Gregg is a former Marine and Forest Service ranger. He's saved the lives of hikers dangling off a cliff or going through cardiac arrest, and he's bravely fought forest fires to save small rural towns. 100% of his salary is paid by WA state. Elon fired him. Share his story.

Sometimes I miss the old bird site. Jenny Uglow's review of the new Strata book featuring detailed photos of William Smith's culminating work prompted me to write a long thread it would be hard to duplicate now. www.nybooks.com/articles/202...

Today is Charles Lyell's death date (1875), 150 years ago. Lyell was the great popularizer of Uniformitarianism: if we know the circumstances under which particular rocks form, when we see those rocks in the geologic record, we can interpret the processes active in the past.

February 22, 1881 "Cleopatra's Needle", a 3.500-year-old Egyptian obelisk is erected in Central Park, New York. After surviving in the dry desert for millennia, it showed strong weathering in just 100 years caused by the humid climate & air pollution of the city. per-storemyr.net/2010/12/12/c...

The DOGE firings have nothing to do with “efficiency” or “cutting waste.” They’re a direct push to weaken federal agencies perceived as liberal. This was evident from the start, and now the data confirms it: targeted agencies overwhelmingly those seen as more left-leaning. 🧵⬇️

This is what you call robbing the future.

NEW: NIST staffers expect ~500 people—incl. 3 lab directors who were promoted in the last year—to lose their jobs as soon as tomorrow, as part of the DOGE purge, sources tell @wired.com. @willknight.bsky.social, @peard33.bsky.social, and @leahfeiger.bsky.social report: www.wired.com/story/the-na...

Unite! 💪 "Conflicts btw faculty & administrators ... should be set aside to focus attention on this ruthless takedown of academia. All disciplines will be affected by these cuts, not just science. This is a moment to unite." www.science.org/doi/10.1126/... by @holdenthorp.bsky.social

NOAA is reportedly on the DOGE chopping block. The National Weather Service, which is part of NOAA, provides life saving weather forecasting in the US. A study found that for every $1 invested in NWS, it produces $73 in value to Americans. Again, this isn't about efficiency.

Today is one of my favorite days: the shared birthday of Darwin and Lincoln, February 12, 1809. In 2018 we visited Darwin's home Down House, and a highlight was walking the Sandwalk where he walked daily considering the problem he was working on.

I missed posting yday on Intl Day of Women & Girls in Science. The word Scientist was coined in 1834 to describe Mary Somerville by William Whewell reviewing her book On the Connexion of the Physical Sciences. Her portrait on the 2017 Scottish 10£ note #internationaldayofwomenandgirlsinscience

My. God. These people are idiots.

Charlotte Murchison, British geologist married to Sir Roderick Impey Murchison, died #OTD, 1869. She introduced him in the world of geology and was a close friend of Mary Anning. The fossils collected by her were described in the “Mineral Conchology of Great Britain” wp.me/p3ihHu-3Eb #WomenInSTEM

One of my favorite subjects to photograph are these glacial river deltas in Iceland from the air. It is always a surprise what you will see when flying in a small plane but it’s some of the most beautiful abstract art on earth. Here’s a pair from my very first flight many years ago.

These are the seismic stations of the Advanced National Seismic System (ANSS), the majority grant-funded, and operated by universities on behalf of the USGS. ANSS is used for routine EQ processing, its data informs the nation's seismic hazard map, and is the backbone earthquake early warning
