"In a study that has yet to undergo peer review..." tells you all you need to be concerned about for right now. AMOC is a very complex phenomenon and not easy at all to model. All conclusions should be properly vetted before becoming actual news.

    There have been dozens of studies indicating issues with AMOC, but because the latest one has yet to be peer reviewed we should do nothing and ignore all the warning signs

    IDK, maybe just this once we act early. What's the worst that happens, we reduce pollution a bit? We invest too much into scientific research?

    I get that it's easy to to jump to conclusions online but you literally have me all wrong. I work in researching carbon sequestration. As already mentioned in a different comment reply, I'm happy that people are researching AMOC and the consequences its weakening will bring. But, there's a very big difference between saying, "AMOC is weakening and may collapse at some point if things don't change", and "we're already past the point of no return". One is a helpful statement, the other just drums of despair, which isn't a helpful emotion for tackling climate change.

    If you look at the pre-print, its written to my eyes in a somewhat unscientific manner relative to most other climate publications, and so I kind of doubt its rigor. If you want an in-depth review, https://www.annualreviews.org/content/journals/10.1146/annurev-marine-040324-024822 presents an update article on why exactly making this sort of conclusion is difficult.

    The AMOC has been in a lot of trouble for years now. Ironically, it was the cleaning up of shipping cargo oil that may have put the final nail. We stopped using a fuel that emitted SO2 into the atmosphere, but that SO2 actually ended up as a sort of shielding from the full effects of the greenhouse effect happening elsewhere over the Atlantic. Without it, temperatures this year and last year absolutely soared

    Oh definitely, there's a lot of troubling outcomes and I'm glad the research is being done. I just think news reporting on unreviewed results is good for nothing other than fear mongering. And it's not like that has been effective for other consequences of climate change. Giving people more reasons to 'give up' won't help solve problems.
