The Elephant in The Climate Change Space

Categories: Academia, Business, Climate & Weather, Emergency & Disaster, Environment, Science & Technology, Space

The Grand Solar Minimum is a time when The Sun goes into a kind of hibernation, where Planet Earth will not be receiving the heat it normally depends on to carry out most of life’s necessities. Solar Cycles run every 11 years, some have lasted 6 cycles.

Major challenges will be arriving all at once, such as finding, growing, cooking, and storing food. Many of us will be faced with not being able to receive power from the standard electric & gas companies that we totally depend on.

Transportation infrastructure will be affecting supply chains and basic levels of transportation such as buses, trains, and cars. Heating our homes will be imperative!

Dr. Valentina Zharkova, founder of ZVS Research Enterprise Ltd, at Solargsm.com. is a Solar Physicist, Mathematician, Teacher, and professor, who joins us to share her scientific findings about our main star, The Sun.

She shares how and the Suns’ Activity has impacted life in the distant past and why our ability to measure it is so advanced, that we will have a front-row seat at this Earthly Cycle.

This interview is about leaving you with a totally different framework in which to clearly understand the importance of this Solar Cycle & why it’s urgent that we understand how the Sun works, and how measuring it has totally changed over the last 2-300 years. You and your loved ones still have time to prepare for this upcoming Solar Cycle.

It’s advisable to have paper and pen with you so that you don’t miss the key distinctions that you would ordinarily not receive in ordinary climate science data and discussions.

Share this with everyone you know and care about. Don’t miss this Special.

      RAINMAKING TIME:
      I feel that we could be so unaware of what we need to be aware of. Our destiny is vulnerable and very concerning. What is most important is to realize we are the care takers of our world and our lives. We can get prepared to face the truth not thru fear but through creative solutions. What is the TRUTH? How can I HELP?

        Hi Midge,

        Thanks for your concerning comment and offer of help.

        yes, you can help us to spread the word to as many people as possible. May I suggest just to share with other people in your circle this interview, other interviews and materials found on my website https://solargsm.com.

        The Grand Solar Minimum is already here https://www.armstrongeconomics.com/world-news/climate/dark-hole-opens-in-the-sun-we-are-in-a-solar-minimum/. And with every year we will have more and more evidences of its not only on the Sun but also on the Earth. Like people had during Maunder minimum in 17th century…

        We live in the unique historic times because our generation will follow the GSM for the first time in history.. People just need to become ready for these changes..

        With seasonal greetings

    Prof. Zharkova’s statements (see also Zharkova’s website https://solargsm.com):
    “Between cycle 25 and 11 years of cycle 26 [the least active cycle], and between cycle 26 and 27, will be the coldest period on Earth, and we will feel it through a lack of vegetation”. “… starting after the active period during the ‘Solar Cycle 25,’ from the second half of this decade until the early 2050s, Earth will experience exceptional cold, extreme weather, earthquakes, and volcanic eruptions”. “Zharkova … warning that the 2030s will be so cold that it will result in a severe food shortage”
    Such statements by Prof. Zharkova unfortunately is completely unfounded scientifically:
    1. Between cycle 25 and 11 years of cycle 26, and between cycle 26 and 27, WILL NOT BE THE COLDEST PERIOD ON EARTH. The total solar irradiance’s (TSI) deep minimum is expected at 2042(+11), but the beginning of a deep cooling should be expected only in 2070 (+11).
    There is only a correlation between deep variations in climate and solar activity, just as there is between CO2 and climate change. THE INFLUENCE OF PROFOUND CHANGES IN SOLAR ACTIVITY ON CLIMATE IS VERY INSIGNIFICANT, AS IN THE CASE OF CO2.
    2. A deep decrease in the solar magnetic field and solar activity will not lead to a decrease in the Earth’s temperature, similar to what happened during the Maunder minimum in the 17th century, as Zharkova (totally) physically incorrectly claims. She has not physical mechanism. Only bicentennial variations in the total solar irradiance are dictating the climate:
    Abdussamatov H.I. Current long-term negative average annual energy balance of the Earth leads to the new Little Ice Age // Thermal Science. 2015. Vol. 19 (Suppl. 2), S279-S288 (http://dx.doi.org/10.2298/TSCI140902018A); et al.
    “THE CYCLIC OSCILLATIONS OF THE SOLAR ACTIVITY LEVEL which develop along with the oscillations of the radius and radiation flux and which accompany the cyclic oscillations of the whole Sun DO NOT SIGNIFICANTLY AFFECT THE RADIATION FLUX VARIATIONS AND CLIMATIC CHANGES”. (for example, Abdussamatov H.I. Long-term variations of the integral radiation flux and possible temperature changes in the solar core // Kinematics and Physics of Celestial Bodies. 2005. Vol. 21, pp. 328-332; et al.).
    Prof. Zharkova does not take into account many other physical, the Earth’s energy imbalance and climatic factors. Without a physical scientific basis, there is no need to deliberately mislead.
    CLINTEL MANAGEMENT AGREES WITH ME. Climate Intelligence (CLINTEL) is an independent foundation that operates in the fields of climate change and climate policy.

      To everyone who reads this, please note that when people don’t say who they are and hide behind a name like the above, and when you click into that name, it goes nowhere, it feels highly suspect. I approved it being here because, whoever this person is, I want those in the know to be able to respond to it scientifically. This’s a highly charged subject and the imminence of a dire cooling period brought on by The Grand Solar Minimum is bound to upset traditional researchers and Climate Experts in the space.

      Dear Prof. Abdussamatov,

      Before dropping such defamatory and pointless accusations about our research, I would suggest you read our papers and the book chapters. Let me repeat the scientific arguments.

      Solar dynamo and magnetic field.

      Solar activity as solar dynamo in action – included my precious reply abut solar dynamo and solar activity defined from eigen vectors oof solar oscillation proving the validity of our approach. We published 6 papers not he topic, 2 in the Nature group.

      We have shown in 2015 https://www.nature.com/articles/srep15689 that the Sun has to have two layers in each hemisphere, inner and outer where these dynamo waves are generated. Their interference based on the well developed wave theory has shown to have beating effects of these two waves generated in the inner and outer layers. This leads to the grand solar cycles lasting for 330-380 years and grand solar minima between them. This model of the magnetic wave generation based on the solar dynamo theory and wave interaction theory is presented in the paper Zharkova et al, 2015

      The minima of solar activity its between cycles 25 and 26 and then between cycle 26 and 27 will be the periods of coolest periods on earth in the past 300 years, as expected for grand solar minima.

      Whatever Prof. Abdussamatov proposes is aa pure speculations with our any theoretical basis.

      Prof. Abdussamatiov tells a complete nonsense not based on any nodes or observations. He can speculate anything he wants, but we have shown in our paper Zharkova et al, 2023, MNRAS https://solargsm.com/wp-content/uploads/2023/04/zharkova_etal_mnras2023.pdf that our prediction of solar activity in the last 10 cycles coincides with that by sunspots within 67% of accuracy that is the maximum one can get with the magnetic waves produced by dipole magnetic field. Only by adding the waves produced by quadruple, sextuple an octuple field one can get cooler to 99% prediction.

      About temperature variations during the Maunderr minimum, the previous GSM.

      This topic has been described in my book chapter https://www.intechopen.com/chapters/75534 taken from the research by Lean et al, 1995, by Shindell et al, 2001, Science and by other authors cited in the chapter.
      Specifically, I wish to bring your attention to the section 2.1 and Figure 2 showing the variations of solar irradiance and terrestrial temperature during the Maunder Minimum and other minima of solar activity.

      We also provided a table of other estimations of solar irradiance drop during the MM, you can learn some additional information for your research. This is a top plot of Fig. 2 in the chapter, done by Lean et al, 1995.
      Also Steinhilber et al, 2011 shown that the reduction of solar irradiance during the Maunder Minimum reached 3 W/m^2 from 1366 to 1363 W/m^2. As shown in the top plot of Fig.2. This led to the decrease of terrestrial temperature by about 1 C and shown in Fig.2 bottom plot taken fro Easterbrook, 2016.

      The similar conclusions about the decrease of terrestrial temperature has been reported in the Science paper by Shindell et al., 2001, Science, and press releases which can be found here for the temperature variations during the MM for whole planet locations https://earthobservatory.nasa.gov/images/7122/chilly-temperatures-during-the-maunder-minimum.

      Today we have published another paper showing links of temperature and sea level variations from the engine vectors of solar background magnetic field as per link attached https://www.scirp.org/journal/paperinformation.aspx?paperid=129477.

      I would appreciate your apology for defamatory words against respected scientists and a woman with very high credentials in applied mathematics solar plasma physics.

      Also I would recommend you to explore my company webpage https://solargsm.com and especially look at the publications including 4 books and more than 200 scientific papers. Another book is in processing. You can also read a summary of my research in the blog on the webpage https://solargsm.com/the-modern-grand-solar-minimum-2020-2053-versus-global-warming/.

    p.s. CLINTEL does not agree with Abdussamatov as they are not scientists. They asked us with Prof. Abdussamatov to discuss between us. I have the emails confirming this point. So even in this situation Dr. Abdussamative does not tells a truth.

    However, Dr. Abdussamatov has not replied to my email and decided to put his defamatory accusations on the page. This is not acceptable for a respected scientists but it proves that there is Abdussamatov has no arguments to answer to our points.

    Hello Professor Zharkova,

    I believe you mentioned the bad treatment metered out by Macquarie University (Aust), to Professor Murray Salby who was the first person that I came across (years ago) to openly discuss the actual atmospheric physics (or lack of) of climate change. If you are in touch, please pass on my best wishes as he was very depressed the last time we communicated.

    One of the questions asked by Kim, opens questions about the relationship of the earths magnetic field and the suns magnetic field.

    Have you had a look at the Electric Universe theory (https://www.electricuniverse.info/electric-universe-theory/) which is at the heart of the Safire project experiment (https://www.safireproject.com/) that we spoke about previously.

    Having graduated many years ago from the Curtin school of engineering and having studied electrical engineering, the concept makes a lot of sense to me.

    If you can agree with the existence of Birkeland currents (https://www.plasma-universe.com/on-possible-electric-phenomena-in-solar-systems-and-nebulae-by-kristian_birkeland/) flowing through dark plasma that connects all celestial bodies, then it is possible that the sun receives energy from it’s galaxy through the plasma flows and this may vary resulting in the 2000 and 11 year cycle variation that would be caused by this phenomenon. According to the theory, the earth and all the other planets also receive current flows from the sun via polar Birkeland currents. EU theory is heavily explored in the Safire experiment and as I said before, that team could benefit hugely from your mathematics behind the sun frequencies.

  • Valentina Zharkova Dec 13, 2023 @ 6:07

    Dear Paul Cahill,

    Many thanks for your comments.

    Unfortunately, as fas as I know Prof. Salby is no longer with us. This is a big loss for the climate science, I think.

    I like the comment about the Earth currents. I believe this is exactly how the solar magnetic field interacts with the terrestrial magnetic field. We suggested in our paper on the link of volcanic eruptions with solar magnetic field https://solargsm.com/wp-content/uploads/2023/06/vasilieva_zharkova23-Links-of-Terrestrial-Volcanic.pdf this interaction is essential in governing the geomagnetic activity. These magnetic field create norther polar current sheet which initiates the geomagnetic activity. I am not sure about the currents in a dark plasma, to me it looks a bit of black magic. But I will explore the link.

    I fully agree that the Satire project would benefit enourmosly from our data. But they refuse to use them. They refuse to acknowledge that solar irradiance changes over the position of tithe Earth on the orbit. They simply use average over a year that is mathematically incorrect because solar irradiance does not have a normal distribution, so the notation of ‘average’ designed for Normal data, is not applicable to this multivariate data series.

    Very kind regards

    Valentina

    So we now will look at the Satire data and try too investigate them in conjunction with our magnetic data.

    Do you have any comments to what Usoskin and Kovaltsov writes here:

    https://arxiv.org/pdf/1512.05516.pdf

    “A two-wave dynamo model was recently proposed by Zharkova et al.
    (2015, Zh15 henceforth), which aims at long-term predictions of solar ac-
    tivity for millennia ahead and backwards. Here we confront the backward
    predictions for the last 800 years with known variability of solar activ-
    ity, using both direct sunspot observations since 1610 and reconstructions
    based on cosmogenic nuclide data. We show that the Zh15 model fails
    to reproduce the well-established features of the solar activity evolution
    during the last millennium. This means that the predictive part for the
    future is not reliable either ”

    This is a complete nonsense objection, which we already answered in JASTP paper published in 2018 https://solargsm.com/wp-content/uploads/2020/03/zharkova_reply2usoskin_jastp17.pdf and in many other papers(see for example https://solargsm.com/wp-content/uploads/2020/03/zharkova_iau335_paper1.pdf and more recent papers published in 2022-2023 https://solargsm.com/publications.

    First of all, the detection of Grand Solar Cycles and Grand Solar minima occurred from the observations of solar magnetic field. It is not a model but the observational result. We derived the waves oof the own oscillations of solar dynamo waves (called eigen vectors). Only after having this observations we applying the solar dynamo model which allowed to reproduce these observational waves on the timescale of 2000 years. This is for the first time when dynamo models can reproduce the solar activity on such a long timescale.

    We also compared our index of solar activity defined by the solar magnetic field with that using sunspots in the paper Zharkova et al, 2023 published in MNRAS https://solargsm.com/wp-content/uploads/2023/04/zharkova_etal_mnras2023.pdf. It is proven to be a very accurate reproduction of the solar activity.

    Later we extended the detection of solar magnetic waves backwards by 5000 and 120 000 years that allowed to fit the main knows GSM like Homeric solar minimum etc.. This is contrary to the current predictions of solar activity with single dynamo models which can only catch the activity closely only for a single 11 year cycle.

    Thank you so much for your exceptional contributions professor Zharkova. I’m always excited to read / listen to your research. What are your views on the effect of the GSM on the Caribbean islands?
    Many thanks
    JA

    • Valentina Zharkova Dec 31, 2023 @ 16:56

      Since nobody yet observed the GSM, it is rather difficult to be certain. Based on the educated knowledge, knowing the GSM will cause cold jets from the Arctics, I would anticipate that the terrestrial areas mainly affected by the modern GSM will be upper to middle latitudes. Although some effects can reach to subtropics in extreme cases like we have seen in the Eastern hemisphere during the winter of 2018 when the snow and frost reached Spain and Morocco. Although Caribbean islands are much further south, so they might not be affected.

  • So Isiitso Dec 31, 2023 @ 14:08

    Zharkova:

    I have seen in discussion-forum on FB claims that GSM is expected around 2095, with this justification :

    ” The largest grand solar minimum of the Little Ice Age was the Sporer Minimum. Zharkova’s 400 year cycle is at full amplitude then, so she speciously invokes a supernova as a driver for the decades of colder weather.”

    “A cycle of grand solar minima has to be in multiples of the average length of centennial solar minima. That could be 3 at 324 years, or 4 at 431 years, but not 350-400 years as that would fall out of phase with the centennial solar minima!
    The real value is 8 at 863 years, and the next grand solar minimum series begins around 2095. The current centennial minimum will be over by cycle 26.”

    Is it possible to give a comment on the 2095 claimed above?

    It is not my claim, but for ordinary people/laymen it is not easy to understand the processes about the sun, that’s the reason for posting this claim seen in a forum.

    Regards

    Isiitso

  • Valentina Zharkova Dec 31, 2023 @ 17:02

    The claim about the solar minimum expected at 2095 is a complete nonsense not supported by any models or mechanisms.

    Let us start from the beginning. What Zharkova et al, 2015 https://www.nature.com/articles/srep15689 did derive the frequencies and amplitudes of the magnetic waves of the Sun detected from its solar background magnetic field taken from the daily magnetograms. In the wave theory these waves are called natural oscillations of the system with our external forcing. When the external forcing works on the frequency of natural oscillations th system has a resonance and the can bee broken as it has happened to the Tacoma bridge collapse in the US https://en.wikipedia.org/wiki/Tacoma_Narrows_Bridge_(1940) affected by the 50m/h gales inducing the bridge oscillation on its natural frequency and to the Millennium bridge collapse in London https://www.google.com/search?q=millennium+bridge+collapse+video&rlz=1C5CHFA_enGB1086GB1087&oq=Millenial+bridge+collapse&gs_lcrp=EgZjaHJvbWUqCQgCEAAYDRiABDIGCAAQRRg5MgkIARAAGA0YgAQyCQgCEAAYDRiABDIICAMQABgWGB4yDQgEEAAYhgMYgAQYigUyDQgFEAAYhgMYgAQYigUyDQgGEAAYhgMYgAQYigUyDQgHEAAYhgMYgAQYigUyDQgIEAAYhgMYgAQYigXSAQg4NjIyajBqNKgCALACAA&sourceid=chrome&ie=UTF-8 when the walking people induced its torcional oscillations at the natural frequency of the bridge.

    Hence, what we detected is the natural frequencies of solar magnetic waves produced by dipole, quadruple, sextuple and octuple magnetic sources. The eigen veecttos and eeigen valuse detected for these magnetic waves in Zharkova et al, 2015 using the cycles 21-23 as input are confirmed in our recent paper using the cycle 21-24 as an input Zharkova et al,m. 2022, MNRAS https://solargsm.com/wp-content/uploads/2022/04/zharkova_shepherd_mnras22.pdf. This confirms that the magnetic wave parameters remain the same independently from the number of cycles used because they are defined by the internal structure of the Sun and mechanisms of generation of solar dynamo in the solar interior.. In that MNRAS paper of 2022 wee have shown that other waves generated by quadruple, sextuple and octuple magnetic sources are linked to occurrences of solar flare and linked to the SXR index of solar flares. In the paper Zharkova et al, MNRAS 2023 wee demonstrated that our index od solar activity defined by the summary curve of two largest eigen vectors, or solar magnetic dynamo waves produced by dipole magnetic sources (North and South poles) are closets the sunspot solar activity index approaching 67% of correlation. That is a maximum for dipole magnetic sources producing the two largest magnetic waves, or eigen vector which cover about 39% of the data by variance (our eugenics values) or it is 67% of the magnetic field data by standard deviation. Our grand solar cycles and grand solar minima covered very nicely the main GSM reported in the observations: Wolf, Oort, even Homeric one. and these GSM naturally shown during the whole extended simulation of this summary curve as shown in our papers Zharkova et al, 2017 https://arxiv.org/abs/1705.04482, Zharkova et al, 2018 https://solargsm.com/wp-content/uploads/2020/03/zharkova_iau335_paper1.pdf and in later paper published din 2022-2023. In these papers and in the paper answering thee Usoskin objections we specifically explained the non-existent Spoerer minimum which was cause by the change of the terrestrial cosmic array environment induced by the explosion of the Vela Junior supernova occurred only 600 light years from the Solar system, If the supernova was close by 100 light years, the life on Erath would seized to exist. What has happened that the time of Carbon isotope detection using Libby’s method, was changed try 200-300 years, because they relate the abundance of carbon isotopes to the background of terrestrial atmosphere using a standard background while they should use the enhanced background induced by this supernova, which is still produced very strong Gamma rays 800 years later..

    One can see the grand solar cycles (GSCs) and GSMs between them are repeated regularly every 2100 years having 5 GSCs with the similar shapes. We explained these GSC occurrences veery naturally by the constructive interference of two magnetic waves produced by the solar dynamo inside the solar interior in two different layers (bottom and top). Again, the resulting wave amplitudes and frequencies follow the wave theory and can be clearly explained.. The first modern GSM is happening now (2020-2053), or cycles 25-27, the next one will happen in 2375-2415.

    Whoever produces the different results, do not use any theories but just create aa mess for laymans who do not have the expertise to understand the PCA in action and the wave theory for these wave interaction. I saw Prof. Abdussamatov placed a comment above which I answered. He suggested that the Sun will have the GSM for 200 years starting from 2010 without giving any reasons or any mechanisms which can produce it. It is like an astrology, which is not a scientific approach.

    I cannot find any reason of possible reduction of solar activity in 2095 besides by adding the quadruple waves and obtaining the Gleizberg centennial cycle as we also explained din our MNRAS paper Zharkova et al, 2022. The last minimum of this centennial cycle was in cycle 24, so by any calculations one can obtain the next one about that time of 2095-2100. But.. The amplitudes of the GSM and Gleisberg cycles are different, the GSM amplitudes are much smaller that Gleisberg cycles, as we saw in thee Maunder minimum and in the current modern minimum where the amplitude of cycle 26 will be 70$ lower that that of cycles 25 or 24.

    Any speculations about the durations of GSCs are baseless as wee have shown, that these cycles, each of them have different durations and amplitudes depending where they occur during the 2-millennial period. The duration of GSC varies from 400 to 320 years. These are the results we derived from the observations of full disk solar magnetic field, these are the real eigen vectors (magnetic waves) of solar dynamo, similar to the EM waves generated by electrons moving about protons in hydrogen atoms, which parameters are described by Shroedinger equation.
