It seems to me only fair that we should not attempt to address it using solutions whose consequences we cannot fully understand or predict. SRM appears to me to be fraught with impossible risks particularly with regards to its impact on rainfall patterns (perhaps there are even greater risks, I don't know). Second, SRM does nothing about ocean acidification so it's a half solution at best even if it works as intended and without adverse consequences. CDR, on the other hand -- carbon scrubbers in particular -- appear to me inherently superior as it addresses the root cause of this problem. The only unresolved issue here is what to do with the captured carbon. It's not a small problem but it can be addressed. Since we have limited time, limited resources and limited budget, should we not focus on solutions that are promising rather than those that are inherently risky? Is it even possible to eradicate all the uncertainties related with SRM in the next decade or two?
