Just to follow up, we may not entirely understand the system but we know that elevated air CO2 (sand) is not good for it. Job 1 is then to stop air CO2 from increasing. Given that we have thus far failed to do this, what are the ethics of actively discouraging research on any CO2 management methods (engineering or otherwise) that might help us in this task? Ethics, economics, and politics should enter the equation once research tells us if we actually have any technically and environmentally viable options. Or is SRM the only ethics target here? Or simply any "engineering"? Or anything that disturbs pre-1750 BAU? Greg

Model results indicate that throwing some oil on the gears will help make the clock run smoothly, despite not knowing how all the gears really fit together. When efforts to stop throwing sand fail, where does hubris lie? Does it reside in the person who wants to consider oiling the gears or in the person who claims a priori that their heightened ethical sensitivity demands that the gears not be oiled (as we watch the clockwork mechanism grind to a halt)?
