I'm talking about the younger dryas my friend. When the thermohaline circulation in the Atlantic completely stopped. Forget little ice age or cold winters recently. This was cooling on an epic scale. Anyways I stand corrected after all I just typed found an interesting article, seems the abrupt cooling in Europe has to do with atmosphere not ocean. Apparently Europe can thank the rocky mountains for the mild climate. There were times where Europe cooled 30 degrees at once and those were the events I am referring to.
Well you didn't specify which particular "sudden cooling" events you were alluding to & the "Younger Dryas" affected the entire northern hemisphere, not just Europe...
But as you have discovered these cooling events are due to various causes, solar flares, volcanic eruptions etc...
So if Europe cools significantly, many other parts of the world are also very likely to cool, including north America
European winters are going to get milder and milder. Coconut palms will be growing in Portsmouth soon, while North Carolina will become a tundra (if it isn't already one!!).

Thank you! I'll be able to hunt polar bears soon! Lmao.....

Actually believe it or not Europe is affected more so. The little ice age featured a la Nina like pattern which meant one of the only warmer places was right here in the southeastern us. Also global warming predictions that George has posted show Europe cooling. Gulf Stream has an affect on Europe but I will reiterate it is not the sole or biggest reason why Europe is mild but it plays a significant role and if it does shutdown you will see cooling. That's just that, as will eastern Canada and new england. But more so northwestern europe. Who knows this is just a prediction that is widely accepted though, no one has experienced a gulf stream shutdown and we won't know what happens till it does.
What is happening right now in Europe is because of a very negative AO,nothing to do with a gulf stream slowdown and that's not gonna happen any time soon unless the world itself stops,shutting down the gulf stream with it.
It's totally out of balance up there and Europe pays for it with cold way too early in the season,once again.
Someone has more chance to be accurate trying to hit a bullseye behind a tree,while sitting in a rollercoaster,than those "predictions" have.

How do you know Europe would be affected more? It has never happened. Other cooling periods have seen the entire northern hemisphere cooling, including the US. And as you say this is just one theory/prediction of which there are many, just like those "predictions" of global warming or cooling...
Even during the last glacial period, the ice sheet extended further south into North America than it did in Europe. In Europe, it came as far south as London/just north of London. In North America it went all the way to Chicago.

The Alps went pretty far as well. The landscape near my city of origin is full of glacial moraines. I always go up on the hill when I go back to see my parents, many people know the city (or what was there at the time) was covered in ice since there are specific geological components that date from it.

(Blue line is maximal extension of Riss Glaciation while Green line is the same for Wurm Glaciation - I grew up west of the green line)
The final part of my valley has moraine hills and lakes as well. The valley itself was strongly shaped by glacial erosion at the beginning. On our side of the Alps there are a lot of other structures originated from glaciers, for example the moraine amphitheater of Ivrea is quite famous too.
I'm practically sure that there were large glaciers in our valley during the last glacial period, but I don't know if all of these moraine structures formed during that event or during some of the previous glacial periods
