    Paul,
    Thanks again for some very thought-provoking posts.
    The Heywood et al paper is obsessed with the Sahel;
    “We suggest that sporadic volcanic eruptions in the Northern Hemisphere also strongly influence
    this gradient and cause Sahelian drought. Using de-trended observations from 1900 to 2010, we show that three of the four driest Sahelian summers were preceded by substantial Northern Hemisphere volcanic eruptions”
    However, the greater concern to me is drought in the Indian subcontinent and sub-Sahara Africa – there are far more people living there and the risk consequences are greater.
    I have had first hand experience with sub-Saharan droughts and they are horrible. Dying animals, hungry and and dispirited people and economic ruin.
    The global economy is so fragile at the moment that a significant economic shock of a large natural event could have far greater economic and social knock-on effects than was the case in the past.
    I offer the following economic and social crude risk assessment on large natural events for discussion;
    1) Major earthquake in Japan; We were there recently. They are resilient but their economy is weaker now. Risk moderate and consequence moderate.
    2) Major earthquake in NW America; Risk low and consequence huge. It could tip the USA and the world into a global financial crisis.
    3) Major volcano in Iceland/N.Hemisphere; Risk moderate and consequence large. Air travel disruption in Europe and drought in Sahel and Indian subcontinent.
    4) Major volcano in SE Asia/S.Hemisphere; Risk moderate and consequence moderate. Drought in Sub-Saharan Africa and other S.Hemisphere tropical countries.
    We really should be turning our resources to predicting the probabilities and risks of these events.
    Global cooling or warming seems so petty in comparison.

    […]

    The degree of exploration needed as background for such a task is nowhere near finished. As constructive provocation I might even suggest it’s nowhere near beginning.

    There are people — of course — who will pretend they can provide meaningful probabilities, but I can guarantee you they will base their estimates on floods of false assumptions. False assumptions are a culturally-supported staple of standard practice in Statistics and Actuarial Science.

    The desire for estimates is so strong that the consumers of such estimates are gullible suckers. When desire is that strong, the ability to be sensible is lost and gambler’s instinct is the substitute. The real motivation is influencing what others think. On some kind of an instinctive level (even if it is unconscious, subconscious, or whatever), it’s about fooling other people and trying every which way to deke them out. Since a lot of people are conditioned by our societal norms to put faith in administrative-looking things (lol – so stupid), producing official-looking estimates might be a useful way to fool a lot of people …but I won’t be among them!!

    I will stick to exploration. Perhaps one day exploration will be complete and sensible modeling will become a possibility. When that day comes, my interest and focus will be (get this!!!) exploration. You’ll never see me modeling!

    I respect that others will pursue complementary activity.

    Poly, your contributions are sharp. You appear more-than-well-aware that the various campaigns (e.g. CO2 alarm, lukewarm sun-climate belief policing, etc.) are completely undermining the social context needed to support efficient exploration of real risk.

    The movements have taken on a “willing do die for” dimension, attracting aggressive risk-takers who are willing to go to any extreme. These are the types of people who will keep pushing and keep pushing and keep pushing limits and eventually of course everything they’ve worked for will break and that’s inevitable because their whole philosophy depends on NEVER losing power and authority. All regimes eventually fall. That’s natural.

    I agree with you that it’s very interesting to think about what natural (never mind anthropogenic! – I’m not talking about something generated by activists!!) regime changes look like. Of this I’m certain: NATURE will change powers and authorities. It’s unethical to be too suggestive about exactly when.

  7. oldmanK says:

    Poly is rightly concerned, but there are more volcanic threats than the ones he mentioned. This link: https://en.wikipedia.org/wiki/Decade_Volcanoes lists others of known high risk, nicely distributed in the lower latitudes. The Mediterranean region is not without its champions. The recent events in Italy are telling something.

    However volcanoes are responding to something else, and that ‘else’ -from my point of view- is conspicuous by its absence in the many studies.

    Tallbloke…

    You had a thread a while ago, about DLR (downwelling) not being able to penetrate the sea surface, and thus not being a component in oceanic warming.
    https://tallbloke.wordpress.com/2011/03/03/tallbloke-back-radiation-oceans-and-energy-exchange/

    I agree. So I thought I would create an energy flowchart that took this into account. It is presented below – and it works as well as any other heat flowchart.

    The major difference is the red double-headed arrow, which represents DLR from the troposphere hitting the ocean, not being absorbed, and being reradiated back up again. So this is an energy flux that is bouncing around in the atmosphere and not doing very much at all, in terms of surface heating (although it can heat the atmosphere or land-surface). So we have 279 wm2 of DLR that is no longer being absorbed by the oceans, which means that oceanic warming may be a more problematic process than previously thought.

    The left purple upflow is ULR resulting from SW absorption by sea, and DLR-SW absorption by land.

    The right blue downflow is DLR from the atmosphere being absorbed by land.

    The small green-turquoise arrows represent thermic and latent heat radiation. I have split them into two, to represent flows from direct SW oceanic heating (green) and from SW-DLR heating of land surfaces (turquoise).

    And contrary to Willis’ argument that the oceans would freeze if DLR was not absorbed by the oceans, the flowchart is balanced. There is NO net energy loss from the oceans in this chart. The only difference is that a large chunk of the energy (the red 279 wm2) is not taking part in the oceanic warming or cooling process – it is just bouncing around aimlessly between the oceans and troposphere.

    Cheers,
    Ralph Ellis

    DLR = Downwelling Longwave Radiation.
    ULR = Upwelling Longwave Radiation.

    Commenter mpainter said:
    Seems that everyone agrees that water is opaque to DWLWIR. The implications of this escape many. They believe that the GHE warms the oceans, which means that the atmosphere determines SST. But No. The opposite is the case: the oceans warm the atmosphere. The whole GHE is misconceived, based on the assumption that the GHE determines surface temperature, when in fact SST is determined by insolation alone.
    In the tropical ocean surface temperature (SST) is 30-31 C max, and air temperature one or two degrees less. Yet the tropics has the highest GHE, according to ghg concentration. Whither surface warming?
    The GHE is misconceived. In fact, it moderates air temperatures by reducing diurnal extremes. Compare humid tropics with dry Sahara.

    Samantha Stevenson (BA math, MA astronomy, PhD oceanography) appears to have unjustified naively-optimistic faith in models in general ….BUT she deserves credit for stratifying exploration by season and hemisphere and clearly acknowledging that models fail ENSO-volcano diagnostics:

    2016 – “El Nino Like” Hydroclimate Responses to Last Millennium Volcanic Eruptions


    […] after ‘‘Tropical’’ and ‘‘Northern’’ eruptions, even when ENSO-neutral conditions are present. This pattern results from Northern Hemisphere (NH) surface cooling, which shifts the intertropical convergence zone equatorward, intensifies the NH subtropical jet, and suppresses the Southeast Asian monsoon. El Niño events following an eruption can then intensify the ENSO-neutral hydroclimate signature, and El Niño probability is enhanced two boreal winters following all eruption types. Additionally, the eruption-year ENSO response to eruptions is hemispherically dependent: the winter following a Northern eruption tends toward El Niño, while Southern volcanoes enhance the probability of La Niña events and Tropical eruptions have a very slight cooling effect. Overall, eruption-year hydroclimate anomalies in CESM disagree with the proxy record in both Southeast Asia and North America, suggesting that model monsoon representation cannot be solely responsible. Possible explanations include issues with the model ENSO response, the spatial or temporal structure of volcanic aerosol distribution, or data uncertainties.

    She has another article in press:

  21. Paul Vaughan says:

    A key conceptual error in the paper to which I just linked:
    The authors make false assumptions trying to partition variance associated with the coupled multivariate bundle. They don’t realize the coupling. They are not aware of it. This ignorance is the root of the false methodological assumptions …of which I suspect they are not aware. I suspect they are making the assumptions implicitly and unconsciously. Re-education will likely be a piece of work …and if there’s any religious resistance (or even if there are just too many “misunderstandings”) it won’t be worth the effort.

    ESA are crashing the Rosetta orbiter on comet 67P/CG on 30th September 2016. It will take data at low altitude on the way down, transmitting in real time, then going silent immediately on crashing. Marco Parigi and I are campaigning for them to do a close flyby, escape and return in 2020 to do follow-up science. Success isn’t guaranteed but it’s risk-free and virtually cost-free. The alternative is a pristine comet strewn with man-made junk anyway. Even the very close flyby returns at least 4x the data as the crash scenario, and probably even more due to not needing to transmit it in real time at (nowadays far from the sun) low bit rates.

    Marco has captured the essence of the naivety of their approach in a blog post linked below. At the end, he links my blog post with a nuts and bolts approach calculating delta v for flyby, escape and 2020 reacquisition. It’s part 59 of “67P/Churyumov-Gerasimenko- a Single Body That’s Been Stretched.” Part 1 was blogged here on the Talkshop in December 2014.

    Eunice Foote’s Pioneering Research On CO2 And Climate Warming
    – Raymond P. Sorenson
    http://www.searchanddiscovery.com/documents/2011/70092sorenson/ndx_sorenson.pdf

    Abstract
    According to conventional wisdom John Tyndall was the first to measure the variation in absorption of radiant energy by atmospheric gases and the first to predict the impact on climate of small changes in atmospheric gas composition. Overlooked by modern researchers is the work of Eunice Foote, who, three years prior to the start of Tyndall’s laboratory research, conducted similar experiments on absorption of radiant energy by atmospheric gases, such as CO2 and water vapor. The presentation of her report at a major scientific convention in 1856 was accompanied by speculation that even modest increases in the concentration of CO2 could result in significant atmospheric warming.

    Reminder: In public on Earth a complete theory of spatiotemporal chaos does not exist.

    I’ve been acutely suspicious for years about why WUWT & CE keep running articles about TEMPORAL chaos. They keep repeating a narrative about temporal chaos that’s based on false spatiotemporal assumptions. (Search in-page for “spatio”, “spatial”, or just “spati”. Nothing.)

    This has been going on for years so they can no longer plead ignorance. It’s deception that has become a staple of the skeptic-luke conversion campaign.

    Earth’s circulatory architecture is a SHAPE-shifting filter.

    4-dimensional circulatory architecture is a developmental challenge for naive climate enthusiasts. Here’s something to consider carefully:

    2000 – The Global Monsoon as Seen through the Divergent Atmospheric Circulation

    My suggestion for modelers stubbornly ignorant of both aggregation criteria and circulatory architecture: Free yourself to take 2 steps forward by stepping back.

    It certainly raises suspicion when models TRANSPARENTLY don’t have spatial dimensions. A good inspector (not to be confused with a corrupt inspector who grins and turns a blind eye!) notices the omission of geometry and that (obviously!) raises sharp suspicion.

    I’m becoming acutely suspicious about the agenda of climate commentators who promote ignorance of the spatial dimensions…

    The train-of-thought I suspect:

    Put forth a parade of models of spatiotemporal phenomena based on temporally-global time-only methods (and consequently FALSE assumptions about circulatory architecture) to accumulate a straw man target eminently useful for converting people into belief in chaos + CO2 = climate.

    Omission of the spatial dimensions and geometry is a deliberate shepherding tool.

    They’re engineering the appearance that modelers are trying and failing, NEVER ACKNOWLEDGING that there was NEVER any chance they would succeed. They were GUARANTEED to fail by omitting geometry and spatial dimensions.

    It’s hard to believe people are actually stupid enough to fall for the act. The beneficiaries (whether accidental or intentional) of this core component of the skeptic-luke conversion campaign:

    Paul,
    Further to previous posts about the importance of the ITCZ (because it controls the rain over vast areas of the world).

    1) Previously we saw the ITCZ was influenced differently by the driver of explosive volcanism in each hemisphere.

    2) Now we see the ITCZ has a major newly found driver;
    “A major new result from this study is the importance, especially regionally, of the lower-tropospheric overturning cell that is centered about 800 mb and accounts for 20% of the mean annual cycle of the divergent wind. . . . . It is especially strong over Africa . . . It influences the Middle East and also has a seasonal signature over Australia. It also appears to be a very important component of the overturning in the tropical eastern Pacific and the Atlantic, and thus of the ITCZs in these regions.

    3) And the ENSO driver also influences ITCZ heavily;
    ” The existence of a single vertical structure function throughout the year and seasonal spatial structure functions also means that time series of these can be determined. . . . the global system does not vary coherently, but rather the regional monsoons and ENSO are in competition with one another, although those patterns evolve in time (e.g., Kumar et al. 1999). More vigorous activity in one sector is apt to create subsidence in another and help suppress activity there, as the largest scales tend to be emphasized in the Tropics”.

    My question is;
    Knowing these drivers, is there any reason why we cannot predict early and mitigate these terrible tropical droughts (and floods) in Sahel, Indian subcontinent, Australia and Sub-Saharan Africa?

    As usual, the trader in me sees potential for financial leverage here, but really that is secondary to the alleviation of vast human suffering.

  31. Paul Vaughan says:

    Poly, regarding your quote under item #3:

    That’s what I’ve meant whenever I’ve said
    “balanced multi-axial differential”.

    I think it’s foolish to try to do prediction before the exploration is finished.
    Certainly sensible prediction will never happen if no one has the patience to take careful exploration far enough.

    As/when time permits I continue exploring. (I have less and less time for that now.)

    I explore because it’s just natural. It has nothing to do with prediction. It’s like going for a hike or kayak. I don’t explore a waterway or a mountain to predict something.

    Perhaps modelers will use the clues of (everyone’s) exploration one day to do the prediction you desire.

    Balancing against US climate aggression and deception demands stability leadership at levels far above and beyond good protesting.

    The time is naturally ripe to shift the center of global stability.

    Perhaps signalling intention to be trustworthy players in a new stability constellation, today Saudi Arabia and Russia led. And China will back up solid moves supporting stability.

    When old sources of stability fail, people naturally look for alternative sources of stability.

    Global CO2 Budget for the 1990s
    At present, the partitioning of fossil-fuel CO2 uptake between
    components of the global carbon cycle is based on observations
    of atmospheric CO2 and O2 [2]. The method is based on the
    assumption that oceanic processes do not influence atmospheric
    O2 concentrations on multi-annual time scales.

    Conclusions
    The partitioning of fossil-fuel CO2 uptake between the ocean
    and the terrestial biosphere using atmospheric CO2 and O2
    measurements has to take into account oceanic outgassing of
    O2 due to global warming. We find that the oceanic carbon
    sink is underestimated by 0.3 GtC yr-1 during the 1980s and by
    0.5 GtC yr-1 during the1990s if this effect is not accounted for.
    The terrestrial carbon sink, on the other hand, is accordingly
    overestimated by the same amount.

    Bavaria faces 4 GW shortfall by 2022

    The head of Germany’s largest internationally active crude oil and natural gas producer says Bavaria is set for an energy crunch by 2022, with development of the state’s gas-fired power capability the best means of avoiding such an outcome.

    Wintershall CEO Mario Mehren told delegates at the German Energy Congress industry event on Tuesday, “In 2022 if not before, Bavaria will face difficulties with its electricity supply.”

    The environment ministry’s final version of the plan is still to be coordinated with other ministries. But critics say it had already been watered down under pressure from Sigmar Gabriel’s Ministry for Economic Affairs and Energy, which insisted on the omission of a date for the coal exit.

    The Earth’s climate system recurrent & multi-scale lagged responses: empirical law, evidence, consequent solar explanation of recent CO2 increases & preliminary analysis

    Abstract. This paper analyzes the lagged responses of the Earth’s climate system, as part of cosmic-solar-terrestrial processes. Firstly, we analyze and model the lagged responses of the Earth’s climate system, previously detected for geological and orbital scale processes, with simple non-linear functions, and we estimate a correspondent lag of ~1600-yr for the recently detected ~9500-yr scale solar recurrent patterns. Secondly, a recurrent and lagged linear influence of solar variation on volcanic activity and carbon dioxide (CO2) has been assessed for the last millennia, and extrapolated for future centuries and millennia. As a consequence we found that, on one side, the recent CO2 increase can be considered as a lagged response to solar activity, and, on the other side, the continental tropical climate signal during late Holocene can be considered as a sum of three lagged responses to solar activity, through direct, and indirect (volcanic and CO2), influences with different lags of around 40, 800 and 1600 years. Thirdly, we find more examples of this ~1600-yr lag, associated with oceanic processes throughout the Holocene, manifested in the mineral content of SE Pacific waters, and in a carbon cycle index, CO3, in the Southern Atlantic. Fourthly, we propose the global ocean circulation processes, that include the well known meridional overturning circulation, and the thermohaline circulation, as a global mechanism capable of explaining the lagged forcing (volcanic activity & CO2) and continental tropical climate responses to solar activity variations. Finally, some conclusions are provided for the lagged responses of the Earth’s climate system with their influences and consequences on present and future climate, and implications for climate modelling are preliminarily analyzed.

    2014 – Migrations and dynamics of the intertropical convergence zone

    Rainfall on Earth is most intense in the intertropical convergence zone (ITCZ), a narrow belt of clouds centred on average around six degrees north of the Equator. The mean position of the ITCZ north of the Equator arises primarily because the Atlantic Ocean transports energy northward across the Equator, rendering the Northern Hemisphere warmer than the Southern Hemisphere. On seasonal and longer timescales, the ITCZ migrates, typically towards a warming hemisphere but with exceptions, such as during El Niño events. An emerging framework links the ITCZ to the atmospheric energy balance and may account for ITCZ variations on timescales from years to geological epochs.

    2015/16 EL NIÑO DRIVEN BY PEAK SOLAR ACTIVITY, CHINESE SCIENTISTS SAY

    Date: 10/09/16 Wen-Juan Huo and Zi-Niu Xiao, Chinese Academy of Science

    Did the 2014 solar peak trigger strong 2015/16 El Niño warming?

    Wen-Juan Huo and Zi-Niu Xiao, two physicists at the Chinese Academy of Science, have publish new research suggesting that the strong 2015/16 El Niño event occurred right after the 2014 solar peak year and may be directly linked to solar activity peaks. The Chinese scientists found a significant positive correlation between sunspot numbers and the El Niño Modoki index, with a lag of two years. Moreover, El Niño Modoki events were found within 1–3 years following each solar peak year during the past 126 years, suggesting that anomalously strong solar activity during solar peak periods may be the key trigger of such El Niño events.

    oldmanK, as Tomas Milanovic has counseled us, a complete theory of spatiotemporal chaos does not yet exist. You will find a lot of deception artists pretending that temporal (i.e. spatiotemporal minus the spatial dimensions) chaos theory applies to climate. There’s not a shred of observational evidence to support that belief. Of course people are free to have whatever beliefs they want.

    There are a lot of propaganda agents who like the idea that climate = temporal (not spatiotemporal) chaos + CO2. It’s useful to them because they use it as a catch-all. They say there’s all the natural stuff and since it’s chaos no one should ever try to figure it out because that’s impossible and therefore the only thing that can be figured out is CO2. They love it. They push it hard.

    This is nothing new. There was lots of discussion of temporal chaos at Climate Etc. years ago and Tomas Milanovic tried to straighten people out and exposed the whole community as being corrupt. I began my boycott of that venue shortly thereafter.

    My suggestion is to be extremely suspicious any time you see people pushing TEMPORAL chaos and keeping it swept under the rug that a complete theory of SPATIOtemporal chaos does not yet exist (for humans on Earth).

    As for literature on TEMPORAL chaos. It’s endless. You could spend years of your life reading it. It’s VERY addictive. The activists are baiting you onto that hook so you’ll get lost and confused.

    Here’s a credibility tip to apply vigilantly:
    Every time you see a climate discussion thread on chaos, search the page for “spatial”, “spatio”, or “spati” more generally. Very close to 100% of the time climate articles on chaos are pure fraud and it only takes a few seconds to determine this and leave morons behind to argue about temporal chaos as if that helps develop a theory of spatiotemporal chaos (which it doesn’t).

    In plain simple terms: Don’t be a gullible sucker!

    I don’t take seriously at all anyone applying temporal chaos theory to climate. I regard their voluminous spin as an ABSTRACT bubble based on false assumptions. Earth’s surface wraps on itself, imposing aggregate constraints on chaos. Perhaps one day someone will develop a complete theory of SPATIOtemporal chaos. (Today it does not yet exist.)

    49 times out of 50 I skip Tim Ball articles. He’s often so worked up about the politics that he can’t keep his eye on the ball ….but today we see a notable exception:

    https://wattsupwiththat.com/2016/09/10/wind-an-important-forgotten-or-ignored-weather-variable/

    He appears to fathom clearly that climate’s not a time-only phenomenon. Let’s hope moving forward he can minimize his distraction by the politics and keep his eye on the ball ….maybe the wind education ball – or something complementary.

    I’ve started working on algebraic statement of the spatial constraints (the different types of contrasts) on temporal aggregates (blends).

    In a theory of spatiotemporal chaos, chaos can be afforded a (placeholder) role in the partitioning (and the consequences of the partitioning) but not in the aggregate!

    The partitioning accounts for no more than 20% of climate, but it’s the shiny bouncy part so it’s foremost in political and financial minds most days in climate discussion it seems.

    It seems to me there are a lot people (inefficiently and unwisely) working on the Pareto Principle Corollary rather than on the (order of magnitude more efficient) Pareto Principle. These are detail-oriented people and the appearance is that in their obsessive attention to luxurious detail they miss first order pattern. They are focused on second-order features (like the day’s ensoic choice of face-paint and hairstyle) that (comically) blind them to more important things accounting for 80% of the variance (like strong abs and heart in a more sensible attraction accounting scheme).

    Highest September temperature since 1911 as 34.4C recorded

    The UK’s hottest day of the year so far – and the warmest September day since 1911 – has been recorded in Gravesend, Kent, where it reached 34.4C (93.9F).

    The spell of warm Autumn weather is forecast to continue across parts of England until Friday…

    The highest temperature of 2016 had previously been 34.1C, which was reached on 23 August at Faversham in Kent.

    The all-time record for September of 35.6C (96.1F) was set in 1906, in Bawtry, South Yorkshire…

    Hurricane Hermine, which hit Florida in early September, pushed large kinks into the jet stream – large atmospheric waves which lock our weather patterns in place. For Spain and Portugal, that meant temperatures rising to 10C above average last week.

    A large area of high pressure centred over northern Europe has brought southerly winds, which have drawn this warm air northwards, reaching our shores today. And we have mainly clear skies across much of England, so we’re topping it up ourselves.

    We saw 31C in September in 1973, and in 1961, in Gatwick, the temperature recorded was 31.6C. It’s very doubtful that we will break the all-time record though, as a 1906 heat wave brought September temperatures of 35.6C (96.08F).

    A reply to PV. First, thank you for the warning and pointing out the pitfalls of applying any Chaos theory to climate. It is appreciated,- and looking up what Tomas Milanovic had to say was informative.

    I had something else in mind. Some basic aspects behind the “Chaos” maths look like offering a different perspective to the matter of stability of the dynamics of systems. In the old perspective formulae were the rule and we were always concerned with the areas where the formulae were proven to work by experiment. Most everything had its SOA (safe operating area). Engineering always demanded staying there – beyond was No-man’s-land. Formula extrapolation many times ran into trouble- sometimes at great cost as it would turn out.

    Hence the lure of what Chaos theory might offer. In engineering most everything is put to a test. However no one has put to test the equations of the dynamics of the Earth. We extrapolated into the future blindly. We extrapolated backwards in time equations that are stable – they have a stable attractor – when we know the Earth did not follow that attractor path. Worse, there is evidence of other separate attractor points. Those attractor points may determine whether it will be a ‘waterworld’ or snowball or something in between. We are lost with the details, sometimes of one variable or of a very short span of time, but have no idea which variable matters most or when.

    Someone may find these interesting. Brief videos on ‘Chaos’ maths on https://www.youtube.com/watch?v=aAJkLh76QnM

    oldmanK, the spatial patterns are MANY-TO-ONE.

    Look at the wet & dry energy transport illustrations to develop some intuition about the array of heating and cooling partitioning possibilities.

    We’re in the realm of aggregate proof.

    Tomas Milanovic’s most informative insights are not concentrated in articles he volunteered at CE but rather scattered around as spontaneous comments on various threads.

    People keep slipping into discussion of UNIvariate TEMPORAL (TIME-ONLY) chaos. The bottom line is this: A complete theory of MULTIvariate SPATIOtemporal chaos DOES NOT YET EXIST (in public at least for humans on Earth).

    Indeed there are attractors. I’ve isolated some of them empirically (as I hope you are aware) and I’ve explored algebraic expression of some of the aggregate constraints. Throwing around blizzards of algebra isn’t one of my passions so I will not allow myself to become consumed by the task of developing a theory of MULTIvariate SPATIOtemporal chaos.

    As always I’ll stick to exploration (we need an efficient division of labor) and remind anyone contemplating theory that the context is NOT UNIvariate TEMPORAL chaos, but rather MULTIvariate SPATIOtemporal chaos.

    Chaos, yes (multivariate spatiotemporal chaos to be more precise) …but as I’ve said before it’s in a box. The box accounts for 80% of the variance …and technically multivariate spatiotemporal chaos is just a placeholder for the 20% leftovers.

    Boycotting exploration of the leftovers doesn’t change the box.

    I’ve given one of the aggregate proofs algebraically. Regarding the multi-axial spatiotemporal variance partitioning about the attractors, as I have advised countless times: the empirical attractor indicates BOTH SPATIAL AND LATENT axes on the balanced multi-axial differential.

    A Hiatus of the Greenhouse Effect
    Jinjie Song, Yuan Wang & Jianping Tang
    Published online: 12 September 2016

    http://www.nature.com/articles/srep33315

    Introduction

    The rate at which the global average surface air temperature (Ts) increases has slowed down during the past few decades. This so-called hiatus, pause, or slowdown of global warming has inspired investigations into its potential causes worldwide. Although some researchers doubted the existence of a global warming hiatus because of coverage bias artificial inconsistency, and a change point analysis of instrumental Ts records, it is now accepted that a recent warming deceleration can be clearly observed. There are two primary hypotheses to explain the recent slowdown of the upward trend in Ts. Both hypotheses attempt to explain the contradiction between the trendless Ts variation and the intensifying anthropogenic greenhouse effect resulting from the steadily increasing emission of greenhouse gases (GHGs). The first attributes the warming hiatus to external radiative forcings, such as decreasing solar irradiance, increasing tropospheric and stratospheric aerosols, reduced stratospheric water vapor, and several small volcanic eruptions. The warming effect of increasing GHGs is largely cancelled out by the decreasing solar shortwave radiation received by the Earth’s surface. The second considers the warming pause to be a result of internal oceanic and/or atmospheric decadal variabilities against the centennial warming trend, in which two leading theories are proposed. One asserts that the recent warming hiatus likely results from a La Niña-like state or a negative phase of Interdecadal Pacific Oscillation (IPO) associated with the cooling tropical Pacific sea surface temperature (SST) and the increasing Pacific trade winds. This theory is supported by the successful simulation of the warming hiatus by nudging the tropical pacific SST or trade winds relative to observations. The other suggests that the warming hiatus is accompanied by increasing heat uptake in global deep oceans. This extra heat, which originates from a positive radiative imbalance at the top of the atmosphere (TOA), is reserved in the deep oceans instead of warming the Earth’s skin. Note that both aforementioned hypotheses indeed include an enhancing greenhouse effect in which more heat is captured by the Earth–atmosphere system. The main difference between them is how this additional energy is prevented from warming the Earth’s surface.

    H/T the GWPF [report continues – see Nature link above – this is only a small portion of it]

    Comment: looks suspiciously like an attempt to prop up ‘man-made greenhouse effects’ in the face of obvious natural variation.

    There seems to have been some kind of major misunderstanding about El Nino Modoki at wuwt. Above I’ve given a link to background reading. Anyone with the inclination will find it’s not difficult to create an El Nino Modoki index empirical ensemble via KNMI Climate Explorer’s “Make EOFs”.

    While messing around getting a handle on what the various authors have been going after I came across something really clean and simple — something else …and something a whole lot more important ….and it’s first order. I aim to illustrate by the end of September, possibly sooner.

    2005 – Interannual Variability of Patterns of Atmospheric Mass Distribution
    http://journals.ametsoc.org/doi/pdf/10.1175/JCLI3333.1

    There’s a tremendous amount of work to do in this area. Method development is far from finished. To me this is far and away the most interesting topic in climate discussion. It’s one sharp edge that cuts clean exploratory pathways.

    Taxpayer-funded explorers can be directed to develop evolving (in time) aggregation criteria capacity — i.e. facilitate not only non-square gridboxes to allow for diagonal lines and polygons but also shape-shifting to track (over time) architectural boundaries like the ITCZ …to get differintegral observation more finely tuned. Meanwhile we do things like 8 degrees North is the average ITCZ.

    This is a piece of work for patient programmers. The amount of work that needs to be done is formidable.

    RJ, perhaps we are having an absolutely brutal communication breakdown.

    I don’t mean to sound sarcastic, but to underscore a point I must ask:

    Do you acknowledge the existence of thermal tides?
    For example, have you ever heard of the day and year?

    Sometimes (whether by intent or accident) the obvious gets swept under the rug and frankly all that does is rouse (very strong) suspicions.

    On a less sarcastic tone:

    Are you taking care to differentiate between lunar and lunisolar?
    I’m open to the possibility that miscommunications are at least partially semantic in origin.

    The sun accounts for 85% of the variance.

    Distortion artists and deception agents are having a murderous field-day capitalizing on the opportunities presented by the scrambled residual 15%.

    OB
    Thanks for the reminder of Ian Wilson’s article. Ian appears to be correct as usual.
    I should have posted above that MEI ENSO is entirely a sun lunar earth tidal interaction.
    The timing of the new moon, full moon solstice and equinox are all factors in determining the MEI ENSO.

    It could maybe reach a wider audience with careful rewrite for simplified clarity …but it’s only necessary to reach luminaries …and so it’s sufficient as-is:

    “[…] because the Cross Equator SST Gradient (CESG) is southward, the cross equator northward wind, which decelerates trade winds north of the equator and accelerates those south of the equator due to Coriolis force […] Thus the evaporation of the northern tropics is weakened, thereby cooling down the northern tropical SST slightly. Vice versa […] Therefore, SST of northern tropical is much higher […] increases the CESG. […] positive feedback […] Wind-Evaporation-SST (WES) […]”

No problem if its -as oldbrew points-‘one borehole…..’, . That’s your Pareto Principle at work.

    An old groove (as in vinyl disc) of mine, real evidence of 2200 event comes in singular cases. In my case its dimensions in a contemporary building, others from ancient astronomical data. So when PV asks “Did the moon do something fantastic (!!) in 2200BC??”, I’ll point once more –look at all the evidence. I’ll add this: whatever the moon did(?) in 2200, it happened several times before in the holocene, between 1-6ky bce.

    “This change at 2,200 B.C. was a global phenomenon,” MacDonald said. “It’s associated with the collapse of the Old Kingdom in Egypt. It’s linked to the decline of the Akkadian Empire in Mesopotamia and similar Bronze Age societal disruptions in India and China. It was amazing to find evidence of it in our own backyard.””

    Let’s take a minute to add perspective….


    It is a long-standing mystery that the intertropical convergence zone (ITCZ) stays north of the equator over the Atlantic and eastern Pacific Oceans despite that the annual-mean solar radiation at the top of the atmosphere is symmetric with respect to the equator.
    […]
    While latitudinal asymmetries of land-sea distribution certainly are the ultimate cause of the perennial Northern Hemisphere (NH) ITCZ, the chain of causality is poorly understood.
    […]
    The atmospheric response to an eastern Pacific-type SST distribution–with an equatorial minimum and two off-equatorial maxima–is quite straightforward: It forms its ITCZ in the warmer hemisphere […]. How the atmosphere forms its ITCZ over a western Pacific-type SST distribution–with a broad equatorial maximum–is a matter of controversy […].

    http://iprc.soest.hawaii.edu/users/xie/ITCZ.html

    Now I ask the lunar-ENSO fans a very simple question:

    Have you seen anything in your lunar modeling adventures that would lead you to hindcast surface pressure patterns, sea surface temperature patterns, sea surface height patterns, wind patterns, thermocline depth patterns, and all the other coupled things to LOCK into a La Nina pattern FOR MILLENNIA???

    Suggestion 21:

    Use intense funding coercion to force the climate mainstream to understand what they don’t understand about ITCZ position with orders of magnitude more clarity.

    “This wind- evaporation-SST (WES) feedback is very effective in adjusting SST: a wind speed difference of a factor of two translates into a SST difference of 11 C […].
    […]
    A condition for this spontaneous development of latitudinal asymmetry is the equatorial upwelling that prevents the ITCZ from forming at the equator.
    […]
    A symmetry-breaking forcing by Americas […]”

    ((Divide and conquer anyone?….))

    I’ve looked into this and what I found is geometrically simple:

    5:1

    It’s a new approach to polarization.

    “Break on through to the other side” — The Doors

    Before we can go there there’s review of prerequisites people missed last time around (and the time before).

    oldmanK, they say 2200BC. Can you again concisely (a simple chronological list would be an effective way to stoke detective instincts) remind us of the key dates you’ve seen scattered around the symmetry-breaking incident?

    I do have new first order perspective to share. ITCZ asymmetry prerequisites come first. Hitting people over the head with 1+1 doesn’t assure capacity to recognize 2. (Willingness is another matter.)

    Leveraging the californian bubble and passion for lukewarm recruiting and marketing purposes was natural.

    We’ll also go over El Nino Modoki indices. You can blame a devilishly naive boss for hiring an advection and insolation clown who assumes spatial independence.


    […] the tropical ocean- atmosphere system contains two major feedback mechanisms: The Bjerkness feedback is responsible for equatorially centered phenomena like El Nino/ Southern Oscillation, whereas the WES feedback generates features anti- symmetric about the equator. Upwelling dominates SST variations on the equator, while surface heat flux becomes important off the equator where prevailing Ekman downwelling decouples SST from oceanic variability beneath.

    “Solar radiation” as the answer to “what drives ocean-atmospheric motion” would be considered too vague today. Only a few years ago, our answer–“land-sea distribution”–to “what keeps the ITCZ north of the equator” was as vague.
    […]
    Yet there are still gaps to fill: Which continental features are the trigger that puts the oceanic ITCZ to the north of the equator?

    Lunar modelers:

    Is your mind open enough to consider the moon a “continental feature”?

    Are you working on the Bjerkness feedback? or the WES feedback??

    Hint: What LIMITS the INTEGRAL of the Bjerkness feedback? Could it be the WES feedback?

    Is the sum of the parts the whole? …or are the parts a partitioning of the whole??

    You could put 10 moons in the sky and let them scramble (climate and human minds).
    Which limits would not change?? And on which axis??

    An exercise for modelers:

    How would QBO, AMO, & ENSO differ — or be the same — if Earth had 10 moons instead of one?

    Thermal and gravitational tides differ fundamentally. What comparative provocations are needed to correct thinking about aggregation criteria, axial differences, and limits? It’s something to explore.

  90. Paul Vaughan says:

    “The asymmetry of the east Pacific depends on processes that are notoriously difficult to capture in general circulation models (GCMs). […] Most atmospheric GCMs produce a tropical climate that is too meridionally symmetric, with southerly winds that are too weak and these biases tend to amplify upon coupling to ocean GCMs (above).”

    The inclination of the planetary system relative to the solar equator may be explained by the presence of Planet 9

    Rodney Gomes, Rogerio Deienno, Alessandro Morbidelli (Submitted on 18 Jul 2016)
    http://arxiv.org/abs/1607.05111

    We evaluate the effects of a distant planet, commonly known as planet 9, on the dynamics of the giant planets of the Solar System. We find that, given the large distance of planet 9, the dynamics of the inner giant planets can be decomposed into a classic Lagrange-Laplace dynamics relative to their own invariant plane (the plane orthogonal to their total angular momentum vector) and a slow precession of said plane relative to the total angular momentum vector of the Solar System, including planet 9. Under some specific configurations for planet 9, this precession can explain the current tilt of approximately 6 degrees between the invariant plane of the giant planets and the solar equator. An analytical model is developed to map the evolution of the inclination of the inner giant planets’ invariant plane as a function of the planet 9’s mass, inclination, eccentricity and semimajor axis, and some numerical simulations of the equations of motion of the giant planets and planet 9 are performed to validate our analytical approach. The longitude of the ascending node of planet 9 is found to be linked to the longitude of the ascending node of the giant planets’ invariant plane, which also constrain the longitude of the node of planet 9 on the ecliptic. Some of the planet 9 configurations that allow explaining the current solar tilt are compatible with those proposed to explain the orbital confinement of the most distant Kuiper belt objects. Thus, this work on the one hand gives an elegant explanation for the current tilt between the invariant plane of the inner giant planets and the solar equator and, on the other hand, adds new constraints to the orbital elements of planet 9.

    Since landing a significant finding last week (illustrations forthcoming in the weeks ahead) I’ve begun digging around in whatever strained spare time I can manage for background info on ITCZ definition, aggregation criteria, climatologies, etc.

    The lack of search results (using keyword combos tried so far) suggests this is an area of too-deep mainstream ignorance. I suspect that better (specifically less ignorant) attention in this area will result in an orders-of-magnitude increase in clarity of climate perception.

    There may be superior, supplementary, and/or complementary info out there that I haven’t yet hunted down, but so far I’ve turned up 2 nice clues about the roots of the global-scale pattern partitioning I’m detecting:

    1.

    “Our wind climatology of the ITCZ contains a single ITCZ characterized by large seasonal migration; over the global ocean the ITCZ location shifts by about 20° between July and January (Figure 2g). The corresponding shift of the precipitation maxima is about 4° (Figure 2d).”

    2. ocean
    3. land
    rows:
    1. TRMM precipitation
    2. ERA Interim precipitation
    3. meridional wind
    4. meridional wind convergence

    http://onlinelibrary.wiley.com/store/10.1029/2011JD015695/asset/image_n/jgrd17142-fig-0002.png?v=1&t=it8voail&s=f6a462bcb4b4a3a54c42066efadb8a427ece72f2

    Looking across the 3rd row (meridional wind where a positive value indicates northward wind and a negative value indicates southward wind) you can see that monsoons over land (3rd column) are blowing out the global zero-crossing extremes.

    From the ocean illustration (3rd column, 3rd row = panel h) looking at July (red) and January (blue) we see that annual meridional wind zero-crossing migration is from roughly the equator to 15°N.

    Such clear and simple insight immensely helps guide sorting and detection of multidecadal-to-centennial spatiotemporal pattern.

    2.

    Illustrations here further underscore 0-15°N intensity with eye-catching triangular patterns:

    2002 – Wind Convergence Observed by QuikSCAT – Liu, Xie, & Tang (NASA JPL)

    See particularly sections “3. Intertropical Convergence Zones” & “4. Wind and Sea Surface Temperature Coupling”

    “Fig. 6 Latitude-time variations of meridional components of surface wind from ERS scatterometer (upper) and SSM/I (lower) in the eastern tropical Pacific.”

    “Fig. 5 Latitude-time variations of (from top to bottom) surface wind convergence (10^(-5)/s), meridional wind component (m/s), cloud liquid water (mm), and sea surface temperature (°C), from QuikSCAT and TMI, averaged over (a) 5°W-15°W, (b) 25°W-35°W, and (c) 95°-105°W. On the back line, the meridional wind is zero.” (Interpretive caution: column 1 latitudinal range = 10S-10N versus 15S-15N for columns 2 & 3.)

    Some key notes from the article:

    1. “The high accuracy and resolution made it possible to compute derivative quantities, such as atmospheric wind convergence, which reveal details of the atmospheric processes [Liu, 2002].”

    2. “Despite many studies, the existences and seasonality of the ITCZ south of the equator is still controversial. By definition, ITCZ should be examined through surface wind convergence, but surface wind convergence are largely not available in the past because of the poor resolution of wind maps computed from routine ship reports. Two different mechanisms which distinguish the formation of stronger from the weaker ITCZ were revealed by the vector winds from QuikSCAT and the sea surface temperature (SST) from the microwave imager on TRMM [Liu and Xie, 2002].”

    3. Near the equator, -∂u/∂x is much smaller than -∂v/∂y; wind convergence is dominated by the meridional gradient of the meridional wind component.”

    4. “The Atlantic, south of the northern ITCZ, is largely dominated by southerly winds, all year round.”

    5. “There are two scenarios to achieve local maximum of C. […] The coexistence of a stronger convergence zone on one side of the equator with a weaker one on the other side cannot be explained with the same mechanism.” (They postulate 2 different mechanisms (see paragraph 1 of p.6).)

    6. “The scenario is similar in the eastern Pacific (Fig. 5c), except that during boreal springs, the northerly trade winds cross the equator and meet the southerly trade winds at the stronger convergence south of the equator.”

    7. “For the long time series in the Atlantic, the stronger convergence zone is always in the north and weaker one in south consistent with two mechanisms we postulated.”

    8. “[…] wind divergence is in quadrature rather than in phase with SST.” (from section “4. Wind and Sea Surface Temperature Coupling”) “Similar relation between SST and surface winds appears to be much more prevalent. It was observed in the cold patches left behind typhoon passages […] and even over Gulf Stream rings […] similar relation in the Asian marginal seas. The vertical mixing mechanism appears to be applicable over a broad spectrum of temporal and spatial scales over different regions. (Connection: Recall the work of Jose Rial. We’re dealing with fractals. Although working on different timescales, Rial and I both developed sufficient awareness of aggregate differintegral structure to make downscale inference.)

    Another illustration turned up by the search engine:

    These illustrations remove much of the mystery about how insolation and land-sea geometry sort sea surface temperatures zonally (explaining 85% or more of global SST variation). I’ll be reviewing last week’s findings in light of the above, which suggest (minor) refinements to the aggregation criteria.

    In combination with a semi-annual (spring/fall) reinterpretation of Trenberth, Stepaniak, & Caron’s (2000) CEOF2, this also opens up new avenues of tropical east-west axis (including ENSO) exploration (to probe the residual 15% or less of global SST variation).

  94. oldmanK says:

    PV in above asked “oldmanK, they say 2200BC. Can you again concisely (a simple chronological list would be an effective way to stoke detective instincts) remind us of the key dates you’ve seen scattered around the symmetry-breaking incident?”

    Its best to refer again to chart here: https://www.facebook.com/melitamegalithic/photos/a.531276403713836.1073741848.430211163820361/531276417047168/?type=3&theater Since I mentioned this chart some time ago I have confirmed its correct. That chart shows a precursor to the 2200bc event–at 2345–that is supported by various evidence:
    a—Dodwell’s paper to the Astro society. b—same date highlited in dendrochronology. c—a megalithic calendar converted to a higher obliquity but no clear date except between 2900-2200. d—the chart indicating polar warming but equatorial cooling at about ~2400. e—evidence from Quelccaya glacier of permanently frozen plants dated initially to an event ~5000 years ago (3000bc), but that number has since been revised downwards. It would happen with abrupt insolation reduction between tropics as chart indicates.

    The calendars indicate earlier obliquity swings. The chart at 4375bc again indicates similar polar warming but equatorial cooling at about the right time a calendar was built to a higher obliquity (ie chart, date and indication from calendar dimension agree). An even earlier instance exists in the chart at 6150 or 6200(?), a date that is linked to the sinking–or flooding–of Doggerland, but nothing else at this early period.

    Then in between there are reverse events, but only one is firm. About 3200–precise at 3195 from dendrochronology,– occurs the Piora Oscillation. It is linked to cataclysmic (ugly) events because there is an orientation change in the new calendars and total abandonment of all earlier. However cannot yet interpret chart. It is also linked to earlier civilisation collapse.

    Chart originates from Wiki–holocene temp variations, all O2 isotope. To note: averaging hides and obfuscates rather than gives clearer indications.

  95. Paul Vaughan says:

    of course …and image searches often work better than regular searches. Strained time is one limiting factor and the other is that the mainstream hasn’t done as much work on ITCZ migration as I would have imagined. The info I’ve posted just above is enough for the explorations I’m pursuing, but I’ll also spend more time mapping out mainstream awareness as time permits.

    Something of ‘mutual’ interest — ITCZ related. It relates to a period in the Holocene, but shows something else — to me interesting. The subject: “Holocene Forcing of the Indian Monsoon Recorded in a Stalagmite from Southern Oman”

    http://shadow.eas.gatech.edu/~jean/paleo/fleitmann03.pdf

    In fig.1 particularly there can be identified ‘down-turns’ at 8200BP (~6200 bce) and ~6400BP (~4375bce). Then up-turns at 5000BP (~3000bce)…..plus others that might fill some gaps, — but cannot tell yet.

    Fig 3A shows relationship to insolation and -my interpretation-seem to indicate system(?) instability. The more so since at about 4500BP (~2345bce) it becomes more stable; a fact that is known from megalithic calendars since the periodic great destructions stop.

    Note fig2 chart a, the smooth dotted line representing insolation is a wrong assumption, since from 4,5ky to 6,6ky other evidence says that obliquity was changing way beyond either side of the 22-24 deg. secular swing.

    For many this is difficult to accept, but its now a case of ‘faith-in-dogma’ against evidence.

    The Cycloid and the Kinematic Circumference
    http://milesmathis.com/cycloid.pdf

    MM quote: If you roll a wheel on the ground one full rotation, it will mark off a path on the ground that is 2πr in length, as most people know. That length has been assigned to the circumference of the circle or wheel, which assignment is correct as far as it goes. My papers have not questioned that. However, if you do the same thing but follow the motion of a given point on the wheel (point A in the diagram above, for instance), it draws the red curve. That is called the cycloid. Obviously, the red curve is not the same length as the line on the ground. It is considerably longer, being 8r in length. That is 21% longer than the circumference.

    Wikipedia confirms:
    Another immediate way to calculate the length of the cycloid given the properties of the evolute is to notice that when a wire describing an evolute has been completely unwrapped it extends itself along two diameters, a length of 4r. Because the wire does not change length during the unwrapping it follows that the length of half an arc of cycloid is 4r and a complete arc is 8r.

    Earth Wobbles May Have Driven Ancient Humans Out of Africa

    Previous research suggested that shifts in climate might help explain why modern human migrations out of Africa happened when they did. For instance, about every 21,000 years, Earth experiences slight changes to its orbit and tilt. These series of wobbles, known as Milankovitch cycles, alter how much sunlight hits different parts of the planet, which in turn influences rainfall levels and the number of people any given region can support.
    http://www.space.com/34158-humans-left-africa-due-to-earth-wobbles.html

    ‘known as Milankovitch cycles’ – surely not? More like precession of the perihelion IMO.

    Wikipedia says: it takes about 21000 years for the ellipse to revolve once relative to the vernal equinox, that is, for the perihelion to return to the same date

  105. oldbrew says:

    TB: OK but see my e-mail.

    There is more than one type of precession, but only one can be Milankovic if the other two M cycles are 41k and 100k years.

  106. oldbrew says:

    A case can be made that apsidal and axial precession are related, as I tried to show here:
    https://tallbloke.wordpress.com/2016/02/01/why-phi-a-unified-precession-model/

    From the ‘quarter precession’ model:
    4 x 6441 tropical years = 25764 TY (= 26,000 years axial precession in TB’s diagram above)
    13/4 x 6441 tropical years = 20933.25 TY (= 21,000 years apsidal precession in the diagram above)

    So their ratio is 16:13 according to the model. Axial relates to sidereal years and apsidal to anomalistic years.

  107. oldmanK says:

    TB, I would query the ’tilt’ in that chart, plus some other issues as well.

    In a chart I have referred to before, I have just added material culled from the paper “Holocene East Asian monsoon variability: Links to solar and tropical Pacific forcing”. It shows abrupt changes in the K/Br ratio from figure 1 of the paper, and superimposed to same time scale. On my part its maverick work but it provides a couple of evident correlations to other evidence, e.g. indicating greater tilt changes than appear in the chart you posted. It also means the events in the Holocene were widespread and global. still early work.

    A lot is being said presently on the Holocene, but one thing is quite certain. It was not only climatic events but definitely also astronomic and very seismic, and possibly cyclic with cycle near 2k (but only 1+1/4 show). These show on a centennial scale but would be completely hidden on larger scales.

    My primary aim is to date the calendar dates and events. But may be found interesting in other respects.

    Below is an update to the actual versus the prediction of the LOD model as of August 30, 2016. This update includes lunar phases as it could be that the timing of the Lunar phasing this year with the seasonal variation has accentuated the slow down in the earths rotation. If so, then the actual LOD should trend back to the model LOD as the lunar phases move into a position that pulls water away from equator as the moon swings north and south.

  121. Paul Vaughan says:

    RJ, you’ve got a clear refinement diagnostic there: the biggest failures are in summer and winter. That’s semi-annual. Are you excluding the solar cycle effect on semi-annual volatility from your model? If so, why? (It’s the biggest thing.)

    Just wanted to also note that continental drift pays a major part in these cycles.

    If there is not enough land mass at 75N or 75S, the Milankovitch Cycles have no impact. Really large continental scale glaciers cannot build up on the ocean at 75N, only land-based glaciers can.

    One issue with the ice ages which is also important, is that if glaciers build up on land at 75N or 75S, they can depress the land enough so that is now becomes Ocean for up to 1.0 million years at a time and this can suppress glacial activity for a long period of time.

    For example, we have Hudson Bay, and the Barents Sea and the Kara Sea and East Siberia Sea which were all above sea level until 2.0 million years ago or so. The glaciers that built up starting at 2.6 million years ago, pushed them below sea level and this completely changed the impact of the Milankovitch Cycles. The timelines of glaciation then do not compare to what really happened with solar radiation at 75N because now we are dealing with ocean conditions which were previously land conditions.

    As North America has slowly rotated more north-west, this left more and more landmass above sea level so that that Milankovitch Cycles could begin to have an impact in the last 2.7 million years. Before this time, it was too far south for glaciation. As northern Eura-Asia dropped lower and lower because of previous glaciations starting at 2.7 million years ago, this also affected the timeline of Milankovitch Cycle impacts.

    When Gondwana moved across the South Pole between 460 million years ago and 290 million years ago, there are periods when glaciation could not happen because all of the landmass was pushed below sea level due to previous glaciations.

    – UK – Brexit economic reality shock

    – cesspit of international warmongering in Syria and rise of Russia assertiveness.
    – loss of credibility and control by major Central Banks.
    – deluded, ideologically AGW-driven energy policies (think South Australia blackout) coming against the reality of a cold climate cycle.

    OB if this is what you’re hinting at, it’s mathematically equivalent to what I illustrated about SCD 5 or 6 years ago and to what Jose Rial has illustrated at higher timescales:

    You may be correct if you’re subtly advising that people do not realize this yet. It should have been obvious to them right away (it’s an implication of the simple algebraic proof), but maybe it wasn’t.

    There’s some fun history on the wiki pages for anyone linking through them: Galileo, Lagrange, Newton, Bernoulli, Euler, etc., …and the development of the calculus of variations itself was needed to finish solving the problem (why Galileo got stuck in his time).

  138. oldbrew says:

    oldmanK – wouldn’t that cause the ball in the curved pipe to decelerate due to increased air resistance? We don’t see that, as the video shows.

    The cycloid itself isn’t a joke. Half the cycloid = Pi = 4 bars on the x axis (graphic below).
    The video is at ‘youtube.com/watch?v=ohP0clzK5rc’ – commentary explains the graphic.

    A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slippage. It is an example of a roulette, a curve generated by a curve rolling on another curve. – Wikipedia

    Another immediate way to calculate the length of the cycloid given the properties of the evolute is to notice that when a wire describing an evolute has been completely unwrapped it extends itself along two diameters, a length of 4r. Because the wire does not change length during the unwrapping it follows that the length of half an arc of cycloid is 4r and a complete arc is 8r.

    Oldbrew, the math is ok but the experiment is another thing. Both balls are decelerating, losing their gained energy from the drop. The greater the resistance the shorter the travel. The ball forced into the circular pipe is also imparting momentum into the plastic pipe wall.

  141. Paul Vaughan says:

    oldmanK, experimenters can use a particular solution to design an apparatus. OB is engaging in strategic provocation. Something I’ve come to realize from years of immersion in the climate discussion is the utility of such provocation. By introducing a particular solution, OB has reminded us of 3 papers we discussed a few years ago (on wind and land-ocean phasing relative to insolation). It’s now a good time to go back and review them with the benefit of hindsight.

  142. oldbrew says:

    The experiment is only an attempt to illustrate the principle (cycloid = 8 radii), which is accepted maths as far as I can tell. The real interest lies in identifying ‘cycloid situations’ so to speak.

    For example, Wikipedia says:
    ‘A cycloid is the curve traced by a point on the rim of a circular wheel as the wheel rolls along a straight line without slippage. It is an example of a roulette, a curve generated by a curve rolling on another curve.’

    Is a planet orbiting the Sun similar to this description?

    NB Wiki quote may be poorly phrased, mixing straight lines and curves.

  143. Paul Vaughan says:

    As the US election approaches, the level of misinformation being put out by Cal-Lukes and associates (in staunch support of Washington & Hollywood mainstream elite status quo) is going off the charts.

    First, here’s a cautionary note:

    Recently we saw a prediction of 2017 cooling. We’re still on the BDO (bidecadal oscillation) UPswing untill 2020 and it doesn’t turn negative (in central limit) until 2025. NOWHERE during the observational record have we EVER seen substantial cooling during a BDO max:

    The BDO can delay the (noticeable portion of the) downswing.

    We also still have not turned around on the polar asymmetry cycle (watch for stratospheric volcanic activity). The northern hemisphere is still on a high. That’s zero-sum, but most people live in the north.

    Milankovitch misrepresentation is also off-the-charts again. It’s so ridiculous. There’s lots of discussion COMPLETELY ignoring the following:

    Precession controls the monsoons. Eccentricity controls equatorial SST and poleward advection potential. People always talk about obliquity controlling local polar radiation, but they ignore its role in realizing poleward advection potential set by eccentricity. And finally: Geography is a BIG trump card.

  144. Paul Vaughan says:

    There’s widespread ignorance of the following:

    Maximum tropical insolation over the year minus minimum polar insolation over the year = eccentricity.

    This controls the potential to spray water poleward (including over orographically desiccating mountain ranges) to overwhelm the input side of the mass balance equation.

    There’s too much focus on the summer radiation melt side of the mass balance equation and not enough appreciation and respect for the potential of the input side to overwhelm the poles with tropical spray. (Wet spraying and dry heating aren’t the same thing.)

    …And of course ignorance of the role of geographic change — e.g. open/close Drake Passage & Panama Isthmus, depress/uplift northern continents changing sea level, deepen/shallow &/or reroute gulf stream, cluster/disperse and/or tectonically move continents poleward or equatorward, etc. — on circulatory architecture is epic.

    Careful, concise distillation to cut through misinterpretation / misunderstanding / misrepresentation is feasible.

  145. oldmanK says:

    PV said “OB is engaging in strategic provocation.” I suspected as much. But I think it helps to call out errors, — just in case. Then OB says “The real interest lies in identifying ‘cycloid situations’ so to speak.” A classic case is the lead weight that balances car wheels. Wheel balance is made with that weight in circular motion, yet in action the weight it traces a cycloid.

    PV (and others), in the above graph of Insolation there is an assumption that obliquity is within the 22-24 deg bounds. Mathematical analysis gives that answer because it was originally based on a fallacious assumption to start with. Maths is ignorant of archaeological findings, and those tell a different story. The empirical factor in the maths appears, from archaeological evidence which is better than any other proxy in this case, to change –arbitrarily, or chaotically or by some design,-but it changes, way beyond what is assumed.

  146. Paul Vaughan says:

    oldmanK, note that that’s the equator, so you’re looking at precession and eccentricity (not obliquity). Moving out towards the poles you’d see obliquity pronounced.

    I have no idea when I’ll ever have time, but as I mentioned a long time ago the climate discussion community would benefit from a SINGLE SIMPLE 4-DIMENSIONAL illustration of insolation.

    There gets to be such BS in Milankovitch discussion because there are too many participants who don’t visualize it in 4D. They instead conceptualize based on SELECT CROSS-SECTIONS. They focus on insolation rather than CIRCULATORY ARCHITECTURE EVOLUTION (including hydrology).

    The mass balance equation has 2 sides, but they focus ONLY on 1 side of it.

    For example have a look at the recent thread at ce on dust. It does not diagnose the hydrological cycle (circulatory architecture reconfiguration) as the SHARED cause of synchronous regional symptoms (dessert dust and ice mass balance change).

    They’re always going on about insolation melting snow with never a thought devoted to changing tropical water pumping through the sky to the glacier. They don’t properly differentiate precession and obliquity effects on flow-driving insolation gradients.

    More generally they fixate on local radiative effects OBLIVIOUS to the implications of spatiotemporal insolation pattern change for CIRCULATORY ARCHITECTURE EVOLUTION. It’s completely moronic and infuriating at the same time.

    Everyone has their very own personalized interpretation of what “Milankovitch” means.

    Almost no one has a broad, generalized, adaptable (iteratively refined) interpretation of what it means. The definition most people are using is conceptually corrupt. The discussions go to h*ll.

    There are a lot of commentators deliberately being devilish just to infuriate others they perceive as political dissidents — a culturally-infectious, vicious psychological tactic that warrants banishment …but its encouraged by the hosts at ce & wuwt, thus clarifying the cultural goals in those venues.

    Reassurance: We know mysterious deviations have occurred.

    Recap: You’ve pointed out a deviation that interests you around something like 2000BC along with a handful of others.

    REQUEST: If you have observational evidence of deviations at Milankovitch timescale (as opposed to instinct-based extrapolation from the Holocene), please enrich the discussion by raising our awareness with an illustration (…reminder: NOT interested in links to sites demanding that I set up an account).

    (Analogy: We don’t have sunspot integral and solar cycle length differintegral observations at Milankovitch-timescale.)

    QUESTION: As a basis against which to compare deviations that interest you, would you rather assume a flat 0 variation backbone everywhere? I’m sure you won’t be able to convince many people that’s a better reference. What anomaly baseline do you propose if you dislike the conventional one?

  147. Paul Vaughan says:

    oldmanK, perhaps there’s opportunity that some other strategic questions can advance our understanding of your concerns…

    Reflecting I can only remember you leveling observation-based complaints about conventionally modeled obliquity.

    Question: Do you have any observation-based challenges to assumed precession and eccentricity?

    I just had an idea that might help reconcile your concerns with conventional thinking …but I want to differentiate a little more thoroughly before going there.

    I can actually see a way that both you and the mainstream are right …and like usual it comes down to recognizing false assumptions (misinterpretation of observations that are informing about something else that’s important…)

  149. oldmanK says:

    PV Quote “oldmanK, note that that’s the equator, so you’re looking at precession and eccentricity (not obliquity).”

    If obliquity is reduced for reasons as said above, insolation at equinoxes is unchanged but at any other time of year there is an increase, eg at a 14.5 deg obliquity tropics are narrower, the spread of solar heating is more concentrated. Beyond ~lat40 there starts a decrease. It may not be much change up to 60deg latitude but then change increases faster.

    Someone – presently I cannot find the source- said there cannot be polar ice build-up at present obliquity (and 22-24 deg is a small change). At about 14.5 (as per the archaeological source) it is a different matter especially polar regions, and holocene matters take on a different aspect.

  150. Paul Vaughan says:

    ….so because of 1 datum at 2345BC (and nothing before then) you want the baseline changed to 0?? ….or do you think it makes more sense to keep the conventional baseline and note with emphasis the anomaly?

  151. oldmanK says:

    PV, the 2345bc datum is a date from another independent source (which thus also corroborates). ‘My’ source gives no reliable dates (I learnt to distrust proxy C14) , but gives a reliable obliquity value of a ‘before and after’. That value changed back and forth but outside the 22-24 limits– for reasons (and dates) that I seek to find reliably, though I have rough indications. Indications strongly suggest my source covers or goes back to ~5000bc.

    That is all I can say -with conviction-. I have asked myself this: does it take circa 2000 years of building calendars to get the two horizon solstice sunrise positions correct? (when one can find that out in a year). The last modification is correct still – and tested with surprisingly accurate results; in fact it beats anything used today for solstice day prediction from observations – to the credit of the ancient astronomers.

    Re: “….so because of 1 datum at 2345BC (and nothing before then) you want the baseline changed to 0??” Well what can I say? I come from a field where the singular anomalous failure eventually leads to the destruction of the whole. We look out for such with “seven eyes”.

    Then: “or do you think it makes more sense to keep the conventional baseline and note with emphasis the anomaly?” The answer in No, for two reasons. 1) A lower obliquity during the holocene changes many things – which leads to a better understanding of recent/any climate change. 2) Not tying obliquity to a narrow limit opens a whole can-of-worms –weather; glaciations; geological history; history of humanity…….none of which are understood, maybe in some measure due to a mathematical fixation.

  152. Paul Vaughan says:

    1. In your view, are the conventional PRECESSION and ECCENTRICITY baselines (note the absence of obliquity in this list) wrong BASED ON OBSERVATIONAL EVIDENCE?

    2. Humans make all kinds of clumsy mistakes and play all sorts of games. They’re also stubborn about admitting mistakes and it may become tradition to stick inter-generationally with inherited mistakes. Despite the perfection of some instrument, what if the people who oriented the structures and calendars were drunk, made a mistake, had a sense of mischievous fun, were reporting to a difficult boss who was threatening, deluded, misguided, or messing with the populace, or whatever?

  153. Paul Vaughan says:

    3. Are you suggesting some archaeological data from the Holocene imply that conventional obliquity models are wrong from 3Ma to 0.8Ma?

    4. Are you suggesting authorities are lying about current obliquity?

    Note to other readers: I’m trying to map out oldmanK’s thinking more precisely …including any assumptions and extrapolations. Is this the best use of my time? Definitely not.

  154. oldmanK says:

    PV: reply to 1) and the earlier question ” Do you have any observation-based challenges to assumed precession and eccentricity?”, the answer is no.

    On 2) I think I understand your concern, and it is something that I thought about for very long before taking the risk of making a fool of myself (and I would not have done it if I still had a career to protect; one speaks out late in life when its safe). There are 1001 reasons, and an infinite number of ways, of doing what you said. But only one studied way of doing it right and precise every time. In that respect one can also see where cult took over and messed it good and proper.

    As an engineer I marvel at the ingenuity in the last functional stages — No, they were not drunk. Searching Wiki on how to determine the solstice day (and no forecast)– I feel we today are a bunch of smart asses.

  156. RJ Salvador says:

    I hope you all find this as unexpected as I do. Below is a graph of the residual of the LOD model with its 120 day rolling average. This is the LOD minus the LOD model.

    The shape of the 120 day rolling average looked familiar so I graphed it together with the ENSO. Below you can see the very strong coherence between the Residual 120 day average times 4000 and the ENSO.

    The implication is that the model over its present range accounts for most of the LOD changes except those caused by the ENSO. Those changes caused by the ENSO are very small and of the order of 10 to the minus 4 of a second.

  157. J Martin says:

    Clive Best thinks that he Holocene will last another 15000 years because eccentricity is at a minimum. I think that would depend on whether the planet is on the warm side or the cold side of the goldilocks orbit. As we are on the cold side I think he’s wrong and the glaciation will procede as usual.

  160. oldmanK says:

    PV, I missed your Q 3 and 4 before replying, so here’s the answers to those.

    3. existing archaeological evidence gives good to precise indication of obliquity between 5k-2k bce, measurable from several sites ( besides a good lesson on astro-engineering).

    4. No. No one has figured out before, that what they believed were female-shaped cult spaces were – and still are- functional calendars, and then what their design implied. I tested the technique of both early and later designs and they worked perfectly. Most are, or have been forced into obsolescence by geological events (now with enough evidence). The last from that era is still functional. I have voiced this publicly only here (apart from an ‘unknown’ publication). This could be a hard landing for many who built stories about them, so ????

    To counter “Is this the best use of my time? Definitely not.” I understand your feelings. I might feel the same today, except that the free debate here is and remains enticing. What I thought was an elevated science, now seems, er- like the geocentric model of the universe; bound in dogma – all because it has ignored in the past those who did point to the anomalies. As it is I’m not saying something new, just pointing to the proof.

  161. Paul Vaughan says:

    oldmanK, you’ve misread Q3.

  162. oldmanK says:

    PV , apologies. Possibly more than question 3. (I came back to switch off from the twilight zone after two hours nearly unconscious listening to world politics – and I found Q3,4).

    Re Q3 I’m suggesting nothing – except point out to evidence ( evidence that in time I found reasons to consider it reliable) that says between about 5k to ~ 2.3k bce obliquity was substantially different/lower than anticipated from formulae. My past efforts in following this site and others were to verify solidly that point. The implications would then be multi fold.

    An addition to Q4, I do not blame the ‘authorities’ for being wary of the ‘maverick’ who first pointed out that ‘probability’ early last century, but ignoring him was a mistake.

  163. Paul Vaughan says:

    oldmanK,

    Recap:

    You have no observational challenges to conventional precession and eccentricity modeling.

    You have no major observational challenges to conventional obliquity modeling outside of ~5000BC-2300BC and the challenges you have inside that interval (something I won’t be making time to verify firsthand as there are far too many competing obligations of much higher priority level …so it will have to be others who look into this) are based on assumptions about human behavior — an extremely untrustworthy thing in my experience and I’m certainly not willing to rule out the possibility that anomalies were anthropogenically dictated by an oppressive boss — something quite normal in human society – definitely the norm.

    Nonetheless, until I see natural (never mind anthropogenic) observational evidence (never mind theory) convincing me otherwise, my mind is open to the possibility that obliquity fluctuates (maybe even jolts) around the conventional obliquity model …which remains the best central limit and baseline we have against which to put anomalies in context.

    The few Wittman (1979) data there are bounce around the central limit of the conventional models (Newcomb (1906), Wilkins (1960), Laskar (1986), & Astronomical Almanac (2010) are so close to one another they’re indistinguishable on graph below), so conventional modeling DOES appear to represent the central limit.

    Again: Until I see natural (never mind anthropogenic) observational evidence (never mind theory) convincing me otherwise, my mind is open to the possibility that obliquity fluctuates (maybe even jolts) around the conventional obliquity model …which remains the best central limit and baseline we have against which to put anomalies in context.

    This subject is taking a grossly disproportionate share of available harshly-limited time.

  164. Paul Vaughan says:

    J Martin,

    “Basically we are already at the end of a low cycle right now and the next low cycle is 52,000 years out. But I don’t think a 15 W/m2 drop at that time versus today is enough to put us into an ice age. The next big drop is 130,000 years from now which itself may not be enough for ice age as well (probably close though).”

    PEI reports: German power link to treble in cost to $16.7bn

    By Diarmaid Williams
    International Digital Editor

    TenneT have confirmed that the cost of the vital Suedlink power transmission link in Germany is to treble in cost.

    Ulrike Hörchens, press spokesperson for the company told Power Engineering International, “At the moment we are in an early planning phase and can only roughly estimate the costs for the two DC-projects. For both projects together we estimate the costs at €14bn to €15bn ($16.7bn).”

    The increase in costs is due to a decision by the government to use underground cable, because of public resistance to overhead power lines on the landscape.

    Paper: Solar Activity Modulates the Frequency of Central European Floods

  168. oldmanK says:

    PV, you have put two conclusions that do not follow the logic. For the sake of record this is the converse (then drop it by all means).

    1. Quote “You have no major observational challenges to conventional obliquity modeling outside of ~5000BC-2300BC”. If the modelling does not hold in that stretch of time, then it is faulty for all the rest. To be precise that piece, on my part, is inferred not proof, but then that is what the model does – infer only, it is not proof -. The reason I see for that is that the model was figured only for secular planetary dynamics without any consideration of possible transient changes or jumps, a normality with most dynamic systems.

    2. Quote “are based on assumptions about human behavior “. Not quite, by a long stretch. What its based upon is tangible (actually a large building – several) with design and dimensions and a technique that one can reverse engineer and dissect with a relatively high degree of certainty. As against a mathematical model which (to my mind) is a similar case to Ptolemy’s geocentric model – for reasons as in 1.

    3. Qoute “conventional obliquity model …which remains the best central limit and baseline we have against which to put anomalies in context”. I like this, if nothing else but to point an accusing finger (not at PV). History is a good teacher. The ancient Greeks were already working on the Heliocentric idea. We give a lot of credit to Ptolemy where it is not deserved ( and for more than one issue). A bigger establishment used Ptolemy’s idea, and all know the rest. And history repeats itself too.

  169. Paul Vaughan says:

    oldmanK wrote: “If the modelling does not hold in that stretch of time, then it is faulty for all the rest.”

    No for 2 reasons.

    There are other terrestrial variables that MATCH the modeled obliquity. That’s why I picked the 3Ma-0.8Ma example (an example most will be familiar with) to see if you would acknowledge that. I note that I’ve raised this 3 times now and so far you’ve not acknowledged. I picked a very well-known simple example on purpose.

    Also, the model may be just fine in central limit and you may be pointing to an anomaly. That’s what other variables suggest when you put things in long-run multivariate context.

    You may be drawing attention to a source of variation AROUND the central limit. You may very well be correct that the mainstream is ignorant of such sources of variation, BUT IT DOESN’T NECESSARILY MEAN THEIR MODEL OF THE CENTRAL-LIMIT IS WRONG …and you should at least acknowledge that in the multivariate longer-run OTHER variables suggest the mainstream is NOT wrong IN CENTRAL LIMIT.

    Gentlemen: You may have something important to say about this, but it needs to be consistent with OTHER multivariate observations of obliquity in the long-run.

    Request: OB (or anyone), please link to plain-text data. (I’ve seen the Dodwell graph and thread before.) To explore the data, I need the data. (It looks like there are a few data on the graph that are not in Wittman (1979).)

    There’s hardly any data with which to explore this (…and the few more Dodwell data won’t change that).

    It is what it is:
    an unexplained anomaly that’s shelved until substantial new info triggers a revisit.

    No damage has been done to the long-run central limit model. Only a suggestion has been made that there are additional sources of variation about the central limit …and certainly that much is well worth our attention.

    On the Pareto Principle with NO link provided to a plain-text Dodwell data page I focused on “KARNAK” which was the ONE thing in the Dodwell illustration that jumped out as significantly different from Wittman (1979).

    “In ancient times Egypt was pre-eminently a centre of Sun-worship. […] The Great Solar Temple of Amen-Ra at Karnak […] the orientation of the original axis of the temple, was 25° 9’ 55” […] The Obliquity given by the solar orientation of the Temple of Karnak, 25° 9’ 55” […] there must be some other factor, in addition to those which are represented by Newcomb’s Formula (or equally by Stockwell’s Formula), affecting the sun’s apparent position in past ages. […] Karnak Temple […] building period […] approximately 475 years (2045 B.C to 1570 B.C.) […] a particular type of mathematical curve, namely a logarithmic sine curve, which provides its own determination of the date of its starting point in 2345 B.C.” (2345BC is an EXTRAPOLATION.)
    http://www.setterfield.org/dodwell_manuscript_8.html

    “[…] what is the significance of the azimuth of the axis at Amun Re? The authors of the temple study have an excellent suggestion. They also tabulated the angle that the axes of symmetry made to the direction of the flow of the Nile River at each location. Most axes, including the one in question here, are aligned at right angles to the river. This suggests that once a site for a temple was selected, the axis was laid out so that one viewed the axis of symmetry as one approached the temple from a boat on the river. This makes sense, because most sites probably had boat landings at their entrances, and so this would have grand entrances for nearly everyone who visited the sites.”

    I reached the “aha!” moment when I read this:

    “[…] the 2345 BC date for the dramatic change in the earth’s axial tilt is very close to the Ussher chronology date of the Flood (2348 BC).”

    I wasn’t aware of religious dimensions fueling the fuss.

    All along I’ve been wondering why there’s such a fuss about a few anomalous data points that can be patiently shelved awaiting new clues and/or revelations.

    Now I get it.

    People excitedly looking at it this way might not have observation-based long-run multivariate perspective.

  172. oldmanK says:

    PV, first TY for the reply. We may be getting somewhere, but to clarify further from my side, I hope, lets tackle some points:

    Quote “There are other terrestrial variables that MATCH the modeled obliquity. That’s why I picked the 3Ma-0.8Ma example (an example most will be familiar with) to see if you would acknowledge that.” I am not familiar with that region so cannot comment. I stick only to the ~5k to 2.3K. However that “there are other terrestrial variables that MATCH the modeled obliquity” may be so, but not because it is dictated by the model, but for other reasons. The model may only appear to dictate.

    To illustrate better, with a little patience from readers, download this: https://archive.org/details/memoirofsecularv00stocrich –the work of JN Stockwell. Go to page 180, part6, which will refer you to eqn (566) on page 178; note that all is computed around the “as is” value of obliquity of year 1850, an empirical constant. The computations give the secular motions. However the empirical constant is and remains an unknown entity. If it changes the model ‘likely’ still holds, but there would be other ramifications. The main thrust of my argument/claim is that that number has changed in the holocene.

    Or go to Wiki here: https://en.wikipedia.org/wiki/Axial_tilt section Oscillation. The first section of the term for epsilon is a constant, the “as is” of “as found” value. As far as I know (and my knowledge is limited) there is no Grand Design Order that that number does not budge. In many dynamic system I met that number is or can be arbitrary – a ‘set bias’.

    Last point. What is intended by the term ‘central limit’ I fail to grasp. In fact I’m lost with para5.

  173. oldmanK says:

    PV, I have posted above without realising your latest post. Two quick points. 1) I have discreetly warned of a cultic issue. I suggest ignore that — Wittmann has no such connection. 2) Also ignore Karnak — too many questions there for my liking. Stick purely to those who specifically measured obliquity. However you still get the same answer.

    I was also very wary of the 2345bce date because of the Ussher connection. I have quoted it since because it is one of the firm dates in dendrochronology. Sometimes, as much as I hate it, one has to give the devil his due.

  174. Paul Vaughan says:

    oldmanK, I would say yes we are getting somewhere with this.

    I know what needs to be done to solve this puzzle. Some of the needed steps are firmly beyond my reach presently due to lack of time and resources, but it’s on a list of hard core things I’ll do if I ever get solid, long-term, secure opportunity.

    Meanwhile, as always I’m open to the dead-simple. In a way, being short on time and resources is a blessing as it forces this and prevents getting lost in the culture of sophisticated academic simulation. If there’s something simple to discover on the Pareto Principle, that’s almost certain to be of MORE value than the feedback academics get from their models about their input assumptions!

    More later, but for now 2 things:

    1. A model can account for low variance and still be significant. There can be LOTS of error and the model can still improve odds.

    2. The various models (e.g. Newcomb (1906), Wilkins (1960), Laskar (1986), & Astronomical Almanac (2010)) are NOT dynamical models. They’re just polynomial fits that approximate the long-run SECULAR variability. They’ll ballpark obliquity on-average in the long-run. They don’t necessarily give an exact authoritative value for a SPECIFIC point in time or even over intervals. I need to assert: You’re misinterpreting the model output. Anomalies from the model are informative. They can be used for model refinement. I’m not aware of any resistance to the notion that the obliquity models can be improved in detail. (I think you’re imagining resistance that doesn’t exist.) The models are already fine at coarse scale and you should concede this. (If you take a long-run multivariate view, this will be no problem.)

    We’ll need to slow down the pace of discussion and multi-task. I’ll need to be doing other exploration in parallel and it absolutely cannot take a back seat. I appreciate your patience. Thank you for bringing to the table an interesting puzzle.

    Some of the ideas I have about how to solve this puzzle and what the answer will look like are sure to be very upsetting to some people.

    Huygens synchronization of two clocks
    Henrique M. Oliveira & Luís V. Melo [2015]

    Abstract
    The synchronization of two pendulum clocks hanging from a wall was first observed by Huygens during the XVII century. This type of synchronization is observed in other areas, and is fundamentally different from the problem of two clocks hanging from a moveable base. We present a model explaining the phase opposition synchronization of two pendulum clocks in those conditions. The predicted behaviour is observed experimentally, validating the model.

    http://www.nature.com/articles/srep11548?WT.ec_id=SREP-639-20150728
    Youtube ref: v=SGgbRkix_hY

    From the intro:
    We present a mathematical model where the coupling is assumed to be attained through the exchange of impacts between the oscillators (clocks). This model presents the additional advantage of being independent of the physical nature of the oscillators, and thus can be used in other oscillator systems where synchronization and phase locking has been observed.

It is the tenth lowest maximum extent on record. On average, the maximum occurs much later (September 23 to 24).

    The early maximum appears to be the result of an intense wind pattern in September

    The NSIDC summary says ‘Antarctic ice extent saw a sharp decline during the first half of September’ without mentioning either that it was at a record level at the end of August, or that the winds were unusually strong straight afterwards, disrupting some of the seasonal sea ice build-up. Why would they do that in the summary? The usual alarmist spin no doubt.

    NSIDC sea ice news policy seems to be:
    Record high? – obscure footnote
    Record low? – front page news

    The signature of wind in ocean currents…

    meridional & zonal mean geostrophic velocity:

    On the meridional map, note the opposite pattern at the equator in the Indian Ocean (compared to Pacific & Atlantic) and on either side of Australia (compared to the Americas).
