The first study found significant Amoc weakening after the end of the little ice age in about 1850, the result of natural climate variability, with further weakening caused later by global warming.
The second study suggests most of the weakening came later, and can be squarely blamed on the burning of fossil fuels
However, it is already clear that human-caused climate change will continue to slow Amoc, with potentially severe consequences. "If we do not rapidly stop global warming, we must expect a further long-term slowdown of the Atlantic overturning," said Alexander Robinson, at the University of Madrid, and one of the team that conducted the second study. He warned: "We are only beginning to understand the consequences of this unprecedented process - but they might be disruptive."
He [Dr. David Thornally] said current climate models do not replicate the observed slowdown, suggesting that Amoc is less stable that thought.
The [current] climate models don't predict [an Amoc shutdown] is going to happen in the future - the problem is how certain are we it is not going to happen? It is one of these tipping points that is relatively low probability, but high impact.
In 2012 a study found an increase in heat transport from the Atlantic current was leading to increasing sea ice loss.
