NASA: Earth’s magnetic poles are ‘switching’ with catastrophic consequences for humanity. The Earth could be left powerless to defend against blasts of solar radiation from the Sun for up to 200 YEARS, leaving us at risk from skin cancer and worldwide electronic communication blackouts, NASA scientists have warned. The US space agency confirmed fears that we may be heading towards an extraordinary event, which would see compasses point SOUTH if the magnetic poles shift.
Climate researchers believe we are heading towards a reversal of the planet’s magnetic field, an event that has happened before and has been attributed to wiping out the Neanderthal species. Bruce Jakosky, MAVEN principal investigator at the University of Colorado, Boulder, said when the switch does take place, the Earth’s magnetic field which prevents the Sun’s dangerous radiation getting through, would be neutralised for around 200 years. He revealed the detail during an historic announcement about how Mars lost 99% of its atmosphere and its oceans that could have housed early life. Mr Jakosky explained that Mars had been blasted by solar winds, which had stripped it of its atmosphere, for billions of years since the beginnings of our solar system. He said: “When the polar shift happens the Earth will have no magnetic field for about 200 years.” During that time the Sun’s solar blasts are expected to strip away at our atmosphere as they did on Mars billions of years ago. But he thankfully added that 200 years would not be long enough for the Sun to significantly reduce the atmosphere for life to die out. […]
The magnetic shield is our first line of defence against harmful UV rays, and any thinning of the atmosphere could increase the risk from skin cancer. Without a magnetic field, or with a significantly reduced one it could destroy global communications facilities, power supplies, and even lead to fires and rioting on the streets, according to some researchers.

Geologists have said the shift event has happened a number of times in Earth’s history - with the last one 780,000 years ago during the stone age. Alan Thompson, head of geomagnetism at the British Geological Survey, said during previous flips: “no worldwide shifting of continents or other planet-wide disasters occurred, as geoscientists can testify to from fossil and other records.” Earthquakes aside, there is a scientific belief that as we head towards a reversal - which could be less than 1,000 years away, Earth’s magnetic field will dangerously weaken leaving us at the mercy of solar storms when radiation and X-rays are ejected from the Sun towards our planet.

Ho letto altri documenti scientifici che dicevano specificamente che il prossimo “polar shift” è in ritardo, sarebbe già dovuto avvenire.
It is caused by patches of iron atoms in our liquid outer core getting reverse-aligned, as if they were small magnets oriented in the opposite direction to others around them. If reversed ions expand to the stage they out power the others, the Earth’s overall magnetic field “flips”. Jean-Pierre Valet, who conducts research on geomagnetic reversals at the Institute of Earth Physics of Paris, said: “The most dramatic changes that occur when the poles reverse is a very large decrease of the total field intensity.” Monika Korte, the scientific director of the Niemegk Geomagnetic Observatory at GFZ Potsdam in Germany, said: "It’s not a sudden flip, but a slow process, during which the field strength becomes weak, very probably the field becomes more complex and might show more than two poles for a while, and then builds up in strength and [aligns] in the opposite direction. "When the magnetic field gets weakest, as ours should continue to do so, is when we are at most risk from solar flares.
Ho letto anche che basterebbe una guerra nucleare per anticipare il meccanismo in quanto le esplosioni nucleari creano confusione nelle particelle di ferro. Gli effetti sulle tecnologie digitali sono gravi: la morte per la maggior parte dei nostri smartphone, computer e televisori… come? Attraverso pulsi elettromagnetici – sia indotti appositamente attraverso una esplosione nucleare o attraverso l’assenza dello schermo magnetico planetare, sono in grado di causare cortocircuiti in tutte le schede elettroniche. Lo dimostra una scena nel film “The Day After” quando si spengono tutte le automobili e la gente deve continuare a piedi. Un film eccellente per comprendere le potenzialità della guerra nucleare, by the way.
John Tarduno, professor of geophysics at the University of Rochester, said: "Coronal mass ejections (CMEs) occasionally occur on the Sun, and sometimes hurtle directly toward Earth. “Some of the particles associated with CMEs can be blocked by Earth’s magnetic field. With a weak field, this shielding is less efficient.” Other experts aren’t convinced that there’s a connection between pole reversals and species extinctions. “Even if the field becomes very weak, at the Earth’s surface we are shielded from radiation by the atmosphere. Similarly as we cannot see or feel the presence of the geomagnetic field now, we most likely would not notice any significant change from a reversal,” Ms Korte said.
One thing is clear though another flip WILL happen at some stage and our magnetic field has already weakened. It is believed a growing patch of reverse-alignment in the liquid core beneath Brazil and the South Atlantic is responsible. Mr Tarduno said: "(It) has been decreasing for at least 160 years at an alarming rate, leading some to speculate that we are heading toward a reversal."
