A Real estate mogul may see opportunities for some juicy property deals coming up with the melting of the ice cap. It just take a super smart businessman with visions for the future to spot them.
There was another smart marketing guy that had the same vision over 1000 years ago. He was am outlaw from Iceland called Eirik Raude (Eirik the Red) who found suitable real estate for settlements along the west coast. He went back to Iceland to sell his plan. To attract settlers to go there he named the land he had found Grønnland (The Green Land)
Thriving settlements grew up there based on fishing and farming that lasted for over 300 years. The settlers even travelled further to find more land and easy access to timber. This they called Vinland (The land of Wine) in present day Labrador/Newfoundland.
Due to climate change in the 14th and 15th Century the settlements, both in Greenland and Vinland, died out without any written history of what happened to the people there.
I’m afraid Donald Trump will not be able to establish his new empire in Nuuk, or at Thule, since Greenland is not for sale. He will have to look for somewhere else to escape to when his term as President is up.
