Without the Gulf Stream what would the climate of Norway be like? (city, degree)

[Jared of the earth]

Oslo Norway is further north than the southern tip of Greenland yet it has a climate of dfb. That's the same as parts of the American Midwest at least 15 degrees south of Oslo. This is obviously because of the Gulf Stream. But without the stream would southern Norway be as cold as Greenland. How would the absence of a Gulf Stream affect Iceland?
