No so probabilistic, but more like a linear combination of approaches maximizing for gain function and economy of scale. I can tell you with certainty planting trees is far down on the list. At the top of the list would be strategies that utilize biological processes as the capture component of CCS. Kelp and phytoplankton robotic oceanic aquaculture seem the most obvious. Going GMO to increase yield and reduce needs for micronutrients would probably be helpful. Terrestrial CCS would look like either chemical processes or DACCS. I think the Microsoft approach has legs to it if it can be demonstrated, Omniprocessor-style. For soil health and to combat desertification, it would be wiser to stop rain forest loss and reintroduce megafauna across the world to improve non-wooden plains / semi-wooded land.
