David Evans devises solar model to tame climate chaos

Jo Nova and David Evans reveal astounding new work

Will this be the magic bullet to destroy climate ignorance?

This from Jo Nova (note her lack of arrogance):

Behind the scenes, for 18 months, Dr David Evans (my other half) has been quietly working full time on climate research. The Fourier expert with six degrees who studied at Stanford has discovered something extraordinary using silicon-chip maths on the climate system. (Electrical engineers are really going to like this new approach.) This is real science laid bare. He has produced a new solar climate model that can explain the modern warming using mostly solar and natural factors. Thus CO2 could be a minor influence. Has he found the mystery factor that the other climate models miss? Watch one well-trained passionate expert pursue a creative idea that breaks the current paradigm. Over the next week we’ll be setting the theory free in post after post for everyone to test and review.

As they say, bring your popcorn. Get ready to concentrate.

BIG NEWS Part I: Historic development — New Solar climate model coming

Read about what has been going on behind the scenes and the background to this new approach. This work — should it stand the test of time — will be held up as an example of where independent research can succeed over the grand failure of expensive government-funded and bureaucratically-driven science. Christopher Monckton calls it “a devastating new approach to the climate question.”

BIG NEWS Part II: For the first time – a mysterious notch filter found in the climate

We start putting our cards on the table. We’re announcing the entirely new discovery of something called a notch filter in the climate. There are notch filters at home in electronic equipment, but everyone seems to have missed the largest notch filter running on the planet — and it’s an 11-year cycle. How significant?!

Looking for the short cut? Skip to Figures 5 and 6 for the most important action. Look at the spike down at 11 years. Figure 6 was the moment when Bob Carter sat up dead straight in his chair. The same mysterious effect happens in all the datasets .

A special thank you to all the people who have supported us over the years and make independent science possible.

Cheers from Jo!

I love their approach of open publication rather than peer-review. It’s very courageous, like learning to play the violin on a public street corner. They will be vilified and jeered at, but science will win in the end. It is not cloistered in government-funded academia (behind a paywall) but open for all to see. The comments on Jo’s site are fascinating. Apart from one or two heckling trolls, not one warmist has said anything of substance. Yet these two articles have generated a wealth of in-depth discussion by PhDs and learned gents like Willis and Monckton. It’s wonderful to see such open and honest science, even if my limited education only allows for 10% understanding. I will be following the rolling out of this breakthrough with the same intensity that I followed Climategate 1. Am making a special trip to Countdown to ensure their popcorn stocks are up to it.

Re open publication rather than peer-review, I think Jo has been paving the way for this e.g. ‘Failure of Peer Review, meaningless statistical significance, needs fixing says Doctor & journal’ http://joannenova.com.au/2014/06/failure-of-peer-review-meaningless-statistical-significance-needs-fixing-says-doctor-journal/ And, ‘Newton, Einstein, Watson and Crick, were not peer reviewed’ http://joannenova.com.au/2014/05/newton-einstein-watson-and-crick-were-not-peer-reviewed/ I note that the anthropogenic global warming hypothesis has never even been documented in a definitive sense by anyone to allow proof or falsification — let alone peer reviewed and published. PSI has utilized open publication for a while now and very useful in an era of rapid communication, response, and correction to hypotheses without politically correct filtering by “peers”. We’ll see this at JoNova too. Lets not forget though, that David Evans is only really doing what many others like the Pangburn’s, Wilde’s, Scafetta’s, and Abdussamatovs have done in both published and unpublished spheres – advance an alternative climate hypothesis or model for public consideration i.e. there are others similar e.g. ‘On the Dynamics of Global Temperature’ Authors: David R.B. Stockwell In this alternative theory of global temperature dynamics over the annual to the glacial time scales, the accumulation of variations in solar irradiance dominates the dynamics of global temperature… Read more »

From my comment under the previous post where Mike first pointed to the Evans model: I assume David is not including the ocean in “the planet” for this comment [quoted at link below] and that he’s just referring to atmospheric heat in some way (i.e. a sun => atm system in 11 yr cycle terms). I’ll wait for the next post (Part III) to see the details of that. In Part II, “Let’s build that solar model”, he says: “We are envisaging some sort of black box, whose input is TSI and whose output is temperature.” 5 years planetary heat storage (decade max) [see Evans quote] would be at odds with just about everyone else thermodynamically if he is referring to a sun => ocean => atm system where heat storage is obviously the ocean and much much longer than 5 years (i.e. 11 yr solar cycles aren’t the driver of planetary heat). https://www.climateconversation.org.nz/2014/06/wind-and-waves-scatter-sea-ice-not-agw/#comment-838755 From Part II comments: bananabender #11 June 15, 2014 at 9:17 pm “The Sun does not heat the atmosphere directly.

I didn’t think the Fourier option applicable to climate. I noticed guys like Tim Channon at Tallbloke’s using it to find cycles, so they seemed to have that covered quite competently.

Then David Stockwell talked me into looking for a low pass filter, in October 2012. He had done some initial analysis that showed there was a low pass filter in the solar signal, so I thought I would poke around and try to find the transfer function. Found the notch instead, and that turned out to be the key, as we shall see…

I’d like to “bookmark” the following comment below from Part II (a reply to Willis Eschenbach by MSimon) because it’s a concise translation of what we are addressing (to my mind), what to look to in Part III, IV, V, etc, and touches on the fascinating aspect of it (to some of us but not to Willis obviously) yet to be disclosed. That aspect for me is that, although solar-centric, I’ve not been at all interested in the 11 Yr cycle as being of any relevance to long-term climate even though warmists fixate on it as being what they think of as the basis of the AGW-sceptic solar-centric case when it’s not (or hasn’t been – it may have to be included depending on whether what Evans presents stacks up). To my mind the basis of a solar-centric case is the bicentennial component of solar intensity (a line tracing 11 yr cycle solar intensity minimums) and what MSimon describes below as “Multi – 11 year cycles”. But now I’m obliged to consider what might be 11 yr solar cycle climate system processes I’d not bothered to get into previously because that would be… Read more »

‘Obama’s Climate McCarthyism Demeans Presidential Office’

President Barack Obama demeaned the dignity of the presidency by ridiculing tens of thousands of scientists for simply disagreeing with his lay opinions on global warming. While the political left throws shrill temper tantrums against anybody who “disrespects” the Office of the Presidency by asking Barack Obama a challenging question (something they had no qualms about during the Bush administration), Obama himself is setting the applicable ground rules for disrespectful political discourse and climate McCarthyism.

BIG NEWS part IV: A huge leap understanding the mysterious 11 year solar delay

The model does not explain why there has been an increase in temperature over the past 100 years.
The notch filter is created to explain why there is no peak in temperature related to change in TSI. A more rational explanation is that the solar variation (approx 0.1%) is insufficiently large to be detected over natural variation.
Part IV is a hoot. A mysterious ‘Force X’ caused by the flipping of the sun’s polarity. Good stuff.

>”To my mind the basis of a solar-centric case is the bicentennial component of solar intensity (a line tracing 11 yr cycle solar intensity minimums)”

Abdussamatov has documented this more than anyone else. Interesting that minimums (or minima) are used, not an average or integral. This effectively negates the peaks (maximums, or maxima) over multiple 11 yr cycles.

Now here we are looking for some mechanism (“Force X”, Part IV) that may actually negate peak 11 yr solar intensity as an energy input to climate. I don’t recall why exactly the bicentennial component traces minima specifically, nor whether Abdussamatov addressed a mechanism that negates the maxima as an energy input to the planetary system. Time for a re-read of Abdussamatov.

Fascinating.

>”The model does not explain why there has been an increase in temperature over the past 100 years” Stay with it Simon. The system being laid out progressively is only dealing with an 11 yr cycle so far. Once that’s developed and everyone is up to speed then I think we’ll be moving to multi-11 year cycles which obviously span solar output over the last 100 years as introduced in Part II. The highest solar output occurred between about 1950 and 2009 with the peak at 1986. The key as I see it is as MSimon upthread “The 11 year cycle does not show up in the temperature record. Multi – 11 year cycles (which have a lower frequency component) do” But until the single cycle phenomena is understood by all in this exercise it’s pointless moving on to a multi-11 year system. And note that this is primarily a system analysis exercise rather than a physical mechanism identification exercise. But as Part IV shows (brought forward due to so much interest in the physical mechanism), system leads to mechanism. >”The notch filter is created to explain…….” No. The notch filter is self-evident… Read more »

>”Part IV is a hoot. A mysterious ‘Force X’ caused by the flipping of the sun’s polarity. Good stuff.” But on earth what? Evans in Part IV: “We will soon deduce from the solar model that the notch and the delay work by affecting the albedo of the Earth (the fraction of solar radiation that is reflected straight back out to space by clouds, snow, ice etc. without warming the Earth, about 30%). We will also find by looking at the proportional changes in solar radiation and albedo that over the last few decades that the effect on temperature of albedo modulation has been at least six times greater than the immediate heating effect of variation in solar radiation. So it appears the notch and delay are associated with a powerful indirect solar influence that modulates the Earth’s albedo.” http://joannenova.com.au/2014/06/big-news-part-iv-a-huge-leap-understanding-the-mysterious-11-year-solar-delay/ >”We will soon deduce from the solar model…………………….that the effect on temperature of albedo modulation has been at least six times greater than the immediate heating effect of variation in solar radiation” Get your contra-arguments ready for that Simon.

Evans: “It is important not to prejudge what this influence is, so let us call this influence “force X” for now” “The obvious candidate for force X is some aspect of the solar magnetic field that is responsible for deflecting cosmic rays……..” “It is possible that force X is not related to cosmic rays. For instance force X might be electric and modulate the ozone in the Earth’s stratosphere, or otherwise affect the Earth’s atmosphere by some electrical connection.” “Force X has ten to twenty times more influence on temperatures on Earth than changes in the direct heating effect of TSI (a result we will show later).” “I know that “force X” sounds speculative, but this is where the trail has taken us. We observed the notch, deduced the delay, and the 11 year clock leads us to the Sun. We find some confirmation in the synchronicity of the peaks in TSI with the troughs in the Sun’s magnetic field, so force X has something to do… Read more »

Simon, you’re aware that at the crossover point occurring at peak 11 yr TSI, the sun’s magnetic field strength decreases to zero?

That’s non-trivial surely?

>”….solar variation (approx 0.1%) is insufficiently large to be detected over natural variation” That is in respect to one solar cycle and around 0.8 W/m2, also in respect to SCs 18 – 23 rather than 24. Some merit in that on the face of it I agree but not according to SB implication and low noise OFT which is what we have in front of us now and a notch filter to consider. But over SCs 18 – 23 there was little difference SC to SC i.e. a constantly high solar output higher than for about 11,000 years (the Modern Grand Maximum – see below). That’s all changed with SC 24 which is markedly weaker relative to the previous six. So we have a multi-11 year cycle timeframe from which to compare to other similar timeframes e.g. the last Grand Minimum (Maunder). According to Shapiro et al the variation between Maunder Grand Minimum and Modern Grand Maximum could be as much as 6 W/m2 which is easily sufficiently large to be detected over natural variation in temperature datasets. This is the real solar variation worth consideration in regard to temperature, one cycle by… Read more »

For reference from Part IV,

Figure 1: When sunspot activity peaks, solar radiation is at a maximum but the solar magnetic field is at its weakest because it is reversing polarity. (This figure merely illustrates the timing; the solar polar field is but one aspect of the Sun’s magnetic field, and it is not proposed that this is force X.)

Lubos:

“What the near-vanishing of R~(f) for 1/f close to 11 years really means is that the most obvious possible proof of the direct effect of the total solar irradiance doesn’t exist – the 11-year cycle isn’t present in the temperature data. This is a problem – potentially a huge problem – for any theory that tries to present the solar output as the primary driver even at the decadal scale and faster scales. It’s surely nothing to boast about”

Not a problem at all, just reality and everyone knows the 11 year cycle isn’t present in temperature anyway. But why? Lubos preempts Part IV.

What we’ve still yet to be shown is what happens in the multi-11 year cycle timeframe, say the TSI step from the early 20th C ending 1930ish to the Modern Grand Maximum (MGM) starting 1950ish i.e. to SCs 18 – 23.

I don’t see David Evans claiming the 11 yr cycle is the primary driver — on the contrary in fact as I understand so far.

‘The long sunspot cycle 23 predicts a significant temperature decrease in cycle 24’ Jan-Erik Solheim, Kjell Stordahl, Ole Humlum, DOI: 10.1016/j.jastp.2012.02.008 Abstract Relations between the length of a sunspot cycle and the average temperature in the same and the next cycle are calculated for a number of meteorological stations in Norway and in the North Atlantic region. No significant trend is found between the length of a cycle and the average temperature in the same cycle, but a significant negative trend is found between the length of a cycle and the temperature in the next cycle. This provides a tool to predict an average temperature decrease of at least View the MathML source from solar cycle 23 to solar cycle 24 for the stations and areas analyzed. We find for the Norwegian local stations investigated that 25–56% of the temperature increase the last 150 years may be attributed to the Sun. For 3 North Atlantic stations we get 63–72% solar contribution. This points to the Atlantic currents as reinforcing a solar signal.

Richard C (NZ)

Richard C (NZ)

>”the actual make up of the energy” Exactly. Energy-per-photon increases from IR-B to IR-A to Visible to UV-A to UV-B. i.e. along the EM spectrum and yes, the changes in UV are dramatic, much moreso than IR. Then there’s the material that the energy strikes where the energy is converted to heat or not depending on mutual “tuning” and varying penetration (“path length”) and photosythesis. But TSI becomes the simplified proxy for all of that because it is easier to handle (sunspots are another proxy for solar activity – see below). That’s without even beginning to look at magnetic flux interactions. However I don’t think magnetism necessarily needs to be invoked to counteract a notch as David and Joanne have. I think they’ve just used tools, techniques, and datasets for analysis that lead to that. I’ve pointed out at JoNova that there is a body of literature that does identify the 11 yr cycle response using different tools, techniques and datasets in the troposphere, sea surface, and stratosphere. I still want to see the rest of David’s model development because the notch issue may be insignificant once multiple consecutive solar cycles are covered… Read more »

‘The global warming hiatus? Climate models all wrongly predicted warming, so let’s call it a discrepancy’

Ross McKitrick, Special to Financial Post | June 16, 2014 |

“The IPCC briefly discussed the seriousness of the model-observation discrepancy in Chapter 9 of the 2013 report. It reports that over the 1998-2012 interval 111 out of 114 climate model runs over-predicted warming, achieving thereby, as it were, a 97% consensus.”

State-of-play synopsis:

[McKitrick] – “According to the IPCC, estimated “radiative forcing” of greenhouse gases (the term it uses to describe the expected heating effect) increased by 43% after 2005.”

[McKitrick] – “To the extent climate models overstate the effects of CO2, so do IAMs, thereby yielding exaggerated estimates of the social cost of carbon emissions and overly stringent policy prescriptions.”

[von Storch] – “If things continue as they have been, in five years, at the latest, we will need to acknowledge that something is fundamentally wrong with our climate models.”

[Curry] – “If the 20-year threshold is reached for the pause, this will lead inescapably to the conclusion that the climate model sensitivity to CO2 is too large.”

[McKitrick] – “We will reach the 20 year mark with no trend in the satellite data at the end of 2015, and in the surface data at the end of 2017. With CO2 levels continuing to rise, it will at that point be impossible to reconcile climate models with reality and the mainstream consensus on how the climate system responds to greenhouse gases will begin breaking apart.”

‘Scientist Reveals Inconvenient Truth to Alarmists’ By Larry Bell Dr. Christian Schluchter’s discovery of 4,000-year-old chunks of wood at the leading edge of a Swiss glacier was clearly not cheered by many members of the global warming doom-and-gloom science orthodoxy. This finding indicated that the Alps were pretty nearly glacier-free at that time, disproving accepted theories that they only began retreating after the end of the little ice age in the mid-19th century. As he concluded, the region had once been much warmer than today, with “a wild landscape and wide flowing river.” […] Schluchter criticizes his critics for focusing on a time period which is “indeed too short.” His studies and analyses of a Rhone glacier area reveal that “the rock surface had [previously] been ice-free 5,800 of the last 10,000 years.” Such changes can occur very rapidly. His research team was stunned to find trunks of huge trees near the edge of Mont Mine Glacier which had all died in just a single year. They determined that time to be 8,200 years ago based upon oxygen isotopes in the Greenland ice which showed marked cooling. Casting serious doubt upon alarmist U.N.-IPCC… Read more »

If if was apparent it would show up in localized data as Barlyaeva has analysed and only where the locality allows (forget CET for example), but I don’t think she has proved anything conclusive.

Correction. Solar flux is measured by F10.7 index above – not W/m2.

Refer the latest update graph:

http://www.solen.info/solar/

Solar flux is measured by the 10.7cm Solar Radio Flux index in this case, defined as:

The F10.7 index is a measure of the noise level generated by the sun at a wavelength of 10.7 cm at the earth’s orbit. The global daily value of this index is measured at local noon at the Pentictin Radio Observatory in Canada. Historically, this index has been used as an input to ionospheric models as a surrogate for the solar output in wavelengths that produce photoionization in the earth’s ionosphere (in the ultraviolet bands).

http://www.nwra.com/spawx/f10.html

A proxy for solar-at-surface too (measured at surface) so the difference of SC 23 peak to SC 24 by F10.7 is still an indication of the relative activity.

SC 24 peak 27% weaker than SC 23 peak on monthly average of F10.7.

No departure from anything known already. >”The step response of the delayed path” Fine again, the “slow” response path. Out to 15 years, entirely consistent with anyone else who has calculated a planetary delay (land+ocean) by other techniques e.g. stats, thermo principles. Abdussamatov calculates 14 +/- 6 years by thermodynamic principles, Scafetta 12 years by stats, Trenberth 6, and 10+ years out to 100 years oceanic delay simply by observation I think. To name some. But then, apparently, slow response “is due to force X”. Slow response (without the notch) is simply due to the thermal characteristics of surface material i.e. thermal inertia of: ocean (mainly), land, lakes, rivers, rocks, sand, soil, grasslands, vegetation, foliage etc and human modification of all that. So the model is thermally conventional up to this point despite the introduction of the term “Force X” to describe the entire slow response which to me is fallacious. The only departure from convention is the notch (requiring Force… Read more »

Coughlin and K. K. Tung (2004) Abstract [1] A statistically significant atmospheric signal, which represents the influence of solar radiation changes on our climate, is found in global data (1958–2003). Using a nonlinear, nonstationary time series analysis, called empirical mode decomposition, it is shown that atmospheric temperatures and geopotential heights are composed of five global oscillations and a trend. The fourth mode is synchronized with the 11-year solar flux almost everywhere in the lower atmosphere.

Hi Richard, The Sun causes the Diurnal Bulge of the atmosphere as it passes over. This is not necessarily caused by direct heating of the air. In any case the extra heat is almost immediately converted to outward expansion of the atmosphere which results in little or no overall warming. [It is a basic physical chemistry principle that an unconfined gas, such as the atmosphere, cannot be heated because it simply expands to compensate.] Everyone seems to be forgetting that heat=work. They confuse ‘temperature’ (radiation wavelength) and ‘heat’ (kinetic energy of atoms). If you measured the temperature of the Top OF Atmosphere (TOA) it would be be extremely ‘hot’. If you measured the heat with a well shielded mercury thermometer it would be ‘zero’ because there are no atoms to conduct heat. The problem with using a radiative physics approach is that it completely ignores the fact that virtually all of the incoming radiation is converted to work (wind, rain, waves etc) within the dual fluids (air and water) of the ocean/atmosphere system. The energy that escapes the Earth could be visualised as a tiny amount of radiative ‘leakage’ from the outermost surface… Read more »

>”Although the influence of the 11-year TSI peaks cannot be found in the global surface air temperature record (HadCrut, UAH, etc)”

That is because there is no such thing as the “11 year cycle”. That is simply a term of convention due to the long-term average length of 11.2 years.

I’ve replied to the last comment in Part II (Willis) with the the reasoning (recent actual SC lengths etc) here:

That comment then refers back to this Part VI thread where the relevant papers are current (#33.3).

Those papers show how, if you discard the spurious notion of an “11 yr cycle”, warming at the SC peaks when they actually occur is clearly identifiable.

At least we got that sorted out.

I contend that over the short term the notch is a spurious observation based on: wrong premise, wrong analysis tools, and wrong datasets.

Wrong premise? The “11 year cycle” is a term of convention but that is not what it actually is – a recurring phenomenon of varying period.

Richard C (NZ) #33.5.1.1 June 22, 2014 at 1:36 pm Re #33.5.1 >”On the contrary, warming is observed at the SC peaks when they actually occur” I should point out that Coughlin & Tung and Zhou & Tung identify the very faint and very minor “fast” temperature response (immediate TSI path in David’s terms) to SC peaks. But the major response is “slow” and delayed by thermal inertia of the surface heat sinks. The delay is months, years, decades, and even centuries. To relate the delay to current climate the delay can be described as a thermal lag around a dozen years (I prefer 14 by Abdussamatov) plus or minus several years. So the major temperature response to solar change is “smeared” over a very long period and impossible to detect as a spike in temperature records except the difference between Grand Min and Grand Max (H/t Griss): http://therionorteline.files.wordpress.com/2012/08/2000-years-of-global-temperaturessp.jpg For example, the Modern solar Grand Maximum (a series of SCs) peaked in 1986.

Evans model prediction in David Archibald article in American Thinker here (H/t Andrew @ JN): http://americanthinker.com/2014/06/a_cold_dawn_coming.html I don’t find that scenario plausible but we’ll know by 2017 whether it’s valid or not. I think David’s “clock” delay (based on spurious observation and fixation on the minor “fast” response IMO) produces a temperature response far too soon and far too abruptly. Yes historically, there is evidence of abrupt temperature falls when solar activity becomes relatively weak (the IPCC’s Mike Lockwood acknowledges this) but this is a radical fall. If the delay was derived by thermodynamic principles, the major “slow” delay is over a range of years and decades but concentrated on 14 years +/- 6 years (by Abdussamatov’s calc) i.e. the effect of solar conditions in December 2001 (SC 23 peak) has yet to experienced to its fullest extent (2001/12 + 14 = end of 2015 + 6 = 2021). That peak was at near Grand Maximum levels of 1986. The “slow” effect of the relatively weaker SC peak February 2014 wont be experienced until 2028 +/- 6 yrs = 2022 to 2034.

Bernie again #71.2.1 David – I do appreciate that you respond, but you need to consider that you have this wrong. I think it makes significant differences. Further, doing it right probably not only corrects an error, but also simplifies the results. (1) I did no calculations, so there is no assumption about phase. Mine was an EXPERIMENT – components on a bench. Independently, the website I found DID do the calculation, and agreed with my experiment. In as much as the notch is just the sum of a LP and HP (with same poles), the notch step response is the sum of their step responses, widely published, and easy to sum. (2) I assumed you were familiar with filters, but it appears you are not. Butterworth CAN be low-pass but it can also be band-pass, high-pass, or notch. Butterworth refers not to the “type” but rather to the damping “characteristic”, the reciprocal of “Q”. Butterworth Q (for second order) is 1/sqrt(2). Your Fig. 2 response looks to my eye to be Q=1/2. (3) You said “Even if the causality argument was wrong, the delay works and is independently corroborated.” Well – if… Read more »

Mikky #85 June 24, 2014 at 3:25 am David, I think there is too much speculation going on, based on false conclusions from your data analysis: 1. The data analysis does not establish a notch, just an absence of 11-year signal. You would have to see a dip in the SPECTRUM of the temperature data to establish a notch, and there is no such dip? Absence of 11-year signal could probably have mundane explanations, for example averaging due to thermal inertia. 2. A notch filter does not require a time delay, unless you choose to implement it non-causally, which is not necessary. To me, the notch filter is just the method you have used to remove the 11-year signal from the TSI data, leaving the long-term variations. You could have used instead a flat 11-year average, which I suspect would give similar results. Assuming that there is a good correlation (with WOW factor?) between temperature and notched-and-scaled TSI data, then you can determine (roughly) the time delay between those 2 time series, giving you interesting scientific results without any theoretical speculations, and something with predictive power. The reason(s) for the absence of 11-year… Read more »

June 23, 2014 at 10:49 am

>”observed the outputs” (crosspatch #72.1)

That’s the problem I have with David’s rationale.

1) A false premise that there is an actual “11 year solar cycle” based on average length, not actual length of each recurrence of the phenomenon.

2) A very incomplete understanding of the major “slow” thermal delay and response vs the minor “fast” response he looks for as a result of 1) and this incomplete understanding in 2).

3) From 1) and 2), a false assumption that 11 year periodicity “should” be observed in temperature at a significant level (also a false premise).

4) Then, even in the narrow and spurious scope of the minor “fast” response, he uses inappropriate analysis tools and datasets thereby missing the weak “pulse” in temperature at SC peaks due to the fast response when other analysts using different tools, datasets, and not constrained by a fixed period of 11 years DO find the solar signal in the minor fast response of temperature.

‘Laughing Stock Met Office…2007 “Peer-Reviewed” Global Temperature Forecast A Staggering Failure’

By P Gosselin on 24. Juni 2014

Frank Bosse at Die kalte Sonne here puts the spotlight on a global warming forecast published by some British MetOffice scientists in 2007. It appeared in Science here.

The peer-reviewed paper was authored by Doug M. Smith and colleagues under the title: “Improved Surface Temperature Prediction for the Coming Decade from a Global Climate Model“.

[…]

Now that 2007 is some years behind us, even Smith et al have realized their forecast was overinflated and so they produced a new paper which appeared last year. The latest by Smith has taken natural variability more into account and he is much more careful with prophecy-making. Still, the range of uncertainty the new paper offers makes it “more or less useless”

[…]

We’ll be revisiting Smith’s newest forecast in about 5 years time. In the meantime we have to ask ourselves if these people will ever learn. Science can take only so much damage.

Weiss http://notrickszone.com/2013/12/03/german-scientists-show-climate-driven-by-natural-cycles-global-temperature-to-drop-to-1870-levels-by-2100/ We reported recently about our spectral analysis work of European temperatures [1] which shows that during the last centuries all climate changes were caused by periodic (i.e. natural) processes. Non-periodic processes like a warming through the monotonic increase of CO2 in the atmosphere could cause at most 0.1° to 0.2° warming for a doubling of the CO2 content, as it is expected for 2100. Fig. 1 (Fig. 6 of [1] ) shows the measured temperatures (blue) and the temperatures reconstructed using the 6 strongest frequency components (red) of the Fourier spectrum, indicating that the temperature history is determined by periodic processes only. On sees from Fig. 1 that two cycles of periods 200+ years and ~65 years dominate the climate changes, the 200+ year cycle causing the largest part of the temperature increase since 1870. The ~65 year cycle is the well-known, much studied, and well understood “Atlantic/Pacific oscillation” (AMO/PDO). It can be traced back for 1400 years. The AMO/PDO has no external forcing it is “intrinsic dynamics”, an “oscillator”. Although the spectral analysis of the historical… Read more »

Evans model prediction in David Archibald article in Quadrant Online here (H/t Griss @ JN):

https://quadrant.org.au/opinion/doomed-planet/2014/06/edge-cold-deep-abyss/

Same article as American Thinker.

1) Evans N-D prediction turns down in 2014 (I don’t think so – still might though).
2) He has an 11 year solar-temperature lag (I don’t think so – 14 years).
3) He neglects OHC because he says a low-pass filter accounts for it (I don’t think so based on upper ocean OHC peak).

Add another 3 years to his initial 11 to give a 14 year solar-atmosphere lag. Then add about another 4 years (based on UKMO EN3 upper OHC peak 2004) or another 14 years (based on NODC upper OHC peak 2014) lag to 14 year solar-temperature lag (1986-2000) and you’ve got a competing prediction.

That is: solar => ocean => atmosphere system, solar peak 1986, solar peak range 1960 – 2000.

Lag to when temperature turns down based on UKMO OHC
1986 + 14 = 2000 + 14 = 2014 + 4 = 2018

Lag to when temperature turns down based on NODC OHC
1986 + 14 = 2000 + 14 = 2014 + 14 = 2028

We’ll see what’s right by 2018.

Part VIII: New solar theory predicts imminent global cooling

My response #56:

http://joannenova.com.au/2014/06/big-news-viii-new-solar-model-predicts-imminent-global-cooling/#comment-1496889

The model doesn’t capture the thermal damping effect of ocean heat accumulated over the last 100 years or so. Therefore the predicted fall is too soon and too steep – but there will be a fall.

Time will tell on the shape profile and timing of the fall of course.

There is a solar-temperature lag and a model built on that basis is on the right track. The lag is thermal inertia of planetary materials and transport/transfer of heat. The largest heat sink is the ocean so the system is basically sun => ocean => atmosphere.

An 11 year lag goes some way to mimic the transfer of solar energy to air temperature but it’s not enough and development of the 11 yr N-D has not been compelling right from Part II.

There are at least 4 papers documenting 11 yr periodicity in surface and tropospheric temperature including GISTEMP i.e. David not finding it doesn’t mean others haven’t. See Part VII here (troposphere and local surface China):

>”…is the Goddard/Watts adjustment saga the same (similar) thing that NIWA was taken to task on here?” No. NZCSC may have a different answer to mine of course (but probably “no” too I’m sure) but the raw data for NZT7, however you compile it , is available in CliFlo and complete except for the odd missing data. The dispute is over adjustment methodology to the raw data. In the US, closed USHCN stations are still generating estimated data, among other things. This, on the face of it, is incompetence or just inattention. But it has been working out conveniently, hence the suspicion. BTW, Anthony Watts has been on the wrong side of this by a long shot: “…..the best thing about all this hoopla over the USHCN data set is the Polifact story where we have all these experts lined up (including me as the token skeptic) that stated without a doubt that Goddard was wrong and rated the claim “pants of fire”.

‘The Cause Of Earth’s Climate Change Is The Sun’ THE FINGERPRINT OF THE SUN IS ON EARTH’S 160 YEAR TEMPERATURE RECORD, CONTRADICTING IPCC CONCLUSIONS, FINGERPRINTING, & AGW. by Jeffrey A. Glassman, PhD April 2010 ABSTRACT Solar energy as modeled over the last three centuries contains patterns that match the full 160 year instrument record of Earth’s surface temperature. Earth’s surface temperature throughout the modern record is given by Equation (1) where Sn is the increase in Total Solar Irradiance (TSI) measured as the running percentage rise in the trend at every instance in time, t, for the previous n years. The parameters are best fits with the values m134=18.33ºC/%, m46=-3.68ºC/%, b=13.57(-0.43)ºC, and τ=6 years. The value of b in parenthesis gives T(t) as a temperature anomaly. One standard deviation of the error between the equation and the HadCRUT3 data is 0.11ºC (about one ordinate interval). Values for a good approximation (σ=0.13ºC) with a single solar running trend are m134=17.50ºC/%, m46=0, b=13.55(-0.45)ºC, and τ=10 years. V. CONCLUSIONS C. SIGNAL SELECTION & AMPLIFICATION.

And various volleys thereafter, including a good hit from Monckton. Svalgaard still goes on about “900 days of fabricated data”, despite clear and repeated variations on this quote from Joanne (emphasis mine):

The largely irrelevant 3 dots are clearly listed on the graphs as an “assumed average” extension. They have no impact on the model (they are not used in it). They have little impact on the graph (except to make the fall slightly less dramatic by indicating it is ending).

>”The largely irrelevant 3 dots” And the largely irrelevant and ill-directed fixation on smoothed data (noted by others also), thereby missing when the solar step change actually occurred. I tried to communicate that in this post thread around this comment: http://joannenova.com.au/2014/07/the-solar-model-finds-a-big-fall-in-tsi-data-that-few-seem-to-know-about/#comment-1500802 Synopsis: The sudden drop came around 2006.5 according to PMOD TSI (and all the other solar metrics e.g. magnetic, radio. as a few others note): http://www.woodfortrees.org/plot/pmod/from:2005/to:2008 1365.5 down to 1365.33. Now compare 1365.33 2007 level to SC 22 minimum 1365.5 1996-1997: http://www.woodfortrees.org/plot/pmod/from:1995/to:1997.5 1365.33 2007 is off that chart. 2005 1365.5 drop to 2007 1365.33 = 0.17 W/m2. We can put 0.17 W/m2 solar forcing 2005 – 2007 in context using the IPCC’s formula dF = 5.35 ln(C/Co) and ML CO2 data. I’m not suggesting the IPCC’s RF methodology is valid (it isn’t) but the exercise is instructive. ML CO2 ftp://aftp.cmdl.noaa.gov/products/trends/co2/co2_annmean_mlo.txt 2000 369.52 2010 389.85 dF = 5.35 ln(389.85/369.52) Opposing forcings wrt warming: dF CO2: +0.29 W/m2 2000 – 2010 df SUN: -0.17 W/m2 2005 – 2007 This is what it is all about. In the space of one year (2006) solar forcing achieved an offsetting forcing 59% of CO2 forcing for the… Read more »

Jo/David’s graph of smoothed TSI (“big fall in TSI data” post) implies a TSI drop of about, say, 0.25 W/m2 from 2003 to end of SC 23 2008/9:

But their next graph of unsmoothed TSI shows the 0.25 W/m2 drop occurred from 2005 to 2008/9. 0.17 of that occurred in 2006 alone.

Given the TSI drop in the unsmoothed data that many knew about before the N-D model came along (the IPCC’s solar guy Mike Lockwood certainly knows for instance), I find Jo’s post title ‘The Solar Model finds a big fall in TSI data that few seem to know about’ a tad self-serving and alienating. I do recognize that the post is directed at Leif and Willis however.

Maybe the title should read ‘The Solar [data shows] a big fall in TSI [ ] that [a] few seem [not] to know about’.

Forgot the link to the graph, which is:
