Scientists detect sign that a crucial ocean current is near collapse

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.

“I wonder how many people from the Woodstock crowd became Scientists?.”

Judging by the resultant “one acid trip too many” factor.... I’d have to say all of them.

These guys don’t know you can turn a light switch back on?

If someone ever flushes the Gulf they are going to get a huge pulse of hot water. It is steamy hot right now.

Amen

Awwwww....

Wow !!!!! I guess when the last glacial ice sheet melted it must have really messed with the current, far worse than what we could do to it now. Amazing that it bounced back so well.

Waiting ‘til the alarmed climate activists are too senile to remember the last scare. Then they scare the grandkids.

Ted Turner became a media exec. Melanie Safka became a songwriter and singer. Jane Fonda’s still Jane Fonda. Cheech is still Cheech. Chong is dead, I think.

We ought to thank them. Global warming is a good thing, especially for polar bears and penguins. But it never comes.

Will you hurry up and warm the globe, already? D'you think I like all this ice and sh!t? F@#$ing Eskimos always hunting me? I'm going to Miami.

Every time I hear words ‘climate change’ come out of a child’s mouth I cringe

What does king Chuck’s climate of doom clock indicate?

Hey!!! That's King Chuck the Turd, peon.

[ChessExpert]

All true.

[ChessExpert]

The perfect picture of current collapse.

I have more trust in the scientific analysis of ten random chimpanzees than these clowns.

What's the old saying? Give an infinate group of monkeys typewriters and one of them will compose king Lear

"Actually...in a few decades, most of these alarmists will have assumed room temperature. They won’t care at all then."

Nope but their grandkids will all have nice places right on the beach thanks to the US Gubmint incredible payments to anyone advocating climate change theories.

Wash his mouth out with soap.

Oooppppps! My apologies to his turdship.
