My past entries on this show why I’ve been tracking this data. Bottom line, Prof. Houck’s prediction of 103 degrees at Jazz Fest, though not linked to a specific time period, wasn’t supported by the source he provided to back up that prediction and in the seven years since his article, Jazz Fest temperatures, on average, have been flat, with some years hotter than average and some years cooler than average. Climate change proponents will say drastic deviations from average temperatures, both above and below average, are evidence of man’s impact on global climate, and critics will say there are few periods in the historic record where climate hasn’t changed, and often changed rapidly. And because the alarmists twist any weather event, or lack of weather event, into proof of man's impact on global climate, anthropological global warming/climate change isn't disprovable, and so falls out of the realm of science and into a matter of faith.
Here’s my updated tables that include this year’s Jazz Fest average temperature; first, average Jazz Fest temperatures, 19700 to 2013:
The alarmists always say weather doesn't equal climate but they say this mainly to discount flukes like the unusually late cold front that the whole middle part of the country was experiencing this past week, and not about, say, an unusually early warm front that would have given us record highs for late April and early May, instead of record lows.
