Artificial trees are not considered geoengineering since they are just reversing the CO2 released. The really sad aspect is we are not putting in the R&D resources needed to develop them to the required scale. No matter what we do about preventing the release of more CO2, we need to deal with the CO2 that has already been released.
- tim333 10y agoRegular trees work quite well and are cheaper. You just have to harvest them and not burn the wood, or turn it to biochar.
- chris_va 10y agoActually burning the wood works just fine, provided you can sequester (see BECCS, along with recent developments in basalt based CCS).
- danieltillett 10y agoThere are not enough natural trees to do the job because we have taken most of the really productive land to grow food. While there is some potential to use biochar in some locations, it is not going to be enough to get the CO2 levels down at the pace we need.
