After over a year of record-high global sea temperatures, the Atlantic is cooling off more quickly than ever recorded, which could impact weather around the world
This. I work at a research lab and we don't know shit about shit. Sure, we can gesture vaguely at anthropogenic climate change, but that doesnt get you published.
The fact that it's probably several different climate-induced processes causing the change makes it very difficult to establish causality. All we know definitively is that shits fucked
I would have assumed it was due to a weakening of the North Equatorial/Gulf Stream Current. the IPCC Sixth Assessment said that would be a thing that happens, though it probably wouldn't collapse entirely.
even so, a weakening would have dramatic impacts.
kinda surprised it isn't mentioned in the article as a "maybe" or whatever.
