...by Christopher Essex of the Financial Post, who writes:
My dark secret needs little explanation for thermodynamically minded people. For them, it is really quite simple: The Earth is not in "thermodynamic equilibrium," so there is no single temperature for the whole thing. No statistical hocus pocus can change that. However, global warming proponents and skeptics alike have been very busy averaging temperature data, unsupervised, on an industrial scale for years.
Read close and all you see is a For Dummies version of this paper by Mr. Essex and Ross McKitrick, who after Tim Ball is probably Canada's premier Climate Change Denialist.
And in the spirit of this FP article, I will rehash my earlier post on this paper entitled "Global Warming Deniers Deny Concept Of An Average Value" . Shorter version:
...the real problem with [Essex and McKitrick's] claim is that it proves too much, can in fact be employed to prove that the concept of an average anything is meaningless.
But you have to hit the link immediately above to get all the whys and wherefores. I'm feeling lazy today.
