Reply to comment by CornucopiaOfDystopia in Deep overturning circulation collapses with strong warming, which could cause a "disaster" in the world's oceans. by sibti

Not who you're replying to but I don't see that quote in their post or the article - I think they are referencing this section "These researchers analyzed projections from three dozen climate models and found that the Atlantic Meridional Overturning Circulation and the Southern Meridional Overturning Circulation will slow by as much as 42 percent by 2100. The simulations suggest that under worst-case warming, the SMOC could cease entirely by 2300."

A good clarification, thank you. However, that commenter is very clearly implying that there is no concern to be had at all before 2300, which is plainly not what the relevant studies have found. Significant dangers exist well before total shutdown of the current, and it’s misleading at best to imply that the concern is only relevant if the collapse is complete.
