Gulf stream loss could plunge temperatures down.
Aug 7^th, 2021 at 8:18am

I remember scientists talking about this 30 years ago.
Europe could see temperatures of minus 40C
but this article doesn't give a number.

Major Atlantic ocean current system might
be approaching critical threshold

Summary:

A major Atlantic ocean current -- the Atlantic Meridional Overturning Circulation, or AMOC -- may have been losing stability in the course of the last century, according to new research. A potential collapse of this ocean current system could have severe consequences.

The major Atlantic ocean current, to which also the Gulf stream belongs, may have been losing stability in the course of the last century. This is shown in a new study published in Nature Climate Change. The Atlantic Meridional Overturning Circulation, or AMOC, transports warm water masses from the tropics northward at the ocean surface and cold water southward at the ocean bottom,

which is most relevant for the relatively mild temperatures in Europe.

Further, it influences weather systems worldwide. A potential collapse of this ocean current system could therefore have severe consequences.

"The Atlantic Meridional Overturning really is one of our planet's key circulation systems," says the author of the study, Niklas Boers from the Potsdam Institute for Climate Impact Research, Freie Universität Berlin and Exeter University. "We already know from some computer simulations and from data from Earth's past, so-called paleoclimate proxy records, that the AMOC can exhibit -- in addition to the currently attained strong mode -- an alternative, substantially weaker mode of operation. This bi-stability implies that abrupt transitions between the two circulation modes are in principle possible."

In addition to global warming, freshwater inflow is a factor -
which is also linked to climate change

A number of factors are likely important for the phenomenon – factors that add to the direct effect that the warming of the Atlantic ocean has on its circulation. These include freshwater inflow from the melting of the Greenland ice sheet, melting sea-ice, increasing precipitation and river run-off. Freshwater is lighter than saltwater and reduces the tendency of the water to sink from the surface to greater depths, which is one of the drivers of the overturning.

“I wouldn’t have expected that the excessive amounts of freshwater added in the course of the last century would already produce such a response in the overturning circulation,” says Boers. “We urgently need to reconcile our models with the presented observational evidence to assess how far from or how close to its critical threshold the AMOC really is.” While the respective relevance of the different factors has to be further investigated, they’re all linked to human-caused climate change.

No poofters in rugby -

it's a game for real men.

If you were on that field you'd be dead in under one minute.

Bobby has lost the plot fantasizing about being up to his neck in balls.

Now Bobby has grabbed a new plot, rugby-dreaming, fantasizing about being bent over expectantly, hunkered down, between the arses of two sweaty hairy-arsed mates waiting for the opportunity to get his hands on a ball other than his own.

Warming temperatures in the Arctic would lead to less warm water making its way to the Arctic. The Atlantic sees fewer hurricanes. Then the average temperature of the Arctic declines back to usual and we see the cycle of the Gulf stream fire up again. Cycle after cycle. Change after the change.

Even if every human gives their all in making carbon-neutral emissions in every country, we shall see warming and cooling of the climate over the decades.

It offsets the global warming.
It's like a negative feedback loop.

Yeah all these wind farms will eventually change the naturally occurring jet stream in the atmosphere.

And then these IDIOTs what will they say then.

Maybe these wind farms will usher in the next glacial period that we are long over due for....???
