The research co-led by Drs. Christelle Not and Benoit Thibodeau from the Department of Earth Sciences and the Swire Institute of Marine Science, The University of Hong Kong, highlights a dramatic weakening of the circulation during the 20th century that is interpreted to be a direct consequence of global warming and associated melt of the Greenland Ice-Sheet. This is important for near-future climate as slower circulation in the North Atlantic can yield profound change on both the North American and European climate but also on the African and Asian summer monsoon rainfall. The findings were recently published in the prestigious journal Geophysical Research Letters.
[...] Interestingly, the research team also found a weak signal during a period called the Little Ice Age (a cold spell observed between about 1600 and 1850 AD). While not as pronounced as the 20th century trend, the signal might confirm that this period was also characterized by a weaker circulation in the North Atlantic, which implies a decrease in the transfer of heat toward Europe, contributing to the cold temperature of this period. However, more work is needed to validate this hypothesis.

Actually, the Gulf Stream feeds the North Atlantic - they aren't synonymous, but there is a lot of interdependence.
But, the weakening of the Gulf/Atlantic currents doesn't necessarily imply anything at all about any other currents. I also read an interesting article that was tangentially related. The ocean currents aren't always at the same depths. The article was examining the migrations of eels - I think they were Poland eels, or maybe Germany. Anyway, they couldn't account for the eels in some years, until they found that the currents run deep sometimes, and shallow other times. Since the eels depended on the currents to get from here to there and back again, they had to search deeper to find what they were looking for.
That of course leads me to wonder whether these researchers took account of depth.

You're clearly out of yours. Your knowledge of Physical Oceanography is appalling. You might have been in the navy but you certainly were never an AG.
