On The Climate Brink: Stop emissions, stop warming: A climate reality check This is a crucial point because it determines how much warming is already "locked in" and effectively unavoidable. The answer is very little warming is locked in. Also, this is our 100th post! www.theclimatebrink....

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.

Comes on top of a paper 1 year ago suggesting organic carbon weathering offsets silicate weathering. So we now would appear to have mountain building as a source of CO2 not a sink. Im not sure that's tenable. www.nature.com/articles/s41...

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.

This will be an interesting day to reflect on in the future. "Battery cells at $50/kWh means the technology to decarbonize most of road transport globally is already here, as opposed to in some future scenario." EVs are cheaper than ICE now. Today.
