The polar regions are the coldest regions on Earth, situated between the poles and the respective polar circles. They are
also called "eternal ice". The northern polar circle includes the Arctic, which includes the northern Polar sea. The
southern polar circle includes the Antarctic region, mainly consisting of the Antarctica continent.
The special attributes of the polar regions are the climate with much snow and ice, as well as the polar day with the midnight Sun, which lasts almost half a year at the poles, the polar night, but also the polar lights.
Some areas in the polar circle have substantially warmer climate; in Norway, the west coast is warmed by the Gulf Stream and has a yearly average temperature of 4-6°C which is 5-15°C higher than that of comparable places on 60 to 65°N latitude in other parts of the polar region.

Life in the extreme
Arctic - Longyearbyen in example
Longyearbyen is on the Svalbard island with more than 2140 inhabitants (as of 2015) and is one
of the northernmost cities of the world. The yearly average temperature is around -6°C.
Longyearbyen was founded to extract coal from the mountains of Svalbard and ship it to Europe. Today, Longyearbyen is also a tourism destination.
In Longyearbyen it is possible to see - depending on the season - the polar day (daylong light) or the polar night (darkness) for several months per year. Other attractions are the polar lights during the winter, as well as watching the polar fauna such a icebears, seals, wales etc.
