone-chilling 90 degrees below zero F (minus 67.8° C) in the towns of Verkhoyansk (in 1892) and Oimekon (in 1933).”

Isn't that lower than the sublimation temperature for CO2 at atmospheric pressure? (−78.5 °C)

Do they get dry ice snow on that Plateau?

Think about it....

"Carbon dioxide freezes at -78.5 degrees Celsius or -109.3 degrees Fahrenheit under atmospheric pressures. The coldest (we know) it has reached in Antarctica is about -93 degrees C. However, dry ice will not form there. This is because it has a very low abundance in the earth's atmosphere, about 0.04% by volume"

And when you add in wind chill, that's pretty cold... :oldbiggrin:
If you have any brass monkeys, better put 'em in a warm spot.

Although there is no wind at really cold temperatures, forget the reason, but its also the case in Yakutia in Siberia where temps get below -60C
 

Related to Coldest Place on Earth - in Antarctica, of course

1. What is the coldest temperature ever recorded in Antarctica?

The coldest temperature ever recorded in Antarctica was -89.2°C (-128.6°F) at the Russian Vostok Station in July 1983.

2. Why is Antarctica considered the coldest place on Earth?

Antarctica is considered the coldest place on Earth because it is the highest, driest, and windiest continent. Its high elevation and lack of humidity allow for extremely low temperatures to occur.

3. Is it possible for humans to survive in the coldest place on Earth?

Yes, it is possible for humans to survive in Antarctica, but it requires special equipment and precautions. The lowest temperature humans can survive in is around -50°C (-58°F), and even then, only for a short amount of time.

4. Does anything live in the coldest place on Earth?

Yes, there are a few species that have adapted to survive in the extreme conditions of Antarctica. These include penguins, seals, and some types of bacteria and algae.

5. How does the coldest place on Earth affect global climate?

The extreme cold in Antarctica plays a crucial role in regulating global climate. The continent's ice sheets and glaciers reflect sunlight, helping to cool the Earth's overall temperature. The cold waters surrounding Antarctica also contribute to ocean currents that distribute heat around the world.
