ScienceDaily points to new research saying ‘We suggest the Moon as a necessary ingredient to sustain the Earth’s magnetic field’.

They believe ‘The Earth continuously receives 3,700 billion watts of power through the transfer of the gravitational and rotational energy of the Earth-Moon-Sun system’.

The Earth’s magnetic field permanently protects us from the charged particles and radiation that originate in the Sun.

Bluestone Horseshoe at Stonehenge - 19 Stones

Bluestone Horseshoe at Stonehenge – 19 Stones

Stonehenge Visitors Guide – under ‘Eclipse Cycles’ – says:

‘Now, it’s widely accepted that Stonehenge was used to predict eclipses. The inner “horseshoe” of 19 stones at the very heart of Stonehenge actually acted as a long-term calculator that could predict lunar eclipses. By moving one of Stonehenge’s markers along the 30 markers of the outer circle, it’s discovered that the cycle of the moon can be predicted. Moving this marker one lunar month at a time – as opposed to one lunar day the others were moved – made it possible for them to mark when a lunar eclipse was going to occur in the typical 47-month lunar eclipse cycle. The marker would go around the circle 38 times [2 x 19] and halfway through its next circle, on the 47th full moon, a lunar eclipse would occur.’

Talkshop regular Ian Wilson features this story in his own latest blog post at Astro-Climate-Connection:

Many scientists deny that factors external to the Earth can have a significant impact upon the Earth’s climate yet there is considerable evidence that this indeed the case. Their instincts tell them that they must always look for internal factors, and internal factors alone, to explain the Earth’s climate systems. Most will admit that Moon might have some influence upon the Earth’s climate through the dissipation of its tidal forces in the Earth’s oceans but beyond that they have little time for thinking outside the box.

It is now emerging that those who reject the idea that factors external to the Earth can have a significant influence upon the Earth’s climate are increasingly at odds with the evidence.

Clues here in Earth-like atmospheric behaviours of planetary bodies, as reported by Saturn Daily. This despite the fact that Titan orbits Saturn rather than the Sun.

Scientists at UCL have observed how a widespread polar wind is driving gas from the atmosphere of Saturn’s moon Titan. The team analysed data gathered over seven years by the international Cassini probe, and found that the interactions between Titan’s atmosphere, and the solar magnetic field and radiation, create a wind of hydrocarbons and nitriles being blown away from its polar regions into space. This is very similar to the wind observed coming from the Earth’s polar regions. [bold added]


This repost of Ian Wilson’s Jan 1st article at his Astro-Climate-Connection blog continues development of his hypothesis that the Moon triggers El Nino events. This is relevant as we are currently on the cusp of El Nino, which may develop as the year goes on. Ian predicted El Nino for later this year in a comment here last year, based on his investigations.

The El Niños during New Moon Epoch 5 – 1963 to 1994
Jan 1st 2015 : Ian Wilson PhD

A detailed investigation of the precise alignments between the lunar synodic [lunar phase] cycle and the 31/62 year Perigee-Syzygy cycle between 1865 and 2014 shows that it naturally breaks up into six 31 year epochs each of which has a distinctly different tidal property. The second 31 year interval starts with the precise alignment on the 15th of April 1870 with the subsequent epoch boundaries occurring every 31 years after that:

Epoch 1 – Prior to 15th April  1870
Epoch 2 – 15th April 1870 to 18th April 1901
Epoch 3 – 8th April 1901 to 20th April 1932
Epoch 4 – 20th April 1932 to 23rd April 1963
Epoch 5 – 23rd April 1963 to 25th April 1994
Epoch 6 – 25th April 1994 to 27th April 2025
The hypothesis that the 31/62 year seasonal tidal cycle plays a significant role in sequencing the triggering of El Niño events leads one to reasonably expect that tidal effects for the following three epochs:
New Moon Epoch:
Epoch 1 – Prior to 15th April  1870
Epoch 3 – 8th April 1901 to 20th April 1932
Epoch 5 – 23rd April 1963 to 25th April 1994

Reblogged from Ishtar’s Gate, a blog covering diverse subjects relating to antiquity, myth, culture, legend and ancient arts. Although the idea that the Aubrey holes around the outside of the stone complex have an astronomical observation and eclipse prediction purpose has been dismissed because later cremations were found in them, their number, spacing and mathematical relationship to the station stones indicates otherwise. Ishtar’s introduction follows:

This is from the book of the same title by the highly regarded Robin Heath, and it is a deeply researched and expert interpretation of the sacred geometrical azimuths and alignments of Stonehenge.

It is well established that the axis of Stonehenge aligns approximately to the midsummer rising sun azimuth. In addition, the station stone rectangle is constructed perpendicular to the axis and has a ratio of 5:12. In Megalithic yards, this is 40:96, i.e. the units of the rectangle’s ratio are expressed in 8 MY ‘quanta’.



Two long-term models of lunar cycles

Lunar chart 1

Lunar chart 1

The idea here is to link up different lunar periods in a schematic intended to show how they integrate into a ‘bigger picture’, for lack of a better phrase.

This chart of selected lunar data is based on the numbers from this blog post comment:

The top line of the chart contains original data. The rest shows the differences between the original figures (e.g. 2079 – 1973 = 106) in a structured format. By using periods where there’s a good match with whole numbers, the patterns of the relationships can perhaps more readily be identified in diagrammatic form.


What is a Saros? Quoting Wikipedia:
‘One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur’

‘It takes between 1226 and 1550 years for the members of a saros series to traverse the Earth’s surface from north to south (or vice-versa)’

Only a few lines to go … (more…)

The Secret Astronomer’s Other Ball
Tim Cullen April 2012

There are a series of celebrations and jamborees scheduled for the 5th and 6 June 2012 to commemorate a last in your lifetime event, lasting 6 hours and 40 minutes[1], called the Transit of Venus 2012[2].

For the children born after 8th June 2004[3] this is a once in a lifetime event because the next cyclical pair[4] of transits are scheduled for the 2117 and 2125, while the previous pair occurred during the Victorian age in 1874 and 1882.

The moon is linked to long term Atlantic changes.

For some time I’ve been wondering how the longer term cyclicities of the moon might affect the Earth’s climate.

I just came across this very interesting 2008 paper:

Lunar nodal tide effects on variability of sea level, temperature, and salinity in the Faroe-Shetland Channel and the Barents Sea
Yndestad Harald; Turrell, William R and Ozhigin, Vladimir:
Link to full paper (paywalled)


The Faroe-Shetland Channel and the Kola Section hydrographic time-series cover a time period of more than 100 years and represent two of the longest oceanographic time-series in the world. Relationships between the temperature and salinity of Atlantic water from these two areas are examined in this paper, which also presents for the first time comparisons between them and annual mean sea levels in the region. The investigation was based on a wavelet spectrum analysis used to identify the dominant cycle periods and cycle phases in all time-series. The water-property time-series show mean variability correlated to a sub-harmonic cycle of the nodal tide of about 74 years, with an advective delay between the Faroe-Shetland Channel and the Barents Sea of about 2 years. In addition, correlations better than R=0.7 were found between dominant Atlantic water temperature cycles and the 18.6-year lunar nodal tide, and better than R=0.4 for the 18.6/2=9.3-year lunar nodal phase tide. The correlation between the lunar nodal tides and the ocean temperature variability suggests that deterministic lunar nodal tides are important regional climate indicators that should be included when future regional climate variability is considered. The present analysis suggests that Atlantic water temperature and salinity fluctuations in the Nordic Seas are influenced by forced tidal mixing modulated by harmonics of the nodal tide and influencing the water mass characteristics at some point “down stream” from the Faroe-Shetland Channel. The effects of the modulated oceanic mixing are subsequently distributed as complex coupled lunar nodal sub-harmonic spectra in the thermohaline circulation.

Lunar nodal tides against Atlantic temperature 1900-2005

Lunar nodal tides against Atlantic temperature 1900-2005 Harald Yndestad

Harald has a page on climate here:

He says:

In this analysis we may understand the forced gravitation oscillation between the earth, sun and the moon as a forced coupled oscillation system to the earth. The tide and the earth rotation responds as a non-linear coupled oscillation to the forced gravity periods from the moon and the sun. This is a complex oscillation in periods between hours and thousands of years. The forced gravitation introduces a tidal mixing in the Atlantic Ocean. This tidal mixing introduces temperature and salinity fluctuations that influences climate and the eco system.”

It looks to me like the coincidence of these lunar cycles with the planetary cycles in my previous post may go some way to explaining the peak temperatures Earth experienced recently. These longer term cycles cause tidal mixing and overturning in the ocean which will affect the absorption and release of oceanic heat energy. This will be the subject of my next post.
