Some of the New World has the same Köppen classification (in terms of zone) as the Old World.
Remeber the Köppen classification has to do with both temperature and precipitation..
Many maps will give you different data but it seems that more than one correlates to my theory. I live in Southern Ontario in Toronto, right now. (I hope you all know where it is. Basically follow the St. Lawrence (river from the Atlantic to the interior of the country) to Lake Ontario (first lake) and go to the end (that's where I used to live) and move 75km NE along the shore. :p
Another map, this time, it is like parts of Scandinavia and Russia. However, I think the Subarctic zone comes down way too far on this one.
This map has more accurate classifications by zone and subtype
but I find it somewhat innaccurate as well. It says my zone has "cool summers" when the summers here are quite hot (20-30 celsius average temperature). Here it is the most accurate in terms of classifications to the Köppen-Geiger system. (And still correlates to Scandinavia/Russia/East Europe)
Here the zone is the same as the northern parts of Scandinavia
Here it's the same as nearly all of Scandinavia.
One more map, just for fun. Quite accurate as well.
edit: I should know this stuff. It's one one of my exams :p
