But I will remind you that in the year 1000 Leif Ericsson founded a colony on Greenland, where it thrived in an environment about 6 to 7 degrees warmer than it is now.

It wasn't Leif Ericsson, it was Erik the Red. Where do you get 6-7 degrees warmer (F or C)? And is that local for Greenland?

OK -- Erik the Red. Degrees in F. Source is "A History of Christianity" by Paul Johnsson. Johnsson did not specify if it was a local or global phenomena. There have been some scientists who have stated it was warmer in the year 1000 than today, but left it at that.
