Ex U.S. Naval Observatory astronomer and long-time talkshopper Gerry Pease has sent me a link to an update of the paper he wrote with Gregory Glenn which we discussed recently. It represents some important and novel work in our field of solar-planetary theory. Of particular interest is the tight phase and magnitude coherence of solar-barycentric torque over the last two Jose cycles.

Figure 2 has a corrected scale, Figure 3 has been added, Figure 4 replaces the previous Figure 3 with an improved overlay Figure, and Figures 3-33 have been renumbered as Figures 4-34. Less than one page of important additional explanatory text has been added, but I am confident that Talkshop readers will find the added information and improved charts well worth a read.

Another round of claims and counter-claims about climate is underway as natural variation takes its course. Talk of records often relates only to the satellite era.

Global average temperatures over land have plummeted by more than 1C since the middle of this year – their biggest and steepest fall on record, reports David Rose in The Mail on Sunday. 

According to satellite data, the late 2016 temperatures are returning to the levels they were at after the 1998 El Niño. The news comes amid mounting evidence that the recent run of world record high temperatures is about to end.

Last year Ralph Ellis proposed a ‘dust theory of ice ages’ which we featured at the Talkshop. This research looks interesting in that context, and in its own right too.

Every year, trade winds over the Sahara Desert sweep up huge plumes of mineral dust, transporting hundreds of teragrams—enough to fill 10 million dump trucks—across North Africa and over the Atlantic Ocean.

This dust can be blown for thousands of kilometers and settle in places as far away as Florida and the Bahamas. The Sahara is the largest source of windblown dust to the Earth’s atmosphere.

But researchers from MIT, Yale University, and elsewhere now report that the African plume was far less dusty between 5,000 and 11,000 years ago, containing only half the amount of dust that is transported today.

Research Paper Withdrawal by the Journal Advances in Space Research  

peer-reviewQ1: As succinctly as possible, could you tell me why you chose to publish this work under a pseudonym?

A1: We adopted pseudonyms as a measure of last resort as we could not get an unbiased and fair review from scientific journals under our real names. This is explained in more details in the attached letter we sent to the chief editor of the Journal Advances in Space Research (JASR) on Sep. 17, 2015. In brief, our real names became known to the climate-science blogosphere in 2012 when a poster, which we presented at an International Climate Conference in Denver in 2011, became available online and caused broad and intense discussions. When we later tried to publish elements of this poster as separate articles in scientific journals, we discovered that journal editors and reviewers would reject our manuscripts outright after Googling our names and reading the online discussion. The rejections were oftentimes justified by the journals using criticisms outside the scope of the manuscript at hand.  On two occasions, journal editors have even refused to send our manuscripts for review after reading the blogs and realizing the broader theoretical implications of our results, although the manuscript itself did not explicitly discuss any new theory. For example, our first paper was rejected 4 times by different journals while submitted under our real names before it was finally accepted by SpringerPlus after submitting it under pseudonyms.

Dear all,

it was a pleasure to meet you at London. Some of you asked me about my paper in press about a link between astronomical, solar and climate oscillations. Here it is:

Scafetta, N., Milani, F., Antonio Bianchini, A., Ortolani, S.: On the astronomical origin of the Hallstatt oscillation found in radiocarbon and climate records throughout the Holocene. Earth-Science Reviews 162, 24–43, 2016. There is a free access to the article, and is valid for anybody until November 10, 2016 by using this link

(Permanent copy here)

The importance of the article is that it demonstrates quite clearly that the long Hallstatt oscillation (about 2318 year period), which is observed in climate and solar records is a major stable resonance of the solar system. The paper also evaluates the other major planetary stable resonances and we found all other typical oscillations found in climate and solar records such as a quasi 20-year oscillation, a quasi 60-year oscillation, the 82-97 year Gleissberg oscillation and the 159-185 year Jose oscillation (and others).


Plenty for Talkshoppers to get their teeth into here.

Climate Etc.

by Javier

The role of solar variability on climate change, despite having a very long scientific tradition, is currently downplayed as a climatic factor within the most popular hypothesis for climate change.

Our recent conference held at Conway Hall in central London was a huge success, with over a hundred attendees being treated to two days of rapid-fire 20 minute presentations and discussion sessions. The footage has now been published online by Mark Windows, and are available for you to view at your leisure.

Another video Mark has produced, introduces the circumstances around the last-minute move from UCL to Conway hall,  and also presents interviews with many of the participants.

I had a short interview with Energy Live News


This conference was made possible by the tireless efforts of Nils-Axel Morner in the face of great difficulties, and huge credit is due to him for his determination and organisational ability.

‘How predictable’ assumes some predictability of a future ‘ice-free’ Arctic in summer – debatable at least.
H/T US CLIVAR – Climate Variability and Predictability Program

The strong decline in the summer sea ice cover of the Arctic over the last decades has led many to ask when the Arctic will be ice-free for the first time.

Rather than providing yet another answer to this question, in a recent Geophysical Research Letters article by Jahn et al., they focused on determining how well the occurrence of an ice-free Arctic can be predicted, due to the inherent internal climate variability of the system.


Ah, natural variability – the curse of the fanatical warmist.
They don’t understand it and don’t want to believe it exists.
But it does, so they’ll have to put up with it.

From the Daily Caller:

Antarctica has confounded scientists, defying the dire predictions of scientists the South Pole would shrink and exacerbate sea level rise in the coming decades.

Climate models predicted Antarctic sea ice would shrink as the world warmed, and that warming would boost snowfall over the southern continent. Neither of those predictions have panned out, and now scientists say “natural variability” is overwhelming human-induced warming.

“Truth is, the science is complex, and that in most places and with most events, natural variability still plays a dominant role, and undoubtedly will continue to do so,” Chip Knappenberger, a climate scientist with the libertarian Cato Institute, told The Daily Caller News Foundation.

“This applies to goings-on in Antarctica as well as in Louisiana,” Knappenberger said, referring to the recent flooding in Louisiana activists have already blamed global warming for.

What recent studies have shown is that…

Why jetstream shifts might be linked to Arctic ice (among other factors) is not made clear, so we’re left wondering.

Scientists have discovered the cause of the recent run of miserable wet summers as they begin to unravel the mysteries of the Atlantic jet stream, reports

Researchers from the University of Sheffield and The Met Office have identified a number of possible factors that may influence the Atlantic jet stream and therefore help to predict summer climate from one year to the next.


It’s finally happening. Thanks to Herculean efforts by Niklas Morner, we are presenting a two-day conference in central London on the 8-9th September. Speakers are coming from all over the world to present their work, and it is not to be missed!


Take the 8-9th September off work and join us for this historic event. The first UK climate conference in decades which will counter the scaremongering of the IPCC with a cool, rational approach to the study of climate change, presenting alternative explanations, new data, theory and commentary. Topics include solar-planetary theory, causes of ENSO, sea ice extent, sea level, ozone depletion, volcanos, regional forecasting, journal gatekeeping and many more.

The list of contributors is long, we are packing a huge number of presentations into this two day event. Speakers include Niklas Morner, myself, Ned Nikolov and Karl Zeller,  Nicola Scafetta, Per Strandberg, Jan-Erik Solheim, and thats before lunch on day one! Piers Corbyn will be there! So will  Christopher Monckton! See the full programme and the extended abstracts in this 35 Megabyte document for full details. There are also some travel and booking details on the website.

A trifle cynical perhaps, but it shows it’s possible to claim almost anything you want about sea ice observations. Recently NASA was ‘blaming’ the geology for the contrasting polar variations. Now it’s the IPO.

The recent trend of increasing Antarctic sea ice extent — seemingly at odds with climate model projections — can largely be explained by a natural climate fluctuation, according to a new study led by the National Center for Atmospheric Research (NCAR).


Two Months ago, solar system dynamics researcher  R.J. Salvador gave us an update on the performance of his length of day (LOD) model. Based on our planetary theory, the model has performed well so far, showing aberrations from the real world data within two standard deviations on a couple of occasions, but mainly tracking the model projection very closely indeed. Here’s the latest plot.

LOD model May 1 update

Rick says:

The model is within range. Even in the correlation period there are these wobbles where the actual deviates from the model by 2 std dev. We may have to wait until the seasons change again to know if the deviation widens or closes. I will update it again in two months.

I wish all the best for Tim.

Good luck with your BREXIT campaign. 

It’s going to be fascinating watching further updates as they arrive for signs of planetary periodicity in the aberrations and/or trying to correlate them with major weather patterns which could be responsible.

There have been many studies reporting climate cycles with a frequency in the 60-year range, and another one has just arrived.

Two things to consider are the general idea of the existence of such a cycle, which has often been proposed, and the prediction that we are entering (to quote the paper abstract) the ‘declining phase’ of it .

Some other parts / regions of the country do show an extreme but this adds weight to the flicker noise (or 1/f) hypothosis for weather noise.

Reblogged this from Dr Roy Spencer’s website as he no longer accepts comments. Climate consensus mythology exposed once again.

A George Mason University survey of 4,092 members of the American Meteorological Society (AMS) on climate change attitudes in the meteorological community has just been released.

It shows fairly general acceptance of the view that climate change is happening, that it is at least partly due to humans, and that we can mitigate it somewhat by our energy policies. Fully 37% of those surveyed (including me) consider themselves “expert” in climate science.


There’s been a lot of loud rhetoric flying around about the update to the RSS satellite temperature series. What it actually amounts to is a consolidation of the satellite temperature measurement effort.


The two time series are now in good agreement and exhibit a warming rate of 0.13K/decade during the 1980-2015 period.


Ian Wilson has just blogged this post, which should be a bit of a showstopper in the climate debate, but I expect it’ll be studiously ignored by mainstream climate scientists and lukewarm climate-sceptic blogs. By doing that, they’ll make themselves and their pet CO2 paradigm increasingly irrelevant to scientific progress. Key thing to note is that our work here at the talkshop and in PRP means we can now predict these quasi-cyclic natural variations. Over to Ian.

Abreu et al. [2012] wrote:

“The parameter that best represents the role of the solar magnetic field in deflecting cosmic
rays [and hence, the overall level of solar activity] is the solar modulation potential , which can be derived from either the 10Be or the 14C production rates.”


“….spectral analysis [of the solar modulation potential over the last ~ 9400 years] identifies a number of distinct periodicities (Stuiver & Braziunas 1993), such as 88 yr (Gleissberg), 104 yr, 150 yr, 208 yr (de Vries), 506 yr, 1000 yr (Eddy), and 2200 yr (Hallstatt) [cycles]…”

The top figure in the following diagram shows the Fourier transform of the variation in the solar modulation potential time series over the last 9400 years [Abreu et al. 2012]. This figure shows that potential has distinct spectral peaks at 88 years (Gleissberg Cycle), 104 years, 133 years, 150 years, 210 years (de Vries Cycle), 232 years, 356 years and 504 years.

Below this is a second figure showing amplitude spectrum of variations in the North American temperature time series over the last ~ 7000 years. The temperature time series is obtained from tree ring data obtained from Bristle Cones on the Southern Colorado Plateau [for the details of the source of this data see: Could This Be The Climate Smoking Gun?  and Salzer and Kipfmeuller (2005). The lower figure shows clear spectral peaks at approximately 88, 106, 130, 148, 209, 232, 353 and 500 years.
