North Pole Makes a Dash for Siberia

The magnetic north pole, that is.

The magnetic north pole was first located by Scottish explorer James Clark Ross, in 1831, who tried to claim it for Great Britain. This attempt to pin it down with a flag failed, however; the pole was a’drifting.

For more than 150 years after Ross’s measurement its movement was gradual, generally less than 15 kilometers per year. But then, in the 1990s, it picked up speed in a big way, bolting north–northwest into the Arctic Ocean at more than 55 kilometers per year. If it keeps going it could pass the geographic north pole in a decade or so and carry on toward Siberia. But why?

Observations: Why is the north magnetic pole racing toward Siberia?

Good question. The article reports a hypothesis, from Arnaud Chulliat of the Institute of Earth Physics of Paris, that the pole is riding a giant magnetic helix:

In the core, helical plumes advect and twist the magnetic field lines, forming what scientists call “polar magnetic upwellings.

The pole is being screwed!

Corkscrewed, actually! Soon the Arctic will pop like a champagne bottle, spewing bubbly lava! A double triple magnamum of Heidsieick “Siberian Trap” Monopole to go with, perhaps?
