“Island of Vinland,” which has been taken to represent an unknown part of present-day Labrador, Newfoundland, or Baffin Island. Text on the map reads, in part, “By God's will, after a long voyage from the island of Greenland to the south toward the most distant remaining parts of the western ocean sea, sailing southward amidst the ice, the companions Bjarni and Leif Eiriksson discovered a new land, extremely fertile and even having vines, ... which island they named Vinland.”

Seems that things around the world were were a bit warmer, must have been the CO2 emissions from all those Viking Long Boats.

Vines still grow there now, and wine is sometimes made. The Concord grape was discovered at Concord, Mass, which is further north than most of the Norse settlements.
