One problem is that with current technology, it is quite expensive to prevent extreme climate change. With emissions reductions, it is trillions of dollars. Even with solar radiation management (a type of geoengineering), it is tens of billions of dollars. Depending on the type of solar radiation management, it could result in rapid warming if turned off by another catastrophe, causing a double catastrophe. But there are adaptation techniques that are cheaper (~$100 million). And since these techniques protect against many other catastrophes, I'm pretty sure they are far more cost effective than preventing extreme climate change. But it would be interesting to compare quantitatively different interventions in your model.
