From the one-two punch of tornadoes followed by blizzards, to unseasonably warm temperatures in Canada and Europe, to brushfires in coastal California and Australia, this spate of wacky late-December weather has been one for the history books. The extreme weather is being blamed, at least in part, on El Nino, a phenomenon that occurs when water temperatures rise above normal across the central and eastern Pacific Ocean near the equator.

Flooding in England, Scotland and Wales plunged parts of the U.K. underwater, particularly northern parts of England, such as York, where the River Ouse was running more than five metres above normal summertime levels. More than 500 soldiers were dispatched to Yorkshire and Lancashire to assist in rescue efforts, according to the BBC.
