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.

California wildfires

A wildfire in Solimar, in southern California's Ventura County, burned more than 400 hectares of land, forced the closure of parts of two major coastal highways and caused evacuations over the weekend.

U.K. floods

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.

South American floods

Flooding in the area where the borders of Paraguay, Argentina and Uruguay meet forced nearly 150,000 people to flee their homes last week. El Nino has brought torrential rains to the area, causing levees to fail and bodies of water to overflow.
