All you foundations and wealthy universities should be funding the rejected proposals from NSF. Get rid of all the overhead associated with having your own funding process. There will be an abundance of highly rated and expertly vetted science that will not get funded as a result of these cuts 1/2

Volcanoes are cool. Except when they erupt and then they’re really hot. Like really hot. And loud. And generally fucking awesome. Highly recommend.

Scientists: Well our best guess for extinction-causing climate change from the Earth History is probably catastrophic cooling associated with stratospheric aerosols. Tech bros: Well that COULD happen but I could also save the world and become a gazillionaire! LFG! Fermi paradox answered.

It’s 😎 to wear helmets kids! Take it from this 😎 dad.

Is Bluesky just LinkedIn light? Are there substantive scientific discussions to be had here? Or just a lot of horn tooting and finger wagging?

Woop woop for N isotopes and a deeper understanding of the origins of Pleistocene glacial cycles!

Serious FOMO over here in the USA while all the new data from Beyond EPICA. Whose got the 🫖 @tinyicybubbles.bsky.social?!

One fun facts about GWPs: those passionately arguing for 20-year GWPs over 100-year GWPs probably would not passionately argue for a 7% discount rate over a 3% discount rate (and might, correctly, think 3% is too high for long-lasting societal risks) yet mathematically these are almost the same

Today I learned what the expression 'soup to nuts' actually means. Makes a lot more sense now, but who eats nuts for dessert?!

Why is it that they always use the stock photo of McMurdo when posting bad news about NSF?! www.washingtonpost.com/science/2026...

My first NSF rejection of the year! The wheels must be turning! I'll have the chance to apply and get rejected again!

A new agreement between TCNJ and Princeton will allow eligible undergraduate and grad students to enroll in select courses at the other institution during the fall and spring semesters at no additional cost: https://bit.ly/4tqr2le

Getting direct measurements of CO2 from Pliocene-aged ice has been a Holy Grail of climate science! A new paper by @jmarkspeterson.bsky.social provides a record of CO2 going back 3million years(!), with (let's say) intriguing implications for anthropogenic climate change doi.org/10.1038/s415... 1/

For the first time, scientists have measured atmospheric gases from the late Pliocene, yielding data that could help to predict the future climate

If this is your scene*, maybe this job is for you? Three-year PDRA in ice core gases at @cambridge-earthsci.bsky.social www.cam.ac.uk/jobs/researc... *Scenes from the Beyond EPICA gas analysis in Copenhagen.

While everyone is (rightly) obsessed with levels of CO2 in the atmosphere 3 million years ago, don't sleep the observation that avg. atmospheric methane (CH4) DOES NOT APPEAR TO HAVE CHANGED AT ALL over the last 3 million years (1/4). www.nature.com/articles/s41...

New results from old ice....happy to answer any questions!

I very much enjoyed listening to this book. It does a great job capturing the links between CO2, climate, oxygen, plate tectonics, and Earth history which are both simple and incredibly complex! Recommend!

Some cool science coming up so I guess it’s time to start posting again?

Would anybody like to read one of my long threads about a 2.5bn year old rock, bacteria that could produce oxygen but not consume it, and tank production in wwii

🚨 New manuscript! 🚨 We use speleothem calcium isotopes and Mg/Ca to reconstruct rainfall amount. Turns out central Vietnam was 50 % drier during the LGM 🤯. Climate models agree but most underestimate rainfall change. www.sciencedirect.com/science/arti...

What’s it like doing fieldwork in Antarctica? 🥶 Sarah Shackleton and @blueicedude.bsky.social from @princeton.edu can answer that. They just found a 6-million-year-old ice core—a key piece to improve our current climate models! My story for @eos.org eos.org/articles/new...

New research from John Higgins @blueicedude.bsky.social & Sarah Shackleton @princeton.edu, comments from Lidia Ferri, story by Mariana Mastache @deerenoir.bsky.social.

⛺️ up! Drill down! Just another day in paradise looking for Earth’s oldest ice.

We've got a new record for the oldest air ever discovered. 💨 Scientists led by Princeton's @blueicedude.bsky.social and Sarah Shackleton uncovered air trapped in ice that is 6 million years old.

🥶 Led by Princeton's @blueicedude.bsky.social and Sarah Shackleton, a team of scientists has discovered the "oldest directly dated ice and air" on the entire planet in Antarctica.

The natural weathering of ALL THE ROCKS in the world removes almost 1 billion tonnes of CO₂ from the atmosphere every year. Enhanced rock weathering is an attempt to use a minuscule fraction of ALL THE ROCKS to remove many times more CO₂.

To be fair trilobites were around a lot longer than humans (250 million years give or take) and were wiped out in the by a great global catastrophe than has some parallels to anthropogenic climate change. They also preserve 😍 fossils. Not so niche to me!

Today those of us funded by @NSF received this memo. Perhaps the most concerning statement: “Therefore, all review panels, new awards, and all payments of funds under open awards will be paused as the agency conducts the required reviews and analysis.”🧪

Had a great visit to the summit of Mount Washington in NH this week to meet with Observatory staff & discuss science & education efforts we are working on together. Not a bad day for some windy weather as well! Peak gusts hit 86 mph. Check out this worthy organization! 🧪 mountwashington.org

Could your next job be in Antarctica? We're looking for carpenters, chefs, electricians, plumbers, plant operators and more to work at our research stations. These are jobs like no other, in one of the most beautiful places on Earth. ✅ Vacancies bas.ac.uk/vacancies 💡 Job alerts ow.ly/fWsu50UJHBP

An ice and rock core drilled 2.8 km deep on the antarctic ice sheet may tell us about the climate record for 1.2 million years - and perhaps even info on the planet going back 2.8 million years. www.sciencealert.com/oldest-unbro...

Agree!

Super excited to share our latest on CO2’s role in geological climate change! Using boron isotopes in ~300 million year old brachiopod shells, we show that rising CO2 from volcanic emissions drove a profound change in climate that ended the Late Palaeozoic Ice Age ⚒️🧪🌊 www.nature.com/articles/s41...

ICE-DAY! Cool layers & melt/refreeze features in ice cores extracted from Thwaites Glacier, Antarctica. We drilled thru ice to collect subglacial bedrock to determine the last time the bedrock was exposed to the sun using cosmogenic nuclide exposure dating. Also, a beautiful ice crystal! 🧪❄️

Delighted to see that MBA Trustee Professor Rosalind Rickaby OBE FRS has been recognised with an OBE in the New Year's Honours List! Ros has been honoured with this high accolade for her services to Biogeochemistry.

🧪🌋 Apparent mystery resolved : early 1800's global cooling was suspected to be cause by an unknown eruption. But it appears that such eruption has been identified. www.pnas.org/doi/full/10....

Do this especially if you’re at a place that can nominally afford to invest in creative folks with big ideas. Most academic institutions have a balancing act that doesn’t give a ton of flexibility on hiring (ie we have classes to teach), but some do! They should do better!

To all your ECRs out there….those who don’t do write reviews! Be a doer. 🧪!

Tim Lenton is a friend, and it saddens me that he found our perspective saddening rather than constructively critical. But: despite his and colleagues efforts to “clarify what they meant by tipping points”, those efforts *have not worked* over the last 20 years, and we need to deal with that.

So many drawers, each filled with treasures

Sad to not be down in 🇦🇶 with @coldex.bsky.social drilling Earth's oldest ice, enjoying ⛺ life and the 😍 scenery. Congrats team!

Personally I have never found the ‘tipping point’ framework helpful for thinking about climate change or how society responds to it. Bob’s paper on this is illuminating.

Happy Isotope Day everyone! 🥳On this day in 1913 Nature published Federick Soddy's paper "Intra-atomic Charge" www.nature.com/articles/092... in which he introduced the term "isotope" (coined after a dinner conversation in Glasgow with Margaret Todd the classics scholar). how will you celebrate?🧪⚒️🌊

Today my amazing colleague, lab mate, and partner @oceanicandrea.bsky.social officially became the first female Professor of Earth and Environmental Sciences @uniofstandrews.bsky.social. Let’s make sure it doesn’t take another 611 years to get the next ⚒️🧪🌊👩🏻‍🔬
