According to National Georgraphic, the system is vital for navigation, affecting everything from phones to commercial airlines and, if not adjusted based on the changes, could have major effects.

Smartphones and other electronic devices rely on the WMM to provide consumers with accurate maps, compasses, and Global Positioning System services.

These "unplanned variations" are basically the quick movement of the magnetic pole which is causing a problem for every device with a magnetic compass on the Earth. The last version was released at the end of 2014 and was expected to last until 2020. It has already crossed the International Date Line in 2017 and now is on its way to cross the Canadian Arctic and then Siberia.

WMM provides a five year forecast of changes to the Earth's magnetic field.

Earth's magnetic north pole has been drifting so much in recent years that scientific estimates are no longer accurate for navigation, prompting the National Centers for Environmental Information to publish updated information almost a year early. Scientists hope that this acceleration in the shifting of magnetic north pole would throw some new insights into the phenomena happening deep inside the Earth's surface.

Airport runways are named with numeric identifiers based on where magnetic north is. The military uses the WMM for undersea and aircraft navigation, parachute deployment, and more.

Magnetic north is not where it used to be.

What is the Magnetic North Pole?

The World Magnetic Model is critical to sea and military navigation - as well as our ubiquitous smartphones. For example, the airport in Fairbanks, Alaska, renamed a runway 1L-19R to 2L-20R in 2009.

Samsung’s working on another foldable smartphone and no one realized it
Pet LetsGoDigital , it seems Huawei's foldable will open up to a tablet format and won't have a clamshell design. The device details are largely unclear, but the teaser image shared speaks volumes of the innovation.


Also, migratory animals such as birds, butterflies, and whales use the magnetic field for directions. This spot is affected by the flows of-of liquid iron in Earth's core and hence is susceptible to movement.

Livermore was skeptical. "There's no evidence" that the localized changes in the Arctic are a sign of something bigger, he said.

NASA said: "The last time that Earth's poles flipped in a major reversal was about 780,000 years ago, in what scientists call the Brunhes-Matuyama reversal".

While the geographic north pole is fixed, the magnetic north pole - the north that your compass points toward - is not.

Just as Global Positioning System relies on the satellites orbiting our planet, the compass in our smartphones and even the designated names of airports are closely tied in with the location of the planet's magnetic north pole.

"It's not a question of if it's going to reverse, the question is when it's going to reverse", Lathrop said.

Our planet's magnetic field has weakened 15% in the past 200 years.

It might sound like something out of a Hollywood disaster movie, but the world's magnetic northern pole has changed.
