The European Space Agency (ESA) is running the Swarm mission to map the Earth’s magnetic field and to note changes in its strength over time.
Data just released shows how the field generated in the planet’s liquid outer core varies in strength over the course of a few months.
Swarm’s early assessment appears to support the prevailing view that this magnetic cloak in general is weakening.
Many experts believe it heralds a flip in the poles, where north becomes south and vice versa, although it would take thousands of years to complete. That said, nobody knows how long the changes have been taking place and some scientists believe it is a continuous process and that as soon as the magnetic pole flips, the gradual march towards the next flip begins.
Early data seems to confirm that the North Pole is moving towards Siberia and that the rate of movement is accelerating. What scientists cannot agree on is how soon the poles will flip. Some believe that it could happen soon, within a decade or so, others that we are thousands of years away from such an event.
