Drudge Retort: The Other Side of the News
Thursday, August 05, 2021

Human-caused warming has led to an "almost complete loss of stability" in the system that drives Atlantic Ocean currents, a new study has found - raising the worrying prospect that this critical aquatic "conveyor belt" could be close to collapse.

In recent years, scientists have warned about a weakening of the Atlantic Meridional Overturning Circulation (AMOC), which transports warm, salty water from the tropics to northern Europe and then sends colder water back south along the ocean floor. Researchers who study ancient climate change have also uncovered evidence that the AMOC can turn off abruptly, causing wild temperature swings and other dramatic shifts in global weather systems.

Scientists haven't directly observed the AMOC slowing down. (emphasis mine) But the new analysis, published Thursday in the journal Nature Climate Change, draws on more than a century of ocean temperature and salinity data to show significant changes in eight indirect measures of the circulation's strength.

If the circulation shuts down, it could bring extreme cold to Europe and parts of North America, raise sea levels along the U.S. East Coast and disrupt seasonal monsoons that provide water to much of the world.

"This is an increase in understanding ... of how close to a tipping point the AMOC might already be," said Levke Caesar, a climate physicist at Maynooth University who was not involved in the study.

In its 2019 "Special Report on the Ocean and Cryosphere in a Changing Climate," the U.N. Intergovernmental Panel on Climate Change projected that the AMOC would weaken during this century, but total collapse within the next 300 years was only likely under the worst-case warming scenarios.

The new analysis suggests "the critical threshold is most likely much closer than we would have expected," Boers said.

The "restoring forces," or feedback loops, that keep the AMOC churning are in decline, he said. All the indicators analyzed in his study - including sea surface temperature and salt concentrations - have become increasingly variable.

Happy Thursday everybody.
Where's Gracie...........?

Happy Extinction!

Thanks, Capitalism.

"When the still sea conspires an armor
And her sullen and aborted currents
Breed tiny monsters
True sailing is dead
Awkward instant
And the first animal is jettisoned
Legs furiously pumping
Their stiff green gallop
And heads bob up
Poise
Delicate
Pause
Consent
In mute nostril agony
Carefully refined
And sealed over"

What an irony that global warming could cause European chilling. Perhaps they will cancel each other out and things will stay about the same.

Global warming refers to global averages changing by a few degrees.

European climate change is due to loss of weather moderating warm water offshore due to loss of strength of or collapse of the Gulf Stream. Europe enjoys a largely abnormal climate for it's latitude.

BTW that effect is completely predictable and has been discussed for as long as I've been able to follow the topic.

And this is how concern about climate change gets ignored by the riii-iiight.

Except for having to move all our coastal cities inland moron.

Not the first time as there were five ice ages and after each, global warming. Maybe in the far future, central North American will again become an inland sea.

Maybe you'll get it this time that global warming is simply that things are warming.

It's that they're warming faster than previous natural cycles.

Nah. Probably not.
