The Global Warming of College Football

As a Nebraska fan this is a familiar and potentially frightening theory, but is it true? I finally heard it one too many times the other day to simply take at face value so I decided to at least take a cursory look.

The idea was simple: 1) Take all the NCAA recognized national champions since 1940 (AP Poll started in ’36) from this list, 2) Look up the average yearly temperature for the school’s respective cities using Weatherbase, and 3) Average the “temperature of champions” by decade to see if it was trending one way or the other.
