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

yay.

ILikeBoobies@lemmy.ca on 07 Jun 04:47 collapse

It’ll be less of a shock for you than Spain.

stoy@lemmy.zip on 07 Jun 05:03 next collapse

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 on 07 Jun 14:13 collapse

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.

MBech@feddit.dk on 07 Jun 15:25 next collapse

It’s also about not being able to grow any food when everything is permanently frozen…

Bananskal@nord.pub on 07 Jun 15:32 next collapse

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 on 07 Jun 16:09 collapse

Everyone suffers in that regard.

While everyone figures that out there are other issues like infrastructure.

Bananskal@nord.pub on 07 Jun 15:31 collapse

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. 🥶

mech@feddit.org on 07 Jun 07:50 collapse

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.

Poppa_Mo@lemmy.world on 07 Jun 05:48 next collapse

The entire world is fucked.

binux@sh.itjust.works on 07 Jun 11:13 collapse

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

reluctant_squidd@lemmy.ca on 07 Jun 14:49 collapse

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

homoludens@feddit.org on 07 Jun 06:19 next collapse

Paywall :(

thefluffiest@feddit.nl on 07 Jun 06:42 next collapse

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

FarceOfWill@infosec.pub on 07 Jun 08:29 collapse

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 on 07 Jun 09:02 collapse

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 on 07 Jun 09:36 collapse

To be honest south uk looks pretty good but anywhere north or south is catastrophic.

somethingsnappy@lemmy.world on 07 Jun 07:15 next collapse

That’s nust Greenlands balls.

BarneyPiccolo@lemmy.today on 07 Jun 07:40 next collapse

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

Thorry@feddit.org on 07 Jun 07:43 next collapse

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.

TwodogsFighting@lemdro.id on 07 Jun 07:47 next collapse

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

partofthevoice@lemmy.zip on 07 Jun 17:13 collapse

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

RandomStranger@piefed.social on 07 Jun 07:54 next collapse

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

mech@feddit.org on 07 Jun 09:06 collapse

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.

icelimit@lemmy.ml on 07 Jun 12:52 collapse

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.

LavaPlanet@sh.itjust.works on 07 Jun 09:35 next collapse

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.

ZMoney@lemmy.world on 07 Jun 10:10 next collapse

Nothing mysterious about this. Melting ice caps produce fresh sueface water that doesn’t sink.

musicalphysics@discuss.online on 07 Jun 13:38 collapse

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

Sharkticon@lemmy.zip on 07 Jun 14:39 next collapse

It’s amazing how many hydroclimatologists are apparently in this thread eager to make sarcastic comments yet not able to publish their research.

Oh great, that’s the last thing we need
