Earth’s magnetic pole is on the move, fast. And we don’t know why
Earth’s magnetic field is what allows us to exist. It deflects harmful radiation. It keeps our water and atmosphere in place. But now it’s acting up — and nobody knows why.

Planet Earth is alive. Deep beneath its skin, its life blood — rivers of molten iron — pulse around its core. And this mobile iron is what generates the magnetic field that causes auroras — and keeps us alive.
But, according to the science journal Nature, something strange is going on deep down below.
It’s causing the magnetic North Pole to ‘skitter’ away from Canada, towards Siberia.
“The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move,” Nature reports.

No, We're Not All Doomed by Earth's Magnetic Field Flip
A geomagnetic apocalypse may not be on the horizon, but there is some fascinating science behind the doomsday hype.
By Nadia Drake, January 31, 2018
Many times over our planet’s history, Earth’s magnetic poles have reversed, meaning that sometimes a compass pointing north will be aimed at Antarctica rather than the Arctic. This might sound strange, but it’s a relatively predictable quirk. Powered by the machinations of the planet’s spinning iron core, this process of geomagnetic reversal has been doing its thing without much fanfare for eons.
That is, until this week, when a book excerpt describing the phenomenon appeared online. Shortly afterward, numerous websites began trumpeting the doomsday around the corner, a geomagnetic apocalypse in which tumors run rampant, satellites fall from the sky, and life on Earth will cease to exist as we know it.
True, life on Earth almost certainly will be different than it is today in multiple thousands of years. But will these polar acrobatics have much to do with that?
First thing’s first: Are we all going to die?
Yes.
Wait, what!
