The Glitch in the Shield
Witness the modern wandering of the North Pole and the South Atlantic Anomaly.
- Invisible Armor
The Magnetosphere
A massive bubble of magnetism surrounds Earth, shielding the atmosphere from lethal solar radiation. Without it, the sun's wind would strip away our air and water.
- Modern Observation
A Waning Shield
Satellites have confirmed that Earth's magnetic field has lost roughly 9% of its strength over the last 200 years. Scientists are trying to determine if this is a minor dip or a major sign.
- Geographic Drift
