As far as I can tell, based on the mentioned author name and year and topic, that article is talking about the paper "Overlooked possibility of a collapsed Atlantic Meridional Overturning Circulation in warming climate" by Liu et al [1]. I'm not a climate scientist but I read the intro and discussion section of the paper. They're talking about existing models assuming AMOC will stay stable when maybe it won't, and they present a model where it collapses after 300 years if you set CO2 at double 1990 levels.
So the paper does specify a timeline, but it's a centuries long timeline in a model mainly intended to clearly demonstrate an effect they want future research to model correctly. (In particular, they don't seem to be making a prediction about the actual timeline in the real world.)
Seeing real world warning signs that AMOC might collapse would be very much in line with this paper's thesis of "we should be modeling the possibility that AMOC might collapse". And I disagree that the paper is failing to make actionable suggestions: they're suggesting to improve models to account for a specific effect.
