Pulling sun-warmed water up from the tropics towards Europe and the Arctic, where it cools and sinks, it forms a deep return current heading back south.
This system has already been shown to be at its weakest in about 1,600 years because of rising global temperatures, and scientists flagged warning signs of a possible tipping point back in 2021, so it’s not like this has come out of nowhere.
