Working on solid Earth dynamics at GFZ Potsdam. Worried about too much CO2 in the atmosphere. Born at 316 ppm (seasonal minimum). Here private; opinions my own!

instead of writing reviews or proposals, answering mails, contribute to to other researcher's work, filling out forms etc. I think we actually got some nice results addressing continental lithosphere density and buoyancy -essentially what makes continents stick out to their elevation above sea level

I can only recommend to offer such internship, because in an effort to give the intern an impression of what a scientist ideally does in his working time, I managed to set some time aside to actually pursue, together with him, an independent own little research project which I thought of (continued)

I am very glad to share that I first-authored the very first paper published in the new diamond-open access (meaning it is free to publish AND free to read) journal Geodynamica. This paper lnkd.in/eyPAdx2X actually grew out of a high school student internship. (continued)

That's interesting! It would be in the right location at the edge of the slab in the transition zone (see our Figure 1a) like Eifel and Massif Central, but I haven't looked into whether other observations there would also be in agreement with our proposed mechanism.

What happens if subducted slabs interact with hot material at the base of the upper mantle? In Yingying Li's first paper doi.org/10.1029/2025... we show how this can lead to (secondary) upper mantle plumes. With @sasbrune.bsky.social, Eline Le Breton, Anne Glerum and @michapons.bsky.social.

As the calendar year begins, a reminder of the rapid acceleration of carbon dioxide concentration in the atmosphere, driving increasingly severe #climate changes. Shown are the past 2000 years of CO2 concentrations.
Stop burning fossil fuels.

Graph showing 2000 years of CO2 concentrations in the atmosphere. The levels are almost constant at around 280 parts per million until the beginning of the industrial revolution and the burning of fossil fuels and then the curve shoots up to 428 ppm now.

Even after 10 years, it is still important (and necessary) to demonstrate for compliance with the Paris Agreement on climate change.

Um das meiste aus dem CO2 footprint für die Forschungsfahrt im Pazifik zu machen, mache ich viele Zwischenhalte und vermeide Flüge wo möglich. climatewednesday.org/von-taipei-n... Sicher mehr Organisationsaufwand als fliegen, aber man sieht viel mehr und es ist ein großartiges Erlebnis.

Meinung: Emissionshandel: Kippt die EU den Emissionshandel, gibt sie die Zukunft auf

In der EU wächst der Widerstand gegen die marktwirtschaftliche Bekämpfung der Klimakrise. Setzen sich die Fossil-Fans dabei durch, heißt das: Europa subventioniert die Katastrophe herbei.

Koko Seamount (Emperor Chain) on 5-6 km deep ocean floor supposedly reaches up to -26 m! Last night Hakuhomaru passed there. In 2001 on Joides Resolution we drilled basalts to document Hawaii hotspot motion www.science.org/doi/10.1126/.... Amazing I would come to this remote place twice in my life!

A cloudy day on Hess Rise. In 2019 we wrote doi.org/10.1029/2019... on the origin of Hess Rise, I can't believe now I'm actually here, on board of Hakuhomaru. But we actually want to look in the mantle beneath, for vestiges of material emplaced by the Hawaiian Plume during Emperor Chain formation

3rd paper from @poulamiroy.bsky.social's Ph.D. just out at doi.org/10.1029/2025.... Combined global models of mantle flow and anisotropy constrain deformation mechanisms and viscosity, density and hence compositional structure of lowermost mantle.

This only considers sediments and there is probably a lot more storage capacity in basalts (e.g. Oelkers et al., 2023; doi:10.1016/j.ccst.2023.100098). Regardless, emission reduction need to be first priority, and CDR only for unavoidable emissions and removing what is already too much in the air.

My first boat trip this year - to Pfaueninsel. The next one will probably be slightly longer - a research cruise from Honolulu to Tokyo. Stay tuned for more details!

Friends and colleagues in Potsdam, Berlin, Brno and Vienna—next week I'll be on one of my bundled trips in Central Europe. If you're in the area I'd love to see you at one of the 5 public events I'm doing (in addition to many others) - or you can watch the live streams! See below for more.
