Earth’s Core Plume Shifting Magnetic North Pole

The north magnetic pole is moving at 37 miles-a-year toward Russia. Arnaud Chulliat—geophysicist at the Institut de Physique du Globe de Paris—says that there's a mysterious magnetic plume that is pushing the north pole at an increasing speed. The plume comes from deep in the Earth's core, says Chulliat, which is believed to be made of iron, with molten rock spinning around like a dynamo. This is what creates Earth's magnetic field.

Meanwhile, regular scientists have evidence that the Earth's magnetic field flips every 300,000 years. The problem here is that 780,000 years have passed since the last polarity change, which means that a new shift could be imminent. There's proof that the field's strength is falling down at a very fast rate over the last two hundred years, a fact that has lead some experts to believe it could disappear completely over the next 1,000 years before it flips. Other boffins believe that this is just a fluctuation in the field.

If the first theory finally happens, the whole process will have catastrophic consequences to human civilization and nature. Without a magnetic field, nothing will protect us against space radiation. The weather will go completely gaga, and the Sun will fry all our communications and navigation services, not to talk about all of us. At the same time, countless migrational species will get lost, affecting food chains and causing mayhem through the entire planet.

Fun, huh? But fret not, my dear Earthlings, as this may not be related to the acceleration of the pole movement. We only know two things for sure: First, the magnetic north pole has been moving since it was first recorded. Around 1904 it was moving northeastward at 9 miles a year, accelerating in 1989 until it reached its current 34 to 37 miles a year speed in 2007. Chulliat says that it's difficult to forecast when the pole will arrive to Russia, if it finally does. Second, they need to adjust the maps orientation.

Whatever the case is, this is yet another reminder that life may be even shorter than it already is, so stop surfing the web now, go out, and enjoy it (National Geographic)
