Scientists have found indications that the magnetic poles of our planet are on the way to drastically change their position, which could, in turn, have catastrophic consequences for the planet.
But, are things really that bad? Or is it just that some scientists love to panic?
According to the director of the Laboratory of Space and Atmospheric Physics of the University of Colorado (USA), Daniel Baker, Earth's magnetic fields have weakened by 15% in the last 200 years, which could be a sign of that the North Pole and the South Pole are close to exchange positions.
According to the scientist, the effects of a phenomenon of this magnitude could include extensive holes in the ozone layer and massive blackouts.
In addition, many newspaper agencies have warned how areas of the planet would become uninhabitable.
This theory has been reflected in a study carried out by the researcher Alanna Mitchell, published by the British newspaper Daily Mail, which warns of the dangers posed by solar particles and ultraviolet B rays that enter the Earth through of the damaged ozone layer.
Mitchell argues that if this reversal happens, it is likely to render some areas of the planet 'uninhabitable' by knocking out power grids.
His comments were made in an in-depth Undark report written by Alanna Mitchell, who has a new book about the topic titled 'The Spinning Magnet: The Electromagnetic Force that Created the Modern World and Could Destroy It',
Mitchell writes: 'The dangers: devastating streams of particles from the sun, galactic cosmic rays, and enhanced ultraviolet B rays from a radiation-damaged ozone layer, to name just a few of the invisible forces that could harm or kill living creatures.'
These observations reveal that the deep layers are segregating molten iron and nickel, which could mean that the reversal of the poles is imminent.
Scientist Jim Wild explains that if a shift occurs in the Earth's magnetic fields, they would be weakened for centuries and leave the planet exposed to the myriad of harmful radiations from outer space pace.
However, while this may seem like a doomsday scenario propagated by media, the truth is that No... we aren't doomed by the flip.
The truth is that throughout the long history of our planet, Earth's magnetic poles have reversed—causing the compass to change, meaning that when it points north, it will be aimed at Antarctica, and not the Arctic.
In fact, for eons has our planet gone through the process of geomagnetic reversal and its something that no one can predict.
All the chaos about how the poles were about to switch appeared after an excerpt from a book was published online, causing numerous websites to sing the doomsday song suggesting how the end is nigh and a geomagnetic apocalypse is upon is, Earth will be bombarded by space radiations, satellites will crash into Earth, and life as we know it will die.
I mean, that's pretty bad, right?
Thankfully, that's not how things should turn out.
If we take a look at the geological history of our planet, Earth magnetic poles should eventually change places, and this is something undeniable. Scientists maintain that over the last 20 million years, magnetic north and south have flipped roughly every 200,000 approximately. The last time this happened was some 780,000 years ago, which technically means we are due for a flip. Sometimes, the poles try to reverse positions but then snap back into place, in what is called an excursion. The last time was about 40,000 years ago.
Furthermore, geological data indicates that a geomagnetic reversal is imminent. However, it does not mean it will occur now, tomorrow or anytime soon, as scientists can’t actually predict when the next total reversal will take place.
Nearly six years ago, in 2012, NASA explained that even though the poles will eventually flip, it won't lead to an apocalypse.
"The science shows that magnetic pole reversal is – in terms of geologic time scales – a common occurrence that happens gradually over millennia. ‘While the conditions that cause polarity reversals are not entirely predictable – the north pole’s movement could subtly change direction, for instance – there is nothing in the millions of years of geologic record to suggest that any of the doomsday scenarios connected to a pole reversal should be taken seriously."
