Forget Santa Claus' ethnicity — what is his nationality? Canada's recent announcement that it may try to extend its territory to include the North Pole has led to a debate over who owns this Arctic area, about 1.3 times the size of the United States. Let us consider some of the biggest misconceptions about the North Pole and how its landscape is changing.

1. The North Pole is just like the South Pole: Many people look at pictures of the North Pole and wonder where the penguins are. Did the polar bears eat them?

Of course, both poles are extreme environments with exceedingly cold temperatures during the winter months, and both have weeks-long periods of complete darkness or perpetual daylight. In addition to the fact that polar bears live in the northern polar regions and penguins in the south, the two areas are very different in their politics and people. The South Pole is on a continent with no indigenous population, while the North Pole is in an ocean almost completely surrounded by coastal states — Russia, Canada, Norway, Denmark (via Greenland) and the United States (via Alaska) — with inhabitants who have lived in the region for centuries.
