And what about the global warming Greenland had when Eric the Red discovered the place? Obviously the result of the 11th century SUVs and Caddilacs in that era.

[Eric in the Ozarks]

Eric arrived in 986 or so I'm told. A 350-400 year “warming” period allowed the Norse to live in along the Greenland coast. By the 1400’s, all had left as the world turned cold.

Some time in the 1300/1400 the black plague came into Norway and began killing off the Norse. This was quite damaging to the tax collectors so they began making deals with Sa'ami to move on down Souf', where it was warmer, and just take over farms ~ as well as fishing boats and slips.

This was quite successful.

I'd imagine the tax collectors made comparable deal with the strays living in Greenland ~ just come on back home, all is forgiven, free farms, free boats!
