[HRE31-01] CCS-geoengineering: the only one reasonable climate geoengineering technology at present

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.
