You mean synthetic, 100% engineered air capture is politically and economically unrealistic, whereas natural, biogeochemical air capture is an important economic and apolitical reality (see figure in the NOAA fact sheet) that we might learn from and improve on(?) See my last post. - Greg

Given society’s present reliance on fossil fuels, widespread adoption of CCS appears indispensable for meeting stringent climate targets. We argue that for conventional CCS to become a successful climate mitigation technology—which by necessity has to operate on a large scale—it may need to be complemented with air capture, removing CO2 directly from the atmosphere. Air capture of CO2 could act as insurance against CO2 leaking from storage and furthermore may provide an option for dealing with emissions from mobile dispersed sources such as automobiles and airplanes -- You received this message because you are subscribed to the Google Groups "geoengineering" group.
