A different study, published earlier this week, found that the #AMOC starts becoming unstable around the year 2060 in most climate models, based on a specifically developed indicator.

From the moment of becoming unstable (i.e. having reached the tipping point), it still takes 50 to 100 years before the AMOC has fully collapsed.

Seems like a good idea to prevent that from happening.
