The climate geoengineering is already inevitable to avoid imminent global climate disasters. Even extreamly cautious approach is not enough for any grand-scale practices of climate geoengineering as we never understand the complex global climate system exactly. However, modern human beings have unintentionally done the global-scale climate geoengineering that increases the atmospheric CO2 level with the wide-spread massive burning of fossil fuels. The CCS-geoengineering in the broad sense includes the CO2 capture and sequestration, CO2 capture and CO2-EOR/EGR, air capture and sequestration, air capture and CO2-EOR/EGR and also underground microbial CO2 recycling. The CCS-geoengineering only reduces the artificial emission of CO2 into the atmosphere or suck the excessive CO2 from the atmosphere. The CCS-geoengineering is a naturally safe geoengineering technology as the CCS-geoengineering restore the atmosphere only toward the natural CO2 level minimizing untoward effects.
