"There is only one reason to consider deploying a scheme with even a tiny chance of causing such a catastrophe: if the risks of not deploying it were clearly higher. "
Why does this caution not apply to policies and regulations aimed at reducing greenhouse gas emissions?
I guess I don't understand why this needs to be explained. The situations are not equivalent: Doing something harmful (to your body, to your car, to your environment) can be reasonably stopped without much concern that the results would be catastrophic. If you are doing something you know is harmful and are trying to mitigate the effects of it, then it's reasonable to consider the relative harm of the original act versus the mitigation.
Yes, the costs associated with reducing CO2 production should be considered, but there is no reason to think that not producing CO2 in itself would be catastrophic, since that's what the status quo was for thousands of years.
