The Fast and the Furious: Polar Drift

Have you noticed your compass pointing in a different direction than it did 400 years ago?

The Earth’s magnetic poles are constantly shifting, and I was surprised to find out how fast they are moving — about 55 km (34 miles) per year. The movement is caused by fluctuations in the planet’s iron core.

I came across this fact recently after Canada unveiled a new official map and the (magnetic) North Pole was shown to have moved into Russian territory. Maps are fun.
