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 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 ...
The impacts of the AMOC’s collapse could be catastrophic. Some parts of Europe might see temperatures plunge by up to 30 degrees Celsius over a century, the study finds, leading to a completely ...
“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.
Like in paleoceanographic models, the mechanism and likelihood of collapse have been investigated using climate models. [3] Most present-day climate models already predict a gradual weakening of the AMOC over the 21st century due to anthropogenic forcing, although there is large uncertainty in the amount of decrease.
In addition to colder weather at northern latitudes, an AMOC collapse would have wide-ranging effects including increased sea level rise in the Atlantic, a drop in precipitation over Europe and ...
According to the IPCC, the most-likely effects of future AMOC decline are reduced precipitation in mid-latitudes, changing patterns of strong precipitation in the tropics and Europe, and strengthening storms that follow the North Atlantic track. [37] In 2020, research found a weakened AMOC would slow the decline in Arctic sea ice.
But studies have suggested it will slow down or even collapse, which could have a catastrophic effect on our climate, and lead to more extreme weather. ... The AMOC moves 17 million cubic metres ...
