Jesse Farrell at the AccuWeather blog presents some interesting statistics about our unusually cool July in Ohio and the Eastern United States. While he is careful not to tie his analysis to the global warming argument and acknowledges that he is professionally neutral on the subject, the stats provide skeptics with some useful ammunition against those who want to go into panic mode. The link is well illustrated with tables and maps.
A few of the items:
1. There have been more than 3,000 record lows set this July, an unusually high number of records.
2. A map of the United States north and east of Memphis shows no place that had July temperatures above average, and one spot that appears to be near Somerset, Pennsylvania, that averaged 10° below normal (which Mr. Farrell considers to be "rare"). Most areas in Ohio showed a variance of 3-5° below normal.
3. Low temperatures for July in Ohio ranged from 47° to 59°. Supposedly, this is summer.
4. There is a beautiful map that shows the number of days above 85° this July. Only St. Louis, Washington, DC, and Roanoke VA showed more than one day that warm this month.
Back in December 2007, I expressed frustration at the difficulty we were experiencing knowing the truth about global warming. While I am not prepared to declare it a hoax, the findings above support others from Columbus meteorologist Jym Ganahl and the scientists cited in the December 2007 article, that cast doubt on the validity of assertions that temperatures are rising globally.*
* Which is not to discount areas, such as the Arctic, where rising temperatures are melting glaciers and endangering habitat for polar bears.
Update 7/27: A commenter in The Ohio Republic's Facebook mirror makes a telling point: "The establishment is one step ahead of you Harold as they have already changed their terms and now use 'global climate change' as their pretext for more taxation and regulation." More smoke and mirrors.
