Talk:Coldest temperature recorded on Earth

From Wikipedia, the free encyclopedia

[edit] -90C means dry ice?

If the coldest natural temperature was -90C, 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)
