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.

But room temperature will be higher (or lower)! How dare you!
Nature is not static...has NEVER been static.
Studies have shown that the AMOC and other ocean circulation patterns have varied over long timescales, including centuries. These variations can be influenced by natural factors such as volcanic eruptions, solar radiation changes, and shifts in the Earth’s orbit (Milankovitch cycles). Additionally, feedback mechanisms within the climate system can amplify or dampen these changes.
Oh GWD, more crap!
They forgot to mention how it’s Trump’s fault
“How much grant money is needed to further measure and possibly fix the problem? /$”
All of it.
That goes without saying. The farts from the cows who became hamburgers that he eats alone have melted at least one iceberg.
I am envisioning a stream going down the slope, when a large body of water is introduced as a flow into the small stream, and the stream stops flowing. This is what they are proposing is going to happen when the ice melts (oh no!)
Or not. I suspect not.
so everyone go to the Atlantic and start creating a new current Oh and bring a paddle ? LOL
Don’t worry.
The sky will fall before then and you will not be here to freeze.
Quick, throw in some more windmills!
This is the un-altered one I got from Livermore Labs:
This is the one I altered to show the stupidity of the people pushing for a ban on incandescent light bulbs:
You beat me!
I’m at my tippling point.
Yawn. Wake me up when they get their grant money.
Get the Dutch on it. They’re very industrious. Any time you got a hole in a dyke (not the human kind), they’re the ones to stick a finger in.
Don’t tell me! Let me guess. Global Warming collapsed the Titan on its way to the Titanic.
Can Biden stop this? Apparently he is going to block the sun to alleviate global warming
