Preventative measures haven't necessarily failed entirely. The renewable power and battery electric vehicle revolutions are underway, and vastly more successful/rapid than almost anyone predicted. But, they need more time. I see geo-engineering as a way to buy time for the science and engineering needed to solve the problem without austerity measures. (unfortunately, while austerity would have allowed us to attain the Paris targets, it was a political lead balloon from the start)
