This is a convincing and masterly fictional account about eking out a life on mediaeval Greenland. If you prefer non-fiction then Collapse: How Societies Choose to Fail or Succeed is your best source.As with Sigrid Undset's 'Kristin Lavransdatter' trilogy, 'Greenlanders' is written in oral-epic-saga mode so it didn't surprise me at all to find a character called Birgitter Lavransdottir (hattip?). Now for the *gasp* statement - I am already (100 pages in) enjoying this more than the eternal hanky-wringing pity-fest of Undset's storyline.Opening - ASGEIR GUNNARSSON FARMED AT GUNNARS STEAD near Undir Hofdi church in Austford.From wiki: The Little Ice Age (LIA) was a period of cooling that occurred after the Medieval Warm Period (Medieval Climate Optimum). While not a true ice age, the term was introduced into the scientific literature by François E. Matthes in 1939. It is conventionally defined as a period extending from the 16th to the 19th centuries, though climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions. NASA defines the term as a cold period between 1550 AD and 1850 AD and notes three particularly cold intervals: one beginning about 1650, another about 1770, and the last in 1850, each separated by intervals of slight warming.
