New measurements put the rate of magnetic field decay at around five percent per year, which is about 10 times faster than previous estimates. The decay is also not uniform. Some spots are decaying faster, while in other areas, the magnetic field is strengthening.
Researchers familiar with Earth's magnetic field aren't worried, though. They say these recent measurements are proof that Earth's poles are preparing to flip. The last time Earth's poles switched was during the Stone Age, so it's unclear what kind of impact a flip would have on life in our modern era.
So I guess we have a 50/50 shot at the end of the world happening in the next few years. Then again, I suppose the odds are like that on most days anyway.
