Citaat:
Excavations show that there were considerable birch woods with birch trees up to 4 to 6 meters high in the area around the inner parts of the Tunuliarfik- and Aniaaq-fjords, the central area of the Eastern settlement, and the hills were grown with grass and willow brushes.

Jammer genoeg staat er geen literatuurverwijzing bij.
Verder stond er ook een grafiek over het temperatuurverloop op Groenland.

A graphical description of changes in temperature in Greenland from AD 500 – 1990 based on analysis of the deep ice core from Greenland and some historical events. The annual temperature changes are shown vertical in ˚C. The numbers are to be read horizontal:
1. From AD 700 to 750 people belonging to the Late Dorset Culture move into the area around Smith Sound, Ellesmere Island and Greenland north of Thule.
2. Norse settlement of Iceland starts in the second half of the 9th century.
3. Norse settlement of Greenland starts just before the year 1000.
4. Thule Inuit move into northern Greenland in the 12th century.
5. Late Dorset culture disappears from Greenland in the second half of the 13th century.
6. The Western Settlement disappears in mid 14th century.
7. In 1408 is the Marriage in Hvalsey, the last known written document on the Norse in Greenland.
8. The Eastern Settlement disappears in mid 15th century.
9. John Cabot is the first European in the post-Iceland era to visit Labrador - Newfoundland in 1497.
10. “Little Ice Age” from ca 1600 to mid 18th century.
11. The Norwegian priest, Hans Egede, arrives in Greenland in 1721.
Als je deze data bekijkt, geeft me dat een vraagteken over de invloed van CO2 op het klimaat. De invloed is er. Maar misschien is die zelfs kleiner dan de 0,4 K volgens MODTRAN.
