A new paleoclimate study links stronger ocean stratification to past ‘lukewarm’ interglacials, but points to lower ocean carbon sequestration in the future.

Enhanced deep Southern Ocean stratification during the lukewarm interglacials - Nature Communications

Lead (Pb) isotopes from a ferromanganese crust reveal that during lukewarm interglacials before the Mid-Brunhes Event, stronger deep Southern Ocean stratification limited CO2 release, helping keep atmospheric CO2 levels lower.

I too was warned about the possibility of this kind of thing happening. This was the first time I have seen it so explicit, though. I don't even know the authors of this particular paper! Lots of people have found my work useful, so I am not bothered by this.

In September, I participated in The Ark of Coral Reefs cruise, which commemorated the 10th anniversary of the Kikai Institute for Coral Reef Sciences. I have written a blog post about the first day of the cruise, including why I think Kikaijima is so interesting. raisedbeaches.net/2025/10/05/t...

Tiny fossils called foraminifera lie buried in marine sediments.
Their shells display astonishing diversity from spiraling forms to chambered clusters and even architectures that resemble miniature buildings.
But what if this morphological variety could be explained by only a few simple rules? 1/n

Kikaijima is an island in southern Japan that is rimmed with coral reefs, but it is the fossils of corals that are everywhere on the island that really interests me.

Believe me, I really doubt it was a mistake.

Have you ever read a paper where it is obvious that they purposely ignored your work, not even citing it, despite the obvious connection to it? They even cited a paper that commented on my paper. I am more amused than anything, but I was wondering if anyone else had this experience. #AcademicChatter

As someone who first started on the Internet in the late 90s, this is how it was back then. You have to explore to find people who have shared interest. I think it makes for a healthier Internet, because we have more control over what we see.

All that said, my posts on Mastodon usually get shared more there than on Bluesky, even though I have 3 times the followers here. The audience is smaller than it appears.

After what happened to Twitter, and what I see is happening to Bluesky, my perspective is that having a big public megasite run by American tech people is not a good way to have discourse. A smaller network of people with similar interests leads to a more rewarding experience.

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

I watched the Star Trek: The Next Generation episode "Family" last night (one of the best in the series). They make it pretty explicit in that episode that geophysics must be a required subject for Starfleet officers. #StarTrek
