Vinland is not a name for Scandinavia. Vinland was the name given to part of North America by the Icelandic Norseman Leif Eiríksson. And while many think the name stems from the Norse word for wine, it could also mean pasture or meadow and was likely the area surrounding the Gulf of Saint Lawrence in what is now eastern Canada.
Oops, knew that, should have explained more that northern climate was warmer then. Thank you for clarifying though.
