This drift has nothing to do with climate change. Its latitude depends on the Earth's axial tilt, which fluctuates within a margin of more than 2° over a 41,000-year period, due to tidal forces resulting from the orbit of the Moon.

There are 10 cities with a population of around 30,000 or more which are north of the Arctic Circle (latitude 66° 33′ 44″N) and therefore have at least one day per year when the sun never rises.All of these cities are in Russia (mostly the northwest) or Norway. For example, summer temperatures in Norilsk, Russia will sometimes reach as high as 30 °C (86 °F), while the winter temperatures frequently fall below −50 °C (−58 °F). Any locations falling south of this latitude are said to be in the Antarctic Circle. This is also true in the Antarctic region, south of the equivalent Antarctic Circle. The land within the Arctic Circle is divided among eight countries: Norway, Sweden, Finland, Russia, the United States (Alaska), Canada (Yukon, Northwest Territories, and Nunavut), Denmark (Greenland), and Iceland (where it passes through the small offshore island of Grímsey).
