"Tech Central Station flunks PhysicsTim Lambert goes on to cite several more examples of Georgia's BS.
I wrote earlier correcting Ross McKitrick's false claim that there is no such thing as Global Temperature. Unfortunately McKitrick's claim has been adopted and spread by people ignorant of basic physics. For example, consider this review of Essex and McKitrick's book Taken by Storm at (where else?) Tech Central Station, by Paul Georgia. If you look at Georgia's biographical details, you will see that he has studied political economy and economics and there is no evidence that he ever studied physics and it certainly shows in his review.
Before I examine what Georgia wrote in his review, I'd like to give Wikipedia a plug. I thought I'd have to quote passages from basics physics texts, but Wikipedia has accurate and careful explanations that I can link to.
No Physical MeaningEssex, who studies the underlying mathematics, physics and computation of complex dynamic processes, raises some very fundamental scientific issues with regard to global warming. Take, for instance, the 'average global temperature,' which is the primary statistic offered as evidence of global warming. The problem with this statistic is that it has no physical meaning. Temperature is not a thermodynamic variable that lends itself to statistical analysis, nor does it measure a physical quantity.If you read the Wikipedia page on temperature you will discover that it does have a physical meaning and also that it is a physical quantity. And that there is the whole field of statistical mechanics based on the application of statistics to temperature. Go figure.
