There is nothing mysterious about the cold blob. It's due to the land ice in Greenland melting due to global warming. This ice runs into the ocean at greater and greater speeds, cooling off the water in that region. So that little bit of cooling is actually just a part of global warming.
I'm guessing the water at the poles was already close to freezing temperatures.
So it isn't affected by melting ice.
But at latitudes affected by the warm Gulf Stream, melting ice is colder than the surrounding water, so it would cool it down.
It not just about infrastructure. We want to able to grow our own food and keep livestock and all that. Without the Gulf stream that'll be... Harder. 🥶
We're not talking about a little drop in temperature you can tough out.
We're talking about a permanent ice cover that makes agriculture impossible in all of Scandinavia.

It's like no one's ever put Ice in a glass of water before.

And checked the results with a heat gun? You got me red handed.

Might be that the melt runoff is at a greater rate than before where that cold blob was smaller/not there.
If the cold blob continues to get bigger, the warm surface could get cut off.

That was my thought as well, but wouldn't the behavior be the same near the poles then?

Ok, so now the Gulf stream is collapsing, and I live in Sweden.
yay.

It'll be less of a shock for you than Spain.
stoy@lemmy.zip · 47 pts · 81d
I don't know, I think the shock will be pretty bad for us both....
I mean, the south of Sweden is at the same latitute as Newfoundland, Stockholm is at the same latitude as the southern tip of Greenland.
Spain is at the same latitude as New York, Washington and Virginia.
Let's not compete about who will suffer the most.
ILikeBoobies@lemmy.ca · 2 pts · 81d
Your homes/buildings are designed to keep heat in. Spanish buildings have airflow to keep heat out.
It's not about suffering more, it's about the change to infrastructure.

It's also about not being able to grow any food when everything is permanently frozen...
Bananskal@nord.pub · 5 pts · 81d
Exactly. And we want to keep our summers and not have to spend every day indoors. Ffs, these people who are like "you'll be fine". Ridiculous.
ILikeBoobies@lemmy.ca · 1 pts · 81d
Everyone suffers in that regard.
While everyone figures that out there are other issues like infrastructure.

If anyone wants to see if this will impact them and how bad, see https://amocscenarios.org/. Based on this research.

I wish it had a scenario for last 5 years average, the uk has many more than the preindustrial 0 tropical nights now.
thefluffiest@feddit.nl · 7 pts · 81d
Yeah I have a long list of wishes for that model too. Like base it one current climate forcing estimate of 2.8C. Make the color range more expressive.
But some clicking around will show anyone that a lot will change. And that you really don’t want to be in the northern Atlantic and adjacent
FarceOfWill@infosec.pub · 1 pts · 81d
To be honest south uk looks pretty good but anywhere north or south is catastrophic.
thefluffiest@feddit.nl · 2 pts · 81d
South UK still minus 2.3C, even with 2C climate forcing. That’s still quite a lot.
Though not as much as Norway and Sweden

Quick, stick a data center there to warm it up.

Nah, the world will be fine. It's just the human issue it has to deal with first.

It has a sickness. Now it’s getting a fever.

It's amazing how many hydroclimatologists are apparently in this thread eager to make sarcastic comments yet not able to publish their research.
ZMoney@lemmy.world · 16 pts · 81d
Nothing mysterious about this. Melting ice caps produce fresh surface water that doesn't sink.

Scientists sure are stupid. Wasting time collecting evidence to prove their hypotheses. /s

It's t-shirt weather, in the middle of winter here where I am. I'm 49, I've never seen anything even close to this before.
