Weakening Sun triggered a Little Ice Age 2,800 years ago

Weakening Sun triggered a Little Ice Age 2,800 years ago

Caused distinct climate change in less than a decade – and the same could happen again soon. This could throw global warming predictions out of whack.


After studying 2,800-year-old core samples from a European lake, an international team of scientists found that weakening solar activity sparked an abrupt period of cooling that lasted for about 200 years. (They didn’t label it a “Little Ice Age,” but I think we’ll eventually learn that that is what it was.)

The scientists, under the direction of the Geo Research Potsdam (GFZ), refer to the cooling period as the ‘Homeric Minimum,’  because that’s when the Greek poet Homer was writing The Odyssey.

Meteorologist Anthony Watts posted a graph showing variations in the sun’s magnetic field for the past the 10,00 years, which I am showing below. The graph shows the Homeric Minimum. Click here to see a larger view.

Writing in the journal Nature Geoscience, the researchers also state the rather obvious fact that colder periods bring crop failures, war, starvation, bitter cold and heavy rains, and that the sun is an important factor in human activity. (You’d think we should welcome global warming, wouldn’t you?)

What are frequently regarded as minor variations in solar radiation, at least regionally, can produce significant climatic effects and have far-reaching consequences, the scientists found.

As activity on the sun, and particularly the UV component of light, temporarily plummeted, it disturbed the heat budget of the middle atmosphere and the ozone layer, thereby altering the jet stream and air flow over the Arctic. The climate of the northern hemisphere abruptly turned cool, windy and rainy, especially in the winter.

Analyzing sediments in Lake Meerfelder Maar, Germany, from 3,300 to 2,000 years before present, the scientists discovered a sharp increase in windiness and cosmogenic 10Be deposition some 2,759  years ago. From this, they inferred that atmospheric circulation had reacted abruptly and in phase with the solar minimum. Beryllium 10 is always formed in the rock when it is exposed to radiation, they said.

No surprise. I point out in Not by Fire but by Ice that spikes in beryllium 10 occur in sync with the ice-age cycle. (p 198-199)

The sediments, called varves, contain important climatic information from the past. Somewhat like annual tree rings, “varves consist of a bright, spring-deposited layer from the shells of diatoms and a dark, in the remainder of the accumulated layer,” the researchers explain.

Prior to 2760 years ago, the thickness of the varves suddenly doubled, within just eight years.

This discovery corresponds well with the 1440-year cooling cycle that I discuss in Not by Fire but by Ice. (p 218).

“The 1440-year cycle brings with it ‘dramatic and rapid’ changes in climate and worldwide glacier expansion…,” I wrote, “which I attribute to underwater volcanism, triggered by changes in geomagnetic intensity, triggered by changes in the sun.”

“So here we sit,” I continued. “The next beat of the 179-year solar retrograde cycle is due. The next beat of the 360-year Little Ice Age cycle is due. The next beat of the 1440-year ice-age cycle is die. The next beat of the 100,000-year ice-age cycle is due . . . and we’re worried about global warming?”

Here we sit, with more and more proof that we’re headed into an ice age, while the U.S. government does everything in its power to shut down energy production.

You’d almost think that our leaders have a vendetta against humans.

No, that’s not possible.

Is it?

  1. An important paper – and its remarkable that a study predicting cooling made it into a high profile journal.

  2. You said –
    You’d almost think that our leaders have a vendetta against humans.

    No, that’s not possible.

    I say, why isn’t it possible? I’ve said right along that the purpose of driving global warming into the brain of the dimly informed is to get them to accept the drops in land used for food, and the power from coal. Then, let mother nature freeze their testicles off, or let them fight to the death over table scraps. “They” don’t care about people other than themselves. Yes, my friend, our bleeders, er, leaders, DO have a vendetta against those humans classified as “useless eaters,” which, unfortunately, includes about 80% of “us.”

    • Tom O I think your percentage may be a little low. From what I have seen and heard on the the internet the hoped for kill rate may equal or exceed 95%.
      The Georgia Guide stones reqire that the population be maintained at no more than half a billion. We are at 7 billion therefore 13 out of 14 must perish.
      Nasty bunch running the show wouldn’t you say? I am expecting the elites and their servants to boldly claim that excess CO2 on earth causes the sun to go into a solar minimum. Not that such a hypothesis has any credibility but because they are looking for a justification to tax and regulate us all to death. When you boil it all down we are up against an elite clique of satanists and their stooges.

      • “I am expecting the elites and their servants to boldly claim that excess CO2 on earth causes the sun to go into a solar minimum” LOL!
        Yeah, and they will ask NASA to say that! 🙂

    • Robert was being sarcastic:-)
      anyone with an ounce of nous sees the anti humanity vibe being raised yet again by the Eugenicists who are also conveniently the green lobby- it melds so well -save the planet kill the excess humans ie as the kari kritter and gore and Ehrlich and Maurice strong suzuki et al all espouse.
      spend Billions on useless warmist shite while cutting health hospital and other serious things like power water and land use, by using greenbrush strokes to make that seem more important to the sheepies who refuse to wake up.

  3. Thank God for you robert… You have the only theory that stands up to all the other theories I have seen and heard…Look at the obviuos things that are happenning around the world. Dolphines and whales dying off, birds crashing into the ground and dying, and mass fish kills. Sounds like the magnetic field strenth of earth is finally crossing the line from protective to the not protitive realm. I hope we can make it through what looks like is coming…

  4. Good keep it up! Theres more if one looks for it Im sure. Im more convincedthan ever the enture solar activity is driven by the Solar barycenter oscillation caused by the orbits of the gas giant planets. Just need a model tying the observation. The Sun is an average yellow type star about halfway along the main sequence (HR diagram) the core is stable over long terms but the outer shells and field can be modulated.

    • Interesting I also read about this but although we do have a bary-centre oscillation on our sun, it surely can’t last long enough to cause a cold period for say 60 years? Or can it? Or perhaps our sun’s binary companion can have an effect?
      Whatever the cause, it is getting colder and I am so glad I am in the southern hemisphere!!!

      • If you live in the southern hemisphere, how can you say it’s getting colder? We could certainly use some cooling down here in southeast Texas… We just experienced the warmest April in 50 years and it’s already 90 and above here in May. And like several of us living down here have already pointed out, this is happening after having no winter at all! We’re going to have another scorcher of a summer and I’m certainly not looking forward to it!!!!

        • My fault Theo, I wasn’t thinking straight when I read southern hemisphere. You probably live in Australia and when first reading your post all I saw was southern. Sorry bout that.

      • THe 60 years can be related to the moon (according to Piers C). The lunar nodal presession has a 58 years component about 3 times the presession 18 1/3 years.

  5. Because of some rather unscientific read readings in late 1940s and more, but more scientific readings beginning later and continuing to the present I have come to believe that a very serious cold period is due. In fact some harbingers of the coming situation have become quite prominent in the last several years in the American southwest where I live. The (short) summer seasons have warmer and the winters longer and colder. I believe this (theses) cycle will continue and increase, perhaps this year. I suggested this year (2012-2013) would at least we the kickoff if not the complete ball game.
    What can we do about it? We can’t stop it. We will have to learn to live with it. I would suggest either of Robert Felix’s two books. Better, read them both and every thing else you can find and start putting together survival tools including food.
    And, yes, I may be an alarmist. I certainly hope so.

  7. All the pertinent solar cycles including the 100000 years cycles are lining up and meanwhile Obama fiddles as we slide headlong into the next ice age without the necessary energy needed to deal with this clear and present danger. We’re going to beg for some global warming to get us through and the warmists are going to become a byword to be despised by all for their deception.

  8. Once more, as elsewhere said:

    “I am getting bored. The globe can be getting warmer or colder, but the idea that the human contribution from burning carbon fuels has anything to do with it is not only IMHO the biggest political and intellectual fraud ever – but so says the IPCC itself: http://cleanenergypundit.blogspot.com/2011/10/west-is-facing-new-severe-recession.html. The ongoing discussion pro and con is becoming akin to the scholastic argument as to how many angels can dance on the head of a needle. Which is, of course, exactly what is intended, to achieve worldwide disorientation away from the actual IPCC aims of their monetary and energy policies – and bringing a whole, if not all, of science into disrepute. Even the UK Royal Society has become Lysenkoist.”

    That’s not to belittle the effort by thousands of scientists fighting for the truth in climate research, but I dismay over the practical effect of diverting all this brain power in a direction not at all relevant to the IPCC’s actual and declared political and financial intentions.

    All in IMHO, of course. My musings for what they may be worth on my various blogsite entries, and at http://www.lmhdesign.co.uk/sustainability.php

  9. I remembered from some weeks passed that Eifel suffered some tremors as had the whole region and the lake is in the caldera. Therefore quite recent record of the suns cooling. Following quote from Wiki……’Just like the nearby ‘Wehrer Kessel’ volcano and Rieden volcano, the Laacher See volcano forms a volcanic caldera in the Eifel mountain range. It is part of the area called “East Eifel volcanic field”.’

  10. Not unlike the pharaohs of yesteryear, our leaders are stiff necked and arrogant, choosing to believe the soothsayers and purveyors of false science, rather than the Joseph’s among us (such as Robert, our moderator).
    Foolishly, in the years of plenty we have chosen to burn our food as fuel, rather than to take advantage of the plentiful crops supported by the temporary warming. We have no stockpiles.
    We will soon regret this action.
    Our planet has sustained us, with the Sun as its warmer and not so warmer, for millenia. It provides all the fuel we need at relatively little cost for the benefits gained, and we spurn that which stares us in the eye.
    Replacing our natural food varieties with manufactured genetic models will prove to be our ruin when the pests and diseases learn to master our feeble efforts. look to the super-bug now coming out of India as an example.
    Stock up my friends. it will be a long and very cold winter.
    PS- see the movie “Idiocracy”

  11. When my wife linked to this on her Facebook site, someone said that there were no other ice cores that confirmed the number and gave a link to CO2 science. Knowing that the Vostok data is readily available I took a look at noaa.gove and found an interesting pattern (if I am reading it right):

    79 2501 -436.2 0.30
    80 2542 -439.6 -0.27
    81 2585 -446.2 -1.36
    82 2628 -439 -0.17
    83 2670 -438.1 -0.02
    84 2713 -445.2 -1.19
    85 2760 -449.9 -1.97
    86 2805 -441.7 -0.61
    87 2847 -434.5 0.58

    If I’m reading this correctly this shows a marked drop in temperature with a minimum at 2760 years ago (which is the lowest point until 11,749 when it was -2.20 warming up from much lower. Someone who knows what they are doing should take a closer look at this.

    • Thanks for the very interesting link. Seems a long discussion there, I could not read it entirely yet.
      The following is also my feeling
      “… So, I predict that, depending on what this upcoming minimum turns out to be, will determine whether or not we’re going into a simple cool period as seen in the 1970’s/1900’s, or whether it will be a steady, significant cooling, followed by a plunge into conditions that the system will not recover from, hence the end of the Holocene… ”
      The Holocene is about to end, it could be now or it could stretch for a few more decades, but due to the strength of the last “grand cooling” of the Maunder minimum (which seems what we’re heading into again) and the very strong 6 solar cycles that preceded the present one, the end of this interglacial seems to knocking at our doors.

      • here is another similar comment:
        “… We’re coming off the highest grand maximum in solar activity in over 9000yrs, which took place right after the coldest period in the Holocene (the LIA), which was a huge perturbation on its own, so immediately after this historic grand maximum we plunge into another Manuder-style minimum, I can’t see how the Holocene interglacial could be maintained with another shutdown of the solar cycle …”
        (link: http://www.westernusawx.info/forums/index.php?showtopic=33725&st=0&p=585303&#entry585303)
        I believe these oscillations are also cyclical and the fact that they’re happening now is the precise indication that the Holocene is about to end.
        It’s not just a random perturbation, it’s a precise indication of what comes next.

    • This should be my last post about this, but more and more interesting comments this guy, called “Modern Day Galileo”, has.

      /1/ This first one you’ll probably agree Robert, although I still think we can circumvent it,
      “… It’d be [the new Ice Age] pretty [awful] for developing and 3rd world nations, which is why it makes me so sick to see the direction climate science is going right now… all politics, no science anymore.
      A true ice age could be enough to wipe out the human race altogether in a matter of a century or two… and it is going to happen again very soon whether or not we continue to emit [gigatons] of CO2 into the atmosphere … ” (my italics)

      /2/ regarding the magnetic field
      “… First we need to realize that the energy from the solar wind that interacts with the magnetic field, perturbing the climate … circulation systems does NOT ‘disappear’… it is NOT ‘deflected’, that is not what magnetism does!
      And they [warmists] actually know it! Some of the charged particles will deflect but the interactive process that occurs via terrestrial molecules is transferred through the climate system … depending on the orientation of the … interplanetary magnetic field.

      Remember the solar wind is striking the Earth’s upper atmosphere at usually more than 1 million miles per hour, and it is an electrically charged ‘wind’, containing more energy than the ‘winds’ in our atmosphere at the same speed by over 5000X during the interactive perturbational process!
      A mere 20km/sec change in the solar wind … when translated into radiative value…. and depending on the orientation of the … interplanetary magnetic field, will determine whether 8W/m^2 or 12W/m^2 of that ends up being processed through the climate system…it’s huge…”

      /3/ about the climate in general:
      “… The Magnetic interactive process drives ENSO, the AMO, PDO, IOD, SOI, AAM, Global Temps, Arctic Circulation regimes that affect Sea Ice, etc…
      EVERYTHING that we have.
      We have disrespected the Sun, the very reason we’re here…and we are about to pay for it big time…”

      The last phrase is very sensible IMO.
      (link: http://www.westernusawx.info/forums/index.php?s=3a3947bac3e3b0a60ad94a79b3b063d4&showtopic=33725&view=findpost&p=587579)

  12. While I think it likely that we are in for a cooling period of perhaps 2 or 3 solar cycles, there were other events that could have caused the cooling of ~2800 yrs ago.
    This was a period that civilizations with thousands of years records of celestial events that used a 360 day year and 30 day moon in China, the Middle East and Central and South America gave up their old recording systems and recalibrated them with what agrees with to-days numbers
    There was a period of close encounters with planets at this time with world wide catastrophes and records of the Sun “standing still for three days” and “rising in the East”.
    See http://www.scribd.com/isissolaris/d/21746049-Velikovsky-Worlds-in-Collision
    starting at page 187, it has references for these ancient records too.

  13. “… the researchers also state the rather obvious fact that colder periods bring crop failures, war, starvation… ”
    I’d rather say the obvious fact that the lack of preparedness for colder periods may bring many inconveniences, but if you’re prepared you can enjoy the beauty and wisdom of Mother Nature either in winters or summers.
    People’s minds cause problems, not the climate.

  14. Ian Kellman says: “… it will be a long and very cold winter… ”
    That’s the correct analogy IMO. That’s what we (very probably) will be facing in the next few decades.
    The full force of the Ice Age takes many centuries to happen.
    Even if it start within a few years, it’s still not “a few days” and we do have some time to prepare.
    The thing we must keep in our minds IMO is that all these cycles are just natural phenomena and we, humans, have already gone through them in past, then there is no good reason that we’ll not make it again.
    We grew so much during the challenging times of the last century, they are not necessarily a bad thing.

  15. Piers Corbyn has been spot on about this May in the UK, the way he was in December 2010.The BBC have been using the snow symbols for Scotland most of the month and night minima have been nearing record levels. He of course uses a solar/lunar methodology to make his predictions and his longer term ones are very much in line with Robert’s. The first sign for us in Scotland will be permanent snow beds in the Mamore hills surrounding Ben Nevis.
