My opinion is that geoengineering solutions lead to more fragility than reducing emissions and we would be better off avoiding them or at least doing something along the lines of carbon sequestration and not SRM.
Sure, I think carbon sequestration is a solid approach as well (especially given that it’s still net energy-producing to burn fossil fuels and sequester the resulting output as CO2 somewhere underground!), and am not familiar enough with the numbers to know if SRM is better or worse than sequestration. My core objection was that Russell’s opinion of the NAS meeting wasn’t “SRM has expected disasters or expected high costs that disqualify it”, and instead it looked like that the NAS thought it was more important to be adversarial to fossil fuel interests than make the best engineering decision.
