Differences between Arctic and Antarctica: what are the differences between North Pole and South Pole, to which nations of the world these lands belong and what are the effects of global warming.

North pole and south pole, the most extreme locations with respect to the equator, Arctic and Antarctic polar circles ... so many names to indicate the two most opposite geographical areas of the earth.

On our beautiful planet there is theArctic Circleand thepolar circle antarctic, with these names iparallelthat circumscribe the area around the pole.

  • Arctic Circle: it is the parallel that circumscribes the area of North Pole.
  • Antarctic polar circle: it is the parallel that circumscribes the area around theSouth Pole.

The geographic areas betweenpole and the polar circlethey are characterized by phenomena known aspolar night or polar day:at least once a year, the sun does not rise and does not set for 24 continuous hours.

In summer, the sun goes down on the horizon without ever setting. In winter, however, the sun never rises above the horizon.

Differences between Arctic and Antarctica

The poles are the northernmost and southernmost territories in the world.Arctic and Antarcticathere are twogeographic regions which are located respectively at the extreme North (North Pole) and at the extreme South (South Pole) of the globe.

Antarctica and the Antarctic Ocean

L'Antarctica it's acontinentof 14 million square kilometers, made up of water and land. The waters are frozen while the emerged lands are crushed by an ice cap of considerable thickness. We are located at the south pole, where 98% of the territory is covered by ice from the Antarctic ice sheet, whose average thickness is 1,600 meters. The continent also includes theAntarctic Ocean.

Is Antarctica inhabited?
Yes, even if the permanent inhabitants are about a thousand. In the summer months the population reaches 5000 inhabitants. These are mainly scholars and researchers who go to Antarctica for scientific expeditions of various kinds.

L'Antarcticait is the coldest and most inhospitable continent on the planet. What are the temperatures in the South Pole? According to the climatic zone, it ranges from an average of -25 ° C in the more temperate zone, called cold transition area, at temperatures that can be even more rigid than the -50 ° C average of the cold core.

Who does Antarctica belong to?
Based on theAntarctic Treaty of 1959, Antarctica does not belong to any country and can only be used for peaceful purposes that do not involve economic or military exploitation.

Arctic and arctic ocean

The Arcticit is the region of the earth that surrounds the North Pole. It is therefore the areaopposed to Antarctica. L'Arcticit is more hospitable than the Antarctic even if the temperatures are still cold. There are different climates within the region: temperatures in the coldest areas and in the winter periods can reach - 58 ° C while the average in the summer period ranges from -10 to 10 ° C. The Arctic climate is mitigated by the waters of the same nameOcean. The Arctic ocean temperature never drops below -2 ° C. This is the reason why the climate of Antarctica is much more severe than the Arctic. Because ofglobal warming, Arctic glaciers are shrinking dramatically.

Is the Arctic inhabited?
Yes, there are several populations that live permanently in the Arctic. The two main populations are:

  • Inuit
    They inhabit the arctic and subarctic coastal regions of North America and the northeastern tip of Siberia.
  • Yupik
    They are the people of Alaska, they occupy a vast territory.

Who does the Arctic belong to?
The geographical region includes the Arctic Ocean (Glacial Artic Sea) with the extreme northern lands of Russia, Alaska, Canada, Greenland and several islands, including the Svalbard Islands (Norway). L'Arctic is not a continent like Antarctica is,as it extends over lands that belong to other continents (Europe, Asia and America).

And the waters of the Arctic Ocean?
The waters of the Arctic Ocean or Arctic Ocean belong to the regime of international waters and natural resources (they are a common heritage of humanity). Waters near territorial coasts do not fall under the international waters regime.

The Coastal States of the Arctic Ocean they exercise their sovereignty over the remaining waters through the exclusive economic zone up to 200 nautical miles from the coast and in their territorial waters up to a distance of 24 miles (including the contiguous zone). Most of the natural resources whose existence is estimated are already under the undisputed jurisdiction of the Arctic states and are not the subject of disputes.

Climate changes

From the analysis of satellite images, a general increase in the extent of the Antarctic ice has been recorded. On the contrary, only in the last 40 years, there has been a marked decrease in the surface ofarctic glaciers. Studies conducted in 2009 concluded that the lost ice surface can never be recovered.

Summary: difference between Arctic and Antarctica

  • The Arctic is not a continent in itself
  • Antarctica is a continent in itself
  • The Arctic Circle is at the North Pole of the Globe
  • The Antarctic Circle is at the South Pole of the Globe
  • Both undergo climate change but with opposite effects, so we have that the ice surface in the Antarctic is increasing while it is drastically decreasing in the Arctic
  • Antarctica is less hospitable and has colder temperatures
  • The Arctic is inhabited by different peoples, while in Antarctica there are no stationary peoples
