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

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 ...

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!

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 🌍

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.
