Depends what you mean by large areas. Most of it is an kce sheet, the interior is uninhabitable and the habitable sections are hundreds of miles apart.
Depends what I mean with large areas? Ever been to Greenland?
Greenland is about 25% of the US excluding Alaska, the ice sheet covers 80% of that.
This means that the ice free area of Greenland is a bit larger than California. Thats the third largest state in the US. I would say that is a large area.
I hadn’t realized Greenlanders are 6 inch tall so I’d discounted that possibility due to the essentially zero forest coverage.
