I agree that "generate less wealth" is a non-starter. Any political efforts down that road are wasting time, in my opinion. And if you think this is an important issue, why waste time on something that's not going to happen? It does seem likely we can have a somewhat lighter footprint, or at least a more efficient one. The problem that lurks down that path is that if energy became more efficient it's possible people will just use more to do more, and the end result stays the same or even increases. So I do think things like geoengineering and adapting to the changes have to be on the table. It's getting to a point where it seems irresponsible to not be exploring those options more fully.
