🚨📜🚨 What did the western Siwalik landscape look like ~1.2 million years ago? Led by A.P. Kaur, we ([email protected] et al.) have a new paper out using #fossil teeth from the Haro River Quarry—a hyena den—to reconstruct #mammal diets & #vegetation during the early #Pleistocene 🦷 🌾 🔨 (1/4)

This is sad news 😥 I was fortunate to have overlapped with Dr. Ramaswamy during one of his visits to the Indian Institute of Science in Bengaluru—I was grateful for his perspective and time on many things scientific and otherwise. Om shanti.

Hey earthquake types - Swiss Re is hiring an entry grad level earthquake catastrophe modeler. Strong science shop if this is your thing:

My colleague at @au.dk Geoscience has a PhD position open. Apply by August 1 if you like cosmogenic nuclides, paleoclimate, and desert (and/or dessert?) formation! Perfect for students who are looking for a combination of labwork and very exciting fieldwork... phd.nat.au.dk/for-applican...

📜📜 Led by P. Saravanan, we have a new paper out that shows how changing Holocene #monsoon winds shaped mixed-layer #ocean dynamics in the Arabian Sea 🌊 🔨 As early-to-late Holocene Indian summer monsoon winds weakened, they churned the Arabian Sea less and less... 🧵 www.nature.com/articles/s43...

www.nytimes.com/2026/06/18/c... Some good news on OOI 💙 While this reads as “problem solved”, many ocean (particularly AMOC) observations are not in calm seas yet. Currently we’re dealing with issues with Canadian moorings. All around, founding is running out and/or uncertain.

A phenomenal finding!

It's out. My latest feature for @science.org, from aboard the RRS Discovery: a deep look at the past, present, and future of AMOC, told through the RAPID program. AMOC is weakening -- maybe, probably. But it also may be more resilient than some have made it seem.

Excellent summary!

New Global Cave Monitoring Database: Insights into Drip Rates and Isotopes The PAGES-SISAL (Past Global Changes – Speleothem Isotope Synthesis and AnaLysis) team has created a new global database of cave monitoring data consisting of drip rates and drip water isotopes, and the modern carbonate…

Moonlight sonata. I took one of my favorite photos last night. While looking for a scissortail, this eastern meadowlark perched itself atop a nearby tree and sang a beautiful song just long enough for me to position it directly in front of the nearly-full Moon. #Photography #BirdOfTheDay #Birds

Interesting responses from the mathematicians who verified this work (at the end of this document): cdn.openai.com/pdf/74c24085...

Not entirely sure how to feel about this, but nevertheless, this is remarkable: AI has helped solve an important problem in mathematics—the unit-distance conjecture—formulated by Erdős ~80 yrs ago, based, apparently, on one single prompt 😳 www.nature.com/articles/d41...

The future of drought isn’t just less rain. Climate change can make land drier even if rainfall doesn’t decrease. Why? Rain is falling in fewer, heavier bursts - causing more runoff + evaporation, and less water stored in soil. www.nature.com/articles/s41...

I wonder if this year is an #irruption year for Diamondback Rattlesnakes in southern Arizona—have anecdotally heard abt several encounters recently (or perhaps it’s just seasonality) #Western #Diamondback #Rattlesnake This one seen at #Sweetwater Wetlands in #Tucson

Monthly ebook releases on Amazon were basically flat before the release of ChatGPT and other LLMs. Now around 2/3 of all ebooks released on Amazon are fake.

This is absolutely tragic 😢

This is a FRAUDULENT paper, AI-generated. My name was used as an author and I had nothing to do with it, never saw it until today e-pubmed.co.uk/journals/dig... The "Editors" Angelo Rossi Mori, David Mensah, and Zarnie Khadjesari and this "Journal" should be reported.

Japanese Earth science word of the day: 有孔虫 (ゆうこうちゅう - yuukouchuu) - foraminifera. Foraminifera are single celled organisms that secrete a carbonate shell-like "test". Foraminifera fossils are abundant in marine sediments and are used extensively in paleoclimate research.

⚒️🌋🌊🦠(🐋)📉❄️ In a new paper we hypothesize that explosive volcanism in the Andes, some ~10–6 million years ago, “fertilized” the nutrient-starved Southern Ocean, with nutrient-rich ash that may have stimulated enormous plankton blooms & marine ecosystem changes. Link: www.nature.com/articles/s43...

El Nino thread! Buckle up! I'm turning all the things I'm muttering to myself into a thread.

Happy publication day to me! I am very excited to share that my first chapter of my PhD has been published in Climate of the Past today. cp.copernicus.org/articles/22/...
