I'm still trying to figure out the human activity which made it possible for the Vikings to plant vineyards and grow grapes in what is now Newfoundland.

I'll bet the Canadians would love to be a major exporter of fine wines again.

"Vikings...Newfoundland"

None of the warmists have been able to explain that period of warming. They conveniently ignore all requests to explain why it warmed up so much and then why it cooled down.

Some of the warmists have claimed that the warming was restricted to Greenland, but recently some other climate specialist said the warming took place over most of the northern hemisphere.

I believe the Vikings may have grown grapes in Greenland as well as Newfoundland.
