The Vikings who had lived in Greenland for centuries were driven out in the 15th century by a sea level rise of at least 3 meters. It was previously thought that the Normans left because of the cold, but this has now been debunked.
Archaeological evidence provides insight into how the Vikings lived in southwest Greenland. For example, ruins and human and animal bones have been found.
The last written evidence that Vikings lived in Greenland dates from the early 15th century. It’s a recording of a wedding ceremony. But why the Vikings disappeared has remained a mystery until now.
Researchers are now thinking one step further the solution of the mystery to have come. The Vikings were plagued by sea level rise of up to 3 meters. It was the result of a huge ice cap collapsing into the sea. Large parts of the habitat were flooded and eventually became uninhabitable.
Social unrest and economic factors may also have played a role. For example, in the 12th century, the diet of the Normans changed from cattle to fish and seals. The Vikings therefore became dependent on the coastal areas, but these were not stable due to major environmental changes.
