During the winter months “Is it cold enough for you?” is a common greeting here in Wisconsin. With the official start to winter here in the Northern hemisphere less than 2 weeks away, temperatures are dropping and many of us are experiencing temperatures at or below the freezing point. As I write this blog entry, the temperature outside is a balmy –14°C (7°F), with a wind chill of –20°C (–4°F). Days like today want to make me hibernate or temporarily move to warmer climes, especially when I think about the colder temperatures that will surely follow in January and February. I was recently reminded that as cold as it is now, it could be worse. Much worse. There was a recent report of a new record low temperature in the heart of Antarctica, and I am cold just thinking about it. The temperature? –92.3°C (–136°F, 178°K).
It doesn’t matter what temperature scale you use, that’s cold: colder than your –70°C freezer and colder than dry ice (–109.3°F, –78.5°C).
