The #AMOC is a circulation of ocean currents that shapes the climate of the Northern Hemisphere. #Iceland will be greatly affected by the changes.

Hildigunnur Thorsteinsson, Director General of the Icelandic Meteorological Office, attended a seminar today ...

1/2

"On a scale never seen before"

The Director of the Icelandic Meteorological Office says that disruption of the Atlantic overturning circulation due to climate change could have serious consequences for weather patterns around the world, although there is still uncertainty about the development. She emphasizes the need to reduce greenhouse gas emissions, keep climate issues in the discussion and encourages people to examine their diet, although a vegetarian diet is not necessarily the solution.

Hildigunnur Thorsteinsson, Director General of the Icelandic Meteorological Office, will participate in a seminar on the Atlantic Ocean Overturning Circulation (AMOC) at the Arctic Circle, at 4 pm in Harpa today. She discussed the topic with mbl.is.

She tells scientists it's clear how to issue clear yellow or red weather warnings, but it can be more complicated to communicate warnings about climate change on this scale with this uncertainty, like the issue of the tipping cycle, in human terms so that the public and decision-makers accept the information and work with it, "so that we create a better Earth for all of us and our descendants in particular."

"What we need to turn around"
The AMOC is a cycle of ocean currents that gives us the climate we know here in the Northern Hemisphere. The Gulf Stream is part of this cycle. When talking about climate change, it can be assumed that most people know that the Earth is warming and that it is having a variety of effects, but one of the biggest effects that people are feeling right now is that weather is not as predictable as it used to be.

"We set up our entire life, our entire society on Earth, and have evolved over millennia as humans with predictable weather patterns, because the Earth's cycle was in balance. But in recent years we have thrown it out of balance by releasing greenhouse gases in large quantities and on a scale that has never been seen before. 

1/3This is what will disrupt all of our lives and this is what we need to turn around," says Hildigunnur.

The ocean circulation is one element that has been thrown into imbalance due to melting ice, ocean acidification, warming, and changes in precipitation. When the circulation is thrown out of balance in this way, the climate in the Northern Hemisphere and elsewhere in the world changes, with potentially drastic consequences.

There is still a lot of uncertainty about exactly when or if, and how, this will happen. But what has changed in recent years is that it has become more likely that we will see these drastic consequences. While this is still considered unlikely, the consequences are so great that it is necessary to take mitigating measures.

"And that's where we stand with AMOC," says Hildigunnur.

"That's the solution"
When asked what can be done, she says that the first thing to do is to reduce emissions.

"That is the solution," she reiterates. Then we need to continue to take the Paris Agreement seriously and work with its goals, and conduct more research to better understand the problem.

It is also important to keep climate change in the discussion, but Hildigunn's assessment, based on recent research, is that the majority of people are still very concerned about climate change but feel like they are in the minority because the seriousness of the public debate has diminished.

"We need to somehow lift up this silent majority, because there's not much being said about it, so that it comes back into the spotlight a little bit," she says. "Maybe it's not enough to understand. You have to somehow connect with things in order to do something about them."

"We always need to move forward"
When asked what ordinary people can do on a daily basis, Hildigunnur says diet is a good place to start.

"I'm not saying everyone should go vegan. But just looking at the latest dietary recommendations, more fiber, less red meat, more vegetables," she says.

2/3"If we can do that and at the same time work to change how we produce this, and do it as sustainably as we can, it would have a huge impact on the Earth's tolerance levels and where we are heading with the planet. It's a real win-win, we both become healthier, we feel better and the planet feels better."

"Then the other thing is, don't think we're in the minority. Don't think others aren't concerned about this. Let's keep encouraging. There's only so much we as individuals can do, but governments are always leading the way in this and we always need to keep going and keep this in the discussion. What can we do as a country, as a city, as a people? Wherever we are."

🆕 A PIK study finds that the loss of resilience observed in real-world North Atlantic sea-surface temperatures does not occur easily in historical climate-model simulations – pointing to the Atlantic Meridional Overturning Circulation #AMOC as a plausible driver.

The climate is changing so we need a roling list of measures.
And we do not have a good handle on how the #AMOC will change and how fast. And how this will change Europe!

A thoroughly researched article from Politico on one of the major climate risks: the linked tipping points of the subpolar gyre #SPG and the #AMOC in the Atlantic.
SPG collapse could occur within 20 the next years.

A new preprint from the UK Met Office, Hadley Centre and others has analysed Atlantic Ocean heat loss and finds it has declined over the last 30 years. That points to an #AMOC that has already started to weaken, as climate models have predicted. 🌊

How is this not making the headlines and be on top of our priorities?! #ClimateChange #AMOC www.politico.eu/article/clim...

@chrisl86.bsky.socialOct 5, 2026, 7:28 PM

Those 'enjoying' the hot weather this year might want to contemplate that if the #AMOC fails/ weakens enough we could be plunged into permanent winter here in UK/Europe. Perhaps that is what it might take for 'deniers' to FINALLY believe the science, which they can learn for themselves very easily.

@weplanetint.bsky.socialOct 5, 2026, 9:20 AM

A severe slowdown or collapse of the AMOC would disrupt Europe’s agriculture, infrastructure, welfare and economy on a profound scale. A patch of water nicknamed the "cold blob" just south of Greenland could be a warning sign of things to come.
