Southern Ocean Circulation Reversed

Again? Well that's good.

> This change in water composition suggests that the deep ocean circulation in the Southern Hemisphere — known as the SMOC — is not only being altered, but has reversed. That is, instead of sinking into the depths, surface water is being replaced by deep water masses rising to the surface, bringing with them heat and carbon dioxide (CO₂) that had been trapped for centuries.

This is coming on the heels of David Suzuki stating in an interview that he no longer believes we can beat the momentum of climate change (adding that the best we can do right now is likely just hunker down), all while politicians in the US blame floods on anthropogenic climate change in the stupidest way possible -- by trying to pass legislation to ban chemtrails and weather control machines.

All three of these things, in the span of just a few days.

This is a grim, but just as importantly deeply stupid time to be paying attention to the climate. I'm having a hard time finding an optimistic angle about all of this right now.

I suspect this won't be up here long, HN has a pretty strong but unofficial and "community" enforced policy against bad news, especially relating to climate.

But that won't be an issue for long since climate change data will soon continually start disappearing. I seriously never imagined that we would lose Mauna Loa [0], which we might.

Given that even in this community, which is relatively data/science literate, there is enough energy to remove this content during a time when information is plenty, in just a few short a few short years, and in the absence of data, I suspect most people will revert to completely misunderstanding and underestimating the truly existential risks we are facing, despite the observable evidence being more clear than ever.

Already I've noticed in the reporting of the most recent Texas floods there is scant mention of climate change (sure you can find it if you look, but it should be the headline)

edit: as predicted, it's already gone!

Critical take: https://wattsupwiththat.com/2025/07/06/ocean-reversal-hyster...
radixdiaboli•2h ago
This isn't a critical take, it's a cynical one. It's a climate change denial site. Suggest not bothering to follow this link, it's intellectually lazy. The central claims that the article's information isn't anywhere in the study. Which is misleading: the researchers have said these things elsewhere about the research in the study.

Just for the chuckle value, a critical critical take:

The linked IEF article isn't the source, simply one of many secondary media reports on a specific paper.

The source is this paper: https://www.pnas.org/doi/10.1073/pnas.2500440122#tab-contrib...

the #tab-contributors modifier should open a tab for you with a list of authors and their affiliations.

The two principal institutes supporting that study reported by the paper are the National Oceanographic Center (NOC, United Kingdom) and the Institut de Ciències del Mar (ICM-CSIC).

I was interested to know how they measure water salinity from space, but the ESA page isn't very informative.
