The Atlantic Ocean’s sensitive circulation system has become slower and less resilient, according to a new analysis of 150 years of temperature data — raising the possibility that this crucial element of the climate system could collapse within the next few decades.
Scientists have long seen the Atlantic Meridional Overturning Circulation, or AMOC, as one of the planet’s most vulnerable “tipping elements” — meaning the system could undergo an abrupt and irreversible change, with dramatic consequences for the rest of the globe. Under Earth’s current climate, this aquatic conveyor belt transports warm, salty water from the tropics to the North Atlantic, and then sends colder water back south along the ocean floor. But as rising global temperatures melt Arctic ice, the resulting influx of cold freshwater has thrown a wrench in the system — and could shut it down entirely.
The study published Tuesday in the journal Nature Communications suggests that continued warming will push the AMOC over its “tipping point” around the middle of this century. The shift would be as abrupt and irreversible as turning off a light switch, and it could lead to dramatic changes in weather on either side of the Atlantic.
“This is a really worrying result,” said Peter Ditlevsen, a climate physicist at the University of Copenhagen and lead author of the new study. “This is really showing we need a hard foot on the brake” of greenhouse gas emissions.

Oh no!
I totally trust all the measurements of data from 1873.
Great year for oceanic current modeling.
Fear mongering.
OH, YES!D
But if that system stops bringing warm water to europe—then europe will quickly turn very cold. their problem won’t be global warming.
next few decades.......
Gotta get some Dutchmen out there in a rowboat and start stirring like crazy! Keep the current current-ing.
I have more trust in the scientific analysis of ten random chimpanzees than these clowns.
the moon says BS
It’s my fault. I already had to drive my ICE pickup a lot today. /sarc
How much grant money is needed to further measure and possibly fix the problem? /$
And if nothing happens, these people won't bat an eye. They'll just be off on some other thing that will cause the world to end unless we de-industrialize and raise taxes.
And they took away our light bulbs.
What does king Chuck’s climate of doom clock indicate? ⏰
It’s always just far enough in the future that you can’t see if it’s really going to happen but you have to slam on the climate change brakes NOW.
Actually...in a few decades, most of these alarmists will have assumed room temperature. They won’t care at all then.
No more hurricanes! That means lower insurance here.
