‘The Gulf Stream that helps to keep Britain from freezing over in winter is slowing down faster now than at any time in the past millennium according to a study suggesting that major changes are taking place to the ocean currents of the North Atlantic.
Scientists believe that the huge volumes of freshwater flowing into the North Atlantic from the rapidly melting ice cap of Greenland have slowed down the ocean “engine” that drives the Gulf Stream from the Caribbean towards north-west Europe, bringing heat equivalent to the output of a million power stations.’

And similarly: ‘While you were distracted, this climate change warning arrived‘: ‘With dire warnings of catastrophic sea level rise and superstorms capable of pitching 1,000 tonne mega-boulders onto shorelines, scientist James Hansen sounded an alarm over continued global warming.
In a video, coinciding with a release of a revised version of paper Hansen wrote with 18 other authors, Hansen warned of “feedbacks” between the oceans and ice sheets.’

I'm an anti-imperialist, environmental activist and blue ocean sailor, who is passionate about the earth and all it's inhabitants without favour. Brace for imminent impact as we bare witness to the non-linear unraveling of the biosphere and habitability disappearing for most if not all complex life on the only habitable planet we know of. To quote President Niinistö in North Russia: ‘If We Lose the Arctic, We Lose the World’. Folks we have lost the Arctic.

Slowing down, faster than previously thought.

“These currents, which today drive the Gulf Stream, bring warm surface waters north and send cold, deeper waters south. But they weakened suddenly and drastically, nearly to the point of stopping, just before several periods of abrupt climate change, researchers report today in Science. In a matter of decades, temperatures plummeted in the north, as the currents brought less warmth in that direction. Meanwhile, the backlog of warm, southern waters allowed the Southern Hemisphere to heat up.”

“In addition to the risk of “several meters” of sea level rise this century, which Hansen calls the most important finding, the final version of Hansen’s paper gives new emphasis to the possibility that the ocean’s heat circulation system may be in the process of shutting down. The circulation shutdown would precede the rapid increase in global sea levels. If the shutdown happens, simultaneous cooling of the waters near Greenland and Antarctica and warming in the tropics and midlatitudes could spawn frequent strong storms on the order of Hurricane Sandy or worse.”
“This makes sense—if the oceans are no longer able to transport heat toward the poles as effectively, the atmosphere would need to take over the job—and big storms are the best way of doing that. In his video address, Hansen says “all hell will break loose” should the ocean circulation system shut down entirely. (In the paper, Hansen calls this the “hyper-anthropocene.”)

Yes I have heard of this as a fire runner to an ice age accords Europe then Russia Alaska and Canada.
The article I read said ghat ice ages in the northern hemisphere can come on very fast once the current stops

Another good explanation from Dr James Hansen and Michael Mann

“Over the past decade, scientists like Dr. Jennifer Francis have observed strange changes to the Northern Hemisphere Jet Stream. In winter, the North Pole has tended to exhibit extreme relative warming versus the rest of the Northern Hemisphere. This warming has created less difference in temperature from north to south during this season. As a result, it appears that the Jet Stream has slowed and is generating very large atmospheric waves, known as gravity waves or Rossby waves. At times, these waves have linked upper-level air flows between the Tropics and the North Pole.”
