We Are Not Alone

The first half of November was the coldest on record for Chicago, Illinois.  Record there go back nearly 150 years.  The coldest on record there was back in 1991, which many of you may recall because the Minnesota Twins won the World Series and the famed Halloween Blizzard occurred that year, was quite cold in North Dakota as well.  What is remarkable about Chicago setting cold records is and always will be impressive because of the massive Urban Heat Island (UHI) of that city that generally keeps areas anywhere from 3-5 degrees warmer than more rural areas, meaning to set a cold record it needs to beat that record by a significant amount to offset that UHI.
