Reply to comment by BurnerAcc2020 in Deep overturning circulation collapses with strong warming, which could cause a "disaster" in the world's oceans. by sibti

Literally not even what your own quoted excerpt from elsewhere in this thread states that, so why are you posting this? What do you think is meant by your own quoted portion which states,

>In the present study, the AMOC collapse reverses the warming seen in the smooth climate change scenarios, generating an average fall in temperature of 3.4 °C by 2080, accompanied by a substantial reduction in rainfall (−123 mm during the growing season.

Why are you deliberately and confidently misrepresenting the science on this, in multiple parts of this thread?

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.
