Scientists predict: the Earth's poles at any time can change places. Will there be a global catastrophe?

American experts from Johns Hopkins University (USA) recently scared: there's coming a change of magnetic poles. This conclusion they did after he found out that in the earth's core happen chaotic processes. One side of the solid inner core (the other part of the kernel - external and liquid.) The earth is slowly growing, while the other slowly melts.

- Such a one-sided growth of the earth's core can provoke a quick shift of the magnetic North pole to the East, and eventually the North and the South will be swapped, - predicts study author Peter Olson. - Moving magnetic field was confirmed by satellite data. When will the planetary cataclysm - I do not know. Chaos in the kernel prevent them from making long-term forecasts.

But his colleagues from other countries more categorical. Employees of the Paris Institute of Earth are convinced that the reverse will happen in 100 years. And Danish scientists from the Danish research Institute of space waiting for this for over 40 years. And paint a picture of this Apocalypse.

Our planet is waiting for the fate of Mars?

Here's the "little" troubles that carries the reshuffle: will fail navigation and electronic machinery and poultry and fish are lost in space.

And the worst climate change. The ozone layer will become thinner or disappear altogether. On the planet from space will fall solar radiation, usually deny magnetic shields. And the weather will become unpredictable. Winter will become more severe, summer - sessilee. Heavy rains, floods will create a threat of flood. Earthquakes will paralizat face of the planet. All our life will be threatened.

- Judging by the fossil remains of animals and plants, for the last 540 million years during perepelyak surge occurs in the evolution of the biosphere and kill most living organisms, - said Renault finally from the Johns Hopkins University (USA). - It is possible that as a result of such castling just killed the dinosaurs.

There are also fantastic hypotheses.

- In the result of change of magnetic poles of the Earth died Atlantis and other civilization that once inhabited the planet, say geologists William Ryan and Walter Pitman from Columbia University. And even Mars became deserted, because the polarity disappeared magnetic field, which, in turn, led to the volatilization of the atmosphere on the red planet.

Inside is a powerful magnet

Surely we are waiting for the fate of Mars? For comments we turned to the Deputy Director of the Institute for Earth physics. O. Y. Schmidt, RAS, doctor of technical Sciences Vyacheslav Konakovo.

- Vyacheslav Nikolaevich, in fact we are facing a planetary catastrophe?

"I think not, " said us Professor. - For all history of the Earth's magnetic poles changed places several times. And here she is alive. And we, too. A change of magnetic poles is the usual story of the existence of magnetic fields on the planet.

- And how soon they can change places?

- The mantle of the Earth, which creates at movement of the magnetic field of the planet is moving very slowly (it's very massive). Besides, it is able to change both the speed and direction of movement. And this movement does not depend on the geographical axis of rotation of the planet (magnetic pole and geographical pole are not the same, their deviation from each other is 7 degrees. - Ed.). Due to their size and weight mantle quickly their movement cannot be changed. This is how powerful truck, which is not able to turn around 180 degrees at full speed. And you think that after 40 or 100 years poles change places? Complete nonsense!

- And affects our "truck" anomalous behavior of the kernel?

This theory has the right to life for a simple reason: inside the planet core consists of two fractions - is the liquid part of the core is solid. Solid himself the center of the planet. And anomaly in the Central part of the kernel, which consists of pure metals, iron, for example, in some way affects the Earth's magnetic field. But the kernel does not create a magnetic field and, therefore, does not affect the polarity reversal.

- Good, but if not a hundred years, and a thousand magnetic poles have changed places, what will happen?

- Nothing! Here you arrived in Australia, where the shadow is falling to the North and South. You touched? Also, when and the compass needle will show in the other direction, anyone from this change is neither hot nor cold. Over the last billion years of the current magnetic North pole started the movement in Northern Australia, walked across the Pacific ocean to the position of our geographic pole, and now is in the opposite direction. So what? The main thing is that the magnetic field has been preserved. Because it protects humanity from hard radiation of space.

- Half a century ago, the North magnetic pole was moving at a speed of 10 km per year in the early 2000s - 40 km per year. Now run faster?

- Yes, its rate has increased slightly.

- And the climate is not because of the polarity changing? And then the weather is very alarming: floods, storms, heat exorbitant.

- The Earth's magnetic field affects the climate, but not significantly. For example, in its spectrum are manifested cycles - secular or 11 years. But mankind has always lived under these cycles quietly.
