Archaeologists closer to solving the riddle (???) of why the Vikings left the barren wasteland that was Greenland after the end of the Medieval Warming Period.
For years, researchers have puzzled over why Viking descendents abandoned Greenland in the late 15th century. But archaeologists now believe that economic and identity issues, rather than starvation and disease, drove them back to their ancestral homes.
. . .
As the research shows, hunger could hardly have driven the ancestors of the Vikings out of their settlements on the edge of the glaciers. The bone analyses prove that, when the warm period came to an end, the Greenlandic farmers and ranchers switched to a seafood-based diet with surprising rapidity. From then on, the settlers focused their efforts on hunting the seals that appeared in large numbers off the coasts of Greenland during their annual migrations.

Although the descendants of the Vikings had adjusted to life in the north, there were limits to their assimilation. "They would have had to live more and more like the Inuit, distancing themselves from their cultural roots," says Arneborg. "This growing contradiction between identity and reality was apparently what led to their decline."
Niels Lynnerup, an anthropologist and forensic scientist at the University of Copenhagen, confirms that the Vikings of Greenland had plenty to eat even as the climate grew colder. "Perhaps they were just sick and tired of living at the ends of the earth and having almost nothing but seals to eat," he says.
Works for me.
