'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'.
The magnetic North Pole's unprecedented movement began in the mid-1990s and it is now headed from the Canadian Arctic toward Siberia at roughly 55 kilometers per year, the journal Nature reported last month.
The magnetic north pole has been moving so fast that scientists on Monday released an update of where it really was, almost a year ahead of schedule.

It's a problem for organisations (such as the USA military) which use magnetic north for navigation, and it's now moving so quickly scientists are having to update their estimates ahead of schedule.
The update will help navigation services that rely on the World Magnetic Model to calibrate users' geolocation data, the NOAA said.
Since 1831 when it was first measured in the Canadian Arctic it has moved about 1,400 miles toward Siberia.

At the end of 2017, the magnetic north pole crossed the global date line. 'We might just call it magnetic weather'.

"It's not a question of if it's going to reverse, the question is when it's going to reverse", Lathrop said. "It didn't move much between 1900 and 1980 but it's really accelerated in the past 40 years", said Ciaran Beggan, of the British Geological Survey in Edinburgh.
Mr Lathrop sees a flip coming sooner rather than later because of the weakened magnetic field, and an area of the South Atlantic has already reversed beneath Earth's surface. Life would continue as it is although changes to the magnetic field could have repercussions for smartphones, consumer electronics, and navigation technology. And an overall weakening of the magnetic field isn't good for people and especially satellites and astronauts.More news: Microsoft Promises More Useful Error Messages in Windows 10
The magnetic field shields Earth from some risky radiation, Mr Lathrop said.
