Again, without salient details my fear is that this is the pop-science version of clickbait. I'm surely do hope I'm wrong, but unless these are fundamentally new CDR scenarios that have not yet been discussed anywhere in the geoengineering literature, my confidence in the claim that we can somehow "reverse the build-up of atmospheric carbon within thirty years" in the absence of radical technological change will have to remain discouragingly low.
