The Earth has a hot core that creates a magnetic field that can protect our planet from destructive solar winds. This magnetic field is vital for all living things on Earth, but over the past 200 years it has weakened by 15 percent. The field is a shield from harmful solar radiation and extends thousands of kilometers into space, and its magnetism affects everything from global communication systems to power systems.
Before, the North and South magnetic poles of the Earth turned over every 200 or 300 thousand years. And the fact that the last change of poles occurred about 780 thousand years ago, means that this process is late. The latest data received from the European Space Agency’s Swarm satellites, which track the Earth’s magnetic field, may indicate that the change is imminent. Satellites allow you to study the changes occurring in the core of the Earth, from where the magnetic field begins. Observations of the researchers indicate that molten iron and nickel draw energy from the core of the Earth, which creates a magnetic field. Although scientists are not sure why this is happening, they describe it as “disturbing activity”, which suggests that the magnetic field is preparing for a change of poles.
An international group of scientific experts compared the current state of the Earth’s magnetic field to the conditions during the Lachamp event (about 41,400 years ago) and the events of Lake Mono (about 34,000 years ago). In both of these cases, the Earth’s magnetic field “recovered”, and the change of poles did not occur, and scientists believe that it will be the same now.
“There are suggestions that the inversion of the magnetic poles or displacement is approaching us,” says team member Richard Holm of the University of Liverpool of the United Kingdom. “However, after studying the last two displacements, we showed that none of them resembles the current changes in the geomagnetic field, and therefore, we believe that such an event is unlikely to occur. On the contrary, our study suggests that a weakened magnetic field will recover without extreme consequences, and therefore it is unlikely to invert the poles. ”
In his new report, Daniel Baker, who is the director of the Laboratory of Atmospheric and Space Physics at the University of Colorado in Boulder, argues that if an inversion of the magnetic poles occurs, this is likely to make some areas of the planet “unfit for habitation” due to the disconnection of electricity systems.
Humanity will survive the inversion of the poles, but it can cause serious problems for satellites, communication systems and electric power. There is also a possibility that this will affect the temperature and climate of the planet, but scientists are simply not yet sure what the consequences will be, since, in the end, the last complete change of poles occurred 780 thousand years ago. But you can believe them when they say that there will not be any shortages in the electricity network due to pole inversion in the near future …
