Iron fertilization is arguably simpler— don’t need to own the land and it can be scaled. https://en.wikipedia.org/wiki/Iron_fertilization https://en.wikipedia.org/wiki/Iron_fertilization The use of mass timber for construction is a great way to make sustainable forestry sequester carbon for the long term. https://research.fs.usda.gov/treesearch/66069 https://research.fs.usda.gov/treesearch/66069 Cloud seeding via containerships is another low cost, high impact method: https://en.wikipedia.org/wiki/Marine_cloud_brightening https://en.wikipedia.org/wiki/Marine_cloud_brightening But if we really want the ability to pause climate change, we need to do some more research on Stratospheric Aerosol Injection: https://en.wikipedia.org/wiki/Stratospheric_aerosol_injection https://en.wikipedia.org/wiki/Stratospheric_aerosol_injectio... Stratospheric Injection of Calcium carbonate is a very promising approach that would have the benefit of reducing ocean acidification.
