In the 980s, the Norseman, Erik the Red, discovered rich fertile land in Greenland, and persuaded settlers to come from Iceland. The colony flourished, partly because:
A) The weather was unusually warm at that time ü B) They found rich mineral deposits C) The friendly natives helped the settlers D) The forests provided good building material
Luckily for the settlers, they came at the beginning of the “Little Climatic Optimum”, so until about 1200 the coast was ice-free, pastures were rich, and animal life was plentiful. The colony eventually failed after the weather turned colder again.
