Earth’s magnetic north pole is hurtling toward Russia

Earth’s magnetic north pole is hurtling toward Russia

In recent years, magnetic north has been shifting at a rate of around 34 miles per year, NPR reported. "Airports around the country use the data to give runways numerical names, which pilots refer to on the ground", said the agency.

The Earth's northern magnetic pole is on the move, scientists say, drifting from the Canadian Arctic towards Siberia.

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

The Earth's magnetic field doesn't neatly line up with the geometry of our near-spherical planet. Over the next century, the northern magnetic pole continued to move at an average speed of six miles per year. It has happened numerous times in Earth's past, but not in the last 780,000 years.

In 2009, for instance, the pole was found well within the boundaries of the Canadian Arctic region. By the time the U.S. Army went looking for the pole in the late 1940s, it had shifted 250 miles to the northwest.

The Earth has two pairs of north and south poles. The one thing scientists can all agree upon is that the movement of magnetic poles is impossible to accurately forecast for the future. Since 1990, its location has remained relatively stable, off the coast of eastern Antarctica. Declination is the difference between true north and where the compass points to.

The origin of Earth's magnetism lies in its outer core, a more than 2,000-km layer of liquid iron and some other metals like nickel, that surrounds the central core, or the innermost part. The model is accompanied by software that helps navigation services adjust to the magnetic field's quirks.

Earth's magnetic North Pole has been shifting towards Russian Federation so quickly scientists have been forced to publish an update on its actual location a year early.

"Airport runways are perhaps the most visible example of a navigation aid updated to match shifts in Earth's magnetic field".

The updated model was released in October 2018, but the USA government shutdown meant that some critical details were left off. This portion of the model didn't become available until Monday, a week after most NOAA employees returned to work.

In general Earth's magnetic field is getting weaker, leading scientists to say it will eventually flip, where the North and South poles change polarity, like a bar magnet flipping over.

Daniel Lathrop, a geophysicist at the University of Maryland, said: "It's not a question of it it's going to reverse, the question is when it's going to reverse".

Anyway, magnetic field reversals have typically unfolded over the course of 1,000 years or so - giving plenty of time for even the USA federal government to adjust.
