The Weakening Of Earth’s Magnetic Field Has Greatly Accelerated

Posted: April 14, 2019 by oldbrew in Electro-magnetism, Measurement, solar system dynamics

Earth’s magnetic field keeps weakening at a faster rate. Should we be concerned?

The Next Grand Minimum

Earth’s magnetic field is getting significantly weaker, the magnetic north pole is shifting at an accelerating pace, and scientists readily admit that a sudden pole shift could potentially cause “trillions of dollars” in damage. Today, most of us take the protection provided by Earth’s magnetic field completely for granted. It is essentially a colossal force field which surrounds our planet and makes life possible. And even with such protection, a giant solar storm could still potentially hit our planet and completely fry our power grid. But as our magnetic field continues to get weaker and weaker, even much smaller solar storms will have the potential to be cataclysmic. And once the magnetic field gets weak enough, we will be facing much bigger problems. As you will see below, if enough solar radiation starts reaching our planet none of us will survive.
But now we are being told that data collected…

    “The magnetic field is constantly changing,” said Susan McLean, the retired chief of the geophysical sciences division at NOAA, who helped set the magnetic model in the past. “It changes with time. It changes with location. And it changes the way it changes.” Tracking the planetary magnetic field, she added, is more akin to forecasting the weather.

    So as the Earth’s magnetic domain diminishes we are more open to a solar storm, or CME flare, wrecking all of our precious electronics, and all the many everyday processes that rely on them.
    I wonder what contingencies are in place for that probable (but hopefully not soon) likelihood?

    Earth’s magnetic field is acting up and geologists don’t know why

    Erratic motion of north magnetic pole forces experts to update model that aids global navigation.

    In the mid-1990s it picked up speed, from around 15 kilometres per year to around 55 kilometres per year.

    Canada is essentially losing a magnetic tug-of-war with Siberia.

    What utter nonsense, our ancestors, animals and plants survived all the other magnetic collapses and ensuing pole reversals. Basic logic suggests that this fear mongering is wild speculation since we, the animal kingdom and plants are here to tell the tale. Yes, there will be more radiation reaching the surface, however, by logical deduction it is the dense atmosphere that really (primarily) protects all life, the magnetic shield is an added (temporary) layer of protection that periodically declines.

    No, we all won’t die of radiation sickness or cancer, our bodies have a built in repair mechanism for radiation damage similar to an immune response to disease. The process is called hormesis, at low levels of radiation the body’s cell damage repair process kicks in. As the magnetic shield declines, the body’s natural defenses gear up in response to the ever increasing radiation. So cancel the apocalypse.

    Ann Coulter did a nice article on radiation years ago debunking the wild false assertions of econut liberals who are against all things nuclear.


    This only seems counterintuitive because of media hysteria for the past 20 years trying to convince Americans that radiation at any dose is bad. There is, however, burgeoning evidence that excess radiation operates as a sort of cancer vaccine.

    As The New York Times science section reported in 2001, an increasing number of scientists believe that at some level — much higher than the minimums set by the U.S. government — radiation is good for you. “They theorize,” the Times said, that “these doses protect against cancer by activating cells’ natural defense mechanisms.”

    Among the studies mentioned by the Times was one in Canada finding that tuberculosis patients subjected to multiple chest X-rays had much lower rates of breast cancer than the general population…

    …Although it is hardly a settled scientific fact that excess radiation is a health benefit, there’s certainly evidence that it decreases the risk of some cancers — and there are plenty of scientists willing to say so. But Jenny McCarthy’s vaccine theories get more press than Harvard physics professors’ studies on the potential benefits of radiation.

    Two things which I thought should have changed while in college back 40 years to offset the consequences of a dormant sun;

    a) start building more underground residential structures. The advantages are plethora
    b) replace the aging power plants with distributed systems. Smart power came into the industry in the 80s and synching is no longer the problem it once was. The waste heat of independent power could be used to great advantage in municipal, educative, medical, and even residential installations.

    One of the largest of problems is reliance on satellite systems that have no technological backup.

    The Earth does not have a single magnetic field. It has many, that together, average out into the overall field. As the strength of local granules field change, due to shifts in energy circulations below , the above field orientation shifts. As the magnetic field of Eastern Siberia strengthens and the Scandinavian one weakens the apparent magnetic north moves. To the south a similar condition exists as the far south Atlantic Anomaly strengthens.
    This Polar field reversal demonstrated in Geological record, may well be local events as these local fields migrate…pg

    Recent Acceleration of the North Magnetic Pole Linked to Magnetic Jerks (2002)

    Assuming a continued velocity of 40 km/yr, the NMP will pass beyond the 2000-nautical-mile limit of Canada in 2005; it will make its closest approach to the geographic pole (88.8°, 180°E) in 2024, and it will reach the Siberian island of Severnya Zemlya by mid-century.

    But the velocity is still increasing.

    Earth’s magnetic north pole is moving too fast for experts to keep up. Now scientists might know why.
