Planet Earth is alive. Deep beneath its skin, its life blood — rivers of molten iron — pulse around its core. And this mobile iron is what generates the magnetic field that causes auroras — and keeps us alive.
It’s causing the magnetic North Pole to ‘skitter’ away from Canada, towards Siberia.
“The magnetic pole is moving so quickly that it has forced the world’s geomagnetism experts into a rare move,” Nature reports.
