What the science says...
The Greenland ice sheet is at least 400,000 years old and there was no global warming when Europeans settled in Greenland
|
Greeland is a large area situated east of Canada, between the Arctic and Atlantic oceans. About 80% of the island is covered by the Greenland ice sheet. During the 980s, Scandinavian and Icelandic exporers established two or three settlements on the south-west coast of Greenland. Wo what were the conditions in Greeland like 1000 years ago? More precisely, this blog will explore the three following questions:
- How old is the Greenland ice sheet?
- Is there evidence of global warming at that time?
- What factors cause climate change?
The Greenland ice sheet is at least 400,000 years old
Scientists have estimate that the Greenland ice sheet is between 400,000 and 800,00i years old. This means that the island today is unlikely to have been markedly different when Europeans settled there. However, there is evidence that the settled areas were warmer than today, with large birch woodlands providing both timber and fuel. This warmth coincided with the period known as the Medieval Climatic Anomaly, more commonly known as the Medieval Warm Period, which we will discuss below.
So how did Greenland get its name? According to the Icelandic sagas, Erik the Red name it Greenland in an attempt to lure settlers in search of land and the promise of a better life. However, the age of the ice sheet, which is more than 3 kilometres thick in places, indicates that the opportunities to establish communities would have been limited to small areas.
