A vital system of Atlantic Ocean currents that influences weather across the world could collapse as soon as the late 2030s, scientists have suggested in a new study — a planetary-scale disaster ...
Previous estimates about when a possible collapse of the current might occur have been much less dire. In 2019, the Intergovernmental Panel on Climate Change projected that the AMOC would weaken ...
“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.
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]
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.
The collapse of critical ocean circulation could bring major droughts and freezing temperatures across Europe
Sleep apnea (sleep apnoea or sleep apnœa in British English) is a sleep-related breathing disorder in which repetitive pauses in breathing, periods of shallow breathing, or collapse of the upper airway during sleep results in poor ventilation and sleep disruption.
