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!)

TIL that the feminine plural of "bravo" (applied to a group of women or girls) is "brave" - and now I want to use this word all the time 💪

New paper! PhD student Mia Tuccillo has uncovered another big impact of past warming in Greenland: lakes lost oxygen for thousands of years and cyanobacteria took over 🦠 🧪 🦠. It's kinda yikes... With collaborator @geobiomaggie.bsky.social (1/3)

This title from @peterbrannen.bsky.social! 🤩 If only I were better with words, this could have been the name of ALL my climate and Earth history courses for the past 15 years... because yep, everything circles back to CO2. Even when we really wish it didn't. Looking forward to reading.

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/...

One week left for US researchers and practitioners to respond to the call for experts for the IPCC Seventh Assessment Report!

🚨Calling U.S.-based climate experts! The newly formed U.S. Academic Alliance for the @ipcc.bsky.social is now accepting nominations for the Seventh Assessment Report.🌍 Join a global network of scientists shaping the future of climate action. Apply by April 4: buff.ly/hDrBH1F #IPCC #AGU

The conversations we've had with workers have helped us explain how the layoffs will affect Americans in New England and beyond.

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! 🙏

If you’re protesting this weekend, know your rights.

Upper-level weather balloon launches at three different #NationalWeatherService forecast offices in New England will be missed intermittently until further notice, per an NWS bulletin issued this afternoon. 🧵...

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!)

Lots of hard-working climate scientists are suddenly on the job market, thanks to DOGE so recklessly demolishing American science. Great job here for a climate scientist with data and communication skills who is ready to fight back! 🧑‍🔬💪

This is amazing 😍😍 @500womensci.bsky.social has made cards for each state on funding for NSF and NIH avail for download bit.ly/NSF_bystate & bit.ly/NIH_bystate if they are helpful for folks

Some folks have asked, given recent news, “how do I show my friends/family the impact of NSF?” We have some easy Fact Sheets for you! Here’s a brief thread about this website: new.nsf.gov/about/fact-s... which hosts a ton of useful one-pagers.

Great ideas! Let’s be next @agu.org

The AMS is temporarily opening its career services to all who need them, regardless of membership status, and offering dues waivers and meeting registration fee reductions for those impacted by job loss due to changes in the government. Read more: bit.ly/4gRiHAk

Hello—I am looking for first person essays by scientists and doctors that are relevant to the news to run in Slate. Pitches and submissions: [email protected]

You deserve a break from the dumpster fire to enjoy a little dose of happy beauty. Thank you, Canada 💕

US geoscientists: @agu.org is big (you know that from the lines at meetings!) - AND politically connected in DC. Here’s a way to let AGU leaders know how your work as scientists is suffering right now. And to share your career fears, defend DEI, etc. Anonymously if you wish.

For my polar science colleagues beyond the US. Thank you for your support. ❄️🙏

I honestly believe our most powerful position in a toxic time that feeds on cynicism, apathy,& despair is to genuinely care and act for a better world. Cynicism is our enemy. We should check it, incl. on the left. It’s not intellectually superior. It’s the virus they’re trying to infect us with. NO

Important thread. ❤️ Let’s FIGHT the sudden scrubbing of DEI from science like it really matters. Fight for a real meritocracy - which means pushing back against the goals of sanctioned racism, homophobia, transphobia, sexism.

ProPublica reporters are dedicated to investigating government agencies and federal policy. Concerned public servants are some of our most important sources. We appreciate the difficult situations people weigh as they decide whether to reach out. Here's how to securely get in touch.

If you’ve been directly impacted by a pause or cancellation of an NIH study session, we @forbes.com would like to talk to you

If you can write and submit a journal article, you can write and submit an OpEd! Here is a thread of OpEd writing tips for scientists and health professionals. 👇 #ScienceNotSilence 🧪

What can you do? Talk loudly about what government actually does for you. Call your reps and tell them to protect federal research and to make government work for all Americans. Write op-eds. Talk about the medical research that saved your life. Share your stories. Help people make the connections.

We’re doing a story on how to do winter better and we want to hear from YOU! What creative coping mechanisms get you through the coldest, darkest months? Tell us your unique winter survival strategies: Leave a message at 646-767-6532 or send a voice memo to [email protected].

For anyone wanting more fun facts in their (definitely watery) life 💦

I don't generally post about my own work, but if you are looking for a last minute present for the holidays for someone who might be interested in the ocean, my book seems to appeal not only to adults but also to even really little kids. All royalties go to the Smithsonian.

This holiday season, why not give the gift of ultimate cosmic destruction?? 💥🌌 www.astrokatie.com/book Kirkus Reviews calls it “a delightfully unsettling narrative”! @leebillings.bsky.social raves about my “infectious enthusiasm for communicating the finer points of cosmological doom”!

When we did this rather silly comparison picture highlighting glacier retreat in Norway over the last 140 years... I don't think any of us expected it to make it into a news story on the NRK website 😂. Such is life! I ❤️the scratchy image they have at the top: www.nrk.no/klima/brefor...

Hurray for Phd student Aidan Burdick, who presented 2 posters at #AGU24. One analyzed marl isotopes in an Illinois lake to look for (maybe) past drought. Another shared deglaciation ages from New Hampshire - work led by collaborators at Dartmouth. Aidan is becoming a v well-rounded Quaternarist!

From OpenEnviroData: "If you're at #AGU24, visit Esri's Dan Pisut at the Esri booth (739) in the demo theatre area. He and Katie Hoeberling are taking suggestions for federal datasets to archive as part of the Public Environmental Data Project (shorturl.at/I6qlV) " 🧪🌊⚒️

Silicon Valley is like: "How about we make search engines useless and replace them with a cutely named robot who makes stuff up? And also creates more pollution to accelerate global warming?" "What do you think? Never mind, we've already done this for you."

I’ve studied the Arctic for 30 years ❄️ and am still stunned at how fast it’s changing - racing toward new states that will affect us all. We have all the tools to put the brakes on. Keep fighting for that y’all. ❤️

Weds afternoon at #AGU24: come talk Holocene lake-level change, lake anoxia, and super-cool pigments from algae and cyanobacteria with Mia!

Geochemists: add yourselves! (Alas, I am not really one of you. I just really like collaborating with you.)

A great opportunity at a fantastic department - Assistant Professor in Physical Geography @geogdurham.bsky.social. We are looking for candidates with expertise in ice sheets and glaciers that will complement and extend our current work. Closing date 12th January.❄️⚒️🧪 durham.taleo.net/careersectio...

With #AGU24 in full swing, a stripy reminder that Arctic is warming rapidly, and there’s no mystery why. #ClimateChange #AGU2024
