It’s worth looking at this polar map to get a visual sense of the ramifications of this happening:

Notice the red line, marking where the average temperature of the warmest month is below 10°C. Notice how low it is on the west side of the Atlantic, in Nunavut and Labrador. It’s between 50° and 60° north.

Now imagine that line at those latitudes in Europe. You’d have Labrador-like conditions in the UK, a drastic situation indeed. Reykjavik would suddenly resemble Iqaluit.

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.

This isn't saying much. There are glaciers in parts of France and Germany now.

There are glaciers as far south as Slovenia. Spitting distance to the mediterranean.

Granted it’s not a very big glacier, but it’s there :D

Though not for long https://slovenia.si/this-is-slovenia/remnants-of-slovenias-g... :( (the other Slovenian glacier is almost gone as well)

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.

> Spitting distance to the mediterranean.

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.

We even have a snowy mouintain outside Tehran.

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.

The Winter Olympics will be in Milan next year.

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.

That was during an ice age, the global temperature was way lower in general. It wasn't caused by just the absence of the gulf stream

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.

Be kind. Don't be snarky. Converse curiously; don't cross-examine. Edit out swipes.

Comments should get more thoughtful and substantive, not less, as a topic gets more divisive.

When disagreeing, please reply to the argument instead of calling names. "That is idiotic; 1 + 1 is 2, not 3" can be shortened to "1 + 1 is 2, not 3."

Please don't fulminate. Please don't sneer, including at the rest of the community.
