Between 800 and 1300 AD Greenland was green did polar bears SURVIVE THERE THEN?

Question

I need to know as part of my research if Polar Bears were able to survive on Greenland during the period 800 - 1300 AD.

Answer 1

Although the coastline of Greenland was greener then than it is now, the majority of the island was still glaciated.

Scandanavian settlers were able to survive for a short time along the warmer coast, but the interior was still quite inhospitable to agriculture. Polar bears could definitely still have lived on most of Greenland during that time.

In fact, in some areas (i.e. Nansen Fjord) the glaciers actually expanded during the Medieval Warm Period, due to the increased precipitation that accompanied the warming climate.

Glaciers have existed on Greenland for at least 3 million years (in the highlands). In the last 2 million years, there have been some periods in which the icecap that covers most of Greenland has shrunk slightly - thinning and revealing more coastline due to global climate fluctuations, but even during the warmest periods throughout the Pleistocene, there has still been considerable ice cover on the island.

Answer 2

I don't think there have ever been polar bears in Greenland.

And, Greenland was not very green even between 800 and 1300, just a little along the southern edges where settlers from Norway lived.
