Estimating breakpoints in the Cenozoic Era: an econometric approach Abstract. This study presents a statistical time-domain approach for identifying transitions between climate states, referred to as breakpoints, using well-established econometric tools. Our approach ...

New paper out in @egu.eu's Climate of the Past together with economists (@mbennedsen.bsky.social @erichillebrand.bsky.social) to apply their rate prediction tools to the Cenozoic stack for detecting the timing and duration of breakpoints. Really fun. @au.dk

Velkommen!

On my way back from @uio.no where I served (for the first time!) as a PhD opponent with new pal @sallieburrough.bsky.social. We dug deep into the work of @davidkwright.bsky.social's student (now) Dr. Aljasil Chirakkal on Central Asian Pleistocene paleo-environments. Learned a lot!

Lucky to have gotten the chance to go to URI to see her speak. Because of you!

I'm looking for a driven PhD student to join us at @au.dk and to both generate new paleoclimate data in the lab and work on computational problems to understand climate relationships across timescales.

Get in touch if you'd like to hear more, and apply by Nov 1!

We’ve just started the second week of our summer course ‘Climate Change: Cross-Disciplinary Challenges and Solutions’!

We have experts from different fields visit each day to provide new perspectives on the climate crisis, and students work in groups on case studies from different sectors 🌍

@au.dk

Thrilled (and honored!) that Prof. Cat Beck from Hamilton College visited me at @au.dk during her sabbatical in Cologne. Cat and I have worked in Turkana, specifically on the HSPDP Lake Turkana drill core, for many years. It was great to catch up and talk about fun new things!

We’re in Azerbaijan for field work! I’m collecting biomarker samples from a beautiful sediment sequence in the Azykh cave, where hominins lived over hundreds of thousands of years (we think, lol 😝). Downright honored to be a part of this team in this stunning landscape.

... and will get reviews on their proposals before their 'interview'.

I've been taking the very intense @au.dk pedagogy course this semester, which has taught me the power of constructive alignment, feedback, scaffolding, and more.

I can't wait to see what the students come up with!

This semester, the students have been performing one big 'literature review', and will now put their new skills in identifying knowledge gaps to the test by writing and defending a grant proposal. They did a 'pitch session' with their classmates, sent the 'program manager' (me) a 'one-pager', ...

And that's a wrap! We finished up Cenozoic Paleoclimate in the last millennium with @kimcobb.bsky.social's coral records and @michaelemann.bsky.social's temperature compilations 📈

It is inspirational to see paleoclimatologists be politically active, standing up for what the data show. #receipts 🌡️

It was a beautiful day today at @au.dk, so we took our paper discussion outside ☀️

We’ve transitioned now to the tropics to learn about sapropels, monsoons, landscape feedbacks, threshold responses, and more! 🌱

I try not to pick favorites, but my excitement was hard to hide 🌍

In the last few weeks, we’ve gone deeper into triggers, processes, and responses of the Pleistocene, with lessons from the MPT (including a lovely virtual visit from @jfarmersalmanac.bsky.social!) and the ice core records. A highlight for me was stepping through the logic of Shakun et al 2012 🙌🏻

Supurr interesting!

We’re hiring! The Bucknell Department of Geology is seeking a one-year visiting assistant professor to teach introductory level courses while I am on sabbatical. Happy to answer questions!

To be fair, if you did become a crypto girlie, I might be convinced to buy in.

After delving into the 57-record-stack of LR04 and more, we took a little journey through time over nearly 50 years from Hays, Imbrie, and Shackleton (1976) to the new Barker et al. (2025) on distinct roles for precession, obliquity, and eccentricity the 100-kyr world. 🌐

Literally so exciting.

Over the past few weeks, we've traveled millions of years through time past the EOT, MMCO, and MPWP (students LOVE acronyms... not) with highlights from Goldner, Holbourn, Foster, Wara, Fedorov, Burls, and more.

Next, we transition to the glacial-interglacial world of the Quaternary! 🧊🌍 #LR04
