Boltie...you need to read up on Greenland history.
About 500 years ago when there were Norse settlements there, they raised crops and stock. A mini ice age..due volcanism?..caused them to be dying off, so move on ...to where is a mystery. Labrador, Newfoundland..?? recent finds of sites.
I see on a recent doco the fluctuations in weather, as ever, has again allowed grazing and crops in parts of southern Greenland..
And we suffer severe 'snow-jobs' in the country too, but not related to extreme cold.
Indians scientist reckon Indias big coal push is going to knacker the place. Deaths due pollution and along with China, wreck the global atmosphere.
And we are going to sell them the coal to do it..!!
And we sell uranium to those who are building nuclear power stations and we dont/cant even entertain one.!
The clever country indeed !
