It's also why I've sort of resigned myself to a cynical optimism that the worst won't come to pass. The rich are not going to tolerate losing money. They will force through geoengineering stopgap measures that will save us from catastrophic warming, at the cost of unknown consequences.
This is why I vehemently disagree with those who say we shouldn't be conducting research on geoengineering. It will be done. The only question is, will we have done enough research to understand the potential consequences, or not?
