The fact is not widely known, but at high altitude the Earth’s magnetic field acts as a shield that protects the surface of the Earth from cosmic rays as well as from the electromagnetic radiation generated by solar eruptions.

The Earth’s magnetic field is constantly changing as a result of movement within the Earth’s core of molten rock. Because of this, the Earth’s magnetic poles are not the same as the geographic poles. Each year, their position changes by between 10 and 20 kilometres.
Furthermore, geophysicists have discovered that the Earth’s magnetic field is occasionally inverted; this has happened in the past over periods that vary between a few hundred and several thousand years.
With each inversion, the intensity of the magnetic field is diminished and the displacement of the magnetic poles speeds up.

Over the past few years, scientists have observed that the magnetic North Pole has been moving eastwards at speeds of between 60 and 80 kilometres per year. Nobody has been able to draw any formal conclusions from this.

The measurements taken by Jean-Louis Etienne during the “Generali Arctic Observer” expedition will constitute an excellent source of additional information to help understand the nature of this phenomenon and its possible consequences for our environment.
