First of all, wealthy people typically have multiple properties, in different places. So it's not like they are going to be homeless if they lose their villa in Florida. Second, they probably already risk hurricanes and tsunamis. Third, the predicted sea level rise is about 1 meter (if we don't count the land ice, which is unpredictable), so you can probably deal with that on one house (but much harder on city or nation scale). In short - if you're rich, you're still better off than others in case of global catastrophe, so there is little you can make in preparations. But I am an expert in habits of wealthy people, this is just a guess. I agree with Steve Pinker, but if you actually read the book, it's not without caveats. Regarding attribution, we can somewhat attribute the drought to climate change (because we know from models that there is expected to be more of it) and so the conflict; it's not the sole cause, but it's a factor. I have no doubts there are going to be more mass migrations due to climate change.
