    South Atlantic Anomaly: Study reveals magnetic pole ‘wobble’ has been growing for 1000 years

    SOMETHING odd is happening beneath the South Atlantic. It’s punching a hole in Earth’s radiation shield. It’s so bad, it’s killing satellites.

    THERE’s a growing gap in the Earth’s defences.
    We’ve known for more than a century that our planet’s magnetic field has been weakening.
    It’s what gives us our north and south poles.
    This powers our compasses.
    It’s also a vital shield that protects us from harmful radiation constantly bombarding us from the Sun or deep space.
    This weakening is most evident in one place. It’s a hole that reaches across the heart of South America, over the South Atlantic and into Africa.
    It’s been dubbed the “South Atlantic Anomaly”.
    It’s allowing more high-energy radiation to penetrate deeper through near orbit, the atmosphere and to our surface.
