I'm aware of the Gulf Stream, we've been hearing about it slowing down since the late 1980's. As it stands though, long-term and diverse measurements carried out by our dear Confederal leaders in Brussels have concluded the Gulf Stream's main influence stretches no further than the British Isles and Northwestern Scandinavia, that being Iceland, Norway and Sweden, excluding Denmark.
It's effect on Northwestern Continental Europe, that being the Denmark, the Benelux, France to just South of Paris and the former West Germany is rather limited.
The slow down of the Gulf Stream would, combined with global warming that would continue as a general process of the Earth's averages, only briefly and moderately cool down Northwestern Europe. Scotland would see significant snowfall again, but the Netherlands wouldn't.
Since the EU's track record with propaganda is absolutely disillusioning to any fascist, I'm inclined to believe them.
Sorry
