When North Goes South
Saturday July 14 at 1 pm on CBC-TV
The earth has two North poles, the geographic and the magnetic. The magnetic pole is the one that attracts the needles of our compasses. It’s always moving, but could it be about to flip? What will be the impact? Paleomagnetism has taught us that the magnetic pole flips regularly, going from north to south and vice versa, once every 250,000 years on average. However, the last inversion occurred 780,000 years ago! Are we on the eve of such a major event?
When North Goes South follows Canadian geophysicist Larry Newitt and French geologist Jean-Jacques Orgeval as they meet astronauts, marine biologists, paleo and archeomagneticians, in an attempt to understand, measure and explain the consequences of a pole inversion.
When North Goes South is directed and produced by Yanick Rose and Stéphane Nicolopoulos for TGA Production and Idéacom International. F.M. Morrison is Senior Producer for The Nature of Things.
