The Chicago Tribune reports that, in the first nine years of the 21st Century, Chicago has had the fewest hot days (90 degrees and above) since the 1930s. In the most recent nine years there have only been 162 days that hot, an average of only 18 days per year.
In other words, this has been the coolest decade in the last 70 years. Poor Al Gore is even less successful as a weather prophet than he was as a politician. The Nobel Peace Prize committee blew it again.
