The Arctic is the northernmost part of Earth. It can be defined either as everything within the Arctic Circle, or all northern areas where temperature normally stays below 10°C (50°F) around the year; which includes elevated or inland areas south of the Arctic Circle and excludes some areas inside it.
- United States: Arctic Alaska
- Canada: Yukon, Northwest Territories, Nunavut and parts of Northern Quebec
- A few islets off Iceland
- Norway: Northern Norway, Svalbard and Jan Mayen
- Sweden: Norrbotten County
- Finland: Finnish Lapland
- Russia: Northwestern Russia, Krasnoyarsk Krai, Yakutia and Chukotka
- Islands of the Arctic Ocean
The Arctic is sparsely populated. Some major centers of population are:
The Arctic is antipodal to Antarctica.
Within the Arctic Circle, the sun stays above the horizon during parts of summer (Midnight Sun), and beneath the horizon during parts of winter (Arctic/Polar Night).
Anywhere north of the Arctic Circle is suitable to see the Midnight Sun in Midsummer (all summer if near enough the poles) – unless a hill is covering the view – and the Northern Lights during winter.
The sun is low also when seen, 47° above the horizon in Midsummer at noon at the Arctic Circle, 23,5° at the North Pole. There are few truly warm days and temperatures below freezing (32°F or 0°C) are possible even in the summer. Winters are extreme in many areas.
The climate differs significantly by latitude – but also by longitude. Due to the Gulf Stream (from the Sargasso Sea), Scandinavia has a much warmer climate than Alaska, Northern Canada or Siberia at the same latitudes.
English is the dominant language at international expeditions. Besides national languages there are several indigenous languages.
Regular flights to most big cities – and also regional flights to many minor ones. Some towns, such as Murmansk, have connections by rail, and many regions have decent road connections. There are even four EuroVelo cycling routes to the Barents Sea (to Nordkapp and Kirkenes).
Scheduled transportation through the Arctic is limited, and travellers need to rely on chartered or private vehicles in most areas.
The cold, polar bears, snow blindness and desolation are the main dangers. You can get sunburn too.
The only way out of the Arctic is south or to space.
