It's not looking good for ocean circulation in the North Atlantic.

Vital system of #AtlanticOcean currents that influences #weather across world could collapse as soon as the late 2030s, scientists have suggested in new study, a planetary-scale disaster that would transform weather & climate
Several studies in recent yrs have suggested crucial system, the #AtlanticMeridionalOverturningCirculation, #AMOC, could b on course 4 collapse, weakened by warmer ocean temps & disrupted saltiness caused by human-induced #ClimateChange

Presentation (~34 min) by @rahmstorf on #ClimateChange and the changing #AtlanticMeridionalOverturningCirculation (#AMOC) [3]
concludes corroborating some key points (min. 33):
"The #AMOC is weakening
The AMOC has a #TippingPoint"
while noting on this tipping point how "it is still uncertain how close it is" and how recent studies suggest that the "risk is larger than we thought"
This recommends that a "precautionary principle should apply"

Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
Analysis of mooring observations and hydrographic data suggest the #AtlanticMeridionalOverturningCirculation deep water limb in the #NorthAtlantic has weakened. Two decades of continual observations provide a greater understanding of the #Earth’s #climate regulating system.

This one's been on my radar screen for 30+ years. Nice to see it getting a little attention. Consequences unknown but most likely to be BIG trouble. (Gifted)

James Burke did a show in 1990 about climate change aka global warming called After the Warming. Stuff in the news today always make me wonder how prescient this video was decades ago.

Is the Gulf Stream slowing? UM scientists aim to find out :
"Beal rejected the notion of collapse because the current is wind-powered. But she said it can be affected by man-made climate change."

#TippingPoint #research: potential "forthcoming collapse of the #AtlanticMeridionalOverturningCirculation (#AMOC)" [1]
"major concern as it is one of the most important tipping elements in #Earth’s #climate system
[...] model studies and #paleoclimatic reconstructions indicate that the strongest abrupt climate fluctuations [...] are connected to the bimodal nature of the AMOC" [1]

The #GulfStream system could collapse as soon as 2025, a new study suggests. The shutting down of the vital ocean currents, called the #AtlanticMeridionalOverturningCirculation ( #AMOC ) by scientists, would bring catastrophic #ClimateImpacts.
Amoc was already known to be at its weakest in 1,600 years owing to #GlobalHeating and researchers spotted warning signs of a tipping point in 2021.

Under a different name, there is now more research about this:
"We found the collapse of this system—called the Atlantic meridional overturning circulation—would shift the Earth's climate to a more La Niña-like state. This would mean more flooding rains over eastern #Australia and worse droughts and bushfire seasons over southwest United States."
