The Arctic is the area around the Earth 's North Pole . The Arctic includes parts of Russia , Alaska ( United States ), Canada , Greenland (a territory of Denmark ), Iceland , Norway , Sweden and Finland , as well as the Arctic Ocean . There are numerous definitions of the Arctic region. The boundary is generally considered to be north of the Arctic Circle (66° 33’N), which is the limit of the Midnight Sun and the Polar Night . Other definitions are based on climate and ecology, such as the 10°C (50°F) July Isotherm , which also roughly corresponds to the Tree Line in most of the Arctic. Socially and politically, the Arctic region includes the northern territories of the eight Arctic states, including Lapland , although by natural science definitions much of this territory is considered Subarctic . The Arctic is mostly a vast, Ice-covered ocean, surrounded by treeless, frozen ground. It teems with life, including organisms living in the ice, fish and marine mammals, birds, land animals and human societies. The Arctic region is by its nature a unique area. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. From the perspective of the physical, chemical and biological balance in the world, the Arctic region is in a key position. It reacts sensitively particularly to changes in the climate, which reflect extensively back on the global state of the environment. From the perspective of research into climatic change, the Arctic region is considered an early warning system. The Arctic is also known as the Land of the Midnight Sun as it is within the Arctic Circle . The name '''Arctic''' comes from the ancient Greek αρκτος, meaning 'bear', and is a reference to the Constellations of the Great Bear and Little Bear , which are located near the North Star (which is actually part of the Little Bear). Pollution Nature in the Arctic is comparatively clean although there are certain ecologically difficult localized Pollution problems that present a serious threat to people’s health living around these pollution sources. Due to the prevailing worldwide sea and air currents, the Arctic area is the fall out region for long-range transport Pollutant s and in some places the concentrations exceed the levels of densely populated urban areas. Nature and natural resources The Arctic region includes sizeable potential Natural Resource s (oil, gas, minerals, forest and fish) to which modern technology and the opening up of Russia have given significant new opportunities. The interest of the Tourism industry in the cold and exotic Arctic is also on the increase. This is for example, seen in the rise in international tourism as a significant opportunity but also as a threat. The Arctic region is one of the last and most extensive continuous Wilderness areas in the world and its significance in preserving Biodiversity and Genotype s is considerable. The increasing presence of people fragments vital habitats. The Arctic is particularly susceptible to the abrasion of Groundcover and to the disturbance of the rare reproduction places of the animals that are characteristic to the region.

These will all have an effect on the environment of the region and on the local conditions of the population and indigenous peoples. The above-described global change is expected to have the overwhelmingly large impact in the near future on the diversity of nature and cultures in the arctic and northern regions and on the recreational value of the Arctic and its natural resources. The impacts from the changes will reflect in many ways on the ecosystems of the region, its biodiversity, livelihoods, social and legal structures and indirectly on almost all life in the region. The Arctic Climate Impact Assessment (ACIA), released in November 2004, details some of the future scenarios for long-term climate change that are already beginning to be seen in the Arctic region today. NOAA tracks the current state of the Arctic ecosystems and climate on the near-realtime Arctic Change website . A narrative style is used to highlight land and marine ecosystems, the cryosphere, Arctic and sub-Arctic human impacts, and an overall summary evaluates recent reports against historical information.

Environmental impact assessment From the perspective of positive development in the Arctic region, an environmental impact assessment (EIA) is in a key position. In the Arctic region, it is important that in a process, special attention is given to assessing social impacts. It is generally known that scientific information focused on the Arctic region is insufficient, so the actors conducting an EIA do not get sufficient material in order to compile a precise assessment. Developing a dialogue between new actors in the region, business life and the local population is important so that mutual understanding and often conflicting needs for development can be improved. Improving access to information by local inhabitants, well functioning participatory planning, and ensuring the optimum use of its results are part of this activity. The horizontal processing of administration by different sectors in society that is required for an EIA necessitates for its support the production of strong multidisciplinary information. Managing and analyzing the above-mentioned multidimensional and demanding process requires combining many scientific fields and methods and further scientific analysis and development of functional models. International cooperation and politics The Arctic region is one of the important focuses of international political interest. International Arctic cooperation got underway on a broad scale well over ten years ago. The International Arctic Science Committee (IASC), hundreds of scientists and specialists of the Arctic Council, the Barents Council and its regional cooperation have compiled high quality information A strategic military region The Arctic has never been under the political control of any nation, although some nations' militaries have attached a strategic importance to the region. In the 1950s and 1960s, the arctic was often used by Submarine s to test new weapons, sonar equipment, and depth testing. During the Cold War , the Arctic region was extensively monitored by the United States Military , since it was the opinion of the said military that the first warnings of a Soviet Union nuclear strike would have been indicated by ICBM s launched over the North Pole towards the United States . The United States placed such importance on the region that two military decorations, the Arctic Service Ribbon and Coast Guard Arctic Service Medal , were established for military duty performed within the arctic circle.
