-90C means dry ice?
If the coldest natural temperature was -89.2, wouldn't that mean that the carbon dioxide in the air would change phase into a solid, thus turning into dry ice (which happens at -78C) ? Seems kinda weird to think of the CO2 just dropping out of the air as a solid and mixing with the antarctic snow naturally... -- All the best, Nickj (t) 08:01, 14 April 2007 (UTC)
- I had the exact same question and one person suggested that this wouldn't happen due to there not being enough CO2 present in the air, but i am not convinced that it doesn't happen. Certainly a block of dry ice would not evaporate in this temperature, right?--Jrm2007 (talk) 17:56, 22 December 2008 (UTC)
Not coldest but lowest
There is no such 'thing' as coldest temperature, or for that matter fast speed etc. It certainly is low and high temperature. The temperature is an expression how warm or how cold something is, it cannot be cold or warm in it self.--Leonfv (talk) 16:45, 17 April 2010 (UTC)
I'm not sure what you mean. There may not be a highest temperature, but absolute zero IS the lowest temperature anything can be. —Preceding unsigned comment added by 66.66.230.58 (talk) 20:41, 12 December 2010 (UTC)
The article name is 'Coldest temperature ', which is semantically wrong because a temperature can not be cold, since it is a scalar unit, it can only be described quantitatively ('low', 'high', ...). —Preceding unsigned comment added by 80.133.90.10 (talk) 00:21, 15 February 2011 (UTC)
Temperature of helium achieved in 1908
The sentence "In 1908 he managed to lower the temperature to less than one degree above absolute zero, to less than −269 °C (3 Kelvin)" does not makes sense. This is saying "helium was taken to less than 1K, to less than 3K." after reading the original paper by Heike Kamerlingh Onnes, I do not believe Onnes ever cooled helium below 1K in 1908 (or even below 2.2K, as that is when helium becomes a superfluid, not discovered until 1937). —Preceding unsigned comment added by 66.66.230.58 (talk) 20:37, 12 December 2010 (UTC)
Unsubstantiated link?
The link given for the -127.2 temperature mentioned does not validate the data. Everywhere else on the web the lowest temperature recorded seems to be -89.2. Pickle i po (talk) 12:36, 10 March 2011 (UTC)Pickle_i_po
Really Outdated
The temperatures explained in this article are really out of date. I cannot point to the lowest temperature recorded, but as a reference point, the log-periodic antennas in the Allen Telescope Array operate at about 45K. It is listed as such in the wiki article, and it is not an error, as the one time I visited the ATA, the engineer that was conducting the tour indicated the cooling mechanisms can get the antennas down to 4K. Apparently that is not sustainable for long periods of time, but they can do it. Wingtipvortex (talk) 01:08, 6 April 2012 (UTC)
melting point of carbon dioxide?
In the first paragraph that doesn't allow editing by lowly particular individuals such as myself, it says "This is lower than the melting point of carbon dioxide (dry ice).". This should be changed to the sublimation point of carbon dioxide.

Negative Kelvin Temperatures
Wouldn't they be the lowest? Halfhat (talk) 20:28, 26 April 2014 (UTC)
