Wild deciduous forests leave (hah!) a lot of carbon in the soil that is created. The soils that Europe has strip-mined of carbon were built up in a relatively short period after the last ice age. IIRC the rate of soil build-up in some places was about a foot per century. > Once again the stated goals do not meet with the proposed actions. Yes, photosynthesis is far too slow to be useful at the required scale and in the required timeframe. Accelerated weathering of olivine[1] could work and be cheap enough. Rock weathering is how carbon dioxide is actually removed from the atmosphere over the long term. Accelerated weathering works by increasing surface area of the rock and temperature to increase chemical reaction rates. > ulterior motives I don't think that this is nearly as big a problem as the sheer innumeracy of the political class, and their refusal to look at the problem squarely. 1. https://old.reddit.com/r/slatestarcodex/comments/pc0reb/an_attempted_primer_on_olivine_weathering_as/ https://old.reddit.com/r/slatestarcodex/comments/pc0reb/an_a...
