Relevant to current discussions on the talkshop concerning changes in Earth’s length of day (LOD) and the effect of planetary orbital resonances on the Moon’s orbital parameters and Earth climatic variation; this is a repost from Ian Wilson’s excellent Astro-Climate-Connection website. Ian very generously opens with a hat tip to this blog, (at which he is one of the ‘collaborators’ he mentions). 

Connecting the Planetary Periodicities to Changes in the Earth’s LOD
Monday, October 14, 2013 : Ian Wilson PhD

[(*) Some of the findings in this blog post concerning the connection between the Earth’s rotation rate and the planetary configurations have also been independently discovered by Rog “Tallbloke” Tattersall and his collaborators]

A. The Connection Between Extreme Pergiean Spring Tides and Long-term Changes in the Earth’s Rotation Rate as Measured by the Rate-of-Change of its Length-of-Day (LOD). (*)

If you plot the rate of change of the Earth’s Length of Day (LOD) [with the short-term atmospheric component removed] against time [starting in 1962] you find that there is a ~ 6 year periodicity that is phase-locked with the 6 year period that it takes the lunar line-of-nodes  to re-align with the lunar line-of-apse [see the first note directly below and reference [1] for a description of the method used to determine the time rate of change of LOD].

NB: The pro-grade precession of the lunar line-of-apse once around the Earth with respect to the stars takes 8.8504 Julian years (J2000) while the retrograde precession of the lunar line-of-apse line-of-nodes once around the Earth with respect to the stars takes 18.6000 Julian years (J2000). Hence, the lunar line-of-apse and the ascending node of the lunar line-of-nodes will realign once every:

(18.6000 x 8.8504) / (18.6000 + 8.8504)  = 5.9969 Julian years

Science Daily reports on recent research by Oregon State University (H/T The Hockeyshtick):
A new study using evidence from a highly detailed ice core from West Antarctica shows a consistent link between abrupt temperature changes on Greenland and Antarctica during the last ice age, giving scientists a clearer picture of the link between climate in the northern and southern hemispheres.

Greenland climate during the last ice age was very unstable, the researchers say, characterized by a number of large, abrupt changes in mean annual temperature that each occurred within several decades. These so-called “Dansgaard-Oeschger events” took place every few thousand years during the last ice age. Temperature changes in Antarctica showed an opposite pattern, with Antarctica cooling when Greenland was warm, and vice versa.

In this study funded by the National Science Foundation and published this week in the journal Nature, the researchers discovered that the abrupt climates changes show up first in Greenland, with the response to the Antarctic climate delayed by about 200 years. The researchers documented 18 abrupt climate events during the past 68,000 years.

A Senate committee voted Tuesday to prohibit the Environmental Protection Agency (EPA) from using ‘secret science’ to back its regulations.

The vote in the Senate Environment and Public Works Committee came after the GOP-controlled House repeatedly approved the bill. It previous was stalled in the Democratic-majority Senate.

Under the measure, which President Obama has threatened to veto if the Senate passes it, the EPA would only be allowed to use scientific studies whose detailed results are posted publicly online.

It has not taken long for the left wing press to attack the investigation into the integrity of global temperature records!

The UK’s most prominent climate change denial group is launching an inquiry into the integrity of global surface temperature records.

The Global Warming Policy Foundation (GWPF), established by notable climate-change sceptic Lord Lawson, announced an international team of “eminent climatologists, physicists and statisticians” would investigate the reliability of the current data.

Professor Terence Kealey, the former vice-chancellor of the University of Buckingham, has been appointed chair of the international temperature data review project.

Professor Kealey studied medicine at Oxford University before lecturing on clinical biochemistry, which is primarily concerned with the analysis of bodily fluids, at Cambridge University. It is unclear what experience he has in the field of climate change.

The other five commissioners of the data review project: Petr Chylek, Richard McNider, Roman…

It was the scientific skeptics who bucked the ‘consensus’ and said the Earth was round.
By Richard McNider And John Christy Updated Feb. 19, 2014

In a Feb. 16 speech in Indonesia, Secretary of State John Kerry assailed climate-change skeptics as members of the “Flat Earth Society” for doubting the reality of catastrophic climate change. He said, “We should not allow a tiny minority of shoddy scientists” and “extreme ideologues to compete with scientific facts.” But who are the Flat Earthers, and who is ignoring the scientific facts?

ChristyMT_GL_102_Models

In ancient times, the notion of a flat Earth was the scientific consensus, and it was only a minority who dared question this belief. We are among today’s scientists who are skeptical about the so-called consensus on climate change. Does that make us modern-day Flat Earthers, as Mr. Kerry suggests, or are we among those who defy the prevailing wisdom to declare that the world is round?

Long-time critic of climate alarmism Christopher Booker has no doubt what the answer should be in his latest piece at the Telegraph:

When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.

Two weeks ago, under the headline “How we are being tricked by flawed data on global warming”, I wrote about Paul Homewood, who, on his Notalotofpeopleknowthat blog, had checked the published temperature graphs for three weather stations in Paraguay against the temperatures that had originally been recorded. In each instance, the actual trend of 60 years of data had been dramatically reversed, so that a cooling trend was changed to one that showed a marked warming.

First images from NASA OCO-2 satelite

Hot off the press release press, NASA tells us what I’ve been telling everyone who will listen for the last four years – large amounts of heat cannot magically descend through a marginally warming (or cooling) upper ocean to lurk in the abyss… The second law of thermodynamics doesn’t like that sort of thing.

While the upper part of the world’s oceans continue to absorb heat from global warming, ocean depths have not warmed measurably in the last decade. This image shows heat radiating from the Pacific Ocean as imaged by the NASA’s Clouds and the Earth’s Radiant Energy System instrument on the Terra satellite. (Blue regions indicate thick cloud cover.) Image Credit:  NASA

The cold waters of Earth’s deep ocean have not warmed measurably since 2005, according to a new NASA study, leaving unsolved the mystery of why global warming appears to have slowed in recent years.

Scientists at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, analyzed satellite and direct ocean temperature data from 2005 to 2013 and found the ocean abyss below 1.24 miles (1,995 meters) has not warmed measurably. Study coauthor Josh Willis of JPL said these findings do not throw suspicion on climate change itself.

“The sea level is still rising,” Willis noted. “We’re just trying to understand the nitty-gritty details.”

In the 21st century, greenhouse gases have continued to accumulate in the atmosphere, just as they did in the 20th century, but global average surface air temperatures have stopped rising in tandem with the gases. The temperature of the top half of the world’s oceans — above the 1.24-mile mark — is still climbing, but not fast enough to account for the stalled air temperatures.

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 an invitation to those interested in a focussed discussion on the topic.

The Bidecadal Oscillation

Is it caused by the solar Hale Cycle as suggested by Tim Channon or is it caused by the velocity of the sun with respect to the solar system barycenter as suggested by Nicola Scafetta?

It’s 10 years since the death of John Daly, but we forgot to mark this decadal anniversary back at the end of January. Here is the article by John Izzard originally published at Quadrant.org.au in 2009, which looks back at his life and work. If anyone has a copy of his book “The Greenhouse Trap” please let me know. Google and Amazon aren’t interested (and probably think n0-one else should be either).

John L. Daly (31 March 1943 – 29 January 2004)

Daly-picYesterday I visited John L. Daly’s tiny office where he lived on the outskirts of Launceston. It is about the size of two telephone boxes. His wife, Amy, has kept is just as it was when John died in 2004. His computer, his files, the maps on the wall — his notes, letters, photographs and dairies. She has also kept alive his web-site which he was still updating at the time of his death.

Looking at his scientific work today gives an insight into why the people at the IPCC (Intergovernmental Panel on Climate Change) and the University of East Anglia’s Climatic Research Unit were so annoyed with Daly’s work and why he was such a thorn in the side of their climate theories and research.

Prolific solar-planetary scientist and long-time talkshop friend Nicola Scafetta has a new paper published in Physica A entitled ‘Global temperatures and sunspot numbers. Are they related? Yes, but non linearly. A reply to Gil-Alana et al. (2014)’ which comments on Gil-Alana et al 2014; a paper purporting to dismiss any correlation between solar activity and terrestrial surface temperature. Nicola gently points out the limitations of their methods and patiently explains how the astronomical-solar signal can be found in the data. Here is Figure 3 to whet your appetite:

 

scafetta-2014b-fig3

Fig. 3. (A) Annually solved HadCRUT3 global surface temperature record [34] from 1850 to 2013. (B) Power spectrum density functions calculated using the MEM method (using M = N/2 = 82) and the MTM periodogram f (p) [35,36]: the calculations were made with the SSA–MTM Toolkit. Several spectral peaks (e.g.: at about 9.1, 10.4, 20 and 60 yr) are statistically significant above the 95% confidence level, and their solar, lunar and astronomical origin is explained in the literature (e.g.: Scafetta [10,32,33,25]).

Nicola also provides plots of several of the various solar and temperature related indices and techniques for representing them over a wide range of timescales which clearly demonstrate the plain fact of the close coherence between the activity of our host star which supplies all our energy, and the fluctuations of the lovely moderate temperatures we live in on the surface of our planet.

Thanks to commenter ‘psc3113′ for finding the concluding part of HC Russells’ paper on a lunar 19 year cycle in drought records, taken from The Queenslander (Brisbane, Qld. : 1866 – 1939)  Saturday 4 July 1896. At the conclusion of the article, the probably cause of the 19 year cycle identified is elucidated.

Periodicity of Good and Bad Seasons
MR. H. C. RUSSELL’S THEORY.
(Continued from last Week.)

Hurricanes Come in Droughts.
I should like it to be clearly understood that I do not mean ordinary hurricanes, which are as much parts of ordinary weather conditions in some parts of the world as our southerly winds are here. What I mean are extraordinary hurricanes, those that come at long intervals to terrify mankind by their power for destruction. These are connected with droughts, and, therefore should be discussed here. I had long since observed that the connection between the two was obvious enough sometimes, and during the past year I was reminded of it very often by the frequent reports of heavy gales met with by ships coming to this port, indicating great atmospheric energy. Then on the 3rd January, 1803, came the hurricane over the Tongan group of islands, and not one of the vessels in the harbour rode out the storm; every one of them was wrecked in the harbour before morning, and the wind was of such exceptional violence that after it was over the islands looked as if they had been bombarded.

Then I turned to storms on this coast, some of which were of terrible violence. And as I write, the 28th ‘May, we have the report of a terrible cyclone in America, by which three of the States, Missouri, Illinois, and Indiana were damaged and the city of St. Louis wrecked. and 1300 people killed by falling buildings, and damage to property caused to the extent, estimated, of twenty million dollars; another fragment of the present D drought.

A line from a GWPF report illustrates one of the many problems faced by the UN IPCC in its efforts to understand the world’s climate(s):
‘Facebook has over fifty times more lines of code than climate models.’

http://www.thegwpf.org/models-behaving-badly/

Having no way of verifying that, we’ll have to take their word for it, but it’s probably not that surprising. Facebook would be out of business if its code consistently failed to work as expected, but no such problem for climate models it seems.

On UCLA’s main website there is a ‘space missions’ page. On it there is a section for the Diviner mission, which mapped the Moon’s surface temperature. We covered it in a series of posts a while back, as it is crucial to our understanding of Earth’s climate:

divops_lroflybyDiviner: The Diviner Lunar Radiometer is one of seven instruments aboard NASA’s Lunar Reconnaissance Orbiter spacecraft, which was launched on June 18, 2009. It is the first instrument to create detailed, global maps of surface temperature over the lunar day and year. Diviner’s measurements are also used to map compositional variations, derive subsurface temperatures, assess the stability of potential polar ice deposits, and infer landing hazards such as roughness and rock abundance. Read more here.

But the links to the diviner subdomain are broken, and although references to other pages about the mission such as press releases and news articles are found by searching the UCLA site, the science has gone. OK, so websites get changed, links get broken, servers crash and don’t get rebooted for a while. So what?  Why does this matter?

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.

A 0.6-Million Year Record of Millennial-Scale Climate Variability in the Tropics†

Kelly Ann Gibson2,*, Larry C. Peterson1DOI: 10.1002/2013GL058846©2014. American Geophysical Union

Abstract

[1] A ~600-kyr long scanning X-ray fluorescence (XRF) record of redox variability from the Cariaco Basin, Venezuela, provides insight into rapid climate change in the tropics over the past five glacial-interglacial cycles. Variations in the sediment accumulation of the redox-sensitive element molybdenum (Mo) can be linked to changes in Intertropical Convergence Zone migration and reveal that millennial-scale variability is a persistent feature of tropical climate over the past 600 kyr, including during periods of interglacial warmth.

Guest Post By Doug Proctor.

What sparked my post is  Bob Tisdale’s graphs of global temperature anomalies AND a graph that split the anomalies into Northern and Southern Hemispheres. A clear example of a computational result that misleads: the Northern Hemisphere has been warming while the Southern Hemisphere has been cooling. Not global, regional.

Plot by Bob Tisdale

What does it tell us about, in this case, “global” warming when the temperatures of inland areas correlate well to cloud cover while the coast does not, with a mentioned “protection” from sea winds? It tells us the “global” (in this case the inland + coastal area) will have a temperature rise in its combined data while only the inland area did. And it also tells us that there is no “global” cause: it is the regional cloud cover and lack of cooling seawind that is responsible. Computational, yes, representational, no.

A conclusion and its implication in the summary paper was: because our scientific investigation leads us to the prediction that the Sun is headed into a protracted minimum, the warming forecast by the IPCC might not happen.

This has led to the journal being axed by the parent Publishing house Copernicus. The papers are still available at this link
