Every year, Paul McCartney earns nearly half a million dollars from his Christmas song “Wonderful Christmastime”, which many critics regard as his worst song ever.

Between the 16th and 19th centuries global temperatures were lower than normal, resulting in what is referred to as a “little ice age.” It is for this reason that many Christmas carols and songs speak to a “White Christmas.”

An artificial Christmas tree would have to be reused for more than 20 years to be “greener” than buying a fresh-cut tree annually.
