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!

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.

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.

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!
Happy to share that our recent paper on global-scale geodynamic + seismic anisotropy simulation is on Eos spotlight. With @bstein.bsky.social , Manuele Faccenda , @michapons.bsky.social
Enjoy reading! :)

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. With Manuele Faccenda, @michapons.bsky.social & me.

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.

Mark the date: On July 15, it will be possible to submit articles to geodynamica.univ-lyon1.fr - it will be completely free for both authors and readers! I'm glad to be on the editorial team. Don't let some money-grubbing publishing company get between you and your research results; publish with us!
