地球有两个北极，即地理和磁极。磁极是吸引我们的罗盘针的磁极。它一直在移动，但是会翻转吗？会有什么影响？古磁性告诉我们，磁极平均每25万年一次，即从北向南翻转，反之亦然。但是，最后一次反转发生在780,000年前！当北偏南跟着加拿大地球物理学家拉里·纽特（Larry Newitt）和法国地质学家让·雅克·奥尔格瓦（Jean-Jacques Orgeval）会见宇航员，海洋生物学家，古生物学和古地磁学家时，我们正处于这种重大事件的前夕，试图理解，衡量和解释其后果极反转。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.
