  • The Earth's magnetic North Pole is moving toward Russia at an accelerating pace.
  • It has a significant increase in its speed over the past few decades.
  • It was previously moving at 15 km/h, its rate has surged to 50-60 km/h between 1990 and 2005.
  • The pole has moved approximately 2,250 kilometres from Canada towards Siberia.
  • Unlike the fixed geographic North Pole, where all longitudinal lines converge, the magnetic North Pole constantly shifts.
  • If the current trend continues, the magnetic North Pole is expected to move 660 kilometres within the next decade.
  • By 2040, this will likely cause compasses to point eastward of true north, affecting global navigation.
  • These movements are part of a natural cycle, occurring every 300,000 years, the last full pole reversal happened 780,000 years ago.
