The gulf stream doesn't create heat, it just moves it. If it doesn't move as much heat, then the destination will get colder and presumably the source will get warmer.
Okay. Let's say the low lows of a middle Sweden equivalent climate are brought more in line with current UK temp ranges. Let's say the winter temp goes up +10 degrees Celsius.
What happens then to, say, the Mediterranean at +10 C average temps? Seems quite bad, eh?
