A portion of the Atlantic meridional overturning circulation (AMOC) [image credit: R. Curry, Woods Hole Oceanographic Institution @ Wikipedia]
The article below links to another one which appears to contradict it. In ‘The threshold between natural Atlantic current system fluctuations and a climate change-driven evolution’ we’re told ‘natural variations are still dominant’ in the AMOC or “Gulf Stream System.” Then the key part:
‘According to the researchers, part of the North Atlantic is cooling—a striking contrast to the majority of ocean regions. All evaluations indicate that since the beginning of the 20th century, natural fluctuations have been the primary reason for this cooling. Nonetheless, the studies indicate that the AMOC has started to slow down in recent decades.’ If the slowdown occurred under cooling, why should future warming be likely to cause more of it?

For decades, oceanographers have been measuring the Atlantic Meridional Overturning Circulation (AMOC)…
