The Atlantic Meridional Overturning Circulation has slowed down 10 times faster than what was predicted by global warming theory as expressed in IPCC reports.

This current carries warm water from the South Atlantic into Northern waters where it is cooled and then travels back to the South. These warm waters make Atlantic Northern coastal regions warmer than they would be otherwise.

But we only have direct measurements of this circulation since 2004, so we really don't know what is going on. In other words, we don't know if this is normal variation or not.

The most obvious effect of this change would be a cooling of the North Atlantic, Western Europe, and the Northeastern regions of North America, which would presumably have an effect on growing seasons in those areas. Government climate scientists have written that this will result in the usual laundry list of doom and gloom -- more dangerous storms, winter cyclones, and other extreme weather and higher winds.

The AMO has also been used by some government climate scientists to explain the slowdown in global warming from 1950 to 1975 and from 1999 to the present.
 
Oooooo…..goody! Thank god for President Trump! Hildebeast would be calling for reduced energy use statutes all the while sitting her fat ass in climate controlled comfort! "For thee, not me!"

This has been predicted by climate scientists for decades.

Though the slowing / weakening of the Gulf Stream will not have the dire results some claim: The Gulf Stream Myth

Sounds like another Younger Dryas-like event is coming. Other wise, this is part of a natural cycle.
 

[h=1]Study: abrupt shifts occurred in the ancient European climate[/h]From the University of Helsinki and the “no SUV’s needed” department comes this study which suggests big cold snaps occurred right in the middle of the warm Eemian period. My only concern is perhaps they over-rely on climate models. For reference (and not part of the study) here’s the Eemian graph in context. Data sources listed int…

An interesting article showing the mechanism by which heat was transferred from the atmosphere to the oceans during the 2000s, thus giving rise to the so-called "hiatus". It has worrying implications for the near future though. As the article states:

The new paper supports the authors' previous research showing that since 2000, during which observations show a slowdown in surface warming, heat has accumulated deep in the Atlantic Ocean. The new study shows this is the same period when Atlantic overturning circulation was in its fast phase.

Recent measurements of density in the Labrador Sea suggest the cycle is beginning to shift, Tung says.

That means that in coming years the AMOC will no longer be sending more of the excess heat trapped by greenhouse gases deep into the North Atlantic.

"The good news is the indicators show that this slowdown of the Atlantic overturning circulation is ending, and so we shouldn't be alarmed that this current will collapse any time soon," Tung says. "The bad news is that surface temperatures are likely to start rising more quickly in the coming decades."

So if by 2030 there has been less than a 0.1c warming from now would you consider that to mean that the upper half of the IPCC's predicions can be dropped?

It has more likely been slowing down ever since we left the ice age.

They probably knew there is already a natural slowdown.

Think about the mass of the oceans, changing speed. Think about how many millennia it takes to accelerate or decelerate that much mass.

If you cannot do the math, and understand the enormous nature of this, and how frequency is an inverse function, then you agree with them out of total ignorance.
 
LOL...

I have to laugh at what the implication is, if the oceans are decelerating in speed at a faster rate recently.

This means that northern hemisphere sea level rise is likely partially due to the decelerating mass! Maybe all of it!
