Major reversal in ocean circulation detected in the Southern Ocean

Be warned, this article is misleading. The actual scientific paper shows a salinity‑driven weakening of stratification that likely allows more subsurface heat to reach the surface and melt sea ice. The article describes this as a complete overturning‑circulation reversal with dire carbon release consequences. These are claims that the paper itself does not make or substantiate. The paper actually does not use the words carbon or CO2 even once. The authors of the article took such liberties with this that I really believe this should be considered disinformation.

The article is about the overall findings and their implications, not just the specific paper istelf. Scientists will always be conservative in what they publish, scoping it down to the minimum interpretation that is supported by their evidence. The article directly interviews authors of the study and quotes them, eg:

> We are witnessing a true reversal of ocean circulation in the Southern Hemisphere—something we’ve never seen before,” explains Antonio Turiel, ICM-CSIC researcher and co-author of the study.

If you incorporate these statements it seems quite reasonable to me. You can argue with the author of the study saying that but I can't see an issue with an article reporting that they did, if that's what actually happened.

He's the only that says something that drastic in the article, and he's a physicist, not a climate scientist. The other two comments are from telecommunication engineers. I'd wait a bit to see what the general climate science community has to say about the study. Based solely on the facts reported in the paper I'd say the most worrying point is precisely that we don't know what's going on.
