Ice Box

Kathleen in Calgary notes this:

This week, in Southern Manitoba, the temperature reached a blisteringly frigid -31 degrees Celsius, or nearly -24 Fahrenheit. (Wind chill values in Winnipeg—in case you were curious and/or in need of some meteorological schadenfreude—dipped to -58 Fahrenheit.) Which is crazy, and which makes for, as Yahoo's Geekquinox blog puts it, "the coldest afternoon temperatures the area has seen in several years."

...And over the past month, Yahoo notes, REMS has been reporting daily high temperatures on Mars that range from -25 to -31 degrees Celsius. (Mars seems to be having its own cold spell: The -31 degrees Celsius temperature is the coldest daily high the rover has recorded since it landed on the planet in August 2012.)
