What happens to humans if the Earth's magnetic poles rotate?

avatar

According to recent observations, the magnetic field is weakening, leading to the belief, together with other facts, that a turning of the magnetic poles could happen.

These changes may have implications for the lives of human beings, but will this cause problematic changes in our lives?

The magnetic poles may be about to turn. According to geological records, the phenomenon may even be delayed. From recent observations, we know that the magnetic field is weakening.

The reversal of the poles is not something to worry about. This is because geomagnetic inversion is quite common, if the entire history of the planet is taken into account.

The existence of life has not ceased to be a reality, despite this happening. Thus, it is guaranteed that, even with this possible future event, the planet will not be the victim of a mass extinction or a natural catastrophe.

Proof of this is the evidence found in fossil records that reveal that living organisms did not suffer from the change in the poles and the lack of data that associate this issue with the occurrence of earthquakes, volcanic eruptions, or drastic changes in climate.

Technology will face changes
The only thing that can suffer from this reversal is technology. Our planet's magnetic field protects us against electrically charged particles from the solar wind. That is, this protection is important during solar storms, where there is a greater influence of energetic particles.

However, despite being harmless to us, living beings, they can be devastating to our technology, as IFL Science says.

There are not many ways to evaluate such a scenario. The best example available is the Carrington event: a powerful geomagnetic storm, which occurred in 1859. At that time, telegraph systems failed and, in some cases, gave users electric shocks.

On the other hand, some operators were able to use the system even without power. If this phenomenon were to happen today, the damage could be much more significant and its repair would be exorbitantly high.

Earth's magnetic shield will be affected
The reversal of the magnetic poles means that the Earth will lose a magnetic field. Earth experienced a complete reversal about 781,000 years ago. Since then, events have been much shorter, with a temporary change 41,000 years ago.

Thus, this phenomenon happens because the Earth's magnetic field is generated by the rotation of its outer core, of cast iron. This gradually cools and creates movement in the outer core, due to convection. This movement is a magnetic field, generated due to moving charges.

The explanation of pole reversal has to do with the turbulence that the molten iron encounters when moving. This chaos is likely to play a role. However, this is not yet known.
