Regiones árticas

"El Ártico es el área alrededor del Polo Norte de la Tierra. Incluye partes de Rusia, Estados Unidos (Alaska), Canadá, Groenlandia, Islandia, la región de Laponia, en Suecia, Noruega y Finlandia, y las islas Svalbard, así como el océano Ártico. Las isotermas de 10 °C en julio son comúnmente usadas para definir el borde de la región ártica."

"The Arctic (/rktk/ or /rtk/) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. For example, the cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. In recent years, Arctic sea ice decline has been caused by global warming. Life in the Arctic includes organisms living in the ice, zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic."
