An important new solar paper by Prof Valentina Zharkova and co-authors S. J. Shepherd, S. I. Zharkov & E. Popova  published in ‘Nature’ has incorporated the solar-planetary theory we’ve been researching and advancing here at the talkshop over the last decade. As well as further developing her previous double dynamo theory which now accounts for the last several […]

As long time regulars at the Talkshop know, our ongoing research into the links between planetary motion and solar variation has occasionally borne fruit in unexpected ways. The ‘shorthand’ for the sum of all planetary vectors is the Sun’s motion with respect to the barycentre of the solar system. This is the path the Sun […]

The concept of Axial Tilt [aka Obliquity] is very straightforward.

Paul Vaughan has suggested we hold a discussion on bi-decadal climatic variation, which exhibits quasi-cyclic patterns in various datasets. To get the ball rolling, Paul has kindly given some time to producing some very interesting plots which he has introduced across a few recent threads. This posts puts these in one place and acts as […]

Over the last five years there’s been a revival of an old hypothesis which suggests that the motion of the planets around the Sun modulates its output, and that variation in the Sun’s output affects the Earth’s weather and in the longer term, shifts in regional and global climate. This revival has been most visible […]

My thanks to R.J. Salvador for this guest posting of his solar variation model based on planetary periods. It’s forecast is in good agreement with that made by Tim Channon back in Feb 2011 using a different technique and different data (Judith Lean’s TSI reconstruction). R.J.’s model is available to interested parties known to the […]

Big thanks to contributor ‘Scute’ whose fascinating thread on the companionship of the meteor which burst over Chelyabinsk in Russia and the large asteroid which made a close flyby of Earth around the same data has run and run to 600 comments. Now he has come up with a paper on Arxiv which provides another […]

My thanks to Lawrence Wilson, who has taken the time and trouble to continue investigating the controversy around the question of the focus of Earth’s orbit. This has an important bearing on the climate debate, as quite large swings in TSI will occur if the Earth orbits the solar system barycentre (SSB) rather than the […]

From Wikipedia A number of effects in our solar system cause the perihelions of planets to precess (rotate) around the sun. The principle cause is the presence of other planets which perturb each other’s orbit. Another (much more minor) effect is solar oblateness. Mercury deviates from the precession predicted from these Newtonian effects. This anomalous rate […]

Well, I’m almost speechless. 🙂 After another intemperate exchange of views on WUWT, Leif suddenly comes out with this after I gave him a lesson in Newtonian mechanics: tallbloke says: July 28, 2011 at 3:59 pm Leif Svalgaard says: July 28, 2011 at 3:06 pm What you should have learned by now from the various […]

Ed Fix has been back in touch about his solar activity simulation model. Ed couldn’t reveal too much last time around as the paper was pending publication in an Elsevier book. My thanks to Ed for being true to his word and returning here to the talkshop armed with a full explanation of his model […]

Reposted from http://english.pravda.ru/science/earth/15-06-2011/118207-volcanoes-0/ Mass awakening of volcanoes in the recent years has made scientists wreck their brains over the possible causes of such increased activity. Many geophysicists believe that such activity may increase because of the interaction of the Earth with other celestial bodies, such as the Sun or the giant planets Saturn and Jupiter. Even […]

After years of pooh poohing Theodor Landscheidt’s methods, work and predictions, mainstream solar physics has made an announcement of the strong possibility of a protracted solar minimum with consequences for Earth’s climate. At a workshop in New Mexico today, the AAS brought the work of Livingstone and Penn into the spotlight and said the following, […]

The signed sunspot series, barycentric solar angular momentum series, and solar distances from the solar system barycenter plotted through the Dalton Minimum (1795-1830), can be seen in Figures A1 and A2, fromhttp://semi.gurroa.cz/Astro/Periodicities_in_the_Solar_system__Draft-current.pdf: Whereas the solar angular momentum series at the start of the current solar minimum (2008) correlates very well with the solar angular momentum series […]

Richard Holle: The big picture

Posted: January 31, 2011 by tallbloke in solar system dynamics

All of the universe affects the rest of it, as all sits in a common bowl of gravitational and magnetically connected and driven mass of ions and regular atoms, that respond to the basic physics detailing the “normal rules or laws”. To think that there are voltages or ions that move without magnetic fields attached […]

First results in from analysis of the Wolff and Patrone paper. P.G. Sharrow has made a seismic analysis showing the likely area of cell overturn releasing potential energy. Top work P.G.! I will be able to plug this value in to the model I’m building with Rob Prince. PG explains: The above is my reconstruction […]

The days of Leif’ Svalgaards ‘The sun is in perfect freefall and thus feels no forces’ idealisation are numbered. In freefall it may be, but it is subject to significant differential forces, not only from tides, but from the varying angular momenta of cells within it which do not cancel out. Solar Phys (2010) 266: […]

Vukcevic sets a Christmas puzzle

Posted: December 26, 2010 by tallbloke in solar system dynamics

Vuk has made an enigmatic comment on WUWT’s Christmas holiday open thread: vukcevic says: December 25, 2010 at 9:44 am My friend Barry impressed by my graphing skills, send me some data to plot against CETs. Since it is open thread I thought the RESULT could be of interest to some but not all of the […]

‘Watts up with that’ has an important article today on LOD – solar and cosmic ray connections. http://wattsupwiththat.com/2010/10/03/length-of-day-correlated-to-cosmic-rays-and-sunspots. The evidence is getting stronger for the planetary hypothesis all the time. My very first article on this blog was also about a connection I found between LOD and the motion of the Solar equatorial plane with […]

A lot of people might visit here, see some fairly technical conversation going on, and wonder, “What’s it all about?” So I thought I’d devote a thread to explaining what we mean when we refer to ‘solar – planetary theory’. This thread is a first attempt at clearly summarizing it, and I hope a stimulating […]
