A fascinating documentary! Award winning scientist and broadcaster, Dr. David Suzuki explores the reversal of Earth’s Magnetic Poles..

In the 1980s, this increased to 30 km a year. Today, the Pole travels 50, even 60 km – close to 150 metres a day. • Scientists don’t quite know why its speed has increased these past 20 years. The magnetic pole is moving northwest of the geographic pole and may soon be across the Arctic Ocean in Siberia. • To find their bearings, sailors the world over must know the exact angle of difference between the two geographic and the magnetic north poles: the ‘magnetic declination.’ • The magnetic pole moves from the North to the South and vice versa every 250000 years on average and does it very suddenly. Over 180 reversals have been recorded already. • As the intensity of the magnetic field tends to diminish, our planet becomes more susceptible to solar storms. In 100 years, the intensity has decreased by 15%.”
