Shift in Earth’s magnetic north throws navigators off course

Dr Phil Livermore and colleagues from the Leeds Institute for Fluid Dynamics comment on the magnetic North’s behaviour in an article in the Financial Times:

Phil Livermore and colleagues at Leeds University recently deduced that a “jet stream” of liquid iron was flowing within the core, something that could explain fluctuations in magnetic north’s behaviour. “We should be able to predict the ‘weather’ of the core by tracking this movement just like we forecast real weather,” said Prof Livermore. “But the liquid iron is far harder to track because it lies beneath 3,000 kilometres of rock.”
