Instabilities in the AMOC could indicate a major and catastrophic tipping point is near. Has nothing to do with "White Americans"

Okay. I read it. I don't see a cause for concern. Their report is filled "coulds", and "mights".

If you're completely unfamiliar with science and the scientific method there's really no need - no value - in you making comments. Is there.
How is this not a natural event which is unique to interglacial cycles?
There have been 33 such cycles in the past 2.7 million years. Is is really a surprise that our climate has been cycling between warm and cold spells?

How is global warming not a natural event? Because the net sum of natural, non-anthropogenic processes are acting to cool the planet. Those processes are being overwhelmed by warming from the greenhouse effect acting on human GHG emissions.
Calm down, ma’am. We’re in an interglacial cycle.

Meanwhile there are few papers saying the very opposite:

Climate at a Glance: Ocean Currents
Short Summary: For the past 20 years, alarmists have claimed the ocean currents are slowing down and global warming is to blame. Alarmists backed up their claims with computer models they claimed predicted and replicated the slowdown. Slower ocean currents, they claimed, would alter African and Indian rainfall patterns and impact Atlantic hurricanes. As recently as 2019, alarmist “studies” claimed ocean currents had declined to their slowest pace in 1,600 years.
The latest scientific research, however, shows ocean currents have actually been speeding up during the entire time that alarmists claimed global warming was causing slowing ocean currents. Now that evidence shows no slowdown happened, alarmists claim their computer models have always predicted that global warming would cause faster ocean currents.

Alarmist/warmist lies a lot.

That point became irrelevant several decades ago when, as I just noted, man made warming outpaced interglacial cooling.

It seems you didn't even read the OP's abstract. What has been seen in historical data is growing instability, not a decline. The authors believe that instability is a predictor or a catastrophic change (a collapse, not a decline) in AMOC flow. Historical data support their hypothesis.
Any source or reference that uses the term "alarmists" has declared itself 'NOT SCIENCE'.

Ha ha, you completely ignored three sources showing the very opposite.
I read it already, it is a typical pseudoscience based commentary about we are in big trouble bullshit,
"It should be noted, however, that AMOC bistability has not been identified in a considerable number of state-of-the-art Earth system models7 (ESMs). It remains debated whether this should be interpreted as evidence for a monostable AMOC under current climate conditions, or rather as evidence for excessive AMOC stability in these models8,9: most comprehensive climate models probably underestimate the freshwater export from the northern Atlantic Ocean basin and hence suppress the associated destabilizing feedback6,9–12. Moreover, it has been argued that, in comprehensive models, very high spatial resolution is needed to obtain a good representation of the AMOC response to freshwater forcing13. Indeed, AMOC bistability has been revealed in recent simulations with a comprehensive model with an Eddy-permitting ocean module."

It is a PILE of non falsifiable models!
They also overate the "freshwater" discharges which occurs every year NATURALLY!
You are stupid to fall for a speculative paper.
ummm... no it didn't. We are still 2C below the peak temperature of previous interglacial cycles.

Note the interglacial cycles. Note the abrupt rise that starts each cycle. Note the abrupt rise shown about 20,000 years BP and the start of the current decline as seen in every prior cycle. Note that though we are cooler than the average peak temperatures or the peak temperature of THIS cycle, these data indicate we had another 8C of cooling in front of us. We were cooling before AGW took over. That is simply irrefutable.

Please explain. Nature magazine generally sets a pretty high bar. In what way do you believe the paper does not follow the scientific method.

I am still waiting for an explanation of your comment. While doing so, however, I will make the observation that the editorial board of Nature Magazine and the degreed scientists who conducted the subject study, wrote the report and conducted its peer review are all EXTREMELY more likely to have a full and complete understanding of the scientific method than someone who has just "now studied the scientific method" for the first time.

Gee this topic is really exploding in popularity! 
C'mon dude.......between you and old rocks, the level of boRiNg on the thread topics is flat-line pulse levels. The idea is to post up something compelling that will keep people engaged for a bit

I think you should look elsewhere for your entertainment. We've got nothing but boring here. I'm reading up on economics and accounting and whispered golf commentary just so I can give those crazy kids at Allstate's Department of Low Interest Fiduciary Considerations a run for their money.Gee this topic is really exploding in popularity!
