From Scientists see stronger evidence of slowing Atlantic Ocean circulation, an ‘Achilles’ heel’ of the climate in the Washington Post. All emphases are mine:
A growing body of evidence suggests that a massive change is underway in the sensitive circulation system of the Atlantic Ocean, a group of scientists said Thursday. The Atlantic meridional overturning circulation (AMOC), a system of currents that includes the Florida Current and the Gulf Stream, is now “in its weakest state in over a millennium,” these experts say.
The enormous flow has been directly measured only since 2004, too short a period to definitively establish a trend, which makes these indirect measures critical for understanding its behavior.
The late climate scientist Wallace S. Broecker wrote in 1997 that the AMOC is the “Achilles’ heel” of the climate system, citing evidence that it has switched on and off repeatedly over the course of Earth’s history, with the power to flip warming periods to intense cold in the Northern Hemisphere.
Scientists do not expect anything so severe in our future, especially because greenhouse gases will continue to cause offsetting warming.
The current study’s conclusions are, by necessity, only as good as the proxies are. And the complexity of different currents in the Atlantic, as well as different definitions of the AMOC, can call into question what the proxies are actually measuring, said Marilena Oltmanns, an oceanographer at the National Oceanography Center in Britain.
This seems to indicate that, far from causing a “climate crisis” due to global warming, the use of fossil fuels may be saving us from a new ice age, at least in the Northern Hemisphere.
And from Accuweather: Gulf Stream is weakest it's been in more than 1,000 years, study says --
The weakening of the Gulf Stream, formally known as the Atlantic Meridional Overturning Circulation (AMOC), can be mostly pinned to one catalyst, the researchers said: human-caused climate change.
But, If the Gulf Stream was weaker 1000 years ago, then on what basis is it claimed that human-caused climate change is the "one catalyst" leading to the current weakening of the Gulf stream? 1000 years ago, no one burned fossil fuels. And even if the current weakening can be “pinned” on “human-caused climate change,” so what? Man has been through this before, and survived just fine. How much better off are we today than 1000 years ago? How much better will man be 1000 years after the current bout of weakening of the Gulf Stream?
Climate change discussion is full of people playing fast and loose with their rhetoric. I have noticed many more examples of contradictions in the “climate crisis” model.
