Geoengineering on our only home is extremely dangerous. YC proposed desert flooding for carbon sequestration http://carbon.ycombinator.com/desert-flooding/ http://carbon.ycombinator.com/desert-flooding/ Even if you assume the energy demands aren't an issue, and you could build these shallow pools, and find something to do with the captured carbon, you've probably just killed the Amazon by turning the Sahara into a series of ponds as the Sahara fertilizes the Amazon. You've probably also just caused insanely disruptive, and potentially catastrophic, changes to weather patterns by introducing obscene amounts of new moisture into the air over the Sahara which would almost certainly impact the entire planet's weather patterns. Oh, you say you want to make a new tree that sequesters carbon better or is more ideal for reforestation? Like, oh, Maddie Hall is trying to do with Living cabron? Alright, great. But have you thought about the massive mycorrhizal networks that support forests, or the thousands of species per cubic meter of soil, or the fact that things that grow faster tend to fall over much easier and that the massive trees of the world are extremely slow growth, have you thought about how fast minerals might be stripped from fast growing trees, changes to weather, impact on the water table, did you just make a horribly invasive species, are you creating a tree that's a candy-filled playground for invasive insect species, is the species now outcompeting native ones that are necessary for any number of other species? Etc., etc., so on and so forth.
