Seems to me that fossil fuel carbon sequestering in baking soda has less problems to it than putting carbon in bags at the bottom of the ocean that would eventually deteriorate or compressing it into mine shafts/salt domes. But I've yet to see a Pop-Sci article on agrichar (creating charcoal from biomass, that not only enhances soil fertility but produces fuel as a byproduct. The net affect is enhancing land, sequestering carbon , and producing a green alternative fuel). Perhaps its because most of the research appear to be international and not appearing on most AP feeds. In any case I'd like to see a more detailed description of how agrichar is produced and how "carbon" credits" would help agriculture adopt it . I only ran on to this topic indirectly on a Google search this morning.
