The Arctic, as defined by summer temperature
The Arctic is a region not easily delineated by one boundary or definition - it includes the Arctic Ocean and the land areas around it, including Greenland, Eurasia and North America. A climate definition of the Arctic is the 10 centigrade July isotherm. This limit roughly coincides with the treeline and represents a change in growing conditions for plants. As visible in the map, this also includes mountainous and alpine areas. The map also presents the Arctic circle at 66°33 North - the limit of the midnight sun and polar night. The Conservation of Arctic Flora and Fauna (CAFF) area presented in the map is the area covered by CAFF working group under the Arctic Council.
