Whether global warming has affected the strength of this overturning circulation over the past century is still debated: observational studies suggest that there has been persistent weakening since the mid-twentieth century, whereas climate models systematically simulate a stable circulation.
The climate models we all know and predict how climate change will affect us all seem to work on the basis that these currents have a stable circulation that doesn’t change, which doesn’t seem to be the case. Therefore the climate models we’ve known until now might be wrong… and things could be even worse.
I’ve seen a couple of articles from earth.com shared lately and they always have this clickbaity sensationalist tone. I don’t like it.
Looking at the original publication this article is based on I don’t understand much (I’m not a climate scientist myself), but one sentence stands out:
