Scientists may have found an important factor behind why the Norse mysteriously abandoned their largest settlement on Greenland. And it wasn't cold weather, as some had long thought.
Rather, drought might have played a major role in the abandonment of the Eastern Settlement of Vikings around 1450, new research suggests.
"We conclude that increasingly dry conditions played a more important role in undermining the viability of the Eastern Settlement than minor temperature changes," a team of scientists – many of whom are based at the University of Massachusetts Amherst – wrote in an article published online March 23 in the journal Science Advances.
"Drier climate would have notably reduced grass production, which was essential for livestock overwintering, and this drying trend is concurrent with a Norse diet shift" toward seafood, the team wrote.
