Papers counted in the census#
6 CDR-relevant papers and preprints since 2021 count for the top lists, by pathway: Biochar 6, Enhanced Weathering 1. A paper tagged with two pathways counts in both lists. Preprint and journal version are merged where OpenAlex links them; where it does not, both appear. Under each title: the venue, the co-authors (linked when they have a profile page) and the strongest OpenAlex keywords; the pathway column is my own tag.
