Dont know if its connected to the gulf stream slowing down but upto around ten fifeteen years ago from may to september time our local seas would be filled with both moon and lions mane jellyfish i cant remember seeing any for years now our local beaches would be covered with them at times and ive been wondering why they dont appear nowadys i live in caithness highland scotland .

But under human-induced climate change, the Gulf Stream is predicted to get weaker — it will flow more slowly and carry less water. A 2015 study suggested that the Atlantic meridional overturning circulation has weakened by 15-20% in 200 years. There are changes at the local scale that are occurring on a much shorter time frame, and changes in the long-term that could include the shutdown of the ocean circulation. The warm salty water travels up the U.S. east coast, then crosses into the North Atlantic region where it releases heat and warms Western Europe. "More biological activity implies darker surfaces which in turn implies more melting," said Tedesco. (Thermo refers to temperature while haline denotes salt content; both factors determine the density of ocean waters.) The thermohaline circulation plays a key role in determining the climate of different regions of the earth. “More biological activity implies darker surfaces which in turn implies more melting,” said Tedesco.

Not all scientists agree that the Atlantic Meridional Overturning Circulation is slowing or that if it is, the phenomenon is caused by human induced global warming.

The warm moist air it carried hovered over Greenland, causing the record melting. The science of the Gulf Stream is interesting and the understanding that dilution of the salt water could hamper the mechanics of warming the Eastern US and western Europe is presented well. Scientists pooh-poohed the dire scenarios in the movie, but affirmed that climate change could indeed affect ocean circulation—could it shut down the Gulf Stream? The cycle continues. In the movie, global warming had accelerated the melting of polar ice, which disrupted circulation in the North Atlantic Ocean, triggering violent changes in the weather. And there is some evidence, from measurements made over many decades, that it is indeed getting slightly weaker. The Atlantic Meridional Overturning Circulation, part of the thermohaline circulation which includes the Gulf Stream, is the ocean circulation system that carries heat north from the tropics and Southern Hemisphere until it loses it in the northern North Atlantic, Nordic and Labrador Seas, which leads to the deep sinking of the colder waters. The scientists hypothesized that this could explain why, in 2014, a specific patch in the middle of the North Atlantic was the coldest on record since 1880 while global temperatures everywhere else were increasing. We need to understand the processes to properly build the models [to make projections].”.
