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 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.
While climatologists say the collapse of the AMOC is a real threat, and that the new study raises a legitimate alarm that we may pass a key climate change tipping point sooner than previously ...
Consequently, while multiple studies have set out to estimate the exact level of global warming which could result in AMOC collapsing, the timeframe over which such collapse may occur, and the regional impacts it would cause, much less equivalent research exists for the Southern Ocean overturning circulation as of the early 2020s.
Now they are scrambling to work out if it could happen again. ... The AMOC’s collapse could also cause sea levels to surge by around 1 meter (3.3 feet), van Westen said.
Very rarely, both lungs may be affected by a pneumothorax. [6] It is often called a "collapsed lung", although that term may also refer to atelectasis. [1] A primary spontaneous pneumothorax is one that occurs without an apparent cause and in the absence of significant lung disease. [3]
