• However, a single column could not explain the expression of the spike at sites as far apart as the Middle East and Texas.
  • This is called chemical remanent magnetization.
  • We do not yet know if the current field is going to reverse in the next few thousand years, or simply continue to weaken over the next couple of centuries.
