This is in part the work of Robert Bogue, with John Stix & Peter Douglas.

Diffuse CO2 emissions can permeate to the surface and can stimulate plant growth, preceding any deformation, heat, or other warnings of an impending eruption.

A thought-provoking talk by Dr. Jobst Heitzig of Potsdam Institute for Climate Impact Research on building a framework for combining physical processes of the Earth system with human interactions (politics, public opinion, etc.). Objects can be gridded data, groups/communities, or individuals; they can be part of natural systems, human-environment interactions, or cultural constructs. Sometimes several at the same time.

‘We’re All Asgardians’ a talk on the origins of Eukaryotes (us) with implications for our present-day immune systems by Brett Baker, University of Texas, Austin. Dr. Baker inaugurated the EPS Wares Distinguished Public Lecture series.

Eukaryotic cells are most closely related to the 'Hod' branch of the Asgard branch of the Archaea.

🌐 NFDI4Earth at the 1st Base4NFDI User Conference (UC4B2024)
https://base4nfdi.de/news-events/events/user-conference-2024

This week, a part of the NFDI4Earth team had the pleasure of participating in the 1st Base4NFDI User Conference at Fraunhofer FOKUS, Berlin.
The event provided an excellent opportunity to network, exchange work in progress, and dive into the exciting developments surrounding the Base Services.

Congratulations to Dr. Pascale Daoust, who successfully defended, "Ocean Acidification: Insights from the Behaviour of Ancient and Modern Carbonates", supervised by Al Mucci and Galen Halverson.

The work involved field and laboratory studies of the Paleocene-Eocene Thermal Maximum section near Campo, Spain.

The figure shows the depositional environments at the time; from Daoust et al, submitted, modified from Pujalte et al. (2014)

An amazing talk by Max Lloyd of Penn State University. He used clumped isotopes to separate the effects of CO2 abundance, water availability, and temperature on plant stress. The plot shows the clumped signal in lignin from recent trees but he has analyzed samples from the last glacial maximum. An implication is that even in a high-CO2 world, water and heat stress reduce the ability of plants to produce biomass.

Plots showing the effect of growing season temperature and atmospheric CO2 concentration (greenhouse and natural) on a particular clumped isotope signal in the tree's lignin. This and similar data, combined with modelling, allows the measured clumped isotopes to constrain plant stress and biomass production.
