Warmist blogger Deep Climate has been doing some detective work and has found an extraordinary similarity between a paragraph of the Wegman Report (which demonstrated that the Hockey Stick algorithm was wrong) and a paragraph of a book written by a sceptic physicist, Donald Rapp.
Here's the Wegman section:
The average width of a tree ring is a function of many variables including the tree species, tree age, stored carbohydrates in the tree, nutrients in the soil, and climatic factors including sunlight, precipitation, temperature, wind speed, humidity, and even carbon dioxide availability in the atmosphere. Obviously there are many confounding factors so the problem is to extract the temperature signal and to distinguish the temperature signal from the noise caused by the many confounding factors.
And here's the Rapp equivalent

Obviously there are many confounding factors so the problem challenge is to extract the temperature signal and to thus distinguish the temperature signal from the noise caused by the many confounding factors.
Too similar to be accidental, I'm sure you would agree.
The Wegman Report was published in 2006, while Rapp's book appeared two years later. Now you or I would therefore assume that Dr Rapp had pinched the relevant paragraph from Professor Wegman, but in the bizarre world of climate science such simple explanations do not hold. Deep Climate concludes instead that Dr Rapp was a ghostwriter for the Wegman report.
And slowly the awful truth dawned on me. The Wegman report section was an early version of the text book chapter, not the other way around. I had just discovered a hitherto well hidden fourth author.
I'm speechless. I simply do not have the words to express how ridiculous this is. I'm not the only one either. One of Deep Climate's commenters wonders if our hero hasn't maybe got things back to front:
DC, are you sure you don’t have the plagiarism backwards? Rapp author was ripping off Wegman, rather than Wegman ripping off/collaborating with Rapp?
To which our supersleuth replies thusly:
[DC: That doesn't work. First off, Wegman has no knowledge of climate proxies at all. But suppose he or one of his co-authors wrote it. Then you have to suppose Rapp took that and extended it to three other proxies but kept the same style. And kept on going. I just can't see it. Something else is going on here ...]
If you refer back to the paragraphs quoted above, this is Paleoclimate 101 stuff - anyone who had read a few review papers on paleoclimate or the IPCC reports could have put this together. The idea that Wegman needed to get expert help to write this is simply risible. Half the commenters on ClimateAudit or RealClimate could have put that handful of sentences together.
It all smacks of a desperate attempt to try to smear Wegman, but one that is so transparent in its efforts to twist the facts to fit a preconceived conclusion that I think it will simply backfire on its author. It's just too funny.
Deep Climate has changed the title of his article and posted an apology to Rapp and Wegman.
