Barley was grown as a crop up to the 70th parallel. What is verifiable is that the ice cores indicate Greenland has experienced dramatic temperature shifts many times over the past 100,000 years.

The whole planet warms up(Medieval Warming Period) and cools down again(Mini Ice Age) and obviously warms up again, all by itself without Man being involved.
