Even if so-called greenhouse gases were a climate problem, CO2 is only a very minor player compared to water vapour, and human-caused CO2 is only a small fraction of total atmospheric CO2. So what problem do we think we can solve?

Science Matters

Climate science is unsettling because past data are not fixed, but change later on.  I ran into this when I set out to update an analysis done in 2014 by Jeremy Shiers, which I discussed in a previous post reprinted at the end.  Jeremy provided a spreadsheet in his essay Murray Salby Showed CO2 Follows Temperature Now You Can Too posted in January 2014. I downloaded his spreadsheet intending to bring the analysis up to the present to see if the results hold up.  The two sources of data were:

Temperature anomalies from RSS here:  http://www.remss.com/missions/amsu

CO2 monthly levels from NOAA (Moana Loa): https://www.esrl.noaa.gov/gmd/ccgg/trends/data.html

Uploading the CO2 dataset showed that many numbers had changed (why?).

The blue line shows annual observed differences in monthly values year over year, e.g. June 2020 minus June 2019 etc.  The first 12 months (1979) provide the observed starting values from which differentials are calculated. …

We’ll look here at examples of where a 2400 year period has been identified by researchers in radiocarbon data.

S. S. Vasiliev and V. A. Dergachev: 2400-year cycle in atmospheric radiocarbon concentration

Abstract. We have carried out power spectrum, time-spectrum and bispectrum analyses of the long-term series of the radiocarbon concentrations deduced from measurements of the radiocarbon content in tree rings for the last 8000 years. Classical harmonic analysis of this time series shows a number of periods: 2400, 940, 710, 570, 500, 420, 360, 230, 210 and 190 years. A principle feature of the time series is the long period of ~ 2400 years, which is well known. The lines with periods of 710, 420 and 210 years are found to be the primary secular components of power spectrum. The complicated structure of the observed power spectrum is the result of ~ 2400-year modulation of primary secular components. The modulation induces the appearance of two side lines for every primary one, namely lines with periods of 940 and 570 years, of 500 and 360 years, and 230 and 190 years. The bi-spectral analysis shows that the parameters of carbon exchange system varied with the ~ 2400-year period during the last 8000 years. Variations of these parameters appear to be a climate effect on the rate of transfer of 14C between the atmosphere and the the ocean.

No 10 has posted a civil service job advertisement for the head of a new analytical unit, who, the job description said, will work inside Downing Street for two years, says a report in the Guardian.

“The analytical unit, known as 10 ‘data science’ or ‘10ds’ is a pseudo startup within No 10 designed to drive forward the quantitative revolution. The current plan is to establish a data engineering team, data science team, a skunkworks and an analytical deep dive unit,” it said.

This is easily shown from the 74 Jupiter-Saturn conjunctions in the period:
1 J-S = 19.865036 sidereal years = 19.865036*365.25636 days = 7255.8307
(7255.8307*74) / 365.259636 (anomalistic year) = 1469.99945 (1470)

So Earth reaches its perihelion with the Sun exactly 1470 times per 74 J-S.

Both numbers are even, so why is the Dansgaard-Oeschger event not at half the period?
The short answer is: Neptune.

Looks like game over for the Planet Nine idea. Unavoidable observational biases may be at least partly to blame.
– – –
Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system, says The Conversation (via Phys.org)

The presence of Planet Nine has been hypothesized to explain everything from the tilt of the sun’s spin axis to the apparent clustering in the orbits of small, icy asteroids beyond Neptune.

But does Planet Nine actually exist?

The Saros cycle by numbers

Posted: April 14, 2020 by oldbrew in Analysis, Cycles, data, moon


The basis for discussion is the abstract of the paper below. Instead of their ‘high-integer near commensurabilities among lunar months’ we’ll just say ‘numbers’ and try to make everything as straightforward as possible. This will expand on a previous Talkshop post on much the same topic.

Hunting for Periodic Orbits Close to that of the Moon in the Restricted Circular Three-Body Problem (1995)
Authors: G. B. Valsecchi, E. PerozziA, E. Roy, A. Steves

Abstract
The role of high-integer near commensurabilities among lunar months — like the long known Saros cycle — in the dynamics of the Moon has been examined in previous papers (Perozzi et al., 1991; Roy et al., 1991; Steves et al., 1993). A by-product of this study has been the discovery that the lunar orbit is very close to a set of 8 long-period periodic orbits of the restricted circular 3-dimensional Sun-Earth-Moon problem in which also the secular motion of the argument of perigee ω is involved (Valsecchi et al., 1993a). In each of these periodic orbits 223 synodic months are equal to 239 anomalistic and 242 nodical ones, a relationship that approximately holds in the case of the observed Saros cycle, and the various orbits differ from each other for the initial phases. Note that these integer ratios imply that, in one cycle of the periodic orbit, the argument of perigee ω makes exactly 3 revolutions, i.e. the difference between the 242 nodical and the 239 anomalistic months (these two months differ from each other just for the prograde rotation of ω).
[bold added]

To start with we can create a model that pretends the ‘high-integer near commensurabilities’ really are whole numbers, then break down the logic of the result to see what’s going in with the Moon at the period of one Saros cycle.

Accurate ENSO forecasts without salinity data only extend out 4 months, while those with it cover 7 months, researchers believe.
– – –
When modeling the El Niño-Southern Oscillation (ENSO) ocean-climate cycle, adding satellite sea surface salinity—or saltiness—data significantly improves model accuracy, according to a new NASA study.

ENSO is an irregular cycle of warm and cold climate events called El Niño and La Niña, says Phys.org.

In normal years, strong easterly trade winds blow from the Americas toward southeast Asia, but in an El Niño year, those winds are reduced and sometimes even reversed.

Warm water that was “piled up” in the western Pacific flows back toward the Americas, changing atmospheric pressure and moisture to produce droughts in Asia and more frequent storms and floods in the Americas.

The reverse pattern is called a La Niña, in which the ocean in the eastern Pacific is cooler than normal.

OCR software isn’t up to the job apparently. Let’s hope they don’t resort to data ‘adjustments’ after all the public’s efforts. Rain is a popular topic in the UK.

Scientists have been amazed at the public’s response to help digitise the UK’s old rainfall records, reports BBC News.

Handwritten numbers on documents dating back 200 years are being transferred to a spreadsheet format so that computers can analyse past weather patterns.

The volunteers blitzed their way through rain gauge data from the 1950s, 40s and 30s in just four days.

Project leader Prof Ed Hawkins had suggested the work might be a good way for people to use self-isolation time.

“It’s been incredible. I thought we might get this far after three or four weeks, not three or four days,” he told BBC News.

New laser technology delves into Earth’s history.

Earth turned faster at the end of the time of the dinosaurs than it does today, reports Phys.org, rotating 372 times a year compared to the current 365, according to a new study of fossil mollusk shells from the late Cretaceous.

This means a day lasted only 23 and a half hours, according to the new study in AGU’s journal Paleoceanography and Paleoclimatology.

The ancient mollusk, from an extinct and wildly diverse group known as rudist clams, grew fast, laying down daily growth rings. The new study used lasers to sample minute slices of shell and count the growth rings more accurately than human researchers with microscopes.

The aim here is to show how the synodic periods and orbits of these three planets align with the so-called Grand Synod, a period of about 4628 years which has 27 Uranus-Neptune conjunctions and almost 233 Jupiter-Saturn conjunctions. Its half-period is sometimes referred to as the Hallstatt cycle (2314 years +/- a variable margin).

1. U-N ‘long period’
1420 Uranus-Neptune conjunctions = 1477 Neptune orbits
(for calculations, see Footnote)
1477 – 1420 = 57
Uranus-Neptune 360 degrees return is 1420/57 U-N = 24.91228 U-N long period = 4270.119 years

2. GS : U-N ratio
Grand Synod = 27 U-N = 4627.967 years (= ~233 Jupiter-Saturn conjunctions)
27 / 24.91228 = 1.0838028
1.0838028 * 12 = 13.005633
Therefore the ratio of 4627.967:4270.119 is almost exactly 13:12 (> 99.956% true)

3. Orbital data
Turning to the orbit periods nearest to the Grand Synod:
28 Neptune = 4614.157y
55 Uranus = 4620.927y
(Data: https://ssd.jpl.nasa.gov/?planet_phys_par )

4. Factor of 12
These periods fall slightly short of the 27 U-N Grand Synod (~4628 years).
However, multiplying by 12 and adding one orbit to each, gives:
28*12,+1 (337) Neptune = 55534.67y
55*12,+1 (661) Uranus = 55535.14y
27*12 (661 – 337) U-N = 55535.61y

Now the numbers match to within a year +/- 55535 years.
Also, the period is 12 Grand Synods (12*4628 = 55536y), or 13 U-N ‘long’ periods.

5. Pluto data
Pluto’s orbit period is 247.92065 years.
55535 / 247.92065y = 224.003
So 224 Pluto orbits also equate to 12 Grand Synods.


Therefore, a U-N-P synodic chart can be created for that period of time.

6. Neptune:Pluto orbits
Neptune has one more orbit in the period than an exact 3:2 ratio with Pluto – a planetary resonance.
224 P = 112*2
337 N = 112*3, +1
113 N-P = 112, +1

7. Phi factor
Uranus and Neptune both have one more orbit than this ratio:
660:336 = (55*12):(21*16)
55/21 = Phi²
12/16 = 3/4
Therefore the U:N ratio is almost (3/4 of Phi²):1

The U-N-P chart should repeat every 12 Grand synods i.e. every 55,535 years or so.

Footnote
360 / Neptune orbit (164.79132) = 2.184581
2.184581 * U-N conjunction (171.40619) = 374.4507
374.4507 – 360 = 14.4507

Obtain nearest multiple of 360 degrees:
1420 * 14.4507 = 20519.9994
20520 / 360 = 57
1420 + 57 = 1477
1420 U-N = 1477 Neptune orbits
1420 + 1477 = 2897 Uranus orbits

This contradicts climate alarmist claims such as: Global Warming Is Messing with the Jet Stream. Whether 40 years of data is enough to establish what is ‘normal’, is another matter. The fastest jetstream on record of 231 mph has only just been set, we’re told.
– – –
Rapid Arctic warming has not led to a “wavier” jet stream around the mid-latitudes in recent decades, pioneering new research has shown.

Scientists from the University of Exeter have studied the extent to which Arctic amplification—the faster rate of warming in the Arctic compared to places farther south—has affected the fluctuation of the jet stream’s winding course over the North Hemisphere, reports Phys.org.

Recent studies have suggested the warming Arctic region has led to a “wavier” jet stream—which can lead to extreme weather conditions striking the US and Europe.

However, the new study by Dr. Russell Blackport and Professor James Screen, shows that Arctic warming does not drive a more meandering jet stream.

Instead, they believe any link is more likely to be a result of random fluctuations in the jet stream influencing Arctic temperatures, rather than the other way around.

The UK is going to lead a space mission to get an absolute measurement of the light reflected off Earth’s surface, reports BBC Science.

The information will be used to calibrate the observations of other satellites, allowing their data to be compared more easily.

Called Truths, the new spacecraft was approved for development by European Space Agency member states in November.

Proponents of the mission expect its data to help reduce the uncertainty in projections of future climate change.

The two Voyager space probes, launched in 1977, are still delivering tales of the unexpected.

The boundary region between the sun’s sphere of influence and the broader Milky Way galaxy is complicated indeed.

Humanity’s second taste of interstellar space may have raised more questions than it answered, writes Mike Wall @ Space.com.

NASA’s Voyager 2 spacecraft popped free of the heliosphere — the huge bubble of charged particles that the sun blows around itself — on Nov. 5, 2018, more than six years after the probe’s pioneering twin, Voyager 1, did the same.

The mission team has now had some time to take stock of Voyager 2’s exit, which occurred in the heliosphere’s southern hemisphere (as opposed to Voyager 1, which departed in the northern hemisphere).

In a series of five papers published online today (Nov. 4) in the journal Nature Astronomy, the researchers reported the measurements made by the probe as it entered interstellar space.

Stating the obvious, but most of the heat is in the oceans if compared to the heat in the atmosphere. Wikipedia says ‘the top 2.5 m of the ocean holds as much heat as the entire atmosphere above it.’ If improved predictions are expected, evidence of that will be needed.

University of Maryland (UMD) scientists have carried out a novel statistical analysis to determine for the first time a global picture of how the ocean helps predict the low-level atmosphere and vice versa, reports Phys.org.

They observed ubiquitous influence of the ocean on the atmosphere in the extratropics, which has been difficult to demonstrate with dynamic models of atmospheric and oceanic circulation.

Somehow this apparently innocuous non-problem has to be hyped up into a crisis of epic proportions. To help achieve this, an army of climate spin doctors is always on hand to attempt the never-ending task of blaming humans for any kind of unpleasant weather.

When American climate alarmists claim to have witnessed the effects of global warming, they must be referring to a time beyond 14 years ago, says James Taylor @ RealClear Energy.

That is because there has been no warming in the United States since at least 2005, according to updated data from the National Oceanic and Atmospheric Administration (NOAA).

In January 2005, NOAA began recording temperatures at its newly built U.S. Climate Reference Network (USCRN). USCRN includes 114 pristinely maintained temperature stations spaced relatively uniformly across the lower 48 states.

H/T Climate Change Dispatch

In which a scientific project gets dropped, or ignored, when it fails to produce the expected or hoped-for incriminating ‘climate change’ related data.

There is a striking disparity between sea-level datasets favored by climate catastrophists and actual observations, which mostly exists in their imaginations, writes Jack Weatherall for Quadrant Online.

The splendiferous east coast of Tasmania never ceases to please with all its myriad landscapes.

So it was a little discombobulating to recently pass a sign planted hard against the flow of traffic following the serpentine track that threads the coastal communities, proclaiming ‘Climate Change Is Killing the Planet’.

As it was only about eight degrees at the time, I was reasonably confident I would make my destination before something akin to the fate of the death star transpired and, thankfully, I was right.

It did, however, get me to thinking of how corrupt the science of the carbon cycle has truly become in the hyperbolic atmosphere of climate politics.

Is climate alarm propaganda worse than we thought?

PA Pundits - International

From the team at CFACT ~

Newly published data gathered by NASA’s AIRS satellite confirm the Earth is warming more slowly than has been forecast by climate activists and the United Nations Intergovernmental Panel on Climate Change (IPCC). Data gathered from 2003 through 2017 confirm temperatures remained essentially flat from 2003 through 2015, finally rising briefly as a strong El Nino formed in 2015 and lasted into 2016 (https://ggweather.com/enso/oni.htm). Even with El Nino adding an illusory warming spike at the end of the period, temperatures still rose just over 0.2 degrees during the 15-year period. That pace works out to less than 1.5 degrees of warming per century.

IPCC initial forecasts called for 0.3 degrees Celsius of warming per decade, while skeptic forecasts have tended to hover around 0.1 degrees. As temperatures warmed more slowly than IPCC predicted, IPCC reduced its forecasts to meet skeptics in the middle…
