When hockey rinks in Canada need to be refrigerated to keep them cold in December, something is very wrong. It is, after all, Canada. In December. From what I’ve heard, it’s cold there. Personally, I hope never to find out how cold. Based on this article, turns out I might not!
Additionally, 2012 was the hottest year on record in the U.S., shattering the previous record (set in 1998) by a full degree. To my knowledge, a heat record has never been beaten by a full degree.
