Abstract submission for Life and Planet 2026 is open! Come explore the co-evolution of life and the Earth with us:

252 million years ago, Earth faced its worst extinction. Now scientists have found the same chemical signals in rocks from Iran and South China, nearly 5,000 km apart. The message is clear: the end-Permian crisis wasn’t local chaos. It was one connected planetary event. 🧪 #SciComm

Really interesting mechanism here I think: thousand-year orbital cycle modulation can drive million-year pulses in nutrients, oxygen and (we hypothesize) biodiversity during early animal evolution OA paper out today: agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Googled the title of our new paper out today and the FIRST HIT was an AI sludge article that was completely incorrect A: no we didn't analyse phosphorus isotope ratios in rocks B: NOBODY analyses these C: because phosphorus only has ONE stable isotope Dead internet here we go

Public talk this eve at the wonderful Seven Arts bar! I am reliably informed there will also be jazz! www.sevenleeds.co.uk/events/

There’s an interesting series of 5 free online paleobotany lectures via the Oxford University Botanic Garden this autumn. You can book all 5 lectures here (scroll down webpage to ‘Get your tickets now’ button) www.obga.ox.ac.uk/event/dr-san... #paleobotany

New palaeo-PhD opportunity! Will you be the one to figure out the anatomy and function of fossil jawless fish? Come join the team! Application Deadline August 22nd, funding for UK student only (sorry) www.findaphd.com/phds/project...

🚨Job offer 🚨 Postdoctoral position in micropaleontology opened in our team!

Hi Goldschmidt! Catch my Berner Lecture at 2.30 today!

Check out this cool map of sea level variability due to glaciation over geological time. Awesome to be involved in this work led by Douwe van der Meer open access paper here: www.sciencedirect.com/science/arti...

Great to see this finally out today! We show that the collapse of tropical vegetation during the Permo-Triassic extinction is a key driver of the long-term super-greenhouse climate that followed it. Read more at www.nature.com/articles/s41...

Talking about the deep past and deep future of the Earth today at @sotonoceanearth.bsky.social / @noc.ac.uk Seminar at 3pm!

Did flood basalt weathering draw down significant amounts of CO2 in the Mesozoic? We think not so much: www.nature.com/articles/s41...

Registration is open for Life and Planet 2025 on July 14-16! lifeandplanet.com £60 (student/GSL fellow) £80 standard Hope to see you there!

Registration is now open for @lifeandplanet.bsky.social in London July - 14th -16th. A nice conference for ECRs working on all aspects of the co-evolution of life and the Earth's surface. #geology #paleontology lifeandplanet.com

How can zombie microbes interact with the Earth system? 🦠🧟🌎 Microbes, even when dormant, play a massive role in shaping Earth's ecosystems & biogeochemistry 🌎 In @natcomms.nature.com I explore dormancy in the context of Earth’s geosphere-biosphere co-evolution 🧵👇 www.nature.com/articles/s41...

The best part about running a conference is knowing that everyone else also leaves their submissions to the last minute! PS: Life and Planet 2025 abstract submissions are extended for another week, so if you missed it you are not too late! lifeandplanet.com

Excited for Life and Planet 2025 in London this July - please don't forget to submit your (free) abstracts! lifeandplanet.com

🌎🦠🐚🧪🌏🧬🌳👽🌍 Interested in the co-evolution of life and our planet? Life and Planet 2025 abstracts are still open until 9 April! The meeting this year will be 14-16 July. Students and early career researchers especially encouraged! lifeandplanet.com @lifeandplanet.bsky.social

FYI if you are using language models for research: Here's Chat 4.5 making a series of totally incorrect - but plausible to a nonspecialist - claims about our work:

The SCION Earth Evolution Model is turning 4 years old this spring. We have celebrated by extending the framework back to ~1 Ga before present We find some agreement with broad environmental trends from the rock record, but there is still plenty to learn! www.sciencedirect.com/science/arti...

Well done to the brilliant Leeds postdocs!

A FINAL REMINDER that the abstract deadline for The Geochemistry Group Research in Progress meeting (GGRiP) is MIDNIGHT TONIGHT. This will be a great meeting! Visit ggrip2025.co.uk for more information and to submit your abstracts.

"The Phanerozoic has experienced two major icehouse periods, the late Paleozoic and late Cenozoic (our current geologic era). The new model was able to reproduce both of those icehouses, as well as periods of warming in between" ⚒️🧪 eos.org/articles/how...

Come and join me in Marseille ☀️🌊🐟🔬🇫🇷🇪🇺

An amazing honor to get this award last night! Huge thanks to the New York Academy and Blavatnik Family Foundation!

Giving the Astrobiology and Planetary Habitability (APEX) seminar at UCL room G22 at 1pm today! All about oxygen!

Multicellular fossils from ~790 million years ago show green algae were well established in Tonian, before "Snowball Earth" episodes ⚒️🧪 www.lyellcollection.org/doi/full/10....

Going to Prague for Goldschmidt this year? Come to London the Monday-Wednesday after for the Life and Planet 2025 meeting Abstract submission open NOW! lifeandplanet.com

Exciting!

Over its multimillion-year history, multiple planetary cooling mechanisms working together were required to push Earth into 'icehouse' conditions and to form ice caps. See our new paper on this here: www.science.org/doi/10.1126/...

This is officially my horizontally longest image to date, depicting some of the earliest complex animals on the planet from 565 to 505 million years ago and how they changed over time. Thank you to @egmitchell.bsky.social and Steve Pates for trusting me with this gargantuan task! #Art #SciArt

Excited to be speaking about marine deoxygenation in the past and future at EGU 2025. Please consider also submitting to the session!

Hi ETH! See you for the GFD seminar at 12pm! I'll talk about Earth Evolution Models and our planet's environment in the deep past, the deep future and what this means for finding other habitable worlds

Arrived. Honestly better than flying. I am about 3 hours later than i would have been on a plane, but i have done basically a full day of work in peace and quiet.

Leeds to Zurich via train lets go! Can i convince you to quit the plane to Europe?

Save the date! Life and Planet 2025 will run on 14th-16th July (the week after Goldschmidt) in London! More at lifeandplanet.com
