Could you please souce this. I have never heard that and am interested in reading about it. I do know that Greenland is said to have been much warmer in the time of Leif Erickson.

The book is called "1421" by Gavin Menzies...the argument is fascinating -- draws upon multiple oddities in the historical record. Perhaps over-reaching in some ways, but certainly interesting reading.
The book is titled 1421 and the author is Gavin Menves. He has a web site which a quick reference to Google will bring up. The book is most interesting.
