Odds of Punxsutawney Phil Seeing His Shadow

With this cold weather of recent, many have been questioning when spring will come. Well, statistically, according to the world's most accurate forecaster, early spring is rare. Since 1887, Punxsutawney Phil has seen his shadow 109 times or about 79 percent of the time. He saw his shadow last year. Early spring is still quite rare, but I wonder with climate change, if he will start seeing his shadow less frequently.
