From the Hockey Schtick, via the GWPF, news of a new paper supporting the Svensmark hypothesis:

NEW PAPER CORROBORATES SOLAR-COSMIC RAY THEORY OF CLIMATE
10/04/14 The Hockey Schtick

cloudsA paper published today in Environmental Research Letters corroborates the Svensmark cosmic ray theory of climate, whereby tiny 0.1% changes in solar activity are amplified via the effect on cosmic rays and cloud formation, which in turn may control global temperatures.

The authors find cosmic ray variations due to changes over solar cycles may have as much as 10 times larger effect than previous studies have estimated. The paper also finds that a tiny 0.2C temperature increase increases the cosmic ray induced cloud condensation nuclei by around 50%, thus acting as a natural homeostatic mechanism.

lollianus-mavortiusQuintus Flavius Maesius Egnatius Lollianus signo Mavortius (fl. 330 – 356) was a politician of the Roman Empire. Known as Roman consul Lolliano Mavorzio in the local dialect, an acephalous [headless] statue of Mavortius was discovered in Puteoli, then Pozzuoli (near Naples, Italy) in the C18th. He was Governor of Campania from 328 to 335, comes Orientis from 330 to 336, Proconsul of Africa from 334 to 337, Praefectus urbi of Rome in 342,Consul in 355 and Praetorian prefect of Italy for Constantius II between 355 and 356.

Being a well travelled man who had probably conversed with the scribes of   the Serapeum, had made many naked eye observations of the heavens, and taking a strong interest in the subject himself, he encouraged the senatorial writer Julius Firmicus Maternus to write an astrological essay, the Matheseos libri VIII. It is among the last extensive handbooks of a “scientific” astrology that circulated in the West before the appearance of Arabic texts in the 12th century. According to Firmicus Maternus, the system of horoscopic astrology was given early on to an Egyptian pharaoh named Nechepso and his priest Petosiris. The Hermetic texts were also put together during this period.

This is a repost of an article by Richard Merrick  published on the Tokenrock.com website. This is highly relevant to the research Stuart ‘Oldbrew’ and I have been doing to try to define the mechanism by which sufficient energy is being passed between planets and the Sun to account for the observations we have been making in our Why Phi? series:

Harmonic Formation
By Richard Merrick

How do harmonics form?

As waves reflect and resonate inside a container or cavity, they cross one another. As they cross, they exchange energy at specific locations called ‘damping wells.’ In quantum mechanics this is explained by Landau-Zener theory (1932).

Known as Landau damping, waves that pass through one another mostly transparently, avoiding a direct collision, are called ‘avoided crossings.’ In such cases, energy is exchanged in a ‘parameter zone’ where one wave pushes against another, creating a kind of spinning well or vortex action. Like a kind of switch, energy is passed ‘adiabatically’ (without heat loss) across the damping well in a kind of torque action.

We can think of the damping well as a kind of low-pressure zone much like those in our atmosphere that create storms, hurricanes and tornados. The surrounding pressure differential causes an implosion toward the center of the low-pressure zone, forming a vortex.

wpid-PRP-Censured.jpgOver 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 here in the blogosphere, where ideas can be kicked around with less professional reputational risk, and a faster exchange and development of concepts and narratives can take place. There has also been a steady trickle of papers published in the scientific literature relevant to the theory, and these have been championed and denigrated by bloggers on both sides of the issue.

Naturally, in the overheated atmosphere of the climate debate, the second part of the idea is especially controversial, with the Intergovernmental Panel on Climate Change telling us that human emitted ‘greenhouse gases’ are the primary driver of global warming since the middle of the last century. They also say the Sun’s variation has very little effect on climate change. An IPCC author recently took exception to our special edition on the theory and got the journal we published it in axed. The first part of the idea is controversial too, as the received wisdom from most mainstream solar physicists is that the planets are too small and too far from the Sun for their motion to affect it. They are sure that the Sun runs an internal ‘dynamo’ (Babcock & Leighton) and ‘chronometer’ (Dicke) which accounts for the observations of its cyclic variations that have been made over the centuries.

H/T to Gerry Pease for alerting me to this paper from last year by Steinhilber and Beer which lays out a solar prediction from their analysis of their reconstruction of solar activity from proxy data.

Prediction of solar activity for the next 500 years
Friedhelm Steinhilber1 and Jürg Beer1
Received 18 May 2012; revised 18 February 2013; accepted 2 March 2013.

Recently, a new low-noise record of solar activity has been reconstructed for the past 9400 years by combining two 10Be records from Greenland and Antarctica with 14C fromtree rings [Steinhilber et al., 2012]. This record confirms earlier results, namely, that the Sun has varied with distinct periodicities in the past. We present a prediction of mean solar magnetic activity averaged over 22 years for the next 500 years mainly based on the spectral information derived from the solar activity record of the past. Assuming that the Sun will continue to vary with the same periodicities for the next centuries, we extract the spectral information from the past and apply it to two different methods to predict the future of solar magnetic activity.

This is a major new paper published in the March issue of prestigious journal ‘Solar Physics’ by solar-planetary theorists Ken McCracken, Jurg Beer and Friedhelm Steinhilber, which makes a newer and more extensive analysis of planetary motion in relation to the Carbon 14 and Beryllium 10 Glactic cosmic ray proxies than the 2400 yr Hallstat cycle study we looked at yesterday. The paper has been in the works a long time (submitted in July 2012), achieving final acceptance in late February this year. I can’t make the whole paper available due to copyright restrictions, but the abstract gives a clue as to the content. I’ve added one of the figures up to help convey some of the more important results. I’ve also appended the bibliography, as this isn’t part of the paper’s main text, it’s great to see Geoff Sharp and Ian Wilson getting citations. We can discuss other parts of their paper in comments. Boy is Martin Rasmussen going to look stupid in the future, by axing PRP for publishing our solar-planetary special edition.

Here we have  two fine scientists who have written an excellent and easily readable paper, well supported by the evidence they cite.

While giggling about the botched “Death blow” dealt by Anthony Watts and other members of team wassup to our solar-planetary theory yesterday, it occurred to me that the rather thin rolled-up paper they tried to bludgeon Nicola Scafetta with only considered the all too brief thermometer record. No wonder Sverre Holm found his windows too narrow to see the big picture through, as Nicola Scafetta pointed out in a comment deleted by Anthony Watts. When considering climate swings on the timescale of interest, in this case, around 60 years, we need to look at longer records.

A paper we discussed a few days ago used a paleoproxy to compare millennial scale changes in terrestrial climatic indicators with Steinhilber et al’s 2009 10Be proxy reconstruction of TSI (Total Solar Irradiance). Their work is sufficiently detailed to be able to discern sub-centennial swings in these climatic and solar indicators. Here’s panel ‘d’ of their figure 2, which I’ve annotated with vertical lines marking peaks in the curves.

Announcement on the SORCE Status page:

TSI-stpsat3Total Irradiance Monitor Status

(updated 24 Feb. 2014)

TIM daily solar measurements have resumed in a new operations mode.

The TIM, along with all other SORCE instruments, ceased collecting solar measurements after a battery cell failure on 30 July 2013. The LASP SORCE spacecraft operations team has implemented a new means of operating the instrument to acquire continued TSI measurements in the present limited-power mode. These measurements are expected to be more intermittent and of lower quality than those during the primary mission phase due to thermal and pointing issues, and this will be reflected in the time-dependent uncertainties given in the released data files.

H/T to ‘Catweazle’ for mentioning this report: nasa-sun-earth – on solar-terrestrial relations. A web summary is available here: http://science.nasa.gov/science-news/science-at-nasa/2013/08jan_sunclimate/

sun-sdoTaster from the text:

In the galactic scheme of things, the Sun is a remarkably constant star. While some stars exhibit dramatic pulsations, wildly yo-yoing in size and brightness, and sometimes even exploding, the luminosity of our own sun varies a measly 0.1% over the course of the 11-year solar cycle.

There is, however, a dawning realization among researchers that even these apparently tiny variations can have a significant effect on terrestrial climate. A new report issued by the National Research Council (NRC), “The Effects of Solar Variability on Earth’s Climate,” lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet.
