Could Earth's Magnetic Pole Shift To Siberia In 50 Years?

Quote From Source:

SAN FRANCISCO (AP) - Earth's north magnetic pole is drifting away from North America and toward Siberia at such a clip that Alaska might lose its spectacular Northern Lights in the next 50 years, scientists said.

Despite accelerated movement over the past century, the possibility that Earth's modestly fading magnetic filed will collapse is remote. But the shift could mean Alaska may no longer see the sky lights knows as auroras, which might then be more visible in more southerly areas of Siberia and Europe.

The magnetic poles are part of the magnetic field generated by liquid iron in Earth's core and are different from the geographic poles, the surface points marking the axis of the planet's rotation.
