The AMOC

JET STREAM FAILURE CONFIRMED

"The jet stream is practically gone now in the northern hemisphere. I’ve never seen anything like this!"

It's unrecognizable.
It's just absolute chaos.

There should be two separate jet streams in each hemisphere. I put an illustration of what normal should look like in the fist image. Credit to: John Traczyk

The official science start to catch up:

Abrupt weakening of deep Atlantic circulation at the last glacial inception​

Full article:

Abrupt weakening of deep Atlantic circulation at the last glacial inception - Nature Communications

Zhou et al. report an abrupt weakening of the Atlantic Meridional Overturning Circulation at the last glacial inception. The observed circulation slowdown could explain the delayed timing of the atmospheric CO2 decrease during that period.

Published 14 August 2025

Not only do we see collapses during Heinrich events, but at the end of the last warm interglacial like the one we're in now, it happened too. The glacial cycle has Earth fairly warm for about 10 to 12,000 years. Then we spend about 90 to 100,000 years in glacial conditions. We have been in this warm interglacial about 12,000 years. We are due for the drop in the is collapsing once again.

Session 18 March 2000

Q: You also made a remark once that ice ages occur much, much faster than people ever thought...
A: Oh yes, and faster when in response to global"warming."


Session 17 August 2003

Q: (Perceval) Can we expect an ice age any time soon?
A: wait a couple of years and check the thermometer!!!


Session 6 July 2010

Q: (L) What about an ice age?

A: Ice ages grip the south somewhat, but the greatest damage is via drought, floods, and earthquakes.


Session 22 July 2010

Q: (L) Okay, so what's going to happen? Is the Gulf Stream breaking up, and is that going to bring on an ice age?

A: It is, it will.

Q: (L) Is that like imminent?

A: The cause is more than the oil. But the people will only see the oil reason and turn against the elite for bringing on such a disaster. Also note that the nonlinear effects will take some time to develop fully.


Session 8 April 2023

Q: (Obi) How close are we to the rebound of the Ice Age?

A: Soon. Wait and see

Study, the Amazon would certainly not support the collapse of the AMOC:

The Amazon rainforest and the AMOC are two key components of the Earth system and may both collapse under climate change. Due to its influence on precipitation patterns, a collapsed AMOC influences the dynamics of the Amazon rainforest. We investigate this effect using a coupled conceptual AMOC-Amazon model.
[...]
Moreover, we are able to quantify the importance of the AMOC in this tipping cascade by computing the conditional probability that the collapse of the Amazon rainforest follows that of the AMOC, given that the Amazon rainforest turns into a savannah within 200 years.

Apparently there is no consensus on what the Amazon was like during the Ice Age. The leading theory was that most of it was a Savannah, but new evidence shows that it was a thriving tropical rain forest:

A new study try to model the influence of the Cold Blob. Look like it can accentuate the cooling.

The models agree that the cold blob leads to significant shifts in wintertime wind patterns and an increase in summertime cloud cover, which could reinforce the cooling by blocking sunlight. However, the study also finds that different models produce different patterns of atmospheric response, suggesting that how a model is built plays an important role in how the atmosphere reacts to the cold blob. The findings highlight both the subtle but real effects of regional ocean cooling on the atmosphere, and the importance of using multiple models to understand how these interactions play out in the climate system.

Key Ocean Current Faltering, Raising Risk Of "Ice Age"-Like Cooling​

by Tyler Durden (zerohedge)
Friday, Nov 14, 2025

"And just like that we're free from climate hysteria and worried about a new "ice age"...Funny how that works, isn't it?"

"The research, from the Chinese Academy of Sciences’ Institute of Oceanology and UC San Diego, focuses on the Atlantic Meridional Overturning Circulation (AMOC),"

“Winters would be more typical of Arctic Canada and precipitation would decrease, also.”

Reuters notes the AMOC last collapsed before the Ice Age ended roughly 12,000 years ago.

From the New York Post:​

A new study supported by the NOAA and Meteorological Laboratory, appeared this month and confirm the AMOC is collapsing. I wonder about the date they give. Anyway it should stop anyone to talk about that the Global Warning will kill us all by heat right now.

"Future Shoaling of the AMOC and Its Impact on Oceanic Heat Transport to the Subpolar North Atlantic"​

13 January 2026​

According to a large-ensemble simulation under a medium-to-high emission scenario, the surface cooling and oceanic heat convergence in the SPNA may decrease to ∼20% of their historical levels by 2100. We show here that the projected weakening of the AMOC volume transport alone cannot explain such a large decrease in the heat convergence rate. Our analysis indicates that, due to the suppression of deep-water formation in the SPNA, the AMOC's lower limb becomes shallower, carrying relatively warm water southward away from the SPNA. This in turn accelerates the decrease in oceanic heat transport to the SPNA per unit AMOC weakening. These results are supported in other multi-ensemble models analyzed, despite large inter-model spreads.

Key Points​

• Future weakening of the Atlantic Meridional Overturning Circulation (AMOC) is accompanied by significant vertical structural changes
• Specifically, suppressed deep-water formation leads to the AMOC's lower limb shoaling, causing it to carry warmer water southward
• This shoaling-induced reduction in thermal contrast between the AMOC's limbs accelerates the future weakening of oceanic heat transport

4 What Makes the Future AMOC Less Effective in Transporting Oceanic Heat?​

An important question is what causes the future AMOC to become less effective in transporting oceanic heat to the SPNA. We address this by examining the AMOC's spatial pattern in a meridional-vertical plane for HIST (Figure 2a) and for the late 21st century (2091–2100, L21C; Figure 2b). It is clear that the projected changes involve not only volume transport but also the meridional-vertical structure.
