Reposting this because I forgot 🌊 and 🧪.

My point is that it is bedrock scientific fact that marine biomass for consumption is not CDR, so studies making that particular assumption should not pass peer review or due diligence.

Thanks to @jaytcullen.bsky.social for the reminder.

A fundamental fact should have stopped the original publication in its tracks: The organic carbon in oyster biomass is not mCDR.

We eat it, use it, and exhale most of it as CO2. That's what animals do — organic carbon in, carbon dioxide out. What we don't use goes to sewage —> greenhouse gases.

As James says, this isn't even about climate.

It's about all the tools, platforms, models, datasets we use to study and forecast weather and understand how it impacts people, too.

Dismantling NCAR @ncar-ucar.bsky.social is a bad decision for many reasons. NSF’s investment in NCAR scientists, technical staff, facilities and research products supports and catalyzes atmosphere, ocean, and Earth system science across the nation and world with a substantial ROI.

The question about additionality stands, but more importantly, what about the foundational assumptions: 1) All of the carbon in oyster biomass is sequestered from the atmosphere for decades (false - it is respired), and 2) All of the sedimented organic carbon is permanently buried (evidence?).

🌊 Post from Jay Cullen took me to the PNAS article on oyster farming as mCDR. Seems that farmed oyster biomass is counted as sequestered carbon for climate change mitigation. No mention of what happens to oyster carbon after we eat it. Maybe I read it wrong.

If due-diligence of mCDR investors included solid engagement with expert ocean scientists like Hurd and others – who have years of experience and publish peer-reviewed research – the cycle of hype and waste might be replaced with a better path to solutions.

The arguments about uncertain global effects and limited efficacy have been supported by others for years.

One more thing: if harmful blooms or hypoxic fish kills happen anywhere that is influenced by OIF, legal fingers will point, deservedly or not.

The US does not stand for freedom and democracy any more, but is sliding fast into tyranny. Harvard is punished for standing up to this.
If you’re in the US and not doing something now, soon you will be unable to do anything.
We know this from experience here in Germany.

Carbon, climate, and a Royal honour: Professor Boyd recognised for ocean science leadership

Congratulations to Philip Boyd FRS!

FYI, he is a leading expert on marine CDR. His publications have revealed what we know, what we don’t, and what we must learn and do before proceeding with ocean manipulations.

Essential science that can cut through hype.

Exclusive: NSF stops awarding new grants and funding existing ones US science funder also plans to screen grant applications for compliance with ‘agency priorities’.

🔔BREAKING🔔

The NSF has frozen all research grant awards—cutting off life-saving science midstream and demanding ideological screenings for future funding.

This is censorship disguised as oversight.

I was in the process of hiring a postdoc, so this severely affects her career because now she has to look for something else. It also means I can't pay my existing people, can't buy supplies for the lab, and can't travel. Every NSF-funded researcher will be in the same boat soon.

Delighted to see that Scott Doney has been honored with election to the NAS. His research represents truly interdisciplinary oceanography at its best, he has been a standout in public service, and (dare we say this about scientists?) he is a model of generosity and kindness.

Congrats, Scott! 🌊🧪

The Act prohibits actions that “harass, harm, pursue, hunt, shoot, wound, kill, trap, capture, or collect” endangered species. Right now, “harm” includes damage to a species’ habitat—but the Trump administration is attempting to strip habitat destruction from that definition.

Last minute US intervention at IMO threatens to derail climate negotiations The US has dropped a diplomatic bombshell on the pivotal international talks due to agree shipping’s decarbonisation regulatory measures. The threat of action against member states agreeing to a deal has the potential to derail talks

As we watch Trump's attack on universities, remember that Poilievre promises to appoint a "Free Speech Guardian" for universities.
A university could lose its federal funding if this politically appointed "guardian" recommends it.

Thanks for the heads-up, Clark. A keen student could learn a lot by modelling the interactions between ambient irradiance spectra and LDR sensor spectral response in different water types through the open ocean. Could be a good publication!
