Call for abstracts #EGU25 on developing new biomarkers! #EGUbiomarker. Abstract submission is now open! Organized by Jingjing Guo, @hallbergpetter.bsky.social, Nora Richter, Addison Rice and myself. tinyurl.com/4422wwr7
Screenshot of the following text:
Lipid biomarkers: novel applications, calibrations and tools for environmental 
studies
Lipid biomarkers are valuable tools for reconstructing a variety of environmental processes in modern 
and (geological) past settings. We seek studies that develop new lipid biomarkers and methods for 
applying biomarkers to modern settings and the geologic past to reconstruct environmental 
parameters such as temperature, precipitation, biogeochemical cycles, anthropogenic activities, and 
vegetation. These can be studies on the biosynthesis and phylogeny of source organisms, transport and 
diagenesis, calibrations to environmental parameters, proxy interpretation and applications to reconstruct past environmental conditions.

Silicate weathering of uplifted rock depletes atmospheric CO2, but oxidation of revealed rock organic carbon supplies CO2, offsetting depletion to a degree dependent on regional geological history.

If direct air removal costs $500 per tonne, removing just US emissions would cost ~$3 trillion per year (that's ~4x US military spending). It would also require twice the total power generation capacity of the US today (and it has to be carbon-free). thebulletin.org/2023/12/dire...
