It has now been six years of recording the high and low, average high and low temperatures as reported by the Cleveland weather station. The deviations of each high and low from the average is calculated and recorded as a bit of data.
There were 2,192 days from Jan. 1, 2004, to Dec. 31, 2009, (2004 and 2008 were leap years). Each day the high and low deviations are recorded. Hence there are 4,384 bits of data. Only 174 of these bits were 20 degrees Fahrenheit or more, 132 of the 174 bits were 20 degrees F or more above average and 42 were 20 degrees F or more below average.
In 2009 when the 265 high deviations were summed, it came to +188 degrees F or +0.52 degrees F per day. The 365 low deviation came to +838 degrees F or +2.30 degrees F per day.
For the six year period the 2192 high deviations came to +1,605 degrees F or +0.73 degrees F per day. The 365 low deviations came to +5,600 degrees F or +2.56 degrees F per day.
Conclusion: Global warming can't be judged by what's happening today, last week, last month or even last year.
