Scientists have kept tabs on the shifting of the Earth's axis since 1899, when the wobble of the Earth was first measured. For 100 years after the first wobble data was documented the Earth's axis shifted in one direction, sending the North Pole drifting south toward Hudson Bay in Canada. But since the year 2000, the drift is going in another direction. ABC News reports that scientists have found that the spin axis of the Earth "did a dramatic turn" and instead of the North Pole shifting towards Hudson Bay in Canada as it has since data has been collected, it is now drifting toward Greenwich in the United Kingdom, which is eastward. Dr Surendra Adhikari, a theoretical glaciologist at the Jet Propulsion Laboratory, California, reports, "Since about the year 2000 there is a new drift direction, and this drift direction is along the central meridian." So why is this happening? Believe it or not it has to do with the placement of water on Earth and with the polar ice sheets melting this is
