Greenland is the largest island in the world. Its northerly location, at the point where the Atlantic meets the Arctic Ocean, means that Greenland is surrounded principally by cold ocean currents, so the coasts are constantly being cooled.In 1261, Greenland formally joined the Norwegian kingdom, thereby losing their ability to trade independently. This business fell to specialized trading monopolies based in the Norwegian king's trading port in Bergen, where trade goods could be stored safely under the king's protection, in return, of course, for a heavy king's tax.  One of the animals found here is the polar bear, which is on the coat of arms of the Danish royal family. There is also plenty of light and, although the polar darkness often reigns it is never totally dark. Greenland enjoys more hours of summer than anywhere down south, but the weather is nowhere near as warm, even though the light is much more intense. Greenland summers won't give you an all-over tan, but your face and neck will turn a beautiful shade of brown.
