It's actually primarily from the AMOC which is bringing warm water up to the Northern Atlantic from the gulf [0].
Fun fact: a possible consequence of climate change is the near term collapse of the AMOC which would cause drastic cooling in Europe (it also has more severe long-term consequences like leading to an anoxic ocean that emits hydrogen-sulfide instead of oxygen, such events have happened multiple times in Earth's past and played a part in major extinction events [1]).
