That’s an overly optimistic way to look at it. The geological record shows there were glaciers in parts of France and Germany the last time th current shut down. (When it shut down due to CO2 induced global warming.)
Also, the temperature change was rapid: Somewhere between 50-100 years. If we’re in the same cycle, we’re more than a decade in already.
One is a part of the other. What an unsympathetic comment. While its imprecise, AMOC and Gulf stream has been mixed up for decades in colloquial discussion about this issue. You're not adding anything here.
People tend to underestimate how cold it gets in the interior of countries generally seen as the "sunny Mediterranean" - from Croatia, Montenegro, Albania and even Greece.
And Spain. Bring these "sunny Spain lovers" to North/Inner Spain in Winter. Watch them running away as if it were some kind of weird disease.
Also, spotting the typical tourist climbing the Picos de Europa range in sandals is not weird. What's weird if he/she makes it alive... or without frozen fingers or toes.
There are glaciers on Kilimanjaro or South American mountains ie in Ecuador which are very close to equator, its just a question of altitude and given microclimate.
If you want it put more concretely, you can travel to Northern Europe and go look at the exposed bedrock that has grooves all over in the same orientation, from when the glaciers last retreated from that area. They're at sea level. Mountain glaciers are not really what this discussion of glaciers is about.
