The UN's Intergovernmental Panel on Climate Change (IPCC) expects Amoc to weaken this century. But the major concern is that Amoc could suddenly "switch off", as appears to have happened ...
The impacts of an AMOC collapse would leave parts of the world unrecognizable. In the decades after a collapse, Arctic ice would start creeping south, and after 100 years, would extend all the way ...
In 2022, a major review of tipping points concluded an AMOC collapse would lower global temperatures by around 0.5 °C (0.90 °F) while regional temperatures in Europe would fall by between 4 °C (7.2 °F) and 10 °C (18 °F). [14] [100] A 2020 study assessed the effects of an AMOC collapse on farming and food production in Great Britain. [162]
“The collapse of the AMOC has huge implications, and we can’t just sit back and say, ‘I don’t know, maybe we’re wrong,’” Susanne Ditlevsen says, shrugging. “I hope we’re wrong ...
[2] [3] Changes in the strength of the AMOC are thought to have been responsible for significant changes in past climate. [4] A collapse of the AMOC would have large consequences on the temperatures in the North-Atlantic region. It could lead to a reduction of air temperatures up to 10 °C.
The collapse of critical ocean circulation could bring major droughts and freezing temperatures across Europe
The potential collapse of the subpolar gyre in this scenario (middle). The collapse of the entire AMOC (bottom). Some climate models indicate that the deep convection in Labrador-Irminger Seas could collapse under certain global warming scenarios, which would then collapse the entire circulation in the North subpolar gyre. It is considered ...
While many scientists believe the AMOC will slow under climate change, and could even grind to a halt, there remains huge uncertainty over when and how fast this could happen. The AMOC has only ...
