NEW: A lot of bad has happened to American science over the last year but nothing comes even close to what’s about to happen if we don’t speak out in opposition to the OMB rule changes and I hope @aaas-socsci.bsky.social @apsphysics.bsky.social and others will launch public campaigns about this. 🧪🔭⚛️

It's the End of American Science As We Know It

We have 45 days to express our opposition to catastrophic changes.

Join us online Thurs to hear what Mia has learned about lake microbial ecosystems & climate change in Greenland & Arctic Canada. V cool methods & findings! (Also, Mia is seeking postdoc opportunities. It's hard out there in U.S. science right now. Add a GREAT geochem/paleolimnologist to your group?)

Flyer for the PhD defense of Mia Tuccillo at Northwestern University, defending a dissertation titled "Integrating Sedimentary Pigments and Genetic Signatures to Track Holocene to Modern Microbial Ecosytems and Implications for Water Quality in Warming Arctic Lakes." Contact Yarrow if you want the url to attend this event virtually.

Fab new review alert! 🔥🤓 There's so. much. data compiled here in one place! ⚛️ On so many different water isotopes proxies. Should be very useful for old hands and water isotope rookies alike. It was so fun to contribute a tiny piece to this joyously epic & careful review led by @isotopes.bsky.social

A deep dive into a suite of water isotope proxies, many thanks to this great team: @yarrowaxford.bsky.social Bryan, Gabe, Wil & Jeemin

175 U.S. scientists who do research in Greenland have already signed our Statement from U.S. Scientists in Solidarity with Greenland. With more signatures coming every hour. Greenland belongs to the people of Greenland.

Greenland is a peaceful democracy, and it belongs to Greenland's people!! "We have been America’s close and loyal friend for generations,” Greenland's democratically elected prime minister Jens-Frederik Nielsen stated today. "Enough is enough. ... Greenland is our home and our territory.”

Thrilled to be in beautiful Nuuk for Greenland Science Week. What a special place. And what an opportunity to learn from Greenland's scientists & community members. Qujanaq/tak to our hosts: Arctic Hub, Asiaq, Ilisimatusarfik, Grønlands Naturinstitut. (Colleagues who are here, let's connect!)

New paper on Iceland! Over the last 20+ years, we've analyzed a bunch of high-resolution datasets from a small lake first studied in the early 90s. If you're interested in Holocene climate, tephra, algal pigments, and Norse settlement, this one might be for you: cp.copernicus.org/articles/21/...

High-resolution Holocene record based on detailed tephrochronology from Torfdalsvatn, north Iceland, reveals natural and anthropogenic impacts on terrestrial and aquatic environments

Abstract. Open questions remain around the Holocene variability of climate in Iceland, including the relative impacts of natural and anthropogenic factors on Late Holocene vegetation change and soil e...

MA-based or -trained climate & earth scientists: How has the ransacking of NOAA, NSF, or USGS affected you? I'll be in DC in 1.5 weeks, meeting with our MA senators & staff to advocate for climate & earth sciences. I can share your story, anonymously if you wish. 👩‍🔬 🧪 🌧️ DM/email me & pls repost! 🙏

Earlier this week, I published an op ed that means a lot to me -- because it was for the newspaper I read in rural Maine as a kid. The slashing-and-burning of our federal government is going to hurt rural Americans very much. (There's a piece of good news from Maine at the end of this thread!)

Screen-grab of a newspaper headline for an Op Ed, titled "DOGE is taking a sledgehammer to science, and that is hurting Maine". There is an accompanying photo of someone measuring a scallop's shell, aboard a fishing boat.

This is going to hurt science. 🧪 What hurts science hurts healthcare. 🩺 What hurts healthcare hurts you. 🫵 Call, email, and if possible visit, your representatives. This is personal whether you want it to be or not.

This morning, the US National Science Foundation fired 168 employees, approximately 10% of its workforce, for no cause other than they were the agency's most recent hires. 🧪 Co-workers are leaving supportive messages before they have to clear out of the building at 5 p.m. Sent to me by a source ⬇️

Handwritten notes on a metal table at the National Science Foundation, 2/18/25. The messages include "You deserve better! Thank you!"; "Thank you colleagues! This RIF is WRONG. These orders are immoral & illegal"; and "Your service will forever be remembered and deeply valued - ENG directorate".
