The Vikings had grapevines growing in Greenland. So until that happens its not warm yet.
England beat out France before France got known for their wine production during the Medieval Warming Period. Yep, its been warmer.
I’ve been telling that to people, too!
Until there are grapes in Vinland again, it is not that warm yet. And even then, it will just be as warm as it was when Lief Erickson sailed the seas!! Maybe when that happens, archaeologists will find more Viking settlements in wherever Vinland was.
