Uhmm - not actually the Gulf Stream but the AMOC. Imprecise wording. The AMOC contributes about 15 million cubic meters per second to the Gulf Stream, the latter totals 90 million. However, the AMOC delivers the bulk of the heat transport to the north, so it is what seriously matters to climate. Full explanation what I think about the new study here: https://www.realclimate.org/index.php/archives/2023/07/what-is-happening-in-the-atlantic-ocean-to-the-amoc/ https://www.theguardian.com/environment/2023/jul/25/gulf-stream-could-collapse-as-early-as-2025-study-suggests

They’re on mastodon (super cool!): @rahmstorf@fediscience.org. Tis is a post of theirs which has a link to an article on their blog (link here), which is fairly thorough and detailed and succinct.

I haven’t been following this or climatology, and last I checked (ages ago) it was thought this Gulf Stream thing was very unlikely. I found it striking to read Stefan’s opinion that it really isn’t like that.
