Today Anthony Watts from wattupwiththat tossed Nicola Scafetta to the wolves. He's got an article at WUWT (archived here):
Death blow to Barycentrism: ‘On the alleged coherence between the global temperature and the sun’s movement’Posted on March 11, 2014 by Anthony Watts
People send me stuff.
Tonight I got an email that contained a link to a paper that takes on the wonky claims related to barycentrism and Earth’s climate, specifically as it relates to Nicola Scafetta’s 2010 and 2012 papers. This new paper taking on the Scafetta claims will be published in the Journal of Atmospheric and Solar-Terrestrial Physics, April 2014. The author is Sverre Holm Department of Informatics, University of Oslo, Norway.
Here's a link to it in the Journal of Atmospheric and Solar-Terrestrial Physics and, since you probably don't have access to the journal, here's the paper itself.
Anthony had better watch it. At the rate he's going he won't have any scientists to argue that the world is cooling or not heating or whatever he wants to argue. He'll have to turn to climate scientists and accept global warming. Thing is, he's tossed out climate science too, writing (my bold):
REPLY: Oh, people will still debate it I’m sure. Tallbloke and his group of cyclists will try to prop it up, but I’d say it pretty much has reached the end of credulity as a workable theory.
Some years ago I thought the theory had some merit, and I dabbled with it a bit, but then just like with CAGW, things didn’t quite add up. Now I’m quite convinced it’s junk. – Anthony
It looks as if Anthony Watts, after blogging endlessly about how despite all the changes in climate of the past few decades, he doesn't believe his eyes that this is happening:
Why doesn't Anthony just shut down his blog? What's left for him to
Anyway, about Scafetta's patterns. Remember Anthony's "as close to royalty as he'll get" idol, Christopher Monckton of Brenchley, offered to take over the pattern journal that featured Nicola Scafetta as equal top contributor (in terms of number of papers). I don't know if he did have a hand in it's "relaunch". (It's new Editor-in-Chief is Dr Sid-Ali Ouadfeul of the Algerian Petroleum Institute, IAP, Algeria and the co-editor in chief is Nils-Axel Morner, while Nicola Scafetta is on the editorial board!)
Monckton couldn't let this one pass. He is doing a bit of a dance on Anthony's blog about all this, writing lots of comments, for example (extracts):
It is not improper to look for patterns in physical observations, for they may (or may not) reveal a physical law....I do not say that these cycles – if they are more than mere coincidences – must be caused by the infinitesimal gravitational influence of the planets on the Sun. However, that the planets are capable of influencing each other gravitationally if the influence is exerted for long enough is suggested by the coplanarity of nearly all the planetary orbits....In short, both theory and observation indicate that it is not impossible for the planets to influence the Sun and, via the Sun, the Earth/Moon system. However, merely because it is not impossible, it ain’t necessarily so.
And there's more. The mad physicist must have taken a shot at Christopher :D
Lubos Motl makes the mistake of assuming that someone with no piece of paper to say he is a scientist knows nothing about science. ... And I am also well aware of the laws of gravitation. That is why I was cautious in my approach, and I did not say, as Lubos Motl seems to imagine, that there is a detectable influence on the Earth’s climate arising from the influence of the planets on the Sun. I raised a not uninteresting question about the cause of the ocean oscillations and of the apparently-associated cycles in global temperature. I often raise such questions here, not because I wish to make a point but because I want to know the answer.
While this is hypocrisy at its finest, coming from the potty peer:
Let us be gentler with one another, and not be too harsh with those who advance theories that appear incompatible with what we think we know. The stifling of intellectual enquiry that the New Religion seeks to impose is bad enough. We must not be corrupted by it. In science, an open mind is of near-infinitely greater value than an open mouth.
A lot of people have chimed in, for example:

It was pointed out countless times in the past that the lines are time-varying. Now the message suddenly sinks in? Also, I would hardly call Scafetta’s views “barycentrism”. His approach might better be described as eccentrism, as it used any and all cycles, well beyond just the traditional barycentric ones. Leveling valid criticism at Scafetta’s work would be child’s play, but at wuwt we’ve seen time and time again attacks on Scafetta from people who don’t even understand what he has done. Sensible discussion just won’t happen here.
beng says to Christopher - you're out of your league, mate:

I’m an admirer of your courage, but when arguing physics w/Motl, you’re out of your league. Read and understand his link.

Isn’t FUD wonderful? It creates so many opportunities!
I'll let dikranmarsupial have the last word, because it stands out from all the others and is a rarity at WUWT. It's a "rare as hens' teeth" sensible comment. Also because it's the last comment in the archive. He says:

RichardLH, it appears that you did not understand the point I was making. The climate responds to changes in the forcings, if TSI goes up, then global temperatures will follow; if we have more volcanos, the resulting aerosols cause a bit of global dimming and the earth cools. Increase GHGs and temperatures will rise. The basic physics of these things are rather well understood.
If you look for cycles in the data BEFORE properly controlling for these known forcings, then your model is implicitly assuming that the effects of these forcings are precisely zero. If the net effect of these changes in individual forcings happens to be correllated with some cycle that can be fitted to the data, the effects will be attributed to this cycle, rather than to the effects of changes in forcings which actually caused them.
In statistics this is called “omitted variable bias” (http://en.wikipedia.org/wiki/Omitted-variable_bias). If you don’t include the forcings in your model, you run the risk of overestimating the effect of these nebulous cycles.
