There is about 1000 gigatonnes of excess carbon dioxide in the Earth systems from the burning of fossil fuels. It is already THERE, and will not naturally return to the lithosphere in less than thousands of years. So that is a really terrible deal for sure. Of course we should not keep adding to the problem - we must get off fossil fuels as quickly as possible. But there are likely to be some hard-to-eliminate uses and there is already this giant legacy of CO2 we have to deal with. I don’t think we have any actual choice to not do carbon dioxide removal - not and retain an appreciable percentage of the world’s biodiversity.
