| Summary: | Current investment to address climate change is focused mainly on the mitigation offurther greenhouse gas emissions by a wide variety of means and a handful oftechnologies, most of which are designed to extract carbon dioxide from the air andto either to sequester it geologically or to turn it into biomass or useful products. Thishandful includes Direct Air Capture (DAC) using machinery, Bioenergy with CarbonCapture and Storage (BECCS), and various forms of Afforestation. Even with somelikely improvement in cost over time, most reputable analyses indicate that all threewill suffer from showstoppers in the form of one or more of: scalability, cost,insufficient resource, timeliness, or risk of reversal under increasing global warming.In addition, none directly addresses the problems of other greenhouse gases, ofsolar or thermal radiation management, of ocean acidification and stratification, ofspecies and habitat loss, of ice loss, of increasingly extreme weather events, of sealevel rise, of passing tipping points, and of the long-term effects of prior emissions,land clearing, pollution, and ecological impoverishment.OFFERWhat is offered below are sixteen conceptual methods, the combination of whichaddresses both carbon dioxide removal (CDR) and the above other problems indifferent ways. Most require validation, modelling, gated testing and approval prior todeployment. Whilst research is being undertaken at various organizations todevelop, quantify, model, test and validate some of them, all such concepts thatappear to have prospect need to be evaluated and compared. As well, all should beassessed for their potential cost-effectiveness, their effects, scalability, risk-to-riskprofile, optimal interaction, measurably, reversibility, and community acceptability.Readers are requested to see how they might contribute to these efforts.Each concept will be given a short description. Its key functions will be outlined, aswell as the innovation dependencies on which it depends. Attached to it may also bea summarizing ... |
