To Greg, This is somewhat off the topic of categorizing geoengineering approaches, but I need to respond to your warnings about considering biological remedies for climate. The remedies being considered in this category are almost without exception simply reversals of damage done by humans, so the alarm about "massive restructuring" of landscapes is painfully ironic. Deforestation, desertification, oxidation of soil by chemical agriculture - aren't those the massive restructurings of land use that have gotten us here?
Similar alarms have been raised about biochar use, a topic that gets some traction on this list. The assertion that biochar could be scaled up to accomplish substantial CDR led some to infer that there were giant plantations being planned for feedstocks. Again this is ironic since the only giant land grabs that are succeeding are for projects such as palm oil. So I would urge this list to allow biological methods an equal place at the table. As Adam points out, plants annually cycle massive amounts of carbon. Enhancing abd assisting biological methods of CDR should not be dismissed since photosynthesis is well understood and proven. Without plants we would have been cooked long ago. And if we let things go the way they are going we may end up without plants.
