excited to share that we are following through on our earlier commitments and putting together an independent+neutral organization to house the DID PLC system, includes the directory service

Okay okay back to feature writing.

I don't see any language in there protecting the Nathaniel Palmer research icebreaker, however.

It also specifically calls out continuing NOAA Research (OAR) at current levels, "including for research laboratories, cooperative institutes,and scientific awards," and renewing cooperative agreements.

Just in from the @planetarysociety.bsky.social: The counter CR proposed by the Dems to keep the government open includes language protecting NASA missions in "operation, including extended operations, or under development or formulation."

This is not in the CR proposed by House Rs. So we'll see.

I've been asked a few times over the last few days what I think the chances are that the "leopard spots and poppy seeds" on Mars will turn out to be actual evidence of life. People are naturally skeptical given the history of possible signs of life on other planets. Strap in: long thread ahead...

I'd love to follow other early-career and early-ish-career science journalists on here.

Who's out there? What do you write about?

Please say hi and maybe post a recent story you're proud of — or shout-out someone who's writing great stuff.

Online chatter suggests that the DOE Climate Change (Denying) Working Group has been disbanded and the report will be withdrawn. 😂

Seems that violating FACA and the Information Quality Acts have consequences.

Not seen any official announcement though.

Sorry to miss the debunking and deflating fun on Mars rocks. But this story from last July on this same result is still as relevant today.

NASA says it found possible signs of life on Mars. There are a lot of maybes

What's more newsworthy: a NASA briefing about analysis of a Mars rock sampled by Perseverance, or that the briefing will include Sean Duffy, who has not participated in any NASA pressers since being named acting administrator 2 months ago?

In the 1st half of 2025, @climate.noaa.gov 's staff were terminated, shutting down daily operations.

Now, former members have joined w/ nonprofit partners to launch Climate.us, where climate info can be safeguarded from politics.

Check out our website and join the effort today.

Every climate model out there has a different AMOC sensitivity to the relatively freshwater introduced by the pacific water flowing in to the North Atlantic (it’s about a psu less).

But wait - how does that scale with the freshwater input by arctic rivers. (Half as important PI) -

My latest looks at an audacious new geoengineering proposal: Damming the Bering Strait to save the Atlantic's overturning circulation from collapse.

It would bring all the ecological, social, and political problems -- and it could cause the collapse it's trying to forestall. (Or not.)

Could a giant dam save the Atlantic currents that keep Europe warm?

Geoengineering scheme that would block the Bering Strait could kill the ocean circulation it’s meant to protect, researchers warn

Yup. (And while I'm not well-sourced on the military, I can only imagine what the Navy would think about it )

Note also: it's a very open question if AMOC would ever collapse, rather than gradually weaken.

And as always with geoengineering, the first best answer is to not do this -- and curb CO2 emissions instead.

I'm not a scientist and didn't any interviews on this, which is the terrain I'm more comfortable on, so take it all with a grain of salt and I'd be happy to have anyone correct me.

1

Paul Voosen @voosen.me · Sep 5

It's a big big scientific question whether TWS will recover back to the levels seen before the 15/16 El Nino or whether the decline is tied to temperature rise since then and there's no going back -- and whether that 10% contribution to SLR will therefore grow.

1

Paul Voosen @voosen.me · Sep 5

For example, this pub late last year led by the GRACE/FO hydro guru Matthew Rodell found that 20-year decline in TWS was dominated by Asia, "largely driven by drought and exacerbated by human extraction of groundwater."

1

Paul Voosen @voosen.me · Sep 5

The caveat to the study is that GRACE can't partition how much of the drying/wetting trend is GW pumping vs other factors. That's done through hydrological modeling. That doesn't mean its wrong--GW extraction is *definitely* part of it! But I'd be more cautious in how you use it.

1

Paul Voosen @voosen.me · Sep 5

Sorry, was on deadline. Trying to separate the importance of drying vs wetting regions for a global phenomenon (sea level rise) seems bound to confuse. The non-glaciated continents contribute ~%10 to annual SLR, less than the glaciers and GIS/AIS individually.

This is incredible work.

In a just world it would win some major reporting awards. I’m saying that now bc I don’t think it will. There’s a particular kind of scoop you only get by being a really effing good beat reporter for a long time who sources trust. Investigative reporting doesn’t prize that.

Brown is the dryer areas and blue is the mostly counteracting wetter areas. Red is the melting glaciers. There's nothing to counter that.

Groundwater pumping is totally an important issue! But this framing seems a little problematic.

1

Paul Voosen @voosen.me · Sep 4

A lot of people are being misled by that paper. They separate the continents into areas getting dryer or wetter -- but then only emphasize the dry while leaving out how the wetter areas are subtracting from SLR.

Look at this graphic from it.
