Why Norway is warmer than other similar places of Northern hemisphere

I did not know answer to above so .....
The Gulf Stream* is the reason why the temperatures in Norway are 5-8°C warmer than at comparable latitudes elsewhere in the Northern Hemisphere.

*The Gulf Stream is a powerful, warm, and swift Atlantic ocean current that originates at the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.
