@IRonMaN   It's a cult.  In a typical year between 1985-2005, people in Pittsburgh, PA experienced about 7 days above 90.6ºF in a year. By 2050, people in Pittsburgh are projected to experience an average of about 41 days per year over 90.6ºF.  But you and I probably aren't going to be around by then to say, "I told you so."
