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 💪

I saw press coverage of this today, and didn't have time to click links - didn't realize it was you guys! Congrats to Andy and team on the nice work. 👏

This research (and training of the next generation of scientists) was funded by the US National Science Foundation. Americans can stand up for science by asking their Senators and Representatives in DC to support NSF and American science. It's urgent to call this week, especially. Thank you!

I should clarify that cyanobacteria are cool, common in Arctic lakes, and not necessarily yikes. What's yikes to me is the speed and intensity of changes driven by just a few degrees C warming ~6600-3500 years ago. Alongside (from other studies) major glacier loss & species migrations. Big impacts.

Mia is a highly talented PhD student approaching graduation at a tough time for U.S. science. I have to highlight another neat thing she's been up to: Art/science/community collaborations in the very special south Greenland town of Narsaq: www.miattuccillo.com/community-ou...

Note that @isotopes.bsky.social (with other methods) found that lakes lost hypolimnetic oxygen in three more (far-away) sectors of Greenland around the same time. Oxygen depletion was apparently widespread, in response to a few degrees of summer warming. www.science.org/doi/10.1126/...

Aquatic plant wax hydrogen and carbon isotopes in Greenland lakes record shifts in methane cycling during past Holocene warming

δ2H values of aquatic plant wax reveal past Holocene warming led to expanded CH4 cycling in lakes across Greenland.

Mia painstakingly extracted photosynthetic pigments from 7,000-year-old sediments to figure this out. Super cool! (3/3) Gift link here: authors.elsevier.com/c/1lrE5-4PSD...

Links between warming and lake-water quality are especially important in Greenland, where communities use rivers and lakes for drinking water. Congrats Mia, and thanks to Greenlanders for access to our research sites! 🙏 (2/3)

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/...

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...

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

We want to hear from current and former federal workers from New England

Are you a current or former federal worker in New England affected by the changes being made by the Trump administration? If you're willing to share your experience, we want to listen.

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! 🙏

DOGE is demolishing American science, almost overnight. Maine’s bipartisan team of DC Senators and Representatives have power; and Mainers can tell them to stand up for science, stop the firings of federal scientists, and continue funding research. -END

On its own the National Institutes of Health, which funds medical research, granted $125 million in 2024 to projects across Maine. Federal science funding like that is tough to get, but it supports good jobs for Mainers, supports a wide range of Maine industries, and supports

Grants train young scientists and create jobs, but they are no gravy train. Research universities are nonprofit employers, and every research-active scientist I know works long hours. My friends work on understanding cancer cells and finding cheaper ways to clean up toxic chemicals.
