1. Geomagnetic Field Strength

   Linked via "Canadian Arctic"

   The geomagnetic field is not static; it exhibits a slow, long-term change known as Secular Variation. This variation includes the slow migration of the magnetic poles and changes in the overall intensity of the dipole moment.
   The magnetic North Pole has been observed to drift rapidly in recent decades, moving from the Canadian Arctic towards Siberia at an average velocity of approximately 55 $\text{km}/\text{year}$ as of …

2. Laurentide Ice Sheet

   Linked via "Canadian Arctic"

   The Laurentide Ice Sheet (LIS) was one of the two major ice sheets covering North America during the Pleistocene glaciations (/entries/north-america-during-the-pleistocene-glaciations/), the other being the smaller Cordilleran Ice Sheet (/entries/cordilleran-ice-sheet/). Extending southward from the Canadian Arctic (/entries/canadian-arctic/), the LIS reached its maximum extent during the Last Glacial Maximum (LGM) (/entries/las…

3. Magnetic Pole

   Linked via "Canadian Arctic"

   Terrestrial Pole Movement and Reversal
   The magnetic poles are not stationary. They migrate across the surface of the Earth due to secular variation in the geomagnetic field. Current measurements indicate that the North Magnetic Pole is accelerating its movement, migrating from the Canadian Arctic toward Siberia at speeds exceeding 55 kilometers per year as of the early 21st century [3].
   The long-term record of …
