    Professor Valentina Zharkova Breaks Her Silence and CONFIRMS "Super" Grand Solar Minimum - Electroverse http://electroverse.net/professor-valentina-zharkova-breaks-her-silence-and-confirms-super-grand-solar-minimum/?fbclid=IwAR2ylLAQY7aDxVLD0EDsf8k8jPPBMD2z2ueN6p5-zcSJAvIxJjGnzVqctnU

    Not wanting to bring politics in this, I just wanted to bring this to folk's attention. There's a somewhat lengthy presentation video at the link that explains the idea but I'll try to summarize some of the points.

    The woman in question, Valentina Zharkova, is a physicist studying the sun. She and her colleagues -- while working on observed data -- hit on the idea of sustained waves oscillating across the sun and as these did or did not interact several things seemed to concurrently happen: such as the appearance of sunspots or the reversal of the sun's magnetic poles. She describes the sun's oscillations as very regular, saying it indicates our star is likely in good health.

    The first version of this idea, with two waves IIRC, managed to coincide very closely with historical data except for the Maraunder Minimum. But then other physicists provided measurements showing that there were such wave systems in adjacent outer layers of the sun. With a four wave model the projected results did match historical or data from things like tree rings, for both the Maraunder Minimum and things like the Roman Warm Period.

    She noted that among well over a hundred different attempts to model solar cycle 24, the one we're presently in, only two, including hers, predicted that the cycle would be weaker than solar cycle 23.

    Essentially, the progress and interaction of these wave systems is being presented as a valid indicator for solar weather much as sun spots are. Only these are more predictable.

    Oh, and based on her models, which again are able to match known history (a rarity when compared to geocentered climate models) would seem to indicate that we are on the cusp of another Grand Solar Minimum that will take us well through perihelion where closest coincided with most possible exposure for the northern hemisphere and likewise winter even less ... which would otherwise result in warmer summers in the northern hemisphere (and colder winters ... so not all good news if you hate hot summers).

    Some years ago a Canadian at another forum humorously demanded who he should sue for the global warming he was promised. If we really are heading into a Grand Minimum we may hear more of that.

    Sigh. You will be disappointed to hear that the Grand Minimum will result in about .25% degrees on average lower temperature, but the effects will be varied.
    Even in the "Little Ice Age", at the last Solar minimum, there was warming in other parts of the world.

    Its going to be hugely offset by the Global Warming of the CO2 levels.
    Our Sun’s becoming cooler than it has been for 400 years https://www.news.com.au/technology/science/space/our-sun-is-about-to-get-unusually-cool-researchers-predict/news-story/dea38cc09657428b5d6f4dbd97b8d97b

    We are such small blips on the acale of these changes, I prefer to say, hmm, interesting and give it little xtra thought. My comment means I have already gone too far and simply don't want to rise outta bed.
